Boethius' treatise De Hypotheticis Syllogismis provided twelfth-century philosophers with an introduction to the logic of conditional and disjunctive sentences but this work is the only part of the logica vetus which is no longer studied in the twelfth century. In this paper I investigate why interest in Boethius acount of hypothetical syllogisms fell off so quickly. I argue that Boethius' account of compound sentences is not an account of propositions and once a proper notion of propositionality is available the argument forms accepted by Boethius are seen to be incoherent. It was Peter Abaelard who first understood the nature of propositionality and propositional connectives and used this to criticise Boethius' claims in De Hypothetics Syllogismis. In place Boethius' confusion Abaelard offered a simple and correct account of the hypothetical syllogism.

This book offers a brief, accessible introduction to the thought of Boethius. After a survey of Boethius's life and work, Marenbon explicates his theological method, and devotes separate chapters to his arguments about good and evil, fortune, fate and free will, and the problem of divine foreknowledge. Marenbon also traces Boethius's influence on the work of such thinkers as Aquinas and Duns Scotus.

The paper is in three parts, prefaced by general remarks concerning Boethius' logical translations and commentaries: the text of the Peri Hermeneias as known to and commented on by Boethius (and Ammonius); the organizational principles behind Boethius' second commentary on the Peri Hermeneias ; its source(s). One of the main purposes of the last section is to demonstrate that the Peri Hermeneias commentaries of Boethius and Ammonius are, although part of a common tradition, quite independent of one another, and special consideration is given to the question of how Boethius interpreted and shaped the doxographical material concerning Aspasius, Herminus, and Alexander that had been handed down to him by Porphyry.
