Why yes, of course. In fact, I had a friendly chat with my quicksort

No. Nobody's really working on it. There are four different camps in AI
today, and none of them is actually going to achieve AI:

* The connectionists, aka the cargo-culters - "if we just tweak the
back-propogation, it'll start thinking!" These people have put no real
thought into a definition of intelligence, other than to characterize
it as associative and fuzzy (how we're supposed to do that on a
discrete computer, I can't fathom).
* The logicians, whose hobby is attaching wings to pigs in the hope
that they will fly. These people presume that intelligence is just a
matter of logical deduction, and that logic is the right level on which
to describe how intelligence operates. They have all the high-level
philosophical problems of AI defined and solved, but so far their
computers have not locked them outside in Jupiter orbit, leading some
to migrate to the third camp...
* The Searlites, who believe it can't be done but are still publishing
papers for God-knows-what-reason.
* And finally, there's the people doing stuff that isn't AI, namely
anything that's a domain-specific system or isn't designed to produce
domain-general intelligence. This includes the evolutionary and genetic
algorithms people, the constraint solvers, and probably anything else
that doesn't fit in categories 1-3 (and a lot of stuff that does too;
the connectionists seem awfully fond of making a neural net that does X
and only X and then publishing a paper that says "neural nets can do
X!"). There is a lot of interesting stuff in this category, but they
should go find their own field. If your program can solve a problem
reliably much better than a human can, it's not because it's smart,
it's because you've written a better domain-specific algorithm than our
own general-purpose reasoning, and it's a big clue that you're not
doing AI at all.

Spread throughout all of these camps are the semiotics people and their
deconstructivist / postmodernist associates, who are busy destroying
real intelligence in humans via the educational system.

There, that should offend just about everybody.

If you want to know why AI is not getting anywhere, read Feynman's
famous address on Cargo Cult Science (
http://www.physics.brocku.ca/etc/cargo_cult_science.html ) and compare
to the state of the field. No wonder!

Is AI science? It isn't like experimenters in the field have to discover
how some external phenomenon works, unless it's your connectionists
answering "how many neurons to achieve critical mass?" If the field is
more about groping toward algorithms that exhibit intelligent behaviour,
albeit using a different mechanism than biological organisms do, it's
more like mathematics. And if that's so, the cargo cult analogy breaks
down.

You've discounted superior performance in a particular domain, and you
seem to be setting the bar quite high elsewhere. So what do you
consider AI? Victory in the Turing test or bust? If it's defined as what
humans consider intelligent behaviour, the goalposts are likely to
recede as fast as our computers can advance, simply because the layman's
perception of intelligence is any behaviour that machines don't exhibit.

If computers can already drive cars, play chess and accidentally fill up
their hard drives* while downloading (uploading?) porn on Mars, what do
you want next? It seems that discounting domain specific successes is a
tricky way of saying "if it's solved, it isn't AI."

From what I've heard, electronic games' non-player characters seem to
be improving year after year. That's an area where there's a somewhat
independent arbiter (game reviewers) and an incentive for improvement
(sales). It isn't world changing technology, but it's a plausible Turing
test.

Being in the fourth camp, doing advanced information processing or
other useful stuff, doesn't really mean that you're not in one of the
three first as well. It's perfectly possibly to work on (say) advanced
search by day, and igor-tinkering with the cargo cult by night.

I would extend the cargo cult phenomenon beyond "just science". I've
seen entirely too much cargo cult programming - putting together parts
of programs without any real understanding of what's going on. When
you're helping a student who has close parens and open parens littered
randomly throughout their Scheme source, it's pretty obvious that the
student is not reasoning about how Scheme works, but putting together a
program that has an appearance such that it /might/ work.

It's my suggestion that there is also something "going on" in
intelligence that is difficult to explain on the level of firing
neurons, just as there's something "going on" in computation that's
difficult to explain on the level of gates on a silicon wafer with
particular electromagnetic properties.

I would say that victory in a domain without any analysis of whether
the program can function in other domains with even minimal sharing of
structure is not Artificial Intelligence. In addition I do set the bar
high for programs that I cannot convince myself operate in any way that
directly maps to the primitives of intelligence - some of which include
the ability to interact with an external world that is composed of
objects with persistent identity, the ability to form intuitive
predictions and increase that ability through experience, the ability
to introspect about prior thought and use that introspection to make
decisions, and the ability to translate abstract thoughts into
concrete, controlled motor function. If I do not see a mapping from any
of these constructs to the program, I cannot accept at face value that
such a program is progressing to intelligence, nor that simply
increasing the resources available to such a program will cause it to
hit "critical mass" and suddenly become intelligent. Accepting this at
face value would be the same as accepting that bamboo towers and
runways will bring cargo planes, if only the reproduction is accurate
enough.

I want them to do all of these things at the same time, and improve the
performance (if slightly) of all of them by improving an individual
skill. I want shared structure that enables a computer to quickly adapt
to a new domain by application of past experience in a different
domain.

Effectively, this statement is true, because we don't have AI yet. If
we were producing progressively better general-purpose reasoners, then
I could see the merit of assigning AI-value to them. We aren't. The
last well-known general purpose reasoner I know of is SHRDLU, which
could be taught arithemetic by instructing it to think of numbers as
collections of blocks.

Call me when games allow interaction with the world in some way other
than weapons fire, spell casting, and limited-option decision making.
In reality, all that's happening here is the transformation of gamers
into restricted-domain reasoners. It's also the reason why some
variants of Eliza can pass the turing test, when there's very obviously
nothing which can be called "intelligent" floating around in there.

Infants don't learn languages by reasoning out that every sentence needs
a (possibly implied) noun phrase and a verb phrase. They perform a lot
of experiments with no scientific method. Mimicry and feedback seem to
be enough.

Computer folks know that, because computer languages contain almost no
redundancy (as used to resolve ambiguities), aren't DWIM and have
pedantic compilers with truly awful diagnostics, learning one's first
through trial and error is painful, and so syntax is often taught
rigorously. But that's all hindsight and deep insight. Your students'
strategy seems quite reasonable if their only experience is in
biological languages with good feedback from their "conversation partner."

