What's Philosophy and Paul Graham
Xah Lee, 2010-10-10
Discovered:
* 〈How to Do Philosophy〉 (2007) By Paul Graham.
http://www.paulgraham.com/philosophy.html
I find it LOL.
He says:
Formal logic has some subject matter. I took several classes in
logic. I don't know if I learned anything from them. [1]
[1] In practice formal logic is not much use, because despite some
progress in the last 150 years we're still only able to formalize a
small percentage of statements. We may never do that much better, for
the same reason 1980s-style "knowledge representation" could never
have worked; many statements may have no representation more concise
than a huge, analog brain state.
Eh?? What formal logic is he talking about? Taken at face value,
formal logic is synonymous to symbolic logic, mathematical logic, or
logic by formal languages. We thank formal logic for computer algebra
systems such as Mathematica, and much computer language advancements
such as lisp, OCaml, Haskell, and math proof systems or assistants
such as HOL. (See: The Codification of Mathematics; State Of Theorem
Proving Systems 2008.)
So, clearly he doesn't mean this. Perhaps he means Syllogism or
propositional logic. You know, basically reasoning by words, in
classical philosophy. But without these, formal logic as we know it,
including so-called “boolean algebra”, fundamental to computers,
wouldn't have developed.
What is Philosophy?
The whole essay is quite valueless to me. Let me tell you what
philosophy is, it's essence: Philosophy is THINKING.
Thinking, when done in a serious way on a subject matter, that you do
hard, think, think, think, keep thinking, then write down your
thoughts, and think more, think about your thoughts, try corrections,
and observe and learn and think more, doing this for months or years,
until, you might have something to say about a subject, even if the
conclusion is “i dunno”, then, it is philosophy.
Philosophy, is the root of sciences. In the beginning, science, art,
poetry, religion, philosophy, are all kinda mixed up together as one
subject. Then, they gradually diversified. In particular, philosophy
turned into today's cosmology, astronomy, medicine, geometry,
chemistry, physics, math, linguistics, biology... More concretely,
when some question is resolved by what we call scientific methods
today (e.g. observation, experiment, analysis, prediction), they are
not called philosophy anymore, but science. But, if you answer the
question by basically just thinking, or thinking with other methods
that we don't have a name for yet, that's philosophy!
Paul's essay, the elaborate 4.7k words, is the epitome of philosophy!
You can see, that he is thinking, thinking, and the subject of his
thinking is “philosophy”, or “how to do philosophy” as his title
suggests. And, what's his method? Did he go by the science of
statistics? social science of poll? Systematic analysis of literature?
Archeology of examing cultural artifacts? CAT-scan of philosopher's
brains? No. His method, is just thinking. Thus, he's doing philosophy
right there.
However, in his essay he thinks that philosophy is useless. Without
his interest and college major in philosophy, he wouldn't be what he
is here today, and may not be as successful, and of course wouldn't
write this essay about philosophy.
Philosophy, or call it thinking seriously, and in watered down form is
called “critical thinking” in today's universities, teaches and trains
you one thing: think! And that, is fundamental to intellectual
pursuits, even if you end up not understanding the so-called classic
philosophical subjects and its history, such as Plato, Aristotle,
Kerkeley, that Paul cites.
The culminating point of Paul's essay is this proposal:
...Instead of trying to answer the question:
What are the most general truths?
let's try to answer the question
Of all the useful things we can say, which are the most general?
I think is quite silly. He characterized philosophy wrongly and
narrowly, by linking it to just metaphysics, and somehow, seems to
have a fetish towards Aristotle.
Aristotle is a dead figure, and so is metaphysics. I doubt that these
subjects are more than 1% of the subject matters of journals and
publications among today's philosophors.

That's right. And such logics don't capture very much at all about how
humans reason, which was the original intent in developing them.

That logic may have had a few valuable offshoots, does not obscure
Graham's main point that the development of logic completely failed in
its original goal (which was to systematize the process of doing
mathematics, aka meta-mathematics).

No.
All that is clear, is that you don't understand what he's talking about.

Let me suggest that, among the vast array of possible human readers,
Graham's essay on philosophy holds considerably more value that yours
does.

True enough. But there are some questions that have remained constant,
and were asked thousands of years ago in the beginning of philosophy,
and continue to be explored by "philosophers" today. These explorations
are often thought of as the "core" of philosophy, and this is what
Graham is criticizing.
The parts that peeled off, were useful. The parts that remained
... were less so.

Really? And just what subjects do you think have occupied the bulk of
philosophic journals and publications in the last century?

a. Graham repeats he does not understand philosophy.
"I'd tried to read a few philosophy books. Not recent ones; you
wouldn't find those in our high school library. But I tried to read
Plato and Aristotle. I doubt I believed I understood them, but they
sounded like they were talking about something important. I assumed
I'd learn what in college."
"I'd give Berkeley's Principles of Human Knowledge another shot in
college. Anything so admired and so difficult to read must have
something in it, if one could only figure out what.
Twenty-six years later, I still don't understand Berkeley. I have a
nice edition of his collected works. Will I ever read it? Seems
unlikely."
"Formal logic has some subject matter. I took several classes in
logic. I don't know if I learned anything from them."
b. Nevertheless has no problem in intimating it is all a bit of a
waste of time and spends the next few pages telling us all about it.
Generally I would say that reading this essay is a waste of time.
If you want to learn the subject, go to somebody who actually knows
it. Russell's 'History of Western Philosophy' and Passmore's 'A
Hundred Years of Philosophy' will take you to 1970. And if you want
to understand Wittgenstein, read Kenny. And if you want an antidote
to Wittgenstein, read Gellner and Popper.
Mark
That's not what your quotes show. Graham learned the material that was
taught in his classes. What he realized, was that there was no real
content there. That's different from not understanding the content.
> Generally I would say that reading this essay is a waste of time. If
> you want to learn the subject, go to somebody who actually knows it.
But what if you wonder whether there is anything valuable in the subject
to learn, in the first place?
Studying a history of the subject will tell you what happened, and what
various people thought at different times. It won't tell you whether
the entire field is a self-indulgent mistake.

Sorry; that is exactly what he says. He tried Berkeley, 26 years
later he does not understand Berkeley, he just has the books. Oh wow.
"Esse et percipi aut percipere" passed him by. He took logic but did
not get much from it - so that's most of Russell, Quine, Davidson,
Tarski out of his reach. Without really getting that background, how
can you make a judgement? That's a good chunk of C20 philosophical
logic. Realism, constructivism, semantic paradoxes - philosophy of
maths. Semantic theory of truth. Verificationist theories of
meaning. Possible world semantics, Kripke models, counterfactual
conditionals? Forget it.
The guy doesn't know the subject. And you cannot pass a worthwhile
judgement on anything unless until you have taken it to a certain
depth. It is not worth reading PG's amateur extemporisation on
philosophy and almost not worth commenting on it except that somebody
*might* be influenced and lose out on the chance to read something
really worthwhile from any of the people I just mentioned. That's the
only reason why it is worth making any comment at all.
And that's it from me. I'm not taking this further because the
internet will always generate more junk than any one person can deal
with. Replying to junk seems to generate more. This is not the place
to discuss philosophy. Signing out.
great post Mark.
just by your few paragraphs, the names and terms you mentions (and of
course the way you said it), makes me believe that you know more about
philosophy than me, and, if you write a blog on philosophy, i
certainly would pay much more interest.
On the other hand, Paul Graham's blog on philosophy, just lol. But you
know, it goes with fame. Lots of tech geekers read him, just 'cause he
is a expert programer and is successful. Same with perhaps Bill Gates
who wrote books about the future. And in general, lots of celebrities,
or experts of something (say Nobel winner), once they became well
known, they start to fart on everything, from politics to human nature
to science, and the masses follows it.
--------------------------------------------------
Some general advice for my readers:
Most comp.lang.* readers, are
idiots at everything. (actually, this can be said for anyone anywhere)
The comp.lang dwellers are expert in one very specific thing. For
example, if i ask what are the tech details of lisp's package system,
then some regulars at comp.lang.lisp indeed can provide basically the
best answer possible. If i wonder about some particular history of
lisp, there's Kent Pitman, Richard Stallman, and few others, who's
opinion on this can be taken seriously, because, they invented it,
lived thru it. Same for, if i have a perl speed question,
comp.lang.perl guys knows it, such as Randal Schwartz. However, their
opinions, on lang design, which lang is good or best, on lang
evolution, on economics, on licensing, on writing, on AI, on user
interface, on IT corporations, which are perennially 50% of the posts,
are worse than shit. And the worst problem is that they dunno
that. One example to tighten it: Larry Wall perl, Guido python, lisp
McCarthy, these people, their opinion on language design, on
functional programing, would be shit-like. Same, vast majority of
authors who have written books, their opinion on writing, grammar,
linguistics, would be shit-like, even they are best sellers. Computer
scientists (such as often in comp.lang.scheme group), their opinion on
programing would be idiotic shit. Professional mathematicians,
their opinions on math notation, are fuck-ur-ass idiotic.
if you want really good opinion on lang design, ask those specialists,
who spent several years surveyed tens of langs as a _social research_,
and as a _background_, they might also have the ability to code
non-trivial programs in tens of langs, and possibly also with
associated background of basics of linguistics, computer science
proper, math, logic, psychology, cognition. Typically, we don't even
know who are such people, and vast majority of them are not known to
the general programing public.
if you want good opinion on math notations, or comp syntax design, you
get it from specialists on just this very issue, who's math knowledge
or comp programing knowledge might even be below u n me.
such narrow specialists exist in every of the ten million fields, and
their publications, exist, but u have to spend time and money to dig
them out. What iditos i deal daily in comp.lang is like: “Xah is a
troll, because he thinks Larry Wall is wrong to claim perl supports
functional programing.”. “Xah is troll, because he thinks McCarthy is
wrong on some functional programing issue.” LOL. Yes, i think they
know shit, except they are inventors of their langs. I know more about
lang design, functional programing, than them, anytime.

