The philosopher is not a citizen of any community of ideas, that is what makes him a philosopher.

The world is made up of facts, not things.

The child learns to believe a host of things. I.e. it learns to act according to these beliefs. Bit by bit there forms a system of what is believed, and in that system some things stand unshakeably fast and some are more or less liable to shift. What stands fast does so, not because it is intrinsically obvious or convincing; it is rather held fast by what lies around it.

He who lives in the present lives in eternity.

Philosophy hasn't made any progress? - If somebody scratches the spot where he has an itch, do we have to see some progress? Isn't genuine scratching otherwise, or genuine itching itching? And can't this reaction to an irritation continue in the same way for a long time before a cure for the itching is discovered?

A tautology's truth is certain, a proposition's possible, a contradiction's impossible.

No one can think a thought for me in the way that no one can don my hat for me.
