• To affirm life is to deepen, to make more inward, and to exalt the will-to-life. At the same time the man who has become a thinking being feels a compulsion to give every will-to-live the same reverence for life that he gives to his own. He experiences that other life as his own. He accepts as being good: to preserve life, to raise to its highest value life which is capable of development; and as being evil: to destroy life, to injure life, to repress life which is capable of development. This is the absolute, fundamental principle of the moral, and it is a necessity of thought.
