Although Aristotle was a friend and student of Plato, he did not agree with Plato’s theories on morality. Like many Greeks, Aristotle did not believe in the existence of inherently bad behaviors. A behavior cannot be either good or evil, but a person can have good or bad character traits. Aristotle said that all people are composed of a combination of vice, which are bad character traits and virtue which are good character traits. He uses this concept to explain his thesis that ultimately Virtue is a disposition of the Golden Mean. This is explained in Aristotle’s Nicomachean Ethics. Aristotle believed that dispositions, feelings and capacities are three of the things that make up the soul. As explained in his book of ethics, a disposition has to be learned in response to a situation. For example we learn to wear certain styles of clothing. In America, it a norm for men to wear pants; skirts and dresses are typically considered women’s clothing. Men could wear dresses if they wanted to, and they are physically able to do so, but most men choose not to. Most American men have a disposition to wear pants.
