A very influential idea in the epistemology of modality is that we acquire knowledge of metaphysical modality through knowledge of essence. As a consequence, the epistemology of essence becomes crucial in the attempt to answer the question of how we come to know modal propositions. In this paper I investigate Lowe’s and Hale’s approach to the epistemology of essence and argue that both of them remain in a crucial, structural sense incomplete. Systematizing this criticism against Lowe and Hale, I then (...) break down desiderata of what I call a structurally complete picture of the epistemology of essence. Finally, I discuss Husserl’s epistemology of essence and defend it against a notorious objection. However, Husserl’s approach also seems to remain incomplete, due to its appeal to imagination, which operates on the basis of background assumptions that are themselves in need of justification. I indicate, however, that a Husserlian theory of intuitive awareness of universals might supply us with (direct) justification of these background assumptions and, hence, that we might be able to paint a structurally complete picture of the epistemology of essence with Husserlian means.

There is currently intense interest in the question of the source of our presumed knowledge of truths concerning what is, or is not, metaphysically possible or necessary. Some philosophers locate this source in our capacities to conceive or imagine various actual or non-actual states of affairs, but this approach is open to certain familiar and seemingly powerful objections. A different and ostensibly more promising approach has been developed by Timothy Williamson, according to which our capacity for modal knowledge is just (...) an extension, or by-product, of our general capacity to acquire knowledge of true counterfactual conditionals — a capacity that we deploy ubiquitously in everyday life. Williamson’s account crucially involves a thesis to the effect that modal truths can be explained in terms of counterfactual truths. In this paper, I query Williamson’s account on a number of points, including this thesis. My positive proposal, which owes a debt to the work of Kit Fine on modality and essence, appeals instead to our capacity to grasp essences, understood in a neo-Aristotelian fashion, according to which essences are expressed by ‘real definitions’.

Essays on Existence and Essence presents a series of writings--including several previously unpublished--by Bob Hale on the topics of ontology and modality. The essays develop and consolidate a number of themes central to his work and to contemporary metaphysics, logic, and philosophy of language. They display Hale's innovative approach to some of the most fundamental issues in philosophy, in dialogue with other leading philosophers. The notion of a definition is examined as it applies both to words--verbal definitions-and to things--real definitions--and (...) the relations between these are brought out in order to address problems in the metaphysics of necessity and the semantics and epistemology of modality. Hale argues for an essentialist theory of the source of necessity and our knowledge of it, and provides rigorous and inventive responses to problems such a theory might face. This theoretical framework is applied to the recently influential truthmaking approach to semantics and logic, developing an exact truthmaker account of universal quantification and modal statements. Other topics covered include the Fregean theory of ontological categories, the status of second-order logic, the metaphysics of numbers, and the nature of analytic propositions. The volume opens with a substantial introduction by Kit Fine, providing a critical examination of Hale's philosophy, and closes with a complete bibliography of Hale's writings. (shrink)

In this paper, it is argued that metaphysics, conceived as an inquiry into the ultimate nature of mind-independent reality, is a rationally indispensable intellectual discipline, with the a priori science of formal ontology at its heart. It is maintained that formal ontology, properly understood, is not a mere exercise in conceptual analysis, because its primary objective is a normative one, being nothing less than the attempt to grasp adequately the essences of things, both actual and possible, with a view to (...) understanding as far as we can the fundamental structure of reality as a whole. Accordingly, it is urged, the deliverances of formal ontology have a modal and epistemic status akin to those of other a priori sciences, such as mathematics and logic, rather than constituting rivals to the claims of the empirical sciences, such as physics.

The fourteen papers in this collection offer a variety of original contributions to the epistemology of modality. In seeking to explain how we might account for our knowledge of possibility and necessity, they raise some novel questions, develop some unfamiliar theoretical perspectives, and make some intriguing proposals. Collectively, they advance our understanding of the field. In Part I of this Introduction, I give some general background about the contemporary literature in the area, by sketching a timeline of the main tendencies (...) of the past twenty-five years or so, up to the present debates. Next, I focus on four features that largely characterize the latest literature, and the papers in the present collection in particular: (i) an endorsement of the importance of essentialism; (ii) a shift to a “metaphysics-first” approach to modal epistemology; (iii) a focus on metaphysical modality as opposed to other kinds of modality; and (iv) a preference for non-uniform modal epistemology. In Part II, I present the individual papers in the volume. These are organized around the following four chapters, based on their topic: (A) Skepticism & Deflationism; (B) Essentialism; (C) Non-Essentialist Accounts; (D) Applications. -/- LIST OF CONTRIBUTORS: Francesco Berto; Stephen Biggs & Jessica Wilson; Justin Clark-Doane; Philip Goff; Bob Hale; Frank Jackson; Mark Jago; Boris Kment; Antonella Mallozzi; Graham Priest; Gabriel Rabin; Amie Thomasson; Anand Vaidya & Michael Wallner; Jennifer Wang. -/- The volume is dedicated to the memory of Bob Hale. -/- .

