This paper raises objections to Alvin Plantinga's evolutionary argument against naturalism.

In "Warrant and Proper Function" Plantinga argues that atheistic Naturalism is self-defeating. What is the probability that our cognitive faculties are reliable, given this Naturalism and an evolutionary explanation of their origins? Plantinga argues that if the Naturalist is modest enough to believe that it is irrational to have any belief as to the value of this probability, then he is irrational even to believe his own Naturalism. I suggest that Plantinga's argument has a false premise, and that even if (...) his argument were sound there would be reasons for doubting whether the Naturalist should respond to it by abandoning his Naturalism.

In this paper, I shall try to present and defend some arguments against naturalistic evolutionism that are partly inspired by A. Plantinga’s well-known evolutionary argument against naturalism. I give two different characterizations of naturalistic evolutionism: according to the first, it is the view for which, for every human activity, that activity is governed by adaptive functions and nothing else ; according to second, it is the view for which, for most human activities, those activities are governed by adaptive functions and (...) nothing else. Both versions of naturalistic evolutionism fall in trouble when they have to ground the truth of metaphysical beliefs, even including the beliefs that N.E.1, that N.E.2, that N.E.1 is true and that N.E.2 is true. Thus, it seems either that naturalistic evolutionism is false and self-defeating or that its defense is a huge metaphysical task to undertake than one could expect. (shrink)

Alvin Plantinga argues that our cognitive mechanisms have been selected for their ability to sustain reproductively successful behaviors, not for their ability to track truth. This aspect of our cognitive mechanisms is said to pose a problem for the biological theory of evolution by natural selection in the following way. If our cognitive mechanisms do not provide any assurances that the theories generated by them are true, then the fact that evolutionary theory has been generated by them, and even accepted (...) by them, provides no assurance whatever that evolutionary theory is true. Plantinga’s argument, I argue, innocently assumes that the (problematic) “truth-tracking character” of our native cognitive mechanisms is the only possible or available source of rational warrant or justification for evolutionary theory. But it isn’t. Plantinga is ignoring the artificial mechanisms for theorycreation and theory-evaluation embodied in the complex institutions andprocedures of modern science. (shrink)

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

The Self-Defeating Character of Skepticism [ABSTRACT] Douglas C. Long Philosophical skepticism arises from a Cartesian first-person perspective that initially rejects as unjustified any appeal to sense perception. I argue that, contrary to the cogito argument, when a “purely subjective” epistemology cuts one off from justified beliefs about the world in this way, it undermines justified belief about one’s own existence as an individual in the world as well. Therefore, philosophical doubt expressed in the form: “I know that I exist but (...) I cannot know about the existence of anything else,” is in fact self-defeating. Philosophers have mistakenly assumed that the subjective epistemological perspective from which philosophical doubt about the existence of material objects is expressed is indeed our ordinary first person perspective on ourselves. And we of course know that the latter perspective surely provides epistemological access to ourselves as existing active subjects of experience. However, I claim that traditional wholesale epistemological skepticism in fact attempts to mandate an importantly different perspective on ourselves that we do not and cannot have. The feature of skepticism which I believe renders it vulnerable is the assumption that each of us has a right to be certain of his own existence as a subject of conscious experience even in the face of comprehensive doubt about our empirical beliefs.

Throughout philosophical history, there has been a recurring argument to the effect that determinism, naturalism, or both are self-referentially incoherent. By accepting determinism or naturalism, one allegedly acquires a reason to reject determinism or naturalism. _The Epistemological Skyhook_ brings together, for the first time, the principal expressions of this argument, focusing primarily on the last 150 years. This book addresses the versions of this argument as presented by Arthur Lovejoy, A.E. Taylor, Kurt Gödel, C.S. Lewis, Norman Malcolm, Karl Popper, J.R. (...) Lucas, William Hasker, Thomas Nagel, Alvin Plantinga, and others, along with the objections presented by their many detractors. It concludes by presenting a new version of the argument that synthesizes the best aspects of the others while also rendering the argument immune to some of the most significant objections made to it.

