Hobbes's linguistic conventionalism is one of the most obvious themes of his work. But it has not been considered as closely as it should be, given its prominence. I argue that Hobbes reworked quite traditional materials in such a way as to produce a novel doctrine, but that this novelty did not involve him in the implausible claim that issues of scientific truth and proof could be settled simply on the basis of linguistic agreement. Rather, he grounded his conventionalism in the prelinguistic, naturally given experience he called “mental discourse,” and then linked it to the effort to outflank contemporary skepticism. For these reasons, Hobbes's specific form of conventionalism can then be seen to be central both to the limits of his claims and to what he thought could be established with a certainty robust enough to withstand skeptical challenge.

19. It is true enough that in Hobbes, like many other seventeenth century authors, the much more fully developed theories of signification (and supposition) that are to be found in late scholasticism have been replaced by a less complex conception of the problems of logic and language. Many of the changes are helpfully discussed in Ashworth, E. J., “The Eclipse of Medieval Logic,” in Cambridge History of Later Medieval Philosophy, pp. 787–96Google Scholar, and in Lisa Jardine, “H manism and the Teaching of Logic,” ibid., pp. 797–807, and W.