1. It is not practical.
The first is that this is a form of knowledge from which you cannot
'do anything practical'. That is, you cannot fix your car, get a
better house or make money from it. Of course philosophy mainly never
promised those things and I do not see why everything
should be weighed in those terms. I think that this mind set is more
common now than when I was young, simply because people pay for their
education and expect value for money. i.e. the prospect of more money
in return. Philosophers historically often showed great disregard for
this mind set.
2. It goes nowhere.
The second is that 'philosophy never gets anywhere'. 'Philosophers
just argue round and round'. I would deny this one. What is true is
that philosophers sometimes end by saying that a certain proposition
cannot be known to be true (eg. 'God exists'), but this
is a form of (meta)knowledge in itself. Aristotle says that we should
not expect more in certainty from a subject than it is capable of
delivering. As Socrates pointed out, knowing what it is one does not
know is a wisdom in itself. But philosophy does deliver results that
are not just metaknowledge; Russell's destroyed Frege's Axiom V in the
Grundgesetze in a single letter written in 1903.
3. It is an attenuated husk left over from the evolution of other
subjects.
This is a position sometimes held by people who have done a little
reading. The word 'philosophy' splits into two parts 'lover
of' (philo) and 'knowledge' or 'wisdom' (sophia). The word is
indicative of the ancient roots of the discipline back to a time when
human knowledge was far less differentiated than it is now. It
lingers in the title of Ph.D. which is dished out in many subjects.
The story is that once everything was philosophy, but that gradually
all the other sciences seperated out from it, leaving only a husk of
subjects too dull or intractable for others to bother with and this is
what philosophy is. This is probably encouraged by reading the
effluent of many academic philosophers who are simply cranking out
stuff to a quota.
I believe that this is wrong. One can see it in different terms. We
might say, that just like our planet, scholarship and human knowledge
was once highly liquid, molten you might say, without clear
boundaries. As civilisation progressed, the knowledge hardened and
floating plates of hardened thinking were created and people made
livelihoods by living on those plates as physicists, mathematicians,
economists etc. But the boiling magma still exists underneath and in
times of conceptual revolution, when old ideas are overturned, it
comes boiling up.
Thus you will find in Relativity theory, ideas about space and
position which were anticipated by Leibnitz in his contests with
Newton 200 years before. In mathematics we found in the C20 that we
are not rooted on a rock but floating on this awesome primordial lake.
This brilliant, awesome display of light and mental force that bursts
out in times of a revolution of ideas is philosophy.

There's a big, big, big difference between "he didn't understand the
material", and "he understood it, but didn't get much [value] from it."

Right.
> 'Philosophers just argue round and round'. I would deny this one.
Philosophers have examined some questions for thousands of years, and
written tens or hundreds of thousands of words about the questions. "Do
we have free will?" "What is the meaning of life?" "Which actions are
ethical?"
These questions have started to have some actual answers in recent
decades, but the answers come from computer science or cognitive science
or evolutionary biology, not from the thousands of years of "work" in
philosophy.
All this work hardly builds on itself, and doesn't lead to any
conclusions. If you look at an introductory philosophy class in
college, what you find is a lot of "in xxx date, philosopher yyy had the
opinion that zzz."
Consider any other field of study. Do you think there is a difference
between "the history of thought in physics (or cosmology or biology)",
vs. "an introduction to the best current thought" in the same topics?
Why is it that there isn't such a sharp distinction in philosophy? Why
is "introductory philosophy" essentially the same as "the history of
philosophic thought"?

This is the BEST that philosophy to aspire to: perhaps some claim will
be found to be inconsistent.
But that's basically all. If your thoughts have internally consistency,
then there is no further evaluation available from philosophy. All such
consistent thoughts have roughly equal weight.
Again, consider any other subject area. They're actually _about_
something, something external to the academic discipline itself. There
are lots of internally consistent physics theories; very few of them
match observational data.
Philosophy has no observational data.
> 3. It is an attenuated husk left over from the evolution of other
> subjects.
It is certainly true that, thousands of years ago, some work which was
then called "philosophy", today has a more specific name, and is
valuable to society.
The things that remain, still called "philosophy", were always there
from the beginning ... but they turn out to have been the least valuable
parts.
> Thus you will find in Relativity theory, ideas about space and

Einstein's insights were a consequence of the observational physics data
available to him at the time. No credit is due to any philosophy from
centuries before. That's simply not in the causal chain of how Einstein
figured out the secrets to Relativity.

> Philosophy has no observational data.
As it happens, I disagree with your statement that philosophy brought nothing
to humanity.
My reasoning is:
1. Philosophy is fundamentally about observation of external (the
world) and/or internal (the mind) phenomena and trying to find a
pattern in it or a reason for its existence. The observations and
pattern determination are reality and scale agnostic, which is a
pretty big concept to understand.
2. Those observations and patterns are only meaningful if we can use them
to predict or understand the behavior of the world or the mind. What tools
do these questions imply?
3. Mathematics, which could be reliably argued as a philosophical
conversation mankind has had with it self for several thousand years
and due to that has its own dialect, and science were proftable to
perform in order to answer the questions that philosophy presented
about observations.
4. Once answers (which are really tools) are produced, society as a
whole has an agreed upon (roughly) philosophical understanding of the
context of both the question and the answer in order to determine if
the result is actually meaningful.
Just look at the things animals without the concept of philosophy have
generated. Absolutely nothing! Well, maybe stick to get ants out of a hole
or a stone to break open a shell.
Without the concept and expression of philosophy, I assert that
humanity never would have been anything more than animals doing exactly
what is necessary, and only that, to survive. And it would have been
that way until our species died or changed into something else.
Dinosaurs had *160 million years* to get to the stars, but they never
could ask themselves why would they want to.
We had only 200,000 years. But we could ask why. At least we got to the moon.
The greatest tool mankind ever created was: "Why?" It has shaped and will
forever more shape our future in fundamental ways.

The distinction you are making here doesn't help PG much you know.
Yes re logic, 'didn't get much out of it' might mean
a. didn't understand it or
b. understood it and either found it dull or irrelevant to his
interests
But whatever interpretation we attach, in either case it is extremely
unlikely that PG ever got to study the more advanced material on
philosophical logic I have mentioned which requires sustained effort.
So what is his opinion worth? Can it be based on a real knowledge of
the subject? I suggest not.
> I know about all those things. You overestimate their value to the world.
Define 'value'. Is philosophy only justifiable by being useful to
things
other than philosophy? This looks like a variant of the 'not
practical'
criticism.

To a degree; but there are questions which are ethical which are not
answered
except by philosophical enquiry; for instance 'In what cases is it
right for the wishes of the majority to be suspended in favour of the
wishes of the minority?'. No amount of social research is going to
answer that one alone - you must embark on philosophy.

And much the same is still going on in the fundamental questions of
science.
Scientists are still trying to answer the questions that the pre-
Socratics
posed about where things came from and how they are constituted. What
we have is our best guess. According to Popper, that's all we can
ever have.

In this respect, philosophy is exactly like pure mathematics. But the
exercise of following a position to its logical conclusion is a useful
one. The results can be surprising. Mostly people do not have this
discipline; Russell remarked that the value of philosophy was that it
stopped people from assuming propositions that were emotionally
comfortable but not consistent. Socrates was a master of showing
people this - which was the reason for his execution.
> Philosophy has no observational data.
Well, actually a lot of philosophers have been skilled mathematicians
and scientists and have been quite comfortable with using empirical
data. Philosophers do not deny themselves the fruits of empirical
science; it is just that when we are doing philosophy we are not
actually performing experiments ourselves.
If we compare philosophy to pure mathematics, there is a pure and
applied aspect. We can take ethics into social policy or philosophy
of mind into psychology.

I would deny that. I do not believe that Relativity theory was a
*consequence* of observational data, because no scientific theory of
that generality can be entailed by the data. It was an audacious
hypothesis, triggered by perceived anomalies existing between the
speed of light as a constant and the Principle of Relativity itself
which insists that the laws of nature are the same for all observers
in all inertial frames. This latter principle is very sympathetic to
the thinking that Leibnitz sponsored vs Newton. We don't know if
Einstein knew of this philosophical
argument between these great minds or not. Even if he did not, this
does not detract from Leibnitz's insight.

