This chapter argues that the general philosophy of science should learn metaphilosophical lessons from the case of metaphysical underdetermination, as it occurs in non-relativistic quantum mechanics. Section presents the traditional discussion of metaphysical underdetermination regarding the individuality and non-individuality of quantum particles. Section discusses three reactions to it found in the literature: eliminativism about individuality; conservatism about individuality; eliminativism about objects. Section wraps it all up with metametaphysical considerations regarding the epistemology of metaphysics of science.

The aim of this paper is to show that (elementary) topology may be useful for dealing with problems of epistemology and metaphysics. More precisely, I want to show that the introduction of topological structures may elucidate the role of the spatial structures (in a broad sense) that underly logic and cognition. In some detail I’ll deal with “Cassirer’s problem” that may be characterized as an early forrunner of Goodman’s “grue-bleen” problem. On a larger scale, topology turns out to (...) be useful in elaborating the approach of conceptual spaces that in the last twenty years or so has found quite a few applications in cognitive science, psychology, and linguistics. In particular, topology may help distinguish “natural” from “not-so-natural” concepts. This classical problem that up to now has withstood all efforts to solve (or dissolve) it by purely logical methods. Finally, in order to show that a topological perspective may also offer a fresh look on classical metaphysical problems, it is shown that Leibniz’s famous principle of the identity of indiscernibles is closely related to some well-known topological separation axioms. More precisely, the topological perspective gives rise in a natural way to some novel variations of Leibniz’s principle. (shrink)

An overview of the epistemology of perception, covering the nature of justification, immediate justification, the relationship between the metaphysics of perceptual experience and its rational role, the rational role of attention, and cognitive penetrability. The published version will contain a smaller bibliography, due to space constraints in the volume.

Many who take a dismissive attitude towards metaphysics trace their view back to Carnap’s ‘Empiricism, Semantics and Ontology’. But the reason Carnap takes a dismissive attitude to metaphysics is a matter of controversy. I will argue that no reason is given in ‘Empiricism, Semantics and Ontology’, and this is because his reason for rejecting metaphysical debates was given in ‘Pseudo-Problems in Philosophy’. The argument there assumes verificationism, but I will argue that his argument survives the rejection of verificationism. (...) The root of his argument is the claim that metaphysical statements cannot be justified; the point is epistemic, not semantic. I will argue that this remains a powerful challenge to metaphysics that has yet to be adequately answered. (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)

Reductionism about testimony holds that testimonial warrant or entitlement is just a species of inductive warrant. Anti-Reductionism holds that it is different from inductive but analogous to perceptual or memorial warrant. Perception receives much of its positive epistemic status from being reliably truthconducive in normal conditions. One reason to reject the epistemic analogy is that testimony involves agency – it goes through the will of the speaker – but perception does not. A speaker might always choose to lie or otherwise (...) deliberately mislead. It is argued that the force of this derives (in part) from Libertarianism about agency, and that Libertarianism, if it undermines the Anti-Reductionist explanation of why we are entitled to rely upon testimony, undermines the Reductionist explanation as..

It is sometimes argued that, given its detachment from our current most successful science, analytic metaphysics has no epistemic value because it contributes nothing to our knowledge of reality. Relatedly, it is also argued that metaphysics properly constrained by science can avoid that problem. In this paper we argue, however, that given the current understanding of the relation between science and metaphysics, metaphysics allegedly constrained by science suffers the same fate as its unconstrained sister; that is, (...) what is currently thought of as scientifically respectful metaphysics may end up also being without epistemic value. The core of our claim is that although much emphasis is put on the supposed difference between unconstrained analytic metaphysics, in opposition to scientifically constrained metaphysics, it is largely forgotten that no clear constraining relation of metaphysics by science is yet available.

According to a recent proposal, the epistemic aim of metaphysics as a discipline is to chart the different viable theories of metaphysical objects of inquiry (e.g. causation, persistence). This paper elaborates on and seeks to improve on that proposal in two related ways. First, drawing on an analogy with how-possibly explanation in science, I argue that we can usefully understand this aim of metaphysics as the charting of epistemically possible answers to metaphysical questions. Second, I argue that in (...) order to account for the epistemic goodness of this aim, one should appeal to the epistemic value it has in virtue of providing resources for non-factive understanding of the objects of metaphysical inquiry.**This paper is forthcoming in a special issue of Argumenta on the Epistemology of Metaphysics**.

