did plato and aristotle have anything to say about belief? The answer to this question might seem blindingly obvious: of course they did. Plato distinguishes belief from knowledge in the Meno, Republic, and Theaetetus, and Aristotle does so in the Posterior Analytics. Plato distinguishes belief from perception in the Theaetetus, and Aristotle does so in the De anima. They talk about the distinction between true and false beliefs, and the ways in which belief can mislead and the ways in which (...) it can steer us aright. Indeed, they make belief a central component of their epistemologies.The view underlying these claims—one so widespread these days as to remain largely unquestioned—is that when Plato and Aristotle talk...

Something Aristotle calls ‘right logos’ plays a crucial role in his theory of virtue. But the meaning of ‘logos’ in this context is notoriously contested. I argue against the standard translation ‘reason’, and—drawing on parallels with Plato’s work, especially the Laws—in favor of its being used to denote what transforms an inferior epistemic state into a superior one: an explanatory account. Thus Aristotelian phronēsis, like his and Plato’s technē and epistēmē, is a matter of grasping explanatory accounts: in this case, (...) accounts that identify the right action and say why it is right. Arguably, Aristotelian rationality is a matter of being able to grasp accounts in general. (shrink)

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.

Aristotle repeatedly claims that character-virtue “makes the goal right“, while Phronesis is responsible for working out how to achieve the goal. Many argue that these claims are misleading: it must be intellect that tells us what ends to pursue. I argue that Aristotle means just what he seems to say: despite putative textual evidence to the contrary, virtue is (a) a wholly non-intellectual state, and (b) responsible for literally supplying the contents of our goals. Furthermore, there are no good textual (...) or philosophical reasons to reject this straightforward interpretation. Contrary to widespread opinion, Aristotle does not characterize Phronesis as supplying ends. Instead, its ethical import lies wholly in its ability to “determine the mean“. Moreover, because character involves non-rational cognition of the end as good, Aristotle can restrict practical intellect to deliberation without abandoning his anti-Humean view that we desire our ends because we find them good.

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)

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.

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.

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.

How does Plato draw the line between perceiving and reasoning? According to Peter Larsen, he gives perception only the power to perceive isolated proper perceptibles, and treats all other cognitive operations as reasoning. I show problems for this interpretation. I argue that in the Republic, non-rational cognition—perception, either on its own, or perhaps augmented by other non-rational powers Plato does not specify, along the lines of Aristotle’s φαντασία —can generate complex cognitions. Reason’s job is not to integrate the raw data (...) of perception into a coherent experience, for we can do that without reason. Instead reason’s job is to question, criticize and correct non-rational experience. I argue that there are grounds for detecting a similar doctrine in the Theaetetus as well. (shrink)