The chapter discusses the issue of how we may achieve knowledge of essence. It offers a critical survey of the main theories of knowledge of essence that have been proposed within contemporary debates, particularly by Lowe, Hale, Oderberg, Elder, and Kment.

Kit Fine famously objected against the idea that essence can be successfully analyzed in terms of de re necessity. In response, I want to explore a novel, interesting, but controversial modal account of essence in terms of intrinsicality and grounding. In the first section, I will single out two theoretical requirements that any essentialist theory should meet—the essentialist desideratum and the essentialist challenge—in order to clarify Fine’s objections. In the second section, I will assess Denby’s improved modal account, which appeals (...) to the notion of intrinsicality, and argue that it is untenable. In the third section, I will explain how, when combined with a modal-existential criterion, a hyperintensional account of intrinsicality—in the same vein as Bader (J Philos 110(10): 525–563, 2013) and Rosen (in: Hale and Hoffman (eds) Modality: Metaphysics, logic, and epistemology, Oxford, OUP, 2010)—can help successfully address Fine’s counterexamples. In the fourth section, I will evaluate how this novel analysis of essence stands with respect to sortal, origin, and natural kinds essentialism and discuss potential objections and difficulties.

This article begins by presenting the two most important transformations that establish a genuine Husserlian approach to the imagination: the first lies in the grasping of imagination, despite its essential differences with perception and hallucination, as an intuitive, or sensuous consciousness ; the second lies in the insight that imagination, or better – phantasy –, requires no images, mental or otherwise. Further, the distinction between pure and perceptual phantasies and their respective fictional objects is drawn out. A comparison between pure (...) phantasy and memory, then leads to a closer look at the role of inner consciousness in pure phantasy and to a clarification of the ‘splitting of the subject’. The exploration of this split allows us to trace the role of the real-ego and the phantasy-ego in pure phantasy, which opens the exploration of phantasy as a consciousness of possibilities. This helps us gain clarity about the nature of both real and ideal possibilities and the respective modes of phantasy. Objects of phantasy also most easily lend themselves to an eidetic variation and to an insight into essences. Phenomenological essences concern the ideal possibility of real and ideal objects and of their experience. It is through their contribution to insight into the real and ideal conditions of possibility of different forms of intentional acts that acts of phantasy best show their potential for Husserl’s project of philosophy as a rigorous science. Imagination or fiction becomes, in his own words, the ‘vital element of phenomenology.’. (shrink)

This book is a collection of essays written by Bob Hale (three co-authored), with a critical introduction from Kit Fine. They comprise Hale’s final years of work, adding to and extending beyond his landmark monograph Necessary Beings: An Essay on Ontology, Modality, and the Relations Between Them (OUP, 2013, 2nd edition 2015). The essays develop and consolidate several key themes in Hale’s work, most notably the notion of definition, especially as it extends beyond definition of a word to definition of (...) a thing more generally, and its relations to essence and existence; how the recently influential notion of truthmaking relates to and illuminates some of these issues; and ontological questions connected with Hale’s metaphysical commitments on the one hand, and his commitments in the foundations of mathematics on the other. Several of the essays engage with and respond to work by Kit Fine, and contributions to Being Necessary: Themes of Ontology and Modality from the Work of Bob Hale (OUP 2018). As such, these essays also demonstrate a rich and fruitful philosophical dialogue between Hale and his critics and friends. (shrink)

The philosophy of modality investigates necessity and possibility, and related notions--are they objective features of mind-independent reality? If so, are they irreducible, or can modal facts be explained in other terms? This volume presents new work on modality by established leaders in the field and by up-and-coming philosophers. Between them, the papers address fundamental questions concerning realism and anti-realism about modality, the nature and basis of facts about what is possible and what is necessary, the nature of modal knowledge, modal (...) logic and its relations to necessary existence and to counterfactual reasoning. The general introduction locates the individual contributions in the wider context of the contemporary discussion of the metaphysics and epistemology of modality. (shrink)

Bob Hale presents a broadly Fregean approach to metaphysics, according to which ontology and modality are mutually dependent upon one another. He argues that facts about what kinds of things exist depend on facts about what is possible. Modal facts are fundamental, and have their basis in the essences of things--not in meanings or concepts.

We may define words or concepts, and we may also, as Aristotle and others have thought, define the things for which words stand and of which concepts are concepts. Definitions of words or concepts may be explicit or implicit, and may seek to report preexisting synonymies, as Quine put it, but they may instead be wholly or partly stipulative. Definition by abstraction, of which Hume’s principle is a much discussed example, seek to define a term-forming operator, such as the number (...) operator, by fixing the truth-conditions of identity-statements featuring terms formed by means of that operator. Such definitions are a species of implicit definition. They are typically at least partly stipulative. Definitions of things, or real definitions, are, by contrast, typically conceived as true or false statements about the nature or essence of their definienda, and so not stipulative. There thus appears to be an obvious and head-on clash between taking Hume’s principle as an implicit and at least partly stipultative definition of the number operator and taking it as a real definition, stating the nature or essence of cardinal numbers. This paper argues that this apparent tension can be resolved, and that resolving it sheds light on part of the epistemology or essence and necessity, showing how some of our knowledge of essence and necessity can be a priori.

