The history of thinking about consequences in the Middle Ages divides into three periods. During the first of these, from the eleventh to the middle of the twelfth century, and the second, from then until the beginning of the fourteenth century, the notion of natural consequence played a crucial role in logic, metaphysics, and theology. The first part of this paper traces the development of the theory of natural consequence in Abaelard’s work as the conditional of a connexive logic with an equivalent connexive disjunction and the crisis precipitated by the discovery of inconsistency in this system. The second part considers the accounts of natural consequence given in the thirteenth century as a special case of the standard modal definition of consequence, one for which the principle ex impossibili quidlibet does not hold, in logics in which disjunction is understood extensionally.

William of Ockham and John Buridan provide different accounts of the distinction between formal and material consequences. Some consequences – in particular, enthymemes – that Ockham would classify as formal would be classified as material by Buridan. This paper explains this taxonomical discrepancy. It identifies the root of the discrepancy not in a difference between Ockham’s and Buridan’s notions of propositional hylomorphism but rather in Ockham’s endorsement of relational characterizations of consequences.
William of Ockham和John Buridan对形式结果和物质结果的区别给出了不同的解释。有些结果,特别是推理,奥卡姆认为是正式的,而布里丹认为是物质的。本文对这种分类学上的差异进行了解释。它指出了差异的根源,不在于奥卡姆和布里丹的命题同构概念之间的差异,而在于奥卡姆对结果的关系表征的认可。

This paper summarizes medieval definitions and divisions of consequences and explains the import of the medieval development of the theory of consequence for logic today. It then introduces the various contributions to this special issue of Vivarium on consequences in medieval logic.

With William of Ockham and John Buridan, Walter Burley is often listed as one of the most significant logicians of the medieval period. Nevertheless, Burley’s contributions to medieval logic have received notably less attention than those of either Ockham or Buridan. To help rectify this situation, the author here provides a comprehensive examination of Burley’s account of consequences, first recounting Burley’s enumeration, organization, and division of consequences, with particular attention to the shift from natural and accidental to formal and material consequence, and then locating Burley’s contribution to the theory of consequences in the context of fourteenth-century work on the subject, detailing its relation to the earliest treatises on consequences, then to Ockham and Buridan.
