In my paper, I dispute Christian Hengstermann’s analysis of More’s philosophical system as a form of panentheistic panpsychism in which matter is alive by virtue of being the last emanation from God. I show that, in his mature period, More explicitly rejected such an emanationist doctrine and attributed the non-mechanical powers of matter to an outside immaterial principle, the Spirit of Nature. Ultimately, this leads to a system in which divine space, the Spirit of Nature and the spirit of God (...) are representations of various aspects of the divine essence, as it is at work in the world. On the other hand, matter is not part of this triadic structure and can only be said to be alive at the cost of a rather counterintuitive redefinition of the notion of “life”. (shrink)

It is widely held that assertions are partially governed by an epistemic norm. But what is the epistemic condition set out in the norm? Is it knowledge, truth, belief, or something else? In this paper, I defend a view similar to that of Stanley (2008), according to which the relevant epistemic condition is epistemic certainty, where epistemic certainty (but not knowledge) is context-sensitive. I start by distinguishing epistemic certainty, subjective certainty, and knowledge. Then, I explain why it's much more plausible (...) to think that "certain", rather than "know", is context-sensitive. After that, I respond to an important worry raised by Pritchard, according to which the proposed view is too strong to accommodate our current practice of assertion. I then show that the main linguistic and conversational data advanced in the recent literature in favour of the knowledge condition are best explained by the certainty view. Finally, I offer two principled considerations: the certainty view is the only one compatible with three independently plausible claims and it fits very well with the common thought that knowledge does not entail certainty.

Is knowledge the epistemic norm of action and assertion? Gettier and justified-false-belief cases have been raised as counterexamples to the necessity direction of that claim. Most knowledge normers reply by distinguishing permissibility from excusability. An important objection to this move, however, is that it requires a still lacking view of epistemic excuses sufficiently general to cover all the cases, correctly relating the supposed excuse to the subject's cognitive life, and not collapsing into an account of the fundamental normative standard (see (...) Gerken 2017). In this paper, I rely on independent work in epistemology and cognitive science to suggest a novel account of epistemic excuses in terms of epistemic feelings. In contrast to other existing accounts, this account is immune from the above objection and can thus be used to rescue the knowledge norm. (shrink)

A certain number of cases suggest that our willingness to ascribe “knowledge” can be influenced by practical factors. For revisionary proposals, they indicate that the truth‐values of “knowledge” ascriptions vary with practical factors. For conservative proposals, on the contrary, nothing surprising is happening. Standard pragmatic approaches appeal to pragmatic implicatures and psychological approaches to the idea that belief formation is influenced by practical factors. Conservative proposals have not yet offered a fully satisfactory explanation, though. In this article, I introduce and (...) defend a third conservative proposal which I call “Refined Invariantism”. The two main claims of this proposal are that (1) we should distinguish between high stakes cases in which the subject does not believe (that he knows) the target proposition and those in which he believes (that he knows) the target proposition and that (2) we should adopt a psychological treatment for the first kind of case and a pragmatic treatment based on the epistemic standards for appropriate assertion and action for the second kind of case. I argue that this new combined approach avoids the main pitfalls of its two conservative rivals and that it gives new life to the generality objection levelled against revisionary views. (shrink)

Among the main reactions to scepticism, fallibilism is certainly the most popular nowadays. However, fallibilism faces a very strong and well-known objection. It has to grant that concessive knowledge attributions—assertions of the form “I know that p but it might be that not p”—can be true. Yet, these assertions plainly sound incoherent. Fallibilists have proposed to explain this incoherence pragmatically. The main proponents of this approach appeal to Gricean implicatures (Rysiew in Noûs 35(4):477514, 2001; Dougherty and Rysiew in Philos Phenomenol (...) Res 78(1):123132, 2009; Dougherty and Rysiew in Synthese 181(3):395403, 2011). Very recently, some philosophers have observed that fallibilists can also explain this apparent incoherence pragmatically if they embrace a (context-sensitive) certainty norm for assertion (Petersen in Synthese 196(11):4691–4710, 2019; Beddor in Philos Impr 20(8), 2020; Vollet in Dialectica 74:3, 2020). In this paper, I argue for the superiority of this latter explanation over its older rivals. (shrink)

