Plantinga’s God and Other Minds, Reformed Epistemology articles, and Warrant Trilogy are all part of the same epistemological project. Although the project develops in phases focusing progressively on anti-theism, evidentialism, and internalism, the epistemology is consistently a Reidian particularism. It follows Roderick Chisholm’s famous particularist strategy for finding an epistemic criterion, uses principles of common sense from Thomas Reid as clear cases of beliefs satisfying that criterion, and applies that criterion to belief in God in order to show that (...) this belief is epistemically respectable. Understanding this will help to clarify Plantinga’s philosophical contributions to our understanding of religious belief. In my article I introduce Plantinga’s epistemological sources, explain the structure of his project, overview its development in these three phases, and correct some misunderstandings of Plantinga that arise from inattention to his Reidian particularism. I also show how Reidian particularism itself suggests an improvement to Plantinga’s epistemology which his critics often recommend: that we recognize that evidence for the existence of God, even if it is not necessary for theistic belief to be warranted, may yet be valuable.

Plantinga famously argues against evidentialism that belief in God can be properly basic. But the epistemology of cognitive faculties such as perception and memory which produce psychologically non-inferential beliefs shows that various inferentially justified theoretical beliefs are epistemically prior to our memory and perceptual beliefs, preventing the latter from being epistemically basic. Plantinga's analogy between the sensus divinitatis and these cognitive faculties suggests that the deliverances of the sensus divinitatis cannot be properly basic either. Objections by and on (...) behalf of Plantinga to this argument are considered. (shrink)

My topic is Alvin Plantinga’s ’solution’ to one of the many forms that the problem of evil takes: the modal abstract form. This form of the problem is abstract in that it does not deal with the amounts or kinds of evil which exist, but only with the fact that there is some evil or other. And it is modal in that it concerns the compossibility of the following propositions, not any evidential relation between them: God is omnipotent, omniscient, (...) and wholly goodand There is evil in the world.

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.

In this paper, we attempt to show that if Plantinga’s free will defence succeeds, his O Felix Culpa theodicy fails. For if every creaturely essence suffers from transworld depravity, then given that Jesus has a creaturely essence (as we attempt to show), it follows that Incarnation and Atonement worlds cannot be actualized by God, in which case we have anything but a felix culpa.

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.

Alvin Plantinga’s religious epistemology has been used to respond to many debunking arguments against theistic belief. However, critics have claimed that Plantinga’s religious epistemology conflicts with skeptical theism, a view often used in response to the problem of evil. If they are correct, then a common way of responding to debunking arguments conflicts with a common way of responding to the problem of evil. In this paper, I examine the critics’ claims and argue that they are right. I (...) then present two revised versions of Plantinga’s argument for his religious epistemology. I call the first a 'religion-based argument' and the second an 'intention-based argument'. Both are compatible with skeptical theism, and both can be used to respond to debunking arguments. They apply only to theistic beliefs of actual persons who have what I call 'doxastically valuable relationships' with God – valuable relationships the goods of which entail the belief that God exists.

While Plantinga has famously argued that acceptance of neo-Darwinian theory commits one to the rejection of naturalism, Plantinga’s argument is vulnerable to an objection developed by Evan Fales. Not only does Fales’ objection undermine Plantinga’s original argument, it establishes a general challenge which any attempt to revitalize Plantinga’s argument must overcome. After briefly laying out the contours of this challenge, we attempt to meet it by arguing that because a purely naturalistic account of our etiology cannot (...) explain the correlation between our preference for simplicity and simplicity’s ability to serve as a veridical method of theory selection, the scientific realist is committed to the rejection of naturalism.