I suspect that "has practical use" is the poor man's version of "it's
true". A very weak version of Truth indeed but, at least, verifiable.
By the way, I liked a lot your paper on gnosis. Will other writings follow?
gg
here's my own take on doubts about usefulness of philosophy. This is
also a subject on my mind for perhaps 10 years. Thanks for the
opportunity here to write it out for the first time.
to me, questioning usefulness of philosophy is questioning thinking
itself.
Typically, people think philosophy is not useful because when they
think of philosophy they think of things like “does god exist”,
“what's beauty”, “where do we came from”, “do we have free will”,
“purpose of life”, “what's good and what's evil”, etc.
These kinda subjects are what most people think of when hearing
“philosophy”. However, that's not what philosophy is about. Thus, the
common thought of “philosophy being not practical” is due to wrong
characterization of philosophy.
As i mentioned previously, philosophy is thinking.
• 〈What's Philosophy and Paul Graham〉
http://xahlee.org/Periodic_dosage_dir/whats_philosophy.html
and here's a Wikipedia quote on philosophy 〔 http://en.wikipedia.org/wiki/Philosophy
〕:
«Philosophy is the study of general and fundamental problems
concerning matters such as existence, knowledge, values, reason, mind,
and language.[1][2] It is distinguished from other ways of addressing
such problems by its critical, generally systematic approach and its
reliance on rational argument.[3] »
Philosophy, is the root of all knowledge. As said before, it's the
origin of all what today we call sciences.
Let's give a concrete example about how philosophy is thinking.
For example, among us programers, we often ask questions like “which
language is best”, “which language is most elegant”. We discuss these
every day. We argue about it. Some say Scheme, some say Common Lisp is
most practical. Some say Haskell is most beautiful. After some
discussion, our reasons and thoughts necessarily expand on meaning of
“beauty”, “elegance”, “practical”, or other contexts of each person's
opinions and experiences. For example, Scheme Lispers will say they
really like Scheme because it is so small a language and most
powerful, and perhaps the power/(lang size) ratio is largest. Perl
programer may disagree, and counter that Perl allows the shortest
number of chars for a source code, therefore the small here is better
than Scheme's smallness in lang spec, while perl has much more libs
than Scheme, therefore the Power/(actual source code) is maximized,
thus more beautiful than Scheme. Common Lispers might counter, saying
that yeah perl allows “golfing” but it's line noise, hard to read, not
maintainable, while Common Lisp, has huge libraries, huge lang spec,
huge number of practical industrial implementations, that once you
become familiar with the lang, it has most power for given task with
respect to programer. Perhaps, emacs share similar philosophy on this.
So, here, we have several different takes, and as you can see. What's
a name to describe these collection of thoughts? Philosophy! We
started from a practical, everyday question, that all of us seek the
answer, and eager to debate about it, we ends up with schools of
thoughts, what's best described by the word “philosophy”.
After few generations of this debate, the thoughts and debates are
organized into “school of thoughts”, so we have categorization of
thoughts on the meaning of elegance, practicality, beauty, of
languages. And, when someone wanted to create a new lang, as happens
today all over, he can look at this more organized philosophy of
computer languages, and benefit fruitfully, in his thinking about
what's is “beauty” and “practicality” in a computer language for him,
a direction of lang design.
(i'll mention here that Paul Graham's philosophy on this, about the

)
That's the humble root of all things philosophy: thinking. When the
fruits of thinking have amassed into a body of literature, it's called
philosophy. Thus we have philosophy of math, philosophy of language,
philosophy of science, philosophy of education, for examples. With
such established and organized thoughts, it directs our future
activities and thougts. It directly gives us directions for the
future.
In general, what's in our brain today, on society, on sciences, on
relationships, on sex, on politics, your mindset, your behavior of
every minute, are shaped by the accumulated thinking (philosophy!) of
the past. For example, in US, your thoughts on free speech, on
justice, on politics, etiquette, child rearing, on dating, on personal
hygiene habits, came from your education and family, which traces all
the way back to the ancient philosophers from the Greeks (e.g.
Aristotle, Plato.). While, Asian people, their thinking, manners,
behavior, are overall distinctly different from Westerners, because
thru generations they came from accumulated thinking from Asia, back
to the ancient asia philosophers. (e.g. Confucius, Lao Tzi, Buddha.)
To ask “whether philosophy is useful” is like asking whether
accumulated thinking of all humanity before us are useful.
Though, one might ask, then why is that when people hear the word
“philosophy” they think of things in metaphysics, esthetics, theology,
epistemology, ethics? The type of questions that seem useless and
never have any answer? I haven't thought of this in detail. I wish to
give a simple, logical reason. Basically, i think it is because when
the thinking and questioning developed certain effective methods on
particular type of questions, they got new names such as all the
branches of sciences, including mathematics, logic, psychology,
linguistics, political science, music, arts, law, cosmology. So,
what's left that are not given new names are the kinda questions we
associate with the word philosophy.
So, for example, if in 20 years, symbolic logic and theories in formal
languages have advanced so far that we are able to classify all our
computer langs such as lisp, perl, OCaml, C, in some precise way with
formal (symbolic) definition on “practicality”, “beauty”, “power”,
then, our “philosophy of computer languages” will cease to be such,
instead, it'd be a new name, new science, where we use systematic
methods to persuit the question of “best language”, instead of the
lose words and written thoughts. But still, as human animals, we will
probably still debate and discuss the beauty of languages in
traditional way of words and opinions, just as we like poetry, so
there is our philosophy again — eternally connected with something
seemingly useless and impractical.
Xah ∑ http://xahlee.org/ ☄
I think philosophy is a property of a certain density of computational
power, (otherwise known as intellect) in a life form and likely
emergent behavior built from other skills like language, opposable
thumbs, and whatnot the life form posesses. I believe that humans
_may_ be the only thing which posses enough intellectual density to
exhibit it on this world.
However, the ability to perform philosophy is not just _any_ characteristic.
It is the characteristic which causes profound changes in how a society works.
Groups of people organize according to common philosophical points of
view. Economic philosophies are one of them. Capitalism, Communism,
etc, etc, etc.
A philosophical question as simple as "Are my mind and body
separate?" has spawned religions which have encircled the globe and
affect many people's daily actions at a measurable level.
The seed of philosophy is observation, the medium of philosophy is
language, the effect of philosophy is change.

You're talking about "philosophy" in the large, the way a Ph.D. in any
subject area is labelled a "doctor of philosophy", or the way philosophy
was explored thousands of years ago.
The problem is, in the modern world all the good parts got cut away and
given their own disciplines. Most of the valuable work that you're
talking about is now called "mathematics" or "physics" or "astronomy".
The criticisms are about what remains, in modern college Departments of
Philosophy. When a professor applies to a tenure-track position, what
determines whether they will apply to the college physics department, or
the college philosophy department?
It's the people who work on philosophy today, as well as the thousands
of years tradition of exploring those same questions from the past, that
is being criticized here.
Not the general idea of "critical thinking", which indeed was part of
the original tradition of philosophy, and indeed is still valuable today.

In essense, yes. Otherwise it's in the category of a hobby, for
personal amusement. Perhaps I like to collect painted figurines, or
play Call of Duty on my XBox. But I wouldn't call that a "field of
study" that is worth granting graduate degrees in.

No, the problem is that philosophy doesn't answer those questions
either. Philosophy _addresses_ the questions, and writes volumes of
words about them, but it doesn't _answer_ anything.
The field has no content. It only has history, and an ongoing process.
But it doesn't actually have results.
Really, you need to contrast this with fields that actually do have real
content. I want to build a bridge over a river gorge that will support
the weight of tanker trucks. Civil engineering provides the answers,
and even a training procedure that will result in qualified humans who
can change the world such that the bridge gets built. I want to get a
spaceship to Saturn and take photos of the rings. Again, orbital
mechanics, physics, and electronics get this done, and a few years later
I have my photos.
I'm interested in the questions that philosophy explores. I want to
know, in what cases is it "right" for the minority to win over the
majority? Do humans have free will? The questions very much interest
me. But what are the answers? I look to philosophy ... and find no
answers. To any questions.

I agree, that the worst of mathematics, is like all of philosophy.
But even in math, there is at least a field of study out there, which
exists independently of any humans. Math theorems are discovered; the
real truth is already out there, and a given mathematician is either
capable of finding them, or not. It doesn't matter how socially
esteemed a senior mathematician might be; the most humble new math
student can instantly overshadow them, if the student discovers the true
theorem, and the venerated professor makes an error.
This is because math actually has an external field to study. There is
actually a right and a wrong to claims, and eventually the truth can
become clear to all.
Philosophy doesn't have any way to make judgements. So instead it's a
social game, about pecking order and prestige and publications. It's
not actually about the work itself.

There is value in thinking clearly, yes. But philosophy doesn't even
have a monopoly on this. There isn't a sequence of courses taught by
the philosophy departments in "generic critical thinking" or
"rationality", which are taken by students of physics and economics and
biology, where the students who have passed the courses actually do well
in their own disciplines, but the students who have not yet taken the
courses constantly make reasoning errors and fail to progress in their
own disciplines. This just doesn't happen.
In fact, the closest to this are courses like Probability or Statistics,
which do indeed cover methods of rationality that are often
counterintuitive. Surprisingly (to you?), these courses are generally
offered by the departments of Statistics or Mathematics, not by the
department of Philosophy.
Philosophy _doesn't_even_offer_a_course_of_study_on_thinking_.

In theory, you could. But in practice, this doesn't actually happen.
In practice, ethical philosophy has no content to offer social policy,
and philosophy of mind has no content to offer psychology. (The content
you imagine being offered to psychology actually comes from computer
science and cognitive science, not from philosophy.)

Instead of having "answers" on a math test, they should just call them
"impressions," and if you got a different "impression," so what, can't we all
be brothers? -- Deep Thoughts, by Jack Handey
An example:
Philosphy asks the question: "Do we have free will?"
100,000 years later, societies rise and fall, we move from nomadic to
agricultural based living which gives us more free time, mathematics
and empirical science (sub-disciplines of philosophy whose purpose is
to answer only "How" something works, not why) arise, and eventually
we build gigantic particle accelerators to empiricaly test quantum
theories and discover the world really *is* random in its base
fundament.
Then these disciplines fall up the stack of the evolution of thought to the
original question and provide the unequivocal answer: "Yes".
That's why philosophy is interesting.
Philosophy is likely best understood like geological time in human thinking.
The history in philosophical thinking is exactly the benefit of it.
I bet you the next question Philosophy will ask is: "Should we care?"

Well we have a potential infinite regress. Applied across the board
everything must be justifiable by being a means to something else. Do
you really mean to say that? Or are you saying that there is
something specific to philosophy which means it must pass this test of
contributing to something else though these other somethings are not

The nub here is that you haven't made clear what you mean by 'useful'

your idea of value is the appropriate one. This is why I asked you to

'value' earlier.

What does 'doesn't actually have results' mean here? It could mean.
1. It produces no results because philosophers never arrive at a
common agreement or knowledge on anything
Actually I don't think that is true. For instance, take this
proposition
"Pure utilitarianism is inconsistent with the idea of unalienable
rights."
Most modern philosophers with any background would agree with that.
This was an insight of the C20 critique of Bentham and Mill. What
philosophers then go on to do is to ask this kind of question.
"Is there any modification of utilitarianism which can support
unalienable rights?"
or
"Can we define what are the unalienable rights? "
The argument continues but has moved on. No philosopher today would
propound utilitarianism in the manner of the early C19.
2. It produces no results because philosophers never arrive at a
settled state. The subject is always in ferment.
True; but the same is true of the sciences. "What are things made
of?" has occupied us in the West for 2,500 years. Every discipline
has its ferment - unless it is dead.

