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.

It should not for a moment be supposed that cultivation of the intellect leads a man to shrink from inflicting pain. Many educated men are no more humane, are in fact far less so, than many comparatively uneducated people.

There are those whose purpose in writing is, by means of the noble qualities of heart which their imagination invents or which they themselves may have, to seek the plaudits of other human beings. For my part, I use my genius to depict the delights of cruelty: delights which are not transitory or artificial; but which began with man and will end with him. Cannot genius be allied with cruelty in the secret resolutions of Providence? Or can one, being cruel, not have genius?

One may say that there is cruelty and even ferocity in some of the pastimes of the people. Occasionally dogs are made to fight, and sometimes men belabour each other with wicker staves, or kill cocks with blows from a club.

My own belief is that in most ages and in most places obscure psychological forces led men to adopt systems involving quite unnecessary cruelty, and that this is still the case among the most civilized races at the present day.

Humans were capable of incredible cruelty, our father wanted me, my sister, and my brothers to understand. And just as dangerous, he made us see, human beings were also capable of looking the other way and remaining silent when awful things were happening all around them.

There is only one thing that arouses animals more than pleasure, and that is pain. Under torture you are as if under the dominion of those grasses that produce visions. Everything you have heard told, everything you have read returns to your mind, as if you were being transported, not toward heaven, but towards hell. Under torture you say not only what the inquisitor wants, but also what you imagine might please him, because a bond (this, truly, diabolical) is established between you and him.

Men are not zoophilists (being-lovers). Not many of them are philanthropists (man-lovers). They are barbarians. And the wrongs inflicted by them on non-human beings are for the most part inflicted simply because they feel like it. Human nature is so constructed that men get pleasure out of doing the most monstrous deeds. It is worse than this. Human nature is so constructed that it contains elements which demand exercise, demand motor expression, and in whose expression the most lamentable and appalling effects are produced.

For it must be noted, that men must either be caressed or else annihilated; they will revenge themselves for small injuries, but cannot do so for great ones; the injury therefore that we do to a man must be such that we need not fear his vengeance.

The only mode which is employed to repress this violence, and to maintain the order and peace of society, is punishment. Whips, axes and gibbets, dungeons, chains and racks are the most approved and established methods of persuading men to obedience, and impressing upon their minds the lessons of reason. There are few subjects upon which human ingenuity has been more fully displayed than in inventing instruments of torture. The lash of the whip a thousand times repeated and flagrant on the back of the defenceless victim, the bastinado on the soles of the feet, the dislocation of limbs, the fracture of bones, the faggot and the stake, the cross, impaling, and the mode of drifting pirates on the Volga, make but a small part of the catalogue. When Damiens, the maniac, was arraigned for his abortive attempt on the life of Louis XV of France, a council of anatomists was summoned to deliberate how a human being might be destroyed with the longest protracted and most diversified agony. Hundreds of victims are annually sacrificed at the shrine of positive law and political institution.

nothing cruel is in fact beneficial; for cruelty is extremely hostile to the nature of man, which we ought to follow.

Cruelty would be delicious if one could only find some sort of cruelty that didn’t really hurt.

Every form of cruelty—whether it be trapping, hunting, the working of ponies in mines, or the practice of vivisection—casts a slur on humanity. These actions demand our attention if we are to make progress as a truly humane society.

Have you a right to torture animals for your pleasure? Have you a right to make their lives amid terror and misery in order to derive some measure of gratification from what are called the pleasures of the chase?
