Quote by Jeremy Bentham
"Nature has made pleasure and pain the lords of mankind."
More from Jeremy Bentham
"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, pleasure and pain."
"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."
