After rejecting substance dualism, some naturalists embrace patternism. It states that persons are bodies and that bodies are material machines running abstract person programs. Following Aristotle, these person programs are souls. Patternists adopt four-dimensionalist theories of persistence: Bodies are 3D stages of 4D lives. Patternism permits at least six types of life after death. It permits quantum immortality, teleportation, salvation through advanced technology, promotion out of a simulated reality, computational monadology, and the revision theory of resurrection.

A naturalistic theory of intentionality is proposed that differs from previous evolutionary and tracking theories. Full-blown intentionality is constructed through a series of evolvable refinements. A first, minimal version of intentionality originates from a conjectured internal process that estimates an organism’s own fitness and that continually modifies the organism. This process produces the directedness of intentionality. The internal estimator can be parsed into intentional components that point to components of the process that produces fitness. It is argued that (...) such intentional components can point to mistaken or non-existing entities. Different Fregian senses of the same reference correspond to different components that have different roles in the estimator. Intentional components that point to intentional components in other organisms produce directedness towards semi-abstract entities. Finally, adding a general, population-wide means of communication enables intentional components that point to fully abstract entities. Intentionality thus naturalized has all of its expected properties: being directed; potentially making errors; possibly pointing to non-existent, abstract, or rigid entities; capable of pointing many-to-one and one-to-many; distinguishing sense and reference; having perspective and grain; and having determinate content. Several examples, such as ‘swampman’ and ‘brain-in-a-vat’, illustrate how the theory can be applied. (shrink)

This paper addresses Prinz's naturalistic theory of conceptual content, which he has defended in several works (Prinz, 2000; 2002; 2006). More precisely, I present in detail and critically assess his account of referential content, which he distinguishes from nominal or cognitive content. The paper argues that Prinz's theory faces four important difficulties, which might have significant consequences for his overall empiricist project.

Truth by convention, once thought to be the foundation of a uniquely promising approach to explaining our access to the truth in nonempirical domains, is nowadays widely considered an absurdity. Its fall from grace has been due largely to the influence of an argument that can be sketched as follows: our linguistic conventions have the power to make it the case that a sentence expresses a particular proposition, but they can’t by themselves generate truth; whether a given proposition is true—and (...) so whether the sentence that expresses it is true—is a matter of what the world is like, which means it isn’t a matter of convention alone. The consensus is that this argument is decisive against truth by convention. Strikingly, though, it has rarely been formulated with much precision. Here I provide a new rendering of the argument, one that reveals its structure and makes transparent just what assumptions it requires, and then I assess conventionalists’ prospects for resisting each of those assumptions. I conclude that the consensus is mistaken: contrary to what is almost universally thought, there remains a promising way forward for the conventionalist project. Along the way, I clarify conventionalists’ commitments by thinking about what truth by convention would need to be like in order for conventionalism to do the epistemological work it’s intended to do.

The Vienna Circle was a group of scientifically-minded philosophers, many physicists by training, who in the 1920s and 30s developed the cluster of philosophical doctrines known as Logical Positivism. Among the Circle’s most distinguished members were Rudolf Carnap and Herbert Feigl, each of whom emigrated to America during the Nazi era. It is said that Feigl, the author of an important 1958 monograph defending a materialist approach to the mind-body problem, once gave a visiting lecture on the problem of consciousness (...) at UCLA, where Carnap was teaching. Feigl argued that although there were good reasons for believing that the mind is fundamentally physical, the physical explanation of the ‘qualia’ of sensory experience – the ineffable sensory qualities involved in, say, smelling coffee – was still a mystery to science. Now the story becomes apocryphal. Carnap is supposed to have interrupted, ‘But Feigl, there is something missing from your lecture. Science is beginning to explain qualia in terms of the alpha factor!’. We can imagine Feigl somewhat alarmed by this interjection from the great Carnap: ‘But Carnap, please tell me: what is the alpha factor?’. ‘Well, Feigl’ Carnap replied ‘if you tell me what qualia are, I’ll tell you what the alpha factor is’.

