Stoics and Sceptics distinguish belief (doxa) from a representationally and functionally similar but sub-doxastic state: passive yielding to appearance. Belief requires active assent to appearances, that is, affirmation of the appearances as true. I trace the roots of this view to Plato's accounts of doxa in the Republic and Theaetetus. In the Republic, eikasia and pistis (imaging and conviction) are distinguished by their objects, appearances versus ordinary objects; in the Theaetetus, perception and doxa are distinguished by their objects, proper perceptibles (...) versus ‘commons’, including being. But underlying these ontological distinctions is a psychological one: the lower mental states are confined to their lower objects because they are passive; the higher mental states have access to higher objects because they result from questioning appearances and making active affirmations about how things are. This doctrine of doxa anticipates both the Hellenistic one and modern accounts of belief as ‘aiming at truth’; it also shows Plato's views of doxa to have more in their favour philosophically and to cohere better with one another than generally thought.

In Republic 4, Plato’s Socrates argues that there are three elements in the soul: the rational, the spirited, and the appetitive. This paper focuses on the argument distinguishing spirit from appetite in the story of Leontius. I shall argue that the rational element first opposes Leontius’ appetite and, when appetite overpowers reason, then Leontius’ spirited part opposes the appetitive. Consequently, there is a kind of disgust that would be appropriately characterized as rational; and, drawing on this consequence, I suggest that (...) the primary target of early ethical education is the rational element of the soul.

Broadly speaking, something can be called intermediate for Plato insofar as it occupies a place between two objects, poles, places, time, or principles. But this broad meaning of the intermediate has been eclipsed by the Aristotelian critique of the intermediate objects of the dianoia, so that it has become more difficult to think of the intermediates as functions of the soul. The aim of this paper is to show how, in the Republic, thumos is analogously treated as an intermediate with (...) other kinds of intermediate objects, and tentatively to relate this psychological intermediate in a broader theory with doxa, as its epistemological ground in the course of action.

This article offers a new formulation of the Socratic principle known as the Principle of the Sovereignty of Virtue. It is divided in three sections. In the first section I criticize Vlastos’ formulation of the PSV. In the second section I present the weighing model of practical deliberation, introduce the concepts of reason for action, simple reason, sufficient reason and conclusive reason that were offered by Thomas Scanlon in Being realistic about reasons, and then I adapt these concepts so as (...) to render them apt to be used in the formulation I intend to offer. In the third section I present my formulation of the PSV using the concepts introduced in the second section and explain why I believe this formulation is better than the one offered by Vlastos.

El avance de los estudios sobre filosofías socráticas ha permitido una vuelta renovada al examen de pasajes intertextuales en el corpus platónico. El presente trabajo explora pasaje del sueño de Teeteto, 201c ss. y sus vínculos con la filosofía antisténica. En primer lugar, analiza las características de esta obra en el contexto del diálogo socrático. En segundo lugar, traza las coordenadas exegéticas del pasaje del sueño, y finalmente, ofrece una interpretación de la filosofía antisténica que revela contactos relevantes con el (...) planteo platónico. Por esta vía, se despliega una hipótesis sobre el sentido general del diálogo y su modo de comprender el fenómeno del conocimiento. (shrink)

Plato gives us two model philosophical figures, apparently in contrast with each other—one is the otherworldly philosopher who sees truth and reality outside the cave and has the knowledge to rule authoritatively within it; the other is the demotic figure of Socrates, who insists that he does not know but only asks questions. I consider Plato’s contrasting idioms of seeing and asking or talking, and argue that the rich account of perception that is represented in the Republic requires both idioms, (...) and both models, to explain the development of epistemic virtue. Furthermore, the conditions he places on the giving and taking of reasons show how Plato takes intellectual virtue to be inseparable from moral virtue. That integrated picture of virtue may—however disposed we may be towards the role of virtue in either ethics or epistemology—have something to say to us about how philosophy might best be carried on.

In modern epistemology, one ‘value of knowledge’ problem concerns the question why knowledge should be valued more highly than mere true belief. Though this problem has a background in Plato, the present paper, focused on Philebus 55–9, is concerned with a different question: what questions might one ask about the value of knowledge, and what question does Plato ask here? The paper aims to articulate the kind of value Plato here attributes to ‘useless’ knowledge, knowledge pursued without practical object; and (...) why, according to him, there is value in being a knower. Though his answer to this question requires commitments we may resist, it has a structure of general philosophical interest. (shrink)

Desperately difficult texts inevitably elicit desperate hermeneutical measures. Aristotle's De Anima, book three, chapter five, is evidently one such text. At least since the time of Alexander of Aphrodisias, scholars have felt compelled to draw some remarkable conclusions regarding Aristotle's brief remarks in this passage regarding intellect. One such claim is that in chapter five, Aristotle introduces a second intellect, the so-called 'agent intellect', an intellect distinct from the 'passive intellect', the supposed focus of discussion up until this passage.1 This (...) view is a direct descendent of the view of Alexander himself, who identified the agent intellect with the divine intellect.2 Even the staunchest defender of such a view is typically at a loss to give a plausible explanation of why the divine intellect pops into and then out of the picture in the intense and closely argued discussion of the human intellect that goes from chapter four through to the end of chapter seven.3 Revolting against an extravagant postulation of entities, Michael Wedin, for example, has argued with considerable subtlety and ingenuity that there is in fact only one intellect discussed in De Anima.4 This unified intellect is fully capable of being integrated into Aristotle's hylomorphic psychology. In order to make his case, though, Wedin is himself forced (1) to discount the importance of some texts and (2) to interpret others in a way that strains credulity. (shrink)

In this paper, I explore the origins of the ‘problem of universals’. I argue that the problem has come to be badly formulated and that consideration of it has been impeded by falsely supposing that Platonic Forms were ever intended as an alternative to Aristotelian universals. In fact, the role that Forms are supposed by Plato to fulfill is independent of the function of a universal. I briefly consider the gradual mutation of the problem in the Academy, in Alexander of (...) Aphrodisias, and among some of the major Neoplatonic commentators on Aristotle, including Porphyry and Boethius. (shrink)

One of Plato’s central tenets is that we can know forms. In Parmenides 133b4–134b5, Plato presents an argument whose sceptical conclusion is that we can’t know forms. Although he indicates that the argument doesn’t succeed, he also says it’s difficult to explain how it fails. Commentators have suggested a variety of flaws. I argue that the argument can be defended against some, though not all, of the alleged flaws. But I also argue that Plato hints at a crucial distinction that (...) hasn’t been brought to bear in this context, and that indeed he is sometimes thought not to draw: that between the content and object of knowledge. Once we are clear about this distinction, we can see that the sceptical argument doesn’t imply that we can’t know forms. (shrink)
