What is a paradox?
A paradox is a statement of conclusion that seems self-contradictory or absurd but is really true. This was classed by philosopher and logician W.V. Quine as a veridical paradox. An example is the adage, “It is better to give than to receive.” It seems obvious that the benefits of receiving inevitably outweigh any possible advantages of giving, but many people find that, contrary to expectations, this is not their experience.
A paradox is a statement that contradicts itself; "`I always lie' is a paradox because if it is true it must be false"
A paradox is an apparently true statement or group of statements that leads to a contradiction or a situation which defies intuition.