We review some of the major accounts in the current epistemology of modality and identify some shared issues that plague all of them. In order to provide insight into the nature of modal statements in science, philosophy, and beyond, a satisfactory epistemology of modality would need to be suitably applicable to practical and theoretical contexts by limited beings. However, many epistemologies of modality seem to work only when we have access to the kind of knowledge that is at (...) least currently beyond our reach. Or, in the extreme case, it is argued that even if we knew all the relevant information about the respective domain – or even the entire state of the world – there would still remain a special class of modal truths that would be left unaccounted for. Neither picture bodes well for practical applicability, nor for the philosophical justification of these epistemologies. This is especially the case as we hold that one of the main motivations for modal inquiry typically arises in cases of imperfect information and limited cognitive resources. We close by providing a partial remedy to the situation by suggesting an overall framework of relative modality (RM) that can be used to both unify some existing modal epistemologies and, at the same time, make them more metaphysically modest.

This dissertation draws upon historical studies of scientific practice and contemporary issues in the metaphysics and epistemology of science to account for the nature of physical quantities. My dissertation applies this integrated HPS approach to dimensional analysis—a logic for quantitative physical equations which respects the distinct dimensions of quantities (e.g. mass, length, charge). Dimensional analysis and its historical development serve both as subjects of study and as a sources for solutions to contemporary problems. The dissertation consists primarily of (...) three related papers on: (1) the methodological and metaphysical foundations of dimensional analysis, (2) the use of dimensional analysis in determining physical symmetries, (3) the use of dimensional analysis in securing metrological extension.

In this article, I explore the consequences of two commonsensical premises in semantics and epistemology: (1) natural language is a complex system rooted in the communal life of human beings within a given environment; and (2) linguistic knowledge is essentially dependent on natural language. These premises lead me to emphasize the process-socio-environmental character of linguistic meaning and knowledge, from which I proceed to analyse a number of long-standing philosophical problems, attempting to throw new light upon them on these grounds. (...) In particular, I criticize the use of expressions such as ‘absolute truth’, ‘absolute existence’ and ‘the thing in itself’, arguing that they lead to what I call ‘the ultralinguistic paradox’ (a fatal antinomy). In the same way, I review a number of mainstream topics in philosophical semantics, epistemology and metaphysics, reformulating them in terms much more naturalistic – and less mysterious – than usual.

Scholarly debates on the Critique of Pure Reason have largely been shaped by epistemological questions. Challenging this prevailing trend, Kant's Reform of Metaphysics is the first book-length study to interpret Kant's Critique in view of his efforts to turn Christian Wolff's highly influential metaphysics into a science. Karin de Boer situates Kant's pivotal work in the context of eighteenth-century German philosophy, traces the development of Kant's conception of critique, and offers fresh and in-depth analyses of key parts of (...) the Critique of Pure Reason, including the Transcendental Deduction, the Schematism Chapter, the Appendix to the Transcendental Analytic, and the Architectonic. The book not only brings out the coherence of Kant's project, but also reconstructs the outline of the 'system of pure reason' for which the Critique was to pave the way, but that never saw the light.

Kant's account of space as an infinite given magnitude in the Critique of Pure Reason is paradoxical, since infinite magnitudes go beyond the limits of possible experience. Michael Friedman's and Charles Parsons's accounts make sense of geometrical construction, but I argue that they do not resolve the paradox. I argue that metaphysical space is based on the ability of the subject to generate distinctly oriented spatial magnitudes of invariant scalar quantity through translation or rotation. The set of determinately oriented, constructed (...) geometrical spaces is a proper subset of metaphysical space, thus, metaphysical space is infinite. Kant's paradoxical doctrine of metaphysical space is necessary to reconcile his empiricism with his transcendental idealism. (shrink)

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 theory of mind that medieval philosophers inherit from Augustine is predicated on the thesis that the human mind is essentially self-reflexive. This paper examines Peter John Olivi's (1248-1298) distinctive development of this traditional Augustinian thesis. The aim of the paper is three-fold. The first is to establish that Olivi's theory of reflexive awareness amounts to a theory of phenomenal consciousness. The second is to show that, despite appearances, Olivi rejects a higher-order analysis of consciousness in favor of a same-order (...) theory. The third and final is to show that, on his view, consciousness is both self-intimating and infallible. (shrink)

