The present paper discusses different approaches to metaphysics and defends a specific, non-deflationary approach that nevertheless qualifies as scientifically-grounded and, consequently, as acceptable from the naturalistic viewpoint. By critically assessing some recent work on science and metaphysics, we argue that such a sophisticated form of naturalism, which preserves the autonomy of metaphysics as an a priori enterprise yet pays due attention to the indications coming from our best science, is not only workable but recommended.

In this paper I return to the mid-20th-century debate between Quine and Carnap on the status of metaphysics questions with an eye toward advancing contemporary debates about whether naturalists can coherently undertake substantive metaphysical inquiry. Following Huw Price, I take the debate between Quine and Carnap to hinge, in part, on whether human inquiry is functionally unified. However, unlike Price, I suggest that this question is not best understood as a question about the function(s) of descriptive discourse. This goes (...) along with rejecting a “linguistic conception” of the starting point of metaphysical inquiry, which, although shared by Quine and Carnap, Price gives us no good reason to think is mandatory for naturalists. I sketch two reasons naturalists have to reject a particular manifestation of this linguistic conception in Quine’s work—his criterion of ontological commitment. Finally, I show how these reasons can help us identify the grains of truth in some recent critiques of “mainstream metaphysics of mind.”. (shrink)

Critics of Dewey’s metaphysics point to his dismissal of any philosophy which locates ideals in a realm beyond experience. However, Dewey’s sustained critique of dualistic philosophies is but a first step in his reconstruction and recovery of the function of the metaphysical. Detaching the discussion of values from inquiry, whether scientific, philosophical or educational, produces the same end as relegating values to a transcendent realm that is beyond ordinary human discourse. Dewey’s naturalistic metaphysics supports his progressive educational philosophy. (...) The duty of education is grounded in its service to democracy; it must help students develop the ability to express, discuss, and develop their moral reasoning through experiential and experimental learning.

How does the philosophical debate between naive realism and intentionalism relate to the psychological debate between ecological theories and constructivist theories? The participants in each debate take themselves to be doing something distinctive, but I show that characterizing the distinction is difficult: the theories in both debates use inference to the best explanation to draw contingent conclusions about the constitutive nature of perception. I argue that both debates concern the metaphysics of perception, and that philosophers of perception are wrong (...) to think that constructivist and ecological theories are engaged in a distinct and non-metaphysical task. (shrink)

The disciplinary characterisation (DC) is the most popular approach to defining metaphysical naturalism and physicalism. It defines metaphysical naturalism with reference to scientific theories and defines physicalism with reference to physical theories, and suggests that every entity that exists is a posited entity of these theories. DC has been criticised for its inability to solve Hempel’s dilemma and a list of problems alike. In this paper, I propose and defend a novel version of DC that can be called (...) a historical paths approach. The idea is (roughly) that metaphysical naturalism can be defined with reference to the historical ideas that current scientific ideas descend from. I argue that it is not rendered implausible by the above problems, and hence that DC is more defensible and attractive than it may first appear. I then argue that the approach also provides a useful framework for the naturalisation of the philosophy of mind and phenomenology. (shrink)

This chapter examines the status of inference to the best explanation in naturalistic metaphysics. The methodology of inference to the best explanation in metaphysics is studied from the perspective of contemporary views on scientific explanation and explanatory inferences in the history and philosophy of science. This reveals serious shortcomings in prevalent attempts to vindicate metaphysical "explanationism" by reference to similarities between science and naturalistic metaphysics. This critique is brought out by considering a common gambit of methodological unity: (...) (1) Both metaphysics and science employ inference to the best explanation. (2) One has no reason to think that if explanationism is truth-conducive in science, it is not so in metaphysics. (3) One has a positive reason to think that if explanationism is truth-conducive in science, it is also so in metaphysics. (shrink)

In this paper I discuss the nature of halakhic facts and I frame the discussion in a broader meta-ethical context. Most of the existing literature on the philosophy of halakha has focused on the contrast between ‘Halakhic Realism’ and ‘Halakhic Nominalism’. This theoretical contrast is vague and includes a wide range of theories. Inspired by the meta-ethical literature, I propose to focus the discussion on views that can be called ‘Halakhic Naturalism’ and ‘Halakhic Non-naturalism’. I present, develop and (...) distinguish between different meanings of 'naturalism' and consider arguments for and against 'Halakhic Naturalism'. The purpose of this paper is twofold: First, to present and demonstrate the fruitful encounter between meta-ethics and the philosophy of halakha. Second, to present, evaluate and promote the substantive discussion of naturalistic and non-naturalistic views. (shrink)

This paper offers a defence of metaphysical naturalism, in the context of the Fine Tuning argument. Theistic objections to the Multiverse (MV) hypothesis are considered, specifically the claim that the MV hypothesis commits the Inverse Gambler’s Fallacy (IGF) and, as per the This Universe Objection (TUO), that it violates the Requirement of Total Evidence. It is argued that the IGF claim moved the goalposts when it comes to assessing the validity of the MV hypothesis. The Cosmic Slot Machine analogy (...) will be used to demonstrate how the This Universe Objection (TUO), fails to adequately account for the anthropic principle (or selection effect) and how the MV hyptothesis does satisfy the Requirement for Total Evidence. -/- With respect to the Naturalistic Single Universe (NSU), the implications of the ex-nihilonihil- fit principle, for evaluating the epistemic probability of a Life Permitting Universe (LPU)under the NSU hypothesis, are considered. It is argued that the ex nihilo nihil fit principle entails that an LPU is not improbable under the NSU hypothesis. (shrink)

Normative naturalism is primarily a metaphysical doctrine: there are normative facts and properties, and these fall into the class of natural facts and properties. Many objections to naturalism rely on additional assumptions about language or thought, but often without adequate consideration of just how normative properties would have to figure in our thought and talk if naturalism were true. In the first part of the paper, I explain why naturalists needn’t think that normative properties can be represented (...) or ascribed in wholly non-normative terms. If so, certain prominent objections to normative naturalism fail. In the second part, I consider the objection that normative properties are “just too different” from (other) natural properties to themselves be natural properties. I argue that naturalists have no distinctive trouble making sense of thought and talk involving forms of “genuine” or “authoritative” normativity which can drive a non-question-begging form of the objection.

This paper addresses a fundamental question in folk metaphysics: how do we ordinarily view human agency? According to the transcendence account, we view human agency as standing outside of the causal order and imbued with exceptional powers. According to a naturalistic account, we view human agency as subject to the same physical laws as other objects and completely open to scientific investigation. According to exceptionalist naturalism, the truth lies somewhere in between: we view human agency as fitting broadly (...) within the causal order while still being exceptional in important respects. In this paper, I report seven experiments designed to decide between these three competing theories. Across a variety of contexts and types of action, participants agreed that human agents can resist outcomes described as inevitable, guaranteed, and causally determined. Participants viewed non-human animal agents similarly, whereas they viewed computers, robots, and simple inanimate objects differently. At the same time, participants judged that human actions are caused by many things, including psychological, neurological, and social events. Overall, in folk metaphysics, human and non-human animals are viewed as exceptional parts of the natural world. (shrink)

The following scenario seems possible: a community uses concepts that play the same role in guiding actions and shaping social life as our normative concepts, and yet refer to something else. As Eklund argues, this apparent possibility poses a problem for any normative realist who aspires to vindicate the thought that reality itself favors our ways of valuing and acting. How can realists make good on this idea, given that anything they might say in support of the privileged status of (...) our normative concepts can be mirrored by the imagined community? E.g., the realist might claim that using our concepts is what we ought to do if we are to describe normative facts correctly, but members of the other community can claim the same about their concepts, using their own concept of ought. A promising approach to this challenge is to try to rule out the possibility of alternative normative concepts, by arguing that any concepts that have the same normative role must share a reference as well. In this paper I argue that normative quasi-naturalism, a view that combines expressivism about normative discourse with a naturalist metaphysics of normativity, supports referential normativity and solves the problem of alternative normative concepts.

In this précis I summarise the main ideas of my book Philosophy of Psychedelics. The book discusses philosophical issues arising from the therapeutic use of “classic” psychedelic drugs such as psilocybin and LSD. The book is organised around what I call the Comforting Delusion Objection to psychedelic therapy: the concern that this novel and promising treatment relies essentially on the induction of non-naturalistic metaphysical beliefs, rendering it epistemically objectionable. I begin the précis by summarizing material from chapters two and three (...) of the book, which review evidence for the therapeutic efficacy of psychedelics, and the facts about their clinical use that prompt the Comforting Delusion Objection. I then summarize materials from chapters four and five of the book, which argue that psychedelic therapy works neither by experience-independent processes of neuroplasticity, nor by inducing non-naturalistic metaphysical ideations, but by altering mental representations of the self. Next, I summarise the specific, speculative account of how this might work that is developed in chapters six and seven of the book. This account is based on the predictive processing theory of brain function and the self-binding theory of self-representation. Chapters eight and nine of the book argue, on the basis of this account, that psychedelic therapy can have significant epistemic and spiritual benefits that are compatible with a naturalistic worldview. I summarize this material, and then, finally, the overall conclusions about psychedelic therapy drawn in the tenth and final chapter of the book. (shrink)

There are few who would deny that P. F. Strawson’s “Freedom and Resentment” (1962) ranks among the most significant contributions to modern moral philosophy. Although any number of essays have been devoted to it, Pamela Hieronymi’s 'Freedom, Resentment, and the Metaphysics of Morals' is the first book-length study. The aim of Hieronymi’s study is to show that Strawson’s “central argument” has been “underestimated and misunderstood.” Hieronymi interprets this argument in terms of what she describes as Strawson’s “social naturalism”. (...) Understood this way, Hieronymi maintains, “the argument is powerful”. In what follows I argue that while Hieronymi’s discussion is stimulating and provides valuable insights into “Freedom and Resentment,” neither the interpretation advanced nor the social naturalist position that it describes is convincing.

