Natural law theory states that humans can only live well if they recognise the goods that are natural for them and understand how those goods generate the system of practical guidance that we call morality. Natural law is a long-established and flourishing ethical tradition, with roots in Aristotle and Aquinas, that is increasingly recognised as a worthy competitor to Kantianism, utilitarianism and virtue ethics. The new essays in this collection represent the latest thinking - both constructive and critical - of some of the most important thinkers in the field. They also reflect the growing influence, sophistication and importance of natural law theory within contemporary ethical debate
