Buridan e as proposições de futuro contingente.

The Medieval philosopher John Buridan (14th century) develops a complex semantics based on the distinction between context of utterance and context of evaluation in order to establish the truth conditions of propositions. This article intends to analyze this semantics and, in particular, to understand its consequences concerning future contingent propositions. This article states that the distinction between context of utterance and context of evaluation results in a satisfactory approach of the truth conditions of future contingent propositions. The approach is considered satisfactory because it avoids, on the one hand, the unpleasant consequences related to the denial of the Principle of Bivalence, and, on the other hand, the attachment to determinism.