An important source of doubt about our knowledge of the "external world" is the thought that all of our sensory experience could be delusive without our realizing it. Such wholesale questioning of the deliverances of all forms of perception seems to leave no resources for successfully justifying our belief in the existence of an objective world beyond our subjective experiences. I argue that there is there is a fatal flaw in the very expression of philosophical doubt about the "external world." (...) Therefore, no such justification is necessary. The feature of skepticism which I believe renders it vulnerable is the assumption that each of us has a right to be certain of his own existence as a subject of conscious experience even in the face of comprehensive doubt about our empirical beliefs.

In the intriguing final chapter of his book Warrant and Proper Function, Alvin Plantinga argues that naturalism, conjoined with a neo-Darwinian picture, is self-defeating. This argument has drawn its fair share of critical response. Plantinga in turn has recently responded in his as yet unpublished manuscript ‘Naturalism Defeated’. This first volley of debate has helped bring into focus several points of contention between Plantinga and his critics, but to date, the logical structure of the argument has not been an element (...) of the discussion. In this paper I argue that the logical structure of Plantinga’s argument has been misconstrued – that it does not show that naturalism is self-defeating. I argue further that properly reconstructed, it fails to make the case for the (ordinary) defeat of naturalism as well. (shrink)

In this essay, I consider an evolutionary debunking argument (EDA) that purports to undermine the epistemic justification of the belief in the reliability of our belief-forming processes, and an evolutionary vindicating argument (EVA) that seeks to establish that such a belief is epistemically justified. Whereas the EDA in question seems to fall prey to crippling self-defeat, the EVA under consideration seems to fall prey to vicious circularity. My interest in those arguments and the problems they face lies in what they (...) might tell us about the possibly aporetic nature of reason. For, if we take the EDA and the EVA in question to consist of true or plausible premises and valid inferences at which we arrive through a meticulous use of reason, then their falling victim to either crippling self-defeat or vicious circularity might be regarded as a sign that, when we push rational reflection on the reliability, or lack thereof, of our belief-forming capacities to the limit, we end up in a situation of aporia from which there seems to be no escape.

Are Hume's skeptical principles reconcilable with his naturalistic 'science of man'? This is the 'riddle' of Hume's Treatise. Without a solution to this riddle (specifically, one that offers an affirmative answer to the question), Hume's project seems self-defeating, with his skeptical principles undermining his attempt to develop the new 'science' (pp. 3, 270ff; cf. p. vii). Thus, the riddle has understandably been both a major point of contention among Hume scholars as well as a source of intriguing and helpful discussions (...) for philosophers interested in Hume's work. Paul Russell attempts to solve the riddle by fundamentally reorienting the way that people read the Treatise (see, e.g., pp. 61, 69, 270-2)..... All things considered, Paul Russell's The Riddle of Hume's Treatise is an excellent and thought-provoking text that is a pleasure to read. It provides a compelling case regarding the nature and significance of Hume's 'irreligious' motives. In so doing, it lends further support for a naturalistic reading of Hume, according to which Hume's skepticism serves his naturalism and, ultimately, his 'anti-Christian' motives. It deserves to have an important impact not only on Hume research, but on the narrative that drives undergraduate survey courses in the history of early modern philosophy as well. (shrink)

Global meta-philosophical skepticism (i.e. completely unrestricted skepticism about philosophy) based upon disagreement faces the problem of self-defeat since it undercuts its motivating conciliatory principle. However, the skeptic may easily escape this threat by adopting a more modest kind of skepticism, that will be called “extensive meta-philosophical skepticism”, i.e., the view that most of our philosophical beliefs are unjustified, except our beliefs in epistemically fundamental principles. As I will argue in this paper, this kind of skepticism is well-motivated, does not undercut (...) the conciliatory principle, but still poses a radical challenge to philosophy as a cognitive discipline. Moreover, I will argue that non-global skepticism that is still extensive undermines itself as well. The deeper reason for this is that this more modest kind of skepticism can only be motivated by the assumption that disagreement with philosophical peers is abundant and that we can identify peers only by relying on track-record arguments. But then one can argue for extensive meta-philosophical skepticism only if one presupposes that those philosophical beliefs that form the basis of track-record evaluations are justified. Here, the threat of self-defeat looms again. I will proceed by first defending the premises of this new anti-skeptical argument against standard objections from the literature. Second, I will show in more detail where the epistemic inconsistency arises in the argument for extensive meta-philosophical skepticism. I conclude with an assessment of the scope and the limits of my argument. (shrink)

Jennifer Saul argues that the evidence from the literature on implicit biases entails a form of skepticism. In this paper, I argue that Saul faces a dilemma: her argument is either self-defeating, or it does not yield a skeptical conclusion. For Saul, both results are unacceptable; thus, her argument fails.