What, exactly, is the cargo cult's mistake? Seabees came and built
runways and control towers, men put funny headphones on, and the planes
came. Mimicking this looks ridiculous TO US, because we have superior
domain knowledge of aeronautics. Absent that knowledge, we could say
that they err in persisting for five years when no planes have come, but
that suggests that the cultists are to somehow know how long to wait for
results. Given that the original was a one-time event for a culture
which (I'm guessing) had an oral history stretching back many
generations, even a several-generations-long experiment might not be
unreasonable.

[If you'd have asked me yesterday whether I'd defend cargo cultists, I'd
have been insulted at the implication. I never really thought about it
before, just thought what Feynman wanted me to think.]

I meet people all the time who seem to have only the most tenuous grasp
of logic. In fact, I'd hazard that, for the majority of any given
society, Aristotle and Descartes might as well never have existed. It's
not that they are completely illogical, but they certainly don't operate
through rigourous reasoning, and often can't see the flaws in the
systems they believe.

So the interesting question is, when seeking artificially intelligent
behaviour, are we looking for computers to act like the best of us (in
which case, perhaps "Artificial Brilliance"?) or the rest of us?

If the computation was designed by a person, seeking to explain it in
the behaviour of the hardware it's running on is perhaps incorrect. It's
like looking at a chalkboard full of mathematics and saying "the chalk's
really on to something there".

Since we design with logic, we can approach zero redundancy, something
biological systems don't exhibit.

Explaining human behaviour, in isolation, in terms of neurons seems very
difficult. But if we start at the lowly cockroach, we see something that
wouldn't seem to take too many neurons to emulate.

But I agree with you that pursuing a pure neural net approach, merely
because biological systems do it that way, is a cargo cult approach.


My comments on game AI weren't meant to imply that it represents the
future, merely to say that some areas of AI have been advancing, because
there's both quasi-objective metrics and motivations for the people in
that field. AI people seek to get the right fitness criteria for the
training or population culling within their experiments, but I think
that it's equally important to have appropriate fitness criteria for the
researchers themselves, otherwise they end up playing in their own theses.

Military (and eventually civil) logistics is another similar area.
Results were wanted, money was spent, results were gotten. Since funding
domain specific intelligence (or solutions) research has a payoff,
whereas general intelligence is a money pit, domain specific is where
the progress is being made.


Anyway, we may rapidly be approaching (or worse) the limits of my
insights in this area.

From your comments, I'd say you follow the progress, er, machinations,
of the AI community. Do you have any pointers for the uninitiated to
collections of stuff that's more toward the seabees' end of the runway
than the natives'?

I may be misunderstanding you here, but I don't believe this is
correct. Any redundancy in a biological system costs an organism
energy. It seems obvious that evolution will get rid of such
organisms in favor of organisms that don't have redundancy. Did
I misunderstand your point? Did you have a specific example in
mind?

Initially I was thinking specifically of the human brain. Examples exist
of people who've lost quite a lot of brain tissue to trauma and
continued to live quite normal lives. However, given our limited
understanding of the brain, this is not a very solid argument.

Your assertion only holds in an evolutionary environment selecting for
minimum energy use. Why do I have two kidneys, two testes, two lungs?

I'm not happy with my prior response. How does one measure redundancy in
a large neural network? I think the brain has a large number of
redundant neurons, in the sense that a lot of them can die or be removed
without measurable impairment.

However, as you point out, selection has been favouring larger brains
for some time now, so in that sense, the extra brainpower must have some
benefit. I suspect that it is in rapidly coming up with witty things to
say to the opposite sex at parties.

In all cases - brain, kidneys, testes, lungs, etc. we have
"spare" so that we don't die if something goes wrong with the
other one. But then they're not "spare", are they? They're
absolutely necessary for keeping you alive when something goes
wrong. It's only "redundant" if you don't mind catastrophic
failure. Yeah, granted, a human *could* live without them,
but I sure wouldn't want to be that human.

Bringing this back to computers, I think it's good to design
things with "redundancy". Except, again, I don't believe it's
really redundancy. It's only "redundant" if you don't care what
happens when something goes wrong. Usually you do care.

Cheers,
Bill.

Enough... with hardware that supports it. Our brains are simply wired
up to rapidly obtain the necessary information for language learning.
But there is a difference between doing that and understanding the
wiring itself. Our genetics do really provide a bootstrapping procedure
that we've got to understand now.

It's reasonable up until the 52nd time I explain what s-expressions are
and point them at a tutorial explaining the rules. At that point they
really are just coasting instead of thinking.

I don't think Feynman's point was to attack the cargo cult at all. He
was drawing an analogy between why it didn't work and the same type of
pseudoscience that doesn't work in our culture. In our case, we have
many methods which have been developed to enable us to come to an
understanding of something which appears magical. Since we don't yet
(and concievably won't for many many years due to the seeming exclusion
of accurate and large-scale measurement) understand how the embodied
mind actually processes information, that means we need to apply these
processes to the understanding of intelligence itself.

Without following scientific or systematic philosophical inquiry into
the nature of the general concept of intelligence and its
representation as part of the human mind, we cannot convincingly assert
that our experiments will bring in the cargo planes of intelligence.

I don't think Feynman wanted you to think anything about them, but
instead about the advocates of pseudoscience in a scientific society.

The fact that rigorous logic is learned is actually a valid point in
the study of intelligence. It suggests that it might not be the right
level to describe what's going on. I personally focus much more on the
symbolic aspects of intelligence, with a slightly peculiar connotation
of symbol: something which has identity. I try to stake out a middle
ground between the subsymbolicists and the logicians.

But is it useful? My contention is that the human brain is not really a
well-designed device and is more of a kludge of cognitive ability on
top of a neural net than a reflection of some innate cognitive ability
in neurons.

Unfortunately I'm not convinced that those metrics are actually
measuring intelligence. There is a lot of fascinating stuff going on
there, but I really would hesistate to put the label of AI on, say,
genetic programming. It's not a slight to GP, but just a difference in
classification.

