Happiness is nothing more than good health and a bad memory.

The friend of nature is the man who feels himself inwardly united with everything that lives in nature, who shares in the fate of all creatures, helps them when he can in their pain and need, and as far as possible avoids injuring or taking life.

Love . . . includes fellowship in suffering, in joy and in effort.

The true worth of a man is not to be found in man himself, but in the colours and textures that come alive in others.

When man learns to respect even the smallest being of creation...nobody has to teach him to love his fellow man. Compassion for animals is intimately connected with goodness of character, and it may be confidently asserted that he who is cruel to animals cannot be a good man.

Affirmation of the world, which means affirmation of the will-to-live that manifests itself around me, is only possible if I devote myself to other life.

The gratitude that we encounter helps us believe in the goodness of the world, and strengthens us thereby to do what's good.
