In this paper I argue for a doctrine I call ?infallibilism?, which I stipulate to mean that If S knows that p, then the epistemic probability of p for S is 1. Some fallibilists will claim that this doctrine should be rejected because it leads to scepticism. Though it's not obvious that infallibilism does lead to scepticism, I argue that we should be willing to accept it even if it does. Infallibilism should be preferred because it has greater explanatory power than fallibilism. In particular, I argue that an infallibilist can easily explain why assertions of ?p, but possibly not-p? (where the ?possibly? is read as referring to epistemic possibility) is infelicitous in terms of the knowledge rule of assertion. But a fallibilist cannot. Furthermore, an infallibilist can explain the infelicity of utterances of ?p, but I don't know that p? and ?p might be true, but I'm not willing to say that for all I know, p is true?, and why when a speaker thinks p is epistemically possible for her, she will agree (if asked) that for all she knows, p is true. The simplest explanation of these facts entails infallibilism. Fallibilists have tried and failed to explain the infelicity of ?p, but I don't know that p?, but have not even attempted to explain the last two facts. I close by considering two facts that seem to pose a problem for infallibilism, and argue that they don't

The conventioral understanding takes God to pray a pivotal philosophical role in Descartes's epistemological project. Michael Della Rocca disagrees with this interpretation. In a recent article, " Descartes, the Cartesian Circle, and epistemology without God," he forcefully argues for the view that takes God to be peripheral and at the fringe of Descartes's account of knowledge. He argues that Descartes renders God less important in his epistemology simply in virtue of having normative certainty of clear and distinct ideas or perceptions prior to his theological argument. This paper generally argues that although it could be said that Descartes has normative certainty of some claims before his arguments for God's existence, it is misleading to claim that God plays no pivotal philosophical role in Descartes's epistemological project. In particular, it argues that since the relevant conditions for scientia for Descartes include normative certainty of clear and distinct perceptions and understanding of the metaphysical foundations of cognition it is mistaken to suppose that God takes on a less than central role in Descartes's epistemology.

Many contemporary social epistemologists take themselves to be combatting an individualist approach to knowledge typified by Descartes. Although I agree that Descartes presents an individualist picture of scientific knowledge, he does allow some practical roles for reliance on the testimony and beliefs of others. More importantly, however, his reasons for committing to individualism raise important issues for social epistemology, particularly about how reliance on mere testimony can propagate prejudices and inhibit genuine understanding. The implications of his views are worked out more fully by some of his immediate successors; I examine how François Poulain de la Barre, and (briefly) Mary Astell analyze the social conditions for epistemic agency in a Cartesian vein.

In his article 'Individualism and Descartes' (Teorema, vol. 16, pp. 71-86), William Ferraiolo puts into question the widely accepted interpretation of Descartes as an individualist about mental content. In this paper, I defend this interpretation of Descartes thought against Ferraiolo's objections. I hold, first, that the interpretation is not historically misguided. Second, I try to show that Descartes’s endorsement of anti-individualism would lead either to depriving skeptical hypotheses of their force or to rejecting the epistemological privilege of the first person. Finally, I argue that Ferraiolo’s objections to the individualistic interpretation rest on two important errors: a misapprehension of the argumentative order of the Meditations and a confusion between the notions of causal and constitutive dependence of content on the external environment.

The theorist who denies the objective reality of non-relational temporal properties, or ‘A-series’ determinations, must explain our experience of the passage of time. D.H. Mellor, a prominent denier of the objective reality of temporal passage, draws, in part, on Kant in offering a theory according to which the experience of temporal passage is the result of the projection of change in belief. But Mellor has missed some important points Kant has to make about time-awareness. It turns out that Kant's theory of time-awareness also involves projection – but for him, the projection of temporal passage is necessary to any coherent experience at all, and for this reason events in the world cannot be represented except as exhibiting real tensed change. Consequently we cannot intelligibly suppose the world we know to be without the passage of time. This fact would permit a modest transcendental argument the conclusion of which is that we are entitled to describe the world in terms of temporal passage.

Kant’s three Analogies of Experience, in his Critique of Pure Reason, represent a highly condensed attempt to establish the metaphysical foundations of Newtonian physics. His strategy is to show that the organization of experience in terms of a world of enduring substances undergoing mutual causal interaction is a necessary condition of the temporal ordering even of one’s own subjective states, and thus of coherent experience itself. In his Third Analogy—an examination of the necessary conditions of judgments of simultaneous existence—he argues that certain conceptual presuppositions consistent with Newtonian physics are necessary to time-awareness. His argument, however, appears to be undermined by conventionalism in natural science generally, and by the conventionality of simultaneity in particular. In this paper I discuss Kant’s claims in light of contemporary relativity theory. I suggest that, while his project is obsolete in major respects, there may still be useful insights into time-awareness to be drawn from his work.

This is the introduction chapter of A Companion to the Philosophy of Time, which tackles the historical development of the philosophy of time. This volume brings together experts in the various branches of the philosophy of time from around the world. Part I of this volume features essays on the philosophy of time from the pre‐Socratic period through the twentieth century. Parts II and III reflect, respectively, on the physics and metaphysics of time, and on the study of the experience of time. Together, Parts II and III address the fundamental question of contemporary time studies: distinguishing between time as it is in itself, and time as humans perceive and experience it; between the scientific and manifest images of time.

