The theme of this book is interdisciplinary, that is, phenomenology is linked with cognitive science, philosophical theory and the application of science and technology. Frankly speaking, the conclusion of the book is the starting point of the book. During my ten years in Zhejiang University, as a liberal arts student, from time to time, students of science and engineering will ask: What's the use of philosophy? What is the use of phenomenology? Some people think that philosophy is useless, and useless use is for great use. Others say that philosophy is useless. So what? I just want to study this useless thing.

Descartes' dualism of body and mind further developed Plato's contempt for the body. Descartes said: My mind (I am my mind) is completely different from my body and can exist independently of my body. Knowledge is something in the mind. Therefore, if Descartes is right, knowledge cannot be something in the body. This is a key point. Because if body knowledge exists, then the Cartesian way of understanding the body is wrong. In the knowledge model based on Cartesian dualism of body and mind, there is a cognitive subject and a cognitive object, which are separated. Psychological space.
