Hi Roger Clough,
Hi Bruno Marchal
Yes, by new I mean contingent. But Kant, although his examples
are debatable, at least sought a synthetic a priori,
which of course would be a gold mine, or perhaps a stairway
to the divine.
Pragmatism rejects the idea of there being any
such universals, but I think by abduction strives
to obtain completly new results (if actually new I can't say).
I think that's why Peirce came up with the concept of abduction.
The concept is very seductive to me for its possible
power of discovery of something unknown or new.
If comp could do this, I'd not spend a moment more on
simulating the brain. Such a program might be worth a lot of
money in venues such as AI, the defense industry, medicine
and criminal investigation a la Sherlocki Holmes.
Abduction is just one technic among many to do inductive inference
(predicting theories from fact, synthesizing programs from input-
output sequences, finding explanations from data, etc.).
The mathematical theory of inductive inference is a very large
subfield of theoretical computer science and theoretical artificial
Intelligence, or Learning theory. AI is the practice and/or
experimental part of it.
Behavioral Comp is the idea that machines can emulate all 3p aspect of
experience and consciousness.
STRONG AI is the thesis that machine can have 1p experience.
COMP is the thesis that *you* are emulable by a computer.
Famous theorem in theoretical learning theory:
Roughly speaking we measure the "intelligence" (really competence) by
the largeness of the class of computable processes recognized
(explained, inferred) by a machine, or by the number of such classes
(or comobinations).
What is *much* more clever than a machine? Answer: two machines. It is
the non union theorem of Blum and Blum. Actually, and in general, the
gap of intelligence is incomputably big.
A machine which can change its mind n times is also incomputably more
"clever" than a machine which changes its mind m times, if m < n.
(Case and Smith)
A surprising result: a machine which is able to change its mind,
despite he got a correct theory, is again *much more* clever than a
machine which sticks on the correct theory! (Case and Smith).
Case & Al. refuted also a form of strict Popperianism. Machines able
to infer irrefutable theories can learn larger classes, and more
classes, of computable process.
Most result are, as we could expect, non constructive. No machine can
really construct a machine and prove that such machine is more clever
than herself. But of course machine can do that serendipitously, and
machine can build other hierarchies, close to form of biological self-
extension.

Theoretical computer science is a *very* large part of mathematical
logic. With both a deductive and an inference inductive part.
Computer are very peculiar objects. They seem close to what you say
about the supreme monads, but the supreme monads are not Gods, they
are only God reflector, or God mirror. God is more like the whole
truth, I mean the whole arithmetical truth, which contains the many
truth concerning many universal numbers and universal relation between
numbers. The monads are windows through which God can take a look at
itself, but the supreme-monads the universal numbers, are window
enough large so that God can begin to "recognize" itself, so to speak.

http://en.wikipedia.org/wiki/Abductive_reasoning
"Abduction[1] is a form of logical inference that goes from data
description of something to a
hypothesis that accounts for the reliable data and seeks to explain
relevant evidence.
The term was first introduced by the American philosopher Charles
Sanders Peirce (1839?1914) as
"guessing".[2] Peirce said that to abduce a hypothetical explanation
from an observed surprising circumstance
is to surmise that may be true because then would be a matter of
course.[3] Thus, to abduce
from involves determining that is sufficient (or nearly sufficient),
but not necessary, for [b, unclear symbol].
For example, the lawn is wet. But if it rained last night, then it
would be
unsurprising that the lawn is wet. Therefore, by abductive
reasoning, the
possibility that it rained last night is reasonable. (But note that
Peirce did
not remain convinced that a single logical form covers all
abduction.)[4]
Peirce argues that good abductive reasoning from P to Q involves not
simply
a determination that, e.g., Q is sufficient for P, but also that Q
is among the
most economical explanations for P. Simplification and economy are
what call
for the 'leap' of abduction.[5] In abductive reasoning, unlike in
deductive
reasoning, the premises do not guarantee the conclusion. Abductive
reasoning
can be understood as "inference to the best explanation".[6]
There has been renewed interest in the subject of abduction in the
fields of law,[7] computer science, and artificial intelligence
research.[8] "

Yes indeed. Almost the opposite of the comp indeterminacy. With comp

Yes. But nor can a God, or a universe. I am not sure what you mean by
"new".

OK, but this happens in arithmetic too, even without comp. And more
easily shown with comp.

So by new, you mean contingent. But arithmetic is full of many
contingencies. Even many type of very different sort of contingencies.

Tell me what you mean by nominalism, as this term is often used
differently by different people.
