  Inspired by an allegedly similar argument of Frege’s, Davidson (1969) argues that the correspondence theory is bankrupt because it cannot avoid the consequence that all true sentences correspond to the same fact: the Big Fact. The argument is based on two crucial assumptions: (i) Logically equivalent sentences can be substituted salva veritate in the context ‘the fact that...’; and (ii) If two singular terms denoting the same thing can be substituted for each other in a given sentence salva veritate, they can still be so substituted if that sentence is embedded within the context ‘the fact that...’. In the version below, the relevant singular terms will be the following: ‘(the x such that x = Diogenes &amp; p)’ and ‘(the x such that x = Diogenes &amp; q)’. Now, assume that a given sentence, s, corresponds to the fact that p; and assume that ‘p’ and ‘q’ are sentences with the same truth-value. We have:
