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.

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...

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.

Aristotle's De Anima discusses the psychological causes of what he calls locomotion – i.e, roughly, purpose-driven behavior. One cause is desire. The other is cognition, which falls into two kinds: thought (nous) and imagination (phantasia). Aristotle’s discussion is dense and confusing, but I argue that we can extract from it an account that is coherent, compelling, and that in many ways closely anticipates modern psychological theories, in particular Dual Processing theory. Animals and humans are driven to pursue objects that attract (...) us. Objects take on that power when we cognize them as valuable. If we rely on imagistic, automatic, uncontrolled processing mechanisms – Aristotle’s phantasia, which closely anticipates the modern notion of Type 1 processing – our resulting desires and actions will be impulsive. If we rely instead on rational, critical, deliberative capacities – Aristotle’s thought, which closely anticipates the modern notion of Type 2 processing – our resulting desires and actions will be reflective. Animals are capable only of the first kind of behavior; the human psyche is constituted of an animal psyche united with an intellectual one, so we are capable of both. (shrink)

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)

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.

Frequent public uproar over forms of data science that rely on information about people demonstrates the challenges of defining and demonstrating trustworthy digital data research practices. This paper reviews problems of trustworthiness in what we term pervasive data research: scholarship that relies on the rich information generated about people through digital interaction. We highlight the entwined problems of participant unawareness of such research and the relationship of pervasive data research to corporate datafication and surveillance. We suggest a way forward by (...) drawing from the history of a different methodological approach in which researchers have struggled with trustworthy practice: ethnography. To grapple with the colonial legacy of their methods, ethnographers have developed analytic lenses and researcher practices that foreground relations of awareness and power. These lenses are inspiring but also challenging for pervasive data research, given the flattening of contexts inherent in digital data collection. We propose ways that pervasive data researchers can incorporate reflection on awareness and power within their research to support the development of trustworthy data science. (shrink)

If there is any consensus about knowledge in contemporary epistemology, it is that there is one primary kind: knowledge-that. I put forth a view, one I find in the works of Aristotle, on which knowledge-of – construed in a fairly demanding sense, as being well-acquainted with things – is the primary, fundamental kind of knowledge. As to knowledge-that, it is not distinct from knowledge-of, let alone more fundamental, but instead a species of it. To know that such-and-such, just like to (...) know a person or place, is to be well-acquainted with a portion of reality – in this case a fact. In part by comparing classic Gettier cases to cases in which one has true impressions of but fails to know a person, I argue that this account not only respects our intuitions about knowledge-that – in particular that it is or entails non-accidentally true justified belief – but also explains them, providing a compelling analysis.

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)

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)

L’article porte sur le rapport entre la phronèsis (prudence ou sagesse pratique) et la vertu éthique dans la conception aristotélicienne de l’action et du bonheur. La question principale est la suivante : faut-il penser, selon une conception « humienne », que, chez Aristote, les buts sont fixés par notre désir, tandis que la raison servirait de simple instrument pour déterminer les moyens de les atteindre? La thèse défendue est que la vertu de caractère donne bien le contenu des fins, mais (...) cela ne conduit pas à reléguer la phronèsis au rang de simple instrument. En effet, la phronèsis est l’excellence de la délibération sur les choses en vue d’une fin. Elle nous permet de comprendre ce que signifie avoir une fin. Pour le démontrer, l’auteur examine conjointement le fonctionnement des syllogismes délibératif et démonstratif, qui sont tous deux des arguments explicatifs. Cette comparaison permet à l’auteur d’établir que la vertu éthique donne le « que » (« quoi faire »), alors que la phronèsis permet de comprendre le « pourquoi », c’est-à-dire en vue de quelle fin l’action doit être accomplie. La vertu complète suppose de saisir le « pourquoi » ; c’est pourquoi la phronèsis a une importance éthique et est nécessaire au bonheur. (shrink)

The Physician Orders for Life-Sustaining Treatment Paradigm is designed to improve end-of-life care by converting patients' treatment preferences into medical orders that are transferable throughout the health care system. It was initially developed in Oregon, but is now implemented in multiple states with many others considering its use. An observational study was conducted in order to identify potential legal barriers to the implementation of a POLST Paradigm. Information was obtained from experts at state emergency medical services and long-term care organizations/agencies (...) in combination with a review of relevant state law. (shrink)

The most potentially problematic barriers are detailed statutory specifications for out-of-hospital DNR protocols. Other potential barriers include limitations on the authority to consent to forgo life-sustaining treatments, medical preconditions, and witnessing requirements for out-of-hospital DNR protocols.

Many tasks in statistical and causal inference can be construed as problems of entailment in a suitable formal language. We ask whether those problems are more difficult, from a computational perspective, for causal probabilistic languages than for pure probabilistic (or “associational”) languages. Despite several senses in which causal reasoning is indeed more complex—both expressively and inferentially—we show that causal entailment (or satisfiability) problems can be systematically and robustly reduced to purely probabilistic problems. Thus there is no jump in computational complexity. (...) Along the way we answer several open problems concerning the complexity of well-known probability logics, in particular demonstrating the ${\exists \mathbb {R}}$ -completeness of a polynomial probability calculus, as well as a seemingly much simpler system, the logic of comparative conditional probability.

Is there a need for a distinctively diachronic conception of metaphysical emergence? Here I argue to the contrary. In the main, my strategy consists in considering a representative sample of accounts of purportedly diachronic metaphysical emergence, and arguing that in each case, the purportedly diachronic emergence at issue either can (and should) be subsumed under a broadly synchronic account of metaphysical emergence, or else is better seen as simply a case of causation. In addition, I consider and argue against the (...) suggestion that 'in-principle unpredictability' accounts of diachronic emergence support there being distinctively diachronic metaphysical emergence.

Fallibilists claim that one can know a proposition on the basis of evidence that supports it even if the evidence doesn't guarantee its truth. Jessica Brown offers a compelling defence of this view against infallibilists, who claim that it is contradictory to claim to know and yet to admit the possibility of error.

A core principle of modern science holds that a scientific explanation must not attribute will or agency to natural phenomena.The Restless Clock examines the origins and history of this, in particular as it applies to the science of living things. This is also the story of a tradition of radicals—dissenters who embraced the opposite view, that agency is an essential and ineradicable part of nature. Beginning with the church and courtly automata of early modern Europe, Jessica Riskin guides us (...) through our thinking about the extent to which animals might be understood as mere machines. We encounter fantastic robots and cyborgs as well as a cast of scientific and philosophical luminaries, including Descartes and Leibnitz, Lamarck and Darwin, whose ideas gain new relevance in Riskin's hands. The book ends with a riveting discussion of how the dialectic continues in genetics, epigenetics, and evolutionary biology, where work continues to naturalize different forms of agency.The Restless Clock reveals the deeply buried roots of current debates in artificial intelligence, cognitive science, and evolutionary biology.

Traditional procedures for rational updating fail when it comes to self-locating opinions, such as your credences about where you are and what time it is. This paper develops an updating procedure for rational agents with self-locating beliefs. In short, I argue that rational updating can be factored into two steps. The first step uses information you recall from your previous self to form a hypothetical credence distribution, and the second step changes this hypothetical distribution to reflect information you have genuinely (...) learned as time has passed. While the second step resembles traditional procedures of updating by conditionalization, the first is best understood by analogy to traditional models of how agents transmit self-locating opinions through ordinary interpersonal communication.

Has the renewal of interest in the ostensible agency of living beings signaled an advance from a merely heuristic Kantian sense of purposiveness to an unequivocally, empirically grounded research program or are there as yet hidden tensions or contradictions in, for example, the organizational autonomy approach to natural agency? Can normativity be found to be immanent in nature but only beginning with the living cell or must a thoroughgoing naturalism find the seeds of normativity immanent throughout abiotic as well as (...) biotic nature? Beginning with a brief exposition of Kant´s influential treatment and recommendation for how to methodologically combine what he took to be the inevitable epistemological limit to explaining the origins of ostensible biotic purposefulness with the legitimate intentions of scientific research and explanation, this essay will critically engage with three recent essays that attempt to grapple with the preceding questions. Having putatively raised questions about the consistency and adequacy of each of the individual positions, the essay will attempt to move synthetically, drawing upon aspects of all three contributions, in the direction of a “cooperativity theoretic” approach to incipient natural normativity and agency.

I argue that the best explanation of the multiplicity of available frameworks for treating any given philosophical topic is that philosophy currently (though not insuperably) lacks fixed standards; I then go on to identify three barriers to philosophical progress associated with our present epistemic situation. First is that the lack of fixed standards encourages what I call “intra‐disciplinary siloing,” and associated dialectical and argumentative failings; second is that the lack of fixed standards makes room for sociological factors (including elite influence (...) and disciplinary inertia) to be determinative of which philosophical frameworks are embraced; third is that the lack of fixed standards encourages (implicit and/or explicit) bias. I close by offering some suggestions about how to move beyond these barriers, even in the absence of fixed standards. (shrink)
