1. Rationality means that people are confident and brave in their normal state of thinking, do not panic when encountering things, can fully understand and summarize, analyze as soon as possible, and then properly use one of various plans (these plans can be preparatory or temporary) to operate or handle, so as to achieve the expected effect of the event. Rationality is behavior based on the results of normal thinking. On the contrary, it is irrational. The significance of rationality lies in being responsible for one's own existence and social mission of transcending oneself.
2. First, sensibility is understood as the opposite of rationality. When "sensibility" is compared with "rationality", it becomes "irrationality", sensibility and sentimentality. Everyone's understanding of "rationality", even if not accurate, will not deviate too much, but the understanding of "sensibility" will vary greatly. It is the biggest prejudice and misunderstanding of "sensibility" to think that sensibility is irrational and perceptual. The emotional color of the word "sensibility" is not a very negative derogatory word.
