Keith Johnstone from his book Impro. I highly recommend it.
Once we believe that art is self-expression, then the individual can be criticized not only for his skill or lack of skill, but simply for being what he is.
Schiller wrote of a ‘watcher at the gates of the mind’, who examines ideas too closely. He said that in the case of the creative mind ‘the intellect has withdrawn its watcher from the gates, and the ideas rush in pell-mell, and only then does it review and inspect the multitude.’ He said that uncreative people ‘are ashamed of the momentary passing madness which is found in all real creators… regarded in isolation, an idea may be quite insignificant, and venturesome in the extreme, but it may acquire importance from an idea that follows it; perhaps in collation with other ideas which seem equally absurd, it may be capable of furnishing a very serviceable link.’
My teachers had the opposite theory. They wanted me to reject and discriminate, believing that the best artist was the one who made the most elegant choices. They analyzed poems to show how difficult ‘real’ writing was, and they taught that I should always know where the writing was taking me, and that I should search for better and better ideas. They spoke as if an image like ‘the multitudinous seas incarnadine’ could have been worked out like the clue to a crossword puzzle. Their idea of the ‘correct’ choice was the one anyone would have made if he had thought about it long enough.
I now feel that imagining should be as effortless as perceiving.
