Never did tell you my theory of writing. If it isn’t spontaneous, right unto the very sound of the mind, it can only be crafty and revised, by which the paradox arises, we get what a man has hidden, i.e., his craft, instead of what we need, what a man has shown, i.e. blown (like jazz musician or rose)-

The requirements for prose & verse are the same, i.e. blow-What a man most wishes to hide, revise, and un-say, is precisely what Literature is waiting and bleeding for-Every doctor knows, every Prophet knows the convulsion of truth.-Let the writer open his mouth & yap it like Shakespeare and get said what is only irrecoverably said once in time the way it comes, for time is of the essence-

JACK KEROUAC, in a letter to Malcolm Cowley (1955)