Friedrich Nietzsche’s contribution to philosophy is mostly recognized in relation to moral philosophy. His distinction of master and slave morality, critique of the Judeo-Christian morality is what is commonly considered as the main contribution of his philosophy. How-ever, on the other hand, his examination of metaphysics and epistemology comprises fun-damental constituents to apprehend his philosophy. Accordingly, it can be said, Nietzsche’s approach towards morality and politics is a demonstration of his analysis of metaphysics and epistemology. Since (...) the construction of metaphysical and epistemological grounds precedes the construction of ethical systems, the critique of morality is presupposed by the critique of its metaphysical and epistemological foundations. Therefore, the focus of this paper will not be Nietzsche’s critique of morality and politics. Rather, it will critically examine his criticism of the metaphysical and epistemological ba-sis that by virtue of their structural fundamentality acquired the generative potential of values (moral, political, economic, etc.). In view of that, by exposing the vitality of Nie-tzsche’s critique in his discourse on nihilism, the analysis will try to claim the conceptual centrality of nihilism in his philosophy. Furthermore, assert the possible understandability of his critique and discourse, which is mostly concentrated on the advent of European ni-hilism and its countermovement. (shrink)

This précis provides a chapter-by-chapter summary of Metaphysics of States of Affairs (Springer, 2018).

Standard objections to the notion of a hedged, or ceteris paribus, law of nature usually boil down to the claim that such laws would be either 1) irredeemably vague, 2) untestable, 3) vacuous, 4) false, or a combination thereof. Using epidemiological studies in nutrition science as an example, I show that this is not true of the hedged law-like generalizations derived from data models used to interpret large and varied sets of empirical observations. Although it may be ‘in principle impossible’ (...) to construct models that explicitly identify all potential causal interferers with the relevant generalization, the view that our failure to do so is fatal to the very notion of a cp-law is plausible only if one illicitly infers metaphysical impossibility from epistemic impossibility. I close with the suggestion that a model-theoretic approach to cp-laws poses a problem for recent attempts to formulate a Mill-Ramsey-Lewis theory of cp-laws. (shrink)

While recent history has seen significant debate concerning the nature and extension of essence, comparatively little attention has been paid to the epistemology of essence. This is strange, as, plausibly, what answers we give to the metaphysical questions about essence will (or should) be partially constrained by our essence epistemology. Here, I aim to go some way towards filling this lacuna. In particular, I here argue that there is no plausible epistemic story available for non-modal accounts of essence. (...) In particular, existing accounts of essence epistemology cannot explain how we are able to know that something is genuinely essential, rather than merely necessary. One consequence is that modal accounts of essence – which only needs to supply an epistemology for a non-hyperintensional notion – look that much more plausible. (shrink)

The paper explores the project of an ambitious modal epistemology that attempts to combine the a priori methods of Chalmers’ 2D semantics with Kripke’s modal metaphysics. I argue that such a project is not viable. The ambitious modal epistemology involves an inconsistent triad composed of (1) Modal Monism, (2) Two-Dimensionalism, and what I call (3) “Metaphysical Kripkeanism”. I present the three theses and show how only two of those can be true at a time. There is a (...) fundamental incompatibility between Chalmers’ Modal Rationalism and Kripke’s modal metaphysics. Specifically, Chalmers’ conceivability entails possibilities that a Kripkean rejects as genuinely metaphysical. However, three positive stances in modal epistemology emerge from the combinations that the triad allows. One of those offers a promising way forward for 2D modal epistemologies. But it comes with a cost, as it requires abandoning modal monism and reshaping the scope of what a priori conceivability can give us access to. (shrink)

In this paper, I discuss the main characteristics of the epistemology of modal rationalism by proceeding from the critical investigation of Peacocke’s theory of modality. I build on arguments by Crispin Wright and Sonia Roca-Royes, which are generalised and supplemented by further analysis, in order to show that principle-based accounts have little prospects of succeeding in their task of providing an integrated account of the metaphysics and the epistemology of modality. I argue that it is unlikely that (...) we will able to develop an exhaustive and accurate principle-based account that discriminates objectively between correct and deviant modal knowledge. Even if such an account can be formulated, a non-circular way of justifying its necessity also seems to be out of our reach. (shrink)

Erik Wielenberg’s new book Robust Ethics: The Metaphysics and Epistemology of Godless Normative Realism aims at defending a non-theistic of ‘robust normative realism’: the metaethical view that normative properties exist, and have four features: (1) objectivity, (2) non-naturalness, (3) irreducibility, and (4) causal inertness. In my review I criticize that Wielenberg does not address semantic issues which are crucial both to defending robust normative realism, and to assessing the empirical claims he makes. Moreover, and relatedly, I suggest that (...) Wielenberg’s main psychological and evolutionary claims may be less well-founded than suggested. Despite these worries, however, Robust Ethics is a highly valuable contribution to metaethics. Wielenberg’s writing is extremely accessible, engaging, witty, and clear, he develops various fascinating novel arguments, and skilfully links analytic reflections with the consideration of empirical data.

