BonJour has proposed background conditions on internalist justification, which Kornblith argues are inconsistent with a core internalist ‘credo’ – that subjects internally alike are justificationally alike – signaling the ‘death’ of internalism. The funeral arrangements are premature, though more systematic consideration of background conditions is needed. The majority of BonJour's conditions are not background conditions as their failure makes an epistemically relevant internal difference. This neutralizes Kornblith's criticisms and reveals how the proposed conditions are not departures from internalism. BonJour's background (...) conditions are simply conditions, the credo remains intact, and Kornblith's objections do not spell problems for internalism, let alone death. (shrink)

This is the second in a series of two articles that serve as an introduction to recent debates about cognitive phenomenology. Cognitive phenomenology can be defined as the experience that is associated with cognitive activities, such as thinking, reasoning, and understanding. What is at issue in contemporary debates is not the existence of cognitive phenomenology, so defined, but rather its nature and theoretical role. The first article examines questions about the nature of cognitive phenomenology, while the second article explores the (...) philosophical implications of these questions for the role of consciousness in theories of intentionality, introspective self-knowledge, and knowledge of the external world.

Does rationality require logical omniscience? Our best formal theories of rationality imply that it does, but our ordinary evaluations of rationality seem to suggest otherwise. This paper aims to resolve the tension by arguing that our ordinary evaluations of rationality are not only consistent with the thesis that rationality requires logical omniscience, but also provide a compelling rationale for accepting this thesis in the first place. This paper also defends an account of apriori justification for logical beliefs that is designed (...) to explain the rational requirement of logical omniscience. On this account, apriori justification for beliefs about logic has its source in logical facts, rather than psychological facts about experience, reasoning, or understanding. This account has important consequences for the epistemic role of experience in the logical domain. In a slogan, the epistemic role of experience in the apriori domain is not a justifying role, but rather an enabling and disabling role. (shrink)

This essay reconsiders Davidson's critical attribution of the scheme‐content distinction to Quine's naturalized epistemology. It focuses on Davidson's complaint that the presence of this distinction leads Quine to mistakenly construe neural input as evidence. While committed to this distinction, Quine's epistemology does not attempt to locate a justificatory foundation in sensory experience and does not then equate neural intake with evidence. Quine's central epistemological task is an explanatory one that attempts to scientifically clarify the route from stimulus to science. Davidson's (...) critical remarks wrongly assign concerns to Quine's view that it does not have and further obscures the status of his naturalized conception of epistemology. (shrink)

An argument is epistemically self-defeating when either the truth of an argument’s conclusion or belief in an argument’s conclusion defeats one’s justification to believe at least one of that argument’s premises. Some extant defenses of the evidentiary value of intuition have invoked considerations of epistemic self-defeat in their defense. I argue that there is one kind of argument against intuition, an unreliability argument, which, even if epistemically self-defeating, can still imply that we are not justified in thinking intuition has evidentiary (...) value.

The debate concerning the role of intuitions in philosophy has been characterized by a fundamental disagreement between two main camps. The first, the autonomists, hold that, due to the use in philosophical investigation of appeals to intuition, most of the central questions of philosophy can in principle be answered by philosophical investigation and argument without relying on the sciences. The second, the naturalists, deny the possibility of a priori knowledge and are skeptical of the role of intuition in providing evidence (...) in philosophical inquiry. In spite of the seemingly stark and deep disagreement between the autonomist and the naturalist, in this paper I will attempt to suggest that there is a way to mount a partial defense of intuition-based philosophical practice on naturalist grounds. As will be seen, doing so will require a number of concessions that will satisfy few autonomists while simultaneously disappointing those naturalists who might have thought that all notions of the a priori had been successfully laid to rest. However, I will argue that the account proposed here will preserve those features of traditional philosophical practice that matter most and better explain the history of successes and failures of that practice, thus answering the worries of the autonomist, and that the rejection of the No A Priori Thesis attendant with the account presented here is indeed demanded by the current theories of our best scientific understanding of the mind, thus pacifying the rabid naturalistic critic of any version of apriorism.

It would be nice if good old a priori conceptual analysis were possible. For many years conceptual analysis was out of fashion, in large part because of the excessive ambitions of verificationist theories of meaning._ _However, those days are over._ _A priori conceptual analysis is once again part of the philosophical mainstream._ _This renewed popularity, moreover, is well-founded. Modern philosophical analysts have exploited developments in philosophical semantics to formulate analyses which avoid the counterintuitive consequences of verificationism, while vindicating our ability (...) to know a priori precisely what it is our words and thoughts represent._ _Despite its apparent promise, however, I.

