Paradox is rooted in the limitations of intellectual knowledge, intellectual logic (traditional logic) and contradictory logic. The root cause of paradox is to formalize traditional logic and absolutize its universality, that is, to regard formal logic as a way of thinking.
Paradox is the confusion of facts and values in different levels of thinking, meaning (content) and expression (form), subjectivity and objectivity, subject and object, proposition or reasoning, and the asymmetry of thinking content and thinking form, thinking subject and thinking object, thinking level and thinking object, thinking structure and logical structure.

The extension of paradox:
Zhi Nuo, an ancient Greek mathematician who was later than Pythagoras, once put forward some famous paradoxes, which had an important influence on the concepts of mathematics and physics in later generations. Achilles paradox is one of them.
Achilles is a running hero in Greek mythology. Zhi Nuo said: Achilles couldn't catch up with the tortoise slightly ahead of him in the race, because when he reached the starting point of the tortoise, the tortoise crawled forward again. The distance between Achilles and the tortoise can be narrowed infinitely, but it will never catch up with the tortoise.
Mr. Fang Lizhi once described this problem in physical language: two different time measures are used in Achilles paradox. The general measurement method is: suppose that the distance between Achilles and tortoise is s at first, and the speed is V 1 and V2 respectively. When the time is t = s/(V 1-V2), Achilles catches up with the tortoise.
