In light of J. D. Salinger's recent death and the talk of his avoidance of publication over the years ("There is a marvellous peace in not publishing"), the career of Gerard Manley Hopkins offers an interesting comparison. I'm fascinated by the fact that none of Hopkins' works were published until after his death. He kept at it over the years, made sure his friend Bridges gathered them together in an album, and in 1883 wrote a prayer that God would dispense of it all according to his will, "that he would have them as his own and employ or not employ them as he would see fit." Two years prior, he had written in a letter to Bridges about the need to live by faith even in regards to the disposal of his work, "Now if you value what I write, if I do myself, much more does our Lord. And if he chooses to avail himself of what I leave at his disposal he can do so with a felicity and with a success which I could never command. And if he does not, then two things follow; one that the reward I shall nevertheless receive from him will be all the greater; the other that then I shall know how much a thing contrary to his will and even to my own best interests I should have done if I had taken things into my own hands and forced on publication." In a letter to Bridges in 1886, Hopkins seemed more certain that his work should be distributed when he expressed his belief that works of art are meant to be shared in order to do its good, "We must then try be known, aim at it, take means to it." Yet, the only active effort he made toward publication was to send an occasional piece to the Jesuit newsletter.