As neither a classical naturalist nor a non-naturalist, Merleau-Ponty appears to be a moderate or liberal naturalist. But can a phenomenologist really be a naturalist, even a liberal one? A lot hinges on how we tease this out, both as to whether it is plausible to claim Merleau-Ponty as a liberal naturalist (I argue it is), and as to whether it is an attractive and coherent position. Indeed, despite its important challenges to orthodox naturalism, there are arguably two traps (...) to avoid. If it becomes too liberal, we get: dualism or an ontological pluralism that is difficult to distinguish from a constructivism; or, in seeking to sidestep that metaphysical dilemma, there is sometimes an insistence on an overly neat methodological separation between description/understanding and explanation that is belied in practice (both scientific and philosophical). It is doubtful that such positions can legitimately claim to be naturalist in orientation, liberal or not. Merleau-Ponty’s philosophy avoids these traps, however, and it is thus a useful resource for contemporary work trying to navigate between scientific naturalism and non-naturalism. (shrink)

The paper examines Derek Parfit’s claim that naturalism trivializes the agent’s practical argument and therefore abolishes the normativity of its conclusion. In the first section, I present Parfit’s charge in detail. After this I discuss three possible responses to the objection. I show that the first two responses either fail or are inconclusive. Trying to avoid Parfit’s charge by endorsing irreductionist naturalism is not a solution because this form of naturalism is metaphysically untenable. Non- descriptive naturalism, (...) on the other hand, does not answer the pressing concern behind Parfit’s charge. I conclude that we had better turn to the third response: Peter Railton’s vindicatory reductionism. However, I also argue that naturalism can only avoid triviality in this way if it is able to respond to further challenges concerning the vindication of the reduction it proposes. Hence, though not a knockdown argument as it is intended to be, Parfit’s charge can still pose a threat to naturalist accounts of normativity. (shrink)

The term ‘naturalism’ has a long and complex history in modern philosophy. W.V.O. Quine famously advocated what has come to be known as a ‘naturalistic turn’ for philosophy as a discipline, meaning that philosophical thought should become continuous with the natural sciences – even claiming that epistemology (theory of knowledge) is nothing but applied psychology.

I offer a minimal characterization of naturalism, with ontological, epistemological, psychological and evaluative dimensions. I explain why naturalism is attractive. I note that naturalists disagree among themselves about, among other things, the nature of values, beliefs, and abstractions. I close by responding to some standard objections to naturalism.

In this paper, I lay the groundwork for a new account of progress in metaphysics, the ‘tool building approach’. The account is born out of a response to the problem of theory-change for naturalistic metaphysics. Kerry McKenzie (2020) makes clear the problem of theory-change for naturalistic metaphysics. She argues that naturalistic metaphysical theories cannot make progress on the back of scientific theories because metaphysical theories cannot be approximately true. First, I apply a well-known account of scientific progress, (...) the truthlikeness account of progress, to theories in metaphysics in order to show that metaphysics can make progress on such an account. This account, however, will not fully address the issue of radically changing theories over theory-change. Then, I offer a new account of progress in metaphysics, the tool building approach, that specifies the progress metaphysics makes even if our best naturalistic theories in metaphysics radically change.

This chapter offers an introduction to naturalist views in contemporary metaethics. Such views attempt to find a place for normative properties (such as goodness and rightness) in the concrete physical world as it is understood by both science and common sense. The chapter begins by introducing simple naturalist conceptual analyses of normative terms. It then explains how these analyses were rejected in the beginning of the 20th Century due to G.E. Moore’s influential Open Question Argument. After this, the chapter considers (...) what good general reasons there are for defending naturalism in metaethics. The bulk of the chapter will then survey new semantic and metaphysical forms of naturalism which in different ways attempt to address Moore’s objection to naturalism. These more recent versions of naturalism—using new resources from philosophy of language, philosophy of mind, metaphysics, philosophy of science and epistemology—attempt to explain why the Open Question Argument fails.

