"...A paradox is a statement or group of statements that lead to a contradiction or a situation which (if true) defies logic or reason, similar to circular reasoning. Typically, however, quoted paradoxical statements do not imply a real contradiction and the puzzling results can be rectified by demonstrating that one or more of the premises themselves are not really true, a play on words, faulty and/or cannot all be true together..." wikipedia