Thomas Reed argues that the Christian, if apprised of Plantinga's central claims in Warranted Christian Belief, should be agnostic regarding Christianity's central tenets. Reed models his argument on Plantinga's own argument against naturalism, according to which naturalists have a built-in defeater for their epistemology. Reed bases his argument on the contention that if Christian theism cannot be shown or demonstrated, rational Christians should refrain from believing. Not only does Reed's contention not follow, but he confuses logically possible defeaters (...) with actual defeaters and ignores Plantinga's claims regarding the Aquinas/Calvin model and the proper basicality of belief in God. (shrink)

In “Supralapsarianism, or ‘O Felix Culpa,’” Alvin Plantinga turns from defensive apologetics to the project of Christian explanation and offers a supralapsarian theodicy: the reason God made us in a world like this is that God wanted to create a world including the towering goods of Incarnation and atonement—goods which are appropriate only in worlds containing a sufficient amount of sin, suffering, and evil as well. Plantinga’s approach makes human agents and their sin, suffering and evil, instrumental means (...) to the end of God’s cosmic aims. I press the objection that means/end conceptuality is inadequate to explain how God is loving and merciful (as opposed to abusive) towards human sinners and sufferers. Plantinga’s theodicy remains under-developed without an explanation of how Incarnation and atonement benefit them. (shrink)

Alvin Plantinga has proposed a fascinating epistemology, one which he considers to be completely naturalized. Critical to his epistemology is the notion of a 'design plan' which circumscribes the function of organs or systems. Ernest Sosa has objected to Plantinga by using Donald Davidson's Swampman thought experiment, according to which a bolt of lightning randomly assembles a physical duplicate of a person, including one's neurological structure. The Swampman would have no design plan and as such would constitute a (...) counterexample to Plantinga's epistemology. Plantinga responded to Sosa that the Swampman may not be metaphysically possible so he is not disturbed by it conflicting with his epistemology and, at any rate, we would still ascribe functions (and thus design plants) the Swampman's organs and systems. In this essay I will argue that 1) a stronger case can be made demonstrating that the Swampman is not metaphysically possible and 2) at any rate the Swampman is not possible in an epistemological sense; that is, it could not know anything.

Few thinkers have had as much impact on contemporary philosophy as has Alvin Plantinga. The work of this quintessential analytic philosopher has in many respects set the tone for the debate in the fields of modal metaphysics and epistemology and he is arguably the most important philosopher of religion of our time. In this volume, a distinguished team of today's leading philosophers address the central aspects of Plantinga's philosophy - his views on natural theology; his responses to the (...) problem of evil; his contributions to the field of modal metaphysics; the controversial evolutionary argument against naturalism; his model of epistemic warrant and his view of epistemic defeat; and his recent work on mind-body dualism. Also included is an appendix containing Plantinga's often referred to, but previously unpublished, lecture notes entitled 'Two Dozen Theistic Arguments', with a substantial preface to the appendix written by Plantinga specifically for this volume.

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 "Warranted Christian Belief" is without question one of the central texts of the Reformed epistemology movement. Critiques of Plantinga's defence have been both multiple and varied. As varied as these responses are, however, it is my contention that many of them amount to the same thing. It is the purpose of this paper to offer an overview of the main lines of attack that have been directed as Plantinga's project, and thereafter to show how many, (...) if not most, of these objections can be understood as versions or aspects of the same criticism, what I call the 'Inadequacy Thesis'.

Alvin plantinga has presented various counterexamples to the argument from analogy for other minds. I argue that the implausibility of the counterexample inferences plantinga offers depends not on a weakness essential to the analogical argument but rather on features peculiar to the inferences he provides. My procedure is to establish a number of necessary conditions for any acceptable analogical argument and then to show plantinga's counterexamples fail to meet these conditions. I then construct an analogical argument for (...) other minds which meets all these conditions and hence appears acceptable and invulnerable to plantinga's objections. Other responses to plantinga are also criticized. (shrink)

