Philosophers engaging in moral theory aim to systematise morality. Morality encompasses norms and principles governing human interactions, often considered universal and impartial. Common-sense morality, based on intuitions, guides theory construction. It highlights self/other asymmetries, agent-centred prerogatives, and distinctions like intention vs. foresight. Ethical considerations extend beyond morality, including personal development and projects. Critics find morality too demanding, alienating, and incompatible with special obligations. Some oppose codifiable principles, emphasising agents’ responses to the right reasons. Debates explore morality’s scope and the role of impartiality. Critics like Bernard Williams argue against moral theory’s inescapable obligations and pervasive influence.
