Nature has placed mankind under the government of two sovereign masters, pain and pleasure... they govern us in all we do, in all we say, in all we think: every effort we can make to throw off our subjection, will serve but to demonstrate and confirm it.
Jeremy BenthamWhat 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 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? Why should the law refuse its protection to any sensitive being? The time will come when humanity will extend its mantle over everything which breathes.
Jeremy BenthamIn the mind of all, fiction, in the logical sense, has been the coin of necessity;โin that of poets of amusementโin that of the priest and the lawyer of mischievous immorality in the shape of mischievous ambition,โand too often both priest and lawyer have framed or made in part this instrument.
Jeremy BenthamO Logic: born gatekeeper to the Temple of Science, victim of capricious destiny: doomed hitherto to be the drudge of pedants: come to the aid of thy master, Legislation
