No-one who has a real understanding of the art of painting attaches any importance to what we call the subject of a picture - what is represented. To one who feels the language of pictorial form, all depends on how it is presented, nothing on what.

The painting is always conceived as the linear record of a rhythmic gesture: it is a graph of a dance executed by the hand. Not only the artist's eye and hand perform this dance, so does the eye of the beholder.

None the less, perhaps, the highest pleasure in art is identical with the highest pleasure inscientific theory. The emotion which accompanies the clear recognition of unity in a complex seems to be so similar in art and in science that it is difficult not to suppose that they are psychologically the same. It is, as it were, the final stage of both processes.
Roger Fry