In this paper, we take a meta-theoretical stance and aim to compare and assess two conceptual frameworks that endeavor to explain phenomenal experience. In particular, we compare Feinberg & Mallatt’s Neurobiological Naturalism (NN) and Tononi’s and colleagues' Integrated Information Theory (IIT), given that the former pointed out some similarities between the two theories (Feinberg & Mallatt 2016c-d). To probe their similarity, we first give a general introduction to both frameworks. Next, we expound a ground plan for carrying out our (...) analysis. We move on to articulate a philosophical profile of NN and IIT, addressing their ontological commitments and epistemological foundations. Finally, we compare the two point-by-point, also discussing how they stand on the issue of artificial consciousness. (shrink)

On one standard philosophical position adopted by evolutionary naturalists, human ethical systems are nothing more than evolutionary adaptations that facilitate social behavior. Belief in an absolute moral foundation is therefore in error. But evolutionary naturalism, by its commitment to the basic valutional concept of fitness, reveals another, logical error: standard conceptions of value in terms of simple predication and properties are mistaken. Valuation has instead, a relational structure that makes reference to respects, subjects and environments. This relational nature is illustrated (...) by the analogy commonly drawn between value and color. Color perception, as recognized by the ecological concept, is relational and dependent on subject and environment. In a similar way, value is relational and dependent on subject and environment. This makes value subjective, but also objective in that it is grounded on facts about mattering. At bottom, values are complex relational facts. The view presented here, unlike other prominent relational and naturalistic conceptions of value, recognizes the full range of valuation in nature. The advantages of this relational conception are first, that it gets valuation right; second, it provides a framework to better explain and understand valuation in all its varieties and patterns.

The paper distinguishes three strategies by means of which empirical discoveries about the nature of morality can be used to undermine moral judgements. On the first strategy, moral judgements are shown to be unjustified in virtue of being shown to rest on ignorance or false belief. On the second strategy, moral judgements are shown to be false by being shown to entail claims inconsistent with the relevant empirical discoveries. On the third strategy, moral judgements are shown to be false in (...) virtue of being shown to be unjustified; truth having been defined epistemologically in terms of justification. By interpreting three recent error theoretical arguments in light of these strategies, the paper evaluates the epistemological and metaphysical relevance of empirical discoveries about morality as a naturally evolved phenomenon.

This paper examines recent feminist work on Spinoza and identifies the elements of Spinoza’s philosophy that have been seen as promising for feminist naturalism. I argue that the elements of Spinoza’s work that feminist theorists have found so promising are precisely those concepts he derives from Hobbes. I argue that the misunderstanding of Hobbes as architect of the egoist model of human nature has effaced his contribution to Spinoza’s more praised conception of the human individual. Despite misconceptions, I argue that (...) the model of human nature, the view on human emotions and the conception of individual power that Hobbes created and Spinoza developed is an uncommonly useful one for feminist political theory. Through reexamining Hobbes’ model of human nature and the emotions I will argue that Hobbes’ theory of the internal weighing of emotions provides an important mechanism for understanding how the individuals’ affects can be reformed. I will show how we can use this naturalistic model of the human individual to answer contemporary theoretical and practical questions of how to empower women and how to effectively identify, challenge and change social categories, norms and institutions which are disempowering. In particular, I will argue that feminist projects of empowerment need a way to measure empowerment and a way to understand how to understand the power of harmful norms and customs. Understanding the way certain norms and practices disempower women while forming their affects and self‐conceptions provides the first step to reform of these practices. Spinoza and Hobbes provide us with a further tool to reform, and that is their understanding of the role of emotions in human action and power, and the need to reform and reorganize the emotions of individuals in order to escape harmful patterns of behavior.

