The utilitarian "standard of conduct is not the agent's own greatest happiness, but the greatest amount of happiness altogether ..." (P 431a)

Happiness, "being, according to the utilitarian opinion, the end of human action, is necessarily also the standard of morality; which may accordingly be defined, the rules and precepts for human conduct, by the observance of which [a happy] existence ... might be, to the greatest extent possible, secured to all mankind, and not to them only, but, so far as the nature of things admits, to the whole sentient creation." (P 431ab)