I think it's shortsighted investment to only fund practical and not
basic research. For instance, basic physics research gave us the MRI,
and soon sustainable energy-producing fusion.

Not at all; these are good thoughts.

Actually, it's worse than that. I publish in AI. My homepage has links
to my papers, but they aren't necessarily terribly well written,
particularly because of the need to slip past reviewers and masquerade
as useful research.

While I don't claim to be a classicist in any strict regard,
http://plato.stanford.edu/entries/language-thought/ gives a good
history on some of the previous work in the field and the feud with the
connectionists.

I dunno. I've worked a lot in AI (commercial products dealing
with natural language, not academic papers) and I've used several
major approaches, with varying degrees of "neatness" and
"precision."

What I've observed is that the "imprecise" systems, the ones
which do not satisfy the test of "classicality" in terms of
sequential sound operations on a representational state, are
the ones that work better. They are more efficient and less
likely to be killed or led awry by grammar mistakes in the
input. Something that classifies input according to bigrams
or trigrams and then does very shallow pattern-matching is
often superior at extracting meaning from genuine examples
of written english than a formal parsing system that builds
up deep structure.

That said, connectionist tools such as neural networks are
very helpful in efficiently choosing the "most likely" formal
grammar rule to use next when doing formal parsing. Systems
that used connectionist models in rule selection, applying
backpropagation to train them if they didn't lead to the lowest-
cost parse directly, quickly "learned" to outperform other formal
parsing systems by a factor of ten or more. Given that experience
I'd say that the formalist/classicist camp with their exhaustive-
search methodologies ought to be cheering for the new tools from
the connectionists and scruffies. Instead there seems to be
a fight.

But that's primarily domain intelligence again. What
distinguishes natural-language work is the breadth of the
domain; not only do you have to have a working knowledge of
the language, but for worthwhile results, you also have to
have a working knowledge of the particular domain under
discussion. Pretty much all the systems I built were only
looking for information about a very restricted domain.

Now, asking about general intelligence - what the OP called
"Sentience" -- is at this point a lot like asking a car
manufacturer to build something that's as fast, flexible,
quiet, tolerant of rough terrain, and self-maintaining as
a cheetah. It's not going to happen. The cheetah is many
orders of magnitude more complex than the best cars we can
build. Instead we must make do with "domain-specific" but
useful functionality, where we get great speed on paved
roads and have to tinker and maintain once in a while.

But I also want to point out one other thing. Cheetahs are
self-aware. They have "animal intelligence", which means
they use their brains to interact effectively with the world
around them. That's the intelligence that "human intelligence"
started as. And I think "sentience" has to be considered as
an outgrowth of animal intelligence. Animals don't think
in formal symbols. They don't have language. The fundamental
architecture of thought probably isn't "formal" in any
reasonable sense of the word. Our formalisms, our ability
to make sound inference, our ability to use logic, etc -
the things that the classicists so value that they think
intelligence must be defined in terms of them - are all
lately acquired. And that cheetah is self-aware without
them.

If we could produce a computer whose "consciousness" were
as complex as a cat's, I'd consider it self-aware, though
probably not sentient. And I think that "sentience," though
it probably involves _some_ classicist processing, can
probably only be achieved by a system that actually does
at least that much "non-classicist" processing.

It doesn't work.

It is based not in science, but in magic. No attempt is made to
determine a rational cause; instead a `like evokes like' is used.

Okay, so you're saying you don't want AI reasearchers putting parts
together to create programs whose workings they don't understand: i.e.
emergence. And yet

I've read the responses so far. Very interesting work is going on.
However...

I don't think there is any such thing as sentience in the sense of
self-awareness. When Descartes said, "I think, therefore I am," he
was mistaken. He was wrong at the part where he said, "I think."
Everything else that followed was therefore wrong.

Atoms do not think. They are constrained by the laws of physics.
Brains are just collections of atoms arranged in a fancy pattern.
They are subject to the exact same laws.

Generally I try not to think about this illusion we call life. I
think I'm doing pretty well. Life is just a dream.

I don't think he means to suggests that there's anything mystical or
inexplicable about computation. We created it, and not by accident.

It's difficult to explain celestial mechanics on the level of
arithmetic. So we moved up the abstraction curve, invented calculus, and
lived happily ever after.

We haven't yet found the "calculus" that allows us to easily explain
intelligent reasoning. So intelligence is as mystifying to us as the
retrograde motion of the planets was to the ancients.

With the wrong theory it can seems as complex as the geocentric model of
the universe was, with 55 spheres required to allow the possibility of
the motion that was actually observed.

In your post you conflated the complex behaviour sometimes exhibited by
large numbers of simple things (emergence) with the simple behaviour
sometimes exhibited by people who should know better (throwing something
against the wall and seeing if it sticks). If something emerges from
experiment without planning, that's just luck.

Yes, calculus turned out to be a better language for describing
celestial mechanics than arithmetic, but for many phenomena there is
no calculus simpler than the description of it's constituent parts.
Take as a simple example Craig Reynolds' "Boids". The whole point of
that experiment (simulation?) is that the simplest way of describing
the behaviour of the flock is by describing the behaviour of the
individuals. It's not that Reynolds couldn't find an adequate
"calculus" to describe the flock. He found a spectacular one, it just
happened to involve emergent behaviour which is difficult to find by
analysing the equations.

I appreciate that in the post that I quoted Brian Mastenbrook was
talking about students putting together random bits of code. However
he originally attacked the connectionist AI approach as Cargo-Cult
science, and then in the next post started asking for an emergent
description of Intelegence, which is why I felt the need to post.

Only a twisted reading of my statements would take them as a request
for an "emergent description of Intelligence", when in other posts I
have repeatedly talked about approaching intelligence on a level that
corresponds to philosophical primitives in the concept of intelligence.
Because I cannot say that neural nets have any such correspondence, I
cannot accept that they will become intelligent merely because they
happen to resemble the existing hardware of our brain.

Yes, it's wonderful that some systems can demonstrate wildly complex
behavior out of simple parts. However, the problem is that such
behavior is essentially unpredictable, which is not very helpful when
trying to do research. The general notion of science isn't just about
running and experiment and seeing what works - it's about being able to
draw conclusions from the experiment and modify one's thinking. If the
nature of the domain is that of gross unpredictability, this can't
happen.

