El Origen Platónico de la Mirada

The Platonic Origin of Vision is an investigation into the origins of the Theory of Forms through an analysis of the terms εἶδος and ἰδέα in relation to the search for definition. The aim of this study is to examine the principal passages in which Plato employs εἶδος and ἰδέα to refer to the form or common character shared by a multiplicity, this common character being the fundamental requirement for attaining the definition of a moral term. The central question guiding this research is the following: how does Plato progressively develop a specification of the meaning and application of these terms in the context of the search for definition—that is, the search for a unified discourse as opposed to the enumeration of examples characteristic of a multiplicity of cases? To address this question, the study focuses on three dialogues: Euthyphro (5d1–4), Meno (72c), and Cratylus (389b). Together, these texts constitute the backbone of the thesis. The Platonic Origin of Vision examines the scope and significance of these terms within the selected dialogues, exploring how the search for the definition of piety in the Euthyphro marks the beginning of a problem that Plato further develops in the Meno and which, in our view, reaches a decisive stage in the Cratylus. Specifically, this study concerns the thematization of εἶδος and ἰδέα as a path leading, through the opposition between the common character and multiplicity, toward the distinction between doxa and epistēmē. Drawing upon the three passages mentioned above, this investigation is devoted to the study of Plato’s reflection on the common character: namely, how and why Platonic thought develops an increasing concern with deepening the distinction between directing one’s attention toward the common character shared by a multiplicity of actions (as in the Euthyphro and Meno) and the determination of this same character in the Cratylus, where the shuttle itself is distinguished from particular shuttles. In other words, this thesis studies how Platonic thought progressively specifies the distinction between the search for definition (the search for the common character) and sensible reality, understood as the realm subject to motion and change and, for that very reason, impossible to know in a strict sense.
