Ideas of geniuses

There are a lot of great ideas of philosophers that say that all ideas of geniuses are born and develop unconsciously. The same is characteristic for people who suffer from mental disorders. There are enough people who accepted this idea that were considered to be geniuses. According to them ideas appear in their heads like the sparks in the flame.
Goethe, for example, said that he made up many of his poems as if he was in the fit of somnambulism.
Mozart accepted that the musical ideas appear unconsciously in his mind as if they were his dreams. And Goffman often said to his friends that he was working with the piano with closed eyes and then he manifested everything that was told to him from somewhere.
According to Voltaire all genius works were created instinctively.
In fact thousand of geniuses claim they were working unconsciously as if they were the negotiators between the perfect and great something that really created the masterpiece and the existing reality.
Moreover many geniuses provoked the hot flashes to the brain artificially as for example Schiller put his feet into the ice. Milton and Dekart were working with head thrown back. Rousseau though over his works under the bright sun.
Probably all these geniuses were using the stimulating ways instinctively. And it is unnecessary to mention that some geniuses drank alcohol to stimulate their creative work. Socrates, Seneca and some others abused alcohol so much that some of them even had alcoholic addiction.
