I'm going to 'deal' to them quite soon. Before I was operating on pure
intuition to try to crack the general principles behind general
intelligence. Now that I've got the general principles I'm quickly trying to
put them on a firmer foundation via a proper careful study of the facts. I
should be able to put the hapless SL4 crowd out of their misery quite soon

This is not gibberish, as anyone with a rudimentary knowledge of
Einstein's General Theory Of Relativity and philosophy could tell you:
Google on the 'Relationalism' versus 'Substantivalism' debate for instance.
Relationalists (like Leibniz for instance) thought that the notion of a
'space-time manifold' was simply a convienienent device (an abstraction or
fiction) being used to describe the relational properties of matter.
Substantivalists (like Newton for instance) thought space-time had an
existence over and above the relational properties of matter.
The debate seems to have gone in favor of Substantivalism. In General
Relativity, there are properties of the space-time manifold as a whole which
cannot be completely reduced to the local relational properties between the
matter within it.

Simple mathematical platonism. I think you'll find that a sizable portion
of modern scientists believe that mathematical entities are actually *out
there* in reality, not just astract fictions. The alephs (transfinites)
*are* actual numbers - entities with their own rules of arithmetic. Read
Rudy Rucker's 'Inifinity and The Mind' for very strong arguments that there
are actual infinite entities being referred to.
I further assume that you're talking about Abraham Robinson's

It's a common misconception that 'infinitesimals are just analytic tools'.
On the contrary, they too are actually well defined entities with their own
rules of arithmetic. You obviously haven't read Rudy Rucker's 'Infinity And
The Mind' - probably you should ;) Conway's 'Surreal Numbers' were another
kind of non-standard analysis involving infinitesimals. The point is that
there *are* actual infinitesimal entities there - well-defined numbers with
their own rules of arithemetic - not just 'categories'.

Um... ever heard of David Lewis and modal realism? The Many-Worlds
interpretation of qauntum mechanics? Tegmark's Multiverse theory?
I think many mathematical platonists would insist that if there are
well-defined entities that are proven to be completely logically coherent,
these entities do exist out there something.
Vague notions like 'God' are not well defined and so cannot be compared to
transfinites and infinitesimals, which ARE completely well-defined and

Well of courese if everything physical is computable (as I agree) infinite
entities cannot directly physically affect what we do, but indirectly they
might be needed for a full explanation of reality.
Remember math *is* the manipulation of symbols. We don't need to

Hmm. Most mathematical platonists simply would not agree with you when you
say that: 'math is the manipulation of symbols'! Mathematical platonists
would say that there are mathematical entities out there in objective
reality, which the symbols are referencing.