: Radical meta-normative skepticism is the view that no standard, norm, or principle has objective authority or normative force. It does not deny that there are norms, standards of correctness, and principles of various kinds that render it possible that we succeed or fail in measuring up to their prerogatives. Rather, it denies that any norm has the status of commanding with objective authority, of giving rise to normative reasons to take seriously and follow its demands. Two powerful transcendental arguments (...) challenge this view. First, skepticism is said to be self-defeating: Settling what to accept, and in particular whether to accept skepticism, appears to be a reason-guided enterprise. How can skeptics coherently support their view by citing reasons in their favor after they just rejected them throughout? Second, there is the practical-deliberative version, most recently developed by David Enoch: We are essentially deliberative creatures. Yet deliberation appears to require that there are correct answers in the form of normative reasons to our practical questions. Thus confidence in the sensible nature of deliberation should inspire confidence in reasons. The essay undermines both transcendental arguments by demonstrating, first, how to support skepticism without deserting its tenets, and, second, how to deliberate in skeptical fashion. (shrink)

For over 20 years, Alvin Plantinga has been advocating his Evolutionary Argument against Naturalism, or EAAN. We will argue that this argument functions as an atypical form of global skepticism, and Plantinga’s development of it has repercussions for other types of skepticism. First, we will go over the similarities and differences; for example, the standard ways of avoiding other forms of skepticism, namely by adopting some form of naturalized or externalist epistemology, do not work with the EAAN. Plantinga himself is (...) a naturalized epistemologist, and his skepticism comes from within this perspective. Next, we will look at how Plantinga moved from presenting his skepticism diachronically, as a loop, to presenting it synchronically, as an infinite regress. Finally, we can extend this move from Plantinga’s skepticism to other forms of global skepticism, in so far as these will involve the rejection of our cognitive faculties’ reliability, and formulate them synchronically as well. Global skepticism is often accused of instability, since it leads us to skepticism about all of our beliefs, including belief in the skeptical scenario itself. Yet formulating it as an infinite regress rather than a loop allows the skeptical charge to go forward. (shrink)

Cognitive scientist Donald Hoffman and others have recently advanced an evolutionary debunking argument aimed at our perceptual beliefs in ordinary objects, based on the Interface Theory of Perception. In contrast with most recent criticisms of Interface Theory, which have targeted its characterizations of perception and veridicality, I raise a broad dialectical problem for Hoffman’s debunking argument. I show that the argument is self-defeating, and that responding to this problem by appealing to Universal Darwinism leads to a fatal dilemma for the (...) view. (shrink)

Anti-naturalistic critics of Unity of Science have often tried to establish a fundamental difference between social and physical science on the grounds that research in the social field (unlike physical research) seems to interfere with the original situations so as to make accurate predictions impossible. A 'social' prediction may, e.g., itself influence the course of events so that the prediction proves false. H. A. Simon has dealt with such effects of predictions in a well-known article. Drawing on a mathematical theorem, (...) Brouwer's so-called fixed-point theorem, he claims to prove that reactions to published predictions can be accounted for so that appropriately adjusted predictions can avoid being self-destructive. The present article is an attempt to show that Simon's use of the Brouwer theorem is misplaced, and that his proof does not parry the anti-naturalistic argument. Indeed, the burden of his proof is not really of a mathematical, but, it is argued, of a 'protosociological' kind. In conclusion, the article points to the fundamental inadequacy of a frame of reference which makes the 'interference' or 'reaction' effects due to people's having access to social knowledge appear strange or eccentric: as some kind of marginal irregularity causing trouble in the philosophy of (social) science.