I think you are mistaking the purpose of "generic critical thinking"
and I would recommend Thouless 'Straight and Crooked Thinking' as a
corrective. Normal science, which is what a UG does, is highly
constricted in its methodology. You learn about properties of
materials and numeric algorithms etc. and mainly the goal is to
minimalise personal judgement. There is a body of formulae to apply
and material to learn and you learn it.
Critical thinking courses are not really about improving your scores
on this kind of material. Critical thinking is about improving your
ability to spot holes in people's arguments, face social questions and
to help you evolve into a citizen; not just a competent economic cog.
Critical thinking is the first casualty of any totalitarian state.

I assert that they aren't their own disciplines, but sub-disciplines of
Philosophy created to answer the questions put forth by Philosophy.
Philosophy askes Why, the subdisciplines state How.
As for why the sub-discipline makes the agreement that a PhD candidate

in general making the statements, it is a delegation of knowledge

are no good. Those sets intersect and produce contradiction in your statement.

Sadly, while I might disagree with you on some fronts, this isn't

First of all, you're back to "inconsistent", as the best you apparently
can do. Again, just internal to philosophy, not connected with anything
in the real world.
This is a game, in words, and definitions of words, and logical
consequences. The game is: "Assume the following 10 random things; then
the following 50 theorems are logical consequences of the 10
assumptions." Yes, that might be true. Or perhaps a "brilliant"
philosopher will discover some inconsistency.
But the problem is, the ten assumptions have no connection with the real
world. So nobody outside philosophy ever cares.

Sure, sure. Exactly.
And the college departments of philosophy do not offer training courses
in this content.
There are courses in systemic errors in human reasoning; these are
offered by departments of Psychology or Cognitive Science. All sorts of
typical human bias: anchoring, projection, hindsight bias, confirmation
bias, fundamental attribution error, etc., etc. (Why weren't these
discovered, published, and countered by professional philosophers?
Because they never do experiments. There is no subject matter in the
real world that they are exploring.)
There are courses in drawing the best conclusions from real world data.
These are typically offered by Statistics departments. Bayesian
probability, etc.
There are courses in rhetoric, in the use of language to persuade and
achieve goals. These courses are usually offered by English
departments. Perhaps sometimes Political Science. Debate, journalism,
that sort of thing.
But the Philosophy department ... they mostly define new words to each
other, explore logical consequences, report on their introspective "gut
feeling" on which assumptions seem "reasonable" ... but have almost no
connection to the real world, and thus no impact on it.

How about entertainment value? Lots of people pay for books and classes
in philosophy who have no aspirations of becoming professional
philosophers, just as lots of people go to see plays and movies who have
no aspirations to become actors, or listen to music with no aspirations
to become musicians, or read fiction with no aspiration to become
authors. Actually, an even better example is magic, which has value
precisely because it provides false answers to the question of how the
trick was done.
How about Answers to the Great Questions (e.g. what is the meaning of
life?) Even if the answers that philosophy provides are baseless or
even false, that doesn't mean they don't have value. Indeed, providing
people with baseless or false answers is an enormous industry. It could
even be argued that baseless, false answers might be preferable to no
answers under certain circumstances. (Like, for example, oh, I dunno,
if you should happen to find yourself trapped in a mine for two weeks
with no idea if you will ever see daylight again?)
The utilitarian critique of philosophy is fraught with peril.
rg
The historical accident of their foundation is not really that
important. Yes, Newton called his book "Natural Philosophy". Yes, once
thousands of years ago, all this scientific inquiry was done by
"philosophers".
The point is that, today, the college departments of Philosophy have no
connection with the other sciences. The departments of Physics,
Chemistry, Biology, Economics, Cognitive Science ... none of these
people make pilgrimages to the Philosophy department, to learn what new
things they've discovered, and to help their own "sub-discipline" work.
Philosophy "launched" these "sub-disciplines", but then lost all contact
with them. They're self-supporting now.

I was attempting to refer to the questions that modern philosophers ask
today, the kinds of topics which are published in their journals. These
are often not new questions; they were originally explored by the
ancient philosophers thousands of years ago.
It is the parts in _common_, between ancient and modern philosophers,
which have very little value.
Ancient philosophers explored many other topics, besides those which
continue to concern modern philosophers. Some of those topics had
value, and have since peeled off into disciplines with new names.
The parts that remain in philosophy, a subset of ancient philosophy, are
the most useless, unproductive, navel-gazing parts.

Really? What does Ghana spend its time on? How about China? Don't you

interesting predictions to make about the future of those societies,
than Philosophy does?

You're giving philosophy too much benefit of the doubt. You ought to
consider the horrifying possibility that they NEVER tie together all the
"sub-fields" (physics, biology, psychology) into any kind of a "whole".

That's exactly the problem. The kind of story you just told, is the

This indicates your assumptions. You are subscribing to a very
particular school of philosophy, which involves utility/exploitation,
and are defending and advancing that school by attacking and
discrediting the field in general. The politics behind your tactics
works because then there is no basis to question your assumptions.

ps. How the Hell did you get out of my killfile?
Let's explore this. You claim that I've misunderstood quantum mechanics
(likely) and due to this the universe is deterministic (unlinkely).
Then, we're done. Bam. Universe is Determinstic and no free will. I
can build a measurement device to perfectly measure you as a human
being and the locality in which you exist, and then compute the field
equations of your future with perfect accuracy.
Sadly, the Copenhagen Interpretation, in which the actual choice of
the collapse of the wavefunction is unknown at collapse time, and
the de Broglie???Bohm theory, in which a guiding wave function (that
describes the whole of the universe's configuration, aka, the hidden
variables but we don't even know what they are and the wave function
does not collapse ever), are both equivalent in what they derive and
in accordance to emperical theory. The first is non-deterministic,
the second is deterministic. There are others besides those two,
and they disagree on determinism, on, as far as I can tell, based
upon if there is a universal wave function or not.
In mathematics, this is a contradiction. So maybe the problem is "Do we
have free will?" is not a valid question, and the true answer is "mu".
The would get a bunch of people's panties in a bunch, I tell you!

If there is randomness, then there is never a true prediction of the
choice a person made. That readily equates to free will.

I will admit there is no overwhelming consensus. But most later
theories for quantum mechanics are non-determinstic. If empirical
evidence shows that to be correct and the universal wave function
falls to the side as uneeded, it is inevitable that the answer is
"Yes". It becomes an axiom of the universe, like a physical constant.

This is not obvious. For example, computers live in the same universe
as us, however, they don't demonstrate free-will. In general both the
hardware and the software is made so that their choices are
deterministic.
And even if some choices were made randomly (based on a real random
physical process) that wouldn't mean these systems would have free-will.
To begin with you would have to define what it is to have free-will.
My own definition, is that the Creator (or anybody else) doesn't
override the choices made naturally by the creature. Notice that this
definition is orthogonal to determinism or randomness. In the case of
computers, a program has free-will(pjb definition) as long as the
programmer doesn't change its state (eg. with a debugger).
--
__Pascal Bourguignon__ http://www.informatimago.com/
Now we come down to whether or not we can enumerate all possible
choices a system can make or not. You implicitly state that knowing the
complete "information function" of a system renders it deterministic
and therefore is lacking free-will. This is the same argument as the
de Broglie-Bohm interpretation of causality. *You* are the universal
wave function in which the computer's world-line is a subset.

[Joke: I am disturbed by how thin a difference there appears to be
between a bug and free will. :)]
I would make the definition of free-will that requires there to be
exactly zero chance of deviation from a deterministic evolution of
the function describing a change of state in the system. That would
include no debuggers. :)
The consequence of my statement is this:
A high energy photon flips a random bit in the memory of a computer
causing it to make a choice it was otherwise unable to make through
formal verification of the algorithm. Now, suppose at each mutation of
the memory space by the code from the previous mutated state, another
photon comes and forces yet another deviation from the evolution
predicted by the text segment's instructions.
However improbable, but not *impossible*, different photons strike
the memory again and again to alter the behavior of the program so
that it simulates the information processing algorithm of the human
brain. It achieves identical "sentience" as long as the photons
are changing the processing of the computer at each evolution of the
program. When the photons stop striking the system, it immediately
becomes determinable.
I don't claim that this has ever happened. :)
Free-will, to me, is simply that it is actually impossible to determine
the system's future. In my definition, metal, stars, people, etc,
etc, etc, all have free-will.
Strange, no?

(Sigh.) Yeah, I figured you wouldn't let that go. I'm reluctant to go
much further, as this takes the thread in a whole new direction, even
farther from the purpose of this actual newsgroup as the original topic.
But ok. I'll try one brief one.
> You claim that I've misunderstood quantum mechanics (likely) and due
> to this the universe is deterministic (unlinkely).
Quantum Mechanics is one of the best-tested empirical theories of all
time. It's as "true" as science ever gets. However, there is no
randomness at all in the equations of quantum mechanics. There's a
waveform, but there is never a "collapse". That's simply not a part of
the theory of QM. (Well, ok: the Born probabilities bridge the two
worlds, yes.)
On top of QM, there are _lots_ of "interpretations" about what the
equations "mean". Some of these are deterministic, some have
randomness. The interpretations are not particularly well-supported,
and it's a mistake to take the empirical conformation of QM as evidence
about any particular interpretation.
> Then, we're done. Bam. Universe is Determinstic and no free will.
Doesn't work that way either. This is why I asked you for the detailed
argument of how you get from randomness to free will. (Hint: you really
ought to try to define what you even mean by "free will" first, before
asking whether any particular entity has it.)
In any case, I happen to believe that free will and determinism are
compatible. (Alas, there is not enough space in the margin to
explain...) I certainly will not grant you a "Bam. We're done." on
this question.