This edited collection presents the latest cutting-edge research in the philosophy and cognitive science of temporal illusions. Illusion and error have long been important points of entry for both philosophical and psychological approaches to understanding the mind. Temporal illusions, specifically, concern a fundamental feature of lived experience, temporality, and its relation to a fundamental feature of the world, time, thus providing invaluable insight into investigations of the mind and its relationship with the world. The existence of temporal illusions crucially challenges the naïve assumption that we can simply infer the temporal nature of the world from experience. This anthology gathers eighteen original papers from current leading researchers in this subject, covering four broad and interdisciplinary topics: illusions of temporal passage, illusions and duration, illusions of temporal order and simultaneity, and the relationship between temporal illusions and the cognitive representation of time.

An anti-skeptical transcendental argument can be loosely defined as an argument that purports to show that some experience or knowledge of an external world is a necessary condition of our possession of some knowledge, concept, or cognitive ability that we know we have. In this dissertation I examine transcendental arguments by focusing on one such argument given by Immanuel Kant in his Critique of Pure Reason, along with some attempts to interpret that argument by contemporary commentators. ;I proceed by dividing anti-skeptical transcendental arguments into three types: epistemological, verificationist, and psychological. I examine arguments of the first two types and show why they cannot succeed against the skeptic. I then argue that Kant's Refutation of Idealism is of a different type: it is psychological in that it concerns the necessary conditions of our forming beliefs of certain kinds. Many contemporary Kant scholars have claimed that his anti-skeptical strategy relies on phenomenalism or verificationism; I argue, however, that Kant in the Refutation employs a clever and hitherto unappreciated strategy which involves an empiricist principle concerning the origin of simple ideas, and which does not require either phenomenalism or verificationism. I conclude with an analysis and assessment of Kant's argument

Ernest Sosa's virtue perspectivism can be thought of as an attempt to capture as much as possible of the Cartesian project in epistemology while remaining within the framework of externalist fallibilism. I argue (a) that Descartes's project was motivated by a desire for intellectual stability and (b) that his project does not suffer from epistemic circularity. By contrast, Sosa's epistemology does entail epistemic circularity and, for this reason, proves unable to secure the sort of intellectual stability Descartes wanted. I then argue that this leaves Sosa's epistemology vulnerable to an important kind of skepticism

This paper considers just how memory works throughout the Meditations to adduce Descartes’s conception of memory. Examining the meditator’s memory at work raises some questions about the nature of Cartesian memory and its epistemic role. What is the distinction between remembering and repeating a thought? If remembering is not simply repeating a thought, then what is involved in properly remembering? Can we remember properly while adding or shifting content, say, in virtue of articulating relations between ideas? If so, what is the relation between remembering and reasoning, since both would then involve relations of ideas? These questions become salient in considering the meditator’s creative recollections in the Third and especially the Sixth Meditations. After briefly considering what Descartes does say about memory, I consider two other strategies for addressing those questions: an analogy with innate ideas, and attending to the role that other thinkers play in one’s own recollections.

Descartes held the following view of declarative memory: to remember is to reconstruct an idea that you intellectually recognize as a reconstruction. Descartes countenanced two overarching varieties of declarative memory. To have an intellectual memory is to intellectually reconstruct a universal idea that you recognize as a reconstruction, and to have a sensory memory is to neurophysiologically reconstruct a particular idea that you recognize as a reconstruction. Sensory remembering is thus a capacity of neither ghosts nor machines, but only of human beings qua mind-body unions. This interpretation unifies Descartes’s various remarks (and conspicuous silences) about remembering, from the 1628 Rules for the Direction of the Mind through the suppressed-in-1633 Treatise of Man to the 1649 Passions of the Soul. It also rebuts a prevailing thesis in the current secondary literature—that Cartesian critters can remember—while incorporating the textual evidence for that thesis—Descartes’s detailed descriptions of the corporeal mechanisms that construct sensory memories.

“But surely if it's not irrational, it can’t be OCD!” my friend exclaimed, when I told them about the paper Carolina Flores and Brent Kious provided their excellent comments for. In all fairness, my friend is not working in philosophy, or psychiatry, or in psychology. Still, I take their sentiment to be expressive of a widely held view: if you have a certain mental illness, then you must be irrational. Conversely, rationality guarantees mental health; the sane life is the rational life. In my paper, I attempted to complicate this picture. My main line of thought was that if the sane life is the rational life, we do not have a good conception of rationality yet. For, our best theories of rationality fail to capture what is going wrong in some cases of obsessive-compulsive disorder (OCD). Addressing the criticisms raised by my commentators will allow me to clear up some misunderstandings and sketch avenues for further work.

What makes up reality, and how? What kinds of entity are fundamental to reality, and how do dependent entities depend on the fundamental ones? How does one entity metaphysically ground another? These questions are central to contemporary metaphysics. The papers in this collection, written by a new generation of metaphysicians, address these and related questions. They investigate the metaphysical concepts of grounding and fundamentality, and the relationship between the fundamental and all the other parts of reality. Together, these papers represent the cutting-edge of a central topic in contemporary metaphysics

Information is often modelled as a set of relevant possibilities, treated as logically possible worlds. However, this has the unintuitive consequence that the logical consequences of an agent's information cannot be informative for that agent. There are many scenarios in which such consequences are clearly informative for the agent in question. Attempts to weaken the logic underlying each possible world are misguided. Instead, I provide a genuinely psychological notion of epistemic possibility and show how it can be captured in a formal model, which I call a fan. I then show how to use fans to build formal models of being informed, as well as knowledge, belief and information update.