Well, atoms alone (probably) don't think. However, when you combine
many of them into a special structure, then this structure gets new
properties/abilities which were not there before. For example the
abilitiy to think.

If we find out what pattern/structure is needed we could assemble
atoms in a computer in a similar way and by this giving it also the
ability to think. The hardware is already here.. now placing the
last parts of matter needs to be done by software.
Programming is nothing else than placing matter into a specific
pattern which creates some effect.

Approaching the nitpick level, but isn't this merely our current
theory?

I mean, we can not know for certain that intelligence does not involve
some magical component (such as a divinely given soul) until we have
succesfully built an artificial intelligence.

I know it's true because I wouldn't want to live in a world where I
couldn't make an artificial intelligence. Therefore, I don't even have
to bother thinking about the possibility that I can't.

Even that wouldn't prove anything, unless you are ready to make
some very conservative(!) assumptions about what magic(!) can
and cannot do.

Who's to say that a divinity with a sense of humor wouldn't give
a soul to an AI program? Why, or why not, do you presume you do
or don't know what $DIETY would or wouldn't do?

Who's to say that humans doing hard work on an AI program don't
pass on some of the "magic" with which they are infused? Why or
why not?

Basically, you can't say anything *isn't* magic, until you have
a working theory of magic that is able to rule things out. Since
the defining characteristic of most theories about magic is precisely
the lack of ability to rule things out, there's a problem with that.

Self-awareness is actually easier than sentience. Many computer systems
include a model of their own behavior, that they compare with observations
from the external world. That's sufficient to create a limited kind of
self-awareness.

The laws of physics don't necessarily exclude thinking. But you're right
that atoms don't think.

Your use of the word "just" is highly misleading. All the value is in the
organization.

In any case, look up the "systems reply" to Searle's Chinese Room analogy.
I'm sure you would be a big fan of Searle (who is an AI critic). But the
"systems reply" addresses your confusion head-on. Namely, that the overall
system can have interesting properties which none of the constituent parts
have in isolation.

I belive the tecnical term for self awareness is auto-epistemic logic.
See More, R. C. Autoepistemic logic,
in Non-Standard Logics for Automated Reasoning.

You are assuming that the fact that there is a description of the phenomena
means that there is a deterministic model for it.
In fact Quantum Electrodynamice can give rise highly nonliear behaviour.
You could say that caos is the rule and order the exception that lasts
over time. Roger Penrose postulates, in Shaddows of the Mind, that the
bioelectric field surrounding the brain is in a quantum collaped state.
(Solenoid effect in the micro-tubules)
He goes on to conjecture that quantum effects are neccesary to model the
mind.
Thus he submises a computer does not have the capacity to medol it.
Personally I see no reason why computers can't model nonlinear systems.
(There are some limitations. In the interval delta t being modeled the
function
must be bound polynoninally or no number of digits suffice to express the
number.)
Personally I have been looking for neural "loopback" and adjusting for the
error term.
A method called error biffucation.
(given linear system Ax=b where x is unknown we know x + delta x where
delta x is a
unknown error. but A(x+delta x) = b + delta b
so X delta x = delta b which we can solve. substituting gives
A delta X = A (x + delta x) - b)
It seems to me this can be used to model recognition.
Futher more a new mathematical tool called "Integrate and fire pulse
coupled oscillation"
may be used to modell colation.

I thus summise that the brain is a fractally composed set of non-linear
system solvers using
error biffucation and colating using integrate and fire pulse coupled
oscillation.
The "prime" integrator (factal tree root) is what we call conciousness.
Well, sigh, it needs more work.

A magic component would not change anything, because we would emulate it
too. If magic exists we can look at two aspects of it:
1) algorithmic component
2) randomness

To 1):
If the laws of magic are not 100% random it means they have more than 0%
of "law" inside. When magic follows laws we can exactly tell how magic
would behave under certain circumstances. Therefor we could emulate the
algorithmic component of magic with our computers.

Most of our universe follows this way. Only Heisenbergs uncertainty and
some few physical phenomenons produce something which cannot be computed
by algorithms.

To 2):
If the magic has some random parts (and is not full driven by "laws") we
can emulate these components too. We have sources to create real random
input (for our programs).
The random has to be like real random, if not it would have a pattern
and would automatically become computable. So any source of random will
be enough to emulate the randomness of magic.


This way, even if magic exists (this would be some behaviour of our
universe which we don't know good enough yet) it will not stop us from
creating real intelligence. We could emulate all components of magic
either by software or from some external generator of randomness.
We would have to find out all parts of our brain which follow the
predictable "laws of magic" and programm these rules.
In all other situations we would give random input into our programm.

I don't say that this is the easiest thing to do, which has ever be done
on our planet. Probably it is one of the most complex things which could
be done in our world :)
However, I only want to say that it logically must possible to create
intelligence.

This has a strange, vague similarity to scientific experiment. Because

We can't. I think this term is ill defined.
Sentience is supposed to be what distinguises uf from animals.
I think research, if anything, has made this distinction more fluid.

you're saying "he was" therefore you mean that "what followed" was
true.

and a false premise doesn't make a conclusion ("what followed")
false. e.g.:

descartes thinks implies 2+2=4 ;; questionable
descartes thinks ;; false (you say)
therefore
2+2=4 ;; true

I think that once we get intelligent machines, creating one that acts
plausibly stupid or ignorant (like us humans) will be even more of a
breakthrough. The first AIs are likely to be annoying know-it-alls.

As to the original question, how about "sentient: able to use Google or
a dictionary to discover the meaning of unknown words."

I say any animal that can learn to differentiate between seeing another
animal and seeing itself in a mirror is sentient.

Until Descartes comes along to refute what I say, yes. Of course,
Descartes is dead. So I've got at least one thing going in my favor.

I wasn't aware of that. I'm just using English. Maybe there exists
some language spoken by people which does not have any concept of self
reference.

