It is easy to conceive how the aesthetic product is to be distinguished from the common artifact, since all aesthetic creation is absolutely free in regard to its principle, in that the artist can be driven to create by a contradiction, indeed, but only by one which lies in the highest regions of his own nature; whereas every other sort of creation is occasioned by a contradiction which lies outside the actual producer, and thus has in every case a goal outside itself. F.W.J. Schelling