Die folgenden miteinander zusammenhängenden Themen werden erörtert : der Essentialismus, die Trans-Welt-Identität, der ontologische Gottesbeweis und der Glaube, Gott könne jede beliebige Welt erschaffen. Plantingas Einschätzung der De-re-Modalität stellt sich als fehlerhaft heraus, wenn seine Überzeugung, Menschen dürften nicht mit ihren Körpern gleichgesetzt werden, auch überzeugender ist. Leibniz würde jedoch mit guten Gründen der Behauptung Plantingas nicht vorbehaltlos zustimmen, daß Menschen ihrem Wesen nach immateriell sind. Plantinga hat Recht, wenn er — z. B. im Gegensatz zu Leibniz — die (...) Auffassung vertritt, daß dasselbe Individuum in mehr als einer möglichen Welt existieren kann und daß — trotz Tooley — die Rede von möglichen Welten kohärent ist. Van Invagen hat gezeigt, daß Plantingas Version des ontologischen Gottesbeweises nicht sicherer ist als die von Leibniz und daß sie verwundbar bleibt durch eine Kritik Jerome Shaffers. Aber Plantinga hat Recht, wenn er Leibniz' Ansicht, Gott könne jede beliebige Welt schaffen, zurückweist und als „Leibniz' Fehler" abstempelt. (shrink)

Discussion of Alvin Plantinga's book, "Where the Conflict Really Lies".

Alvin Plantinga s Warranted Christian Belief has very quickly become one of the most influential books in philosophy of religion. In this collection of essays, German philosophers, theologians and a mathematician deal critically with several aspects of Plantinga s seminal work. In a long essay, Plantinga answers these critics.".

Alvin Plantinga Warranted Christian Belief (New York NY: Oxford University Press, 2000). In the two previous volumes of his trilogy on ‘warrant’, Alvin Plantinga developed his general theory of warrant, defined as that characteristic enough of which terms a true belief into knowledge. A belief B has warrant if and only if: (1) it is produced by cognitive faculties functioning properly, (2) in a cognitive environment sufficiently similar to that for which the faculties were designed, (3) according to (...) a design plan aimed at the production of true beliefs, when (4) there is a high statistical probability of such beliefs being true. Thus my belief that there is a table in front of me has warrant if in the first place, in producing it, my cognitive faculties were functioning properly, the way they were meant to function. Plantinga holds that just as our heart or liver may function properly or not, so may our cognitive faculties. And he also holds that if God made us, our faculties function properly if they function in the way God designed them to function; whereas if evolution (uncaused by God) made us, then our faculties function properly if they function in the way that (in some sense) evolution designed them to function.

Plantinga underestimates the prospects for probabilistic atheism. He employs a flawed mathematical rendition of the atheist's crucial claim, (1) and he misunderstands the utility (1) would have for the atheist.

Alvin Plantinga wrote a probabilistic critique of historical arguments for the kernel of Christianity. It is based on the fact that, generally, the more complex a conjunction, the lower its probability. The paper provides elementary insights into the epistemology of Plantinga, probability calculus, and the role of this calculus in contemporary epistemology. It introduces a concept of a good argument, explains in which sense and why, according to Plantinga, no good arguments for Christianity exist, and discusses the (...) following replies. The probability that every argument for Christianity fails can be low. Even if Christianity is less probable than its proper propositional parts, it can be still be probable, whether on the same or on some enhanced body of evidence. Finally, there have been detailed probabilistic arguments for Christianity yielding results significantly different from Plantinga’s cursory estimates. (shrink)

In seeking to undermine Mackie’s logical argument from evil, Plantinga assumes that Mackie’s argument regards it as a necessary truth that a wholly good God would eliminate all evil that he could eliminate. I argue that this is an interpretative mistake, and that Mackie is merely assuming that the theist believes that God’s goodness entails that God would eliminate all evil that he could eliminate. Once the difference between these two assumptions, and the implausibility of Plantinga’s assumption, are (...) brought out, Plantinga’s celebrated critique of Mackie’s argument can be seen to be far less compelling than is often assumed to be the case.