That does not follow, actually. But there are ways besides randomness

I doubt I would have written those words, but it seems at least that you
already understand that quantum mechanics does not necessarily imply
fundamental randomness.

1. Hardly anyone uses the phrase "free will" to mean "random behavior".
They mean that they are in control of their own actions. (Vs., usually,
being a puppet of some kind, where some other entity or influence
controls them.) Randomness is the opposite of control.
2. Your simple argument from (wrong) physics doesn't seem unique to
humans. It seems to apply equally well to chimps, or birds, or even
rocks and stars. Do they all have "free will" too?

Truth is not a popularity vote.
In any case, you need to distinguish QM theories (which have empirical
support) from interpretations (which mostly don't).

I'm amused that your best example of a result from philosophy on a
long-standing question, seems not to have consensus from within the
field itself (by your own admission).

For a process, there's no difference between the presence or the absence
of a bug. It only behaves according to its program whatever that may
be. That's what free-will is for the process. A debugger allows an
external entity to modify the state of the process thus depriving from
its free-will. But you can do that independently from the presence or
absence of a bug. You can actually _inject_ bugs with a debugger, to
see how well the program recovers from them. But you could also have
the process do something that it would never do by its own free-will
(by it's own program, bugs included).

In microprocessors and memories, there's protections against these
improbable events. And I'm sure Intel tries very hard to protect us
against "bit flipping" when they reduce the number of electrons required
to denote 0 or 1.
In human brains, it would be harder I guess to have a neuron fire
(against its will) from random subatomic events. But I guess if it
occured, it could be qualified as a privation of free-will, depending on
the exact neuron activated and the consequences it would have.

This, would be IMO, the reason why God gives us free-will. He wants to
know what will happen. If He messed with us, the experiment would
become useless.
I respect your argument, but I find I don't want to continue in this thread.
It is obvious that I will, in fact, not be reconciling 20 thousand
years of philosophical questions with respect to existence and current
events. Don't worry, bridges fall down and cancer still happens. So
the sub-disciplines that philosophy generated get a couple whacks

I find that interesting. Can you give me a few references to papers
from philosophers who wrote on this topic?
We generally have a really hard time predicting what people do -- see
eg the literature about time-use survey data (such as the ATUS, the
American Time Use Survey). I was not aware of philosophers working on
models with quantitative predictions about this, in fact, I find that
surprising.

> The utilitarian critique of philosophy is fraught with peril.

Isn't everything?
I have read such histories, so if you have a specific comment, perhaps
you should make it.
Perhaps an example will better explain the contrast. Consider Grigori
Perelman, the (now) famous and reclusive Russian mathematician who
proved the Poincare conjecture, "one of the most important and difficult
open problems in topology", a century after it was first posed:
http://en.wikipedia.org/wiki/Grigori_Perelman
He never talks to anybody, never gives interviews. While he has worked
in academia in the past, he no longer holds any academic position, and
appears to be unemployed. After proving Poincare, he withdrew
completely from working on mathematics, even in private. He was offered
a $1 million award for the Poincare proof ... and he turned it down. In
his rejection, he said, "the main reason is my disagreement with the
organized mathematical community. I don't like their decisions, I
consider them unjust."
Perelman is a social outcast. He rejects the entire status game of his
community. Yet, despite his refusal to play by any of the rules, he's
held up as one of the best mathematicians of the last century. The
field that he despises constantly tries to give him awards.
Now. Contrast that with philosophy. Can you find a similar example?
Can you find a philosopher who hates all the other professional
philosophers, who disrespects them every chance he gets, refuses to
participate in tenure or publication ... but who nonetheless is hailed
by the very community he despises, as one of the best philosophers of
his generation?
No. And the difference is, mathematics is a discipline that is actually
about something. The difference is, Perelman actually found a proof of
Poincare. It doesn't matter how rude he is; he found that proof, a
century of other mathematicians tried and failed to find it, and even
mediocre professional mathematicans can _verify_ that Perelman's proof
is correct (even though they couldn't find it themselves).
Philosophy has none of that. There is no actual subject matter being
studied. There is no result that an anti-social philosopher could
write, which would overcome his rejection of status games, refusal to
participate in conferences, lack of publication in journals, etc.

Ah! So you have, in fact, been doing typical philosophy yourself,
during this whole thread. People for thousands of years have had a
question, "do humans have free will?" And they meant something by this
question.
You, as is typical with philosophers, confidently "answered" the
question ("yes, because of quantum randomness"). But the truth is, all
you really did was redefine the term "free will". You used the same
term as everybody else has been using, but you were using your own
private definition, which didn't at all match the concept that everybody
else cared about. And, in a typical bit of philosophical subterfuge,
you didn't bother to explain your redefinition when you first made your
bold claims.
What a perfect example of philosophy. Lurkers on this thread don't even

of the process by yourself! Philosophy is about words and definitions

Are you sure? Have you asked any philosophers? And even if it were
true, why is that a problem? It so happens that you can't do magic
without knowing how the trick is done, but that's just a characteristic
particular to the art of magic. There are other arts whose
practitioners would have a very hard time explaining "the trick", like
writing poetry for example. Even writing computer software is a craft
that seems to be somewhat resistant to deconstruction. None of this
changes the fact that writing computer software has value, as does
writing poetry. So why not philosophy?

Are you sure that those assumptions really have no connection with the

Let me remind you that if the world is essentially non-deterministic
there's no sense on spending large amounts of money on sciences.
Not only on LHC, but also on GARP or NARE (see Atlantic Tropical Experiment,

Huh?
Pretend that the outcome of a coin flip is non-deterministic. That just
means, for a single flip, we can't predict whether it will come up heads
or tails.
But you get science by noticing that, over the course of thousands of
coin flips, pretty close to 50% of them come up heads, and 50% tails.
That's the situation here. The non-determinism in physics (if it
exists) happens at very tiny scales. Pretty much any phenomena of
interest is composed of trillions of these basic actions, so you can "do
science" in a "non-deterministic" world, simply by predicting
statistical averages.

I got the impression that at the quantum level things were not that
deterministic, that there was some essential randomness. (Not only
randomness due to lack of information).
Then we have some macroscopic scale where randomness is averaged and you
can compute the temperature and pression of a sizeable volume of gaz in
a deterministic way.
But then on an ever bigger macroscopic scale, you get human beings, and
appearently, non determininstic behavior.
But then you've got societies of human beings and you get some
deterministic behavior, and if some randomness remains, probably we have
here chaotic behavior.
And just go up one level, and the behavior of the planet, the solar
system and the galaxy is deterministic, unless you watch it at a longer
time scale in which case it's then chaotic.
So it seems to be that determinism, chaos and randomness may occur at
different scales for different systems, and that you can sometimes
render a system deterministic (eg. by constraining it, or by changing
its scale), and you can also render it chaotic or random again, by
increasing its complexity up a level (and sometimes, you don't even need
a lot of added complexity to get the change of phase).
I'm out of this thread, but North Korea is a good example of a
whole society acting with the philosophy (Juche, if I recall) of the
rulers. It is probably the best example we have.

Just to be clear, the cases are:
1. Deterministic (= predictable in theory), and predictable (in
practice)
2. Deterministic (in theory), but not in practice (aka "chaos")
3. Non-deterministic (in theory, and thus in practice as well)
Once a system goes to one of the deterministic cases, it doesn't really
ever go back to non-deterministic at higher levels of scale. It might
go back to chaotic, but that's about it.
To get back to the original point, physics being non-deterministic at
the lowest level (which may or may not be true), doesn't really affect
whether humans are predictable (in practice) or not. At the scale of
humans, it's really a question of chaos vs. predictability, not a
question of non-determinism.

Well I think you do need to be precise. Neither of these definitions
would do the job you seem to want it to do. They are of course non-
equivalent. Marxism has had a huge impact on society. Buddhism is as
much a philosophy as a religion and that has had an enormous impact
too. So by your first criterion, philosophy is very useful.
Your second criterion 'something people would pay for'; people do pay
to
attend courses on philosophy and read books on it, so presumably it is
useful by your second criterion too.
Some philosophical thinking to be done ;).

Thanks. I have skimmed through those articles, and I don't really see
the predictions being better supported or more precise than a
reasonably good sci-fi book. So yes, these things make an interesting
read, but I see no attempt at doing anything remotely quantitative;
consequently, the claims are hard to evaluate.
For example, starting on page 10 of the first article, he speculates
about the extinction of humanity, but all the numbers he uses seem to
be pulled out of thin air. He cites other people (mostly
philosophers), and quotes their numbers too, but makes no attempt at
reconciling or explaining the differences between them. I get the
impression that if I became a philosopher with tenure at a decent
university and wrote about this topic, my numbers would be cited in
articles like this -- even if I just made them up. I find that
disturbing (to be fair, similar things happen in the natural and
social sciences to a certain extent).
I see little value in statements like "Nanotechnology will have
wide-ranging consequences for manufacturing, medicine, and computing."
(p17). Certainly true, but also quite trite in 2007, 12 years (!)
after Neal Stephenson wrote The Diamond Age.
Please don't get the impression that I am trying to dismiss the work
of all of those who call themselves philosophers. I have read some
good books from people who are employed at departments of philosophy,
eg on religion (by Dennett) or the history of science.

I was thinking of emergent properties, which may be possibly random.
But perhaps real randomness in emergent properties can only be
reintroduced by use of real physical randomness with a lowleveler device?

Or the influence of physical non-determinism on the human behavior, or
the question of the soul (an entity external from the physical universe,
influencing it), which cannot be discarded, so far.

Past performance isn't necessarily indicative of future performance. As
you said, it took 100 years for Perelman to prove Poincaire. Yes,
philosophy has been around longer than that, but:
1) philosophy spins off new disciplines which detach themselves from
the root, and
2) the problems of philosophy may be much harder than Poincaire or
Fermat. Just as one example, in the never-ending discussions on free
will, nobody can ever agree on a definition. Why?

