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 SchweitzerAs we acquire knowledge, things do not become more comprehensible, but more mysterious.
Albert SchweitzerThe deeper we look into nature, the more we recognize that it is full of life, and the more profoundly we know that all life is a secret and that we are united with all life that is in nature.
Albert SchweitzerThe interior joy we feel when we have done a good deed is the nourishment the soul requires.
