392. What I need to shew is that doubt is
not necessary even when it is possible. That the possibility of the
language-game doesn’t depend on everything being doubted. (This is connected
with role of contradiction in mathematics.)
whether doubt is exercised or not–
will depend on circumstances
the ground of any language use –
is uncertainty
if you try to avoid uncertainty –
to deny it –
you will not function effectively
in mathematics –
contradiction renders a proposition –
non-functional
