"The thinking man must oppose all cruel..." - Quote by Albert Schweitzer

“We must fight against the spirit of unconscious cruelty with which we treat the animals. Animals suffer as much as we do. True humanity does not allow us to impose such sufferings on them. It is our duty to make the whole world recognize it. Until we extend our circle of compassion to all living things, humanity will not find peace.”

“Reverence for Life affords me my fundamental principle of morality, namely, that good consists in maintaining, assisting, and enhancing life and that to destroy, harm, or to hinder life is evil. Affirmation of the world - that is affirmation of the will to live, which appears in phenomenal forms all around me - is only possible for me in that I give myself out for other life.”

“What 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.”

“While it is true that science, to the extent of its grasp of causative connections, may reach important conclusions as to the compatibility and incompatibility of goals and evaluations, the independent and fundamental definitions regarding goals and values remain beyond science's reach.”

“Pity was meant to be a spur that drives joy to help misery. But it can be used the wrong way round. It can be used for a kind of blackmailing. Those who choose misery can hold joy up to ransom, by pity.”

“I claim to be a conscientiously immoral writer.”

“A person who has a cat by the tail knows a whole lot more about cats than someone who has just read about them.”

“Dogs feel very strongly that they should always go with you in the car, in case the need should arise for them to bark violently at nothing right in your ear.”

“Even snakes are afraid of snakes.”
