Happy Virtue, Painful Surrender

"We therefore agree with Aristotle that what is intrinsically right may well be agreeable, and that the better a man is the more he will like it; but we agree with Kant so far as to say that there is one right act - that of self-surrender - which cannot be willed to the height by fallen creatures unless it is unpleasant."

C.S. Lewis, The Problem of Pain p. 90