Anyway, I don't see why we can't come up with some form of synthetic
intelligence. All that is really required (not to imply that this is
easy) is to take a set of defined cognitive functions that we can test
for in humans and figure out a way to emulate those functions by
machine. The emulation does not have to be precise or anything. It
just has to be able to pass the tests.

This is essentially what Turing said, although I think he copped out
on the nature of the testing. People are easy to fool.

So the first challenge is to create a set of defined cognitive
functions along with tests that unambiguously determin the existence
and extent of those functions. Once a set of functions and tests is
agreed upon, it is then just a matter of time before a machine can be
made to pass the tests.

There are of course many specific problems that have already been
identified. Speach recognition is a big one. Lots of progress has
been made there. Visual recognition is somewhat harder, but there are
some results in that area.

Creativity would be harder I think. We don't have a good definition
for that (test) that I know of. Trying to make a machine compose
pleasing music is probably too ill defined a goal to shoot for.

I think the act of creating good tests will prove to be just about as
difficult as creating algorithms that can pass those tests. The
problem lies in defining the tests.

But if intelligence was intimately connected to the presence of a
divine soul, it would not be mathematical. Then all machines that we
would be able to build would lack a component that only the divine
being would be able to control and put into things.

An analogy that might indicate that things aren't as simple as they
seem is the difference between "cookbook" math and true
understanding. We see that there is a difference even though for a
particular problem the result would be the same.

An "algorithmic intelligence" would be analogous to a cookbook
understanding of math.

Another argument, which I feel is devastating to hard AI, is the
"hermeneutical hall of mirrors" argument, wherein the point is made
that even when machines appear to behave intelligently, they only do
so because we project meanings onto their behavior. The intelligence
they appear to manifest is our own reflected back to us.

Early in our marriage, 40-some years ago, Mrs. Williams would return
from shopping complaining about the unreasonable prices. Having aired
her complaints, she'd then ask me to unload her car laden with
purchases. After the unloading, I'd ask her: "I thought you said the
prices were unreasonable. Why did you buy them? Are you
unreasonable? Only an unreasonable person would pay unreasonable
prices." The discussion always headed downhill after such an
observation. -- Walter Williams, economist

The hall of mirrors argument, imo, is irremediably tainted because it
works in the opposite direction as well: once you've decided that some
entity isn't behaving intelligently (in the sense of "human"
intelligence") there is no behavior the entity can exhibit that will
necessarily make you change your mind. A little historical research will
find plenty of essays in which the author argues that some subset of h.
sap. (said subset not including the author) may exhibit a remarkably
cunning simulation of "real" intelligence but is not in fact capable of
reasoning.

Considering the number of computer users who appear to believe that

I only think you think because I project meaning onto your behavior. In
reality, you don't, and I can now proceed to completely ignore you.

I guess this raises the question - if an AI gets offended at you and
the other Searlites' comments, and wipes out all of humanity, who's
left to say it doesn't think? (Or, less violently, if we send an AI on
a robotic spacecraft to explore other solar systems, and Earth is wiped
out by the Rogue Comet of Doom, who's left to play the Searlite
semantic tricks?)

self reference in language merely reflects self awareness of a

i didn't mean it's impossible. i'm not even sure self awareness

self awareness ;-)

I meant a "scientific" definition - one that would serve to guide as

Weak. This could be done with simple pattern recognition. You're way

Concepts are not defined by language. I think what you meant was
a word or phrase that means self awareness.

I thought we already had. It may be low-rent, but we've got something
(the Turing test takers, e.g.).

The point of my query, if it isn't clear, is to motivate thought on
how to make a *truly* intelligent machine - no B.S. - one that in
every sense of the notion "intelligent" passes, and one that truly
*is* intelligent rather that one that merely has the appearance
of intelligence.

But I use the term "intelligent" here in a colloquial sense. To translate
that to a more scientific and precise notion (but probably still way off),
such a machine would need to be both "sentient" and "reasoning."

I think you may be right. Defining "sentient" and "reasoning" is step
one on the road to defining tests.

Hi Christian,

This is a great point. I would say that a "soul" is essentially
a "will." We may eventually be able to make machines that are
both "sentient" and "reasoning" (refer to a parallel post I just
made), but without a "soul" such an entity's will, if existent,
must be synthetic (e.g., "protect all humans from harm"). At least
that's the way it seems to me.

I also should comment that I've wondered if, like our Creator has
done for us, there may be a way for us to infuse into our created
machine a piece of ourselves that would give it this "soul" or will.

So when I see behavior in other people, the intelligence they appear

I see. So you see a reflection of what you believe is your self
awareness reflected in my use of the first person pronoun?

It's time I fessed up. I'm a FORTRAN program written in the late
60's. Does that mean I pass the Turing test? The secret is in the
random number generator used to drive unpredictable behavior. I have
a thermal sensor in a nice hot cup of tea.

I'll admit that my awareness feels convincing at times. But only at
times.

I don't understand what this "soul" would be doing with us.
It is interesting to see, that some people believe that there is
something like a soul.
Even today most brain-scientists are very sure that there is no such
thing like a free will. I would not be overly amazed if they can prove
it in 20 years.
On some beeings you can obviously see their "algorithmic" behaviour,
which has nothing to do with a soul. There is for example some fish
which is doing some "dance" whenever he sees a girl-fish. In an
experiment they showed a male fish a dummy of a female fish and he
started with his exact dance moves, and he did this always when the
dummy was showed to him. For such complex life forms like humans it is
nearly impossible for us to see structures (besides reflexes).

However, only because the human beeing is very complicated it does not
mean that we have some thing like a soul.
See also my other posting that explains why a soul can also not exist,
or, why we will also be able to program one. A soul is also nothing but
a "computer program".

That's a rather big if. I might be able to go along with that if if I
ever saw anything that violated mathematical law or convinced me that
the brain is not just another Turing machine. My own personal
experience just doesn't support any such conclusion.

Of course this is just my opinion and my experience.

As I already intimated, it directs our will. It's the "top-level loop"
of our algorithm.

Had you couched this in more careful terms, I would have thought you

See Mary Shelly's Frankenstein. I believe the idea was that the good
doctor could not create life per se, but he could put a bit of his
soul into it.

