Neste trabalho argumento que o Teeteto é um diálogo sobre a relação entre o conceito de razão, entendido como uma potência específica da alma, e a sensação, compreendida como um processo inconsciente do corpo. No primeiro capítulo examino a análise platônica da epistemologia protagoreana. Tento mostrar que nesta seção Platão não está argumentando uma tese platônica sobre o mundo sensível. Ele está explicando e criticando os princípios fundamentais da epistemologia protagoreana. No final da seção Platão explica a distinção entre razão e sensação. Na análise da segunda parte defendo que a massa de argumentos dessa seção formula uma tese platônica sobre a essência do conhecimento. Por fim, no comentário da terceira definição examino o conceito de logos da teoria do sonho e o significado da tese de que os elementos são perceptíveis. / In this work I argue that the Theaetetus is a dialogue about the relation between the concept of reason, understood as a kind of power of the mind, and perception, viewed as an unconscious process of the body. In the first chapter I examine Platos analysis of Protagorean epistemology. I try to show that in this section Plato is not arguing his own view about the sensible world. He is, rather, explaining and criticizing the fundamental principles of the protagorean epistemology. At the end of this section Plato explains the distinction between reason and perception. In my analysis of the second part, I argue that the mass of arguments of this section formulates a platonic thesis about the essence of knowledge. Finally, in my commentary of the third definition, I examine Dreams concept of logos and the meaning of the thesis that the elements are perceivable.

Plato and Aristotle both believe that in ideal circumstances the best form of government obtains when virtuous and knowledgeable people rule. But surprisingly, alongside their well-known views in ideal political philosophy, they also have rich and complex views on non-ideal political philosophy, and these views turn out to be deeply conservative. In the Statesman, Laws, and Politics, Plato and Aristotle recognize stability problems generated by non-ideal circumstances. Specifically, their views on the law’s role in habituation of character, and habituation’s role in ensuring the authority of the law lead them to think that the high costs of changing the existing legislation and constitutional arrangements normally outweigh the benefits gained.

Thesis advisor: Marina McCoy / If Plato’s dialogues offer recollection as a paradigm for human knowing, then, forgetfulness as the opposite of recollection, would seem to be ignorance, or the destruction of knowing. However, forgetfulness is not simply recollection’s opposite, but it also serves as its precondition; to recollect something, one must first forget it. Forgetfulness involves an absence that may re-present itself. This dual nature of forgetfulness as, on the one hand, a precondition for philosophical recollection and, on the other, characteristic of ignorance and destruction of knowledge, mirrors the experience of perplexity (ἀπορία), which can serve either as the impetus for philosophical inquiry or as the ground to foreclose any further questioning. My dissertation considers the implications of forgetting, foresight, and oversight, in Plato's Protagoras as a new way to shed light on the relationship and difference between the sophist and philosopher. I propose that both philosophy and Protagorean sophistry understand something about the nature and limits of human understanding in light of our tendency to forget. Protagorean sophistry, however, attempts to overcome human limits in its aim at perfect foresight. Protagoras ultimately capitulates to ἀπορία by refusing to inquire earnestly, thereby avoiding the problem posed by our tendency to forget. Socratic philosophy, on the other hand, cultivates and maintains ἀπορία in its recognition that forgetting is a limitation that is at once intrinsic to human understanding and the necessary occasion for learning that underlies all philosophical inquiry. Socratic foresight, in opposition to Protagorean foresight, is characterized by its recognition that ἀπορία and oversight are persistent and unavoidable conditions of all human inquiry. Rather than attempt to overcome human nature either by capitulating to or resolving ἀπορία in a definitive answer, Socratic philosophy is depicted as an aporetic way of living, which thus remains open to what is yet to be known. In this way, Socratic foresight comes to light as superior to that of Protagorean sophistry both in its self-knowledge and in its implicit affirmation of what would otherwise seem to be a mere weakness in human nature. Socratic foresight welcomes ἀπορία as the condition for all human inquiry and achievement. / Thesis (PhD) — Boston College, 2023. / Submitted to: Boston College.

