If we imagine anything that we should call a
justification, some private regularity
, it must be
something which, if we saw it, we should call a regularity.
But what would in our case mean seeing his private
regularity? We haven't given it any
sense. That is, we have indeed given the expression to feel
what he feels sense but with
15
particular criteria for the
identity. If we now talk of identity &
don't wish to use
these criteria we are left
without any unless we give fresh ones. And of course I know
perfectly well that we are thinking of criteria similar to the ones of
physical objects only we can't apply any such criteria
in our case &
that's what we mean by
talking of the privacy of the objects. Privacy
here really means the absence of means
of
comparison. Only we mix up the state of
affairs when we are prevented from comparing the objects
with that of not having fixed a method of comparison.
And in the moment we would fix such a way of comparing we would no
longer talk of ‘sensations’.