I will explore the paradoxical nature of epistemic access. By critiquing the traditional conception of mental states that are labelled as ’knowledge’, I demonstrate the susceptibility of these states to an infinite regress, thus, challenging their existence and validity. I scrutinise the assumption that an epistemic agent can have complete epistemic access to all facts about a given object while simultaneously being ignorant of certain truths that impact the very knowledge claims about the object. I further analyse the implications of (...) this paradox when attempting to fine-grain the parameters of epistemic access, which happens to reveal the vacuity of such definitions and the inevitability of the regress. (shrink)

The starting point of this paper is an argument to the conclusion that the definition of metaphysical possibility in terms of correct conceivability, conceivability informed by knowledge of relevant essences, found in Rosen (2006) is equivalent to a version of the essentialist definition of metaphysical necessity. This argument appears to show that correct conceivability is a notion of conceivability by name only and is therefore of no interest to epistemologists of modality. In this paper, I present the equivalence argument, explain (...) the idealizing assumptions involved in it and sketch a version of the conceivability approach which weakens these assumptions in order to show that the notion of correct conceivability can still play a specific limited role in the epistemology of modality.

Hume establishes a link between our capacity to conceive or form “clear and distinct ideas” and metaphysical possibility. Hume’s so-called Conceivability Principle is usually assumed to be epistemic: conceivability is supposed to inform us of independent metaphysical facts. In this chapter, however, I argue that Hume is not engaged in modal epistemology. For Hume, there is no epistemic relation between conceivability and an independent metaphysical world of possibilities. On my reading, conceivability is more like the “mètre étalon” in Paris—the (...) standard unit of measurement of length—than a window or telescope into some metaphysical world. Conceivability is the standard of metaphysical possibility. And just as the meter is defined as a certain distance of light traveled, for Hume, conceivability is defined in terms of the liberty of the imagination. I discuss how Hume deploys conceivability along with knowledge—the standard of metaphysical necessity—as tools for measuring or assessing the alleged metaphysical necessity of a cause to every beginning of existence and the alleged rational foundation of causal inferences.

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.

Dispositionalism is the theory of modality that grounds all modal truths in powers: all metaphysically possible and necessary truths are to be explained by pointing to some actual power, or absence thereof. One of the main reasons to endorse dispositionalism is that it promises to deliver an especially desirable epistemology of modality. However, so far this issue has not be fully investigated with the care it is due. The aim of this paper is to fill this gap. We will (...) cast some doubts on whether the dispositionalist really is in a better position to explain our modal knowledge. In fact, we argue that there is a tension between some core tenets of a powers metaphysics and the very features that make dispositionalism the ideal backdrop for a desirable epistemology of modality. We conclude that this leaves dispositionalists who want to deliver the promised epistemology with a hard, currently unfulfilled, task. (shrink)

This paper delves into the examination of metaphysical knowledge from the unique vantage point of Thomas Reid. While some philosophers, including Immanuel Kant, assert the impossibility of metaphysical knowledge based on specific epistemological and methodological principles, Reid, a proponent of direct realism, presents alternative epistemological and methodological principles that challenge the skeptics’ stance. The primary objective of this paper is to explore whether metaphysical knowledge is attainable through Reid’s perspective. In this paper, I contend that Reid’s direct realism indeed opens (...) up the possibility of metaphysics. Nevertheless, determining whether we truly possess metaphysical knowledge is far from straightforward. Instead, we rely on reliable tests to evaluate the reliability of some metaphysical beliefs.

The concept of time-travel is a modern idea which combines the imaginary signification of rational domination, the imaginary signification of technological omnipotence, the imaginary concept of eternity and the imaginary desire for immortality. It is a synthesis of central conceptual schemata of techno-science, such as the linearity and homogeneity of time, the radical separation of subjectivity from the world, the radical separation of the individual from his/her social-historical environment. The emergence of this idea, its spread during the 20th century as (...) a major theme of science fiction literature alongside its dissemination as a scientific hypothesis, its popularity with both the public and the scientific community, are indications of the religious role of techno-science. It is my opinion, finally, that, as a chimera, time-travel is non-feasible and impossible. In order to support my claims, I will briefly outline the origins of the time-travel concept and its epistemological and metaphysical/ontological conditions. If these conditions prove to be absurd, the logical impossibility of time-travel will have been demonstrated. (shrink)

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.