The epistemology of modality is gradually coming to play a central role in general discussions about modality. This paper is a contribution in this direction, in particular I draw a comparison between Lewis’s Modal realism and Timothy Williamson’s recent account of modality in terms of counterfactual thinking. In order to have criteria of evaluation, I also formulate four requirements which are supposed to be met by any theory of modality to be epistemologically adequate.

In various arguments, Descartes relies on the principles that conceivability implies possibility and that inconceivability implies impossibility. Those principles are in tension with another Cartesian view about the source of modality, i.e. the doctrine of the free creation of eternal truths. In this paper, I develop a ‘two-modality’ interpretation of the doctrine of eternal truths which resolves the tension and I discuss how the resulting modal epistemology can still be relevant for the contemporary discussion.

My primary goal in this paper is to defend the plausibility of Kripke’s thesis that there are contingent a priori truths, and to fill out some gaps in Kripke’s own account of these truths. But the strategy here adopted is, to the best of my knowledge, still unexplored and different from the one adopted both by Kripke himself and by his critics. I first argue that Kripke’s examples of such truths can only be legitimate if seen as introduced by performative (...) utterances sense). And, if this is so, we can apply the machinery of illocutionary act theory to these utterances to explain how one can have a priori knowledge of some contingent facts generated by the utterances themselves. I shall argue that the overall strategy can fill out two gaps in Kripke’s original account: first, we can explain the nature of the truth-makers of contingent a priori truths sense, broadly conceived) and, second, we can explain how contingent a priori knowledge can be transmitted from one speaker to another.

Whether educational research should employ the ‘scientific method’ has been a recurring issue in its history. Hence, textbooks on research methods continue to perpetuate the idea that research students ought to choose between competing camps: ‘positivist’ or ‘interpretivist’. In reference to one of the most widely referred to educational research methods textbooks on the market—namely Research Methods in Education by Cohen, Manion, and Morrison—this paper demonstrates the misconception of science in operation and the perversely false dichotomy that has become enshrined (...) in educational research. It then advocates a new approach, and suggests that the fixation with ‘science’ versus ‘non-science’ is counterproductive, when what is actually required for good inquiry is a critical approach to knowledge claims.

This paper shows that so-called ‘threshold concepts’ have been defined in a way that makes it impossible, even in principle, to empirically isolate them. It continues by proposing an alternative theoretical framework, and argues: (1) that concepts are not reducible to abilities; (2) that acquisition of a given concept can be necessary, but not sufficient, for the possession of an ability; and (3) that being ‘threshold’ is an extrinsic property, such that what is threshold for one person is not for (...) another. It closes by outlining two resultant problems for related empirical research. First, how is it possible to test for concepts, rather than abilities? Second, how can we tell if there is more than one possible conceptual route to the same ability? (shrink)

Philip Kitcher has argued against the apriority of mathematical knowledge in a number of places. His arguments rely on a conception of mathematical knowledge as embedded in a historical tradition and the claim that this sort of embedding compromises apriority. In this paper, I argue that tradition dependence of mathematical knowledge does not compromise its apriority. I further identify the factors which appear to lead Kitcher to argue as he does.

It is commonplace in cognitive science that concepts are individuated in terms of the roles they play in the cognitive lives of thinkers, a view that Jerry Fodor has recently been dubbed ‘Concept Pragmatism’. Quinean critics of Pragmatism have long argued that it founders on its commitment to the analytic/synthetic distinction, since without such a distinction there is plausibly no way to distinguish constitutive from non-constitutive roles in cognition. This paper considers Fodor’s empirical arguments against analyticity, and in particular his (...) arguments against lexical decomposition and definitions, and argues that Concept Pragmatists have two viable options with respect to them. First, Concept Pragmatists can confront them head-on, and argue that they do not show that lexical items are semantically primitive or that lexical concepts are internally unstructured. Second, Pragmatists may accept that these arguments show that lexical concepts are atomic, but insist that this need not entail that Pragmatism is false. For there is a viable version of Concept Pragmatism that does not take lexical items to be semantically structured or lexical concepts to be internally structured. Adopting a version of Pragmatism that takes meaning relations to be specified by inference rules, or meaning postulates, allows one to accept the empirical arguments in favor of Concept Atomism, while at the same time deny that such arguments show that there are no analyticities. The paper concludes by responding to Fodor’s recent objection that such a version of Concept Pragmatism has unhappy consequences concerning the relation between concept constitution and concept possession.

