The "mean" in Aristotle's virtue ethics refers to finding the middle ground between two extremes of behavior, known as vices. This middle ground represents the virtue or moral excellence that a person should strive for in their actions and character. The mean is not a fixed point or exact measurement, but rather a balanced and harmonious way of behaving that promotes overall well-being and flourishing. Aristotle believed that finding the mean requires practical wisdom and the ability to make moral judgments based on the specific circumstances of a situation.