In this thesis, I identify and engage an orthodox view in Aristotelian scholarship. Many scholars maintain that Aristotle, in the third book of his Nicomachean Ethics, claims that we should always blame people who act badly with ignorance of what is moral. This view, which I label the “common view” is widespread and unquestioned in the literature. I disagree with the orthodox view, and maintain that we can read Aristotle as not always holding people who act badly in ignorance of what is moral as blameworthy. There are three essential steps in my argument. First, I show that it is not certain that Aristotle commits himself to the common view in the passages usually cited as evidence for the view. I review the evidence in favor of the common view, and argue that other interpretations of Aristotle are equally compatible with his text. Second, I argue that there is textual evidence elsewhere in the Nicomachean Ethics which is contrary to the common view. Thirdly and finally, I suggest that an alternate reading – on which Aristotle allows for pardon in some cases where people act badly in ignorance of what is moral – chimes well with other portions of his ethics, and with scholarly literature: I take two such cases, moral education and ethical deliberation. Given the evidence against the common view, and the evidence in favor of an alternate reading, I suggest that the orthodox view should be abandoned by scholars. / Thesis / Doctor of Philosophy (PhD) / In this thesis I identify and engage an orthodox view in Aristotelian scholarship.

This view, which I label the “common view” is widespread and unquestioned by scholars. I disagree with this reading of Aristotle. I do not think that Aristotle commits himself to this view in his writings. Moreover, I argue that the common view is a bad fit with other passages from the Nicomachean Ethics. If the common view is false, as I claim, it is important for us to formulate an alternate reading of Aristotle’s comments. I proffer one such reading, a reading on which people are not always worthy of blame when they act badly in ignorance of what is moral.

In this thesis, I argue that the ethical theory Plato develops in the Republic assigns critical importance to the role of one’s moral dispositions in their ability to make progress in philosophy. On this view, cultivating a good character, although not sufficient for pursuing philosophy, is necessary for success in philosophic endeavor. Conversely, having a vicious character precludes one from being able to acquire wisdom, which is the goal of philosophy. This is in contrast to Socratic intellectualism, which Plato is commonly seen to have adhered to in his earlier writings. The intellectualist view holds that knowledge is sufficient for virtue, and so one naturally becomes virtuous through the acquisition of wisdom. In other words, rather than virtuous character being necessary for philosophy, it is merely an effect of becoming wise. I argue that Plato moderates this kind of intellectualism in Republic in a way that makes the relationship between moral virtue and wisdom bidirectional. I demonstrate the plausibility of this thesis by examining an array of themes in the Republic, starting with the nature of philosophy and what it means to be a philosopher, and concluding with a look at the theory of education Plato advances throughout the dialogue. / Thesis / Master of Philosophy (MA)

In this thesis I attempt to bring out some interesting implications of Plato’s political thought as it is presented in the Politicus. In particular, I will show how this dialogue provides a new picture of the relation between ruler and ruled; a picture that stresses the importance and responsibility of every citizen, not just of the statesman himself. This is achieved by an analysis of the notion of political craftsmanship envisaged by the main speaker of the dialogue, the Eleatic Stranger. However, before I turn to consider the Politicus itself, I provide a brief presentation of another Platonic craftsman, the demiurge of the Timaeus. As will be clear, the teleological structure, and the accompanying terminology, of his craftsmanship will mirror that of the true statesman and thus help us understand the latter’s political rule. My choice to focus on this aspect of the Politicus is motivated by the text itself. For the question of the kind of craftsmanship involved in political rule is picturesquely, yet effectively, brought to the fore by the myth in the early parts of the dialogue, which distinguishes between two rival conceptions and associates the statesman with one of them. I conclude by reflecting on the significance of my findings for Plato’s political thought as a whole.

