 The mainstream views in all three of the major approaches to ethical theory—consequentialism, deontology, and virtue ethics—agree on some form of the priority of virtue. Where these views chiefly differ is not on the importance of being good, but on whether being good necessarily benefits us. Virtue ethicists tend to answer in the affirmative, the other two schools in the negative. Building virtue into well-being, as Aristotelians do, may seem to yield a more demanding ethics, and in some ways it does. Yet many deontologists and consequentialists—notably Kant—advocate sterner, more starkly moralistic visions of the good life than Aristotle would ever have dreamt of (e.g., Singer 1972).
