For the notion of progress in the arts, (either spiritually or artistically) has been discredited by many respectable intellects (Kierkegaard and Baudelaire above all, both of whom encountered the idea when it first reared itself in its present form in Europe).

The Art of painting is itself an intensely personal activity… a picture is a unique and private event in the life of the painter: an object made alone with a man and a blank canvas... A real painting is something which happens to the painter once in a given minute; it is unique in that it will never happen again and in this sense is an impossible object... And it is something which happens in life not in art: a picture which was merely the product of art would not be very interesting and could tell us nothing we were not already aware of. The old saying, “what you don’t know can’t hurt you”, expresses the opposite idea to that which animates the painter before his canvas. It is precisely what he does not know which may destroy him.

I do not know if there are in fact such things as definable social standards of aesthetics that would have any historical or artistic value, but whether there are or not it seems clear to me that for the painter nothing less than complete personal involvement of a moral nature will do.
