Aristotle's iTopicsi is a handbook for dialectic, i.e. the exercise for philosophical debates between a questioner and a respondent. Alexander takes the iTopics ias a sort of handbook teaching how to defend and how attack any philosophical claim against philosophical adversaries. In book 3, Aristotle develops strategies for arguing about comparative claims, in which properties are said to belong to subjects to a greater, lesser, or equal degree. Aristotle illustrates the different argumentative patterns that can be used to establish or refute a comparative claim through one single example whether something is more or less or equally to be chosen or to be avoided than something else. In his commentary on iTopicsi 3, here translated for the first time into English, Alexander of Aphrodisias spells out Aristotle's text by referring to issues and examples from debates with other philosophical school especially the Stoics of his time. The commentary provides new evidence for Alexander's view
