Very little of the great cruelty shown by men can really be attributed to cruel instinct. Most of it comes from thoughtlessness or inherited habit. The roots of cruelty, therefore, are not so much strong as widespread. But the time must come when inhumanity protected by custom and thoughtlessness will succumb before humanity championed by thought. Let us work that this time may come.
Albert SchweitzerOne truth stands firm. All that happens in world history rests on something spiritual. If the spiritual is strong, it creates world history. If it is weak, it suffers world history.
Albert SchweitzerWe must never allow the voice of humanity within us to be silenced. It is humanity's sympathy with all creatures that first makes us truly human.
Albert SchweitzerEthics are complete, profound and alive only when addressed to all living beings. Only then are we in spiritual connection with the world. Any philosophy not representing this, not based on the indefinite totality of life, is bound to disappear.
