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 don't like to get in front of people.

Why do men fight who were born to be brothers?

But whether it be dream or truth, to do well is what matters. If it be truth, for truth's sake. If not, then to gain friends for the time when we awaken.
