"Critics are like horse-flies which hinder the horses in their plowing of the soil. The horse works, all its muscles drawn tight like the strings on a double-bass, and a fly settles on his flanks and tickles and buzzes. And what does the fly buzz about? It scarcely knows itself; simply because it is restless and wants to proclaim: 'Look, I too am living on the earth. See, I can buzz, too, buzz about anything.'"
