Plato's Epistemology presents an original interpretation of one of the central topics in Plato's work: epistemology. Moss argues, against the grain of much modern scholarship, that Plato's epistemology is radically different from our own.

It is widely held by commentators that in the Protagoras, Socrates attempts to explain the experience of mental conflict and weakness of the will without positing the existence of irrational desires, or desires that arise independently of, and so can conflict with, our reasoned conception of the good. In this essay, I challenge this commonly held line of thought. I argue that Socrates has a unique conception of an irrational desire, one which allows him to explain the experience of mental (...) conflict and weakness of the will, while still holding the Socratic thesis that we always do what we think is good. The resulting picture is both psychologically plausible and philosophically distinctive. (shrink)

Vice epistemology is the philosophical study of the nature, identity, and epistemological significance of intellectual vices. Such vices include gullibility, dogmatism, prejudice, closed-mindedness, and negligence. These are intellectual character vices, that is, intellectual vices that are also character traits. I ask how the notion of an intellectual character vice should be understood, whether such vices exist, and how they might be epistemologically significant. The proposal is that intellectual character vices are intellectual character traits that impede effective and responsible inquiry. I (...) argue that situationist critiques of virtue epistemology pose no significant threat to this proposal. Studies by social psychologists of belief in conspiracy theories suggest that it is sometimes appropriate to explain questionable beliefs by reference to intellectual character vices. Neither ‘regulative’ nor ‘analytic’ epistemology has any good reason to question the epistemological significance of such vices. (shrink)

In this paper I challenge the commonly held view that Plato acknowledges and accepts the possibility of akrasia in the Laws. I offer a new interpretation of the image of the divine puppet in Book 1 - the passage often read as an account of akratic action -- and I show that it is not intended as an illustration of akrasia at all. Rather, it provides the moral psychological background for the text by illustrating a broader notion of self-rule as (...) a virtuous condition of the soul (and lack of self-rule as a vicious condition). I examine key discussions in the Laws in order to show how Plato makes use of this broader notion of self-rule throughout the dialogue, and I argue that nothing Plato says in the Laws commits him to the possibility of akrasia. One significant consequence of my interpretation of the puppet passage is that it avoids the need to posit developmentalism in Plato's late views about the embodied human soul, as some recent commentators have done: the moral psychology of the Laws, on my reading, is not incompatible with the Republic's tripartite theory of the soul.

In this article, I develop an Aristotelian account of akrasia as a primary failure of intentional agency in contrast to a phenomenon I refer to as ‘ordinary weakness of will’: I argue that ordinary weakness of will is best understood as a secondary failure of intentional agency, that to tackle akrasia.

de Anima III.10 characterizes akrasia as a conflict between phantasia (“imagination”) on one side and rational cognition on the other: the akratic agent is torn between an appetite for what appears good to her phantasia and a rational desire for what her intellect believes good. This entails that akrasia is parallel to certain cases of perceptual illusion. Drawing on Aristotle's discussion of such cases in the de Anima and de Insomniis , I use this parallel to illuminate the difficult discussion (...) of akrasia in Nicomachean Ethics VII.3, arguing that its account of akrasia as involving ignorance is compatible with, and in fact crucially supplements, the more straightforward account we find elsewhere in the corpus of akrasia as a struggle between desires. (shrink)

In trying to explain the possibility of akrasia , it seems plausible to deny that there is a conceptual connection between motivation and evaluation ; akrasia occurs when the agent is motivated to do something that she does not judge to be good . However, it is hard to see how such accounts could respect our intuition that the akratic agent acts freely, or that there is a difference between akrasia and compulsion. It is also hard to see how such (...) accounts could be extended to the realm of theoretical reason, but this is generally not taken Ito be a problem, because it is generally assumed that there is no similar phenomenon in the realm of theoretical reason. This paper argues that there is such a thing as theoretical akrasia, and that we can find a characterization of this phenomenon in Descartes’s Meditations. Drawing on certain passages in the Meditations, we can construct an account of theoretical akrasia; this account can then be adapted to resolve the original problem of akrasia in the realm of practical reason. The account asserts that there is a conceptual connection between motivation and evaluation in free action; it also enables us to show how the akratic agent is still acting freely when he does something that he does not judge to be the best all things considered.