The present paper offers an analogical support for the use of rational intuition, namely, if we regard sense perception as a mental faculty that (in general) delivers justified beliefs, then we should treat intuition in the same manner. I will argue that both the cognitive marks of intuition and the role it traditionally plays in epistemology are strongly analogous to that of perception, and barring specific arguments to the contrary, we should treat rational intuition as a source of prima facie (...) justified beliefs. There are two main arguments against the intuition-perception analogy that I will consider and find lacking. First is that while we do use perceptions as evidence to believe certain propositions, in fact no one ever does use intuition evidentially. The second argument, stemming from experimental philosophy, grants that philosophers do use intuitions evidentially, but this practice is fatally unlike that of perception, in that perception yields warranted beliefs and intuition does not.

A priori reflection, common sense and intuition have proved unreliable sources of information about the world outside of us. So the justification for a theory of the categories must derive from the empirical support of the scientific theories whose descriptions it unifies and clarifies. We don’t have reliable information about the de re modal profiles of external things either because the overwhelming proportion of our knowledge of the external world is theoretical—knowledge by description rather than knowledge by acquaintance. This undermines (...) the traditional idea that to be an object of category C is to be an object with such- and-such characteristic possibilities of combination. But this is no loss because de re modal thought lacks utility for creatures like us. (shrink)

This introductory chapter gives a general survey of the research context, along with brief descriptions of the chapters collected here, indicating how they contribute to the three-year project which provided that context. Focusing on absolute notions of necessity and possibility, the project's principal aims were to explore the most fundamental questions and issues centred on them — ranging from scepticism about modal notions themselves, anti-realist view such as non-cognitivism, and the tenability of any sort of realism about modal facts, through (...) to questions about the metaphysics, logic, and epistemology of modality which any broadly realist view must answer.

One currently popular methodology of metaphysics has it that ‘intuitions’ play an evidential role with respect to metaphysical claims. This chapter defends a realist methodology of metaphysics that implies that any rational being, simply in virtue of being rational, is necessarily capable of grasping the essences of at least some mind-independent entities. The notion of essence in play here is Aristotelian, whereby an entity’s essence is captured by an account of what that entity is, or what it is to be (...) that entity. Concepts are just ways of thinking of things and, as such, may or may not be adequate to the real natures — the essences — of the things being thought of. Our ‘intuitions’, particularly as revealed by aptly constructed thought experiments, may cast interesting light on some of our concepts, but they are not and cannot be reliable guides to mind-independent truths of essence.

The present paper poses a new problem for moral luck. Defenders of moral luck uncritically rely on a broader theory of luck known as the control theory or the lack of control theory. However, there are are two other analyses of luck in the literature that dominate discussion in epistemology, namely the probability and modal theories. However, moral luck is nonexistent under the probability and modal accounts, but the control theory cannot explain epistemic luck. While some have posited that “luck” (...) is ambiguous, so that one theory of luck is operative with epistemic luck and a different theory works for moral luck, there are both semantic and philosophical reasons to reject luck ambiguity. Defenders of moral luck must engage with the broader literature on luck and either provide a comprehensive defense of the control theory or concede that moral luck is not a genuine thing in its own right.

Dummett's formulation presupposes a realistic attitude towards modality. And as also remarked, realism in this sense has not gone unchallenged. This chapter discusses a different form the realism it opposes may assume which entails, but goes appreciably beyond, the comparatively modest variety just sketched, and which has been the focus of much recent discussion: realism about possible worlds. It begins by drawing some distinctions among different notions of necessity and possibility. Probably the single most important distinction to be drawn is (...) between absolute and relative kinds or senses. In an early defense of realism, David Lewis gives some prominence to an argument which represents the central thesis of his realism. Lewis is chary of saying outright whether worlds themselves are concrete entities, pending clarification of the abstract/concrete distinction. Lewis's own discussion of the charge that his position is epistemologically bankrupt largely in presupposing that it will be based upon a causal constraint on knowledge. (shrink)

If metaphysics is centrally concerned with charting the domain of the possible, the only coherent account of the ground of metaphysical possibility and of our capacity for modal knowledge is to be found in a version of essentialism: a version that I call serious essentialism, to distinguish it from certain other views which may superficially appear very similar to it but which, in fact, differ from it fundamentally in certain crucial respects. This version of essentialism eschews any appeal whatever to (...) the notion of possible worlds in its account of the nature and ground of metaphysical possibility, for reasons that which I shall endeavour to explain and justify in this paper. (shrink)

