Art is made to trouble but science reassures.
A painting without something disturbing in it – what's that?.

In art there is only one thing that counts: the bit that cannot be explained.
Emotion should not be rendered by an excited trembling; it can neither be added on nor be imitated. It is the seed, the work is the flower.
