The principle of utility judges any action to be right by the tendency it appears to have to augment or diminish the happiness of the party whose int… - Jeremy Bentham

Want keeps pace with dignity. Destitute of the lawful means of supporting his rank, his dignity presents a motive for malversation, and his power furnishes the means.

In looking over the catalogue of human actions (says a partizan of this principle) in order to determine which of them are to be marked with the seal of disapprobation, you need but to take counsel of your own feelings: whatever you find in yourself a propensity to condemn, is wrong for that very reason. For the same reason it is also meet for punishment: in what proportion it is adverse to utility, or whether it be adverse to utility at all, is a matter that makes no difference. In that same proportion also is it meet for punishment: if you hate much, punish much: if you hate little, punish little: punish as you hate. If you hate not at all, punish not at all: the fine feelings of the soul are not to be overborne and tyrannized by the harsh and rugged dictates of political utility.

The day has been, I grieve to say in many places it is not yet past, in which the greater part of the species, under the denomination of slaves, have been treated by the law exactly upon the same footing as, in England for example, the inferior races of animals are still. The day may come when the rest of the animal creation may acquire those rights which never could have been withholden from them but by the hand of tyranny. The French have already discovered that the blackness of the skin is no reason why a human being should be abandoned without redress to the caprice of a tormentor. It may one day come to be recognized that the number of legs, the villosity of the skin, or the termination of the os sacrum are reasons equally insufficient for abandoning a sensitive being to the same fate. What else is it that should trace the insuperable line? Is it the faculty of reason, or perhaps the faculty of discourse? But a full-grown horse or dog is beyond comparison a more rational, as well as a more conversable animal, than an infant of a day or a week or even a month, old. But suppose they were otherwise, what would it avail? The question is not Can they reason?, nor Can they talk?, but Can they suffer?
