People are rational because of their natural physiology or their acquired rationality

Acquired people originally have a perceptual understanding to govern the action, as the age increases, the experience increases, it becomes rational, rationality can be said to be the way to do things, when they can't do it by their own sensibility, or when they are hurt, people have to choose rationality, rationality can also be said to be a kind of helplessness.

A human being is like a tabula rasa, and a baby is mentally no different from an animal. Whether it is nature or reason, it is acquired.

The "homo economicus" hypothesis in classical Western economics holds that human beings are completely rational and can make choices that maximize their own interests. Simon, winner of the 1978 Nobel Prize in Economics, revised this assumption and proposed the concept of "bounded rationality", arguing that human beings are in a state of "bounded rationality" between perfectly rational and irrational. Homo economicus (Greek:

homo oeconomicus), also known as the "homo economicus hypothesis", that is, it is assumed that human beings think and act rationally, and that the only economic benefit they try to obtain is the maximization of material compensation. This is often used as a basic assumption in economics and certain psychological analysis. The establishment of microeconomic theory is premised on certain assumptions.

In microeconomic analysis, there are differences in the assumptions according to the different needs of the problem being studied and the theory to be established. However, among the different assumptions of many different economic theories, there is one basic assumption that all economic theories have, that is, the assumption of the "rational man".

In economics, the assumption of a "rational person" is often referred to simply as the assumption of a "rational person" or "broker". Western economists point out that the assumption of the so-called "rational man" is a general abstraction of the basic characteristics of all people engaged in economic activities in the economic society. This abstracted basic feature is:

Everyone who is economically active is self-interested. It can also be said that the economic behavior adopted by every person engaged in economic activities is to try to obtain his maximum economic benefits at his own minimum economic cost.

Human reason is sincerity. Sincerity is also known as truth, self-nature, nature, true self, Buddha nature, truthfulness, dharmakaya, enlightenment, ......It is the root (origin) of all things in the universe, that is, the ontology of the universe in philosophy. Truth transcends all time and space without change, the past has no beginning, and the future has no end.

Eternity. "Sincerity" cannot be discovered by ordinary people, but can only be discovered after reaching a certain level of kung fu through correct cultivation methods. Buddhists believe that one can only discover one's true heart when one reaches the state of a bodhisattva.

Our present mind is often referred to as "knowing mind." The process of transformation from knowing the mind to the true heart is the process of seeking the truth, and it is also the core of Confucianism, Taoism and Buddhism, the excellent traditional Chinese culture.
