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.

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)

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)

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..

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)

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)

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)

In this paper, I present a new reading of transcendental idealism. For a start, I endorse Allison’s rejection of the traditional so-called two-world view and, hence, of Guyer and Van Cleve’s ontological phenomenalism. But following Allais, I also reject Allison’s metaphysical deflacionism: transcendental idealism is metaphysically committed to the existence of things in themselves, noumena in the negative sense. Nevertheless, in opposition to Allais, I take Kant’s claim that appearances are “mere representations” inside our minds seriously. In the empirical sense, (...) appearances are the undetermined object of our sensible intuition. Yet, in the transcendental sense, appearances are nothing but the mind-dependent way that noumena manifest inside our minds and, hence, our mind-dependent way of knowing the mind-independent reality in itself (epistemological phenomenalism).

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)

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; 2020) 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 hoc distinction 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 asserted must attend the agent’s imperfect epistemic access thereof, therefore entailing claims of modality consistent with her epistemic state – i.e., 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.

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.

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.

This paper develops and motivates a unification theory of metaphysical explanation, or as I will call it, Metaphysical Unificationism. The theory’s main inspiration is the unification account of scientific explanation, according to which explanatoriness is a holistic feature of theories that derive a large number of explananda from a meager set of explanantia, using a small number of argument patterns. In developing Metaphysical Unificationism, I will point out that it has a number of interesting consequences. The view offers a novel (...) conception of metaphysical explanation that doesn’t rely on the notion of a “determinative” or “explanatory” relation; it allows us to draw a principled distinction between metaphysical and scientific explanations; it implies that naturalness and fundamentality are distinct but intimately related notions; and perhaps most importantly, it re-establishes the unduly neglected link between explanation and understanding in the metaphysical realm. A number of objections can be raised against the view, but I will argue that none of these is conclusive. The upshot is that Metaphysical Unificationism provides a powerful and hitherto overlooked alternative to extant theories of metaphysical explanation. (shrink)

The paper begins with a clarification of the notions of intuition (and, in particular, modal intuition), modal error, conceivability, metaphysical possibility, and epistemic possibility. It is argued that two-dimensionalism is the wrong framework for modal epistemology and that a certain nonreductionist approach to the theory of concepts and propositions is required instead. Finally, there is an examination of moderate rationalism’s impact on modal arguments in the philosophy of mind -- for example, Yablo’s disembodiment argument and Chalmers’s zombie argument. A (...) less vulnerable style of modal argument is defended, which nevertheless wins the same anti-materialist conclusions sought by these other arguments. (shrink)

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)

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.

It is now common to distinguish Metaphysical from Epistemological Disjunctivism. It is equally common to suggest that it is at least not obvious that the latter requires a commitment to the former: at the very least, a suitable bridge principle will need to be identified which takes one from the latter to the former. This paper identifies a plausible-looking bridge principle that takes one from the version of Epistemological Disjunctivism defended by John McDowell and Duncan Pritchard, which I label Reflective (...) Epistemological Disjunctivism, or (RED), to Metaphysical Disjunctivism. Moreover, it identifies a modification the proponent of (RED) could, and should, make to the Internalist component of their theory, and argues that the commitment to Metaphysical Disjunctivism remains, even if such a modification is made. The upshot is that the commitment to Metaphysical Disjunctivism on the part of (RED) is shown to be particularly robust. (shrink)

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)

I examine the epistemological debate on scientific realism in the context of quantum physics, focusing on the empirical underdetermin- ation of different formulations and interpretations of QM. I will argue that much of the interpretational, metaphysical work on QM tran- scends the kinds of realist commitments that are well-motivated in the light of the history of science. I sketch a way of demarcating empirically well-confirmed aspects of QM from speculative quantum metaphysics in a way that coheres with anti-realist evidence (...) from the history of science. The minimal realist attitude sketched withholds realist com- mitment to what quantum state |Ψ⟩ represents. I argue that such commitment is not required for fulfilling the ultimate realist motiva- tion: accounting for the empirical success of quantum mechanics in a way that is in tune with a broader understanding of how theoretical science progresses and latches onto reality.