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)

The chapter distinguishes between a weak and a strong form of ontological naturalism. Strong ontological naturalism is the view that all truths can be deduced, at least in principle, from truths about physical entities at the lowest level of organization, for example, truths about the elementary particles and forces. Weak ontological naturalism is the view that only physical properties can be causally efficacious. Strong ontological naturalism entails weak ontological naturalism but not vice versa. I then argue that the existence of (...) a truth property is consistent with weak ontological naturalism, as truth is not causally efficacious. After considering several prominent theories of truth, I argue that the only theories of truth that are consistent with strong ontological naturalism are deflationary doctrines that deny that there is a substantial truth property but these theories are not suitable adjoints to strong naturalism, as folks with strong naturalist inclinations normally want to posit the existence of substantial natural properties. Yet if the truth property itself is insubstantial, so are claims about the existence of substantial natural properties. I conclude by arguing that the result that there cannot be a naturalistic theory of truth is unsurprising, as there are independent reasons for thinking that the basic semantic notions must be treated an irreducible, primitive properties.

By bringing together Dretske’s theory of knowledge, Shannon’s theory of information, and the conceptual framework of statistical physics, this paper explores some of the meta-physical challenges posed by a naturalistic notion of semantical information. It is argued that Dretske’s theory cannot be said to be naturalistically grounded in the world described by classical physics and that Dretske information is not consistent with Shannon information. A possible route to reconciling Dretske’s insights with Shannon’s theory is proposed. Along the way, an (...) attempt is made to clarify several points of possible confusion about the relationships between Dretske information, Shannon information and statistical physics. (shrink)

Alvin Plantinga and Phillip E. Johnson strongly attack "metaphysical naturalism", a doctrine based, in part, on Darwinian concepts. They claim that this doctrine dominates American academic, educational, and legal thought, and that it is both erroneous and pernicious. Stuart Kauffman claims that currently accepted versions of Darwinian evolutionary theory are radically incomplete, that they should be supplemented by explicit recognition of the importance of coherent structures — the prevalence of "order for free". Both of these developments are here interpreted in (...) relation to some contemporary theistic notions of "creation", including those of Lewis Ford, Robert Neville, and Robert Sokolowski. Kaufmann’s approach is consistent with the approach of process theism, and is not invalidated by the attacks of Plantinga and Johnson. (shrink)

Survey article on Naturalism dealing with Hume's NOFI (including Prior's objections), Moore's Naturalistic Fallacy and the Barren Tautology Argument. Naturalism, as I understand it, is a form of moral realism which rejects fundamental moral facts or properties. Thus it is opposed to both non-cognitivism, and and the error theory but also to non-naturalism. General conclusion: as of 1991: naturalism as a program has not been refuted though none of the extant versions look particularly promising.

This paper will investigate the basic question of the nature of perception, as theoretically approached from a purely naturalistic standpoint. An adequate theory must not only have clear application to a world full of pre-existing biological examples of perception of all kinds, from unicellular perception to conscious human perception, but it must also satisfy a series of theoretical or philosophical constraints, as enumerated and discussed in Section 1 below. A perceptual theory invoking _reflexive dispositions_--that is, dispositions directed toward the (...) very same worldly perceived objects or properties that caused them--will be defended as one legitimate such naturalistic theory.

Two opposed movements of thought threaten philosophy as an autonomous practice from the inside: scientific naturalism and quietism. Naturalism (qua methodological thesis) threatens to turn philosophy into a mere ancilla of the sciences, quietism understood as the prescription to remain silent in philosophy would not countenance any more "positive" philosophy. This book reconstructs naturalism and quietism such that it becomes clear naturalism does have the potential to end philosophy as an autonomous practice and that quietism, correctly understood, does not. To (...) this end, this book provides arguments against the prevailing orthodox status of naturalism and a heterogenous reading of Wittgenstein's metaphilosophical quietism as the rejection of a certain kind of theories in philosophy, namely quasi-scientific theories.

