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.

In his commentary on Aristotle's Physics , Nicole Oresme (c. 1320-1382) propounds a very specific theory of the ontological status of accidents. Characteristic of Oresme's view on accidents is that he does not consider them accidental forms, but only so-called condiciones or modi of the substance. Unlike the term “modus”, the term “condicio” seems to be very characteristic of Oresme's own terminology. Up to now it has been unknown whether Oresme exerted any influence with his condicio-theory of accidents. This paper presents an anonymous 14th-century commentary on Aristotle's Meteorology (Munich, Bayerische Staatsbibliothek, Clm 4375, ff. 19r-46v), in two Questions of which the term “condicio” occurs in an ontological context. Moreover, the text shows further striking coincidences with known works by Oresme, and this makes an influence by Oresme appear all the more probable.

This book is designed to acquaint the reader with C.I. Lewis' ethics by providing critical commentary on Lewis' work in addition to reprinting some of Lewis' writings in ethics. The commentary is not meant to be a substitute for the complete work in ethics that Lewis was preparing before his death but merely a systematic study of some central aspects of his thought in ethics.

The mathematician al-Mahani (9th century AD) is the author of one of the first commentaries on the fifth Book of Euclid's Elements which have been handed down to us. In this commentary, al-Mahani intends to justify Definitions V. 5 and V. 7 of the Elements, which deal with the identity of ratios and with greater ratio, by starting from an anthyphairetic conception of ratio, and by proving the equivalence of the Euclidean and the anthyphairetic points of view. We will try in this paper to describe in detail the content of al-Mahani's commentary, basing ourselves on a thorough examination of most of the extant manuscripts of the Arabic text. The reader will also find in the appendices a mathematical commentary, an English translation, and a critical edition of al-Mahani's commentary.