Plato seems to have claimed that epistemological relativism is self-defeating in two ways. As reformulated by Siegel: arguments for relativism must be advanced as either relativistically or non-relativistically sound. In either case they are dialectically ineffective for the relativist. Second, relativism is either relativistically or non-relativistically true. Either choice commits the relativist to major concessions to her opponent, or so the story goes. But the relativist can advance her arguments as non-relativistically sound, for the consumption of the non-relativist. Moreover, relativists (...) can claim that relativism is true not only for the relativist, but for her non-relativist opponent as well. Relativism is not self-defeating in either of these ways, for much the same reasons that skepticism is not self-defeating. But we cannot live as relativists, because relativism leads to epistemic paralysis, as the example of prediction shows. (shrink)

This chapter contains sections titled: Theism Alternatives to Theism Naturalism and Its Woes Conclusion.

Plantinga claims to give a person who is agnostic about the ultimate source of his cognitive faculties an undefeatable defeater for all his beliefs. This argument of Plantinga’s bears a family resemblance to his much better known argument for saying that naturalism is self-defeating, but it has a much more ambitious conclusion. In the present paper, I try to show both that Plantinga’s argument for this conclusion fails, and that even if an “origins agnostic” were to succumb to it, a (...) cure for his skepticism is ready at hand—one that does not involve believing in anything like God.

The theory of recognition arises within Hegel's confrontation with epistemological skepticism and aims at responding to the questions raised by modern skepticism concerning the accessibility of the external world, of other minds, and of one's own mind. This is possible to the extent that the theory of recognition is the guiding thread of a critique of the modern foundational theory of knowledge and, at the same time, the point of departure for an alternative approach. In this article I will dwell (...) on six stages of the evolution of Hegel's thought prior to the Phenomenology (1797-1806),stages shed great light on the direction taken by his argumentative strategy. Synthetically, the stages are as follows: 1. Hegel naturalizes the epistemological questions; 2. to do so he critiques foundationalism qua theory of empirical knowledge; 3. and qua theory of epistemic justification; 4. the critique of foundationalism is linked to a critique of the corresponding representationalistic theory of perception; 5. this, in turn, is linked to a critique of the monological theories of self-consciousness and to the development of a model of the rise of self-conscious knowing; 6. finally, Hegel synthesizes these epistemological views in a theory of knowledge qua recognition and in a metaphilosophical theory of philosophical rationality qua self-recognition: knowledge without foundation is thus the condition of possibility of philosophy’s self-justification.

Naturalism is the label for the thesis that the tools we should use in answering philosophical problems are the methods and findings of the mature sciences—from physics across to biology and increasingly neuroscience. It enables us to rule out answers to philosophical questions that are incompatible with scientific findings. It enables us to rule out epistemological pluralism—that the house of knowledge has many mansions, as well as skepticism about the reach of science. It bids us doubt that there are facts (...) about reality that science cannot grasp. It gives us confidence to assert that by now in the development of science, absence of evidence is prima facie good grounds for evidence of absence: this goes for God, and a great deal else.

Sub-Thesis 1: We should be contingent reliabilists to avoid the threat of an unacceptably strong content skeptical thesis posed by content externalism and the possibility of twin thoughts. The predominant strategy for resisting this threat has been to rely on the claim that introspective self-attributions are immune to brute error; but this claim is problematic from a naturalistic standpoint.

Alvin Plantinga has famously argued that the naturalist who accepts evolutionary theory has a defeater for all of her beliefs, including her belief in naturalism and evolution. Hence, he says, naturalism, when conjoined with evolution, is self defeating and cannot be rationally accepted. This is known as the evolutionary argument against naturalism (EAAN). However, Tyler Wunder (Religious Studies 51:391– 399, 2015) has recently shown that if the EAAN is framed in terms of objective probability and theism is assumed to be (...) non-contingent, then either theism is necessarily false or the EAAN is unsound. Neither option is attractive to the proponent of the EAAN. Perry Hendricks (Religious Studies 1–5, 2018) has responded to Wunder’s criticism, showing that the EAAN can be salvaged and, indeed, strengthened, by framing it in terms not of naturalism (N), but of a proposition that is entailed by N that is also consistent with theism. We will show that once Hendricks’ solution to Wunder’s objection is accepted, a puzzle ensues: if the EAAN provides the naturalist with a defeater for all of her beliefs, then an extension of it appears to provide God with a defeater for all of his beliefs. After bringing out this puzzle, we suggest several ways in which the proponent of the EAAN might solve it, but also show some potential weaknesses in these purported solutions. Whether the solutions to the puzzle that we consider ultimately succeed is unclear to us. (Translation: the authors disagree. One author thinks that the solutions (or,at least, some of them) that we consider do solve the puzzle while the other author does not.) However, it is clear to us that this is an issue that proponents of the EAAN need to address. (shrink)

