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 (...) class='Hi'>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)

Inspired by Plantinga’s Evolutionary Argument Against Naturalism (EAAN), we develop an argument—the “Scriptural Argument Against Dogmatic Protestantism” (SAADP)—that Protestants who accept the doctrine of sola scriptura cannot reasonably hold that Catholic and Eastern churches are in doctrinal error. If sola scriptura is true and Catholic and Eastern Churches have fallen into error, it is improbable that any Protestant can reliably form true beliefs about controversial points of Christian doctrine, including sola scriptura or suggestions (...) that Catholic and Eastern Christians are in error. We evaluate potential responses to SADDP, considering how SAADP should affect ecumenical doctrinal debates. (shrink)

In this essay, we put forth a novel solution to Plantinga’s Evolutionary Argument Against Naturalism, utilizing recent work done by Duncan Pritchard on radical skepticism. Key to the success of Plantinga’s argument is the doubting of the reliability of one’s cognitive faculties. We argue (viz. Pritchard and Wittgenstein) that the reliability of one’s cognitive faculties constitutes a hinge commitment, thus is exempt from rational evaluation. In turn, the naturalist who endorses hinge epistemology can deny the (...) key premise in Plantinga’s argument and avoid the dilemma posed on belief in the conjunction of naturalism and evolution.

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.

Only in rational creatures is there found a likeness of God which counts as an image . . . . As far as a likeness of the divine nature is concerned, rational creatures seem somehow to attain a representation of [that] type in virtue of imitating God not only in this, that he is and lives, but especially in this, that he understands (ST Ia Q.93 a.6).

In his recently published two-volume work in epistemology,1 Alvin Plantinga rounds out the discussion (in characteristic fashion) with a subtle and ingenious argument for a striking claim: in this case, his conclusion is that belief in evolutionary naturalism is irrational. Now this claim is not of itself so very surprising; the tantalizing feature here lies rather in the nature of the argument itself. Plantinga contends that taking seriously the hypothesis of evolutionary naturalism [hereafter, N&E] (...) ought to undermine one's confidence in the reliability of our basic cognitive faculties. And if one withholds belief in cognitive reliability, it seems that one ought to likewise refrain from believing propositions that are the output of such faculties. And, for evolutionary naturalists, one such output is belief in evolutionary naturalism itself. Hence, quite apart from comparative evidential considerations that might lead one to prefer theism (or one of its competitors) to N&E, but rather owing to a sort of internal inconsistency (in a suitably broad sense), belief in N&E is shown to be epistemically defective. A bold and intriguing suggestion indeed. Let us take a closer look. (shrink)

Alvin Plantinga's evolutionary argument against naturalism makes the case that the conjunction of evolutionary theory and naturalism cannot be rationally believed, as, if both evolutionary theory and naturalism were true, it would be highly unlikely that our cognitive faculties are reliable. I present Plantinga's evolutionary argument against naturalism and survey a theory of meaning espoused by Robert Brandom, known as semantic inferentialism. I argue that if one accepts semantic (...) inferentialism, as it is developed by Brandom, then Plantinga's motivation for the evolutionary argument against naturalism is undermined. (shrink)

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)

Alvin Plantinga’s evolutionary argument against naturalism argues that the probability of our possessing reliable cognitive faculties, given the truth of evolution and naturalism, is low, and that this provides a defeater for naturalism, if the naturalist in question holds to the general truths of evolutionary biology. Stephen Law has recently objected to Plantinga’s evolutionary argument against naturalism by suggesting that there exist conceptual constraints governing the content a belief can (...) have given its relationships to other things, including behaviour . I show that Law’s objection fails, since it offers an auxiliary hypothesis to naturalism which is itself improbable. I consider multiple variants of the CC thesis, demonstrating that each is improbable, and that any weaker version with greater prior probability is compromised by a failure to render the relevant datum – the reliability of our cognitive faculties – probable. Thus, Law’s objection to Plantinga’s argument fails. (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 (...) class='Hi'>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)

Alvin Plantinga's evolutionary argument against naturalism states that evolution cannot produce warranted beliefs. In contrast, according to Plantinga, Christian theism provides properly functioning cognitive faculties in an appropriate cognitive environment, in accordance with a design plan aimed at producing true beliefs. But does theism fulfill criteria I–III? Judging from the Bible, God employs deceit in his relations with humanity, rendering our cognitive functions unreliable. Moreover, there is no reason to suppose that God's purpose would be to (...) produce true beliefs in humans. Finally, from the theistic/religious perspective, it is impossible to tell whether observations have natural or supernatural causes, which undermines an appropriate cognitive environment. Reliable identification of deceit or miracles could alleviate these problems, but the theistic community has failed to resolve this issue. Dismissal of parts of the Bible, or attempts to find alternative interpretations, would collapse into skepticism or deism. Thus, Plantinga's problem of epistemic warrant backfires on theism. (shrink)