Recognitional concepts have the following characteristic property: thinkers are disposed to apply them to objects merely on the basis of undergoing certain perceptual experiences. I argue that a prominent strategy for defending the existence of constitutive connections among concepts, which appeals to thinkers’ semantic-cum-conceptual intuitions, cannot be used to defend the existence of recognitional concepts. I then outline and defend an alternative argument for the existence of recognitional concepts, which appeals to certain psychological laws.

This paper discusses Plato’s question from the Meno : Why should we prefer knowledge that p over mere true belief that p? I find I just do prefer knowledge, and not for any further benefit that I am aware of in the particular case. But I should have that preference, because given our practice of approving of testimony only if uttered with knowledge, I could fail to prefer knowledge, when other things seem to me to be equal, only by having (...) the sorts of serious social or psychological defects that would make me unresponsive to the approval of others. Finally, the social practice that produces this particular preference is good for all of us because it improves the average quality of the testimony we receive, which results in greater success in our projects.

Adequate epistemic justification is best conceived as the appearance, over time, of knowledge to the subject. ‘Appearance’ is intended literally, not as a synonym for belief. It is argued through consideration of examples that this account gets the extension of ‘adequately justified belief’ at least roughly correct. A more theoretical reason is then offered to regard justification as the appearance of knowledge: If we have a knowledge norm for assertion, we do our best to comply with this norm when we (...) express as assertions only beliefs that appear to us to be knowledge. If we are doing our best, there is little point in further sanctions. So a norm of knowledge for assertion would lead to a secondary norm of justified belief as the appearance of knowledge, marking a point at which our assertions may be corrected but should not be blamed.

One would have thought that Fodor's justly famous computational views about the mind and his covariation approaches to content owed a lot to the twentieth century that he now reviles. On the other hand, a number of lines he pursues in the target article make one wonder whether he hasn’t perhaps changed his mind about those famous views. Specifically, I argue that his own theory of content is open to the very same objections he raises against ‘sorting’ theories, and that (...) the supposed circularity in implicit definitions of logical particles can easily be avoided by the very functional/computational definitions that he fathered decades ago. Fodor's rejection here of sorting and implicit definition does make one worry that he is now opting for what seems the only atomistic alternative that would seem to be left, the first‐person meaning mysticism of the very Cartesian sort he now claims to favor, but from which I would have thought twentieth century role and discrimination views were a welcome relief. Despite all these worries, however, I concede that one could probably do worse than assume for the nonce that meaning is atomic, or, anyway, unanalyzed, and get on with investigating the mind on that basis—but keeping the options open.

Although radical forms of relativism are perhaps beyond the epistemological pale, I argue here that a more moderate form may be plausible, and articulate the conditions under which moderate epistemic relativism could well serve our epistemic goals. In particular, as a result of our limitations as human cognizers, we find ourselves needing to investigate the dappled and difficult world by means of competing communities of highly specialized researchers. We would do well, I argue, to admit of the existence of unresolvable (...) disputes between such communities, but only so long as there is a sufficient amount of fruitful exchange between them as well. I close with some speculation about when it is or is not legitimate to make an “appeal to discipline”: responding to another’s argument by saying something like, “we should do it this way, because we are philosophers (/linguists/psychologists/…), and that’s just what we do”.

Although recent epistemology has been marked by several prominent disagreements – e.g., between foundationalists and coherentists, internalists and externalists – there has been widespread agreement that some form of fallibilism must be correct. According to a rough formulation of this view, it is possible for a subject to have knowledge even in cases where the justification or grounding for the knowledge is compatible with the subject’s being mistaken. In this paper, I examine the motivation for fallibilism before providing a fully (...) general account of the view. I conclude by looking at the two major difficulties for fallibilism: the Gettier problem and the lottery paradox. (shrink)

Instability occurs when the very fact of choosing one particular possible option rather than another affects the expected values of those possible options. In decision theory: An act is stable iff given that it is actually performed, its expected utility is maximal. When there is no stable choice available, the resulting instability can seem to pose a dilemma of practical rationality. A structurally very similar kind of instability, which occurs in cases of anti-expertise, can likewise seem to create dilemmas of (...) epistemic rationality. One possible line of response to such cases of instability, suggested by both Jeffrey (1983) and Sorensen (1987), is to insist that a rational agent can simply refuse to accept that such instability applies to herself in the first place. According to this line of thought it can be rational for a subject to discount even very strong empirical evidence that the anti-expertise condition obtains. I present a new variety of anti-expertise condition where no particular empirical stage-setting is required, since the subject can deduce a priori that an anti-expertise condition obtains. This kind of anti-expertise case is therefore not amenable to the line of response that Jeffrey and Sorensen recommend. (shrink)

