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.
The artist must see the war with a unique vision. If he doesn't, then he hasn't added anything to our lives. We can pick up Time magazine and get that account of what happened, but what truly happened we must get from the artist. To me that war was a nightmare and it is best expressed in a surreal way. And that is why it is written in that style and in that attitude. War is a form of madness.