The answer to both questions depend on the nature of reality. If there
is a God, you get one answer. If there are gods, you get another. And
if there is no god, you get yet another. Philosophy is like geometry --
the axioms control the reality. Whether the mental construct
corresponds with the external physical world we call "reality" is yet
another question.
Mathematical definition presupose a known structure.
It's just giving a name to some mathematical constructs that already has
a meaning (the first thing you do once you've made a definition, is to
check that it has a meaning, that you have effectively named a known
mathematical structure). You may not know all the properties of that
mathematical structure, but nonetheless, it exists within the frame of
the theory you're working in.
Outside of mathematics, we try to name things, but unfortunately, they're
not in general inside a known theory, but outside, in the real world.
So our definitions are in general entirely inadequate to denote what we
want to denote.
The reason why two philosophers will give different definitions, and in
general not agree they're the same, is because they give them with a
preconceived theory.
This is not necessarily bad, we have the free-will element of the
quantum-mechanic universe, the free-will element of the universe as a
computer program run by God, or any other kind of free-will elements in
other theories, like we have the neutral element of (ℝ,+) and the
neutral element of (Z,×), and they're two entirely different
mathematical beings, but still both are neutral elements. Remains to
be seen how these theories match reality.
If you haven't recognized it yet, invariably Geddis' debating tactics on
CLL are a perverse variation of the diagnolization argument; this
involves subscribing and appealing to a particular set of (unstated,
restated, shifting) assumptions which are then used to contradict
opposing views.

Because they're not actually discussing a topic in objective reality.
All they have is internal gut feelings and poorly-understood
introspection. (Which they put far too much stock in. Ever notice how
few philosophers ever question the reliability of their own
introspection?)
So they wind up playing games with language and words and definitions.
But the ACTUAL problem of free will, in the REAL external world, is one
that has a solution. If you're ACTUALLY interested in the real question
of whether humans (or any other entity) has free will, there do exist
real answers. For example, Eliezer Yudkowsky has given an explanation
in detail. The background starts here:
http://wiki.lesswrong.com/wiki/Free_will
The solution series of posts is here:
http://wiki.lesswrong.com/wiki/Free_will_(solution)
If you're interested, but not willing to read all that background, the
critical post is probably this (long) one:
http://lesswrong.com/lw/rb/possibility_and_couldness/
And the answer, for those who don't have the patience for any long
posts, is basically that the internal human feeling of "free will" is
not an illusion, and does correspond to a real property about real
machines. In particular, about machines that have decision procedures
that explore possible future worlds, and use their evaluation of those
future worlds to choose a current action.
Free will is: "I can do whatever I want". Which can be made precise.
And is not incompatible with determinism (whether or not physics really
is deterministic), because, as Schoperhauer said, "Man can indeed do
what he wants, but he cannot control what it is that he wants."
So. There's your answer. And I know you'll be quick to say, "but
Yudkowsky was doing philosophy there!" Sure he was. But he was not a
professional philosopher, he never took philosophy classes, and the
thousands of years of "work" in philosophy never informed his own work
(except as an example of what not to do). His work will never be
published in a philosophy journal. Because it isn't the game with words
that philosophers play; it's about the real world instead.
Yudkowsky is a computer scientist. His insights came from his work in
CS, and in particular his work on AI. Computer Science an actual
science, where results come and build on each other. That's why he
could solve free will so easily, a problem that has vexed professional
philosophers for thousands of years.

You two really seem obsessed with that free will question (bringing it

not sure at all who of you is the one with the stronger religious

That's an interesting position, but based on the conversations I've had
regarding this, I think that's not a fair characterization. I think
they are interested, but other things come into play:
1) What is "objective reality"? For example, does God objectively
exist, or not?
2) The way our brains are programmed (which we've only begun to
explore) makes it hard to settle on an answer.

Gosh. I applied this same kind of methodology to the question of
morality and came up with a similar explanation of good and evil
(cf. http://stablecross.com/files/Eden.html -- the three introductory
links give the background information). What I found interesting is
that the solution to the problem was suggested by John McCarthy (see --
I'd tie this in with Lisp, somehow) from a 1960 paper of his. When I
get some time, I'll finish writing up how to dismantle Hume's
guillotine.

Is it? First, how do you know that man cannot control what is is that
he wants? If that's true, then Hume is right and ought does not follow
from is. Second, we have to deal with conflicting wants all the time.
At the moment, I very much want to do something that I don't want to do.
I've been struggling with it for at least a week. Do I have control
over which one I will end up doing? What is the mechanism by which I
will decide? Will it be by application of reason? Will it be the
inputs to my neural net eventually resolving the stalemate one way or
another? If so, what control do I have over that?
Second, that's not the interesting issue, anyway. In an atheistic
universe, why should anyone care about this issue? Free will is really
only an issue if there are 1) ultimate goals and 2) some kind of penalty
for failing to reach those goals.

The "real world" needs marketing. It isn't just the discussion of
ideas; it's the dissemination of those ideas through the population so
that they can inform future work. I've solved the problem of good and
evil; fat lot of good it does if nobody reads my blog.

I guess I don't make the same distinction between philosophy and other
disciplines that you do. I've toyed with finding the time and money to
pursue some advanced degrees, but I don't know whether I want to get a
masters in CS or theology first. And, frankly, I dont know that there's
a whole lot of difference between the two.
Like I said, CS is a young field. I suspect it's going to start uniting
things that had formerly been considered separate disciplines.

Sorry, I thought you just brought up "free will" as a mere example, but
I didn't realize you were directly interested in it on its own. As it
turns out, I happened to provide pointers to the answer anyway. I

I've been trying to distinguish between:
1. People who call _themselves_ "philosophers", who get employed by
Philosophy departments at universities, who publish articles in journals
devoted to "Philosophy", etc; vs.:
2. Careful, critical thinking (in any discipline).
The latter has value, surely. I think it's a mistake to label it
"philosophy", as that becomes so broad that it's hard to say much about
it.
My criticisms have been solely about people in category #1 (for the last
few centuries, anyway).

Daniel Dennett calls himself a philosopher, was at one time employed by
a philosophy department (they changed the label to "cognitive science"
because that's more fashionable nowadays), publishes books that appear
in bookstores categorized as philosophy. But I would say that Dennett
is a pretty clear, critical thinker. Likewise for Bertrand Russell.

Not according to Bertrand Russell. In "The Problems of Philosophy", he
wrote:
"In one sense it must be admitted that we can never prove the existence
of things other than ourselves and our experiences. No logical absurdity
results from the hypothesis that the world consists of myself and my
thoughts and feelings and sensations, and that everything else is mere
fancy." (pg. 23).
> That is objective reality.
If it exists only in my (or your) mind, just how objective is it?
Objective means "independent of mind".

Yet we take such predictability as an article of faith. Russell
discusses this here: http://www.ditext.com/russell/rus6.html
In part, he writes:
"It must be conceded, to begin with, that the fact that two things have
been found often together and never apart does not, by itself, suffice
to prove demonstratively that they will be found together in the next
case we examine. The most we can hope is that the oftener things are
found together, the more probable becomes that they will be found
together another time, and that, if they have been found together often
enough, the probability will amount almost to certainty. It can never
quite reach certainty, because we know that in spite of frequent
repetitions there sometimes is a failure at the last, as in the case of
the chicken whose neck is wrung. Thus probability is all we ought to
seek."

Beg pardon? The issue of free will absolutely hinges on whether or not
God exists. Either He "interferes" with some of our choices or He
doesn't. Pascal has been trying to get this point across from some
time. Calvinists say He does; Arminians say He doesn't. I'm not sure
what Thomists mean.
And, as I said, the notion of free will in a materialistic universe is
really uninteresting -- it doesn't matter whether it's "free" (in
whatever sense that means) or not.

I agree. Daniel Dennett is the best professional philosopher working
today. Of course, he spends most of his time ripping apart the muddled
thinking of all the other philosophers.
He's "the exception that proves the rule", if I may misuse that phrase.
(Everyone else misuses it ... why not me?)
> Likewise for Bertrand Russell.
OK, I'll give you two.

If university Philosophy departments were filled with guys like Dennett
and Russell, "philosophy" would mean something totally different than it
does today.

On the other hand, see "Dennett: the insult comic sophist"
(http://voxday.blogspot.com/2009/02/daniel-dennett-comic-superstar.html)
where person's opinion of Dennett is:
"Anyhow, I don't know why anyone would be surprised that Dennett didn't
respond directly to arguments put forth by an opponent. Avoidance and
evasion are standard New Atheist tactics. And it's obvious to anyone of
sufficient intelligence who has read Dennett's books that he isn't
capable of directly responding to counter-arguments because he's nowhere
nearly so bright as his fans, most of whom don't understand his
arguments, tend to think. Now, it's true that unlike Harris, Hitchens,
and to a lesser extent, Dawkins, Dennett seldom commits openly egregious
howlers, as his story-telling snow jobs are well suited to conceal his
baseless assumptions, naked assertions, factual errors, and outright
logical blunders. This is why TIA featured an entire chapter dedicated
to highlighting Dennett's mistakes, most notably his logically quixotic
attempt to justify a specific division of doxastic labor that he
declares to be otherwise immoral."
Maybe it's time to find a new hero?
This is just a restatement of "brain in a vat".
Whether or not you are a brain in a vat, the point remains that it's
easy to set up situations where you are unable to predict what future
sensations you will experience. And yet you eventually discover that
those future sensations follow a regular, predictable pattern.
It is that pattern of future sensations I'm talking about. They are
independent of your prior introspection. Whatever you believe the
future sensations will be, however much you have convinced yourself that
they will turn out in one way, often you discover that they turn out in
a completely unexpected way (which can only be understood as a pattern,
in hindsight).
This pattern of predictable sensations, which is not amenable to prior
introspection, is "objective reality".
Russell is saying that all we can know is that we have sensations, that
they don't need to correspond with anything at all "out there". But
that's not quite right. Because the sensations follow patterns which do
not appear to be present in our thoughts and feelings, prior to
receiving them via sensation. So at the very least, there is some
pattern "out there", separate from our own thoughts.

