The paradox of analysis (or Langford–Moore paradox)[1] is a paradox that concerns how an analysis can be both correct and informative. The problem was formulated by philosopher G. E. Moore in his book Principia Ethica, and first named by C. H. Langford in his article "The Notion of Analysis in Moore's Philosophy" (in The Philosophy of G. E. Moore, edited by Paul Arthur Schilpp, Northwestern University, 1942, pp. 319–342).
