What do you guys think about just swapping in 'chess' in place of
'math' for the purposes of some language game.
You can play chess with physical pieces, but it's also symbolized, has
a notation. You have primitive rules (a grammar) and a sense of
what's illegal. There's also intentionality i.e. there's a goal for
the player, not just aimlessly pushing pieces.
You can play chess in your head, against yourself, or with another
player with whom you're in communication somehow.
Computers play chess.
I'm just saying chess has all the elements, is a good stand in for math.
People don't believe in a Platonic Realm where "perfect chess objects"
play "perfect chess" but they do know the difference between making
logical moves in a generalized notation, versus accidentally knocking
the pieces over and needing to start over or whatever.
If you want to talk about idealized pawns, as distinct from any
physical pawn in a special case chess set, as a "chess object", that's
fine. We could notate that in Python (a logic used by some
philosophers in the FOSS community -- Ian Bicking for example (just
blogged his talk at Djangocon:

Stuart may recall I mentioned Richard Stallman as one of the more
articulate professors of ethics of our time (professor = one who
professes).
