Nichomacheïsche

The Nichomacheïsche Ethik, often rendered as the Nicomachean Ethics in English, is a major philosophical work by the ancient Greek thinker Aristotle. Traditionally dated to the 4th century BCE, it consists of ten books and is named after Nicomachus, Aristotle’s son, with whom the text was likely edited or associated.

The central aim is to identify the highest good for human beings and explain how virtue enables a life of flourishing. Aristotle argues that every activity aims at some good, and the human good is eudaimonia—often translated as flourishing or happiness—achieved through rational activity in accordance with virtue. The work develops the function argument: the good for humans is the activity of the soul in accordance with reason.

Moral virtue is understood as a stable trait developed by habit, lying at a mean between excess and deficiency relative to us, determined by rational principle. Examples include courage, temperance, and justice; the mean varies with context and character. Intellectual virtues arise through teaching, with practical wisdom (phronesis) guiding moral choice. The text also discusses pleasures, the role of external goods, and the significance of friendship in a flourishing life.

Influence and legacy: The Nichomacheïsche Ethik has profoundly shaped Western ethical thought, influencing medieval scholasticism and modern virtue ethics. It remains a foundational reference for discussions of virtue, character, happiness, and the rational organization of ethical life.
