My major dispute with Michael Tooley’s response (“Plantinga’s New Argument against Materialism”) to my original article is with his philosophy of mind. Tooley’s objection depends on a functionalist account of mental states such as beliefs, desires and intentions. I offer reasons to reject functionalism and, hence, the same goes for any objection to my argument that is based on or presupposes functionalism.

This is the third volume in Alvin Plantinga's trilogy on the notion of warrant, which he defines as that which distinguishes knowledge from true belief. In this volume, Plantinga examines warrant's role in theistic belief, tackling the questions of whether it is rational, reasonable, justifiable, and warranted to accept Christian belief and whether there is something epistemically unacceptable in doing so. He contends that Christian beliefs are warranted to the extent that they are formed by (...) properly functioning cognitive faculties, thus, insofar as they are warranted, Christian beliefs are knowledge if they are true.

I discuss three objections to essentialism. The first objection is from Gilbert Harman, who claims that because numbers can be identified or reduced to sets it follows that numbers cannot have essential properties. In the second objection, William Kneale argues for the conclusion that objects have essential properties only relative to a certain way of specifying or selecting the object. Kneale's argument suffers from a de re/de dicto confusion and the disambiguated reading of his argument is unsound. The (...) third objection, Quine's mathematical cyclist, contains a similar confusion. (shrink)

In Warranted Christian Belief, Alvin Plantinga makes use of his earlier two books, Warrant: the Current Debate and Warrant and Proper Function, to show how it is possible for someone to have a warranted belief that God exists and that all of the great things of the Christian Gospel are true even if the believer is unable to give any argument to support these beliefs. Three objections are lodged against Plantinga’s position. First, the alleged sensus divinitatis and the (...) internal instigation of the Holy Spirit are crucially disanalogous to the cognitive faculties, such as memory and perception, in the standard package, thereby destroying his argument based on an analogy between the former and the latter. Second, in order to defeat defeaters for these beliefs one must give arguments, thus merely relocating the point at which the believer must produce argumentative support for her belief. Third, there are moral defeaters for exclusivist basic theistic and Christian beliefs based on the undesirable consequences of such beliefs. (shrink)

The question is: how should a theist think of justification or positive epistemic status? The answer I suggest is: a belief B has positive epistemic status for S only if S’s faculties are functioning properly (i.e., functioning in the way God intended them to) in producing B, and only if S’s cognitive environment is sufficiently similar to the one for which her faculties are designed; and under those conditions the more firmly S is inclined to accept B, the more (...) positive epistemic status it has for her. I conclude by making some qualifications and applications and exmaining some objections. (shrink)

This chapter contains sections titled: Can a Material Thing Think? Tooley's Reply to the Evolutionary Argument against Naturalism.

I try to clear up a couple of misunderstandings in William Craig’s review. The first has to do with the difference between what I call “Historical Biblical Criticism” and historical scholarship. I claim there is conflict between the first and Christian belief; I don’t for a moment think there is conflict between historical scholarship and Christian belief. The second has to do with Platonism, theism and causality. I point out that theism has the resources to see abstract objects (...) as like divine thoughts, in which case they are not causally isolated; this offers a reply to Paul Benacerraf’s suggestion that if, as on Platonism, abstract objects are causally isolated from everything, then there is no way in which we could come to know them or anything about them.

The Ontological Argument for the existence of God has and puzzled philosophers ever since it was first formulated by St. Anselm. I suppose most philosophers have been inclined to reject the argument, although it has an illustrious line of defenders extending to the present and presently terminating in Professors Malcolm and Hartshorne. Many philosophers have tried to give general refutations of the argument-refutations de- signed to show that no version of it can possibly succeed-of which the most important is, perhaps, (...) Kant's objection, with its several contemporary variations. I believe that none of these general refutations are successful; in what follows I shall support this belief by critically examining Kant's objection. (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)

