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

An honest religious thinker is like a tightrope walker. He almost looks as though he were walking on nothing but air. His support is the slenderest imaginable. And yet it really is possible to walk on it.

A philosopher who is not taking part in discussions is like a boxer who never goes into the ring

Not how the world is, but that it is, is the mystery.

I am sitting with a philosopher in the garden; he says again and again 'I know that that’s a tree', pointing to a tree that is near us. Someone else arrives and hears this, and I tell him: 'This fellow isn’t insane. We are only doing philosophy.

The real discovery is the one which enables me to stop doing philosophy when I want to. - The one that gives philosophy peace, so that it is no longer tormented by questions which bring itself into question.