Metaethical realists disagree about the nature of normative properties. Naturalists think that they are ordinary natural properties: causally efficacious, a posteriori knowable, and usable in the best explanations of natural and social sciences. Non-naturalist realists, in contrast, argue that they are sui generis: causally inert, a priori knowable and not a part of the subject matter of sciences. It has been assumed so far that naturalists can explain causally how the normative predicates manage to refer to normative properties, whereas non-naturalists (...) are unable to provide equally satisfactory metasemantic explanations. This article first describes how the previous non-naturalist accounts of reference fail to tell us how the normative predicates could have come to refer to the non-natural properties rather than to the natural ones. I will then use the so-called qua-problem to show how the causal theories of reference of naturalists also fail to fix the reference of normative predicates to unique natural properties. Finally, I will suggest that, just as naturalists need to rely on the non-causal mechanism of reference magnetism to solve the previous problem, non-naturalists, too, can rely on the very same idea to respond to the pressing metasemantic challenges that they face concerning reference.

Some materialists believe that physics is rich enough to bridge Levine's Explanatory Gap1, while others believe that it is not. Here I promote an intermediate position holding that physics is rich enough to explain why this gap seems more intractable than similar inter-theoretic explanatory gaps, without providing a full-blown “physical” explanation of consciousness. At a minimum, such an approach needs to explore the prospects of empirical discoveries that can diminish the power of anti-physicalist arguments like Chalmers's “conceivability argument”2 and Jackson's (...) “knowledge argument.” While this is not an easy task, recent advances in the physics of spacetime and information convince us that these prospects are not poor. The empirical bent of this approach suggests framing it as a naturalist theory of mind seeking to situate or make room for consciousness within our great naturalist system, but the reliance of this approach on recent (re)conceptions of time and information pulls the carpet out from under essential concepts like concreteness and causation, thus demanding a radically reconfigured naturalism, or neo-naturalism. The question that will frame this discussion is, “What could possibly count as an empirical fact that can help naturalize consciousness?”. (shrink)

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)

Many philosophers these days consider themselves naturalists, but it's doubtful any two of them intend the same position by the term. In Second Philosophy, Penelope Maddy describes and practices a particularly austere form of naturalism called "Second Philosophy". Without a definitive criterion for what counts as "science" and what doesn't, Second Philosophy can't be specified directly ("trust only the methods of science" for example), so Maddy proceeds instead by illustrating the behaviors of an idealized inquirer she calls the "Second Philosopher". (...) mhis Second Philosopher begins from perceptual common sense experimentation, theory formation and testing, working all the while to asses, correct and improve her methods as she goes. Second Philosophy is then the result of the Second Philosopher's investigations. Maddy delineates the Second Philosopher's approach by tracing her reactions to various familiar skeptical and transcendental views (Descartes, Kant, Carnap, late Putnam, van Fraassen), comparing her methods to those of other self-described naturalists (especially Quine), and examining a prominent contemporary debate (between disquotationalists and correspondence theorists in the theory of truth) to extract a properly second-philosophical line of thought. She then undertakes to practice Second Philosophy in her reflections on the ground of logical truth, the methodology, ontology and epistemology of mathematics, and the general prospects for metaphysics naturalized.

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)

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)

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.

In Beyond Good and Evil, Nietzsche demands that “psychology shall be<br>recognized again as the queen of the sciences.” While one might cast a dubious glance at the “again,” many of Nietzsche’s insights were indeed psychological, and many of his arguments invoke psychological premises. In Genealogy, he criticizes the “English psychologists” for the “inherent psychological absurdity” of their theory of the origin of good and bad, pointing out the implausibility of the claim that the utility of unegoistic<br>actions would be forgotten. Tabling (...) whether this criticism is valid, we see Nietzsche’s methodological naturalism here: moral claims should be grounded in empirical psychological claims. Later in Genealogy, Nietzsche advances his own naturalistic account of the origins of good, bad, and evil.<br>Three cheers for methodological naturalism, but it was not Nietzsche’s innovation, and he did not pioneer its application to morality. The list of moral naturalists who appealed to psychology arguably includes Aristotle, Descartes, Spinoza, Bentham, and Mill, among many others. If Nietzsche’s naturalism is to be worth the candle of contemporary scholarship, it must involve more than the methodological naturalism that predated him by centuries and to which he made no serious contribution. Nietzsche’s key contribution to naturalism is not his adherence to its methodology, but his discovery of certain psychological facts. In particular, he realized that mental states are not ordinary dyadic relations between a subject and an intentional content. Nietzsche discovered the tenacity of intentional states: when an intentional state loses its object (because the subject realizes the object does not exist, because the object is forbidden, or because of something else), a new object replaces the original; the state does not disappear entirely. As Nietzsche puts it Genealogy, “Man would rather will the void than be void of will.” Nietzsche relies on the tenacity thesis in his explanation of the origin of bad conscience: “All instincts that do not discharge themselves outwardly turn inward […. They turn] against [their] possessors.” When hostility towards others becomes impossible, hostility does not disappear; instead, its object is replaced. (shrink)