ABSTRACT The individual-community relationship has always been one of the most fundamental topics of social sciences. In sociology, this is known as the micro-macro relationship while in economics it refers to the processes, through which, individual actions lead to macroeconomic phenomena. Based on philosophical discourse and systems theory, many sociologists even use the term "emergence" in their understanding of micro-macro relationship, which refers to collective phenomena that are created by the cooperation of individuals, but cannot be reduced to individual actions. (...) "Emergence" theories attempt to explain the nature of society as a complex system by examining how individuals and their relationships lead to the creation of integrated and macro-social phenomena such as markets, educational systems, cultural beliefs, and shared social practices. As a prelude to activity, every researcher has to answer the question from the methodological point of view, how is it possible to study the behavior of social groups and how can we gain knowledge about the laws related to social groups? Anyone who deals with humanities and social sciences or any reality and phenomenon that affects human beings, inevitably deals with the reality that is emerging. In fact, emergence occurs when one level of reality emerges radically from another level. Examples of emergent levels of reality include how the mind emerges from the body; or the way society emerges from human beings. Therefore, when there is an emerging factor, different scientific disciplines should be used, because it is inevitable to talk about social affairs, psychology and neurobiology, as well as physical and even chemical. -/- INTRODUCTION Since its beginning in the 19th century, sociology has faced the fundamental question of what a social phenomena stands for? At a glance, sociologists deal with the study of social groups, collective behavior, institutions, social structures, social networks, and social dynamics, and ultimately all such phenomena are composed of individuals. Therefore, social phenomena seem to have no independent ontological status, and in this case, sociology is ultimately about reducible individuals. Different approaches about the micro-macro relationship, using the concept of "emergence", argue that although collective phenomena are created by individuals, they cannot be reduced to individual action. The term "emergence" is used to distinguish "emergent results" from " Procedural results". Results are called Procedural that can only be calculated by adding or subtracting the causes that act together. On the contrary, they are emergent outcomes that are qualitatively novel compared to the causes from which they originate. An example of such emergent results is mental characteristics that emerge from neural processes, but are not considered among the characteristics of neural processes of components - which are their origin. Philosophical debates about emergentism and reductionism focus on the mind-brain relationship, but as many philosophers have noted, they can be generalized to apply to any hierarchical set of features. The cognitive revolution reactivated a 19th century controversy between theorists of Identity and dualism. The theorists of Identity believe in reductionist materialism and elimination of metaphysics, according to which the mind is nothing more than the biological, while the dualists believe that the mind and the brain are distinct from each other. Emergence has been considered as a third way between the theories of Identity and dualism. -/- METHODOLOGY Interdisciplinarity Is fundamentally indicated by the dominance of open systems as well as social and emerging systems at different levels. Therefore, as long as we are facing a new emergentism, there will necessarily be different fields and an interdisciplinary method. The commonality of social sciences and cognitive sciences on the issue of emergence provides the possibility of interaction and exchange of concepts between these two for deeper research. Therefore, in this research, apart from the concepts of Subvenience and downward causation, we have used multiple realization and wildly disjunctive, which are used to explain the emerging concept in cognitive sciences, including neurobiology, psychology, and philosophy. For analytical and interdisciplinary approaches, after examining the concepts of subvenience, and wildly disjunctive, Individualistic and collectivist emergentism have been reviewed. And then their adequacy is criticized and evaluated in meeting strong emergence conditions. -/- FINDINGS Philosophers of the mind have been able to define the conditions of irreducibility and downward causation, which are essential for strong emergence, by using the principle of subvenience with the help of multiple realization and wildly disjunctive principles. Therefore, by definition, emergentist individualism suffers from the problem of how to explain downward causality and irreducibility, and emergentist collectivism faces the challenge of reification. The analysis of the challenges facing the two methodological approaches of individualism and collectivism leads us to three unresolved issues about the emerging phenomenon, which are realism, downward causality, and mechanism. Despite the differences in the stances of these two approaches regarding the aforementioned triple problems, individualists and collectivists both agree that some social characteristics are reducible; and some others are irreducible due to their complexity, the determination of which, depends on the case study of the mechanism of emergence of each social characteristic. -/- CONCLUSION An emergence that is consistent with reductionism is called a weak emergence. And strong emergence includes the principle of irreducibility and downward causality. According to strong emergence, the characteristics of social phenomena have downward causal power, which cannot be reduced to the causal forces. The principle of subvenience, together with multiple realization and wildly disjunctive, can provide the conditions of irreducibility and downward causality, which are essential conditions of strong emergence. Based on the philosophical analysis of two methodological approaches, individualist and collectivist, it can be concluded that emergentist individualism suffers from the problem of how to explain downward causality and irreducibility, and reification collectivism faces the challenge of reification. The analysis of the problems faced by these two approaches leads us to three unresolved issues, which are realism, downward causality, and mechanism. individualist emergentists acknowledge the existence of emergent social characteristics, but despite this, they believe that these characteristics are not real but merely analytical constructs that require explanation based on individuals and their mutual actions. But collectivists argue that emergentism yields a categorical ontology and supports social realism. They accept the dependence of social characteristics on individuals, but claim that social entities and structures are ontologically independent. Individualists and collectivists both agree that some social characteristics are reducible; and others are irreducible due to their complexity; and the only way to recognize this is to engage in empirical studies of the mechanisms and temporal processes of "emergence" that create social characteristics. -/- NOVELTY The newness of this compact article is as follows: a) Presenting an interdisciplinary approach using the analysis of philosophy of cognitive sciences, including the philosophy of mind, neurobiology and psychology to formulate the issue of social emergence; b) Criticizing individualist and collectivist methodological approaches to the issue of social emergence and explaining the sufficiency and shortcomings of both in providing weak and strong emerging conditions; c) Explaining and categorizing the challenges facing methodological approaches in explaining the phenomenon of social emergence, in three categories: realism, downward causality, and mechanism.

