Dear Stephen,

Given that, were it not for Plato the question you ask me would
not make sense and could not probably be formulated, I should
not have to answer it.

If that is what you driving at: Mathematical Realism or Platonism is
not a religion, but a conviction which most working mathematician
have been reasonably led to in their practice. As for physicists it is
a prejudice that most share but few find a need to confess.  My only
distinction is that I am quite shameless about it...
