A drawing is essentially a private work, related only to the artist's own needs; a 'finished' statue or canvas is essentially a public, presented work - related far more directly to the demands of communication.

The strange power of art is sometimes it can show that what people have in common is more urgent than what differentiates them. It seems to me it's something that theatre can do, but it's rare; it's very rare.

Traditional Chinese art looked at the Earth from a Confucian mountain top; Japanese art looked closely around screens; Italian Renaissance art surveyed conquered nature through the window or door-frame of a palace. For the Cro-Magnons, space is a metaphysical arena of continually intermittent appearances and disappearances.

One of the fundamental reasons why so many doctors become cynical and disillusioned is precisely because, when the abstract idealism has worn thin, they are uncertain about the value of the actual lives of the patients they are treating. This is not because they are callous or personally inhuman: it is because they live in and accept a society which is incapable of knowing what a human life is worth.

In the average European oil painting of the nude the principal protagonist is never painted. He is the spectator in front of the picture and he is presumed to be a man.

Directors like Satyajit Ray, Rossellini, Bresson, Buñuel, Forman, Scorsese, and Spike Lee have used non-professional actors precisely in order that the people we see on the screen may be scarcely more explained than reality itself. Professionals, except fo the greatest, usually play not just the necessary role, but an explanation of the role.