Moderate rationalists maintain that our rational intuitions provide us with prima facie justification for believing various necessary propositions. Such a claim is often criticized on the grounds that our having reliable rational intuitions about domains in which the truths are necessary is inexplicable in some epistemically objectionable sense. In this paper, I defend moderate rationalism against such criticism. I argue that if the reliability of our rational intuitions is taken to be contingent, then there is no reason to think that (...) our reliability is inexplicable. I also suggest that our reliability is, in fact, necessary, and that such necessary reliability neither admits of, nor requires, any explanation of the envisaged sort. (shrink)

Something about this argument sounds funny. As we’ll see, though, it takes some care to identify exactly what Moore has done wrong. Iwill assume that Moore knows premise (2) to be true. One could inquire into how he knows it, and whether that knowledge can be defeated; but Iwon’t. I’ll focus instead on what epistemic relations Moore has to premise (1) and to his conclusion (3). It may matter which epistemic relations we choose to consider. Some philosophers will diagnose Moore’s (...) argument using Contextualist machinery. They’ll say. (shrink)

I argue that beliefs that are true whenever held-like I exist, I am thinking about myself, and (in an object-dependent framework) Jack = Jack-needn't on that account be a priori. It does however seem possible to remove the existential commitment from the last example, to get a belief that is knowable a priori. I discuss some difficulties concerning how to do that.

Hume argued that inductive inferences do not have rational justification. My aim is to reject Hume's argument. The discussion is partly motivated by an analogy with Carroll's Paradox, which concerns deductive inferences. A first radically externalist reply to Hume is that justified inductive inferences do not require the subject to know that nature is uniform, though the uniformity of nature is necessary condition for having the justification. But then the subject does not have reasons for believing what she believes. I (...) defend a moderate externalist account that seeks to partly accommodate that objection to the radical externalist proposal. It is based on an extension of Peacocke's theory of concepts: possession conditions for predicative concepts standing for natural properties include dispositions to project them to new cases in accordance with inductive inferential patterns.

A traditional view is that to be an empiricist is to hold a particular epistemological belief: something to the effect that knowledge must derive from experience. In his recent book The Empirical Stance, and in a number of other publications, Bas van Fraassen has disagreed, arguing that if empiricism is to be defensible it must instead be thought of as a stance: an attitude of mind or methodological orientation rather than a factual belief. In this article I will examine his (...) arguments for this claim in detail. I will argue that they do not succeed and that empiricism is, contrary to van Fraassen's claim, better thought of as a truth‐evaluable doctrine than as a stance. (shrink)

This article lays the groundwork for a defense of rational intuitions by first arguing against a prevalent view according to which intuition is a distinctive psychological state, an “intellectual seeming” that p, that then constitutes evidence that p. An alternative account is then offered, according to which an intuition that p constitutes non-inferential a priori knowledge that p in virtue of the concepts exercised in judging that p. This account of rational intuition as the exercise of conceptual capacities in a (...) priori judgment is then distinguished from the dogmatic, entitlement and reliabilist accounts of intuition’s justificatory force. The article concludes by considering three implications of the proposed view for the Experimental Philosophy movement. (shrink)

I defend a moderate externalist account that seeks to partly accommodate that objection to the radical externalist proposal.

In this paper I will argue that this entire dialectic is somewhat misguided. The mental states which are generally assumed to fall under the category of ‘intuition’ likely comprise a highly heterogeneous group; from the point of view of psychology or of neuroscience, in fact, ‘intuitions’ appear to be generated by several fundamentally different sorts of mental processes. If this is correct, then the term ‘intuition’ may simply carve things too broadly. I will argue that it is a mistake to (...) focus on the ‘reliability of intuition’; empirical evidence suggests that the reliability of one type of intuition may tell us next to nothing about the reliability of other types. Rather than debating the evidential status of intuition as a whole, philosophers interested in methodology would do well to focus their investigations much more narrowly. (shrink)