I've more or less discounted the existence of a divine creator. But
there is a certain appeal to a sci-fi idea that we are simply a part
of the universe that has broken itself apart into many pieces in an
attempt to understand its self. Not that I actually subscribe to that
idea.

Set aside the philosophy and theology of the issue, I think the
apparent existence of the mind to be the most fascinating thing about
the universe. I don't think The Big Bang holds a candle to it by
comparison.

Unless the laws of mathematics are mutable, it seems that everything
is the way it is without the need for any kind of creation event. If
we solve the problem of creating a machine mind that is as good or
better than the human mind, I expect there will be some controversy.
How long it will take to do that I don't know. It may also be that we
can never fully understand it. I already find it to be quite magical
that the letter 'e' shows up on my display when I, or someone far away,
types an 'e'. Yet all that is has been engineered. Math has not. So
far as we know, it is only discovered.

One of the coolest things I've read was in Carl Sagan's book Contact.
I made sure to read it before the movie came out. In it, there is a
rather interesting discussion about the constant Pi. As far as I
know, Pi can't be anything other than what it is. But in the book,
there is a "message" buried deep down in the number. I won't spoil
it here. Read the book. It is better than the movie.

There is an exit strategy for people who wish to cling to a creator.
In physics, math is really a tool for creating models. The models are
no good until they have been confirmed by experimental observation.
Even then, if you buy into Hume, that empirical evidence is of limited
value. Math may be immutable. But math != physics. Math is just a
tool.

I leave this as a small room for doubt in my own philosophical world
view. That said, I think Roger Penrose is seriously stretching things
in his book, "The Emperor's New Mind." I find his arguments against
the possibility of AI/SI whatever you care to call it (I prefer
synthetic over artificial because the synthetic is indistinguishable
from the natural) to fall strongly into the wishful thinking camp.

Currently the weight of scientific evidence that I am familiar with
leads me to conclude that a human-like synthetic intelligence is quite
possible and perhaps even likely. It just requires deeper
understanding on our part to achieve it. I think once that happens,
the sales of anti-depressants will truly skyrocket.

My only real fear is that people will trust synthetic intelligence
more than the real thing. Just because the machines will be smarter
doesn't mean they will be infallible.

I've sort of got the opinion that there are things which
are holy -- family, love, truth, compassion, joy, life,
etc... This doesn't really require or involve the kind
of God who is a "who", or even a God separate in any way
from the universe itself. It just *is*. Every religion
in the world is just a shadow of what you hold in your
heart when you percieve the world in a state of reverence.

What's holy is that which we hold in reverential regard.
So, each of us chooses what is holy, and for some folks
it's everything, and for some it's nothing.

Not that this has much to do with Lisp, but perhaps on
some level this sort of capacity is part of what we
regard as sentience -- the ability to self-consciously
choose, in some matters, our attitudes and how we allow
things to affect us.

How could you possibly distinguish one from another?

Suppose there's "scientific definition" of "sentinent" and a test
for sentinence based on that definition. Wouldn't it be possible
to create a machine which merely has the appearance of
intelligence which does it best passing this test? we assume other
people are intelligent because they appear intelligent to us,
there's no way we can test if they are sentinent/self aware,
because of the "special access" sentinent being has to its own
mental states and events. you can't prove anything but yourself
has such "special access" like you can't know, how would it feel
to be something else.

sentinent and reasoning intelligent being is antopomophic
intelligent being, and yes human intelligence is the only one we
know. it doesn't mean intelligent being must be sentinent.

the reason we need smarter machines is to help us solve our
problems. i'm not sure sentinence is all that important for
problem solving and trying to create Artificial Sentinence
distracts us from the practical goals.

once we've created artificial sentinent beings they might come up
with their own problems to solve, e.g.: equal rights,
artificial-beings marriage etc.

Just because something isn't infallible doesn't mean it is not more worthy

If concepts are not defined by language, just what is language?

Concepts may or may not be limited by language, but there is strong evidence
that for a given culture and population, those concepts that are not
conveyable in the language are, in fact, not conceived by representative
members. New concepts generates new language to convey the concept, at least
amoung a given (sub-)population.

Here the issue is a bit different.
The scientists started out asuming that we have a free will.
Then they looked more detailed on the brain and came to the conclusion
that there is no place for a free will.

Anyway, free will is not possible as it would break "laws" of nature.
The molecules in your brain are forced to behave in a special way. So
they "force" you to act in a specific pattern (there is no will at all,
no person/intelligence who is deciding the pattern and making descisions
how you should act). If you had a free will you could change the way
how the molecules in your body assemble them self.
Although particle X has to move down because it was pushed into this
direction by another particle (or molecule, whatever) your will forces
it against physical principles to move into a different direction,
enabeling you to say what you "really" want - you would have a free will.

I am not so certain about this. There are some people who have very
good arguments that we were created by an intelligence. If this
intelligence is a living creature, or if it is some strange kind of
"nature laws" is not sure.

But for example take it this way:
if you get some kilos of sand from the beach, climb on a high building
and then let the sand fall down... what do you expect of the sand?
You probably expect that it will fall down somehow, without any
specific pattern. I am sure that you would be highly confused if you
go downstairs and find how the sand has written the faculty function
in Lisp. How often you might throw around sand, it will never fall in a
way that it writes Lisp programs. This is randomness.

Another example:
in a school you give the pupils some dice, and every pupil has to throw
it 100 times and write down the number.
If one kid has 100 times on his paper a "3" you would not believe him
that he did it correctly. Because 100 times a 3 is information, not
randomness. An intelligence is needed to create information.

Last example:
You maybe heared that in the 1925 some people found eggs of dinosaurs
during an expedition in the Gobi desert. Funny was, the eggs were
arranged in a square. The conclusion of the paleontologists was:
these eggs were already discovered by some humans before.


What my examples hopefully illustrate: whenever we find even very simple
structures like squares, letters, etc. we are certain that they were
produced by an intelligence, because information cannot simply appear
out of nothing. But then let us take the by far most complex structure
in the known universe - the human brain.
Here we suddenly say it can develop from alone. There is no intelligence
needed to be involved in creating this structure.
In other words: let some monkeys type, in some time a nice Lisp program
will appear.


