What is contradiction in philosophy? Contradictions exist in everything. In case: I want to eat. How to find this contradiction?

Philosophical contradiction refers to things that are inconsistent with the interests or wishes of human beings (such as themselves, others and society) and their relations. As for whether things are contradictory or conflicting, it is always based on "people's interests and wishes." If the reference frame of human survival and development or better survival and development is lost or removed, then everything in the universe is harmonious (existence is reasonable), so there is no contradiction, no contradiction.

For example, "I'm going to eat" does not cause others to have no food, or does not cause any other damage or adverse effects to others, so it does not involve contradictions. However, if you want to eat when food is very tight and scarce, it may cause others or pets to have no food, which will cause conflicts between you and others and dogs.