According to a widely discussed view, knowledge plays a significant normative role in action: It is epistemically rational to treat p as your reason for action if and only if you know that p. As many philosophers have observed, however, this view clashes with the claim that knowledge is moderate and stable. For, granting that claim, there will be high stakes cases in which knowledge seems insufficient. To deal with such cases, some philosophers embracing the knowledge norm combine three independently (...) plausible claims. First, they say that no non-trivial condition is luminous; second, they say that doing something while not being in a position to know that that is appropriate is bad (in high stakes cases); third, they say that in the high stakes cases in question, the subject knows but fails to be in a position to know that she knows (Williamson Philos Q 55:213–235, 2005). This paper argues that this account can overcome the main objections already raised in the literature, but that it still faces the apparently insurmountable challenge of providing a natural and helpful way of substantiating the second claim. (shrink)

The traditional view in epistemology has it that knowledge is insensitive to the practical stakes. More recently, some philosophers have argued that knowledge is sufficient for rational action: if you know p, then p is a reason you have (epistemically speaking). Many epistemologists contend that these two claims stand in tension with one another. In support of this, they ask us to start with a low stakes case where, intuitively, a subject knows that p and appropriately acts on p. Then, (...) they ask us to consider a high stakes version of the case where, intuitively, this subject does not know that p and could not appropriately act on p without double-checking. Finally, they suggest that the best explanation for our shifty intuitions is that p is a reason the subject has in the low stakes case but not in the high stakes case. In short, according to this explanation, having a reason (in the epistemic sense) is sensitive to the stakes. If so, either knowledge is sensitive to the stakes or else you can know that p even if p is not a reason you have (in the epistemic sense). In this paper, I consider more closely the relation between having a reason (in the epistemic sense) and having a reason to check. I argue that the supposition that if one has p as a reason (in the epistemic sense) then one has a reason not to check whether p, or no reason to check whether p, is highly doubtful. On the contrary, I suggest, it is plausible that, given our fallibility, one always has an epistemic reason to check whether p, whether or not p is a reason one has (in the epistemic sense). On the basis of this observation, I show that one can offer a new way of explaining the cases in question, allowing us to reconcile the traditional view about knowledge and the sufficiency of knowledge for rational action.

Many philosophers agree that there is an epistemic norm governing action. However, they disagree on what this norm is. It has been observed that the word ‘know’ is prominent in ordinary epistemic evaluations of actions. Any opponent of the knowledge norm must provide an explanation of this fact. Gerken has recently proposed the most developed explanation. It invokes the hypothesis that, in normal contexts, knowledge-level warrant is frequently necessary and very frequently sufficient (Normal Coincidence), so that knowledge-based assessments would be (...) a good heuristic for practical reasoning and epistemic evaluations of action. In this paper, I raise three problems for this approach. First, I argue that Normal Coincidence is ad hoc: it relies on an unsupported frequency hypothesis that we should expect to be false given the warrant account that Gerken also endorses. Second, I argue that, in any case, Normal Coincidence is insufficient to support the hypothesis that knowledge-based evaluation of action constitutes a good heuristic. Third, I consider three other hypotheses close to Normal Coincidence apparently more likely to support the heuristic hypothesis, but I argue that they seem even more ad hoc than Normal Coincidence.

A certain number of philosophers are attracted to the idea that knowledge is the epistemic norm of practical reasoning in the sense that it is epistemically appropriate to rely on p in one’s practical reasoning if and only if one knows that p. A well-known objection to the sufficiency direction of that claim is that there are cases in which a subject supposedly knows that p and yet should not rely on p. In light of the distinction between sufficient and (...) insufficient reasons, some philosophers contend that these cases are inconclusive. In this paper, I argue that this insufficient reason manoeuvre is defective because it either misconstrues the relevant cases or is at odds with strong intuitions about how we (should) reason. I then put forward further considerations relative to the instability of some pieces of reasoning and show how they can be explained by a certainty norm for practical reasoning. (shrink)

