I do not photograph nature. I photograph my visions. Quoted in PBS episode of American Masters - Man Ray

The tricks of today are the truths of tomorrow.

Throughout time painting has alternately been put to the service of the Church, the State, arms, individual patronage, scientific phenomena, anecdote and decoration … all the marvelous works that have been painted, whatever the sources of inspiration, still live for us because of absolute qualities they possess in common. The creative force and the expressiveness of painting reside materially in the colour and texture of pigments, in the possibilities of form invention and organisation, and in the flat plane on which these elements are brought into play.

There is no progress in art, any more than there is progress in making love. There are simply different ways of doing it.
