45. We got to know the nature of
calculating by learning to calculate.
we learn by doing –
but we don’t get to know the nature of
anything –
if by ‘know’ you mean – know with certainty
yes – we may develop – explanations –
descriptions –
of what it is we do –
but there is no one account-
what we have is possible accounts –
and the value of any account –
is that it is useful to us – at the time –
in the circumstances that we do –what we do
point
being –
another account may be useful to us –
under different circumstances
I find it quite extraordinary –
that Wittgenstein – didn’t see this –
but I guess if he had –
he wouldn’t have written a book –
on certainty
