"According to Graham Wallas, a sort of re-ordering process takes place in the brain during creativity, which he calls incubation, A creative person develops interest in a particular subject, gathers supporting material, and studies everything possibly related to it. He calls this first stage preparation. After some time, the accumulated material reaches a boiling point and something incomprehensible goes on during the period of incubation that forms a prelude to the next stage, illumination. In three stages - preparation, incubation, and illumination =- the creative person receives a new insight and finds a solution to the problem, or can rearrange the accumulated material to put it under an all embracing principle."
