Quote from : Dedalus Book of Surrealism 2: The Myth of the World Book

The real importance of automatism lay in the fact that it led to a different relation between the artist and the creative act. Where the artist had traditionally been seen as someone who invents a personal world, bringing into being something unique to his own 'genius', the surrealists conceived themselves as explorers and researchers rather than 'artist' in the traditional sense and it was discovery rather than invention that became crucial for them.
