Nicomachean Ethics is considered one of Aristotle's most mature and significant works and is one of the most fundamental works of Western philosophy. For Aristotle, all human actions are done for a purpose, which is happiness – the highest good. According to the philosopher, the attainment of happiness can only exist when a person is virtuous.

Nicomachean Ethics is one of the three treatises that deal with the analysis of the forms and conditions of moral and intellectual virtue according to Aristotle. It examines and analyzes in detail the issues and key concepts posed by the philosopher, such as happiness, responsibility, moral education, moral virtues, practical wisdom, and friendship.
