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...

This paper examines an ancient debate over the rationality of perception. What leads the Stoics to affirm, and the Epicureans to deny, that to form a sense-impression is an activity of reason? The answer, we argue, lies in a disagreement over what is required for epistemic success. For the Stoics, epistemic success consists in believing the right propositions, and only rational states, in virtue of their predicational structure, put us in touch with propositions. Since they identify some sense-impressions as criteria (...) of truth and thus as the basis for epistemic success, the Stoics maintain that sense-impressions must be rational. The Epicureans agree with the Stoics that sense-impressions function as criteria of truth, and also agree broadly on what it means for a state to be rational, but deny that sense-impressions are rational because (1) they think that epistemic success must be supported by a state that is necessarily error-free and (2) accept that rational states can be false. In reconstructing this debate, we refine the standard interpretation of the fundamental difference between Epicurean and Stoic epistemology and also develop parallels with epistemological debates today. One upshot is a more nuanced appreciation of the merits of Epicurean epistemology vis-à-vis the Stoics. (shrink)

abstract: The kataleptic impression—an impression that is, in some special way, “true and such as could not be false”—is at the core of Stoic epistemology. Since Gisela Striker’s groundbreaking work on the criterion of truth, the dominant view among scholars is that the Stoics restricted kataleptic impressions to certain perceptual impressions. I argue that the Stoics in fact countenanced nonperceptual kataleptic impressions and explain how they thought nonperceptual impressions can meet the definition of the kataleptic impression.

Plato in the Meno is standardly interpreted as committed to condition innatism: human beings are born with latent innate states of knowledge. Against this view, Gail Fine has argued for prenatalism: human souls possess knowledge in a disembodied state but lose it upon being embodied. We argue against both views and in favor of content innatism: human beings are born with innate cognitive contents that can be, but do not exist innately in the soul as, the contents of states of (...) knowledge. Content innatism has strong textual support and constitutes a philosophically interesting theory. (shrink)

Recollection is central to the epistemology of Plato’sMeno. After all, the character Socrates claims that recollection is the process whereby embodied human souls bind down true opinions (doxai) and acquire knowledge (epistêmê). This paper examines the exchange between Socrates and Meno’s slave to determine (1) what steps on the path to acquiring knowledge are part of the process of recollection and (2) what is required for a subject to count as having recollected something. I argue that the key to answering (...) these questions is to get clear on the kind of process recollection is supposed to be. In particular, I argue that recollection is a process akin to the kind of process Aristotle calls “changes” (kinêseisor incompleteenergeiai). The key feature of such processes is that they aim at an end beyond themselves and are not complete until that end comes about. In the case of recollection, the end is knowledge, but inferior mental states, such as false opinion, puzzlement (aporia), and true opinion can come about because of a process of recollection without making it the case that the subject has recollected anything. I argue that this interpretation provides a textually supported and philosophically coherent understanding of Socrates’ conception of recollection. (shrink)

In this paper I examine, and reject, one of the chief philosophical arguments that purports to show that Pyrrhonian Skepticism is incompatible with possessing any beliefs. That argument, first put forward by Jonathan Barnes and since accepted by many philosophers, focuses on the skeptic's resolute suspension of judgment concerning one philosophical issue, namely whether criteria of truth exist. In short, the argument holds that, because skeptics suspend judgment whether criteria of truth exist, they have no basis on which to discriminate (...) between their impressions, which is a necessary condition for belief formation. I show that this argument fails because it misunderstands both the nature of criteria of truth and the epistemic consequences of suspending judgment concerning their existence. Thus, I clear the main philosophical obstacle preventing an interpretation of Pyrrhonism as consistent with possessing beliefs (associated most famously with Michael Frede). (shrink)