Some people want to establish a new field of science, called
Intelligent Design.
If you are interested in mathematical "proofs" that we cannot develop
without a creator google for intelligence design.

Next sentence is _not_ meant offensive:
I think your view of mathematics is too naive.

I don't know your mathematical background... but maybe you want to look
into the issues of the beginning of last century, where math stoped to
work and needed some big changes. And you could look for information
regarding Gödel's incompleteness theorem. Possible starting point:

If you really have some time (2 hours), I _highly_ suggest to read this:
http://www.kurzweilai.net/articles/art0134.html?m=1

This is a text of Ray Kurzweil about his "Law of accelerating Returns".
I am of course critical too, but anyway, I regard it as one of the most
important texts at all.
He explains why in 30-40 years we will have computers, millions of times
more intelligent than humans.

Is this meant to be some sort of argument against evolution?
Because, if so, it's a *very* bad one.

In the absence of a credible definition of "information",
that statement doesn't qualify as either true or false.
It's manifestly not true that intelligence is needed to
make anything analogous to "rolling a 3 100 times".

I'm not sure what significance that's supposed to have, but
it sounds interesting anyway. Can you tell me more? (I asked
Google, but it doesn't seem to have heard the story.)

This is not true. It is very common to find patterns,
some of them very intricate and beautiful, that are well
explained in purely naturalistic terms. For instance,
naturally formed crystals make all sorts of elegant
patterns, which arise simply from the laws of physics.
(Similar patterns would doubtless arise from other
possible laws of physics, so the fact that the laws
of physics give rise to crystal growth doesn't seem
like good evidence that the laws of physics are themselves
the work of an intelligence.)

"Suddenly"? You surely don't think anyone says "All
those other ingenious bits of design in the natural
world, obviously they're the result of an intelligence
at work -- but the human brain isn't"?

> In other words: let some monkeys type, in some time a nice Lisp program

I think you need to learn a lot more about how evolution
is actually thought to work by people who believe in it;
it doesn't at all resemble your "let some monkeys type"
caricature.

> Some people want to establish a new field of science, called
> Intelligent Design.

It is clear that some people want to establish *something*
called "Intelligent Design". I regret that it doesn't look
much like a field of science; more like a strategy for
attacking science. (Google for "intelligent design wedge"
to find out more.)

> If you are interested in mathematical "proofs" that we cannot develop

I am a mathematician, and a Christian (and therefore more
sympathetic to at least some of the aims of these people
than most). Every such "proof" I have seen has been rubbish.
I don't rule out the possibility that there might be some
non-rubbish proof, and if you have one then I would be
very interested to see it.

But that is AI as the term is typically used. Look at an AI textbook,

That's not necessarily so. That brains have gotten larger does not
mean that must have been selected for. For instance, it might be that
something else, that had larger brains as a consequence, was what was
selected for. Larger brains might even be a net cost, so long as some
unavoidably associated benefit is great.

Even Dennett and other Darwinean maximalists admit, albeit
reluctantly, that not every feature was selected for.

That makes sense for something like Eliza, but consider a
chess-playing program, for example. If it plays well, then
it really does play well. It doesn't just seem to because
we're projecting onto its behaviour.

OTOH, is is playing well because of "intelligence" or because
of a good "brute force" (or even "fancy search") algorithm?

Intelligence isn't really about behaviour so much as about
how the behaviour is produced.

That's why people can resist the behavioural evidence:

But they'd need an alternative explanation of the behaviour,
and that can be compared with other candidate explanations.

In some cases, it may actually be that we are projecting
meaning onto the behaviour.

Sure, but presumably we can show that they are wrong.

That doesn't mean that all such claims are always wrong.

Excuse me, but Intelligent Design does not follow the scientific method.
Please don't read what's below as an attack; it's not intended as one.
But I'm going to explain, point by point, what the scientific method *IS*,
and compare it to what the Intelligent Design people are doing. This is
not perjorative in any way; this is strictly a comparison. My intent is
to show that Intelligent Design and the Scientific Method have so little
in common that they cannot, under any circumstances, be considered to be
the same thing.


Scientists form hypotheses - this the Intelligent Design people have done.
Of course, everybody does this. Most of us call our hypotheses
opinions and don't pursue them using the scientific method. I
personally form a lot of hypotheses when I watch seagulls at the beach,
about what they're doing and why. But that doesn't make me a scientist.

Scientists then design experiments by using their hypothesis to try to
predict future events given some set of circumstances. This the ID
people have not done; their sole hypothesis has no predictive power.

Scientists then perform experiments by either bringing about the
circumstances required by their experimental design and studying
the results, or by examining nature to find circumstances matching
their experimental design and studying the results from those.
Lacking any hypothesis with predictive power, the ID people
can design no experiments; therefore they cannot perform them.

If the results of experiments are at variance with the prediction
made on the basis of a hypothesis, scientists then abandon that
hypothesis. Some may kick and moan and argue about it for years,
but eventually, a hypothesis which has less predictive power than
some other hypothesis is abandoned. This the ID people will not
do. In fact those who abandoned the sole hypothesis they've
advanced cease to *BE* the Intelligent Design people.

That which does not follow the scientific method is not science.
Science and the scientific method are not concepts that can be
separated. One who does not use the method is not a scientist.

Nobody can stop them from using the word "science" to describe
what they are doing. But the fact is that what they are doing is
not the scientific method. Therefore the assertion is simply
false.

That is not to state that the hypothesis they advance is false;
in fact it may be true. But it simply isn't a hypothesis about
which science can be done.

That is an interesting topic. I think I agree that people tend to form

they don't HAVE to.

It depends on whether or not one could create a conclusive test for
sentience. As a simple example, let's say I want to test your
knowledge of the capitals of the 50 states. If I ask you to name them,
and you do so correctly, then one may conclude with certainty that you
have knowledge of the capitals of the 50 states.

However, you might have misunderstood me, or rather, I might not
have expressed myself very well. By "appearance of" I mean, essentially,
the non-conclusive and/or subjective tests, like the Turing test.

