Perhaps no one has done more in the last 30 years to advance thinking in the metaphysics of modality than has Alvin Plantinga. Collected here are some of his most important essays on this influential subject. Dating back from the late 1960's to the present, they chronicle the development of Plantinga's thoughts about some of the most fundamental issues in metaphysics: what is the nature of abstract objects like possible worlds, properties, propositions, and such phenomena? Are there possible (...) but non-actual objects? Can objects that do not exist exemplify properties? Plantinga gives thorough and penetrating to all of these questions and many others. This volume contains some of the best work in metaphysics from the past 30 years, and will remain a source of critical contention and keen interest among philosophers of metaphysics and philosophical logic for years to come.

An exchange between Patrick Grim and Alvin Plantinga regarding Cantorian arguments against the possibility of an omniscient being.

Paul Churchland argues that Plantinga’s evolutionary argument against naturalism is unsuccessful and so we need not accept its conclusion. In this paper, we respond to Churchland’s argument. After we briefly recapitulate Plantinga’s argument and state Churchland’s argument, we offer three objections to Churchland’s argument: (1) its first premise has little to recommend it, (2) its second premise is false, and (3) its conclusion is consistent with, and indeed entails, the conclusion of Plantinga’s argument.

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)

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.

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.

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. (shrink)

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.

The ontological argument for the existence of God has enjoyed a recent renaissance among philosophers of religion. Alvin Plantinga's modal version is perhaps the most notable example. This essay critically examines Plantinga's rendition, uncovering both its strengths and weaknesses. The author concludes that while the argument is probably formally valid, it is ultimately unsound. Nonetheless, Plantinga's version has generated much interest and discussion. The author spends some time uncovering the reasons for the argument's powerful intuitive appeal. He (...) concludes his essay by appraising Pruss's recent defence of Plantinga's argument. (shrink)

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

Some atheistic philosophers have argued that God could have created a world with free moral agents and yet absent of moral evil. Using possible world semantics, Alvin Plantinga sought to defuse this logical form of the problem of evil. In this critical note, Leslie Allan examines the adequacy of Plantinga's argument that the existence of God is logically compatible with the existence of moral evil. The veracity of Plantinga's argument turns on whether his essential use of counterfactual (...) conditionals preserves the logic of this type of conditional. (shrink)

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

I would like to get this published somewhere; but who would publish it?

This article criticises Alvin Plantinga’s claim that ‘basic’ design beliefs, which arise without a conscious inference, have more positive epistemic status than non-basic ones and that we cannot evaluate the probabilities involved in inferential, inductive design arguments.

My aim in this paper is to critically assess two opposing theses about the epistemology of religious belief. The first one, developed by John Mackie, claims that belief in God can be justified or warranted only if there is a good argument for the existence of God. The second thesis, elaborated by Alvin Plantinga, holds that even if there is no such argument, belief in God can be justified or warranted. I contend that the first thesis is plausibly false, (...) because belief in God is not just like a scientific hypothesis, and the second thesis is likely true if epistemic externalism is the correct view. However, even if the second thesis is true, I argue that to work on good arguments for God’s existence is unavoidable in order to cope with a new version of the Great Pumpkin objection, as well as to achieve other relevant purposes such as to convince rational observers outside the theistic community that belief in God is likely justified or warranted.

This article aims to examine Alvin Plantinga's speech at Biola University which name is: ‘‘Science and Religion, Where the Conflict Really Lies.’’ In order to achieve this purpose, after giving a description of the emergence of conflict between two disciplines, the ideas of Plantinga is examined through his speech and articles. The remainder of the article conducts a critical examination of his thesis in the light of Islamic viewpoint.

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)

This is an article on the metaphysics of Alvin Plantinga. It is from the Blackwell Companion to Metaphysics (2009).