Several metaphysical naturalists argue that the success of science, together with the claim that scientists adhere to methodological naturalism, amounts to strong evidence for metaphysical naturalism. I call this the scientific-success argument. It is argued that the scientific-success argument is similar to the no-miracles argument for realism in philosophy of science. On the no-miracles argument, the success of science is taken as strong evidence that scientific theories are true. Based on this similarity, some considerations relevant to one argument (...) may also be relevant to the other. One particular consideration is explored. The selectionist response to the no-miracles argument states that on an evolutionary model of science, in which scientific theories are accepted only after surviving a rigorous selection process, the no-miracles argument fails. The selectionist response also applies to the scientific-success argument. If scientific theories are selected for success, we do not need to explain the success of science by appealing to metaphysical naturalism. (shrink)

A core tenet of metanormative non-naturalism is that genuine or robust normativity—i.e., the kind of normativity that is characteristic of moral requirements, and perhaps also of prudential, epistemic and even aesthetic requirements—is metaphysically special in a way that rules out naturalist analyses or reductions; on the non-naturalist view, the normative is sui generis and metaphysically discontinuous with the natural. Non-naturalists agree, however, that the normative is modally as well as explanatorily dependent on the natural. These two commitments—discontinuity and dependence—at (...) least initially pull in opposite directions, and one of the central challenges to non-naturalism is how to reconcile them. In this paper I spell out the most pressing version of this discontinuity problem, as I propose to call it, and I go on to offer a novel solution. Drawing on the ideology of reasons-firstism, I formulate an account of normative explanation which reconciles the two commitments, and I argue that competing accounts either do not solve the problem or are implausible on independent grounds.

This is a critical, but sympathetic, examination of the manifesto for naturalized metaphysics that forms the first chapter of James Ladyman and Don Ross's 2006 book, Every Thing Must Go, but it has wider implications than this description suggests.

This paper takes up an important epistemological challenge to the naturalistic moral realist: that her metaphysical commitments are difficult to square with a plausible rationalist view about the epistemology of morality. The paper begins by clarifying and generalizing this challenge. It then illustrates how the generalized challenge can be answered by a form of naturalistic moral realism that I dub joint-carving moral realism. Both my framing of this challenge and my answer advertise the methodological significance of non-fundamental epistemological theorizing, which (...) defends and deploys epistemological claims without adverting to the most fundamental epistemological facts.

Quantum theory offers mathematical descriptions of measurable phenomena with great facility and accuracy, but it provides absolutely no understanding of why any particular quantum outcome is observed. It is the province of genuine explanations to tell us how things actually work—that is, why such descriptions hold and why such predictions are true. Quantum theory is long on the what, both mathematically and observationally, but almost completely silent on the how and the why. What is even more interesting is that, in (...) some sense, this state of affairs seems to be a necessary consequence of the empirical adequacy of quantum descriptions. One of the most noteworthy achievements of quantum theory is the accurate prediction of phenomena that, on pain of experimental contradiction, have no physical explanation. It is the purpose of this essay to make clear why quantum mechanics and quantum field theory are complete physical descriptions that describe the metaphysical incompleteness of the physical world, then to press the negative implications of this fact for naturalistic metaphysics.

Huw Price has argued that naturalistic philosophy inevitably leads to a deflationary approach to ontological questions. In this paper, I rebut these arguments. A more substantive, less language-focused approach to metaphysics remains open to naturalists. However, rebutting one of Price’s main arguments requires rejecting Quine’s criterion of ontological commitment. So, even though Price’s argument is unsound, it reveals that naturalists cannot rest content with broadly Quinean, “mainstream metaphysics,” which, I suggest, naturalists also have independent reasons to reject.

This book addresses the metaphysics of Armstrongian states of affairs, i.e. instantiations of naturalist universals by particulars. The author argues that states of affairs are the best candidate for truthmakers and, in the spirit of logical atomism, that we need no molecular truthmakers for positive truths. In the book's context, this has the pleasing result that there are no molecular states of affairs. Following this account of truthmaking, the author first shows that the particulars in (first-order) states of affairs (...) are bare particulars. He then argues that the properties in states of affairs are simple, non-relational and concrete universals. Next, he argues that (material) relations in states of affairs are external relations. Lastly, he argues that a state of affairs is unified by a distinctive formal relation without giving rise to Bradley’s regress. (shrink)

Naturalism has typically been entangled with a physicalist view. Physicalism, on the other hand, falls short of accounting for qualitative states of mental phenomena. The hard problem of consciousness seems to be a natural epistemic boundary in such a way that we do not even have any conceptualization as to how we can possibly account for mental states in physicalist terms in the future, which leads us to some version of causal/ontological plurality in the sense that it does not (...) seem possible to explain everything with the same parameters even though the world fundamentally consists in a single substance. If plurality in multiple levels of scientific explanation is necessary, I argue that strong emergentism is, as a metaphysical framework, the best candidate to account for this fact. I will tackle two major physicalist views by Kim and Sider. Kim shows us that non-reductive physicalism is a bankrupt project whereas Sider’s physicalism that postulates a pure and complete fundamental level renders higher-level phenomena (including mental reality) metaphysically spurious. In relation to Kim and Sider’s accounts, I will try to elaborate on my view that physicalism, when pursued to the end, is inherently reductive and ultimately falls short of accounting for the mental reality. I emphasize that the causal identification of brain and mind rests on an arbitrary carving of world, namely a description of the world which cannot be intrinsic to nature. These are the main reasons why I conclude that our revised naturalism should be disentangled from physicalism and embrace the causal/ontological plurality of strong emergentism without falling for substance dualism.

