Let us not violate the RIGHT of the artist to express exclusively his own experiences and introspections, disregarding everything that happens in the world beyond. Let us not DEMAND of the artist, but — reproach, beg, urge and entice him — that we may be allowed to do. After all, only in part does he himself develop his talent; the greater part of it is blown into him at birth as a finished product, and the gift of talent imposes responsibility on his free will. Let us assume that the artist does not OWE anybody anything: nevertheless, it is painful to see how, by retiring into his self-made worlds or the spaces of his subjective whims, he CAN surrender the real world into the hands of men who are mercenary, if not worthless, if not insane.
