 So far, we have looked at reasons for and against the two premises of the CP argument for Cartesian Skepticism. A different kind of approach to the argument requires some setup. Philosophers routinely distinguish between sentences and the propositions expressed by some of them. Sentences are language-dependent entities whereas propositions are (something like) the informational content of some of those language-dependent entities (see entry on  propositions).  Thus, we distinguish between the proposition that it is raining and the English sentence It is raining. That very same proposition can be expressed by other sentences, such as the Spanish sentence Está lloviendo. Moreover, which proposition a given sentence expresses (if any) can depend on contextual factors—that is to say, the same sentence may express one proposition when produced in a given a context, and a different one when produced in a different context. Thus, when Tomás says that it is raining he expresses the proposition that it is raining in Tucson on May 14, 2019, whereas when Manolo said “Está lloviendo” last week, he expressed the proposition that it was raining in Mar del Plata on May 10, 2019.