[ROYAL INSTITUTE OF PHILOSOPHY 2023 ESSAY PRIZE WINNER] I argue that the term ‘naturalism’ is so empty of meaning that it is not suitable for serious theorizing in philosophy. In particular, I argue that the question of whether or not some theory or thesis should count as naturalistic is an empty verbal dispute with no further theoretical significance. I also discuss naturalism construed as a methodological thesis and argue that any plausible version will collapse into triviality. Lastly, I (...) briefly discuss the idea that naturalism is not a thesis at all but rather a ‘stance’ and suggest that this too succumbs to the charge of emptiness. I conclude that we should stop talking about naturalism altogether. (shrink)

Neo-Aristotelian naturalism purports to explain morality in terms of human nature, while maintaining that the relevant aspects of human nature cannot be known scientifically. This has led some to conclude that neo-Aristotelian naturalism is not a form of ethical naturalism in the standard, metaphysical sense. In this paper, I argue that neo-Aristotelian naturalism is in fact a standard form of ethical naturalism that is committed to metaphysical naturalism about moral truths and presents a distinctive (...) and underappreciated argument for it. I reconstruct the neo-Aristotelian argument for ethical naturalism in terms of a continuity between the ethical domain and the natural domain of life. I argue that clarifying the meta-ethical import of neo-Aristotelian naturalism not only helps to situate it among other positions in meta-ethics, but also facilitates better critical engagement with the view. (shrink)

It is common in metaethics today to draw a distinction between “naturalist” and “non-naturalist” versions of moral realism, where the former view maintains that moral properties are natural properties, while the latter view maintains that they are non-natural properties instead. The nature of the disagreement here can be understood in different ways, but the most common way is to understand it as a metaphysical disagreement. In particular, the disagreement here is about the reducibility of moral properties, where the “naturalists” maintain (...) that moral properties are in some way reducible to the lower-level natural properties on which they supervene, while the “non-naturalists” maintain that moral properties are sui generis and robustly irreducible. In this paper I present a novel version of realist ethical naturalism—a view that I call Emergentist Ethical Naturalism—that reveals this common way of understanding the distinction between naturalism and non-naturalism to be flawed by combining a commitment to ethical naturalism with a commitment to the sui generis and robustly irreducible nature of moral properties that typically defines non-naturalism. Then, after presenting the theory and addressing a few worries that one might have about it, I show how it offers some novel, emergence-based responses to the various supervenience challenges that plague moral realism and thereby gives the ethical naturalist a robustly non-reductive option for dealing with these challenges.

Contemporary naturalism has two components. The first is ontological, and says, roughly, that all and only what the sciences say exists, really does exist. The other is methodological, and it says that only scientific explanations are legitimate explanations. Together these commitments promise a coherent picture of the world that is nicely integrated with an attractive epistemology. Despite the obvious appeal of naturalism, I would like to sound a note of caution. First, I would like to argue that (...) class='Hi'>naturalism's ontological commitment cannot be vindicated. Not, that is, that it is false; rather, I argue that any attempt to show that it is true presupposes that it is not. Second, I argue that methodological naturalism is false. But, again, the problem is not straightforward. I will not claim that there are gaps in the explanations offered by science, such that the scientific project would be incomplete without emendation. Instead I argue that the goodness of an explanation depends, in part, on how the event to be explained is described, and that, some events, under some descriptions, call for non-scientific explanations.

In my recent book, Art and Engagement (1991), I develop the idea of aesthetic engagement as central to the appreciation of art. The human contribution to the constitution of the "work" of art, I claim, is a critical part of appreciative experience. This contribution, however, is easily misread into the history of the idea of experience that has dominated Western philosophy since the seventeenth century, a history that sees experience as an inner, personal, subjective affair. From this vantage point, the (...) metaphysical implications of an aesthetics of experience seem to lead resolutely to idealism.1 'Experience', however, is a troublesome term precisely because its meaning is equivocal. Despite its association with philosophical idealism, experience allows a range of interpretations in various contexts. Even though aesthetic experience is often understood subjectively, it is mistaken to think that it allows of no other alternative. These comments raise a complex of issues, two of which I want to consider here: first, the metaphysical significance of experience and, second, the bearing of art on metaphysics. (shrink)

During the past few decades, a radical shift has occurred in how philosophers conceive of the relation between science and philosophy. A great number of analytic philosophers have adopted what is commonly called a ‘naturalistic’ approach, arguing that their inquiries ought to be in some sense continuous with science. Where early analytic philosophers often relied on a sharp distinction between science and philosophy—the former an empirical discipline concerned with fact, the latter an a priori discipline concerned with meaning—philosophers today largely (...) follow Willard Van Orman Quine (1908-2000) in his seminal rejection of this distinction. -/- This book offers a comprehensive study of Quine’s naturalism. Building on Quine’s published corpus as well as thousands of unpublished letters, notes, lectures, papers, proposals, and annotations from the Quine archives, this book aims to reconstruct both the nature (chapters 2-4) and the development (chapter 5-7) of his naturalism. As such, this book aims to contribute to the rapidly developing historiography of analytic philosophy, and to provide a better, historically informed, understanding of what is philosophically at stake in the contemporary naturalistic turn.