Perhaps the most familiar understanding of “naturalism” derives from Quine, understanding it as a continuity of empirical theories of the world as described through the scientific method. So, it might be surprising that one of the most important naturalistic moral realists, Philippa Foot, rejects standard evolutionary biology in her justly lauded _Natural Goodness_. One of her main reasons for this is the true claim that humans can flourish (eudaimonia) without reproducing, which she claims cannot be squared with evolutionary (...) theory and biology more generally. The present argument concludes that Foot was wrong to reject evolutionary theory as the empirical foundation of naturalized eudaimonist moral realism. This is based on contemporary discussion of _biological function_ and _evolutionary fitness_, from which a definition of “eudaimonia” is constructed. This gives eudaimonist moral realism an empirically respectable foundation. (shrink)

We argue, contra Joshua Knobe in a companion chapter, that most people have an understanding of free will and responsible agency that is compatible with a naturalistic vision of the human mind. Our argument is supported by results from a new experimental philosophy study showing that most people think free will is consistent with complete and perfect prediction of decisions and actions based on prior activity in the brain (a scenario adapted from Sam Harris who predicts most people will (...) find it inconsistent with free will). We explain why most people are "theory-lite" about the nature of mind and free will--they are not committed to substantive theories of the underlying causal structure of mind, such as Knobe's "transcendence vision". Rather, we suggest a "causal competition principle"--that an agent's actions will be deemed unfree when they are perceived to be fully caused by factors that do not include her reasons. This principle explains why people, including some scientists, perceive neuroscientific explanations as threatening free will when they are described in terms of neural processes fully causing actions to the exclusion of agents' reasons or reasoning processes.

This chapter examines the influence of the empirical sciences (e.g., physics, biology, psychology) in contemporary analytic philosophy, with focus on philosophical theories that are guided by findings from the empirical sciences. Scientific approaches to philosophy follow a tradition of philosophical naturalism associated with Quine, which strives to ally philosophical methods and theories more closely with the empirical sciences and away from a priori theorizing and conceptual analysis.

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.

The prescriptive force of methodological rules rests, I argue, on the acceptance of scientific theories; that of the most general methodological rules rests on theories in the philosophy of science, which differ from theories in the several sciences only in generality and abstraction. I illustrate these claims by reference to methodological disputes in social science and among philosophers of science. My conclusions substantiate those of Laudan except that I argue for the existence of transtheoretical goals common to (...) all scientists and concrete enough actually to have bearing on methodology. And I argue that Laudan is committed to such goals himself, willy nilly. (shrink)

The basic assumption present in these articles is that naturalism is highly compatible with a wide range of relevant philosophical questions and that, regardless of the classical problems faced by the naturalist, the price paid in endorsing naturalism is lower than that paid by essentialist or supernaturalist theories. Yet, the reader will find a variety of approaches, from naturalism in Moral Philosophy and Epistemology to naturalism in the Philosophy of Language, Philosophy of Mind and of the Aesthetics.