I outline Hume’s views about conceivability evidence. Then I critically scrutinize two threats to conceivability-based modal epistemology. Both arise from Hume’s criticism of claims to knowing necessary causal relationships: Firstly, a sceptical stance towards causal necessity may carry over to necessity claims in general. Secondly, since – according to a sceptical realist reading – Hume grants the eventuality of causal powers grounded in essential features of objects, conceivability-based claims to comprehensive metaphysical possibilities seem endangered. I argue that although normal (...) conceivability-based claims are defeasible, they are prima facie vindicated. (shrink)

Current health care standards, in many countries, Australia included, are regrettably poor. Surprisingly, practitioners and treating teams alike in mental health and disability sectors, in particular, make far too many basic care-related mistakes, in addition to the already abundant diagnostic mistakes that cause and amplify great harm. In part, too many practitioners also fail to distinguish adverse effects for what they are and all too often treat adverse effects, instead, as comorbidities. Diagnostic failures are dangerous, the result of which generates (...) and perpetuates harms that are extremely costly in terms of patient welfare, in addition to the financial burden placed on everyone. In this essay, I contend that the authority bestowed upon psychiatry is misplaced. Subsequently, this misplaced authority affects the governing and investigatory institutions reliant and informed by psychiatry. The examination process undertaken in this investigation traces the metaphysics of psychiatric disorders relative to the Diagnostic-Statistical-Manual (DSM) in all its iterations and to the epistemological construction process that serves to underpin the fundamentals of psychiatric practice. There exists a crisis of confidence in psychiatric practice and I urge drastic reform be undertaken to arrest the damage. (shrink)

Recent epistemology of modality has seen a growing trend towards metaphysics-first approaches. Contrastingly, this paper offers a more philosophically modest account of justifying modal claims, focusing on the practices of scientific modal inferences. Two ways of making such inferences are identified and analyzed: actualist-manipulationist modality and relative modality. In AM, what is observed to be or not to be the case in actuality or under manipulations, allows us to make modal inferences. AM-based inferences are fallible, but the same (...) holds for practically all empirical inquiry. In RM, modal inferences are evaluated relative to what is kept fixed in a system, like a theory or a model. RM-based inferences are more certain but framework-dependent. While elements from both AM and RM can be found in some existing accounts of modality, it is worth highlighting them in their own right and isolating their features for closer scrutiny. This helps to establish their relevant epistemologies that are free from some strong philosophical assumptions often attached to them in the literature. We close by showing how combining these two routes amounts to a view that accounts for a rich variety of modal inferences in science. (shrink)

This study deals with Dominicus Gundissalinus’s discussion on metaphysics as philosophical discipline. Gundissalinus’s translation and re-elaboration of al-Fārābī’s Iḥṣā’ al-ʿulūm furnish him, in the De scientiis, a specific and detailed procedure for metaphysical analysis articulated in two different stages, an ascending and a descending one. This very same procedure is presented by Gundissalinus also in his De divisione philosophiae, where the increased number of sources –in particular, Avicenna– does not prevent Gundissalinus to quote the entire passage on the methods (...) of metaphysical science from the Iḥṣā’ al-ʿulūm, with some slight changes in his Latin translation. The analytical procedure herein proposed becomes an effective ‘metaphysical programme’ with regards to Gundissalinus’s onto-cosmological writing, the De processione mundi. The comparative analysis of this treatise with the procedure received by al-Fārābī shows Gundissalinus’s effort to follow and apply this metaphysical programme to his own reflection, in a whole different context from al-Fārābī’s and presenting doctrines quite opposed to the theoretical ground on which al-Fārābī’s epistemology is based, like ibn Gabirol’s universal hylomorphism. Nevertheless, thanks to the application of the ‘metaphysical programme’, one can effectively claim that Gundissalinus’s metaphysics is, at least in the author’s intentions, a well-defined metaphysical system. In appendix to this article the three Latin versions of al-Fārābī’s discussion on metaphysics are reported, e.g., Gundissalinus’s quotations in De scientiis and De divisione philosophiae, and Gerard of Cremona’s translation in his De scientiis.

