Amazon.com description: Product Description: It is improbable that more nonsense has been written about aesthetics than about anything else: the literature of the subject is not large enough for that. It is certain, however, that about no subject with which I am acquainted has so little been said that is at all to the purpose. The explanation is discoverable. He who would elaborate a plausible theory of aesthetics must possess two qualities—artistic sensibility and a turn for clear thinking. Without sensibility a man can have no aesthetic experience, and, obviously, theories not based on broad and deep aesthetic experience are worthless. Only those for whom art is a constant source of passionate emotion can possess the data from which profitable theories may be deduced; but to deduce profitable theories even from accurate data involves a certain amount of brain-work, and, unfortunately, robust intellects and delicate sensibilities are not inseparable.
