Then it seems to me that at that end, we are in a situation when I say
that I like this and you say that you like that. This is quite a common
situation and provided we both tolerate the differences in opinion, I
have nothing against.

I would not say that I demand. I just express my concern of "good vs.
bad" in Beginning of Infinity. I personally do not say that my
explanation is good, I just express what I feel. Others can agree or
disagree. In the latter case, I do not state that their explanation is bad.
I believe that good and bad is important in moral. When we discuss a
scientific explanation, "good vs. bad" disturbs me.
If to speak about the book Beginning of Infinity in general, it disturbs
me a lot for example that the statement "Problem is soluble" is so often
repeated. It reminds me a marketing campaign. By the way, ANSYS has
adopted recently a nice slogan that a product is a promise
"Every product is a promise: to be functional and reliable; to perform
better than other designs on the market. ANSYS can help you meet the
promises you make."
Probably they have read Beginning of Infinity. To speak seriously, I
would prefer that scientific authors describe their findings in a
neutral way.
Now, to answer your question directly. If Beginning of Infinity cannot
answer questions unambiguously, then I do not understand why it was
necessary to employ so much pathos in the book.

I do not have criticism as such as I have listened to the chapter just once.
I am aware of emergence (or supervenience as philosophers like it) but
frankly speaking I do not understand how it is working. On emergence I
have worked out A Different Universe by R. B. Laughlin but I still far
from understanding.

Let us consider DNA. When we say that they contain information, then
their must be some formal way to evaluate how much information is there.
In this respect, it would be good to take all organic molecules and then
apply this method. Then, if I understand your point correctly, this
method should produce zero for all organic molecules but DNA.
I am personally not aware of such a method. Recently I have discussion
with biologist on nature of information in biology. Let me quote Prof
Neumann in this respect that disagree with the role of DNA as written in
your statement.
http://groups.google.com/group/embryophysics/msg/8df88c387dd48c27
"I understand that you can write a program that generates tree
morphologies. But you designed the program. An organism's DNA does not
contain such a program. The program, if you want to call it that,
resides in the entire material composition of the organism's zygote, and
only part of that is inscribed in DNA sequence.
The forms that we see unfolding in a present-day organism are not the
execution of information in the DNA, but outcomes of a complex set of
physical processes, only some of which are predictable based on the
physics acting on the contemporary materials (including the DNA). Some
of the forms arose much earlier in evolutionary history based on the
cellular materials present at that time and the physical effects
relevant to those materials.
Those original forms (if they were consistent with survival) acted as
structural templates for subsequent canalizing evolution, so that the
present-day unfolding process can neither be attributed to present-day
DNA, or present-day DNA plus present-day physics. The explanation of the
forms and the means of their generation must also take the historical
dimension into account. The DNA sequence reflect this history, but only
partially, and not in the form of a program."
Currently I follow biosemiotics. You may want to look at
Barbieri, M. (2007). Is the cell a semiotic system? In: Introduction to
Biosemiotics: The New Biological Synthesis. Eds.: M. Barbieri, Springer:
179-208.
It is quite a different explanation there. Where it is bad or good, it
is up to you.
As for books, I can offer you a quote from Max Velmans, Understanding
Consciousness
p. 215. "As Popper (1972) notes, knowledge that is codified into books
and other artefacts has an existence that is, in one sense,
observer-free. That is, the books exist in our libraries after their
writers are long dead and their readers absent, and they form a
repository of knowledge that can influence future social and
technological development in ways which extend well beyond that
envisaged by their original authors. However, the knowledge itself is
not observer-free. Rather, it is valuable precisely because it encodes
individual or collective experience. Nor, strictly speaking, is the
print in books 'knowledge'. As Searle (1997) points out, words and other
symbolic forms are intrinsically just ink marks on a page (see Chapter
5). They only become symbols, let alone convey meaning, to creatures
that know how to interpret and understand them. But autonomous existence
of books (and other media) provides no basis for 'objective knowledge'
of the kind that Popper describes, that is, knowledge 'that is totally
independent of anybody's claim to know', 'knowledge without a knower',
and 'knowledge without a knowing subject (see quote above). On the
contrary, without knowing subjects, there is no knowledge of any kind
(whether objective or not)."
Again, it is up to you to decide which explanation is good and bad.

Well, when I occasionally think that I have found a good solution for a
problem with a long history, I ask myself such a question. For me it helps.
As for your proof, you start with an assumption that universals cannot
be dependent on mind. Then you prove that they cannot be dependent on
mind. Or if you prefer a term explanation, you start with a good
explanation that universals cannot be dependent on mind and then claim
the opposite as a bad explanation. You can always do it this way.
However, the modern science is based on nominalism and it has been
pretty successful. Actually I guess all technological advances that has
been mentioned in Beginning of Infinity has been achieved by science
based on nominalism.
This is another logic in Beginning of Infinity that I find strange. In
Dark Ages there was a bad philosophy. Then came a philosophy that helped
to develop a modern science but this philosophy in some respect is even
worse. In my view, something here is wrong.

I have not read Farewell to Reason. There is a small paper by Feyerabend
in Internet and I believe that it is a good summary of his views