This book explores the question of what it means to be a human being through sustained and original analyses of three important philosophical topics: relativism, skepticism, and naturalism in the social sciences. Kevin Cahill's approach involves an original employment of historical and ethnographic material that is both conceptual and empirical in order to address relevant philosophical issues. Specifically, while Cahill avoids interpretative debates, he develops an approach to philosophical critique based on Cora Diamond's and James Conant's work on the early (...) Wittgenstein. This makes possible the use of a concept of culture that avoids the dogmatism that not only typifies traditional metaphysics but also frequently mars arguments from ordinary language or phenomenology. This is especially crucial for the third part of the book, which involves a cultural-historical critique of the ontology of the self in Stanley Cavell's work on skepticism. In pursuing this strategy, the book also mounts a novel and timely defense of the interpretivist tradition in the philosophy of the social sciences. Towards a Philosophical Anthropology of Culture will be of interest to researchers working on the philosophy of the social sciences, Wittgenstein, and philosophical anthropology. (shrink)

Alvin Plantinga has famously argued that metaphysical naturalism is self-defeating, and cannot be rationally accepted. I distinguish between two different ways of understanding this argument, which I call the "probabilistic inference conception", and the "process characteristic conception". I argue that the former is what critics of the argument usually presuppose, whereas most critical responses fail when one assumes the latter conception. To illustrate this, I examine three standard objections to Plantinga's evolutionary argument against naturalism: the Perspiration Objection, the Tu Quoque (...) Objection, and the "Why Can't the Naturalist Just Add a Little Something?" Objection. I show that Plantinga's own responses to these objections fail, and propose counterexamples to his first two principles of defeat. I then go on to construct more adequate responses to these objections, using the distinctions I develop in the first part of the paper. (shrink)

Memory skepticism denies our memory beliefs could have any notable epistemic good. One route to memory skepticism is to challenge memory’s epistemic trustworthiness, that is, its functioning in a way necessary for it to provide epistemic justification. In this paper we develop and respond to this challenge. It could threaten memory in such a way that we altogether lack doxastic attitudes. If it threatens memory in this way, then the challenge is importantly self-defeating. If it does not threaten memory in (...) this way, then the challenge leaves a foundation for an inference to the best explanation response, one we articulate and support. (shrink)

Plantinga's Evolutionary Argument Against Naturalism aims to show that naturalism is, as he puts it, ‘incoherent or self defeating’. Plantinga supposes that, in the absence of any God-like being to guide the process, natural selection is unlikely to favour true belief. Plantinga overlooks the fact that adherents of naturalism may plausibly hold that there exist certain conceptual links between belief content and behaviour. Given such links, natural selection will favour true belief. A further rather surprising consequence of the existence of (...) such links is this: even if semantic properties are epiphenomenal, unguided evolution will still favour true belief. (shrink)

This paper discusses a wide range of anti-naturalistic argument from reason due to Balfour, Haldane, Joad, Lewis, Taylor, Moreland, Plantinga, Reppert, and Hasker. I argue that none of these arguments poses a serious challenge to naturalists who are identity theorists. Further, I argue that some of these arguments do not even pose prima facie plausible challenges to naturalism. In the concluding part of my discussion, I draw attention to some distinctive differences between Hasker’s anti-naturalistic arguments and the other anti-naturalistic arguments (...) mentioned above.

Argues that characterizing naturalism as a view rather than a research programme and inevitably portrays naturalism either as a self‐defeating thesis or as a view commitment to which would be inconsistent with the core dispositions of the tradition. Thus, the fairest and most plausible characterization of naturalism treats it as a research programme – in particular, a research programme wherein one treats the methods of science and those methods alone as basic sources of evidence.

