A paradox is a statement that, despite apparently valid reasoning from true premises, leads to a seemingly self-contradictory or logically unacceptable conclusion.
Here are some examples of paradoxes:
* This statement is false. (If the statement is true, then it must be false, and vice versa.)
* The liar's paradox: A person says "I am lying." If they are telling the truth, then they are lying. If they are lying, then they are telling the truth.
* The Barber Paradox: In a village, the barber shaves all men who don't shave themselves. Who shaves the barber?
Paradoxes often involve concepts that are both similar and different, creating a sense of contradiction or absurdity.