Ontological dependence is a relation—or, more accurately, a family of relations—between entities or beings. For there are various ways in which one being may be said to depend upon one or more other beings, in a sense of “depend” that is distinctly metaphysical in character and that may be contrasted, thus, with various causal senses of this word. More specifically, a being may be said to depend, in such a sense, upon one or more other beings for its existence or (...) for its identity. Some varieties of ontological dependence may be analyzed in modal terms—that is, in terms of distinctly metaphysical notions of possibility and necessity—while others seem to demand an analysis in terms of the notion of essence. The latter varieties of ontological dependence may accordingly be called species of essential dependence. Notions of ontological dependence are frequently called upon by metaphysicians in their proposed analyses of other metaphysically important notions, such as the notion of substance. (shrink)

The article argues that modal concepts should be explained in terms of the essences or nature of things: necessarily p if, and because, there is something the nature of which ensures that p; possibly p if, and because, there is nothing whose nature rules out its being true that p. The theory is defended against various objections and difficulties, including ones arising from attributing essences to contingent individuals.

Forms of thought are involved whenever we name, describe, or identify things, and whenever we distinguish between what is, might be, or must be the case. It appears to be a distinctive feature of human thought that we can have modal thoughts, about what might be possible or necessary, and conditional thoughts, about what would or might be the case if something else were the case. Even the simplest thoughts are structured like sentences, containing referential and predicative elements, and studying (...) these structures is the main task of philosophical logic. This clear and accessible book investigates the forms of thought, drawing out and focusing on the central logical notions of reference, predication, identity, modality and conditionality. It will be useful to students and other interested readers in epistemology and metaphysics, philosophy of mind and language, and philosophical logic. (shrink)

It seems undeniable that we have many items of modal knowledge. Tradition has it that conceivability is the evidence for possibility that gets us to this modal knowledge. But "conceive" cannot mean think, understand, entertain, suppose, or find believable, because none of these are suited to serve as evidence for possibility, and if it is none of these, it is mysterious what conceivability is, and why it is evidence for possibility. I argue that sensory imagination is the most promising candidate (...) for a source of modal evidence. A theory of imaginative content is developed in Chapter One, one which allows what seems undeniable: that we do imagine the impossible. This raises a challenge to explain why, in the face of our ability to imagine the impossible, we should accept imagination as modal evidence. The predominant response, developed by Saul Kripke, limits the scope of imagination to preserve the link between imagination and what is possible. In Chapter Two I argue that the Kripkean theory is best thought of as an error theory: when we take ourselves to imagine, e.g., water without H2O, or Mark Twain and Sam Clemens in a fistfight, we are mistaken. I articulate and defend an alternative modal epistemology, one that exploits the crucial difference between assigned and basic content of imagining. The evidential value of some imaginings is undermined by independent considerations about the connection between assigned content and ignorance. Instances in which we imagine the impossible are all cases where these independent considerations give us reason to doubt the imagining's value as modal evidence. The conclusions about assigned content are applied in Chapter Three to the first-person imaginings thought to be crucial in philosophy of mind: the imaginability of zombies, and the imaginability of being a disembodied soul. It is argued that such imaginings offer no evidence favoring dualism over materialism. Finally, alternatives to imagination as the source for modal evidence are discussed in Chapter Four. I explore both direct intuition and a priori-based accounts, and conclude that neither offers a genuine alternative to the imagination. (shrink)

The epistemology of essence is a topic that has received relatively little attention, although there are signs that this is changing. The lack of literature engaging directly with the topic is probably partly due to the mystery surrounding the notion of essence itself, and partly due to the sheer difficulty of developing a plausible epistemology. The need for such an account is clear especially for those, like E.J. Lowe, who are committed to a broadly Aristotelian conception of essence, whereby essence (...) plays an important theoretical role. In this chapter, our epistemic access to essence is examined in terms of the a posteriori vs. a priori distinction. The two main accounts to be contrasted are those of David S. Oderberg and E.J. Lowe. (shrink)

In recent work, E. J. Lowe presents an essence-based account of our knowledge of metaphysical modality that he claims to be superior to its main competitors. I argue that knowledge of essences alone, without knowledge of a suitable bridge principle, is insufficient for knowing that something is metaphysically necessary or metaphysically possible. Yet given Lowe's other theoretical commitments, he cannot account for our knowledge of the needed bridge principle, and so his essence-based modal epistemology remains incomplete. In addition to that, (...) Lowe's account implies a psychologically unrealistic reconstruction of how we ordinarily acquire knowledge of metaphysical modalities. The discussion of Lowe's suggestive essence-based account is also intended as a case study that illustrates a more general problem in the epistemology of modality: the great difficulty of explaining our modal knowledge in terms of a single overtly nonmodal kind of knowledge. The failure of Lowe's account suggests that such a sweeping reductive explanation of our modal knowledge might simply not be available. This should be good news for those philosophers who champion less reductive or more pluralistic accounts of our modal knowledge. (shrink)

" Notre époque ne veut croire qu'à des "réalités". Or sa réalité la plus puissante est la science, voilà pourquoi c'est de la science philosophique dont notre époque a le plus grand besoin (...) et le plus grand progrès que puisse accomplir notre époque sera de reconnaître que l'intuition philosophique bien comprise est l'appréhension phénoménologique des essences.

