Quote by Bentham, Jeremy
"The question is not whether beings of other species are rational, but whether they can suffer."
More from Bentham, Jeremy
"It is the greatest happiness of the greatest number that is the measure of right and wrong."
"Nature has placed mankind under two sovereign masters, pain and pleasure."
"The question is not, Can they reason? nor, Can they talk? but, Can they suffer?"
"All punishment is mischief; all punishment in itself is evil."
