La publication des Quodlibets du franciscain Richard de Mediavilla (vers 1248-vers 1300) prend la suite de celle des ses Questions disputées et s'impose, en raison de la richesse dense de ces textes et des circonstances de leur rédaction.

Commentaries on Aristotle's writings have been produced since the 2nd century AD. This edition contains Greek commentaries on his work from the 3rd to the 8th centuries AD by, among others, Alexander of Aphrodiensias, Themistios, Joh. Philoponus, Simplicius in Greek.

In this essay, the structure and content of theiones, a mid-thirteenthcentury collection of sophismata ascribed to a ‘Magister Ricardus’, are described. It is then argued that the text of the Abstractiones itself together with its “descendant” works present us with a case of textual evolution: the main text appears itself to be the result of patchwork and development, with each manuscript in effect a variation of the work; the descendant works continue the job of modifying the text, now so (...) selectively and radically that they can no longer be described as versions of the Abstractiones itself.

Thomas Bradwardine's solution to the semantic paradoxes, presented in his Insolubilia written in Oxford in the early 1320s, turns on two main principles: that a proposition is true only if things are wholly as it signifies; and that signification is closed under consequence. After exploring the background in Walter Burley's account of the signification of propositions, the question is considered of the extent to which Bradwardine's theory is compatible with the distribution of truth over conjunction, disjunction, negation and the conditional.