Husserl cherche à dépasser l'opposition (...) toujours actuelle entre positivisme et historicisme, en exigeant que la philosophie s'établisse à partir d'un nouveau commencement, plus radical que tous ceux qu'elle n'a jamais pu entreprendre, et qu'elle vise une rigueur qui l'affranchisse enfin des modèles hérités des sciences de la nature. Quelle qu'ait été l'histoire de la phénoménologie Husserlienne, l'exigence exprimée dans ce manifeste ne concerne pas seulement un courant de pensée particulier ; elle est consubstantielle à la réflexion philosophique elle-même.

A personal view is presented of how metaphysics and ontology stand at the beginning of the twenty-first century, in the light of developments during the twentieth. It is argued that realist metaphysics, with serious ontology at its heart, has a promising future, provided that its adherents devote some time and effort to countering the influences of both its critics and its false friends.

The work on prototypes in ontologies pioneered by Rosch [10] and elaborated by Lakoff [8] and Freund [3] is related to vagueness in the sense that the more remote an instance is from a prototype the fewer people agree that it is an example of that prototype. An intuitive example is the prototypical “mother”, and it is observed that more specific instances like ”single mother”, “adoptive mother”, “surrogate mother”, etc., are less and less likely to be classified as “mothers” by (...) experimental subjects. From a different direction Gärdenfors [4] provided a persuasive account of natural predicates to resolve paradoxes of induction like Goodman’s “Grue” predicate [5]. Gärdenfors proposed that “quality dimensions” arising from human cognition and perception impose topologies on concepts such that the ones that appear “natural” to us are convex in these topologies. We show that these two cognitive principles — prototypes and predicate convexity — are equivalent to unimodal (convex) fuzzy characteristic functions for sets. Then we examine the case when the fuzzy set characteristic function is not convex, in particular when it is multi-modal. We argue that this is an indication that the fuzzy concept should really be regarded as a super concept in which the decomposed components are subconcepts in an ontological taxonomy. (shrink)

The common thought that Husserl was committed to a Platonist ontology of essences, and to a mysterious epistemology that holds that we can ‘intuit’ these essences, has contributed substantially to his work being dismissed and marginalized in analytic philosophy. This paper aims to show that it is misguided to dismiss Husserl on these grounds. First, the author aims to explicate Husserl’s views about essences and how we can know them, in ways that make clear that he is (...) not committed to a traditional Platonism, or a mystical epistemology. Second, the author argues that Husserl’s approach was an important source for Carnap in “Empiricism, Semantics, and Ontology”, where Carnap tried to overcome the empiricists’ qualms about referring to abstracta. Finally, the author will argue that Husserl’s approach can be reconstructed in contemporary analytic terms by appeal to the idea of pleonastic transformations. By seeing both Husserl’s views and their influences on later analytic work more clearly, the hope is to build bridges and make clear that the approach is of lasting value and interest. (shrink)

Modal epistemologies that rely on a fallibilism about modal claims have been gaining traction over the years. This paper critically discusses the accounts of Kung (2009, 2010, 2016) and Dohrn (2018, 2019, 2020b) and argues that they are invariably susceptible to being read as entailing claims of epistemic possibility. Both Kung and Dohrn seek to ground modal intuitions on non‐modal ones, and primarily appeal to the modalizing capacity of imagination to aid in the discovery of modal truths. However, insofar as (...) inference from non‐modal imagination to modal truths remains fallible, then no non‐ad hocdistinction can be made between substantiation of fallible metaphysically modal claims and infallible epistemically modal ones. This is because, barring an agent's infallible knowledge of modal truths, how these truths are argued for must attend the agent's imperfect epistemic access thereof, therefore entailing claims of modality consistent with her epistemic state—that is, claims of epistemic possibility. If modal epistemologies in general non‐modally ground their modal assertions in this fallible fashion, then they seem inevitably interpretable in terms of epistemic possibility as opposed to some non‐epistemic reading of metaphysical possibility.

