"Animals... are there merely as a means..." - Quote by Immanuel Kant

“We assume a common sense as the necessary condition of the universal communicability of our knowledge, which is presupposed in every logic and every principle of knowledge that is not one of skepticism.”

“Two things awe me most, the starry sky above me and the moral law within me.”

“He who is cruel to animals becomes hard also in his dealings with men. We can judge the heart of a man by his treatment of animals.”

“Killing animals for sport, for pleasure, for adventure, and for hides and furs is a phenomena which is at once disgusting and distressing. There is no justification in indulging is such acts of brutality.”

“There are barbarians who seize this dog, who so prodigiously surpasses man in friendship, and nail him down to a table, and dissect him alive to show you the mezaraic veins... Answer me, Machinist, has Nature really arranged all the springs of feeling in this animal to the end that he might not feel? Has he nerves that he may be incapable of suffering?”

“We cut the throat of a calf and hang it up by the heels to bleed to death so that our veal cutlet may be white; we nail geese to a board and cram them with food because we like the taste of liver disease; we tear birds to pieces to decorate our women's hats; we mutilate domestic animals for no reason at all except to follow an instinctively cruel fashion; and we connive at the most abominable tortures in the hope of discovering some magical cure for our own diseases by them.”

“Nonviolence, applied to very large masses of mankind, is a new experiment in the history of the world.”

“Man becomes not the lord and master of all creation but he is its servant.”

“How can any man be weak who dares to be at all?”