This is a very selective survey of developments in epistemology, concentrating on work from the past twenty years that is of interest to philosophers of science. The selection is organized around interesting connections between distinct themes. I first connect issues about skepticism to issues about the reliability of belief-acquiring processes. Next I connect discussions of the defeasibility of reasons for belief to accounts of the theory-independence of evidence. Then I connect doubts about Bayesian epistemology to issues about the content of (...) perception. The last detailed connection is between considerations of the finiteness of cognition and epistemic virtues. To connect the connections I end by briefly discussing the pressure that consideration of social roles in the transmission of belief puts on the purposes of epistemology. (shrink)

Self-defeating and self-justifying expressions are reflexive insofar as they pertain to themselves. However, the reflexivity involved is often pragmatic, i.e., does not entirely depend upon the logical properties of what is expressed but also upon the expressive act. In this paper I present a general account of pragmatic reflexivity and apply it to some familiar self-defeating and self-justifying expressions in epistemology. This application indicates some important, if often neglected features of the epistemological issues involved. The account I defend suggests that (...) epistemology is particularly sensitive to pragmatic reflexivity since what epistemologists do, i.e., inquire, theorize, and defend theories, is also the subject of the inquiry and resultant theories.

In this paper, I present counterexamples to the evidence thesis, the thesis that S knows that p at t only if S believes that p on the basis of evidence at t. The outline of my paper is as follows. In section 1, I explain the evidence thesis and make clear what a successful counterexample to the evidence thesis will look like. In section 2, I show that instances of non-occurrent knowledge are counterexamples to the evidence thesis. At the end (...) of section 2, I consider the primary thesis of my paper — that the evidence thesis is false — to be successfully defended. In section 3, I consider three variations of the evidence thesis. The first variation restricts the evidence thesis to occurrent knowledge; the second requires for knowledge that one’s belief could be based on evidence; and the third requires for knowledge that the belief was based on evidence at a suitable prior time. The secondary thesis of this paper is that these variations are also subject to serious objections. (shrink)

According to orthodox views of philosophical methodology, when philosophers appeal to intuitions, they treat them as evidence for their contents. Call this “descriptive evidentialism.” Descriptive evidentialism is assumed both by those who defend the epistemic status of intuitions and by those, including many experimental philosophers, who criticize it. This article shows, however, that the idea that philosophers treat intuitions as evidence struggles to account for the way philosophers treat intuitions in a variety of philosophical contexts. In particular, it cannot account (...) for philosophers' treatment of a priori intuitions, for nonpropositional uses of intuition, and for philosophers' failure to use intuition to exclude the counterintuitive. The article concludes that alternatives to descriptive evidentialism (some of which are sketched) must be developed, and that much of the recent debate between traditionalists and skeptics from, for example, experimental philosophy is probably based on a false presupposition.

In this paper, I argue that the method of cases (namely, the method of using intuitive judgments elicited by intuition pumps as evidence for and/or against philosophical theories) is not a reliable method of generating evidence for and/or against philosophical theories. In other words, the method of cases is unlikely to generate accurate judgments more often than not. This is so because, if perception and intuition are analogous in epistemically relevant respects, then using intuition pumps to elicit intuitive judgments is (...) like using illusions to elicit perceptual judgments. In both cases, judgments are made under bad epistemic circumstances. (shrink)

The paper is a critical examination of Peacocke’s pioneering work on concepts as grounding the possibility of a priori knowledge. It focuses upon his more recent turn to reference and referential domain, and the two enlargements of the purely conceptual bases for apriority, namely appeal to conceptions and to direct referential sensitivity. I argue that the two are needed, but they produce more problem for the strategy as a whole than they solve. I conclude by suggesting that they point to (...) a possible Benacerraf-like dilemma for conceptualist accounts of armchair knowledge: if concepts are akin to representational contents and/or conceptions, they certainly do not metaphysically determine anything. At best, they fallibly guide our inquiry and get corrected almost by each new important discovery about the nature of their referents. If what is meant by “concept” is a Fregean, objectively correct and metaphysically potent entity, there is little doubt in its power to determine its referent(s), but there is a huge epistemic problem of how we grasp such Platonic concepts. Peacocke’s early metaphysics of concept, which offered beginnings of an answer, is put in jeopardy by the new referential turn, and his valiant attempts to pass between the multiple horns of this dilemma seem to face a lot of difficulties.