This critical study of the third book of Plantinga's trilogy on proper-function epistemology begins by denying that classical foundationalism proposes a deontic conception of justification. Nor is it subject to Gettier counterexamples, as, I show, Plantinga's fallibilism is and must be. Plantinga's central thesis is that there's no way of attacking the rationality of central Christian beliefs without attacking their truth. That, I argue, is not so on several grounds, e.g., because one can demand independent evidence (...) for the existence of the _sensus divinitatis and Holy Spirit, because of doctrinal disagreements, and because of the morally checkered character of "saved" Christians.

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.

The modern concept of science is rooted in a metaphysical option of materialist monism. The religious beliefs are inevitably founded on the pluralist concept of reality. Hence, the conflict is inevitable. Monism blames religion for producing illusions, while religion accuses the sciences of being epistemologically self-mutilated by their intrinsic reductionism. There exists a third realm of cognition, namely the growing bulk of knowledge. It is relatively independent of temporary fluctuations of "scientific standards" and "scientific methodologies". It is also independent (...) of the religious beliefs founded on some extraordinary, miraculous, "supranatural" events. The knowledge (a sufficiently accurate orientation in the real world) is present both in the highly civilized communities and in the so called "primitive" illiterate populations. Technical achievements confirm the essential accuracy of the knowledge and, at the same time, give some support to the foundations of teleological concepts and consequently to many of religious beliefs.

In this companion volume to Warrant: The Current Debate, Plantinga develops an original approach to the question of epistemic warrant; that is what turns true belief into knowledge. He argues that what is crucial to warrant is the proper functioning of one's cognitive faculties in the right kind of cognitive environment.

This little volume, using a combined approach of phenomenology, history, philosophy, and theology probes deeply into questions of belief and commitment. The book is valuable for scholars who possess the background and sensitivity to appreciate the three essays which constitute it. The first of these, "The Structure of Jewish Experience," takes up the epistemological problem of belief in a God who is present in history and who can consequently be the object of worship by modern man just as (...) he was thousands of years ago. The second essay, "The Challenge of Modern Secularity," deals with current theological issues, including the Subjectivist Reductionism, the "Death" of God, and faith as "immediacy after reflection." The third and most impassioned essay, "The Commanding Voice of Auschwitz," deals with themes which have been the preoccupation of Elie Wiesel, to whom the book is dedicated. There have not been many Jewish writers since the holocaust, who have been willing to write about their faith. Fackenheim speculates that it must be difficult to justify such faith to oneself in light of the fate of the Jews in recent history. In this book, and particularly in the last essay, the author attempts to justify such faith, and he does it intelligently and eloquently.--S. J. B. (shrink)

In its traditional form epistemology has always rested on the exclusive reality of the subject-object relationship. If one asks how the subject knows the object, one has in brief form the essence of theory of knowledge from Plato to Bergson; the differences between the many schools of philosophy can all be understood as variations on this theme. There are, first of all, differences in emphasis as to whether the subject or the object is the more real--as in rationalism and empiricism, (...) idealism and materialism, personalism and logical positivism. There are differences, secondly, as to the nature of the subject, which is variously regarded as pure consciousness, will to life, will to power, the scientific observer, or the intuitive knower. There are differences, thirdly, as to the nature of the object--whether it is material reality, thought in the mind of God or man, pantheistic spiritual substance, absolute and eternal mystical Being, or simply something which we cannot know in itself but upon which we project our ordered thought-categories of space, time, and causation. There are differences, finally, as to the relation between subject and object: whether the object is known through dialectical or analytical reasoning, scientific method, phenomenological insight into essence, or some form of direct intuition.

