The Virtue Of Sōphrosunē In Plato’S Gorgias And Phaedrus, Kristian Sheeley

Theses and Dissertations--Philosophy

This dissertation argues that the substantial differences in Plato’s accounts of virtue in the Gorgias and Phaedrus are best understood as adjustments that Socrates makes in order to have the most pedagogically and ethically valuable impact on the different interlocutors (each of which represents universal type of person) with whom he speaks. While Plato has Socrates give arguments about virtue, love, happiness, and so on that are strong when taken on their own, he also depicts Socrates tailoring these arguments with the aim of persuading his interlocutors to pursue a more virtuous life. The central example I focus on is …

The Role Of Sexual Difference In Plato's Timaeus, Mary Cunningham

Theses and Dissertations--Philosophy

My dissertation is a reading of Plato’s Timaeus that centers sexual difference and in particular femininity. I analyze the role of sexual difference in the framing of the dialogue as well as its accounts of body in the first and second discourse and its account of health in the third discourse. I argue that sexual difference, and, in particular, sexual reproduction, serves as a guiding paradigm of Timaeus’ entire project. I argue in each part of my dissertation that various aspects of the Timaeus depend on a certain notion of sexual difference—even aspects which are seemingly causally prior to the …

Being And Structure In Plato’S Sophist, Colin C. Smith

Theses and Dissertations--Philosophy

Being and Structure in Plato’s Sophist is a study of the metaphysical notion of being as it is at play in Plato’s dialogue the Sophist, and the senses in which Plato’s conception of being entails further accounts of ontological structure and goodness. While modern metaphysics primarily concerns existence, ancient metaphysics primarily concerns what grounds what, and in this dissertation I consider the nature and value of Plato’s understanding of being as a notion of ground rather than a principle of existence. I argue that Plato conceives of being in the fundamentally unified sense of participation, which entails a self-and-other …

Interpreting The Republic As A Protreptic Dialogue, Peter Nielson Moore

Theses and Dissertations--Philosophy

Protreptic is a form of rhetoric, textual and oral in form, which exhorts its recipients to reorient their lives both morally and intellectually. Plato frequently portrays Socrates' use of this rhetoric with interlocutors who are enticed by the moral and political views of figures from Athens' intellectual culture. During these conversations Socrates attempts to persuade his interlocutors to reorient their lives in a way that conforms more closely to his own moral and intellectual practice of philosophy. Plato's depiction of protreptic, however, also exerts a protreptic effect on readers of his dialogues. Plato's writing thus performs a dual function, simultaneously …

The Metaphysics Of Personhood In Plato's Dialogues, Daniel T. Sheffler

Theses and Dissertations--Philosophy

While most scholars know, or think they know, what Plato says about the soul, there is less certainty regarding what he says about the self. Some scholars even assert that the ancient Greeks did not possess the concepts of self or person. This dissertation sets out to examine those passages throughout Plato's dialogues that most clearly require some notion of the self or the person, and by doing so to clarify the logical lineaments of these concepts as they existed in fourth century Athens. Because Plato wrote dialogues, I restrict myself to analyzing the concepts of self and person as …

Perception And Judgment In Plato's Theaetetus, Paul Dirado

Theses and Dissertations--Philosophy

I will argue that Plato’s dialogue Theaetetus demonstrates that knowledge is never caused by sense perception. While various kinds of qualities appear to the soul or mind as a result of sense perception—as a result of external bodies impacting with the sense organs—the being (einai or ousia) of these qualities is something different from the mere appearance of the qualities that occurs through the senses. While white colors appear to the soul through vision, perception itself does not reveal that these many appearances are all instances of one white quality. However, I will demonstrate that it is impossible to …

Truth And Falsehood In Plato's Sophist, Michael Oliver Wiitala

Theses and Dissertations--Philosophy

This dissertation is a study of the ontological foundations of true and false speech in Plato’s Sophist. Unlike most contemporary scholarship on the Sophist, my dissertation offers a wholistic account of the dialogue, demonstrating that the ontological theory of the “communing” of forms and the theory of true and false speech later in the dialogue entail one another.

As I interpret it, the account of true and false speech in the Sophist is primarily concerned with true and false speech about the forms. As Plato sees it, we can only make true statements about spatio-temporal beings if it …
