Virtue ethics emphasizes the importance of an individual's character and virtues in determining what constitutes a good person, focusing on qualities like temperance, courage, wisdom, and justice. Plato and Aristotle are central figures in this philosophy, stressing that happiness (eudaimonia) stems from virtuous living and the development of both moral and intellectual virtues. While virtue ethics offers a motivational approach to morality and emphasizes education and role models, it also faces challenges, such as the lack of concrete guidance in crisis situations and the difficulty in uniformly defining what makes an action virtuous.
