Points in Logic by Ibn-Sina: Critical Edition and Introduction

Here I present a critical edition of one of Ibn Sina`s short treatises containing subtle points in logic. So far only half of it, which is not devoid of errors, has been published in the margins of Mulla Sadra`s commentary on the book: al-Ĕidåya al-Athìriyya, in the lithographic edition. My critical edition is based on three manuscripts from the libraries of Istanbul and a manuscript from the Senate House of Iran library (Majles-e-Sena), in addition to the above mentioned incomplete lithographic edition. Some of the features of this treatise in contrast to IbnSina`s other logical writings are: the priority given to 'assertion' (taģdìq) over 'conception' (taģawwur); a brief but comprehensive classification of the four human faculties; a different definition for 'proposition'; and the classification of propositions into 'predicative', 'connective' and 'disjunctive', without mentioning the conditional. Furthermore, it should be noted that in this treatise singular propositions are confined to predicative ones.