I begin by introducing the ideas of possible worlds, books on worlds, and essential properties. A possible world is a broadly logically possible state of affairs that is maximal. Furthermore, for any possible world W and proposition p, let the book on W be the set S of propositions such that p is a member of S if W entails p. Finally, an object x has property P essentially if and only if x has P and has it in every (...) world in which x exists. I use the above three concepts to give a sound argument for the conclusion that human persons are essentially immaterial. (shrink)

These essays, dating from the late 1960's to the present, 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 answers to these and other questions.

Can we speak and think about God? -- What is the question? -- Warranted belief in God -- The extended A/C model -- Faith -- Sealed upon our hearts -- Objections -- Defeaters? historical biblical criticism -- Defeaters? pluralism -- Defeaters? evil.

Chapter 6 is an attempt to show that the Theory of Worldbound Individuals —i.e. the theory that any object exists in exactly one possible world—is false, and that there's no good reason to deny that objects exist in more than one world. First, arguments that attempt to show that a denial of TWI entails a contradiction fail, and the so‐called Problem of Transworld Identity is no problem at all. Second, TWI should be rejected because it entails that all of an (...) object's properties are essential to it. The defender of TWI may attempt to defend his view by adopting Counterpart Theory. I conclude by arguing that the Counterpart Theory is both semantically and metaphysically inadequate. (shrink)

In Part I, I present two traditional arguments for the incompatibility of divine foreknowledge with human freedom; the first of these is clearly fallacious; but the second, the argument from the necessity of the past, is much stronger. In the second section I explain and partly endorse Ockham’s response to the second argument: that only propositions strictly about the past are accidentally necessary, and past propositions about God’s knowledge of the future are not strictly about the past. In the (...) class='Hi'>third part I point out some startling implications of Ockham’s way out; and finally in part IV I offer an account of accidental necessity according to which propositions about the past are accidentally necessary if and only if they are strictly about the past. (shrink)

I argue that each object has many essences. A property E is an essence of object x if and only if E is essential to x and in every possible world everything distinct from x has the complement of E essentially. I then elaborate on the nature of essences and examine the relationship between essences and proper names. My view is that John Stuart Mill was mistaken in his belief that proper names do not express properties. In fact, proper (...) names express essences and I make use of this fact in addressing the famous problem of Hesperus and Phosphorus. (shrink)

The others have: Paul Shorey, Plato's Ethics; David Sachs, A Fallacy in Plato's Republic; Raphael Demos, A Fallacy in Plato's Republic?; J. D. Mabbott, Is Plato's Republic Utilitarian?; G. Vlastos, Justice and Happiness in the Republic; F. M. Cornford, The Doctrine of Eros in Plato's Symposium; R. A. Markus, The Doctrine of Eros in Plato's Symposium; Glenn R.

Verdenius, Plato's Doctrines of Artistic Imitation. Obviously, the above listed articles will be welcome to those debating issues in Plato and to historians of twentieth-century philosophy. There are two difficulties, however. The print is too small in the body of the text and is nearly microscopic in the footnotes and diagrams. Reading thus becomes almost painful. Margins to the left, right, top and bottom of the pages are practically nonexistent. On occasion footnote material is misplaced--for example, the comment on Strang's article as originally published elsewhere should be on p. 184, not on p. 187, of Volume One. But a greater problem is the fact that almost all the articles on metaphysics and epistemology are by linguistic analysts. Vlastos in his introductory remarks admits as much: "Volume One is heavily weighted on the 'analytical' side." He reports the statement of an un-named advocate of conceptual analysis "that these [analytic] methods now enable us to understand Plato better than he was ever understood by anyone in history--better than by any of his own contemporaries, even better than by himself!" He disclaims such euphoria but insists "there is an element of truth in it after all" insofar as analytic tools can alert a student to ambiguity and its consequences in some of Plato's sentences. Hence, "if we come across such sentences in Plato, it would be plainly true to say that we can understand them better than he did and even to add that we can, therefore, understand him better, since we can see both what he meant to say and the logical liabilities of his incautious sentences." All this is true enough, but a warning still is in order. Linguistic analysts tend to read only some of Plato's dialogues and, even within them, to concentrate on some passages only. This is understandable in view of their interests and the capacity of the analytic technique. But that selectivity might lead them to believe that the Plato thus revealed is the complete and authentic Plato, which it is not. Hence, in reading and teaching Plato one must complement language- and concept-analysis with other approaches. Vlastos himself is aware of this necessity : [[sic]] "Once we have made full allowance for what modern semantics and logic can do to make Plato more intelligible and alive for us today, we should be quick to concede that borrowings from this quarter must be used with economy and discretion, and that continuing reliance on older linguistic and historical disciplines is as essential now as it has ever been in the past if the object of our inquiries is Plato himself, instead of some mock-up more pleasing to current taste." One could only wish that Vlastos had fostered that reliance on other disciplines by including articles of that sort among those he actually chose.--L. S. (shrink)