True contradictions are taken increasingly seriously by philosophers and logicians. Yet, the belief that contradictions are always false remains deeply intuitive. This paper confronts this belief head-on by explaining in detail how one specific contradiction is true. The contradiction in question derives from Priest's reworking of Berkeley's argument for idealism. However, technical aspects of the explanation offered here differ considerably from Priest's derivation. The explanation uses novel formal and epistemological tools to guide the reader through a valid argument with, not (...) just true, but eminently acceptable premises, to an admittedly unusual conclusion: a true contradiction. The novel formal and epistemological tools concern points of view and changes in points of view. The result is an understanding of why the contradiction is true. (shrink)

Ordinary language and scientific discourse are filled with linguistic expressions for dispositional properties such as “soluble,” “elastic,” “reliable,” and “humorous.” We characterize objects in all domains – physical objects as well as human persons – with the help of dispositional expressions. Hence, the concept of a disposition has historically and systematically played a central role in different areas of philosophy ranging from metaphysics to ethics. The contributions of this volume analyze the ancient foundations of the discussion about disposition, examine (...) the problem of disposition within the context of the foundation of modern science, and analyze this dispute up to the 20th century. Furthermore, articles explore the contemporary theories of dispositions. (shrink)

This paper aims to better motivate the naturalization of metaphysics by identifying and criticizing a class of theories I call ’free range metaphysics’. I argue that free range metaphysics is epistemically inadequate because the constraints on its content—consistency, simplicity, intuitive plausibility, and explanatory power—are insufficiently robust and justificatory. However, since free range metaphysics yields clarity-conducive techniques, incubates science, and produces conceptual and formal tools useful for scientifically engaged philosophy, I do not recommend its discontinuation. I do (...) recommend, however, ending the discipline’s bad faith. That is, I urge that free range metaphysics not be taken to have fully satisfactory epistemic credentials over and above its pragmatic ones. (shrink)

Critique of Sarcastic Reason is a philosophical dissertation that combines several different fields in order to pave the way for those studying sarcasm at the neurobiological, communicative and socio-political levels of analysis where sarcasm appears, respectively, through associated brain activity, between two or more individuals with higher level metabeliefs, and as a method by which political, religious and other social ideologies are attacked (i.e., one form of "biting sarcasm"). The academic disciplines involved in Critique of Sarcastic Reason include social cognitive (...) and developmental psychology, neuroscience, critical theory, modern and contemporary philosophy of mind, evolutionary biology, logic, metaphysics and epistemology. Sarcasm is argued to only function at the highest levels of metacognition, and sarcasm occurs within social situations during which there are tendencies for two or more people to form desires and disgusts directly related to beliefs about beliefs. Sarcasm is compared to deception and is argued to be best analyzed as either spontaneous or rehearsed. (shrink)

Commentators regularly attribute to Frege realist, idealist, and quietist responses to metaphysical questions concerning the abstract objects he calls ‘thoughts’. But despite decades of effort, the evidence offered on behalf of these attributions remains unconvincing. I argue that Frege deliberately avoids commitment to any of these positions, as part of a metaphysical separatist policy motivated by the fact that logic is epistemologically autonomous from metaphysics. Frege’s views and arguments prove relevant to current attempts to argue for epistemological autonomy, particularly (...) that of ethics. (shrink)

Although metaphysics has made an impressive comeback over the past half century, there are still a great many philosophers today who think it is bullshit, under numerous precisifications of ‘That’s just bullshit’ so that it’s a negative assessment and doesn’t apply to most philosophy. One encounters this attitude countless times in casual conversations, social media, and occasionally in print. Is it true?

The aim of this study is to examine the relation between Nietzsche’s perspectivism and his doctrine of the will to power and to show that perspectivism is almost a direct and natural consequence of the doctrine of the will to power. Without exploring the doctrine, it is not possible to understand what Nietzsche’s perspectivism is and what he trying to do by proposing it as an alternative to traditional epistemology. To this aim, firstly, Nietzsche’s doctrine of the will to (...) power is explained in detail. Next, in order to provide a deeper understanding of the doctrine, its relation with Darwinism and the claims which say that it is a metaphysical principle are analyzed. Afterwards, Nietzsche’s construction of the world as becoming out of will to power is investigated. Nietzsche’s conception of interpretation as power struggle and its role in perspectivism explained. Then, how Nietzsche’s construction of the world as becoming and his concept of interpretation as power struggle emerge as perspectivism is explained. After that, in order to present the differences between Nietzsche’s perspectivism and traditional understanding of epistemology, Nietzsche’s critiques of some of the fundamental assumptions of traditional epistemology, i.e., causality, logic, and subject-object and apparent-real world distinctions, are investigated. Finally, Nietzsche’s understanding of truth based on his perspectivism is inquired. Its relation with correspondence, pragmatic and coherence theories of truth is explored to show that Nietzsche’s understanding of truth could not be comprehended through these theories. Consequently, it isclaimed that the tendency to attribute a truth theory to Nietzsche’s perspectivism, which is prevalent in the current Nietzsche studies, stems from commentator’s, consciously or unconsciously, ignoring of the relation between his perspectivism and his doctrine of the will to power.

