Abstract

This article is focused on the concept of logic in Avicenna’s Isagoge, a text which had great impact both on Arabic and Western thought. Its main section is devoted to an investigation of Avicenna’s clarification of the nature of logic, its proper subject matter as well as its place within the canon of the philosophical sciences. In this connection, special attention is given to Avicenna’s use of the concepts ‘art’ and ‘science’. Significantly, he regards logic as both a science and an art, and argues that in the latter sense, logic is an instrument for the philosophical sciences. Because Avicenna’s Isagoge was read in the Latin West for several centuries, his ideas on the nature of logic played a prominent role in the debates at medieval universities and hence were a likely source of the distinction between ‘logica utens’ and ‘logica docens’.
