Truth and Falsity in Buridan's Bridge

This paper revisits Buridan's Bridge paradox (Sophismata, chapter 8, Sophism 17), itself close kin to the Liar paradox, a version of which also appears in Bradwardine's Insolubilia. Prompted by the occurrence of the paradox in Cervantes's Don Quixote, I discuss and compare four distinct solutions to the problem, namely Bradwardine's "just false" conception, Buridan's "contingently true/false" theory, Cervantes's "both true and false" view, and then Jacquette's "neither true simpliciter nor false simpliciter" account. All have in common to accept that the Bridge expresses a truth-apt proposition, but only the latter three endorse the transparency of truth. Against some previous commentaries I first show that Buridan's solution is fully compliant with an account of the paradox within classical logic. I then show that Cervantes's insights, as well as Jacquette's treatment, are both supportive of a dialetheist account, and Jacquette's in particular of the strict-tolerant account of truth. I defend dialetheist intuitions (whether in LP or ST guise) against two objections: one concerning the future, the other concerning the alleged simplicity of the Bridge compared to the Liar.