Pascal Engel défend explicitement le purisme (ou l’intellectualisme). Selon la version générale de cette thèse, les facteurs qui déterminent si une croyance est justifiée, ou si elle est une connaissance, ne concernent que la vérité. Ils sont totalement indépendants des désirs ou des préférences du sujet, ainsi que des conséquences pratiques potentielles du fait de posséder ces croyances. Dans son article « Pragmatic Encroachment and Epistemic Value » (2009), P. Engel concède que des facteurs pratiques peuvent déterminer la quantité de (...) données (ou la justification) dont on a besoin pour savoir ou croire, tout en maintenant que cela n’affecte pas le purisme épistémique (dans sa version évidentialiste) sur les notions de donnée ou de degré de justification. Mais cela ne revient-il pas tout simplement à concéder l’impurisme épistémique au moins à propos de la connaissance ou de la justification simpliciter des croyances ? Dans cet article, j’examine en détails la position de P. Engel. Je montre que, correctement comprise, elle est intégralement puriste. En considérant le principe connaissance-action, je soulève néanmoins un dilemme pour son approche, jetant ainsi un doute sur le potentiel qu’elle aurait à fournir une réponse puriste satisfaisante à l’argument fondamental motivant l’impurisme épistémique.

Classically, an osculating circle at a point of a planar curve is introduced technically, often with formula giving its radius and the coordinates of its center. In this note, we propose a new and intuitive definition of this concept: among all the circles which have, on the considered point, the same tangent as the studied curve and thus seem equal to the curve through a microscope, the osculating circle is this that seems equal to the curve through a microscope within (...) microscope.

In the 21st century knowledge-centered approaches, which take knowledge as the starting-point for elucidation of other epistemic notions (e.g. belief, rationality), have come to the fore in analytic epistemology. This volume extends the knowledge-first program by exploring how these approaches fare in new fields inside and beyond epistemology.

Certainty The following article provides an overview of the philosophical debate surrounding certainty. It does so in light of distinctions that can be drawn between objective, psychological, and epistemic certainty. Certainty consists of a valuable cognitive standing, which is often seen as an ideal. It is indeed natural to evaluate lesser cognitive standings, in particular … Continue reading Certainty →.

During the last 20 years, knowledge-centered approaches have become increasingly popular in analytic epistemology. Rather than trying to account for knowledge in other terms, these approaches take knowledge as the starting point for the elucidation of other epistemic notions (such as belief, justification, rationality, etc.). Knowledge-centered approaches have been so influential that it now looks like epistemology is undergoing a factive turn. However, relatively little has been done to explore how knowledge-centered views fare in new fields inside and beyond epistemology (...) strictly understood. This volume aims at remedying this situation by putting together contributions that investigate the significance of knowledge in debates where its roles have been less explored. The goal is to see how far knowledge-centered views can go by exploring new prospects and identifying new trends of research for the knowledge-first program. Extending knowledge-centered approaches in this way not only promises to deliver novel insights in these neglected fields, but also to revisit more traditional debates from a fresh perspective. As a whole, the volume develops and evaluates the knowledge-first program in original and fertile ways. (shrink)

Positions is a collection of three interviews with Jacques Derrida that illuminate and make more accessible the complex concepts and terms treated extensively in such works as Writing and Difference and Dissemination. Derrida takes positions on his detractors, his supporters, and the two major preoccupations of French intellectual life, Marxism and psychoanalysis. The interviews included in this volume offer a multifaceted view of Derrida. "Implications: Interview with Henri Ronse" contains a succinct statement of principles. "Seminology and Grammatology: Interview (...) with Julia Kristeva" provides important clarifications of the role played by linguistics in Derrida's work. "Positions: Interview with Jean-Louis Houdebine and Guy Scarpetta" is a wide-ranging discussion that touches on many of the polemics that Derrida's work as provoked. Alan Bass, whose translation of Writing and Difference was highly praised for its clarity, accuracy, and readability, has provided extremely useful critical notes, full of vital information, including historical background.

