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).

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'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.

This chapter contains sections titled: * Notes.

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)

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)

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)

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)

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 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)

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.

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 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)

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)

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.

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)

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.

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)

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

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)

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.

We aim to further develop and evaluate the prospects of a uniquely Islamic extension of the Standard Aquinas/Calvin model. One obstacle is that certain Qur’an passages such as Surah 8:43–44 apparently suggest that Muslims have reason to think that Allah might be deceiving them. Consistent with perfect/maximally good being theology, Allah would allow such deceptions only if doing so leads to a greater good, so such passages do not necessarily give Muslims reason to doubt Allah’s goodness. Yet the possibility of (...) deception of the faithful threatens to provide a subjective defeater for the (epistemic) reliability of their cognitive faculties. (‘Even if Allah can be morally good while deceiving, how do you know you aren’t being deceived for a greater good on a more macro level, such as about the nature of the Qur’an?’) Similar in structure to Alvin Plantinga’s Evolutionary Argument Against Naturalism (EAAN), this defeater threatens to undermine all of a Muslims warrant claims. We consider and evaluate the reply that there are other Qur’anic passages and/or additional conceptual resources in the Islamic tradition that provide grounds for thinking that God’s faithfulness or truthfulness is more centrally and securely embedded in a Muslim’s noetic structure than such doubts. Specifically, we will argue that under certain conditions, there exists a subjective defeater for some Muslims that, unlike McNabb’s approach, isn’t based off of the proper function condition but Plantinga’s truth aimed condition.

This paper critiques Alvin Plantinga's evolutionary argument against naturalism. Plantinga argues that, since unplanned evolution is not likely to produce trustworthy cognitive faculties, evolutionary naturalists cannot rationally believe anything--including naturalism itself. This paper contends that this argument rests on a crucial but faulty inference from the premise that the probability that our cognitive faculties are reliable given unplanned evolution is low or inscrutable. The conclusion that evolutionary naturalists cannot rationally believe in unplanned (...) evolution does not follow from this "probability thesis." If the thesis were amended to claim that the probability of reliable cognitive faculties given unplanned evolution is low (as opposed to "low or inscrutable"), then it would follow that naturalists cannot trust their cognitive faculties; but this amended thesis is demonstrably false, and thus Plantinga's evolutionary argument against naturalism fails.

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.

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)

This paper offers a commonsense response to Alvin Plantinga’s evolutionary argument against naturalism. The first stage of that argument concludes that the probability that our cognitive faculties are reliable (R) is low or inscrutable given the claims that naturalism is true (N) and that our cognitive faculties came into existence by way of the mechanisms of evolution (E)—i.e., that P(R/N&E) is low or inscrutable. The second stage claims that the fact that P(R/N&E) is low (...) or inscrutable constitutes a defeater for belief in R, for anyone who endorses N&E. For the purposes of this paper, I will grant to Plantinga the conclusion of the first stage of his argument—that P(R/N&E) is low or inscrutable when specified to us. My contention is simply that, given what we can know via commonsense, this does not necessarily constitute a defeater for R for the supporter of N&E. (shrink)

This chapter contains sections titled: Can a Material Thing Think? Tooley's Reply to the Evolutionary Argument against 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’s Evolution Argument against Naturalism (Sum.)...................39 In the article the proposition is put forward that naturalism connected with evolutionism is an attitude involved in many problems, and the rationality of the naturalist attitude is not credible. The proposition is proven on the basis of the evolution argument against the form of naturalism that assumes that evolution theories are true, which was formulated by Alvin Plantinga. In the article it is shown that the (...) naturalist explanation of human cognitive mechanisms is self-refuting. The naturalist claims that man\'s cognitive system originated by way of evolutionary processes, and the aim of these processes is man\'s survival, and not the truth of his beliefs; hence - on the basis of such reasoning - one may doubt if all beliefs are true, including the naturalist one. Hence in the article it is shown that the naturalist\'s all beliefs, and among them the belief that \'God does not exist\', cannot be credible. An indirect aim of the evolution argument against naturalism is also intellectual defense of credibility of the theist image of the world. The starting point of the article is presentation of the argument that half a century earlier was formulated by Clive Staples Lewis. Next the details of Plantinga\'s argumentation and controversies connected with it are shown. In the final part of the article the relation between naturalism and theism is discussed. In conclusion it is stated that the naturalist attitude does not attain what is required, so that a naturalist could state that it is the way he thinks; and this is why he is not able to threaten Christian theism.

