Utilitarianism

Utilitarianism is the moral doctrine which holds that, "actions are right in proportion as they tend to promote happiness; wrong as they tend to produce the reverse of happiness." In Utilitarianism, John Stuart Mill defends the principle that, "pleasure and freedom from pain are the only thing desirable as ends," because they make up the happy life.

"'The Utilitarian doctrine is that happiness is desirable, and the only thing desirable, as an end; all other things being desirable as a means to that end.' - John Stuart Mill"