We apply Benacerraf’s distinction between mathematical ontology and mathematical practice to examine contrasting interpretations of infinitesimal mathematics of the seventeenth and eighteenth century, in the work of Bos, Ferraro, Laugwitz, and others. We detect Weierstrass’s ghost behind some of the received historiography on Euler’s infinitesimal mathematics, as when Ferraro proposes to understand Euler in terms of a Weierstrassian notion of limit and Fraser declares classical analysis to be a “primary point of reference for understanding the eighteenth-century theories.” Meanwhile, scholars like (...) Bos and Laugwitz seek to explore Eulerian methodology, practice, and procedures in a way more faithful to Euler’s own. Euler’s use of infinite integers and the associated infinite products are analyzed in the context of his infinite product decomposition for the sine function. Euler’s principle of cancellation is compared to the Leibnizian transcendental law of homogeneity. The Leibnizian law of continuity similarly finds echoes in Euler. We argue that Ferraro’s assumption that Euler worked with a classical notion of quantity is symptomatic of a post-Weierstrassian placement of Euler in the Archimedean track for the development of analysis, as well as a blurring of the distinction between the dual tracks noted by Bos. Interpreting Euler in an Archimedean conceptual framework obscures important aspects of Euler’s work. Such a framework is profitably replaced by a syntactically more versatile modern infinitesimal framework that provides better proxies for his inferential moves. (shrink)

We give a general method for producing various effective Null and Positivstellensätze, and getting new Positivstellensätze in algebraically closed valued fields and ordered groups. These various effective Nullstellensätze produce algebraic identities certifying that some geometric conditions cannot be simultaneously satisfied. We produce also constructive versions of abstract classical results of algebra based on Zorn's lemma in several cases where such constructive version did not exist. For example, the fact that a real field can be totally ordered, or the fact that (...) a field can be embedded in an algebraically closed field. Our results are based on the concepts we develop of dynamical proofs and simultaneous collapse. (shrink)

La désinstitutionalisation est devenue un thème central dans le domaine du handicap pour permettre aux personnes concernées un vie autonome et indépendante. La signification de la désinstitutionalisation ne peut être intelligible que si on analyse son terme opposé à savoir l’institution. Qu’est-ce qu’une institution par-delà la diversité de ses formes et de ses interprétations? Elle pose trois grands problèmes: l’institution est-elle réductrice des individus? Les individus s’y soumettent-ils complètement? Qu’est-ce qui peut la réguler? Considérer à cette hauteur toute institution apparaît (...) comme ambivalente, répressive mais pleine de ressources, consentie par ses usagers qui peuvent néanmoins la contester, reposant sur une fonction mais aussi un imaginaire. Cette analyse amène à concevoir la désinstitutionalisation comme une dynamique constante au sein même de l’institution, qui ne peut jamais se réduire à la notion d’établissement. Institution, dont ne peut se passer la société et qui assure les supports nécessaires pour réaliser cette autonomie et cette indépendance. Il s’agit d’un double processus. Cet environnement institutionnel fait partie des facteurs environnementaux qui déterminent la condition handicapée. Et toute institution est elle-même intégrée à un environnement institutionnel plus large. Il n’y a pas de fonctionnement en dehors d’un environnement institutionnel. Le problème est dès lors de s’assurer que cet environnement œuvre en faveur de la liberté des individus. (shrink)

As a young boy, Jacques Henri Lartigue set about passionately recording his life in photographs, first documenting his domestic circle and later capturing the auto races, air shows, and fashionable watering holes of the Belle époque. His images have so bewitched modern viewers that even scholars have failed to see them clearly. In Jacques Henri Lartigue: The Invention of an Artist, Kevin Moore puts to rest the long-held myth of Lartigue as a naïve boy genius whose (...) creations were based on instinct alone. Moore begins by exploring the milieu in which Lartigue became a photographer, examining his father's crucial role in teaching him the latest techniques as well as the larger context of the turn-of-the-century craze for amateur photography. Two events brought Lartigue before the public eye in America and created the Lartigue myth: In the summer of 1963, the first exhibition of Lartigue's work in the United States was held at the Museum of Modern Art, which hailed him as an important modernist photographer, a forerunner of the art-documentary style of the 1960s. That fall, Life magazine published a feature presenting his work as an optimistic and sentimental prologue to World War I. Both treatments portrayed him as a naïve genius and Lartigue happily participated in shaping this new persona. In Jacques Henri Lartigue: The Invention of an Artist, Moore successfully challenges the Lartigue myth using examples from popular magazines and the cinema. Illustrated with more than fifty of Lartigue's photographs and drawings as well as press imagery from the period, the book offers a radical reassessment of the photographer and his work. (shrink)
