From William H. Gass, Finding a Form (Ithaca NY: Cornell University Press, 1996), p. 35—
I believe that the artist’s fundamental loyalty must be to form, and his energy employed in the activity of making. Every other diddly desire can find expression; every crackpot idea or local obsession, every bias and graciousness and mark of malice, may have an hour; but it must never be allowed to carry the day. If, of course, one wants to be a publicist for something; if you believe you are a philosopher first and Nietzsche second; if you think the gift of prophecy has been given you; then, by all means, write your bad poems, your insufferable fictions, enjoy the fame that easy ideas often offer, ride the flatulent winds of change, fly like the latest fad to the nearest dead tree, but do not count the seasons of your oblivion.
