From an interview with William Faulkner by Jean Stein for the Paris Review
New York, 1956
No one is without Christianity, if we agree on what we mean by the word. It is every individual’s individual code of behavior, by means of which he makes himself a better human being than his nature wants to be, if he followed his nature only. Whatever its symbol —cross or crescent or whatever— that symbol is man’s reminder of his duty inside the human race. Its various allegories are the charts against which he measures himself and learns to know what he is. It cannot teach man to be good as the textbook teaches him mathematics. It shows him how to discover himself, evolve for himself a moral code and standard within his capacities and aspirations, by giving him a matchless example of suffering and sacrifice and the promise of hope.
Writers have always drawn, and always will draw, upon the allegories of moral consciousness, for the reason that the allegories are matchless—the three men in Moby Dick, who represent the trinity of conscience: knowing nothing, knowing but not caring, knowing and caring. The same trinity is represented in A Fable by the young Jewish pilot officer, who said, “This is terrible. I refuse to accept it, even if I must refuse life to do so”; the old French Quartermaster General, who said, “This is terrible, but we can weep and bear it”; and the English battalion runner, who said, “This is terrible, I’m going to do something about it.”
