Why is it not the mind that controls a person, but his character?

No matter how much we talk about human rationality, we often do things that are far from it. Think about how often you thought about one thing and did something completely different. This is precisely what describes the saying that a person is governed by his character, not his mind. We will always act on the basis of our temperament and our character, which has developed in the process of education and self-education.