Variations on the ontological argument for most minimal and most mediocre beings.

The view of names that plantinga advances in "the nature of necessity" seems to have unacceptable consequences for names in propositional attitude contexts. In this paper, I argue that he is unsuccessful in his attempt to avoid these consequences.

I argue that reliabilist warrant should not require that a true belief have been produced in accordance with a design plan. At least sometimes, it seems sufficient that there be an intent for the faculty to have the reliable outcomes it in fact has. This pertains to the notion of warrant of Alvin Plantinga.

In response to a collection of essays in Jonathan Kvanvig's (1996) Warrant in Contemporary Epistemology: Essays in Honor of Plantinga's Theory of Knowledge, Alvin Plantinga notices that certain Gettier-style examples undermine his (1993b) canonical account of epistemic warrant as delineated in Warrant and Proper Function. In hopes to clarify how his account survives Gettier's purchase, he (1996; 2000) argues that a belief has warrant sufficient for knowledge only when produced in a favorable cognitive mini-environment. In Warranted Christian Belief (...) Plantinga (2000) specifies a condition required for a cognitive mini-environment's favorability. I argue that this condition falls prey to counterexample. Then I investigate a possible solution, which I reason fails as well. (shrink)

By taking ‘existence in reality’ to be a great-making property and ‘God’ to be the greatest possible being, Plantinga skillfully presents Anselm’s ontological argument. However, since he proves God’s existence by virtue of a premise, “God (a maximally great being) is a possible being”, that is true only if God actually exists; his argument begs the question of the existence of God.

After summarizing Plantinga’s critique of “classical foundationalism” and his substitute, Reformed epistemology, the paper argues that Reformed epistemology has so many problems that it is not an adequate substitute for classical foundationalism. Given Plantinga’s reformed epistemology, believers of any religion could have “knowledge of their God.” This is because Plantinga has not set forth the justifying conditions necessary to distinguish between “properly basic beliefs” as opposed to improperly basic beliefs. Given such problems, it is more reasonable to (...) stick with classical foundationalism rather than Plantinga’s substitute. (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. (...) class='Hi'>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)

In Warrant and Proper Function, Alvin Plantinga claims that metaphysical naturalism, when joined to a naturalized epistemology, is self-undermining. Plantinga argues that naturalists are committed to a neoDarwinian account of our origins, and that the reliability of our cognitive faculties is improbable or unknown relative to that theory. If the theory is true, then we are in no position to know that, whereas theism, if true, underwrites cognitive reliability. I seek to turn the tables on Plantinga, showing (...) that neoDarwinism provides strong reasons for expecting general cognitive reliability, whereas the likelihood of that relative to theism is unknowable.

Alvin Plantinga, in the ninth chapter ofThe Nature of Necessity, sets out a defence of the Free Will Defence (FWD)2.

Finally, I shall set out a criticism of Plantinga’s argument.

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)

In this paper, I argue that Plantinga maintains it is possible to come to know that Christianity is true, but only from the inside. Further, since Plantinga argues that one’s judgments about the epistemic status of Christian belief depend upon one’s prephilosophical metaphysical views, his position amounts to the claim that the Christian community has privileged access to truth and that non-Christians are ill-equipped to evaluate their beliefs. The upshot of Plantinga’s position is, I suggest, that people (...) from different communities will disagree about the epistemic status of religious belief, and reason is simply incapable of adjudicating those disputes.

The foreknowledge problem involves two assumptions. First, that “God once believed that an event would occur now” is about the past. Second that it is equivalent to “God once existed and the event is occurring now.” These, Plantinga argues, are incompatible. But he makes assumptions. First, that equivalent propositions are both about a given time, or neither are. Second, that if a proposition is about a given time, so is its negation. Third, that if two propositions are about a (...) given time, so is their conjunction. These, though plausible, are incompatible. (shrink)
