Echeñique discusses Aristotle's views on moral agency and voluntariness and presents a theory of moral responsibility that is both original and compelling.

This new translation of Aristotle's Eudemian Ethics, noteworthy for its consistency and accuracy, is the latest addition to the New Hackett Aristotle series. Fitting seamlessly with the others in the series, it enables Anglophone readers to read Aristotle’s works in a way previously impossible. Sequentially numbered endnotes provide the information most needed at each juncture, while a detailed Index of Terms guides the reader to places where focused discussion of key notions occurs.