There is a worry about the intellectual legitimacy of philosophy. Although the sciences have a progressive history, with later theories largely building on earlier ones, and a tremendous amount of agreement within the scientific community about the approximate truth of current theory, philosophy is different. We do not see a progressive history of philosophical theorizing, and there is little agreement within the philosophical community about which theories are even roughly correct. This not only encourages a certain skepticism about (...) the possibility of philosophical knowledge, but a real question about whether the activity of philosophical theorizing is intellectually legitimate. It is argued here that there are features of a naturalistic methodology in philosophy which have the resources to respond to these concerns. (shrink)

In a recent exchange, John Worrall and Larry Laudan have debated the merits of the model of rational scientific change proposed by Laudan in his book Science and Values. On the model advocated by Laudan, rational change may take place at the level of scientific theory and methodology, as well as at the level of the epistemic aims of science. Moreover, the rationality of a change which occurs at any one of these three levels may be dependent on considerations at (...) the remaining levels. Yet, in spite of the avowedly anti-relativistic motivation of Laudan's model, Worrall criticizes Laudan for irrevocably relativizing scientific rationality to historically variant methodological standards.

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)

For the political naturalist, skepticism about political obligations only arises because of a basic confusion about the necessity of the state for human well-being. From this perspective, human beings are naturally political animals and cannot flourish outside of political relationships. In this paper, I suggest that this idea can be developed in two basic ways. For the thick naturalist, political institutions are constitutive of the best life. For the thin naturalist, they secure the basic background conditions of peace and stability (...) that are necessary for any minimally decent human life. Both approaches, however, are problematic, and while political institutions might have a special kind of value for human well-being, it is difficult to convert this claim into a justification for political obligations.

The paper concentrates on how the acceptance of radical naturalism in Quine’s theory of meaning escorts Quine to ponder the naturalized epistemology. W.V. Quine was fascinated by the evidential acquisition of scientific knowledge, and language as a vehicle of knowledge plays a significant role in his regimented naturalistic theory anchored in the scientific framework. My point is that there is an interesting shift from epistemology to language (semantic externalism). The rejection of the mentalist approach on meaning vindicates external that (...) somehow pave the way for ‘semantic holism’, a thesis where the meaning of a sentence is defined in turns to the totality of nodes and paths of its semantic networks where the meaning of linguistic units depend upon the meaning of the entire language. I would like to relook on Quine’s heart-throbbing claim about the co-extensiveness of the sentential relation and the evidential relation that point towards an affirmation of meaning holism and semantic externalism. Besides, the knowledge of acquaintance that relinquishes the singular thought from the account of psychological consideration and self-knowledge hypothesis copes up with the testimonial and warrant knowledge entangling by the claims of social knowledge as anticipated by Alvin Goldman. My conclusion would be nearer to the stance of semantic externalism inculcated by the social knowledge (in an epistemic sense) and semantic holism. (shrink)

In this paper, I show how realist moral naturalists can provide an intra-theoretic explanation of the epistemic possibility of wholesale moral error. This is a requirement on metaethical theories that has been recently defended by Akhlaghi (2021). After clarifying Akhlaghi’s argument and responding to Evers’s (2021) recent rebuttal, I argue that even under the assumption that moral facts are grounded in an appropriate subset of natural facts (N-facts), there is still a non-zero probability of wholesale moral error. This is (...) demonstrated by considering three types of epistemically possible scenarios: specifically, it could either be that N-facts do not actually exist, or that N-facts exist in a way that entails wholesale moral error, or that N-facts exist in a non-error theoretic way, but their existence is temporally restricted.

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)

Vetter (2015) develops a localised theory of modality, based on potentialities of actual objects. Two factors play a key role in its appeal: its commitment to Hardcore Actualism, and to Naturalism. Vetter’s commitment to Naturalism is in part manifested in her adoption of Aristotelian universals. In this paper, we argue that a puzzle concerning the identity of unmanifested potentialities cannot be solved with an Aristotelian conception of properties. After introducing the puzzle, we examine Vetter’s attempt at amending the Aristotelian conception (...) in a way that avoids the puzzle, and conclude that this amended version is no longer to be considered naturalistic. Potentiality theory cannot be both actualist and naturalist. We then argue that, if naturalism is to be abandoned by the actualist, there are good reasons to adopt a Platonist conception of universals, for they offer a number of theoretical advantages and allow us to avoid some of the problems facing Vetter’s theory.