Vlastos himself is aware of this necessity : [[sic]] "Once we have made full allowance for what modern semantics and logic can do to make Plato more intelligible and alive for us today, we should be quick to concede that borrowings from this quarter must be used with economy and discretion, and that continuing reliance on older linguistic and historical disciplines is as essential now as it has ever been in the past if the object of our inquiries is Plato himself, instead of some mock-up more pleasing to current taste." One could only wish that Vlastos had fostered that reliance on other disciplines by including articles of that sort among those he actually chose.--L. S. (shrink)

Sets of contingent objects, perhaps, are as contingent as their members; but properties, propositions, numbers and states of affairs, it seems, are objects whose non-existence is quite impossible. If so, however, how are they related to God? Suppose God has a nature: a property he has essentially that includes each property essential to him. Does God have a nature? And if he does, is there a conflict between God's sovereignty and his having a nature? How is God related to such (...) abstract objects as properties and propositions? These are the questions I want to explore. - Introduction. (shrink)

Is belief in God epistemically justified? That's the question at the heart of this volume in the Great Debates in Philosophy series, with Alvin Plantinga and Michael Tooley each addressing this fundamental question with distinctive arguments from opposing perspectives. The first half of the book contains each philosopher's explanation of his particular view; the second half allows them to directly respond to each other's arguments, in a lively and engaging conversation Offers the reader a one of a kind, interactive (...) discussion Forms part of the acclaimed Great Debates in Philosophy series.

I took it that the definitions Swinburne quotes imply that all of a person's basic beliefs are rational; Swinburne demurs. It still seems to me that these definitions have this consequence. Let me briefly explain why. According to Swinburne, a person's evidence consists of his basic beliefs, weighted by his confidence in them. So presumably we are to think of S's evidence as the set of the beliefs he takes in the basic way, together with a sort of index indicating, (...) for each of those beliefs, his degree of confidence in that belief. Now it is clear, first, that different basic beliefs can be held with different degrees of confidence. I believe 2+1 = 3 more firmly than there are presently some large trees in my backyard, and I believe that second proposition more firmly than I played bridge last night. Nevertheless, I believe all three propositions; I don't just believe them probably. So, the set of my basic beliefs contains propositions, all of which I believe. Further, a belief of mine is ‘rendered probable by [my] evidence’, I take it, just if it is probable with respect to the set of my basic beliefs. But of course probability of 1 with respect to that set; the degree of confidence with which I hold those beliefs does not seem to be relevant. Hence my conclusion that on these definitions all of my basic beliefs are rational. Swinburne points out that some of my basic beliefs may be improbable with respect to the rest of my basic beliefs; these beliefs, then, might be thought irrational, at least if they are not held as firmly as those with respect to which they are improbable. But this seems to me an uninteresting sense of ‘irrational’. Many of my basic beliefs are improbable with respect to my other basic beliefs; they are none the worse for that. I now remember, as it seems to me, that in the second bridge hand last night I was dealt three aces, three jacks, and three deuces. This is unlikely on the rest of my basic beliefs. It is, nonetheless, not irrational in any useful sense; memory is an important and independent source of rational belief, a source such that its deliverances do not necessarily depend, for warrant or rationality, on their probability with respect to other basic beliefs. I believe the same goes for some of my Christian beliefs. They may be improbable with respect to other beliefs, basic or otherwise, that I hold; but that need be nothing whatever against them.

