Just out of curiosity, if anyone knows about this and perhaps can correct or
confirm my understanding :

doesn't Godel's proof, insofar as it demonstrates (among other things) that
the number system cannot be reduced to logic (at least the Russell/Whitehead
attempt), lead necessarily to a recognition of numbers as existent (not as
abstract sets or classes), and hence lend support to an affirmation of the
existence of ideal objects outside the human head? This would seem to be a
good field in which to explore Ilyenkov's notion of the ideal as well.

btw, is the reading Vygotsky's "crisis" or Laszlo's?