There are three major theses in Plantinga’s latest version of his evolutionary argument against naturalism. (1) Given materialism, the conditional probability of the reliability of human cognitive mechanisms produced by evolution is low; (2) the same conditional probability given reductive or non-reductive materialism is still low; (3) the most popular naturalistic theories of content and truth are not admissible for naturalism. I argue that Plantinga’s argument for (1) presupposes an anti-materialistic conception of content, and (...) it therefore begs the question against materialism. To argue for (2), Plantinga claims that the adaptiveness of a belief is indifferent to its truth. I argue that this claim is unsupported unless it again assumes an anti-materialistic conception of content and truth. I further argue that Plantinga’s argument for (3) is not successful either, because an improved version of teleosemantics can meet his criticisms. Moreover, this version of teleosemantics implies that the truth of a belief is (probabilistically) positively related to its adaptiveness, at least for simple beliefs about physical objects in human environments. This directly challenges Plantinga’s claim that adaptiveness is indifferent to truth. (shrink)

Alvin Plantinga has argued that evolutionary naturalism (the idea that God does not tinker with evolution) undermines its own rationality. Natural selection is concerned with survival and reproduction, and false beliefs conjoined with complementary motivational drives could serve the same aims as true beliefs. Thus, argues Plantinga, if we believe we evolved naturally, we should not think our beliefs are, on average, likely to be true, including our beliefs in evolution and naturalism. I argue herein that our (...) cognitive faculties are less reliable than we often take them to be, that it is theism which has difficulty explaining the nature of our cognition, that much of our knowledge is not passed through biological evolution but learned and transferred through culture, and that the unreliability of our cognition helps explain the usefulness of science.

In “The evolutionary argument against naturalism: a Wittgensteinian response,” DeVito and McNabb (Int J Philos Relig 92(2):91–98, 2022, 10.1007/s11153-022-09832-3) propose a Wittgensteinian argument against Alvin Plantinga’s evolutionary argument against naturalism. In their paper, they seek to establish symmetry between a component of Plantinga’s premise and the premise of the radical skeptic. The first premise of Plantinga’s argument assumes the possibility of doubting the reliability of our cognitive abilities. The Radical (...) skeptic doubts we have rational grounds to refute being brains in vats. DeVito and McNaab use hinge epistemology and Pritchard’s strategy against the radical skeptic to undermine Plantinga’s premise. This paper offers an alternative argument based on hinge epistemology against Plantinga’s argument. Relying on the various types of certainties Wittgenstein discussed, I argue that some scientific facts are among our certainties and hinges. Evolution (i.e., the theory of evolution by natural selection) is a well-established scientific fact and a hinge. As a result, in Plantinga’s first premise, we have two hinges: evolution and the reliability of our cognitive abilities. I will argue that given that hinges cannot trump one another, we can have these two hinges in place, and therefore, by endorsing hinge epistemology, there is another argument that shows why Plantinga’s argument cannot undermine naturalism if one accepts evolution.

In this paper, I examine Plantinga’s (1993, 2000, 2011) Evolutionary Argument Against Naturalism (EAAN). While there has been much discussion about Plantinga’s use of probabilities in the argument, I contend that insufficient attention has been paid to the question of how we are to interpret those probabilities. In this paper, I argue that views Plantinga defends elsewhere limit the range of interpretations available to him here. The upshot is that the EAAN is more limited in (...) its applicability than Plantinga alleges. (shrink)

In this paper, an evolutionary multiverse argument against naturalism (EMAAN) is presented: E1. In an evolutionary multiverse, phenomena have variable evolutionary ages. E2. After some time T, the development of the empirical sciences will be evolutionarily conserved. E3. The phenomena with an evolutionary age above T are methodologically supernatural. Entities are classified according to whether they are (1) physical and spatiotemporal, (2) causally efficacious, and (3) either observed by or explanatorily necessary for the (...) empirical sciences. While the conjunction of (1) and (2) is taken to be sufficient for existence in reality, the negation of (3) defines methodological supernaturalness. EMAAN uses a generalization of evolutionary theory, namely cosmological natural selection, to argue that phenomena evolve that fulfill conditions (1) and (2), but not (3). This shows that methodologically supernatural phenomena have a clear epistemology according to a theory that is grounded in the commitments of naturalism. Supernatural phenomena are not observed by the empirical sciences because the empirical sciences themselves are supernaturally guided and predestined to develop according to an evolutionarily conserved plan. In spite of this scientific plan, there is room for afterlives and supernaturality in the everyday experience. (shrink)

