Aristotle's Ethics by Hope MayHope May offers a new interpretation of Aristotle's account of happiness - one which incorporates Aristotle's views about the biological development of human beings. May argues that the relationship amongst the moral virtues, the intellectual virtues, and happiness, is best understood through the lens of developmentalism. On this view, happiness emerges from the cultivation of a number of virtues that are developmentally related. May goes on to show how contemporary scholarship in psychology, ethical theory and legal philosophy signals a return to Aristotelian ethics. Specifically, May shows how a theory of motivation known as Self-Determination Theory and recent research on goal attainment have deep affinities to Aristotle's ethical theory.
