A quote
“What else do you want of me, then?” you ask; “the will is still mine.” Well, the will in this case is almost everything, and not merely the half, as in the proverb “A task once begun is half done.” It is more than half, for the matter of which we speak is determined by the soul. Hence it is that the larger part of goodness is the will to become good. You know what I mean by a good man? One who is complete, finished,—whom no constraint or need can render bad.
