The aesthetics of failure is not total destruction; it is the enjoyment of failure. The degradation of an image is a metaphor for aging and decay – for something to be perfect requires a belief in romanticism. To expect perfection is to turn your back on realism.
To produce a image that is better than the image of the mind is to give rise to a product of catastrophe. (To achieve exactness by design and skill is to reach a point of exhaustion and famine.) It is therefore acceptable to assume that an artist that is categorized as a genius has failed more successfully than one who is mediocre.