[English abstract] In his last metaethical statement, Parfit revisits his earlier arguments for non-metaphysical normative non-naturalism , and points to the possibility of convergence between his view and Railton's non-analytical normative naturalism. I examine the basis of this convergence claim and find it unpersuasive, mainly because if their views converge on the same position, Parfit's non-natural norms exist only as predicates. In order to avoid this consequence, he needs to present a reason for believing in the existence of (...) normative properties . There is an indispensability argument implicit in his text, with concepts of sui generis normative ground and necessity at its centre. I discuss their main features and present problems besetting these concepts. (shrink)

The Fine-Tuning Argument (FTA) is an argument put forward by proponents of theism, in which they attempt to make a case from Bayesian inference, that the [apparently] fine tuned constants of our universe is more likely given a theistic hypothesis, than a naturalistic one. Some naturalists argue that this is not the case given the Multiverse (MV) hypothesis (that our universe is one of a plurality in a broader multiverse). The MV hypothesis is rejected by theists who argue it commits (...) what Ian Hacking (1987) referred to as “the Inverse Gambler’s Fallacy”. In this paper I will attempt to demonstrate [what I perceive as] the errors in logic made by theists first in positing that a life-permitting universe (LPU) is improbable under the naturalistic-single-universe (NSU) hypothesis, and subsequently the errors in arguing that the MV hypothesis commits what Ian Hacking (1987) referred to as “the Inverse Gambler’s Fallacy”. First, I will attempt to demonstrate why an LPU is not improbable under the NSU. Second, I will attempt to demonstrate that if we ascribe a probability value to our LPU, we can directly infer either an MV or the existence of “Deeper Laws” (Barnes, 2020) from that probability value.

John Dewey's metaphysics of experience has been criticized by a number of philosophers-most notably, George Santayana and Richard Rorty. While mainstream Dewey scholars agree that these critical treatments fail to treat the American Pragmatist theory of what exists on its own terms, there has still been some difficulty reaching consensus on what the casual reader should take away from the pages of Experience and Nature, Deweys seminal work on naturalistic metaphysics. So, how do we unearth the significance of (...) Dewey's misunderstood metaphysics? One way is for philosophers to look to spatial and social-cultural geographers for help. To fully grasp the movement of experience, these geographers recommend that we start with an experiential activity, such as touring. The activity of sea kayak touring, I contend, discloses the general movement of experience in Dewey's metaphysics between its primary and secondary phases. With this illustration and a closely connected metaphor, I demonstrate that Dewey's naturalized metaphysics can not only withstand the objections of the likes of Santayana and Rorty it can also assist us in gaining a deeper appreciation of the qualitative richness of our own day-to-day practices.

Scientific knowledge is not merely a matter of reconciling theories and laws with data and observations. Science presupposes a number of metatheoretic shaping principles in order to judge good methods and theories from bad. Some of these principles are metaphysical (e.g., the uniformity of nature) and some are methodological (e.g., the need for repeatable experiments). While many shaping principles have endured since the scientific revolution, others have changed in response to conceptual pressures both from within science and without. Many of (...) them have theistic roots. For example, the notion that nature conforms to mathematical laws flows directly from the early modern presupposition that there is a divine Lawgiver. This interplay between theism and shaping principles is often unappreciated in discussions about the relation between science and religion. Today, of course, naturalists reject the influence of theism and prefer to do science on their terms. But as Robert Koons and Alvin Plantinga have argued, this is more difficult than is typically assumed. In particular, they argue, metaphysical naturalism is in conflict with several metatheoretic shaping principles, especially explanatory virtues such as simplicity and with scientific realism more broadly. These arguments will be discussed as well as possible responses. In the end, theism is able to provide justification for the philosophical foundations of science that naturalism cannot. (shrink)

I proffer a success argument for classical logical consequence. I articulate in what sense that notion of consequence should be regarded as the privileged notion for metaphysical inquiry aimed at uncovering the fundamental nature of the world. Classical logic breeds necessitism. I use necessitism to produce problems for both ontological naturalism and atheism.

