Philosophy Lexicon of Arguments

Planet example: the planet example is an example by V.W.O. Quine (Quine, 1953, “From a logical point of view”, Cambridge, MA) From the necessity of the number 9 being odd, it cannot be inferred that the number of planets is necessarily odd even though the number of planets is equal to 9, and the identity 9 = 9 or number of planets = number of planets is necessary. See also opacity, de re, de dicto, necessity, range.