The integration challenge for modality states that metaphysical theories of modality tend to fail in one of two ways: either they render the meanings of modal sentences mysterious, or they render modal knowledge mysterious. I argue that there are specific semantic and epistemic constraints on metaphysics implied by the integration challenge and that a plausible metaphysical theory of modality will satisfy both of them. I further argue that no popular metaphysical theory of modality simultaneously satisfies both of the constraints. (...) Therefore, a new metaphysical theory of modality is needed, one that can offer a clear response to the integration challenge. I attempt to supply the needed theory and show that it satisfies the constraints of the integration challenge. The overall result is an argument for a new and unique metaphysical theory of modality that I call constructionism. (shrink)

Locke’s theory of personal identity was philosophically groundbreaking for its attempt to establish a non-substantial identity condition. Locke states, “For the same consciousness being preserv’d, whether in the same or different Substances, the personal Identity is preserv’d” (II.xxvii.13). Many have interpreted Locke to think that consciousness identifies a self both synchronically and diachronically by attributing thoughts and actions to a self. Thus, many have attributed to Locke either a memory theory or an appropriation theory of personal identity. But the former (...) stumble on circularity and the latter is insufficient for Locke’s moral theory insofar as he is committed to a theory of divine rectification. The common problem is that Locke’s theory seems to demand an objective, or metaphysical, fact of a continuing consciousness that does not appeal to a traditional notion of substance for the continuity. I’m suggesting something new. In II.xxvii of the Essay, we see an ambiguity in Locke’s use of the term ‘consciousness’. Locke seems to see consciousness as both a mental state by means of which we are aware of ourselves as perceiving and as the ongoing self we are aware of in these conscious states. First, I make the textual argument why we should read Locke as having a conception of a metaphysical fact of a continuing consciousness that does not appeal to thinking or bodily substance to establish its continuity. I then argue that the metaphysical fact of an enduring consciousness is revealed to us as a phenomenological fact of experience. Due to the nature of certain kinds of perceptual situations we have an experience of ourselves as temporally extended. Although the text bears out that Locke seemed to think there is a fact of an ongoing consciousness, I argue that it is consistent with his reluctance elsewhere that he makes no further epistemological or ontological claims about it. Finally, I provide an account of Locke’s understanding of memory and its relation to consciousness that supports the claim that consciousness is something ontologically distinct from either thinking or bodily substance.

How can an event be extraordinary? What is the metaphysical background necessary to believe that extraordinary events are possible? The possibility of extraordinary events can be approached from metaphysical, epistemic, and scientific perspectives. Metaphysical explanations are extraordinary events that transcend nature or violate the regular structure in nature. Epistemological explanations, on the other hand, are explanations of extraordinary events by referring either to our lack of knowledge about nature or to our inadequacy of knowledge about events. Scientific explanations recognize phenomena (...) that have been observed or experimented on but have not yet been explained by any theory. In this article, I focus on metaphysical and epistemological explanations. We see that three basic assumptions are used for a metaphysical explanation: 1) There must be an orderly operation called Nature. 2) The process in nature can be violated. 3) There is a compatibility between the mind and the world. With the adoption of these three assumptions by different philosophers in various combinations, two kinds of metaphysical explanations arise: extraordinary as supernatural and extraordinary by appealing to the principle of sufficient reason. According to the first type of explanation, extraordinary events are events caused by what is beyond nature, exceeding nature, or violating the workings of nature. In order to explain extraordinary events with the supernatural, there is a need to violate the metaphysical necessities on which nature is based, such as the principle of causality. An approach represented by philosophers such as St. Augustine, al-Ghazālī, Richard Swinburne, and Nazif Muhtaroğlu claims that it is possible for a supernatural event to occur, claiming that the functioning of nature is not necessary. But if there is no metaphysical necessity in nature such as the principle of causality, how can an extraordinary event violate anything? Both Swinburne and St. Augustine answer this question with the argument that the principle of causality is effective in nature and that principle can be violated by God, a supernatural power. Al-Ghazālī and Muhtaroğlu, on the other hand, prefer not to accept the effectiveness of causality in the functioning of nature. Thus, all activity in nature will be attributed to God, and extraordinary events will gain the same status as ordinary events. The point that unites these views is the belief that the operation in nature is not necessary, with or without causality. Philosophers with this belief could not successfully explain extraordinary events because they could not ground their understanding of nature and the supernatural. Moreover, when we analyze their approach to the problem, we see that ordinary and extraordinary events cannot be separated from each other, since no other principle is put forward to replace the principle of causality. The second type of explanation is the explanation of extraordinary events by applying the principle of sufficient reason. The philosophers represented by Ibn Sînâ and Leibniz consider it necessary both metaphysically and epistemologically that everything in nature needs sufficient reason to come to be. According to them, no event can take place without sufficient cause. In this respect, there must be sufficient reason for extraordinary events to occur as well as ordinary ones. Both philosophers argue that extraordinary events are metaphysically possible events in nature, but their occurance does not violate principles such as causality. According to this type of explanation, extraordinary events are not supernatural. Ibn Sînâ, using the concept of nature in its metaphysical sense, argued that forces beyond matter are also effective in nature. Meanwhile, he maintained the necessity of the causality principle. In this way, it is possible to have previously unknown results from known causes. For example, the human soul can affect different bodies through celestial realms, just as it affects its own body. However, this interaction does not violate the necessity of the causality principle, on the contrary, it means the discovery of the necessary structure of nature. In short, the epistemological approaches of Leibniz and Ibn Sînâ, which they developed while preserving the metaphysical necessity of causation, do not require denying extraordinary events without examining them, but also offer a stronger basis for the possibility of extraordinary events, as they expand the limits of our knowledge of nature.

