I wouldn't call myself a platonist, but I think others might.
However, I have no problem with "Bishop-style" mathematics.
I believe that the semantics of mathematical languages can
be made sufficiently clear that most of the statements of mathematics
have an objective truth value.
More generally, I believe that the notion of logical truth
can be made precise and objective, and encompasses mathematical
However, though I regard mathematical truth as (very close to) absolute,
I do not imagine that the truth of any sentence is independent of
the language in which it is expressed.
Different kinds of analysis are easily accomodated within
the one mathematics, provided only that one recognises
that mathematics can deal with any domain of discourse.
(or, as in Bishop loosely about multiple domains)
I'm curious to know whether there really are platonists out there
who have a problem with this.