It is widely alleged that metaphysical possibility is “absolute” possibility Conceivability and possibility, Clarendon, Oxford, 2002, p 16; Stalnaker, in: Stalnaker Ways a world might be: metaphysical and anti-metaphysical essays, Oxford University Press, Oxford, 2003, pp 201–215; Williamson in Can J Philos 46:453–492, 2016). Kripke calls metaphysical necessity “necessity in the highest degree”. Van Inwagen claims that if P is metaphysically possible, then it is possible “tout court. Possible simpliciter. Possible period…. possib without qualification.” And Stalnaker writes, “we can agree (...) with Frank Jackson, David Chalmers, Saul Kripke, David Lewis, and most others who allow themselves to talk about possible worlds at all, that metaphysical necessity is necessity in the widest sense.” What exactly does the thesis that metaphysical possibility is absolute amount to? Is it true? In this article, I argue that, assuming that the thesis is not merely terminological, and lacking in any metaphysical interest, it is an article of faith. I conclude with the suggestion that metaphysical possibility may lack the metaphysical significance that is widely attributed to it. (shrink)

A naturalistic impulse has taken speculative analytic metaphysics in its critical sights. Importantly, the claim that it is desirable or requisite to give metaphysics scientific moorings rests on underlying epistemological assumptions or principles. If the naturalistic impulse toward metaphysics is to be well-founded and its prescriptions to have normative force, those assumptions or principles should be spelled out and justified. In short, advocates of naturalized or scientific metaphysics require epistemic infrastructure. This paper begins to supply it. (...) The author first sketches her conception of suitably naturalized or scientific metaphysics. She then lays out a number of candidate epistemic principles centring around the notion of theoretical constraint. The author offers several arguments for the principles, based on statistical likeliness, agreement, falsity avoidance, and methodological efficiency and inefficiency. Finally, she shows how scientific metaphysics satisfies the epistemic principles and is therefore preferable to its traditional rivals. (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)

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.

The paper argues against Peacocke's moderate rationalism in modality. In the first part, I show, by identifying an argumentative gap in its epistemology, that Peacocke's account has not met the Integration Challenge. I then argue that we should modify the account's metaphysics of modal concepts in order to avoid implausible consequences with regards to their possession conditions. This modification generates no extra explanatory gap. Yet, once the minimal modification that avoids those implausible consequences is made, the resulting account (...) cannot support Peacocke's moderate rationalism. (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)

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)

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.

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.

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.

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.

Metaphysics is supposed to tell us about the metaphysical nature of our world: under what conditions composition occurs; how objects persist through time; whether properties are universals or tropes. It is near orthodoxy that whichever of these sorts of metaphysical claims is true is necessarily true. This paper looks at the debate between that orthodox view and a recently emerging view that claims like these are contingent, by focusing on the metaphysical debate between monists and pluralists about concrete particulars. (...) This paper argues that we should be contingentists about monism and pluralism, and it defends contingentism against some necessitarian objections by offering an epistemology of contingent metaphysical claims.

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.

John Perry has argued that language, thought and experience often contain unarticulated constituents. I argue that this idea holds the key to explaining away the intuitive appeal of the A-theory of time and the endurance theory of persistence. The A-theory has seemed intuitively appealing because the nature of temporal experience makes it natural for us to use one-place predicates like past to deal with what are really two-place relations, one of whose constituents is unarticulated. The endurance view can be treated (...) in a similar way; the temporal boundaries of temporal parts of objects are unarticulated in experience and this makes it seem that the very same entity exists at different times.

People see five kinds of views in epistemology and ontology as hinging on there being words a person can learn only by private ostensive definitions, through direct acquaintance with his own sensations: skepticism about other minds, 2. skepticism about an external world, 3. foundationalism, 4. dualism, and 5. phenomenalism. People think Wittgenstein refuted these views by showing, they believe, no word is learnable only by private ostensive definition. I defend these five views from Wittgenstein’s attack.

I propose that metaphysical study is initially indifferent to the truth of Metaphysical Realism about Metaphysics (MRM) and Metaphysical Realism and does not presuppose them. Metaphysical Realism is a metaphysical doctrine the truth of which cannot be settled logically prior to metaphysical investigation. MRM presupposes Metaphysical Realism and therefore, one should not hold MRM uncritically. An epistemological consequence of this is that arguments against the possibility of cognition about metaphysically real entities (by e.g., Hume) are not arguments against the (...) epistemic legitimacy of metaphysics without further arguments for MRM. This paper is also a case study of the philosophical significance of having rich enough acquaintance with the history of philosophy, the recent history included. (shrink)

Scholars of African moral thought reject the possibility of an African religious ethics by invoking at least three major reasons. The first objection to ‘ethical supernaturalism’ argues that it is part of those aspects of African culture that are ‘anachronistic’ insofar as they are superstitious rather than rational; as such, they should be jettisoned. The second objection points out that ethical supernaturalism is incompatible with the utilitarian approach to religion that typically characterises some African peoples’ orientation to it. The last (...) objection argues that religious ethics by their very nature require the feature (of revelation), which is generally lacking in African religious experiences. The facet of revelation is crucial for a religious ethics since it solves the epistemological problem of knowing the will of God or the content of morality. In this article, I construct a vitality-based African religious moral theory; and, I argue that it can successfully meet these objections. (shrink)

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)

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?