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.

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'.

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.

are properly basic for at least some believers in God; there are widely realized sets of conditions, I suggested, in which such propositions are indeed properly basic. And when I said that these beliefs are properly basic, I had in mind what Quinn calls the narrow conception of the basing relation.[1] I was taking it that a person S accepts a belief A on the basis of a belief B only if (roughly) S believes both A and B (...) and could correctly claim (on reflection) that B is part of his evidence for A. S's belief that there is an error in some argument against p will not typically be a belief on the basis of which he accepts p and will not be a part of his evidence for p. (shrink)

Alvin Plantinga over the decades has developed a particular theory of warrant that would allow certain beliefs to be warranted, even if one lacked propositional arguments or evidence for them. One such belief that Plantinga focuses on is belief in God. There have been, however, numerous objections both to Plantinga's theory of warrant and to the religious application that he makes of it. In this article I address an objection from both of these categories. I first (...) tackle an objection that attempts to show that proper function isn't a necessary condition for warrant. After tackling this, I move on to interact with the Pandora's Box Objection. This objection argues that Plantinga's epistemology is weakened by the fact that all sorts of serious religious beliefs could be warranted by using his system. (shrink)

Philip Quinn’s “On Finding the Foundations of Theism” is both challenging and important. Quinn proposes at least the following four theses: (a) my argument against the criteria of proper basicality proposed by classical foundationalism is unsuccessful, (b) the quasi-inductive method I suggest for arriving at criteria of proper basicality is defective, (c) even if belief in God is properly basic, it could without loss of justification be accepted on the basis of other propositions, and (d) belief in God (...) is probably not nowadays properly basic for intellectually sophisticated adults, There is much to be said about each of these four theses; I shall say just a bit about them. I take the fourth claim to be the most important and devote the most space to it. (shrink)

In this paper I propose an amendment to Chisholm's definition of individual essence. I then argue that a thing has more than one individual essence and that there is no reason to believe no one grasps anyone else's essence. The remainder of the paper is devoted to a refutation of existentialism, the view that the essence of an object X (along with propositions and states of affairs directly about x) is ontologically dependent upon x in the sense that it could (...) not have existed if x had not existed.

Kant says that it can be rational to accept propositions on the basis of non-epistemic or broadly practical considerations, even if those propositions include “transcendental ideas” of supersensible objects. He also worries, however, about how such ideas (of freedom, the soul, noumenal grounds, God, the kingdom of ends, and things-in-themselves generally) acquire genuine positive content in the absence of an appropriate connection to intuitional experience. How can we be sure that the ideas are not empty “thought-entities (Gedankendinge)”—that is, speculative fancies (...) that do not and perhaps even cannot have referents in reality? In this paper I argue for an account of the fundamental problem here (i.e. that it is based in a concern about whether or not the objects of such ideas are "really possible" in Kant's technical sense). I then critically evaluate Kant's three proposed solutions to the problem. The third one involves an appeal to the complicated doctrine of "symbolization" that becomes prominent in Kant's later works. -/- . (shrink)

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.

Two kinds of critical questions have been asked about the propriety or rightness of Christian beliefs. The first is the de facto question: is Christian belief true? The second is the de jure question: is it rational, or reasonable, or intellectually acceptable, or rationally justifiable? This second question is much harder to locate than you’d guess from looking at the literature. In “Perceiving God” William AIston suggests that the (or a) right question here is the question of “the practical (...) rationality,” construed as he construes it. I argue that the question is ambiguous: and one of the disambiguees is too easy to answer, while the other is such that its answer is really irrelevant to any sensible version of the de jure question. I conclude by venturing a suggestion as to what a sensible de jure question might be. (shrink)

The synopsis has been prepared by the Editor, with the author’s approval, from a handout provided by the author at the conference. The paper reflects on whether religious belief of a traditional Christian kind can be maintained consistently with accepting our modern scientific worldview. Many theologians, and also many scientists, (...) maintain that the idea of divine intervention is at odds with the framework of natural laws disclosed by science. The paper argues that this notion of a ”religion/science problem’ is misguided. When properly understood, neither the classical (Newtonian) picture of natural laws, nor the more recent quantum mechanical picture, rules out divine intervention. There is nothing in science, under either the old or the new picture, that conflicts with, or even calls in to question, special divine action, including miracles. (shrink)
