Until he extends the circle of his compassion to all living things, man will not himself find peace.

Think occasionally of the suffering of which you spare yourself the sight.

The human spirit is not dead. It lives on in secret... It has come to believed that compassion, in which all ethics must take root, can only attain its full breadth and depth if it embraces all living creatures and does not limit itself to mankind.-

Until he extends the circle of his compassion to all living things, man will not himself find peace. - The Philosophy of Civilization.

A man is ethical only when life, as such, is sacred to him, that of plants and animals as that of his fellow men, and when he devotes himself helpfully to all life that is in need of help. -Albert Schweitzer.

It is our duty to share and maintain life. Reverence concerning all life is the greatest commandment in its most elementary form. Or expressed in negative terms: “Though shalt not kill.” We take this prohibition so lightly, thoughtlessly plucking a flower, thoughtlessly stepping on a poor insect... Reverence for life comprises the whole ethic of love in its deepest and highest sense. It is the source of constant renewal for the individual and for mankind.