In the Protagoras, Socrates argues that each of the virtue-terms refers to one thing (: 333b4). But in the Laches (190c8–d5, 199e6–7), Socrates claims that courage is a proper part of virtue as a whole, and at Euthyphro 11e7–12e2, Socrates says that piety is a proper part of justice. But A cannot be both identical to B and also a proper part of B – piety cannot be both identical to justice and also a proper part of justice. In this (...) paper we argue that coherent sense can be made of Socrates'' apparently conflicting claims. The key to understanding Socrates'' position, we will argue, is the central role of wisdom among the virtues. It is through the relationship of each virtue to wisdom that each may be said to be the same as all of the others, on the one hand, and also that some virtues may be regarded as proper parts of some other virtues, or as proper parts of virtue in general, on the other.

A careful reading of the initial posing of the issue to be debated with Protagoras and of its subsequent restatement when the debate resumes after a break will show that Socrates employs three distinct formulae, only the first of which answers at all closely to the term "Unity of the Virtues" which has been commonly used in the scholarly literature as a label for the position which Socrates upholds in the debate. The other two formulae, perfectly distinguishable from the first, (...) I shall call the "Similarity" and "Biconditionality" Theses. I shall discuss the three Theses seriatim. But let me emphasize from the start that they are not treated in the text as logically disjoint tenets, but as successive moments in the elucidation of a single doctrine. That is how Protagoras himself understands them. At no point does he try to drive a wedge between them or play off one against another. He accepts them as complementary expressions of a theory which he rejects and combats as a whole. (shrink)

Plato's Utopia Recast is an illuminating reappraisal of Plato's later works, which reveals radical changes in his ethical and political theory. Christopher Bobonich examines later dialogues, with a special emphasis upon the Laws, and argues that in these late works Plato both rethinks and revises the basic ethical and political positions that he held in his better known earlier works, such as the Republic. This book will change our understanding of Plato. His controversial moral and political theory, so influential in (...) Western thought, will henceforth be seen in a new light. (shrink)

Plato links pleasure with illusion, and this link explains his rejection of the view that all desires are rational desires for the good. The Protagoras and Gorgias show connections between pleasure and illusion; the Republic develops these into a psychological theory. One part of the soul is not only prone to illusions, but also incapable of the kind of reasoning that can dispel them. Pleasure appears good; therefore this part of the soul (the appetitive part) desires pleasures qua good but (...) ignores reasoning about what is really good. Hence the new moral psychology of the Republic: not all desires are rational, and thus virtue depends on bringing one's non-rational desires under the control of reason. (shrink)

Plato's Socrates denies that he knows. Yet he frequently claims that he does have certainty and knowledge. How can he avoid contradiction between his general stance about knowledge and his particular claims to have it? Socrates' disavowal of knowledge is central to his defence in the Apology. For here he rebuts the accusation that he teaches – and thus corrupts – the young by telling the jury that he cannot teach just because he knows nothing. Hence his disavowal of knowledge (...) is important to Socrates. Why does he make this claim? And how then can he justify engaging in any philosophical activity at all? (shrink)

For Socrates, the virtues are a kind of knowledge, and the virtues form a unity. Sometimes, Socrates suggests that the virtues are all ‘one and the same’ thing. Other times, he suggests they are ‘parts of a single whole.’ I argue that the ‘what is x?’ question is sophisticated, it gives rise to two distinct kinds of investigations into virtue, a conceptual investigation into the ousia and a psychological investigation into the dunamis, Plato recognized the difference between definitional accounts of (...) the ousia and a psychological accounts of the dunamis, and the distinction between these two investigations can effectively resolve various interpretive puzzles regarding the unity of the virtues. It is argued that the virtues are ‘one and the same’ psychologically, while they are ‘parts of a single whole’ conceptually. (shrink)

In Plato’s Apology, Socrates famously claimed to know nothing. This Socratic claim to ignorance pervades all of Plato’s early dialogues, and it raises many puzzling questions. By working through these puzzles, we can come to understand the figure of Socrates much better, and we can also gain some insight into the nature and purpose of philosophy.