Mathematical apriorists sometimes hold that our non-derived mathematical beliefs are warranted by mathematical intuition. Against this, Philip Kitcher has argued that if we had the experience of encountering mathematical experts who insisted that an intuition-produced belief was mistaken, this would undermine that belief. Since this would be a case of experience undermining the warrant provided by intuition, such warrant cannot be a priori.I argue that this leaves untouched a conception of intuition as merely an aspect of our ordinary ability to (...) reason. Thus the apriorist may still hold that some mathematical beliefs are warranted by intuition. (shrink)

Rational intuitions involve a particular form of understanding that gives them a special epistemic status. This form of understanding and its epistemic efficacy are not explained by several current theories of rational intuition, including Phenomenal Conservatism (Huemer, Skepticism and the veil of perception, 2001 ; Ethical intuitionism, 2005 ; Philos Phenomenol Res 74:30–55, 2007 ), Proper Functionalism (Plantinga, Warrant and proper function, 1993 ), the Competency Theory (Bealer Pac Philos Q 81:1–30, 2000 ; Sosa, A virtue epistemology, 2007 ) and (...) the Direct Awareness View (Conee, Philos Phenomenol Res 4:847–857, 1998 ; Bonjour, In defense of pure reason, 1998 ). Some overlook it; others try to account for it but fail. We can account for the role of understanding in rational intuition by returning to the view of some of the early Rationalists, e.g. Descartes and Leibniz. While that view carries a prohibitive cost, it does contain an insight that may help us solve the problem of giving understanding its due. (shrink)

Given the plethora of competing logical theories of validity available, it’s understandable that there has been a marked increase in interest in logical epistemology within the literature. If we are to choose between these logical theories, we require a good understanding of the suitable criteria we ought to judge according to. However, so far there’s been a lack of appreciation of how logical practice could support an epistemology of logic. This paper aims to correct that error, by arguing for a (...) practice-based approach to logical epistemology. By looking at the types of evidence logicians actually appeal to in attempting to support their theories, we can provide a more detailed and realistic picture of logical epistemology. To demonstrate the fruitfulness of a practice-based approach, we look to a particular case of logical argumentation—the dialetheist’s arguments based upon the self-referential paradoxes—and show that the evidence appealed to support a particular theory of logical epistemology, logical abductivism.

While anti-exceptionalism about logic is now a popular topic within the philosophy of logic, there’s still a lack of clarity over what the proposal amounts to. currently, it is most common to conceive of AEL as the proposal that logic is continuous with the sciences. Yet, as we show here, this conception of AEL is unhelpful due to both its lack of precision, and its distortion of the current debates. Rather, AEL is better understood as the rejection of certain traditional (...) properties of logic. The picture that results is not of one singular position, but rather a cluster of often connected positions with distinct motivations, understood in terms of their rejection of clusters of the various traditional properties. In order to show the fruitfulness of this new conception of AEL, we distinguish between two prominent versions of the position, metaphysical and epistemological AEL, and show how the two positions need not stand or fall together.

I discuss several problems for Williamson’s counterfactual-theory of modal knowledge and argue that they have a common source, in that the theory neglects to elucidate the proper constraints on modal reasoning. Williamson puts forward an empirical hypothesis that rests on the role of counterfactual reasoning for modal knowledge. But he overlooks central questions of normative modal epistemology. In order for counterfactual reasoning to yield correct beliefs about modality, it needs to be suitably constrained. I argue that what is needed is, (...) specifically, information concerning the nature or essence of things. By integrating this information, essentialist deduction arguably provides a better account of our knowledge of modality. Furthermore, I argue that essences have distinctive causal and explanatory powers—indeed, essences are superexplanatory for how things are. Compared to Williamson’s counterfactual-theory, superexplanatory essentialism clarifies what the proper constraints on modal reasoning are, and why they have such a special status. (shrink)

I propose that we approach the epistemology of modality by putting modal metaphysics first and, specifically, by investigating the metaphysics of essence. Following a prominent Neo-Aristotelian view, I hold that metaphysical necessity depends on the nature of things, namely their essences. I further clarify that essences are core properties having distinctive superexplanatory powers. In the case of natural kinds, which is my focus in the paper, superexplanatoriness is due to the fact that the essence of a kind is what causes (...) all the many properties and behaviors that are typically shared by all the instances of the kind. Accordingly, we know what is necessarily true of kinds by knowing what is essential to them in the sense of actually playing such causal-explanatory roles. Modal reasoning aimed at discovering metaphysical necessity thus proceeds via essentialist deduction: we move from essentialist truths to reach necessary truths. (shrink)
