The artist simply reveals, he doesn't explain. Freud tried to figure this out because he felt it very important to understand what makes a creative person tick. And he said that he had failed. In other words, I don't think that the artist is a scientist; he's almost the antithesis of the scientist. He cannot explain, he can only state. He makes a poetic statement, and the psychiatrist figures out why that is a universal truth. The psychiatrist tells people why they behave the way they do; the artist tells how they behave.
