"The so-called rationality also refers to the psychological process in which psychological individuals control and dominate life impulses through perceptual manipulation of reality and reference to reality, and seek interaction with the environment under the guidance of the value system, so as to achieve an intermediary, that is, a balanced state with the environment, thus reducing the tension caused by the existence of life impulses to a minimum. In the rational composition, there is also feeling, which includes the part of human cognition. Without emotion, reason cannot exist independently. Emotion evokes rationality, becomes the source of rationality, and develops rationality; The power of reason comes from emotion. Reason is to help emotions, not hinder them, and always try to satisfy them. However, reason is different from emotion. Rationality serves the individual's own image mode. The most basic core of rationality is "going too far". Therefore, the meaning of reason is always quite subtle and full of sense of crisis. In other words, reason is governed by the principle of reality. Rationality should not only consider whether a certain impulse of life can be realized in the realistic external environment, but also judge what impact it may have on the individual's own image pattern once it is realized. Reason is not only to vent psychological energy, so that life impulses can be properly satisfied, but also to prevent problems before they happen, avoid the pain caused by improper behavior, and bring regrets and regrets to yourself. This makes reason often have to be cautious in some cases, control the impulse of life and adapt itself to the requirements of the external environment. For example, in the process of human activities, people always consume energy gradually. If it is not replenished in time, the normal state of human beings will be destroyed. In the form of need, the body feels that it lacks some biological substances ("hunger"), and when individuals need it, they will have an anxious state. When individuals enter the surrounding environment with objects that meet their needs, they may not immediately realize a purpose to meet this demand. Because of some technical, moral or other obstacles (for example, fruits can't be picked on tall trees, or fruits belong to others, or they can't be picked casually, or they have just been sprayed with pesticides, and it will take several days to pick them, etc. ), individuals may not be allowed to complete this action. Emotion definitely precedes reason. Instinct is absolutely limited to reflection. If emotion represents Yu's hope and passion, then rationality symbolizes rationality and philosophy. Emotion and reason complement each other, and people can't be immune. Emotion-driven activities always tend to endless difficulties and death; Only by flying into the realm of reason can we point to infinite perfection and eternity. Emotion uses reason to get rid of poverty; Driven by emotion, rationality realizes its own image mode to be centered and upright, thus becoming perfect and beautiful. People with relatively special rationality are far more rational than ordinary people. But there is no absolute rational person. People can't have no feelings. With feelings, there will be feelings. "
