This standard lies in the thing itself. The former doesn't even touch things, and the latter is based on the relationship and connection of things. Sensory knowledge is the relationship between subject and things, while rational knowledge is the relationship between things. But things are the state of achievement, realization or completion. In this world, there is no such thing. Things are concepts invented by human beings to explain the interaction or movement between states. When the state has not yet been formed and completed, but can be obtained as an interactive relationship, nothing can exist at all. So what does the sensory understanding between subject and things see? Not at all. Some of them are purely subjective. This is an understanding of the senses. A rational person refers to the division, way or road that has been completed. The difference, way or truth of completion refers to the relationship or connection of things. Without research, investigation or analogy, the relationship or connection between things is completely impossible. After research, investigation or analogy, a line or boundary constitutes a relationship and connection. Relationships and connections are displayed separately, displayed and compared, so the influence and function of this fluctuation, change or development that constitutes the situation, meteorology and pattern are clearly shown. Form and make a useful object, because space or object exists in this form, so it is called thing or thing, or thing, matter, event, state of affairs, thing and so on. Because of this, in Chinese, things are interpreted as making, managing, ruling or reasoning, while things are interpreted as things, colors, points, harmony, goodness, beauty or something in between. The clarity and clarity of things are in the heart for nature and understanding. Knowledge and understanding are another qualitative substitute for knowledge, thinking, thinking, reason, emotion or love. Reason is another qualitative substitute for things. Of course, rationality is another way of saying that rationality is knowledge itself for the repetition, difference and the same state of things. Philosophy is the study of knowledge. There is nothing but knowledge, which is just another way of saying that things are spiritual. This is the difference between sense and reason in philosophy, and this is also the origin of science.
