Thought cannot avoid the ethical or reverence and love for all life. It will abandon the old confined systems of ethics and be forced to recognize the ethics that knows no bounds. But on the other hand, those who believe in love for all creation must realize clearly the difficulties involved in the problem of a boundless ethic and must be resolved not to veil from humankind the conflicts which this ethic will involve us, but allow us really to experience them. To think out in every implication the ethic of love for all creation this is the difficult task which confronts our age.
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.
Albert SchweitzerThe thinking man must oppose all cruel customs no matter how deeply rooted in tradition or surrounded by a halo. We need a boundless ethics which will include the animals also. My life is full of meaning to me. The life around me must be full of significance to it. If I want others to respect my life, then I must respect the other life I see however strange it may be to mine. Ethics in our western world has hitherto been largely limited to the relation of man to man... but that is a limited ethics.
Albert SchweitzerVery little of the great cruelty shown by men can really be attributed to cruel instinct. Most of it comes from thoughtlessness or inherited habit. Extract from 'Memories of childhood and youth.'
