"Creativity is something people use in adapting to everyday living," said Dr. Gordon Kirschner, a psychoanalyst who helped organize seminars on the psychology of creativity that brought together psychiatrists and local people in the arts at the Washington School of Psychiatry last spring. The series, open to the public, will continue next fall as the medical men probe the mysteries. Kirschner said the seminars have been "fun" and tend to confirm the following creative stages: "It's necessary to get into a kind of secure state of risk-taking and throwing out ideas in a rather loose, careless fashion as a beginning . . . Some kind of problem is recognized and the person begins to play around with ideas . . . Then there seems to be a stage where the person interacts with what has already been done: the artist begins to react with the colors on the canvas . . . or the writer begins to feel the characters come to life. There is a third stage in which things have to be organized and a great many of the wonderful possibilities have to be put aside because they don't really fit . . . A certain amount of renunciation and reexamination in the cold light of morning has to go on."
