His [ Van Gogh's] pathos is alien to me, especially in my current phase, but he is certainly a genius. Pathetic to the point of being pathological, this endangered man can endanger one who does not see through him. Here a brain is consumed by the fire of a star. It frees itself in its work just before the catastrophe. Deepest tragedy takes place here, real tragedy, natural tragedy, exemplary tragedy. Permit me to be terrified.