E. J. Lowe offers an account of modal knowledge that involves two primary theses. First, the basis of modal knowledge is essential knowledge, and the source of essential knowledge is grasp of essence. Second, all empirical knowledge ultimately depends on some modal knowledge. This article assesses Lowe’s account and defends four conclusions. First, there is a tension in Lowe’s account of grasp of essence; it wavers between an undemanding version, which holds that grasp of essence requires no more than our (...) ordinary understanding of propositions, and a more demanding version, which holds that it requires rational insight into necessary relationships between essences. Second, both versions face serious challenges. Third, Lowe’s account of knowledge of essence does not provide a basis for modal knowledge. Fourth, Lowe’s supporting argument for his second thesis contains two significant gaps and the principles necessary to close the gaps reveal further tensions in his epistemological views. (shrink)

What is our epistemic access to metaphysical modality? Timothy Williamson suggests that the epistemology of counterfactuals will provide the answer. This paper challenges Williamson's account and argues that certain elements of the epistemology of counterfactuals that he discusses, namely so called background knowledge and constitutive facts, are already saturated with modal content which his account fails to explain. Williamson's account will first be outlined and the role of background knowledge and constitutive facts analysed. Their key role is to restrict our (...) imagination to rule out irrelevant counterfactual suppositions. However, background knowledge turns out to be problematic in cases where we are dealing with metaphysically possible counterfactual suppositions that violate the actual laws of physics. As we will see, unless Williamson assumes that background knowledge corresponds with the actual, true laws of physics and that these laws are metaphysically necessary, it will be difficult to address this problem. Furthermore, Williamson's account fails to accommodate the distinction between conceivable yet metaphysically impossible scenarios, and conceivable and metaphysically possible scenarios. This is because background knowledge and constitutive facts are based strictly on our knowledge of the actual world. Williamson does attempt to address this concern with regard to metaphysical necessities – as they hold across all possible worlds – but we will see that even in this case the explanation is questionable. These problems, it will be suggested, cannot be addressed in a counterfactual account of the epistemology of modality. The paper finishes with an analysis of Williamson's possible rejoinders and some discussion about the prospects of an alternative account of modal epistemology. (shrink)

L’une des tâches de la phénoménologie transcendantale, que Husserl lui-même définit comme une science éidétique des phénomènes transcendentalement réduits, est de découvrir des lois a priori matérielles d’un type spécial : des lois éidétiques descriptives établies sur la base de concepts descriptifs purs. Cet article s’attache d’abord à préciser la notion husserlienne d’essence au le sens large, définie comme une fonction d’état-de-choses (Sachverhaltsfunktion) ; une telle fonction noématique est le corrélat « objectif » de cette fonction propositionnelle que nous (...) appelons « concept » et qui est une partie de la proposition, c’est-à-dire de la visée-d’état-de-choses (Sachverhaltsmeinung) par laquelle on projette un état-de-choses. En revanche, par essences au sens étroit ou strict on entend ces essences pures que Husserl appelle « Eide ». Le concept d’essence pure propre à l’éidétique descriptive phénoménologique est ainsi clarifié par une explication de la notion husserlienne de « concept descriptif pure », dans le but de montrer comment ces concepts, qui sont des pures concepts de types, se distinguent des concept descriptifs impures, et notamment des concepts dénotant des genres naturels. Fondées exclusivement sur des concepts descriptifs purs, les lois éidétiques descriptives (Wesensgesetze) possèdent des conditions de vérités particulières et nécessitent de modalités d’examen tout autant spécifiques. La place propre à la méthode appelée « variation éidétique » est justement celle de examiner, falsifier ou justifier des lois éidétiques descriptives présumées. A partir de cas exemplaires d’états-de-choses familiers confirmant les lois présumées, la variation libre, qui opère dans la pure imagination, a pour tâche de construire des contre-exemples possibles dont le but est de falsifier la loi éidétique présumée. La propriété d’être falsifiable par des contre-exemples construits dans la pure imagination permet de distinguer les lois empiriques des lois éidétiques descriptives de l’éidétique husserlienne. La possibilité de falsifier par des contre-exemples fictionnels ou factuels montre que la phénoménologie transcendantale est une entreprise scientifique ouverte à l’examen intersubjectif, et cela justement en raison de son caractère éidétique.

Assertions about metaphysical modality play central roles in philosophical theorizing. For example, when philosophers propose hypothetical counterexamples, they often are making a claim to the effect that some state of affairs is possible. Getting the epistemology of modality right is thus important. Debates have been preoccupied with assessing whether imaginability—or conceivability, insofar as it’s different—is a guide to possibility, or whether it is rather intuitions of possibility—and modal intuitions more generally—that are evidence for possibility claims. The dissertation argues that the (...) imagination plays a subtler role than the first view recognizes, and a more central one than the second view does. In particular, it defends an epistemology of metaphysical modality on which someone can acquire modal knowledge in virtue of having performed certain complex imaginative exercises. (shrink)

