What does paradox mean? Please give a simple explanation with examples.
Paradox is: on the surface, the same proposition or reasoning has two opposite conclusions, and both conclusions can be established. The so-called solution of paradox is to find and correct the logical errors in paradox by using symmetrical logical thinking mode.

For example:

A crocodile stole a father's son, and he promised to give him back if his father could guess what he was going to do. If the father guesses that "the crocodile will not return his son to him", it becomes a so-called "paradox": if the crocodile does not return his son, then the father is right, and the crocodile must return the child to the father, otherwise the crocodile will renege; If the crocodile returns his son to him, then the father guessed wrong and the crocodile broke his word again.

Solution:

The crocodile's "how to do" is a state of mind, and the crocodile's "returning the child to the father" is an act. These two stages are connected in time. Similarly, the father guessed that "the crocodile will not return his son to him" was the crocodile's psychological state, and later "the crocodile returned his son to him" was the crocodile's behavior.

My father guessed that the crocodile's psychological state of "not returning his son to himself" was not contradictory to the crocodile's behavior of "returning his son to himself"-it was precisely because my father guessed the crocodile's psychological state of "not returning his son to himself" that the crocodile had to return his son to himself in order to fulfill his promise.

Symmetric logic here makes the content of the language and the object of the language symmetrical by limiting the time range.

Extended data

The abstract formula of paradox is: if event A occurs, it is deduced that it is not A, if it is not A, it is A. Paradox is the confusion of facts and values implied 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.

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 the universality of formal logic, that is, to regard formal logic as a way of thinking. All paradoxes are caused by formal logical thinking mode, which cannot be found, explained or solved.
