are. What belongs to its application, logic cannot anticipate. It is clear
that logic must not clash with its application. But logic has to be in
contact with its application. Therefore logic and its application must not
overlap.


5.5571 If I cannot say a priori what elementary propositions there are,
then the attempt to do so must lead to obvious nonsense. 5.6 The limits of
my language mean the limits of my world.


5.61 Logic pervades the world: the limits of the world are also its limits.
So we cannot say in logic, 'The world has this in it, and this, but not
that.' For that would appear to presuppose that we were excluding certain
possibilities, and this cannot be the case, since it would require that
logic should go beyond the limits of the world; for only in that way could
it view those limits from the other side as well. We cannot think what we
cannot think; so what we cannot think we cannot say either.


5.62 This remark provides the key to the problem, how much truth there is
in solipsism. For what the solipsist means is quite correct; only it cannot
be said , but makes itself manifest. The world is my world: this is
manifest in the fact that the limits of language (of that language which
alone I understand) mean the limits of my world.


5.621 The world and life are one.
