" Art is neither good nor bad, but a clairvoyant vision of the nature of both, and any attempt to align it with morality, otherwise known as bowdlerizing,is intolerably vulgar...Unimaginative realism evokes only the smug pleasure of recognition.the painter becomes popular because he assures everyone else that he sees no more than they see...Art is suggestive rather than explicit: it makes no attempt to persuade into general agreement or provide mediocre levels of explanation...the bold imagination produces great art; the timid one small art. But the healthy eye does not see more broadly and vaguely than the weak eye; it sees more clearly...a real miracle is an imaginative effort which meets with an imaginative response. "