Bernard Williams’ “Nietzsche’s Minimalist Moral Psychology”, replete with provocative and insightful claims, has been extremely influential in Nietzsche scholarship. In the two decades since its publication, much of the most interesting and philosophically sophisticated work on Nietzsche has focused on exactly the topics that Williams addresses: Nietzsche’s moral psychology, his account of action, his naturalistic commitments, and the way in which these topics interact with his critique of traditional morality. While Williams’ pronouncements on these topics are brief and at (...) times oracular, and although many important details are not addressed, he manages to identify some of the richest veins in Nietzsche’s texts. In this response, I focus on the four central claims in Williams’ article. Sections One and Two address the claim that Nietzsche is a naturalist and an advocate of “minimalist moral psychology,” respectively. Sections Three and Four examine Williams’ interpretations of Nietzsche on the will and agency. Finally, Section Five critiques Williams’ claim that Nietzsche cannot be a source of philosophical theories. (shrink)

There are two chief tasks which confront the philosophy of scientific method. The first task is to specify the methodology which serves as the objective ground for scientific theory appraisal and acceptance. The second task is to explain how application of this methodology leads to advance toward the aim(s) of science. In other words, the goal of the theory of method is to provide an integrated explanation of both rational scientific theory choice and scientific progress.

Naturalism in philosophy has a long time and rich heritage. In the second half of twentieth century, there have been a number of philosophers who called for naturalizing epistemology. In recent years the movement to naturalize epistemology has become increasingly popular. The interest in naturalistic epistemology traces to W.V.Quine’s paper "Epistemology Naturalized" (1969). In this paper, Quine argued for a new approach to epistemological questions, and he made argument for transforming epistemology into a new discipline by making it a (...) part of natural science. According to Quine, Descartes’s view of epistemology as first philosophy was doomed to failure, because it was pursued outside science. Epistemology, as traditionally practiced, is a normative enterprise. It seeks the standards which might be used to justify our beliefs and judgments. Traditional rationalists and empiricists do agree that search of these standards within natural science would be illegitimate; because the object of traditional epistemology is to provide a ground for natural science. But naturalists reject the autonomy of epistemology, and seek continuity between epistemology and natural science. Quine says that I see philosophy not as a priori groundwork for science, but as continuous with science. This paper seeks to achieve the following aims: (1) Determining the different concepts which fall under the heading of naturalistic epistemology. (2) Clarify the arguments provided by naturalistic epistemologists to confirm their theories. (3) Discussing the most important criticisms advanced by philosophers against naturalistic epistemology. (4) Stating our attitude toward naturalistic epistemology through defending the "moderate epistemic naturalism". Since strong naturalistic epistemology, in affirmative usage, amounts to scientism, this paper seeks to answer a general question about the legitimacy of scientism. (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.

In this paper I discuss five meta-ethical challenges to Naturalistic Moral Realism, which includes secular moral codes such as Secular Humanism that, in my view, naturalists need to address to keep their commitment to moral realism from looking like special pleading. The five challenges are as follows: 1. The Ontological Problem (OP): How do such moral principles exist? 2. The Epistemic Problem (EP): How does our moral sense/intuition track such principles? 3. The Influence Problem (IP): What authority does the (...) existence of such principles have to supervene on our behavior? 4. The Axiological Problem (AP): What entities have moral value and deserve moral consideration? 5. Methodological Problem (MP): How do we go about arbitrating between moral claims when they conflict?

In this paper, I argue that a naturalist approach in philosophy of mathematics justifies a pluralist conception of set theory. For the pluralist, there is not a Single Universe, but there is rather a Multiverse, composed by a plurality of universes generated by various set theories. In order to justify a pluralistic approach to sets, I apply the two naturalistic principles developed by Penelope Maddy (cfr. Maddy (1997)), UNIFY and MAXIMIZE, and analyze through them the potential of the (...) set theoretic multiverse to be the best framework for mathematical practice. According to UNIFY, an adequate set theory should be foundational, in the sense that it should allow one to represent all the currently accepted mathematical theories. As for MAXIMIZE, this states that any adequate set theory should be as powerful as possible, allowing one to prove as many results and isomorphisms as possible. In a recent paper, Maddy (2017) has argued that this two principle justify ZFC as the best framework for mathematical practice. I argue that, pace Maddy, these two principles justify a multiverse conception of set theory, more precisely, the generic multiverse with a core (GMH). (shrink)