Augmented reality (AR) technologies function to ‘augment’ normal perception by superimposing virtual objects onto an agent’s visual field. The philosophy of augmented reality is a small but growing subfield within the philosophy of technology. Existing work in this subfield includes research on the phenomenology of augmented experiences, the metaphysics of virtual objects, and different ethical issues associated with AR systems, including (but not limited to) issues of privacy, property rights, ownership, trust, and informed consent. This paper addresses some epistemological (...) issues posed by AR systems. I focus on a near-future version of AR technology called the Real-World Web, which promises to radically transform the nature of our relationship to digital information by mixing the virtual with the physical. I argue that the Real-World Web (RWW) threatens to exacerbate three existing epistemic problems in the digital age: the problem of digital distraction, the problem of digital deception, and the problem of digital divergence. The RWW is poised to present new versions of these problems in the form of what I call the augmented attention economy, augmented skepticism, and the problem of other augmented minds. The paper draws on a range of empirical research on AR and offers a phenomenological analysis of virtual objects as perceptual affordances to help ground and guide the speculative nature of the discussion. It also considers a few policy-based and designed-based proposals to mitigate the epistemic threats posed by AR technology. (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)

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. -/- .

This paper pulls together three debates fundamental in metaphysics and proposes a novel unified approach to them. The three debates are (i) between bundle theory and substrate theory about the nature of objects, (ii) dispositionalism and categoricalism about the nature of properties, and (iii) regularity theory and production theory about the nature of causation. The first part of the paper (§§2-4) suggests that although these debates are metaphysical, the considerations motivating the competing approaches in each debate tend to be (...) epistemological. The second part (§§5-6) argues that the two underlying epistemological pictures supporting competing views lead to highly unsatisfying conceptions of the world. The final part (§§7-10) proposes an alternative epistemological picture, which I call ‘introverted empiricism,’ and presents the way it provides for a more satisfying grasp of the ultimate nature of objects, properties, and causation. It is a consequence of this alternative picture that there is a kind of intimate self-understanding that underlies our understanding of the deep nature of reality. (shrink)

This paper considers the place of reasons in the metaphysics of epistemic normativity and defends a middle ground between two popular extremes in the literature. Against members of the ‘reasons first’ movement, we argue that reasons are not the sole fundamental constituents of epistemic normativity. We suggest instead that the virtue-theoretic property of competence is the key building block. To support this approach, we note that reasons must be possessed to play a role in the analysis of central epistemically (...) normative properties, and argue that the relation of possession must be analyzed in terms of competence. But while we diverge with reasons-firsters on this score, we also distance ourselves from those who deny reasons any important role in epistemology. For we maintain that possessed reasons do help to ground deontic facts in the epistemic domain (e.g., facts about what one epistemically ought to believe, may believe, or is justified in believing). Indeed, we present an argument that the possession of sufficient epistemic reasons is necessary and sufficient for propositional justification, and that proper basing on such reasons yields doxastic justification. But since possession and proper basing are themselves grounded in competence, reasons are not the end of the explanatory road: competence enables them to do their work, putting them—and us—in the middle.

Presence as ordinarily understood requires spatio-temporal proximity. If however Christ’s presence in the Eucharist is understood in this way it would take a miracle to secure multiple location and an additional miracle to cover it up so that the presence of Christ where the Eucharist was celebrated made no empirical difference. And, while multiple location is logically possible, such metaphysical miracles—miracles of distinction without difference, which have no empirical import—are problematic. I propose an account of Eucharist according to which Christ (...) is indeed really and objectively present in the religiously required sense, without benefit of metaphysical miracles. According to the proposed account, which draws upon Searle’s discussion of “social ontology” in The Construction of Social Reality and The Making of the Social World, the presence of Christ in the Eucharist is an institutional fact. I argue that such an account satisfies the requirements for a real presence doctrine. (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)