This paper is a response to Anthony Brueckner's critique of my essay "The Self-Defeating Character of Skepticism," which appeared in Philosophy and Phenomenological Research in 1992. In this reply I contend that the three main avenues by which one might plausibly account for one's self-awareness are unavailable to an individual who is restricted to the skeptic's epistemic ground rules. First, all-encompassing doubt about the world cancels our "external" epistemic access via perception to ourselves as material individuals in the world. Second, (...) one does not have direct cpistemic access to one's substantial self through introspection, since the self as such is not a proper object of inner awareness. Third, we cannot claim, as Descartes did, that we have indirect epistemic access to the substantial self by inference from the occurrence of experiences.The summary conclusion for which I argue is that, if we are to account for our self-knowledge, we cannot adopt the purely subjective epistemological stance that is at the heart of global skepticism. (shrink)

Many have thought that it is impossible to rationally persuade an external world skeptic that we have knowledge of the external world. This paper aims to show how this could be done. I argue, while appealing only to premises that a skeptic could accept, that it is not rational to believe external world skepticism, because doing so commits one to more extreme forms of skepticism in a way that is self-undermining. In particular, the external world skeptic is ultimately committed to (...) believing a proposition P while believing that she shouldn’t believe P, an irrational combination of beliefs. Suspending judgment on skepticism is also problematic, for similar reasons; and, I argue, rational dilemmas are not possible; so, we should believe that skepticism is false. (shrink)

From a number of quarters have come attempts to answer some form of skepticism—about knowledge of the external world, freedom of the will, or moral reasons—by showing it to be performatively self-defeating. Examples of this strategy are subject to a number of criticisms, in particular the criticism that they fail to shift the burden of proof from the anti-skeptical position, and so fail to establish the epistemic entitlement they seek. To these approaches I contrast one way of understanding Kant’s core (...) anti-skeptical arguments in the Critique of Pure Reason. Kant’s goal is the more modest one of showing the applicability of the concepts of substance and cause to experience, against those who might call such application incoherent, or a category mistake. I explain why this goal makes Kant’s approach more promising than those of neo-Kantian practitioners of otherwise structurally-similar strategies. (shrink)

In Chapter 12 of Warrant and Proper Function, Alvin Plantinga constructs two arguments against evolutionary naturalism, which he construes as a conjunction E&N .The hypothesis E says that “human cognitive faculties arose by way of the mechanisms to which contemporary evolutionary thought directs our attention (p.220).”1 With respect to proposition N , Plantinga (p. 270) says “it isn’t easy to say precisely what naturalism is,” but then adds that “crucial to metaphysical naturalism, of course, is the view that there is (...) no such person as the God of traditional theism.” Plantinga tries to cast doubt on the conjunction E&N in two ways.His “preliminary argument” aims to show that the conjunction is probably false, given the fact (R) that our psychological mechanisms for forming beliefs about the world are generally reliable.His “main argument” aims to show that the conjunction E&N is self-defeating — if you believe E&N , then you should stop believing that conjunction.Plantinga further develops the main argument in his unpublished paper “Naturalism Defeated” (Plantinga 1994).We will try to show that both arguments contain serious errors.

Contemporary discussions in metaphysics, epistemology and philosophy of mind are dominated by the presupposition of naturalism. Arguing against this established convention, Jim Slagle offers a thorough defence of Alvin Plantinga's Evolutionary Argument against Naturalism (EAAN) and in doing so, reveals how it shows that evolution and naturalism are incompatible. Charting the development of Plantinga's argument, Slagle asserts that the probability of our cognitive faculties reliably producing true beliefs is low if ontological naturalism is true, and therefore all other beliefs produced (...) by these faculties, including naturalism itself, are self-defeating. He critiques other well-known epistemological approaches, including those of Descartes and Quine, and deftly counters the many objections against the EAAN to conclude that epistemological naturalism should be rejected on the grounds of self-defeat. By situating Plantinga's argument within a wider context and showing that science and evolution cannot entail naturalism, Slagle renders this most common metaphysical view irrational. As such, the book advocates an important reconsideration of contemporary thought at the intersection of philosophy, science and religion. (shrink)

