This edition of The Nicomachean Ethics features a freshly researched translation by Adam Beresford that presents Aristotle’s foundational ethical lectures in modern, standard English. The work explores the fundamental question of what it means to be a “good person” and how to achieve a flourishing life (eudaimonia). Aristotle argues that happiness is an “activity of the soul in accordance with virtue,” covering moral virtues like courage and justice alongside intellectual virtues like wisdom. Central to the text is the doctrine of the golden mean, which suggests that virtue lies in a middle path between the extremes of excess and deficiency. The book also provides deep insights into the nature of friendship, pleasure, and the relationship between individual character and the state.
