This thesis has as its main goal to investigate the notion of apatê in Aristotle, with special focus on the notion in argumentative contexts. Thus, the analysis will focus on some of the works by Aristotle dedicated to argumentation, the Topics and the Sophistical Refutations, and it will try to present a general approach on how does apatê work, based on the psychological works, the De Anima and Parva Naturalia. With the aid of a broader scope on the notion of apatê, the investigation will propose an interpretation that defends that apatê is the expression of the incapacity to discriminate objects by a person and that this is fundamentally caused by the lack of experience (apeiria).