In this article we intend to present Alvin Plantinga’s epistemology by showing the way in which its central concepts: the Reidian foundationalism, the partial critique of evidentialism, warrant, proper function, reliability and externalism - are logically interrelated. A section of this article is reserved to the critiques of his account of warrant brought by Peter Klein and Richard Feldman and to the way in which Plantinga answered them, by developing the concepts of cognitive maxi- and mini-environment. In the (...) end we will see the way in which Plantinga’s epistemology relates to both modernism and postmodernism. (shrink)

In this paper we will give a critical account of Plantinga’s well-known argument to the effect that the existence of an omnipotent and morally perfect God is consistent with the actual presence of evil. After presenting Plantinga’s view, we critically discuss both the idea of divine knowledge of conditionals of freedom and the concept of transworld depravity. Then, we will sketch our own version of the Free-Will Defence, which maintains that moral evil depends on the misuse of human (...) freedom. However, our argument does not hinge on problematic metaphysical assumptions, but depends only on a certain definition of a free act and a particular interpretation of divine omniscience. (shrink)

For the past 30 years, Alvin Plantinga's work in the metaphysics of modality has been both insightful and innovative; it is high time that his papers in this area be collected together in a single volume. This book contains 11 pieces of Plantinga's work in modal metaphysics, arranged in chronological order so one can trace the development of his thought on matters modal. In what follows I will lay out the principal concepts and arguments in these papers.

J.L. Mackie’s version of the logical problem of evil is a failure, as even he came to recognize. Contrary to current mythology, however, its failure was not established by Alvin Plantinga’s Free Will Defense. That’s because a defense is successful only if it is not reasonable to refrain from believing any of the claims that constitute it, but it is reasonable to refrain from believing the central claim of Plantinga’s Free Will Defense, namely the claim that, possibly, every (...) essence suffers from transworld depravity.

Encyclopedia article about "reformed epistemology".

In contemporary debates in religious epistemology, theistic philosophers provide differing responses to the evidentialist argument against religious beliefs. Plantinga’s strategy is to argue that evidence is not needed to justify religious beliefs while Swinburne’s strategy is to argue that religious beliefs can be justified by evidence. However, in Aquinas’ account of religious epistemology, he seems to employ both strategies. In his account of religious knowledge by faith, he argues that evidence is unnecessary for religious beliefs. But in his account (...) of religious knowledge by science, he argues that there is evidence for religious beliefs. In this paper, I argue that there is no real dichotomy between Plantinga’s and Swinburne’s responses to the evidentialist argument. From a Thomistic perspective, Reformed Epistemology and Natural Theology are different but compatible responses to Evidentialism. (shrink)

In this paper I argue that, although Alvin Plantinga’s Felix Culpa theodicy appears on only two pages of his recent book Where the Conflict Really Lies: Science, Religion and Naturalism (2011) (i.e. 58-59), it is of pivotal importance for the book as a whole. Plantinga argues that there is superficial conflict but deep concord between science and monotheism, and that there is superficial concord but deep conflict between science and naturalism. I contend that the weakness of the Felix (...) Culpa theodicy lends support to the view that there is more than superficial conflict between science and monotheism, and offer an alternative response to the challenge of evil which suggests that there might be, after all, concord between science and (religious) naturalism.

Alvin Plantinga’s theory of knowledge, as developed in his Warrant trilogy, has shaped the debates surrounding many areas in epistemology in profound ways. Plantinga has received his share of criticism, however, particularly in his treatment of belief in God as being “properly basic”. There has also been much confusion surrounding his notions of warrant and proper function, to which Plantinga has responded numerous times. Many critics remain unsatisfied, while others have developed alternative understandings of warrant in order (...) to rescue Plantinga’s theory from certain objections. The most promising of such attempts fall under the broad category of “virtue epistemology” or a “virtue-theoretic” approach. The work being done in virtue epistemology is still in its early stages and a consensus on what actually constitutes virtue epistemology has yet to be reached. While some have attempted to structure an entire theory of knowledge based on the virtues possessed by the knower, others have focused more on the role of epistemic virtues as an attempt to supplement existing theories, including Plantinga’s. In this paper, I will offer an analysis of what such an attempt might look like and evaluate the potential success of broadening Plantinga’s original model. -/- My proposal is that certain features of a virtue-theoretic approach (also referred to as “agent-reliabilism”) could improve Plantinga’s model in significant ways. Not only would such a broadened approach be better equipped to handle common objections, but it would also be better suited to contribute an enhanced understanding of the task of epistemology, one that seeks to discover multiple epistemic goods other than what has been traditionally confined to the realm of knowledge. I conclude by applying this approach to Plantinga’s treatment of theistic belief in Warranted Christian Belief and by articulating a few of the ways in which epistemic virtues can increase the degree of warrant enjoyed by such belief.