I understand that, for you, the question of free will is all about the
interference of God. You take it as obvious that, if there is no God
(or if God doesn't interfere), then of course humans have free will.
> And, as I said, the notion of free will in a materialistic universe is

This question doesn't appear interesting to you, but it has been of
great interest to many, many others. Hence all the curiosity about
quantum randomness, and whether that provides an "out" for human free
will, in what otherwise appears to be a deterministic universe (which
seems, to many people, to imply no free will).
Your restriction of the question of free will, only to an interfering
God, is not the common conception of the problem.

Uh, no.
You happened to choose one of the most emotionally laden topics, theism
vs. atheism. Dennett was defending the atheist stance, but that's not
the sum total of his work as a philosopher. In fact, it's hardly even
common in his work. He's not usually named along with Harris, Hitchens,
and Dawkins as one of the prominent "New Atheists".
I'm not at all surprised that a committed, believing, theist was
outraged and offended by things Dennett said, and chose to ascribe evil
and incompetence to his opponent. It's very similar to the kind of
outcome you would see in some emotional political debate, say if they
were debating abortion vs. right-to-life.
The passage you quoted is not an objective evaluation of Dennett. As it
turns out, I've actually read some of his work directly myself. And I
made my evaluation of his skills based on reading Dennett's own
publications, not by a second-hand report from one of his opponents.

Actually, if there is no God, I'm still not sure whether or not humans
have free will. It all depends on how much the application of reason
can control the weights in the part of our neural net that decides on
one goal out of many. After all, every one of us has chosen to do
something that goes against reason.

I'm sure. The question is _why_ is it interesting? What possible
difference does it make, except as a mental exercise? Unless someone
can explain the thinking, it seems to me that it is the product of an
increasingly secular society running on the fumes of the past.
[...]
Oh, sure, could well be. It actually doesn't matter that much either
way. Either way, we can call the patterns in our sensations "objective
reality".
Science offers theories of evolution, and theories of earth geology.
These are theories about "objective reality". Put them together, and
they predict that you will never find fossil rabbits in Precambrian rock
samples.
The important point is that your introspective mind has no power over
whether or not your sensations are able to dig up Precambrian rabbits or
not. No matter what you believe, no matter how convinced you are
... you will still be unable to receive the sensation of digging up a
Precambrian rock and finding a fossil rabbit inside.
This is true, whether "reality" is "really" out there, or "just" a
product of some non-introspective portion of your mind. Either way, the
sensations follow rules, and those rules don't include wish fulfillment
from your conscious mind. And often (like in the case of quantum
theory) they include patterns of sensations that the conscious mind
never even imagined.
Either way, we can call this thing-different-from-our-conscious-mind
with the label "objective reality".
Science makes statements about objective reality. Philosophy, far too
often, does not. Instead, it makes statements that only have internal
consistency (at best), but don't actually make any testable claims about
objective reality.

Well, for many people, this influences their perception of ethics and
morals and justice. If a human's behavior is a predictable consequence
of his genetics and environment, if there is no real sense that he
"could have done differently", then what is the justification for
punishing a criminal? It would be like punishing a rock for rolling
downhill.
What is the purpose of the criminal justice system? Is it revenge?
Rehabilitation? Punishment?
For many people, the answers to these questions depend critically on
whether humans have some kind of "free will", in order to be
"responsible" for their own actions.
(I'm not saying that _I'm_ confused by these questions, but merely
trying to answer why even non-theists are interested in the free will
question.)

Again for the benefit of lurkers, this line of thinking is developed in

Well, no, because that's an example of the "sloppy philosophy" that
you've been complaining about. "Objective" means "independent of mind".
By calling that which _appears_ to be external to us and exhibits
certain patterns _objective reality_, you're basically assuming a
conclusion.
When you can offer a testable claim that reality is independent of mind,
then you can use the word "objective". Until then, to be
philosophically honest, it should be just called "reality".

Sure. Man is a goal-seeking organism without a fixed goal. Absent a
fixed goal (or goals), which the idea of God represents, man is left to
muddle along with whatever goal(s) the community can enforce.

Trivially easy. Man is a fundamentally selfish animal: the selfish
individual against the selfish community. If the community thinks that
it's goals are threatened, or thwarted, by an individual then the
community will take action.

Apples and organges. Rocks aren't goal seeking orgamisms, much less
organisms without a fixed goal that live in community with other
variable goal organisms.

Remember, we are organisms with the built-in heuristic "all fixed goals

questioned.

I understand that. But this is just more lousy philosophy. Organisns
can be responsible by communal (or divine) fiat; no freedom necessary.
The problem is that this sets up a dissonance in our neural net; whether
or not that dissonance can be quieted by reason is an interesting
consideration.

If you're not confused, then you've come to your conclusions by engaging
in philosophy. Whether or not it holds up to scrutiny is another
matter.

You, Bob Felts, are the biggest fool that ever walked the earth.
Now, that sentence you just read is part of your reality. There are two
possibilities:
1. That sentence was a product of your mind.
2. That sentence was not a product of your mind.
If #1 is true then you need to go have a long chat with yourself. (I'd
suggest getting psychiatric help, but that doesn't work so good if
you're a solipsist.) If #2 is true, then whatever it was a product of
is, by your own definition, objective reality. Q.E.D.
> Sure. Man is a goal-seeking organism without a fixed goal.
Hogwash. Man has the same fixed goal as any other living thing:
survival and replication.

Hogwash again. Communities evolved because they facilitate survival and
replication.

Three strikes, you're out. Man has evolved instincts of morality and
altruism because they have survival value. Cooperating groups of humans
survive and replicate better than individual humans. (Religion, by the
way, evolved the same way. There is survival value in inventing the
idea of a paternalistic supernatural being watching you all the time in
order to discourage antisocial behavior. Nowadays we have cellphone
cameras, so God may have to look for a new gig.)

[side note, not directly related]
Atheism is a very recent faith (yes, it's a faith, the same as any
religion is a faith, because humans neither can scientifically prove
the existence nor the non existence of God -- simply because the very
definition of God is: a transcendent being, not scientifically
understandable -- if it were, it would automatically finish to be
God...)
Modern science would not be possible without it's fundamentals, quite
all(!) created by religious scientists of the past. And, as a recent
british study showed, still 3/4 of current scientists are *not* strict
atheists...
(I'm aware that the above will hurt many egos, but these are *facts*,
gentlemen.)

Let me remind you what Russell wrote:
"In one sense it must be admitted that we can never prove the existence
of things other than ourselves and our experiences. No logical absurdity
results from the hypothesis that the world consists of myself and my
thoughts and feelings and sensations, and that everything else is mere
fancy." (The Problems of Philosophy, pg. 23).

Really? Where is that written? In your genes? Are you a slave to your

Aside from the "fixed goal" part, how does that differ from what I said?
BTW, you aren't arguing with me when you argue that man has a fixed goal
-- you're arguing with John McCarthy. This is, after all, a Lisp
newsgroup.

It was a swing and a miss because I said that man is fundamentally a
selfish animal? Isn't that what "the prisoner's dilemma" happens to
also say? That _in spite of_ our selfishness, we "evolved"
faux-altruistic behavior?

That's one of those convenient "just so" stories in which some people
find comfort, but the truth is far more bizarre. In any case, you
yourself said you wanted to know, for example, when the majority has the
right to impose its will on the minority. That we can't come to
agreement on this speaks fundamentally to McCarthy's observation that
man is not a "fixed-goal" animal.
I doubt that very much in light of the fact that Bertrand Russell is
dead. And even while he was alive he wasn't right about everything. In
particular:
> "In one sense it must be admitted that we can never prove the existence

Russell was wrong about this. Read Deutsch's "The Fabric of Reality",
Chapter 4.
The mere fact that I can sit here and type "Bob Felts is a complete and
utter moron" disproves Russell. Think about it. If Russell is right
then whatever it is sitting here typing "Bob Felts is a complete and
utter moron" is part of you, Bob. So there are logically only three
possibilities: 1) you are wrong (at least about being a moron), 2)
Russell is wrong, or 3) you are in fact a moron. You decide.

Yes, if I want to continue to be alive, then I have to survive. If my
genes and memes want to continue to exist they must replicate. Those
goals are wired into living things by definition. If they are not, they
cease to be living things.

Because the community's goals have nothing to do with God and everything
to do with survival and replication.

I doubt very much that McCarthy would dispute that at root man's goals
are to survive and replicate, notwithstanding that those goals may spawn
a wide variety of subgoals.

Indeed. So it would be good if you would cease your thinly disguised
religious proseltyzing.

Yes. Because of the "fundamentally" part. Man can certainly be
selfish, but he is not *fundamentally* selfish. (Our genes are
fundamentally selfish, but that is another matter.)

The prisoner's dilemma doesn't "say" anything. The prisoner's dilemma
is a mathematical model of the interaction of two decision-making
entities. It turns out that one of the predictions of this model is
that apparently altruistic behavior can arise naturally under certain
circumstances. The consequence of this is that there is no need to
invoke God or any other supernatural influence to explain altruistic
behavior in humans.

No, I didn't. I think you're confusing me with one of your other
correspndents.

McCarthy wasn't right about everything either. Even in Lisp he gave us
dynamic typing. We're still trying to recover from that blunder.

