Utilitarianism is a classic work of ethical theory, arguably the most persuasive and comprehensible presentation of this widely infl uential position. Mill argues that it is pleasure and pain that ought to guide our decision-making-and not the pleasure and pain of any one person or group, but the summative experience of all who are affected by our actions. While he didn't invent utilitarianism, Mill offered its clearest expression and strongest defense, and expanded the theory to account for the variety in quality that we find among specifi c pleasures and pains. Today, Mill's version of the "Greatest Happiness Principle" is a standard premise in many moral arguments within the academy and in practical ethical and political deliberation.
