6.52 We feel that even when all possible scientific questions have been answered, the problems of life remain completely untouched. Of course there are then no questions left, and this itself is the answer.
6.521 The solution of the problem of life is seen in the vanishing of the problem. (Is not this the reason why those who have found after a long period of doubt that the sense of life became clear to them have then been unable to say what constituted that sense?)
6.522 There are, indeed, things that cannot be put into words. They make themselves manifest. They are what is mystical.
6.53 The correct method in philosophy would really be the following: to say nothing except what can be said, i.e. propositions of natural science — i.e. something that has nothing to do with philosophy — and then, whenever someone else wanted to say something metaphysical, to demonstrate to him that he had failed to give a meaning to certain signs in his propositions. Although it would not be satisfying to the other person — he would not have the feeling that we were teaching him philosophy — this method would be the only strictly correct one.
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.)
7 What we cannot speak about we must pass over in silence.
You have no need to go out of the house. Stay at your table and listen. Don’t even listen, just wait. Don’t even wait, just be completely still and alone. The world will offer to unmask itself for you, it cannot do otherwise, it will disport itself before you ecstatically.