Alvin Plantinga is an American-born philosopher of religion and one of the leading advocates of contemporary Christian philosophy. Plantinga deals with numerous problems of the monotheistic Christian religion, including the problem of religious pluralism. One of the most common questions an atheist asks a believer is, "Why your God and not someone else's?" Therefore, this paper aims to present Plantinga's answer to the question of religious pluralism. We will achieve this goal by developing Plantinga's theory of (...) "proper functioning", a thesis that atheism represents a state of incorrect functioning of cognitive mechanisms. We can respond to the problem of religious pluralism through positive or negative apologetics. Plantinga has chosen negative apologetics, arguing that the believer is under no obligation to justify the truth of his beliefs when confronted with the problem of religious pluralism. Although Plantinga provides numerous convincing arguments supporting his position, we will show that we can provide a positive apologetic by returning to the foundations of Plantinga's understanding of intentionality and mental representations. In so doing, we will demonstrate a broader range of ways a believer can defend his epistemic position and connect Plantinga's epistemology of religion in relevant ways to contemporary theories of cognitive psychology and philosophy of cognition.

Cornelius Van Til and Alvin Plantinga represent two strands of American Protestant philosophical thought influenced by Dutch neo-Calvinism. This paper compares and synthetizes their models of knowledge in non-Christians given the noetic effects of sin and non-Christian worldview commitments. The paper argues that Van Til’s distinction between the partial realization of the antithesis in practice and its absolute nature in principle correlates with Plantinga’s insistence on prima facie–warranted common-sense beliefs and their ultimate defeasibility given certain metaphysical commitments. Van (...) Til endorsed more radical claims than Plantinga on epistemic defeat in non-Christian worldviews, the status of the sensus divinitatis, and conceptual accuracy in knowledge of the world. Finally, an approach to the use of evidence in apologetics is developed based on the proposed synthesis. This approach seeks to make more room for evidence than is generally recognized in Van Tilianism, while remaining consistent with the founder’s principles. (shrink)

In May 2010, philosophers, family and friends gathered at the University of Notre Dame to celebrate the career and retirement of Alvin Plantinga, widely recognized as one of the world's leading figures in metaphysics, epistemology, and the philosophy of religion. Plantinga has earned particular respect within the community of Christian philosophers for the pivotal role that he played in the recent renewal and development of philosophy of religion and philosophical theology. Each of the essays in this volume engages (...) with some particular aspect of Plantinga's views on metaphysics, epistemology, or philosophy of religion. Contributors include Michael Bergman, Ernest Sosa, Trenton Merricks, Richard Otte, Peter VanInwagen, Thomas P. Flint, Eleonore Stump, Dean Zimmerman and Nicholas Wolterstorff. The volume also includes responses to each essay by Bas van Fraassen, Stephen Wykstra, David VanderLaan, Robin Collins, Raymond VanArragon, E. J. Coffman, Thomas Crisp, and Donald Smith. (shrink)

