Aristotle writes on virtue and moral character…

Aristotle writes on virtue and moral character in a 325 BCE work, Nicomachean Ethics (sometimes spelled 'Nichomachean'), or Ta Ethika, which is to play a prominent role in defining Aristotelian ethics.

The ten books which comprise it are based on notes from his lectures at the Lyceum and were either edited by or dedicated to Aristotle's son, Nicomachus.

Nicomachean Ethics focuses on the importance of habitually behaving virtuously and developing a virtuous character.

Aristotle emphasizes the importance of context to ethical behavior, and the ability of the virtuous person to recognize the best course of action.

Aristotle argues that eudaimonia is the goal of life, and that a person's pursuit of eudaimonia, rightly conceived, will result in virtuous conduct.
