Ethics has not only to do with mankind but with the animal creation as well. This is witnessed in the purpose of St. Francis of Assisi. Thus we shall arrive that ethics is reverence for all life. This is the ethic of love widened universally. It is the ethic of Jesus now recognized as a necessity of thought...Only a universal ethic which embraces every living creature can put us in touch with the universe and the will which is there manifest.
Albert SchweitzerYou must not expect anything from others. It's you, of yourself, of whom you must ask a lot. Only from oneself has one the right to ask everything and anything. This way it's up to you - your own choices - what you get from others remains a present, a gift.
Albert SchweitzerWhat does Reverence for Life say abut the relations between [humanity] and the animal world? Whenever I injury any kind of life I must be quite certain that it is necessary. I must never go beyond the unavoidable, not even in apparently insignificant things. The farmer who has mowed down a thousand flowers in his meadow in order to feed his cows must be careful on his way home not to strike the head off a single flower by the side of the road in idle amusement, for he thereby infringes on the law of life without being under the pressure of necessity.
