亚里士多德认为，在人的灵魂中可以看到三类东西，即情感、本能、习惯或品性

Aristotle believes that three types of things can be seen in the human soul, namely emotion, instinct, habit or character. Then he analyzed all three, and believed that virtue is neither emotion nor nature, because emotion and nature itself have no morality, and for themselves, they will neither be praised nor condemned. Therefore, virtue can only be habit or character. Since virtue is a character, what kind of character is it? Aristotle believes that every virtue can not only make a thing itself better, but also make it complete its function. In this case, the human virtue must be the kind of character that can not only make a good person, but also make people fulfill their functions satisfactorily. This character, in Aristotle's view, is "the golden mean".

Aristotle believed that there were three kinds of things that could be seen in the human soul, namely emotion, instinct, habit, or character. He then analyzed all three, arguing that virtue was neither emotional nor inherent, because emotion and nature were not moral in themselves and that they were neither praised nor condemned. Therefore, virtue can only be customary or character. Since virtue is a kind of character, then, what kind of character is it? Aristotle believed that every virtue could make a thing better in itself and complete its function. In this case, then human virtue must be the kind of character that can make people become good people, but also make people complete their functions satisfactorily. This character, in Aristotle's view, is the "middle way".
