This thesis deals with the concept of Socratic-Platonic irony, with emphasis on excerpts in which textual scripts of (eiron) and derivatives are found, which can be understood as ironic occurrences of Plato s Socrates. The problem is that the word (eironeia), in the Attic dialect, generally had the negative semantics of dissembling. However, the ambiguous origin of the term also embraced the idea of questioning. Among the most prominent authors of Greek antiquity, Plato made the most use of eironeia and cognates, most of the time, in contexts where Socrates appears, acting with his very peculiar habit of questioning his interlocutors. Throughout the time, this correlation between the ancient term and the philosophical paradox of the disavowal of knowledge was called Socratic irony. The interpretative currents were divided, basically, between a negative and a positive reading proposal for this event. Therefore, in this thesis, the first and main goal is to scrutinize the relevance of Socratic eironeia/irony, by the verification of the corpus platonicum. Then, we find the eight dialogues that contain instances of the term, subdividing them into those in which (1) the eironeia is not directly related to Socrates, namely, Euthydemus, Cratylus, Sophist and Laws, and others in which (2) the eironeia is directly related to the Platonic protagonist, i.e., Apology, Gorgias, Symposium and Republic. To this end, some basic criteria are organized to help in the delimitation and identification of ironic events, in order to draw more coherent conclusions, regarding the nature and purposes of Socratic eironeia/irony. Furthermore, this thesis has as its second goal the interpretation of Plato s most pregnant literary strategy, namely, the famous anonymity, or concealment of the authorial voice, as a kind of dissimulation, inherent to eironeia. So, we aim to analyze the rhetorical and epistemological potential of this resource, in its two aspects: the Socratic method and the Platonic literary strategy. However, despite the hermeneutical challenges and the controversy that divides the vast critical fortune on the subject, the third goal of this thesis is the approach of positive interpretations or, at least, those which see it as relevant to philosophical practice. Thus, the classics are revisited to think about the present. After all, it is believed that, when Plato employs the Socratic eironeia/irony, the effect of this is the stimulus to reflection on the virtues and on the truth of the various themes found in the dialogues.
