A paradox is a statement or proposition that seems self-contradictory or logically unacceptable but may nonetheless express a truth. Paradoxes often challenge our understanding of concepts and provoke deeper thought.
Example:
One classic example of a paradox is the statement: "This statement is false."
If the statement is true, then it must be false as it claims. Conversely, if it is false, then it must be true. This creates a logical inconsistency that exemplifies the nature of a paradox.
