The contradiction is introduced as follows:

Spear, an attack weapon. Shield: a shield, a defensive weapon. Metaphor is inconsistent with words and deeds.

The contradiction is introduced as follows:

Contradiction reflects a special state in which things interact and influence each other. It is neither a thing nor an entity, but an attribute relationship of things in essence.

This attribute relationship is a special relationship between things, and this special relationship is "opposition". It is precisely because of this "antagonistic" relationship between things that contradictions can be formed. Broadly speaking, if two things must exist when they don't exist, then they are contradictory.

The origin of the contradiction is introduced as follows:

In the 6th century BC, the philosopher epimenides famously said in Park Yung-soo: All Celts are lying.

This sentence is famous because it has no answer. If Epiminides' statement is true, then all Celts are liars, and Epiminides, as a Celtic, is no exception, so what he said should be a lie.

But this contradicts the previous assumption that this statement is true; Assuming that this statement is false, it means that some Cretes are lying, and the Crete Epiminides belongs to the lying part.

The omnipotence paradox began in the Middle Ages, because in the Christian doctrine, the supreme God is "all-powerful, all-knowing and all-good", so it is also called the omnipotence God paradox. The paradox of omniscience and omnipotence is not to deny omniscience and omnipotence or prove that God does not exist, but to point out that the concept of omniscience and omnipotence implies contradictions, and there can be no omniscience and omnipotence God. Even if God exists, it will not be omnipotent.

According to this inference, if this solution really exists, what container should it be in? On the contrary, if there is a container to hold it, it is not a universal solution. Of course, there are some rigorous problems in discussing the paradox of universal solution from the perspective of container, because "the existence of this solution" is not necessarily related to "the existence of the corresponding container to accommodate it"