The aim of this paper is to document Laudan's rejection of the appeal to intuition in the context of his development of normative naturalism. At one point in the development of his methodological thinking, Laudan appealed to pre-analytic intuitions, which might be employed to identify episodes in the history of science against which theories of scientific methodology are to be tested. However, Laudan came to reject this appeal to intuitions, and rejected this entire approach to the evaluation of a (...) theory of method. This is an important stage in the development of his normative naturalist meta-methodology. (shrink)

In this chapter I seek to examine the credibility of Finnis’s basic stance on Aquinas that while many neo-Thomists are meta-ethically naturalistic in their understanding of natural law theory (for example, Heinrich Rommen, Henry Veatch, Ralph McInerny, Russell Hittinger, Benedict Ashley and Anthony Lisska), Aquinas’s own meta-ethical framework avoids the “pitfall” of naturalism. On examination, the short of it is that I find Finnis’s account (while adroit) wanting in the interpretation stakes vis-à-vis other accounts of Aquinas’s meta-ethical foundationalism. I (...) think that the neo-Thomists are basically right to argue that for Aquinas we cannot really understand objective truths about moral standards unless we derive them from our intellective knowledge of natural facts as given to us by the essential human nature that we have. While I find Finnis’s interpretative position on Aquinas wanting, I go on to argue that his own attachment to non-naturalism is justified and should not be jettisoned. Because I think non-naturalism important to the future tenability of a viable natural law ethics (an ethics that is both cognitive and objectivist), I argue that Finnis should, so to speak, “beef up” his “fundamental option” for non-naturalism and more fully avail himself of certain argumentative strategies available in its defense, argumentative strategies that are inspired by the analytical philosophy of G.E. Moore. (shrink)

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.

What are the conditions on a successful naturalistic account of moral properties? In this paper I discuss one such condition: the possibility of moral concepts playing a role in good empirical theories on a par with those of the natural and social sciences. I argue that Peter Railton’s influential account of moral rightness fails to meet this condition, and thus is only viable in the hands of a naturalist who doesn’t insist on it. This conclusion generalises to all (...) versions of naturalism that give a significant role to a dispositional characterisation of moral properties. I also argue, however, that the epistemological and semantic motivations behind naturalism are consistent with a version of naturalism that doesn’t insist on the explanatory condition. The conclusion is that those naturalists who are attracted to accounts of moral properties such as Railton’s would do better not to insist on this\break condition. (shrink)

Non-naturalism is the view that normative properties are response-independent, irreducible to natural properties, and causally inefficacious. An underexplored question for non-naturalism concerns the metasemantics of normative terms. Ideally, the non-naturalist could remain ecumenical, but it appears they cannot. Call this challenge the metasemantic challenge. This chapter suggests that non-naturalists endorse an epistemic account of reference determination of the sort recently defended by Imogen Dickie, with some modifications. An important implication of this account is that, if correct, a fully fleshed out (...) moral epistemology will simultaneously rebut metasemantic objections to non-naturalism. Thus, both the metasemantic and the more widely discussed epistemological challenges in effect amount to one. Before setting out the positive view, the chapter considers why all of the traditional metasemantic theories cause trouble for the non-naturalist. This includes discussions of teleosemantics, conceptual role semantics, as well as Schroeter and Schroeter’s “connectedness” model. (shrink)

Moral realism and ethical naturalism are both highly attractive ethical positions but historically they have often been thought to be irreconcilable. Since the late 1980s defenders of Cornell Realism have argued that the two positions can consistently be combined. They make three constitutive claims: (i) Moral properties are natural kind properties that (ii) are identical to (or supervene) on descriptive functional properties, which (iii) causally regulate our use of moral terms. We offer new arguments against the feasibility of Cornell realism (...) and then show that there is a way to be a naturalistic realist that avoids internal inconsistency and uniquely provides for moral normativity.
