Nature attains perfection, but man never does. There is a perfect ant, a perfect bee, but man is perpetually unfinished. He is both an unfinished animal and an unfinished man. It is this incurable unfinishedness which sets man apart from other living things. For, in the attempt to finish himself, man becomes a creator. Moreover, the incurable unfinishedness keeps man perpetually immature, perpetually capable of learning and growing.

There is a powerful craving in most of us to see ourselves as instruments in the hands of others and thus free ourselves from the responsibility for acts which are prompted by our own questionable inclinations and impulses. Both the strong and the weak grasp at this alibi. The latter hide their malevolence under the virtue of obedience: they acted dishonorably because they had to obey orders. The strong, too, claim absolution by proclaiming themselves the chosen instrument of a higher power--God, history, fate, nation or humanity.
