Dogmatists of all kinds — scientific, economic, moral, as well as political — are threatened by the creative freedom of the artist. This is necessarily and inevitably so. We cannot escape our anxiety over the fact that the artists together with creative persons of all sorts, are the possible destroyers of our nicely ordered systems. For the creative impulse is the speaking of the voice and the expressing of the forms of the preconscious and unconscious; and this is, by its very nature, a threat to rationality and external control.