Traditionally, being a realist about something means believing in the independent existence of that something. In this line of thought, a scientific realist is someone who believes in the objective existence of the entities postulated by our best scientific theories. In metaphysical terms, what does that mean? In ontological terms, i.e., in terms of what exists, scientific realism can be understood as involving the adoption of a scientifically informed ontology. But according to some philosophers, a realistic attitude must go beyond (...) ontology. The way in which this requirement has been understood involves providing a metaphysics for the entities postulated by science, that is, answering questions about the nature of what ontology admits to exist. We discuss how two fashionable approaches face the challenge of providing a metaphysics for science: a form of naturalism and the Viking/Toolbox approach. Finally, we present a third way, which adopts the best of both approaches: the meta-Popperian method, which focuses on discarding the wrong alternatives, or better saying, the metaphysical profiles incompatible with certain theories. We present the meta-Popperian method, a metametaphysical method capable of objectively assessing which metaphysical profiles are incompatible with certain scientific theories. For this, we will use quantum mechanics as a case study, presenting some previously obtained results. As our focus is on methodological questions about the relationship between metaphysics and science; with this method, we can see how science can be used to avoid error in metaphysical issues. In our opinion, this would be a way to develop a productive relationship between science and metaphysics. (shrink)

Recent years have seen a Bayesian revolution in cognitive science. This should be of interest to metaphysicians of science, whose naturalist project involves working out the metaphysical implications of our leading scientific accounts, and in advancing our understanding of those accounts by drawing on the metaphysical frameworks developed by philosophers. Toward these ends, in this paper I develop a metaphysics of the Bayesian mind. My central claim is that the Bayesian approach supports a novel empirical argument for normativism, the (...) thesis that belief has a normative essence, with the norms in question being those of rationality. The argument I develop draws in part on the causal powers subset account of realization defended by Wilson and Shoemaker, with the link being that Bayesians often appeal to Marr’s framework of levels of analysis, which carries with it multiple realizability claims that can be understood in terms of the subset model. I then use the view developed, with its appeal to normativism and subset realization, to explain how Bayesians can accommodate empirical findings of irrationality that are sometimes thought to pose a problem for their view.

Metaethical non-analytical naturalism consists in the metaphysical thesis that normative properties are identical with or reducible to natural properties and the epistemological thesis that we cannot come to a complete understanding of the nature of normative properties via conceptual analysis alone. In On What Matters, Derek Parfit (2011) argues that non-analytical naturalism is either false or incoherent. In § 1, I show that his argument for this claim is unsuccessful, by showing that it rests on a tacit assumption (...) about the nature of normative thought that non-analytical naturalists need not accept. In § 2, I show that escaping Parfit’s argument in this way is no ad hoc maneuver; as I demonstrate, the idea that non-analytical naturalists can exploit to escape Parfit’s argument is a familiar one.

History and the modern sciences are characterized by what is sometimes called a methodological naturalism that disregards talk of divine agency. Some religious thinkers argue that this reflects a dogmatic materialism: a non-negotiable and a priori commitment to a materialist metaphysics. In response to this charge, I make a sharp distinction between procedural requirements and metaphysical commitments. The procedural requirement of history and the sciences—that proposed explanations appeal to publicly-accessible bodies of evidence—is non-negotiable, but has no metaphysical implications. (...) The metaphysical commitment is naturalistic, but is both a posteriori and provisional, arising from the fact that for more than 400 years no proposed theistic explanation has been shown capable of meeting the procedural requirement. I argue that there is nothing to prevent religious thinkers from seeking to overturn this metaphysically naturalistic stance. But in order to do so they would need to show that their proposed theistic explanations are the best available explanations of a range of phenomena. Until this has been done, the metaphysical naturalism of history and the sciences remains defensible. (shrink)

I first present what Peter Strawson calls his “Social Naturalism,” as applied to ethics. I then briefly present the way in which his Naturalism allows Strawson to resist skepticism about moral responsibility and free will, as argued in “Freedom and Resentment.” His way of resisting this kind of skepticism opens his Naturalism to another challenge: it can seem objectionably relativistic. I have provided a response to this challenge, on Strawson’s behalf, in the final chapter of my _Freedom, (...) Resentment, and the Metaphysics of Morals_ (2020). In this paper I expand upon that response—in particular, on the way in which the introduction of admittedly contested ideals might provide sufficient critical purchase to avoid objectionable relativism while remaining broadly naturalistic.

