-
- ``Formalism'' is a loaded term. People called Ramanujan a ``formalist''
- when he blindly manipulated the zeta function without realizing that it
- had complex zeros. The ``formalism'' of a century ago was ushered out by
- rigor.
-
- In any case, the purely syntactic viewpoint which I advocate doesn't
- have any difficulties. You may refuse for years to give in and admit
- that you're a symbol-pusher too, but I'll be able to take any paper you
- publish and keep the entire mathematical content while removing every
- appeal to semantics. I win. [chuckle]
-
- "Formalism" has been the standard term for a certain philosophy of
- mathematics since Hilbert, at least.
-
- I won't get drawn into an argument about whether formalism is "correct"
- (whatever that means). Why don't we just conclusively solve the easy
- problems in philosophy first, like the meaning of quantum mechanics, the
- mind-body problem, and the nature of good and evil?
-
- Dan appears to believe that he "wins" because Timothy can't prove that
- formalism is wrong. Philosophical arguments being what they are, such
- victories come cheap.
-
- Anyone who is seriously interested in such issues should do some background
- reading. I recommend "The Philosophy of Mathematics", a collection edited
- by Benacerraf and Putnam. This dates from c. 1970; most of the essays are
- post-Goedel's theorem (the Great Divide for this subject, as Benacerraf and
- Putnam point out in their introduction).