Alvin Plantinga has played a pivotal role in bringing theological questions and ideas into the broad philosophical, predominantly non-theistic community. His “Advice to Christian Philosophers” (1983) was the turning point in the history of philosophical theology. In his “Advice” Plantinga talks about how best to be a Christian in philosophy. He suggests that Christian intellectuals should become more autonomous from the rest of philosophical world, display more unity, and express greater Christian self-confidence. These advices, however, are addressed not (...) to just any intellectual of a Christian affiliation. He addresses them to those 1) who have graduated from a conservative Christian college, 2) who have obtained a PhD in philosophy, and 3) who continue their career as professional philosophers. That means that the person should be well acquainted with the traditional Christian doctrine and practice, should be well versed in the contemporary analytic philosophy, and should be an acknowledged member of the established philosophical community. It would be a mistake to apply Plantinga’s “Advice” to a person who does not meet all of the three requirements. The present day situation in Russia is such that there is a dramatic shortfall of those intellectuals who satisfy all of the three Plantinga’s requirements. It is still premature for Russian Christian philosophers to become autonomous from the rest of the philosophical community, to establish Christian philosophical clusters, and to display Christian self-confidence in the face of the non-theistic majority. Philosophical theology in Russia is currently in its “pre-Plantingan” phase. In order to improve this situation I suggest reversing Plantinga’s advices into their opposites. Russian Christian philosophers ought to learn how to operate within the broad philosophical community. They should familiarize themselves with the contemporary analytic philosophy and its methods, and they should become acknowledged members of the established professional circles. Then, and only then, philosophical theology in Russia can enter its post-Plantingan era. (shrink)

This article presents Alvin Plantinga’s views on epistemic justification. The first part situates Plantinga’s epistemological views in the context of his epistemology of religion and debates of general epistemology. The second part discusses Plantinga’s argument that the internalism of 20th century epistemology stems from deontologism and that the views on the epistemic justification of analytic philosophers reflect the relationship between classical deontologism and classical internalism. The last part points to the objections with which the Plantinga’s conception (...) met and tries to balance the depth and weakness of its position. (shrink)

O objetivo deste artigo é avaliar criticamente duas teses opostas sobre a epistemologia da crença religiosa: a primeira, defendida por Norman Geisler, afirma que a crença em Deus só pode ser racionalmente justificada ou garantida se houver argumentos ou evidências em favor da existência de Deus. A segunda tese, elaborada por Alvin Plantinga, sugere que a crença em Deus pode ser garantida, mesmo que o teísta não conheça qualquer evidência para a existência de Deus, mesmo que ele não acredite (...) que haja tais evidências e mesmo se não existir, de fato, tais evidências. Na comparação das duas teses, conclui-se que a primeira tese é falsa, pois a crença em Deus não necessariamente precisa ser tida como uma ‘hipótese científica’, enquanto a segunda é provavelmente verdadeira, caso Deus exista.

O objetivo central desta pesquisa é comparar as credenciais epistêmicas da crença em Deus na epistemologia religiosa de dois dos principais pensadores da filosofia analítica da religião contemporânea: Alvin Plantinga (1932- ) e Richard Swinburne (1934- ). Mais precisamente, busca-se investigar como a crença na existência de Deus pode obter status epistêmico positivo, ou seja, como pode ser intelectualmente justificada ou racional ou ainda avalizada, a partir de comparações, contrastes ou complementações que podem ser feitos entre as propostas dos (...) dois filósofos. Deste modo, será avaliado como Plantinga e Swinburne lidam com algumas questões fundamentais da filosofia analítica da religião ligadas à natureza e à relação entre fé e razão. Para que tal objetivo seja concretizado, foram escolhidos três méritos ou credenciais epistêmicas: a justificação deontológica, a racionalidade e o aval. Na primeira parte desta tese, serão clarificados os conceitos fundamentais ligados ao debate sobre a relação entre fé e razão na filosofia analítica contemporânea a fim de elucidar o problema central desta pesquisa; além disso, será esclarecido o que significa precisamente uma crença ter o mérito da justificação, da racionalidade ou do aval. Na segunda parte, são apresentadas as duas propostas epistemológicas que serão comparadas, a saber, a Epistemologia Reformada de Alvin Plantinga e o balanço evidencial probabilístico proposto pela teologia natural de Richard Swinburne. Por fim, visa-se comparar criticamente as duas propostas e analisar a possibilidade de articulação entre essas duas diferentes abordagens. (shrink)

