Aristotles Nicomachean Ethics, based on lectures that he gave in Athens in the fourth century BCE, is one of the most significant works in moral philosophy, and has profoundly influenced the whole course of subsequent philosophical endeavour. It is soundly located within a philosophical tradition, but its argument differs markedly from those of Plato and Socrates in its emphasis on the exercise – as opposed to the mere possession – of virtue as the key to human happiness, offering seminal discussions of ethical issues that are practical in their intent. Topics covered include the role of luck in human wellbeing, moral education, responsibility, courage, justice, moral weakness, friendship and pleasure. This accessible new translation by Roger Crisp follows the Greek text closely and also provides a non-Greek-reader with the flavour of the original. The volume also includes a historical and philosophical introduction and notes on further reading.