Thesis advisor: Marina B. McCoy / This dissertation investigates the role that eros in general, and philosophical eros in particular, plays in the search for the eidos of the beautiful in Plato’s Hippias Major. It defends the claim that noesis of the eidos of the beautiful can only be accomplished within the life of philosophical eros, that is, within the life of eros which is directed toward the good. As such this dissertation aims both to provide an interpretive key to the Hippias Major, allowing us to read the dialogue in a rich and novel way, and also to make the claim that the Hippias Major presents us with a picture of the interrelation between eros, philosophy, and beauty, and about how these three elements manifest themselves in human life. As such, some continuities and parallels can be found between it and the other two dialogues which deal most explicitly with beauty and eros, the Phaedrus and Symposium. The first five chapters interpret a particular section of the Hippias Major according to role the eros plays within it, attempting to show that eros, both in general and in its unique manifestation as philosophical eros, is a crucial mediating term for any comprehensive understanding of any section of the dialogue, and therefore of the dialogue as a whole. In each of these five chapters, I will articulate the role that eros plays within the search for obtaining a noetic glance at the eidos of the beautiful. The first chapter demonstrates how Socrates’s philosophical eros gives birth to the question about the beautiful itself within the context of a discussion about sophistry and money. The second chapter shows how Socrates’s philosophical engagement with Hippias’s definitions of the eidos of the beautiful generates a dialectic of ascent, allowing Hippias to expand his understanding of what counts as beautiful in a trajectory that mirrors Diotima’s ascent in the Symposium. The third chapter articulates the erotic significance of Socrates’s claim that the eidos of the beautiful inheres in being and not appearances. The fourth chapter gauges the erotic significance of Socrates’s and Hippias’s claim that the beautiful is good, and the good beautiful. The fifth chapter interprets the comic and tragic aspects of the dialogue in terms of philosophical eros, its rejection and fulfillment. The sixth chapter will take stock of the overall interpretation of the Hippias Major developed in the first five chapters, and will present the overarching view about the relationship between the contemplation of beauty, on the one hand, and desire for possession of beauty and moral concern, on the other, which one can glean from the character and action of Socrates in Hippias Major. It will bring this view into a conversation with the notion of “liking devoid of interest” which is found in Kant’s Critique of Judgment. The conclusion of this dissertation will underscore the principle claim, that the philosophical search for the eidos of the beautiful can neither be separated from the eros which beauty inspires in a human being, nor can it be accomplished without one’s eros benig directed toward the good, and that this philosophical search is marked by suffering and possible tragedy. / Thesis (PhD) — Boston College, 2015. / Submitted to: Boston College.

O objetivo deste trabalho está relacionado à questão de saber qual a natureza da virtude em Platão; para tanto, procuramos demonstrar que a virtude na ética platônica possui diferentes fases. A primeira, trata da virtude a partir da visão socrática, considerada a fase de juventude de Platão; nesta fase, o conceito de virtude coincide com conhecimento, ou seja, todo princípio ético deve estar fundamentado pela razão, portanto o conhecimento é o princípio fundamental e unificador de todas as virtudes. Na segunda fase, o conhecimento continua sendo o princípio unificador, no entanto, o conceito de virtude se evidencia como uma unidade que se harmoniza pelo pressuposto das diferenças, isto é, Platão faz emergir a ação, o conflito, conseqüentemente isto leva à superação do intelectualismo socrático, no sentido de mostrar que o conhecimento é necessário, mas não suficiente para unificar as virtudes. E por último, temos a questão do ensino da virtude a partir do diálogo Mênon. Embora o citado diálogo negue a possibilidade do ensino da virtude, entretanto deixa em aberto a mesma possibilidade no que diz respeito à natureza da virtude ser ensinável. / The objective of this paper concerns the question of knowing what the nature of virtue in Plato is. In order to achieve it, we aim to demonstrate that the virtue in the platonic ethics has different phases. The first one deals with virtue from the socratic vision, known as the phase of Plato\'s youth; in which the concept of virtue coincides with knowledge, that is, all ethical principles must be based on reason, therefore knowledge is the basic and unifying principle of all virtues. In the second phase, in spite of the fact that knowledge is still regarded as the unifying principle, the concept of virtue is evidenced as a unit that is harmonized through the assumption of differences, that is, Plato makes the action and the conflict emerge, which consequently leads to the overcoming of the socratic intellectualism, in that it shows that `knowledge is necessary, but not enough to unify the virtues. Finally, there is the question of the teaching of virtue from the Menon dialogue. Although the aforementioned dialogue denies the possibility of the teaching of virtue, yhe same possibility concerning the nature of the teaching of virtue remains unresolved.