Paul Russell begins his book by rightly noting, “almost all commentators over the past two and a half centuries have agreed that Hume’s intentions in the Treatise should be interpreted in terms of two general themes: skepticism and naturalism” (vii). The skeptical reading interprets Hume’s principal aim as showing that “our ‘common sense beliefs’ (e.g. belief in causality, independent existence of bodies, in the self, etc.) lack any foundation in reason” (4). The naturalist reading interprets Hume’s aims according to the (...) “science of man,” derived from experience and observation. As described in the Introduction to the Treatise, this science is meant to explain the “principles of human nature” and thereby put the other sciences “on a foundation entirely new, and the only one upon which they can stand with any security.” The “riddle” of the Treatise is how to understand the relationship between the skeptical and naturalistic dimensions of the work—dimensions that “seem to be equally essential to what [Hume] is trying to achieve,” but which nevertheless appear “inherently opposed and irreconcilable” (7). Russell puts forward a novel and challenging solution. He argues that the relationship of the skepticism and naturalism in the Treatise can be made intelligible when we see that “it is problems of religion broadly conceived, that hold the contents of the Treatise together as a unified work” (viii). “More specifically,” he goes on, “the direction and structure of Hume’s thought in the Treatise is shaped on one side by his attack on the Christian metaphysics and morals and on the other by his efforts to construct in its place a secular, scientific account of morality.” ...It is difficult to do justice in such a short review to the sophistication of Russell’s analyses. To take one of many examples, Russell explains how Hume’s theory of ideas, rather than something simply adopted from Locke and Berkeley, instead follows Hobbes and expresses irreligious intentions by defending skepticism about our knowledge of God. Russell shows how religious thinkers tried to respond to the claim made by Hobbes that we have no idea of God. Either they insisted that we have knowledge of God through reason rather than through the senses, or they defended the view that our idea of God comes from analogy with ideas of ourselves and of nature. Hume is largely silent about our idea of God, but it is clear, as Russell argues, that he is aware of these debates and that his theory knowingly undermines claims by religious thinkers to possess knowledge of God. We have no simple impressions from which we can derive the idea of God, nor do we have ideas of the divine attributes (power, unity, intelligence, etc.) sufficient to provide us with a clear idea of the divinity. ..... Any criticisms of The Riddle of Hume’s Treatise, however, must be placed within the broader take-away: this book is a triumph and a model for work in the history of philosophy. It offers a powerful reading of the Treatise and of Hume’s intentions in writing it, while also correct- ing common misunderstandings about Hume’s place in early modern thought. It deserves to be read by anyone interested in Hume or in early modern philosophy. (shrink)

Alvin Plantinga has famously argued that naturalism is self-defeating. Plantinga's argument is, at its heart, an argument from analogy. Plantinga presents various epistemic situations and claims of each that (i) a person in such a situation has an undefeated defeater for each of his beliefs, and (ii) a reflective naturalist is in a relevantly similar situation. I present various epistemic situations and claim of each that a person in such a situation does not have an undefeated defeater for each of (...) his beliefs. I further claim that at least some of these situations are more relevantly like the situation faced by the reflective naturalist than any of the situations Plantinga describes. Therefore, Plantinga's argument fails to establish that the reflective naturalist has an undefeated defeater for each of his beliefs and hence fails to establish that naturalism is self-defeating.

Metaphysical naturalism can be taken, roughly, to be the view that there is no God, and nothing beyond nature. Alvin Plantinga has argued that naturalism, in this sense, is self‐defeating. More specifically, he argues that an evolutionary account of human origins gives the naturalist compelling reasons for doubting the reliability of human cognitive faculties, and thus compelling reasons for doubting the truth of any of his beliefs, including naturalism itself. This argument, which has come to be known as the ‘evolutionary (...) argument against naturalism’, has generated a great deal of controversy, and a substantial literature concerning it has grown up as a result. In this paper, I will introduce readers to this literature. I begin by explaining the argument itself, and making clear its intuitive force. I then survey the main objections to it, such as the Perspiration Objection, the ‘Can’t the Naturalist Just Add a Little Something?’ Objection, and the Tu Quoque Objection: in the course of this survey, I pay particular attention to the most interesting of these, a version of the Tu Quoque Objection according to which the problem of evil results in a form of epistemic self‐defeat for the theist that is exactly analogous to the self‐defeat with which the naturalist is allegedly faced in the evolutionary argument. I go on to suggest that, despite the wide range of objections in the literature, the challenge of the evolutionary argument against naturalism is still very much with us, and I conclude by describing some promising directions for future research.