Alvin Plantinga’s evolutionary argument against naturalism (EAAN) claims that if both naturalism (N) and evolutionary theory (E) are true, then all our beliefs are unreliable (premiss 1). Consequently, given N&E, the belief in N&E is unreliable (premiss 2) and N&E is self-defeating (conclusion). The empirical verification argument against naturalism (EVAAN) is more cautious and improves EAAN by withstanding a rejoinder of the evolutionary naturalist to premiss 1. EVAAN claims that non-abstract (...) beliefs that are not empirically verifiable are unreliable, given N&E (premiss 1a). This anticipates the evolutionary naturalist’s claim that empirical verifications play a crucial role in peer assessments and sexual selection of intelligence, and that, therefore, N&E makes empirically verifiable beliefs often reliable (premiss-1 rejoinder). However, even then it can be argued that the belief in N&E is unreliable, given N&E (premiss 2), because N&E is neither abstract, nor empirically verifiable (premiss 1b). EVAAN distinguishes reliably verifiable intelligence from metaphysical intelligence and claims that, if N&E is true, humans are lacking metaphysical intelligence. This paper also contains an argument against EAAN, by supporting the premiss-1 rejoinder. (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.

Intending to have a constructive dialogue with the combination of evolutionary theory (E) and metaphysical naturalism (N), Alvin Plantinga’s evolutionary argument against naturalism (EAAN) takes the reliability of human cognition (in normal environments) as a purported explanandum and E&N as a purported explanans. Then, he considers whether E&N can offer a good explanans for this explanandum, and his answer is negative (an answer employed by him to produce a defeater for N). But I will (...) argue that the whole EAAN goes wrong by assuming that R is a qualified explanandum crying out for scientific explanations, since it cannot meet either of the two criteria for any scientifically qualified explanandum: Realizability Criterion and Informativeness Criterion. Hence, EAAN is simply setting a task that E&N, as a scientific theory, will not care at all. Therefore, EAAN cannot substantially shake E&N. (shrink)

ABSTRACTSome proponents of the evolutionary debunking argument against moral realism believe that replies that assume substantive moral claims beg the question. In this paper, I give a new account of what's wrong with such replies. On this account, many realists beg the question when they rely on substantive moral claims in their replies to the argument, but naturalists do not. While this account generalizes to some other domains, it allows perceptual and inductive realism to remain undebunked.

Recently in these pages it has been argued that a relatively straightforward version of an old argument based on evolutionary biology and psychology can be employed to support the view that innate ideas are a naturalistic source of metaphysical knowledge. While sympathetic to the view that the “evolutionary argument” is pregnant with philosophical implications, I show in this paper how it needs to be developed and deployed in order to avoid serious philosophical difficulties and unnecessary complications. (...) I sketch a revised version of the evolutionary argument, place it in a new context, and show that this version in this context is not vulnerable to the standard criticisms levelled against arguments of this general type. The philosophical import of this version of the argument lies not in any metaphysical conclusions it sanctions directly, but in the support it lends to the metaphilosophy of commonsense. (shrink)

Resumen Recientemente la ciencia cognitiva de la religión ha permitido desarrollar argumentos evolutivos desacreditadores, los cuales buscan poner en entredicho no solo la racionalidad sino la verdad del teísmo. Dado que hay dos formas de concebir la racionalidad y la justificación epistémicas, a saber, la internalista y la externalista, cabe preguntarse ¿de qué modo tales argumentos afectan al teísmo? El objetivo de este artículo es responder a esta cuestión mediante una reconstrucción y evaluación de tres argumentos evolutivos desacreditadores subproductistas contra (...) la racionalidad del teísmo que Dennett sostendría. Sostendré que solo uno de los tres argumentos de Dennett es posiblemente válido. igualmente, mostraré que el argumento adicional del sesgo cognitivo es probablemente exitoso en socavar la justificación internalista y externalista del teísmo. Finalmente, mostraré que estos argumentos evolutivos desacreditadores pueden ser invalidados indirectamente a partir del argumento evolutivo desacreditador en contra del naturalismo desarrollado por Plantinga, al cual se le puede contraponer el argumento lógico cancelador de la epistemología reformada.Recently, the cognitive science of religion has allowed the development of evolutionary debunking arguments, which seek to challenge not only rationality but the truth of theism. Since there are two ways of conceiving epistemic rationality and justification, viz., the internalist and the externalist, one may wonder ¿how such arguments affect theism? The purpose of this article is to answer this question through a reconstruction and evaluation of three evolutionary debunking arguments against the rationality of theism that Dennett would hold. I will argue that only one of the three Dennett's evolutionary debunking arguments is possibly valid. I will also show that the argument of cognitive bias is probably successful in undermining both the internalist and externalist justification of theism, under certain conditions. Finally, I will show that this arguments can be indirectly disproved from evolutionary argument against naturalism developped by Plantinga, argument to which one can counterpose logical defeater argument against the reformed epistemology.