I develop a psychological account for how it is that we use imagination to metaphysically modalize, i.e., to reach conclusions about metaphysical modality. Specifically, I argue that Nichols and Stich’s (2003) cognitive theory of imagination can be extended to metaphysical modalizing. I then use the extension to explicate philosophical disagreements about whether a scenario is metaphysically possible. Thereafter, I address Nichols’ (2006) objection that psychologizing imagination makes it clear that imagination is unreliable when used to metaphysically modalize. The end result (...) is a naturalistic account for how imagination enables us to metaphysically modalize. (shrink)

The purpose of this paper is to examine the relationship between naturalism and morality and to assess their compatibility. Naturalism is defined as respect for science, for its methods and results. From this respect for science, one can infer two distinct philosophical naturalisms: the methodological and the metaphysical. The relationship between these forms of naturalism and morality depends on the correct conception of morality. This paper differentiates between objectively realistic conception and all other conceptions and argues that (...) while other conceptions can easily fit morality into a naturalistic worldview, objectively realistic conception faces theoretical challenges, including the challenge of explaining how moral facts and concepts play an explanatory role and the challenge of bridging the is/ought gap. The paper focuses on Railton's ethical naturalism as a prominent naturalistic theory of morality and evaluates its ability to overcome these challenges. The conclusion is that, so long as we consider a theory like Railton's, naturalism and realistically conceived morality are incompatible. (shrink)

Nietzsche has been associated with naturalism due to his arguments that morality, religion, metaphysics, and consciousness are products of natural biological organisms and ultimately natural phenomena. The subject and its mental life are only comprehensible in relation to natural desires, drives, impulses, and instincts. I argue that such typical natu-ralizing tendencies do not exhaust Nietzsche’s project, since they occur in the context of his critique of “nature” and metaphysical, speculative, and scientific naturalisms. Nie-tzsche challenges otherworldly projections of this-worldly (...) beings, as his naturalistic in-terpreters claim, but further the idolization of immanent worldly natural phenomena, in-cluding science itself. “Nature” is an idealization of natural organisms and environments in which its construction, projection, and interpretation is forgotten. Nietzsche strategical-ly uses naturalistic scientific strategies of explanation and demystification, while demys-tifying science, positivism, and naturalism for the sake of life. These do not provide either certainties or foundations for knowledge or life. Naturalism would be anti-natural if it denies of multiplicity and conflict of the forces of life, bracketing the natural and his-torical conditions of existence, and the interpretive and perspectival character of life and knowledge. The nexus of nature and history in Nietzsche is better clarified through his portrayal of the feeling of life and its intensification, attenuation, and transformation in relation to the forces and conditions of life, which encompass processes of socialization and interpretive and artistic individuation in the context of a life.

Elisabeth was the first of Descartes' interlocutors to press concerns about mind-body union and interaction, and the only one to receive a detailed reply, unsatisfactory though she found it. Descartes took her tentative proposal `to concede matter and extension to the soul' for a confused version of his own view: `that is nothing but to conceive it united to the body. Contemporary commentators take Elisabeth for a materialist or at least a critic of dualism. I read her instead as a (...) dualist of a different variety from Descartes: a forerunner of twenty-first century naturalistic dualism which calls for empirical investigation of the psychological and its posits to be taken just as seriously as physics and its posits. -/- I argue that Elisabeth, a keen scholar of mechanistic physics, objected not to substance dualism per se but to the residual Scholasticism of Descartes' account of mind-body causality and his dogmatism about principal attributes. She queried Descartes' categorisation of the `action' of thought as mind's principal attribute, and his identification of it with the merely negative property of immateriality, holding instead that further philosophical and empirical investigation into the nature of the mind is necessary. I problematise the materialist interpretation of Elisabeth with reference to later letters where she dismissed the materialist Objections of Hobbes and Gassendi and continued to urge further clarifications to Cartesian dualism. I explore Elisabeth's contrasting of statements of mechanistic physics with statements about thought, and her call for further investigation into the properties of the mind, and argue they mark her out as a forerunner of contemporary naturalistic dualism which proposes substance dualism as a best interpretation of recent psychology and of the difference in logical form between current physics and current psychology.

Contemporary naturalism is changing and scientific reductionism is under challenge from those who advocate a more comprehensive outlook. This special issue of Telos, based on the first Telos Australia Symposium held at Swinburne University in Melbourne in February 2014, introduces some of the key questions in the current debates. It also poses the question of whether more satisfactory political and social thought can be produced if scientific reductionism is replaced by a richer and more hermeneutical naturalism, one that (...) takes more account of philosophical anthropology, actual co-involvements of human beings and their environments, and the potential of more naturalistically grounded approaches to culture.

Michael Devitt’s views on realism and naturalism have a lot in common with those of W.V. Quine. Both appear to be realists; both accept naturalized epistemology and abandon the old goal of first philosophy; both view philosophy as continuous with the empirical procedures of science and hence view metaphysics as similarly empirical; and both seem to view realism as following from naturalism. Although Quine and Devitt share quite a bit ideologically, I think there is a deeper, more (...) fundamental dissimilarity between the two. I will explore the difference between them in an attempt to bring out the subtle complexities surrounding the issue of realism--complexities, I will argue, Devitt sometimes overlooks. I will also explore a real tension in Quine between his earlier, more pragmatic (or anti-realist) tendencies and his later, more austere realism. I will conclude by defending a more Quinean brand of realism I call internal realism. (shrink)
