 A person is constituted by his body and his mind. They are parts or aspects of him. For that very reason, it is fitting that he have primary say over what may be done to them—not because such an arrangement best promotes overall human welfare, but because any arrangement that denied him that say would be a grave indignity. In giving him this authority, morality recognizes his existence as an individual with ends of his own—an independent being. Since that is what he is, he deserves this recognition.
