- CH It depends on what you know (and believe) about math. foundations. If
- you understand basic ZF set theory, as described, for example, in Fraenkel,
- Bar-Hillel, and Levy, then you start having an inkling about where they're
- coming from. Quine's NF was an attempt to get around the class hierarchy of
- russell. Nowadays, many people think you shopuld start in category theory,
- modeling logics in toposes. But if you don't know math, it's a bit rash to
- dismiss it all as ravings.
-
- In my experience, objectivist writings ignore the entire area because the
- authors were math. incompetent; but tastes differ.

- SG Philosophy is the context of science. Science (inc/math) cannot prove
- nor refute philosophy. Philosophy is the study of the basic facts of existence
- whereas science is the study of non-basic facts. Studying the philosophy of
- math is proper, once a specific philosophy has been proven as the context.
- Randall and Holmes bypassed the need for philosophy by using math in place of
- philosophy. They flirt with metaphysics in a manner suggesting that math
- bases meta instead of the proper hierarchy: meta bases math. And rational
- knowledge is hierarchical (eg, arithmetic prior to alegebra). It may even be
- that Randall and/or Zeleny have parts of an objective philosophy of math (tho
- improbable). That would be irrelevant since it would need some, particular
- philosophy for validation. Even the most abstract science cannot justify
- science. Science has far too much prestige in the modern world. It must be
- subordinate to philosophy, hopefully an objective philosophy, but to SOME
- philosophy. Philosophy must not be made consistent with science. It is science
- which must be made consistent with philosophy. Science always contains an
- implicit philosophy which must be judged without any reference to science.
- I studied phil. of language under a professor who permitted students to
- debate philosophy while demanding blind faith in an unexamined "science" of
- language (There is no science of language). When I inferred the philosophy
- implicit in this "science" of language it was consistent with her philosophy.
- She strongly resisted the implications of this "coincidence." I noted that she
- would have rejected any science of language inconsistent with her philosophy
- but got no reply. Apart from the intellectual fraud, philosophy causes science.
