Ludwig Wittgenstein

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

When one is frightened of the truth then it is never the whole truth that one has an inkling of.

Never stay up on the barren heights of cleverness, but come down into the green valleys of silliness.

I've been bitten by a python. Not a very big one. I was being silly, saying: 'Oh, it's not poisonous...' Then, wallop! But you have fear around animals.

We define ourselves as intelligent. That's odd, because we're doing the definition - We're creating our own definition and saying, 'We are intelligent!'

I don't like to get in front of people.