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

The aim of this article is to identify the strongest evolutionary debunking argument against moral realism and to assess on which empirical assumptions it relies. In the recent metaethical literature, several authors have de-emphasized the evolutionary component of EDAs against moral realism: presumably, the success or failure of these arguments is largely orthogonal to empirical issues. I argue that this claim is mistaken. First, I point out that Sharon Street’s and Michael Ruse’s EDAs both involve (...) substantive claims about the evolution of our moral judgments. Next, I argue that combining their respective evolutionary claims can help debunkers to make the best empirical case against moral realism. Some realists have argued that the very attempt to explain the contents of our endorsed moral judgments in evolutionary terms is misguided, and have sought to escape EDAs by denying their evolutionary premise. But realists who pursue this reply can still be challenged on empirical grounds: debunkers may argue that the best, scientifically informed historical explanations of our moral endorsements do not involve an appeal to mind-independent truths. I conclude, therefore, that the empirical considerations relevant for the strongest empirically driven argument against moral realism go beyond the strictly evolutionary realm; debunkers are best advised to draw upon other sources of genealogical knowledge as well.

Albert Casullo (2000, 2003) and Shane Oakley (2011) argue that dilemma arguments against epistemic naturalism, such as those offered by Laurence BonJour (1998) and Harvey Siegel (1984), are such that, whatever strength they have against naturalism applies equally to moderate rationalist accounts of a priori justification. They conclude that dilemma arguments are, therefore, insufficient for establishing an advantage for moderate rationalism over naturalized epistemology. I argue that both Casullo's and Oakley's criticisms depend on an illicit assumption, (...) namely, that dilemma arguments presuppose a meta-justificatory demand that naturalists provide non-circular support for their basic sources of evidence. I argue that this assumption is not necessary for the force of dilemma arguments, and I construct a version that avoids this misreading. I conclude that, although there remain strategies for responding to dilemma arguments, they constitute a challenge naturalists must take seriously. (shrink)

Alvin Plantinga’s Evolutionary Argument Against Naturalism aims to show that the conjunction of contemporary evolutionary theory (E) with the claim that there is no God (N) cannot be rationally accepted. Where R is the claim that our cognitive faculties are reliable, the argument is: The probability of R given N and E is low or inscrutable.Anyone who sees (1) and accepts (N&E) has a defeater for R, and this defeater cannot be defeated or deflected.Anyone (...) who has an undefeated, undeflected defeater for R has an undefeated, undeflected defeater for everything she believes.Therefore she has an undefeated, undeflected defeater for (N&E).Plantinga (2011) defends the second premise. It examines and rejects several candidate defeater defeaters and defeater deflectors. One candidate is Millikan’s teleosemantics. I show that Plantinga’s motives for rejecting teleosemantics as a defeater deflector are inadequate. I then show that teleosemantics is not on its own an adequate defeater deflector. Then I offer an additional premise that constitutes a defeater deflector in conjunction with teleosemantics. (shrink)

In his recently published Where the Conflict Really Lies: Science, Religion, & Naturalism 2011 Alvin Plantinga criticises Paul Draper’s evolutionary argument against theism as part of a larger project to show that evolution poses no threat to Christian belief. Plantinga focuses upon Draper’s probabilistic claim that the facts of evolution are much more probable on naturalism than on theism, and with regard to that claim makes two specific points. First, Draper’s probabilistic claim contradicts theism’s necessary (...) falsehood; unless Draper wishes to acknowledge that theism is necessarily true, his claim commits him to theism’s contingency and so sets him at odds with a mainstream that sees God’s existence as decidedly noncontingent. Second, Plantinga argues that Draper’s probabilistic claim is, even if true, overwhelmed by counterclaims about facts that are more likely on theism than naturalism. I argue this critique of Draper depends upon a serious error, and that Plantinga overlooks the full implications of his own presuppositions. Correcting these shortcomings shows that Plantinga’s own probabilistic-apologetics (e.g., the ‘Evolutionary Argument Against Naturalism’) requires theism’s contingency no less than does Draper’s atheology.

