“Behind joy and laughter there may be a temperament, coarse, hard and callous. But behind sorrow there is always sorrow. Pain, unlike pleasure, wears no mask. Truth in art is not any correspondence between the essential idea and the accidental existence; it is not the resemblance of shape to shadow, or of the form mirrored in the crystal to the form itself; it is no echo coming from a hollow hill, any more than it is a silver well of water in the valley that shows the moon to the moon and Narcissus to Narcissus. Truth in art is the unity of a thing with itself: the outward rendered expressive of the inward: the soul made incarnate: the body instinct with spirit. For this reason there is no truth comparable to sorrow.” – Oscar Wilde, “De Profundis”
