Abstract: This paper discusses the expression, definition, cause and solution of paradox. It involves Russell’s paradox, liar’s paradox, Richard’s paradox, Berry’s paradox, Greering’s paradox, etc., and makes a systematic and thorough analysis of Cantor’s diagonal method, diagonal lemma and Godel’s theorem, which are closely related to the paradox. The paradox of essential implication is also discussed. At the same time, some comments are also made on the gains and losses of related paradoxical literature.
