Because I have confidence in the power of truth and in the spirit, I believe in the future of mankind. Affirmation of the world and of life contains within itself an optimistic willing and hoping which can never be lost. It is, therefore, never afraid to face the dismal reality and to see it as it really is.
Albert SchweitzerTo 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.
Albert Schweitzer