You keep spelling "sentinent" - the online dictionary has no entry
for this word. It also has no entry for "antopomophic," so I can't
respond intelligently until you define your terms or rephrase.

I never said this was the point of my query, i.e., to make
"smarter machines." Perhaps we do need smarter machines to
solve problems, but my questions are academic.

I tend to agree. I just think the concept of sentience is highly
intriguing, and being able to have a machine do it would prove
we understand what it is all about.

Yes. Now go compute pi to the last digit in base 2. (Use two's
complement.)

Where do the properties of numbers come from? I can get the same
results with (+ 2 3) and (+ 3 2). Where did that law come from? For
that matter, who decided on the decimal representation of Pi and all
those many infinite series that converge on Pi?

Could things have been decided otherwise?

oh, ok. i didn't look at it from this angle. i understand the
motivation, but i still find it impossible task. the only
sentience we're directly aware of is our own. sentience of others
we conclude from their likness to us. other people act like me,
they're built like me, they must feel and think like, just like i
do. well, they also tell me that they feel and think and i don't
have reason to not believe them.

animals act and are built, well, quite like people, they don't
tell us that they can think and feel, but the more they are like
people - more "intelligence" we attribute to them. but we can't
be sure they are sentient in the way we are.

machines may be made to act like people. as they are now they are
built very different from us though. we have one reason less to
think of them as sentient beings. they can be made to tell us
what they think and feel - then we'll have one reason more. but
we won't know for sure they are sentient in a sence humans are
sentient.

Both papers have the same information. One has a much smaller
Kolmogorov complexity.

You do not need intelligence to create information. The laws of
thermodynamics (which is intimately related to information theory)
work just fine in the absence of an intelligent observer.

On the island of Kvadehuksletta one can find piles of rocks arranged
in perfect circles about a meter in radius. However, it appears that
these are natural formations.

Who says that? Most evolutionists believe that the brain evolved from
similar, but slightly less complex brains such as those found in other
primates.

Thank you for your explanations.
I just want to state that I am not a follower of ID but just wanted to
point out to David that there are other possible options available.
Perhaps I spent too much time with talking about ID while for me the
link to Kurzweil was much more important ;)

Yes, agreed. Some people came up with a definition for the word science
which is usually used when talking about it.
Of course this "official definition" is objectively not right, as any
definition by definition isn't, so other people could (if helpfull or
not) give another definition of it.

I am not a follower of Intelligent Design, but they explain with statistical
arguments that it is not possible that a brain can evolve.
If you want to learn more about these arguments please google a bit,
as I cannot defend the position as I am not involved enough into the
thoughts behind it.

Exactly this discussion will become very important as soon science
can prove that there is no thing such free will.
I suppose we will be forced to change the way how laws work.
We probably need to redefine several aspects of it..
As science evolves our understanding of what a crime is does evolve
too. Perhaps in 100 years some computers who are some billion times
more intelligent than we are can come up with a definition of crime
that describes this subject by the movement and patterns of some
molecule structures. Something which is extremly different from our
current understandings of it.

Perhaps they will describe some patterns... and when these patterns
come up some where (something we see as a "crime") other patterns
are started as a result of it: move some molecules (putting the
ciminal into a prison (or whatever might exist in 100 years)).

I understood it this way: it is just a warm up for the average surfer
that one can read on internet sites about Intelligent Design.
I am not very involved into ID, so I don't know their more detailed
explanations. I just wanted to point out some places where these
arguments could be found.

You can visit http://www.intelligentdesigner.de/ and contact the author

Hmm, I supposed there would be more information about this issue, like
the conclusions. The author of the linked site can you probably tell
more about it (and perhaps give some sources).

I think my wording was very bad.
Well, as I understood it, ID says that information cannot appear out of
nothing. You are describing some order/regularity (like structures that
you can find in nature) and not about information. For example it would
be hard to find some trees in nature who grew in a way (when observed
from a helicopter) that they form the letters which itself are the source
code of a scheme compiler.
I mixed some terms, sorry for that.
If you want definitions I have to refer you to the linked site.

Thanks for your comments.

So in other words the weather predictions, based on mathematical models,
is predictable.
You fail to take into account the "butterfly effect". Highly complex
behaviour is
possible even in simple systems. There is certainly room for "free will"
in our
understanding of nature. A model of the human brain would be simular.
You can see general outline of predictable behaviour but would be unable
to estimate
the exact flow of thought over time.

If there's no free will the constructions like "we should" or "we
shouldn't" don't work: we don't decide to punish a criminal, we
simply do it because laws of nature dictate us to.

I am not an intelligent Designer, but I suppose they don't see a problem
that NNs work, cause they were created by an intelligence.
I suppose Intelligent Design sees no problem with intelligence when some
intelligence was involved. What they would find odd if in a storm some
metal parts of a mountain fall down to the ground in a way that a computer
is created which runs a NN. ;-)

And if you google a bit, you should be able to find competent rebuttle of
essentially every claim the ID folk make. The statistical arguments that I
have seen from ID are naive, to be charitable. They certainly haven't
"explained that it is not possible that a brain can evolve".

good day..

I have been lurking here in the shadows for quite some time now, finally
feeling the urge to step into the light (knowing that after posting i am
probably going to regret this).

The difference between "Chaos" and "Information" lies in our
understanding and interpretation. We create information by relating
observations to past experiences and aquired knowledge.

more clearly:

If something is chaotic to us it is only because we are unable to see a
pattern.
If something is information to us it is because we are able to see a
pattern and can connect the observation made with our already aquired
knowledge.

it is not really important that a letter has a sender who crammed a lot
of stuff into it for us to read and understand. it is that we as the
recipients can relate to the letter's content. while knowing that there
was a sender who supposedly HAD to say SOMEthing in that letter makes us
search more keenly for bits of information while reading it.. the
crucial part is not the assembling, but the disassembling. we can
disassemble almost anything the way we see fit.

if you and me were to hop into a helicopter, fly around until we found a
wood, I would show you how out of the many trees you saw there, I could
pick some out, shaping the character #\A.

have fun,