Alvin Plantinga has famously argued that metaphysical naturalism is self-defeating, and cannot be rationally accepted. I distinguish between two different ways of understanding this argument, which I call the "probabilistic inference conception", and the "process characteristic conception". I argue that the former is what critics of the argument usually presuppose, whereas most critical responses fail when one assumes the latter conception. To illustrate this, I examine three standard objections to Plantinga's evolutionary argument against naturalism: the Perspiration Objection, the Tu Quoque (...) Objection, and the "Why Can't the Naturalist Just Add a Little Something?" Objection. I show that Plantinga's own responses to these objections fail, and propose counterexamples to his first two principles of defeat. I then go on to construct more adequate responses to these objections, using the distinctions I develop in the first part of the paper. (shrink)

In this paper I aim to elucidate Wittgenstein’s claim that the so-called dream argument is senseless. Unlike other interpreters, who understand the sentence “I am dreaming” as contradictory or self-defeating, I intend to elucidate in what sense one should understand it as senseless or, more precisely, as nonsensical. In this sense, I propose to understand the above-mentioned claim in light of Wittgenstein’s criticism of skepticism from the _Tractatus logico-philosophicus_ to his last writings. I intend to show that the words “I (...) am dreaming” are nonsensical in the same sense as the alleged proposition “There are physical objects” or the expression of doubt about the existence of external objects.

Though most of analytic philosophy is based upon intuitions, some philosophers are beginning to question whether intuitions are an appropriate basis for philosophical theory. This paper responds to the arguments of some contemporary philosophers who hold that intuitions should not be treated as evidence for anything other than our contingent psychological constitution. It begins with a demonstration that skeptical arguments by Gilbert Harman and Alvin Goldman are variations on an argument with the potential to undermine the use of intuitions in (...) much philosophical inquiry. After a demonstration that Nicholas Sturgeon’s response to Harman’s argument is inadequate, it argues that all of the instances of the skeptical argument are unsuccessful because they are epistemically self-defeating.

The book will discuss and criticize the objections from Blackburn, Searle and Glock to Quine's arguments for the indeterminacy of translation, i.e., that these arguments result in a denial of first-person authority, as well as Hylton’s solution to these objections. The book argues that these objections, as well as Hylton's solution, all rely on a misconstrual of Quine, among other things, that there can be a distinction between meaning and translation for Quine. I will then offer a Strawsonian-Wittgensteinian account of (...) first-person authority and show that this account can work within Quine’s naturalism. (shrink)

I argue that Plantinga’s Proper Function and Evolutionary arguments fail against liberal naturalism defined in a broad sense as the view that „there aren’t any supernatural beings”. The former argument can be interpreted in at least three ways: deductively, inductively and theistically. None of these, however, is successful. The latter argument suffers from several deficiencies of which two major ones are: The unlikelihood of the reliability of our cognitive faculties, given naturalism and evolutionism, is not shown. Agnosticism with respect to (...) the likelihood of our cognitive reliability is insufficient to establish the self-defeating character of naturalistic evolutionism, unless it is also shown that the belief in this reliability lacks an independent warrant. The last condition has been neglected by Plantinga. (shrink)

Philosophical naturalism, according to which philosophy is continuous with the natural sciences, has dominated the Western academy for well over a century; but Michael Rea claims that it is without rational foundation, and that the costs of embracing it are surprisingly high. The first part of World Without Design aims to provide a fair and historically informed characterization of naturalism. Rea then argues compellingly to the surprising conclusion that naturalists are committed to rejecting realism about material objects, materialism, and perhaps (...) realism about other minds. This conclusion is striking, largely because naturalism is often simply identified with materialism, and the remaining two theses are ones that naturalists very typically want to endorse. Rea goes on to examine two alternative research programs: intuitionism and supernaturalism, and argues for the conclusion that intuitionism, under certain circumstances, is self-defeating.World Without Design offers a provocative challenge to philosophical orthodoxy. It will make uncomfortable reading for many philosophers. (shrink)

An extended critical investigation of Plantinga's evolutionary argument against naturalism (EAAN). -/- I wrote this a couple of years ago as a way of thinking through the argument, but now lack the ambition to revise it into a paper. (It's too long to be a paper, too short and too narrowly focused on one person's argument to be a book.) Rather than let it age in private, I'm sharing it publicly for anyone interested in Plantinga's argument.