In Michael Ruse's recent publications, such as Taking Darwin Seriously (1998) and Evolutionary Naturalism (1995), he has advocated a certain sort of evolutionary epistemology and has argued that it implies a rejection of metaphysical realism (MR) in favor of a position that he calls “internal realism” (IR). Additionally, he has maintained that, insofar as his evolutionary epistemology implies a rejection of MR in favor of IR, it escapes the kind of argument against naturalism (...) that Alvin Plantinga makes in his Warrant and Proper Function (1993). In this article I explain the relevant views and arguments of Ruse and Plantinga, and I critically engage with Ruse's views, arguing that (1) his case for rejecting MR has no essential connection to evolutionary considerations; (2) his case for rejecting MR depends upon internalist assumptions about the nature of knowledge that are in need of some kind of defense; and (3) given his implicit internalism and his commitment to IR, his argument for rejecting MR can be used against his IR.

Naturalistic naturalized epistemology combines ontological naturalism with naturalized epistemology. Ontological naturalism is the view that nothing exists other than spatio-temporal beings embedded within a space-time framework. Naturalized epistemology is a view about the nature of knowledge characterized by its commitment to externalism and the idea that knowledge consists in beliefs reliably generated by cognitive mechanisms operating in a suitable environment. Alvin Plantinga has provided a much discussed evolutionary biological argument against naturalistic naturalized epistemology. In this (...) article I defend naturalistic naturalized epistemology by refuting Plantinga's replies to two important criticisms of his argument. /// La epistemología naturalizada naturalista combina el naturalismo ontológico con la epistemología naturalizada. El naturalismo ontológico sostiene que no existe nada más que seres espacio-temporales inmersos en un marco espacio-temporal. La epistemología naturalizada sostiene que la naturaleza del conocimiento se caracteriza por su compromiso con el externismo, y la idea de que el conocimiento consiste en creencias generadas de manera confiable mediante mecanismos cognitivos que operan en un entorno adecuado. Alvin Plantinga ha propuesto un muy discutido argumento biológico evolucionista contra la epistemología naturalizada naturalista. En este artículo defiendo esta epistemología refutando las réplicas de Plantinga a dos críticas importantes a su argumento. (shrink)

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)

In my essay, I will argue that evolution does not undermine naturalism. This is because Alvin Plantinga’s evolutionary argument against naturalism rests on a false and unmotivated premise and is thus invalid. My argument consists of two parts: In the expository part, I outline Plantinga’s evolutionary argument against naturalism in considerable detail (section 2). In the argumentative part, I firstly pose William Ramsey’s challenge to Plantinga’s probabilistic claim that the reliability (...) of human cognitive faculties is low and critically examine Plantinga’s response in order to reinforce it (section 3). Secondly, I attack Plantinga’s understanding of human evolution, which motivates his cognitive skepticism, as being unduly narrow (section 4). (shrink)

This chapter explores global debunking arguments, debunking arguments that aim to give one a global defeater. I defend Alvin Plantinga’s view that global defeaters are possible and, once gained, are impossible to escape by reasoning. They thereby must be extinguished by other means: epistemically propitious actions, luck, or grace. I then distinguish between three types of global defeater—pure-undercutters, undercutters-because-rebutters, and undercutters-while-rebutters—and systematically consider how one can deflect such defeaters. Lastly, since I draw insights from the literature on perhaps the most (...) widely discussed global debunking argument in the literature, Plantinga’s evolutionary argument against naturalism, I end up responding to many potential problems for it. This includes the so-called conditionalization problem, as well as those raised by Bergmann (2002), Law (2012), Deem (2018), Hendricks and Anderson (2020), and Wielenberg (in Craig and Wielenberg (2021)).

In the final chapter of Warrant and Proper Function, Alvin Planting a presents an “evolutionary argument against naturalism” (where naturalism is the claim that there are no supernatural beings). According to this argument, the conjunction of naturalism and evolution cannot be rationally believed by anyone who understands its epistemic implications. In this paper, I argue that if Plantinga’s evolutionary argument is sound, it follows that (what I call) perceptive naturalists have no (...) propositional knowledge. Since it is plausible that perceptive naturalists do have some propositional knowledge, I infer that the evolutionary argument (EA) is unsound. However, I conclude the paper with the suggestion that even if EA is unsound, it may still provide important insights about the epistemic shortcomings of naturalism. (shrink)

This collection of eleven critical essays, together with Plantinga's replies, examines his evolutionary argument against naturalism (EAAN). All but one of the eleven are printed here for the first time, all are of high quality, and all receive Plantinga's trademark treatment -- rigorous, perceptive, thorough. In view of the numerous arguments, sub-arguments and observations advanced by the eleven against EAAN, his responses amount to a tour de force . It would take too long to sort (...) through the point-counterpoint with a view to laying out the many interconnections, valuable though that would be. Instead, after a sketch of EAAN, I summarize some of the key objections raised by the eleven, together with Plantinga's replies, then conclude with an objection of my own to what Plantinga calls the heart of his argument.

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. (shrink)