The title of this article is ambiguous in the sense that it may direct the attention to either theism as a system of beliefs of persons who are referring to particular facts that serve as external grounds for the foundation of theist beliefs or to theism as a system of beliefs of persons who are convinced of theism’s truth on grounds that are intrinsic to their belief . Traces of both conceptions of theism can be found in Alvin Plantinga’s (...) thesis of the ‘proper basicality’ of religious belief, for instance in the distinction between evidence of the ‘on the basis of …’- type and evidence of the ‘inclination’- type. However, these two types of evidence do only lead to doxastic experience. In order to be warranted with respect to a particular knowledge claim, beliefs must be produced by noetic capacities that function properly, i.e. according to their design plan and in contexts that are appropriate to these capacities. This externalist epistemology exerts its greatest power in the criticism of the ‘evidentialist objection to belief in God’. However, it raises a number of objections with respect to its positive account of theism. When every community of thinkers creates its own relevant set of examples in order to establish criteria of proper basicality, does this not lead to skepticism? And, can doxastic experience not be honoured as a proper response to being called by divine discourse and, correspondingly, be seen as the relational foundation of theist belief? (shrink)

This is a book review of Deane-Peter Baker (ed.), Alvin Plantinga (New York: Cambridge Univ. Press, 2007).

The paper is a critique of Alvin Plantinga’s notion that belief in God is properly basic - evidence is not needed to justify such belief - in light of Thomas Aquinas’ religious epistemology. The latter’s epistemology proves that, while evidence is not a necessary condition for belief in God based on his Summa Theologica since such belief is evidence itself from his De Veritate, there is sufficient evidence that justifies such belief. First, I argue that Plantinga’s total rejection (...) of evidence as a justification for belief in God renders such belief purely subjective. To rationally ground this purely subjective belief, Plantinga introduces the notion of justification-conferring conditions. Second, following Thomas Aquinas’ thought, Plantinga’s justification negates his claim that belief in God is properly basic because the said justification-conferring conditions seem to function as an evidence for belief in God. I will conclude the work by claiming that although evidence is not a necessary condition for belief in God, it is epistemically sufficient to justify the said belief. (shrink)

In the naturalism and evolutionism context, the ultimate objective and function of cognitive faculties is adaptation, survival and reproduction. Our cognitive faculties are not developed to generate true beliefs, therefore, but to have adapt behavior. Alvin Planatinga is not at ease with naturalism idea. To him, the problem with naturalism is the non-existence of proper understanding on the manner by which the belief and behavior are interrelated, thus, he concludes that the reliability of cognitive faculties are founded on low naturalistic (...) evolutionism; because any alleged argument against these faculties, first, requires reliable perceptual faculties and next, if we realize lack of reliability in these faculties we developed self-defeating belief, consequently, in both the cases naturalism face criticism. Plantiga’s criticism on naturalism view as to reliability of cognitive faculties has made some philosophers encounter problems like: 1) high probability of interrelating casual belief and behavior, 2) argument based on personal incredulity, 3) lack of distinction between reflective and non-reflective knowledge, 4) finding independent evidence for reliability as to escape self-defeating, 5) the external status of mental states and 6) the problem of circle. To the authors here, except the problem of circle, Plantiga has been able to find proper answer for the rest of five problems. The objective here is to analyze, complete, expand and criticize Plantiga’s notion in rejecting the atheistic naturalism through the ability to secure cognitive faculties to unveil consistency of the new scientific findings with religious beliefs.

By focussing on the logical relations between scientific theories and religious beliefs in his book Where the Conflict Really Lies, Alvin Plantinga overlooks the real conflict between science and religion. This conflict exists whenever religious believers endorse positive factual claims to truth concerning the supernatural. They thereby violate an important rule of scientific method and of common sense, according to which factual claims should be endorsed as true only if they result from validated epistemic methods or sources.
