The ancient Greek philosopher Aristotle profoundly influenced the field of ethics with his concept of virtue ethics. According to Aristotle, virtues are desirable character traits that lie between two extremes, which he referred to as vices. For instance, courage is a virtue that lies between recklessness (excess) and cowardice (deficiency). Aristotle emphasized that the cultivation of virtues leads to a fulfilling life, achieved through practical wisdom, which he called 'phronesis.' Moreover, he believed that virtues are developed through habit and experience, rather than simply by instruction. This idea challenges the notion that ethical behavior can be taught in a didactic manner.
In contemporary discussions, Aristotle’s virtue ethics offers a framework for assessing moral character and behavior. Critics of virtue ethics, however, argue that relying on virtues can lead to subjective interpretations of what constitutes a good life.
