Genius' was a word loosely used by expatriot Americans in Paris and Rome, between the Versailles Peace treaty and the Depression, to cover all varieties of artistic, literary and musical experimentalism. A useful and readable history of the literary Thirties is Geniuses Together by Kay Boyle-Joyce, Hemingway, Scott Fitzgerald, Pound, Eliot and the rest. They all became famous figures but too many of them developed defects of character-ambition, meanness, boastfulness, cowardice or inhumanity-that defrauded their early genius. Experimentalism is a quality alien to genius. It implies doubt, hope, uncertainty, the need for group reassurance; whereas genius works alone, in confidence of a foreknown result. Experiments are useful as a demonstration of how not to write, paint or compose if one's interest lies in durable rather than fashionable results; but since far more self-styled artists are interested in frissons á la mode rather than in truth, it is foolish to protest. Experimentalism means variation on the theme of other people's uncertainties.

which begs a question. What precisely is genius? I believe that genius is not a person but a process, a process in which someone determines to uncover their gift and, for a period, is able to step inside it. The “gift” is a self-explanatory state, and like a prize awarded in a DNA lotto — say, being born into beauty or into wealth — genius is no reason for arrogance.
