It seems as though, however the outward
circumstances change, once the
word is fastened to a particular
personal experience, it
now retains its meaning; and that therefore I can now use it with
sense whatever may happen.
To say that I can't doubt whether
I see red is
in a sense absurd as the game I play with the expression “I see
red” doesn't contain a doubt of this form.
It seems, – whatever the circumstances I always know now whether to
apply the word or not.
It seems, at first it was a move in a special game, but then it becomes
independent of this game.
(This reminds one of the way the idea of length seems to become
emancipated from any particular method of measuring it.)