Claims concerning what is or is not possible abound in contemporary philosophy. The epistemology of such claims, however, remains largely unexplored. Anything imaginable is possible, we are told, with the proviso that imagination be governed by logic. Many who defend this methodology argue that logic frees us from recourse to some mysterious a priori faculty of intuition. Anything is possible so long as it does not contain a contradiction—and we don’t need intuition to tell us what is contradictory, just logic. (...) Logic is thus supposed to provide us with a non-mysterious, intuition-free, modal epistemology. The purpose of this paper is to argue that logic does not deliver on this promise. The argument proceeds along two fronts. First, I argue that logic is not sufficient for the task. Not only are there consistent but impossible propositions, there are even inconsistent propositions that are possible. Second, and more fundamentally, I question the epistemic independence of appeals to logical consistency. I will argue that in judging a proposition to be consistent we rely upon our intuitions concerning what is possible. In other words, our modal beliefs undergird our judgments about consistency and not vice-versa. (shrink)

In this chapter, it is suggested that our epistemic access to metaphysical modality generally involves rationalist, a priori elements. However, these a priori elements are much more subtle than ‘traditional’ modal rationalism assumes. In fact, some might even question the ‘apriority’ of these elements, but I should stress that I consider a priori and a posteriori elements especially in our modal inquiry to be so deeply intertwined that it is not easy to tell them apart. Supposed metaphysically necessary identity statements (...) involving natural kind terms are a good example: the fact that empirical input is crucial in establishing their necessity has clouded the role and content of the a priori input, as I have previously argued. For instance, the supposed metaphysically necessary identity statement involving water and its microstructure can only be established with the help of a controversial a priori principle concerning the determination of chemical properties by microstructure. The Kripke-Putnam framework of modal epistemology fails precisely because it is unclear whether the required a priori element is present. My positive proposal builds on E. J. Lowe’s work. Lowe holds that our knowledge of metaphysical modality is based on our knowledge of essence. Lowe’s account strives to offer a uniform picture of modal epistemology: essence is the basis of all our modal knowledge. This is the basis of Lowe’s modal rationalism. I believe that Lowe’s proposal is on the right lines in the case of abstract objects, but I doubt that it can be successfully applied to the case of natural kinds. Accordingly, the case of natural kinds will be my main focus and I will suggest that modal rationalism, at least as it is traditionally understood, falls short of explaining modal knowledge concerning natural kinds. Yet, I think that Lowe has identified something of crucial importance for modal epistemology, namely the essentialist, a priori elements present in our modal inquiry. The upshot is that rather than moving all the way from modal rationalism to modal empiricism, a type of hybrid approach, ‘empirically-informed modal rationalism ’, can be developed. (shrink)

Hale has argued that logical necessities are absolute in the sense that there is no competing kind of modality under which they may be false. In this paper, I argue that there are competing kinds of modality, which I call “essentialist modalities,” under which logical necessities may be false. Since it is counter-intuitive to say that logical necessities are not absolute, my argument, if correct, shows that Hale’s characterization of absolute necessity does not adequately capture the intuitive notion of absolute (...) necessity. Then, a qualified version of Hale’s characterization of absolute necessity is proposed. On the qualified version, the absoluteness of logical necessities is no longer defeated by essentialist possibilities. (shrink)

What is the relationship between ontology and modality - between what there is, and what there could be, must be, or might have been? Bob Hale interwove these two strands of metaphysics throughout his long and distinguished career, putting forward his theses in his book, Necessary Beings: An Essay on Ontology, Modality, and the Relations Between Them (OUP 2013). Hale addressed questions of ontology and modality on a number of fronts: through the development of a Fregean approach to ontology, an (...) essentialist theory of modality, and in his work on neo-logicism in the philosophy of mathematics. The essays in this volume engage with these themes in Hale's work in order to progress our understanding of ontology, modality, and the relations between them. Some directly address questions in modal metaphysics, drawing on ontological concerns, while others raise questions in modal epistemology and of its links to matters of ontology, such as the challenge to give an epistemology of essence. Several essays also engage with questions of what might be called 'modal ontology': the study of whether and what things exist necessarily or contingently. Such issues have an important bearing on the kinds of semantic commitments engendered in logic and mathematics (to the existence of sets, or numbers, or properties, and so on) and the extent to which one's ontology of necessary beings interacts with other plausible assumptions and commitments.

It is thus explored in some chapters to what extent one’s ontology—and indeed, one’s ontology of necessary beings—interacts with other plausible assumptions and commitments. (shrink)

Charles Peirce's diagrammatic logic — the Existential Graphs — is presented as a tool for illuminating how we know necessity, in answer to Benacerraf's famous challenge that most ‘semantics for mathematics’ do not ‘fit an acceptable epistemology’. It is suggested that necessary reasoning is in essence a recognition that a certain structure has the particular structure that it has. This means that, contra Hume and his contemporary heirs, necessity is observable. One just needs to pay attention, not merely to individual (...) things but to how those things are related in larger structures, certain aspects of which relations force certain other aspects to be a certain way.