Thesis advisor: Marina McCoy / In Aristotle's Nicomachean Ethics, the project of developing virtue and of being virtuous is always realized in one's immediate, particular circumstances. Given that perception is the faculty that gains access to the particular, Aristotle seems to afford perception a central role in ethical life. Yet Aristotle does not provide an account of ethical perception: he does not explain how the perceptual faculty is able grasp ethically relevant facts and how the perceptual capacity can do so well, nor does he explain the manner in which perception influences ethical decisions and actions. It is the project of this dissertation to provide such accounts. There are two main difficulties in the notion of ethical perception in Aristotle's thought: first, perception appears ill-suited to ethical life because the objects of perception are always perceived with respect to the individual's subjective condition--her desires, fears, etc. The information relayed by perception is always relative to the perceiver, i.e. merely the apparent good. Second, virtue is the excellence of the rational soul, while perception is a faculty shared by non-rational animals. It appears, then, that perception must be limited to playing an instrumental role in ethical reasoning and action. This dissertation addresses these difficulties by developing an account of uniquely human perception that is influenced and informed by the intellectual element of the soul. I argue that the project of ethical development, for Aristotle, is the project of integrating one's perceptual faculty with the intellectual capacity, such that one's perception transcends the natural relativity to the perceiver and gains access to the true good as it emerges in one's particular situation. / Thesis (PhD) — Boston College, 2013. / Submitted to: Boston College.

Esta dissertação tem dois objetivos principais: (i) apresentar um estudo introdutório e (ii) uma tradução integral do Eutífron de Platão. O Eutífron é um diálogo de definição. Nesta obra, Sócrates quer saber o que é o piedoso. Enquanto pergunta, examina e refuta as respostas de seu interlocutor, o filósofo também fornece um conjunto de instruções sobre como entender e responder a sua pergunta. Essas instruções podem ser entendidas como exigências ou requerimentos socráticos. O nosso estudo tentará identificar, prioritariamente, (i) o conjunto de exigências que acompanham a pergunta o que é o piedoso? e (ii) algum procedimento socrático específico que visa definir o piedoso. Quanto à tradução, utilizaremos a edição recente de E. A. Duke, W. F. Hicken, W. S. M. Nicoll, D. B. Robinson e J. C. G. Strachan (Oxford Classical Texts, 1995), que substitui a edição canônica de John Burnet na mesma coleção (Oxford Classical Texts, 1903). / This dissertation has two main objectives: (i) present an introductory study and (ii) an integral translation of Platos Eutífron. The Eutífron is a dialogue of definition. In this work, Socrates wants to know what the pious is. While asks, examines and refutes the answers of his interlocutor, the philosopher also provides a set of instructions about how to understand and to answer his question. These instructions may be understood as socratic exigencies or requirements. Our study aims to try to identify, prioritarily, (i) the set of exigencies that follows the question what is the pious? and (ii) any specific socratic procedure that intends to define the pious. Concerning the translation, we will use the recent edition of E. A. Duke, W. F. Hicken, W. S. M. Nicoll, D. B. Robinson e J. C. G. Strachan (Oxford Classical Texts, 1995), that replaces the canonic edition of John Burnet of the same collection (Oxford Classical Texts, 1903).
