The role of Logic
From: Tractatus Logico-Philosophicus by Ludwig Wittgenstein
6.52 We feel that even if all possible scientific questions be answered,
the problems of life have still not been touched at all. Of course
there is then no question left, and just this is the answer.
6.521 The solution of the problem of life is seen in the vanishing of
this problem.
(Is not this the reason why men to whom after long doubting
the sense of life became clear, could not then say wherein this
sense consisted?)
6.522 There is indeed the inexpressible. This shows itself; it is the
mystical.
6.53 The right method of philosophy would be this. To say nothing
except what can be said, i.e. the propositions of natural science,
i.e. something that has nothing to do with philosophy: and then
always, when someone else wished to say something metaphysical,
to demonstrate to him that he had given no meaning to
certain signs in his propositions. This method would be unsatisfying to the other
—he would not have the feeling that we were teaching him philosophy—
but it would be the only strictly correct method.
6.54 My propositions are elucidatory in this way: he who understands
me finally recognizes them as senseless, when he has climbed out
through them, on them, over them. (He must so to speak throw
away the ladder, after he has climbed up on it.)
He must surmount these propositions; then he sees the world rightly.
7 Whereof one cannot speak, thereof one must be silent.