Evolutionary debunking arguments, whether defended by Street (2006), Joyce (2006), or others against moral realism, or by Plantinga (1993, 2011) and others against atheism, seek to determine the implications of the still-dominant worldview of naturalism. Examining them is thus a critical component of any defense of a theistic philosophy of nature. Recently, several authors have explored the connection between evolutionary debunking arguments against moral realism (hence: EDAs) and Plantinga’s evolutionary argument against (...) naturalistic atheism (hence: EAAN). Typically, responses in this vein have been critical of EDAs, arguing that they are in some way self-undermining. Different critics have argued that, in the course of defending the EAAN, the theist loses her best response to the probabilistic argument from evil for atheism. Here, I provide the first systematic comparison of all three arguments—EDAs, the EAAN, and the problem of evil—and suggest that the first charge succeeds while the second fails. (shrink)

The author identifies the structure of Sharon Street's skeptical challenge to non-naturalist, normative epistemic realism as an argument that NNER is liable to reliability defeat and then argues that Street's argument fails, because it itself is subject to reliability defeat. As the author reconstructs Street's argument, it is an argument that the normative epistemic judgments of the realist could only be probabilistically sensitive to normative epistemic truths by sheer chance. The author then recaps Street's own naturalist (...) translation of normative epistemic judgments into purely descriptive, contingent probability statements, and argues that, on her own terms, the reasoning that leads her to rationally believe in evolutionary theory could only be probabilistically sensitive to the relevant purely descriptive, contingent probabilities by sheer chance. The author's argument is addressed to Street, but it applies to all evolutionary naturalist accounts of epistemic rationality. The author explains how his argument differs from Plantinga's Evolutionary Argument Against Naturalism and shows how it avoids the objections to Plantinga's EAAN. The author closes with the outline of an explanation of how evolution could have made human reasoning probabilistically sensitive to metaphysically necessary normative epistemic standards, even though those standards did not exert and, indeed, could not have exerted any kind of causal influence on the evolutionary process.

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)

I critically discuss a recent innovation in the debate surrounding the plausibility of rational choice theory : the appeal to evolutionary theory. Specifically, I assess Gigerenzer and colleagues’ claim that considerations based on natural selection show that, instead of making decisions in a RCT-like way, we rely on ‘simple heuristics’. As I try to make clearer here, though, Gigerenzer and colleagues’ arguments are unconvincing: we lack the needed information about our past to determine whether the premises on which they (...) are built are true—and, hence, we cannot tell whether they, in fact, speak against RCT.

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.

In this article, I critically assess Peter van Inwagen’s rejection of C. S. Lewis’s argument against Naturalism. Van Inwagen argues that Lewis (1960) errs on two fronts. First, he falsely assumes that Naturalism implies Spinozism: that the only way the world could be is the way it is. Second, the central premise of Lewis’s argument is asserted without proof. I argue that van Inwagen is mistaken on both counts.

The dissertation involves an examination of recent work in Social Epistemology. In particular, I am concerned with the question of how one's social position could affect judgments regarding evidence and confirmation. To answer this question I undertake an investigation of feminist epistemology and philosophy of science. Feminist epistemologists have raised criticisms of the traditional analysis of knowledge by arguing against the primacy of the individual and for a more thorough-going analysis of the community in accounts of knowledge. This shift, (...) in my view, is an important contribution toward a more complete theory of knowledge. Yet feminist epistemology is a controversial contributor to the area of social epistemology generally construed. Thus, in the first chapter I offer a defense of the contributions of feminist epistemology to analytic philosophy, against its various critics. ;In Chapters Two and Three I examine feminists' reliance on Naturalistic models of theory-choice such as Quinean Holism or the later Wittgenstein's Social Constructivism. I argue that the reliance on these models is a tactical mistake for feminists since these models are based on problematic accounts of meaning and truth. Alternatively, I advocate the adoption of a realist meaning theory along the lines proposed by Katz, as well as a rationalized epistemology in the service of explaining deductive and inductive inference. My argument involves showing how realism and rationalism entail the kind of strong program of justification and rational censure which is required if feminists want to successfully condemn existing biased practices. ;Consequently, I propose a reformulation of the distinction between a context of discovery and context of justification. My reformulation differs from the past positivist distinction in that "discovery" rather than being wholly random and subjective, is instead reflective of patterns of social experience. "Justification" is conceived of as more sensitive to the epistemic privilege of varying social standpoints. However, a separation is still maintained between how one comes to arrive at a belief and the methods for justifying that belief. My conclusion is that a partnership between rationalized epistemology and feminist theory can provide rich possibilities for both disciplines. (shrink)