Looks like a sloppy definition to me. Transcending what, I wonder.
What do you mean by `scientifically understandable'? Certainly people
can and do come up with claims about dieties' effects on the world
(e.g., the efficacy of prayer) and these claims are, in principle,
testable. (Indeed, they have been tested.) A complete, empirically
verified theory of deities is unlikely, but I suspect that a complete
theory describing the behaviour of a hamster is quite unlikely too, so
that doesn't provide a satisfactory separation. Of course, a deity
which doesn't affect the world is indistinguishable from no deity at
all; but since it doesn't affect the world, its existence is, for
practical purposes, irrelevant.
Lack of `scientific understandability' doesn't anyway seem to be a
necessary condition for divinity. The gods of ancient Greece, as
described in mythology, don't seem particularly hard to comprehend for
the most part. I suspect you're referring to the Babel-fish `proof' of
the non-existence of God.
I'm an atheist because I've not heard any coherent and credible
definition of a `god' that's worth believing in. Most of the
definitions I have heard involve some muddle-headed notion of the
`supernatural', which is an obvious non-starter. But the problem is
certainly one of definition; and definition is a prerequisite for faith,
so my atheism is not a matter of faith. Or, the other way around, if my
atheism were a matter of faith, I'd be able to tell you, clearly and
distinctly, what it was that I believed didn't exist; alas, I can't.

Ummm... What has that do so with anything? Scientific results stand on
their own merits, not on those of their discoverers. Isaac Newton
doesn't seem to have been an especially lovely chap, but his work on
mathematics and mechanics is still brilliant. He also believed some
fairly odd things involving alchemy; so it's probably best not to hold
the quaint beliefs of scientists of the past against their results and
theories.
-- [mdw]
You're getting hung up on terminology again, which is the typical
failure of most philosophy.
Recall again how we started down this particular rabbit hole. I was
criticizing philosophy, because most of it just deals with internal
constructions inside minds, where the most that you can say about such a
structure is that it is "consistent" -- and that's not saying very much.
As opposed to science, which makes testable claims about the external
world.
You complained: how do I know there is an external world? Maybe all the
sensations just come from my own mind?
I believe I've now demonstrated the important points:
1. We start with Descartes, and realize that our own (conscious) mind
(at least) exists. Perhaps nothing besides that exists.
2. But then we notice that our sensations follow patterns which are
often a complete surprise to our conscious mind, and which do not
seem affected by the desires of our conscious mind.
3. So we know that "something else" exists, besides our conscious mind,
which is not under the control of our conscious mind.
We seem to agree on this much, yes?
So then, restated, my criticism of philosophy is that it often deals
with things only in the conscious mind (which suffers from various
fantasies and other failures), and usually fails to make any claims
about the "something else" which is not under control of the conscious
mind.
Now, whether you want to call that "something else" by the term
"objective reality", or just "reality", or even "another part of my mind
but not the conscious part", does that really matter? That's just a
matter of the label you use. It doesn't seem to change your
anticipation of any future experiences, based on that label. The
important part is that it is something which exists that is _different_
than your conscious mind.
So don't fall into the usual philosophy trap of getting hung up on what
terms are used. Try to think about what the words are actually
referring to.
You can now escape from this little rabbit hole of a digression, and
return to the question of why philosophy has been so staggeringly
unproductive despite thousands of years of effort.

I wonder what you think you mean by "scientifically prove". Science is
not actually in the business of "proving" anything.
As this is (supposed to be) a Lisp group, let me share with you a quote
from John McCarthy, Lisp's creator:
An atheist doesn't have to be someone who thinks he has a proof
that there can't be a god. He only has to be someone who
believes that the evidence on the God question is at a similar
level to the evidence on the werewolf question.

I have to get home quickly. I think something terrible may have happened
to my Uncle Owen and Aunt Beru.
Actually, the original intent in developing logic (as stated by
Aristoteles) was to have a method for testing the strength of rational
arguments. In achieving this objective, logic was largely successful.
Logic wasn't developed in an attempt to capture every form of human
reasoning, even Aristoteles realized that there were types of
reasoning that couldn't be easly formalized.
Logic was also not developed to automate human thought, despite the
efforts of AI researchers and cognitive psychologists in the first
decades after the invention of computers. Later, it became clear that
producing an argument is substantially more difficult than checking
its validity.
That wasn't a fault of formal logic, but rather of the excessive
expectations that people had put into it. (In fact, you actually need
formal logic to state the P != NP conjecture, which, with Cobham's
thesis, is the main cause of this failure).

It seems to me that modern mathematics is mostly based on formal

This is the fallacy of the false dilemma. There is at least one other
option: you're just a character in a story my mind is creating and
you're playing the role you've been assigned to play.
Now, that may (or may not) be what is |really| going on but Russell is

And water is wet and the sky is blue. The problem is that there are
people who, by willful choice, do not reproduce. It isn't a fixed goal.
Animals have no choice in the matter: one of their fixed goals is to
reproduce; we have a choice: our goals aren't fixed. Which is what I
said.

You missed the point. Regardless of whether or not God exists, I said
that the |idea| of God represents one or more ultimate (and therefore,
fixed) goals.
McCarthy's insight was that a human level AI would have to meet several
requirements, one of which is: "All aspects of behavior except the most
routine should be improvable. In particular, the improving mechanism
should be improvable."
If something is improveable, it isn't what it ought to be. So, on the
one hand, our wetware says "this isn't what it ought to be. It can be
made 'better'". On the other hand, our wetware has to eventually decide
on something, i.e. "it's good enough." Something has to turn off the
algorithm that says "improve!" Reason says that's a set of one or more
ultimate goals -- however they are represented.

Then why did you write:

below?
"Apparently altruistic"? "Certain circumstances"?
Too, having raised three children, I didn't have to teach them how to be
selfish. The exact opposite was true.

That is what I've been trying to do. (You know, when I first wrote "Bob

No, that is not another option. That is the conjunction of option 1 and
3. If I am a character your mind is creating, and I say you are an
idiot, then either you are wrong (because by assumption I *am* you), or
you are right and you are, in fact, an idiot.

There are people who by willful choice do not reproduce individually. I
am such a person. But that does not mean that survival and replication
are not among my fixed goals. I still participate as part of a society
that maintains an infrastructure that enables the survival and
replication of other humans that share the vast majority of my genes.
Every now and then due to random variation a person might be born who
really does lack the goal to survive and reproduce. Such people tend
not to survive and reproduce, which is why they are exceedingly rare.

Yes it is. It just spawns complex sub-goals.

Among many insect species, notably honey bees and ants, the workers are
all sterile. They also commit suicide when they sting in defense of the
hive. How do you account for this?

McCarthy is a scientist. Among scientists, the fact that survival and
replication are the ultimate goals of all living things is so well
accepted that to state it explicitly is considered pedantic and
redundant. The reason, as you say, that our "wetware has to eventually
decide on something" is that a brain that continually contemplates its
navel and never translates thought into action will fail to survive and
reproduce.
Throwing "God" or even "the idea of God" into the mix is pure sophistry.
The term "God" (especially with a capital G) is laden with baggage. Why
God? Why not gods? Or engrams and thetans? Bringing the conversation
back to the original topic, this is exactly why philosophy and
philosophers are (mostly) useless, because they don't even know how to
properly use words to make progress.

When your goal in dealing with those incorrect arguments is to bring
people to God then you're proseletyzing.

Uh, because it's true?

Yes. (Are you trying to make a point here?) If you want the details
read Robert Axelrod's "The evolution of cooperation." (But of course
you won't because you're not actually interested in learning anything
new. You think you have it all figured out already because you've found
God. You're wrong.)

You did not have to teach your kids not to be selfish. They would have
figured it out for themselves soon enough.

I'm not a solipsist, but I understand how the argument goes. Russell
was right because the argument is right. It doesn't matter who makes
it; the figment or the one with the imagination.
OK, if you really think this to be true, then there is no real
difference between science and fantasy... (and why oh why am I not
surprised by that fact? current science and current fantasy don't
really differ anymore...)
Transcending *my* *own* *intelligence*, *your* *own* *intelligence*.
Then, define "sloppy". This is the most clean (read: simple &
concrete) definition possible.
This is a programming news group. We all here know the difference
between *theory* (read: phantasy) and *practice*, don't we??
That doesn't follow at all. Just because you can't imagine any other
alternative, doesn't mean that there aren't any.
Science establishes likelihoods. What is the chance that one
description of the world is true, vs. another? Even without absolute
proof, there's a big difference between one theory being 99% likely,
while another is only 1% likely.
Also, science regularly _dis_proves theories. You can make a testable
assertion about the world, and then run an experiment and find out that
your claim is false.
There are more possibilities than just your ideas of either absolute
proof, or else complete fantasy.

Mankind. Basically, it's made up of two separate words---"mank" and "ind".
What do these words mean? It's a mystery, and that's why so is mankind.

Terminology is all we have. If we can't agree on definitions then we
can't communicate precisely, and if we can't communicate precisely it
makes it difficult to get ideas across. I spent part of the week at
work recasting external customer requirements into another form to give
back to the customer to say "this is what we understand your
requirements to mean. Is this a faithful restatement of what you want?"

That says an awful lot. Non-euclidean geometry is a construction inside
minds; which geometry corresponds to external reality is still an open
question.

Yes. The problem is that we know that our conscious mind is only a part
of our mind. The part that we are not conscious of may be creating
those patterns, one of which is the solipsists conscious mind.

Even if so, that's a big territory to cover. Sometimes you have to
think about things before you can figure out how to test them -- or even
if they can be tested. Good grief, Don, multiworld is /philosophy/ --
it isn't science. Not yet, if ever.

I happen to think so. Just as differnent mental constructs of geometry
produce different "realities", different philosophical constructs
produce different mental maps.
We still don't know what that external reality really is. We may never
know, but we do ourselves a disservice when we cut off things to look
for.

I know what the words are referring to. But that doesn't help when
talking with other people who might not be familiar with the different
mental map.

That's like saying NASA has been staggeringly unproductive since it's
2010 and life is nothing like Kubrick's 2001. It's a big frontier. And
there have been a lot of spin-offs. Personally, I think the union of
computer science and philosophy will have some interesting results.
