The human body is the best picture of the human soul.

There can never be surprises in logic.

Where does our investigation get its importance from, since it seems only to destroy everything interesting, that is, all that is great and important? (As it were all the buildings, leaving behind only bits of stone and rubble.) What we are destroying is nothing but houses of cards and we are clearing up the ground of language on which they stand.

Don't think, but look! (PI 66)

My propositions serve as elucidations in the following way: anyone who understands me eventually recognizes them as nonsensical, when he has used them--as steps--to climb up beyond them. (He must, so to speak, throw away the ladder after he has climbed up it.) He must transcend these propositions, and then he will see the whole world aright.

Like everything metaphysical the harmony between thought and reality is to be found in the grammar of the language.

You get tragedy where the tree, instead of bending, breaks.
