In Art we know nothing for certain. - Roger Fry

A work of art is a work of art, and nothing else, personal considerations count for nothing.

I fancy all distinctively poetical language ought to be banned and the poetry come out of the quality of the idea and the intensity or passion with which it is expressed.

There is no difference between landscapes and other subjects: in general in painting I try to express the emotions that the contemplation of the form produces in me.
