A Good IdeaNo satisfactory way exists to explain how to form a good idea. You think about a problem until you're tired,forget it,maybe sleep on it,and then flash!When you aren't thinking about it,suddenly the answer arrives as a gift from the gods.Of course,all ideas don't occur like that but so many do,particularly the most important ones. They burst into the mind,glowing with the heat of creation.How they do it is a mystery,but they must come from somewhere.Let's assume they come from the"unconscious".This is reasonable,for psychologists use this term to describe mental processes,which are unknown to the individual.Creative thought depends on what was unknown becoming known.All of us have experienced this sudden arrival of a new idea,but it is easiest to examine it in the great creative personalities,many of whom experienced it in an intensified form and have written it down in their life stories and letters.One can draw examples from genius in any field,from religion,philosophy,and literature to art and music,even in mathematics,science,and technical invention,although these are often thought to depend only on logic and experiment.All truly creative activities depend in some degree on these signals from the unconscious,and the more highly insightful the person,the sharper and more dramatic the signals become.Only great writers often write down their great ideas in their life stories and letters.A:Right B:Wrong C:Not mentioned
