What, then, is truth? Truths are illusions about which one has forgotten that this is what they are.

There is no regular path which leads from these intuitions into the land of ghostly schemata, the land of abstractions. There exists no word for these intuitions; when man sees them he grows dumb, or else he speaks only in forbidden metaphors and in unheard - of combinations of concepts.

They [humans] are deeply immersed in illusions and in dream images; their eyes merely glide over the surface of things and see "forms."

There are no eternal facts, as there are no absolute truths.

The errors of great men are venerable because they are more fruitful than the truths of little men.

Belief in the truth commences with the doubting of all those truths we once believed.