Despite their divergent metaphysical assumptions, Reformed and evolutionary epistemologists have converged on the notion of proper basicality. Where Reformed epistemologists appeal to God, who has designed the mind in such a way that it successfully aims at the truth, evolutionary epistemologists appeal to natural selection as a mechanism that favors truth-preserving cognitive capacities. This paper investigates whether Reformed and evolutionary epistemological accounts of theistic belief are compatible. We will argue that their chief incompatibility lies in the noetic effects of sin (...) and what may be termed the noetic effects of evolution, systematic tendencies wherein human cognitive faculties go awry. We propose a reconceptualization of the noetic effects of sin to mitigate this tension. (shrink)

The epistemology of modality has focused on metaphysical modality and, more recently, counterfactual conditionals. Knowledge of kinds of modality that are not metaphysical has so far gone largely unexplored. Yet other theoretically interesting kinds of modality, such as nomic, practical, and ‘easy’ possibility, are no less puzzling epistemologically. Could Clinton easily have won the 2016 presidential election—was it an easy possibility? Given that she didn’t in fact win the election, how, if at all, can we know whether she easily (...) could have? This paper investigates the epistemology of the broad category of ‘objective’ modality, of which metaphysical modality is a special, limiting case. It argues that the same cognitive mechanisms that are capable of producing knowledge of metaphysical modality are also capable of producing knowledge of all other objective modalities. This conclusion can be used to explain the roles of counterfactual reasoning and the imagination in the epistemology of objective modality. (shrink)

The Millian semantic view of names relies on a metaphysical view of names—often given the label ‘common currency conception’ —on which the names of distinct individuals count as distinct names. While even defenders of the Millian view admit that the CCC ‘does not agree with the most common usage’, I will argue further that the CCC makes names exceptional amongst the class of linguistic expressions: if the CCC is correct, then names must have a sui-generis metaphysical nature, distinct from the (...) metaphysics of every other kind of linguistic expression. Such metaphysical exceptionalism would be justified if the Millian view had a clear, uncontested theoretical advantage over its rivals. However, in the context of a semantic debate about names in which the closest competitors of the Millian view—the Predicate view and Indexicalism—do not result in such exceptionalism, it counts as a strike against the Millian view.

Remhof contends that Nietzsche is a metaphysician. According to his Meta-Metaphysical Argument, Nietzsche’s texts satisfy the criteria for an adequate conception of metaphysics. According to his Constructivist Argument, Nietzsche adopts a metaphysical position on which concepts’ application conditions constitute the identity conditions of their objects. This article critically appraises these arguments. I maintain that the criteria advanced in the Meta-Metaphysical Argument are collectively insufficient for delineating metaphysics as a distinct field of inquiry and that the Constructivist Argument attributes (...) a position to Nietzsche that remains vulnerable to his evaluative and psychological indictments of two-world metaphysics. I conclude by discussing how these objections might help non-metaphysical readers of Nietzsche resist Remhof’s interpretation. (shrink)