For Spinoza’s epistemology, an image is an idea that represents an external body as actually existent. This kind of knowledge is the only source of inadequate knowledge, falsity, and error. On the contrary, reason is adequate knowledge because it comprehends common notions, i.e, properties of different things. Intuition is also adequate knowledge because it conceives formal essences of singular things. The main example is the genetic definition of a sphere, an adequate knowledge form by the power of thinking of the (...) mind, without regard to existing extramental spheres. From these differences, some scholars conclude that imagination is always negative and should not deal with reason and intuition. But this conclusion will ban Spinoza’s epistemology from having adequate knowledge of existing individuals, such as Moses and the Hebrew State. In front of this view, this paper defends three theses: firstly, that the difference between the three kinds of knowledge is of genus, not of degree. Secondly, that adequate knowledge for Spinoza is a generic knowledge, i.e., insofar as S knows P insofar S deduces the effects, consequences, or properties of P. Thirdly, that adequate knowledge can include imagination through the proper use of the geometric method. In this case, imagination offers data to reason and intuition for having adequate knowledge of singular things that actually existed. (shrink)

Modal epistemology has been dominated by a focus on establishing an account either of how we have modal knowledge or how we have justified beliefs about modality. One component of this focus has been that necessity and possibility are basic access points for modal reasoning. For example, knowing that P is necessary plays a role in deducing that P is essential, and knowing that both P and ¬P are possible plays a role in knowing that P is accidental. Chalmers (2002) (...) and Williamson (2007) provide two good examples of contrasting views in modal epistemology that focus on providing an account of modal knowledge where necessity and possibility are basic access points for modal knowledge, and Yablo (1993) provides a good account of how we have justified beliefs about modality. In contrast to this tradition I argue for and outline a modal epistemology based on objectual understanding and essence, rather than knowledge or justification and necessity and possibility. The account employs a non-modal conception of essence and takes objectual understanding of essence, rather than knowledge of essence to be basic in modal reasoning. I begin by articulating Kvanvig’s (2003) account of objectual understanding, on which objectual understanding of Φ is not equivalent to propositional knowledge of Φ. I then argue that an epistemology of essence that uses property variation-in-imagination is better construed as a model that delivers objectual understanding of essence rather than knowledge of essence. I argue that this is so, since the latter and not the former runs into a version of the Meno paradox. I show how this account can be applied to two issues in modal epistemology: the Benacerraf problem for modality, and the architecture of modal knowledge. (shrink)

Vaidya has recently argued that while Husserl’s method for acquiring knowledge of essence through use of our imagination is subject to a vicious epistemic circle, we can still use the method to successfully attain objectual understanding of essence. In this paper, I argue that the Husserlian objectual understanding-based epistemology envisaged by Vaidya suffers from a similar epistemic circularity as its knowledge-based foil. I argue that there is a straight-forward solution to this problem, but then raise three serious problems for (...) an amended version of Vaidya’s proposal and any similar Husserlian epistemology of essence. The paper closes with some general reflections on applying the Husserlian method to the contemporary notion of essence and on the idea of refocusing the epistemology of essence on understanding instead of knowledge.

Over a period of several decades spanning the origin of the Vienna Circle, Schlick repeatedly attacked Husserl''s phenomenological method for its reliance on the ability to intuitively grasp or see essences. Aside from its significance for phenomenologists, the attack illuminates significant and little-explored tensions in the history of analytic philosophy as well. For after coming under the influence of Wittgenstein, Schlick proposed to replace Husserl''s account of the epistemology of propositions describing the overall structure of experience with his (...) own account based on the structure of language rather than on the intuition of essences. I discuss both philosophers'' accounts of the epistemology of propositions describing the structure of experience. For both philosophers, this epistemology was closely related to the general epistemology of logic; nevertheless, neither philosopher had a completely coherent account of it. Comparison of the two approaches shows that perennial and severe theoretical obstacles stand in the way of giving an epistemology of the structure of experience, a central requirement for both philosophers'' theories. Consideration of these obstacles sheds a new light on the reasons for the historically decisive split between the continental and the analytic traditions, as well as on the subsequent development of the analytic tradition away from the structural description of experience.

Philosophers have recently highlighted substantial affinities between causation and grounding, which has inclined some to import the conceptual and formal resources of causal interventionism into the metaphysics of grounding. The prospect of grounding interventionism raises two important questions: exactly what are grounding interventions, and why should we think they enable knowledge of grounding? This paper will approach these questions by examining how causal interventionists have addressed (or might address) analogous questions and then comparing the available options for grounding interventionism. I (...) argue that grounding interventions must be understood in worldly terms, as adding something to or deleting something from the roster of entities, or making some fact obtain or fail to obtain. I consider three bases for counterfactual assessment: imagination, structural equation models, and background theory. I conclude that grounding interventionism requires firmer epistemological foundations, without which the interventionist's epistemology of grounding is incomplete and ineffectually rationalist.
