Traditional theists are, with few exceptions, global semantic realists about the interpretation of external world statement. Realism of this kind is treated by many as a shibboleth of traditional Christianity, a sine qua non of theological orthodoxy. Yet, this love affair between theists and semantic realism is a poor match. I suggest that everyone (theist or no) has compelling evidence drawn from everyday linguistic practice to reject a realist interpretation of most external world statements. But theists have further reason to (...) forswear this view, because those who insist on global semantic realism open themselves to the charge of hubris of a theologically inappropriate kind. If the arguments in this paper are sound, then neither God nor any of us have reason to apply a realist interpretation to all or even most statements about the external world. (shrink)

Moral error theory claims that no moral sentence is (nonvacuously) true. Atheism claims that the existence of evil in the world is incompatible with, or makes improbable, the existence of God. Is moral error theory compatible with atheism? This paper defends the thesis that it is compatible against criticisms by Nicholas Sturgeon.

The expression conditional fallacy identifies a family of arguments deemed to entail odd and false consequences for notions defined in terms of counterfactuals. The antirealist notion of truth is typically defined in terms of what a rational enquirer or a community of rational enquirers would believe if they were suitably informed. This notion is deemed to entail, via the conditional fallacy, odd and false propositions, for example that there necessarily exists a rational enquirer. If these consequences do indeed follow from (...) the antirealist notion of truth, alethic antirealism should probably be rejected. In this paper we analyse the conditional fallacy from a semantic (i.e. model-theoretic) point of view. This allows us to identify with precision the philosophical commitments that ground the validity of this type of argument. We show that the conditional fallacy arguments against alethic antirealism are valid only if controversial metaphysical assumptions are accepted. We suggest that the antirealist is not committed to the conditional fallacy because she is not committed to some of these assumptions. (shrink)

In this paper, I argue that there are universals. I begin (Sect. 1) by proposing a sufficient condition for a thing’s being a universal. I then argue (Sect. 2) that some truths exist necessarily. Finally, I argue (Sects. 3 and 4) that these truths are structured entities having constituents that meet the proposed sufficient condition for being universals.

The concern of this paper is not with the truth of any particular realist or anti-realist view, but rather with determining what it is to be a realist or anti-realist in the first place. While much skepticism has been voiced in recent years about the viability of such a project, my goal is to articulate interesting and informative conditions whereby any view in any domain of experience can count as either a realist or an anti-realist position.

Brogaard and Salerno (2005, Nous, 39, 123–139) have argued that antirealism resting on a counterfactual analysis of truth is flawed because it commits a conditional fallacy by entailing the absurdity that there is necessarily an epistemic agent. Brogaard and Salerno's argument relies on a formal proof built upon the criticism of two parallel proofs given by Plantinga (1982, "Proceedings and Addresses of the American Philosophical Association", 56, 47–70) and Rea (2000, "Nous," 34, 291–301). If this argument were conclusive, antirealism resting (...) on a counterfactual analysis of truth should probably be abandoned. I argue however that the antirealist is not committed to a controversial reading of counterfactuals presupposed in Brogaard and Salerno's proof, and that the antirealist can in principle adopt an alternative reading that makes this proof invalid. My conclusion is that no reductio of antirealism resting on a counterfactual analysis of truth has yet been provided. (shrink)

In his presidential address to the APA, Alvin Plantinga argues that the only sensible way to be an anti-realist is to be a theist. Anti-realism (AR) in this context is the epistemic analysis of truth that says, "(AR) necessarily, a statement is true if and only if it would be believed by an ideally [or sufficiently] rational agent/community in ideal [or sufficiently good] epistemic circumstances." Plantinga demonstrates, with modest modal resources, that AR entails that necessarily, ideal epistemic circumstances obtain. As (...) it is a contingent matter whether ideal epistemic circumstances obtain, Plantinga concludes that an anti-realist should be a theist. In this paper, we show that counterfactual analyses of truth as epistemic are instances of a more general problem of philosophical analysis. More specifically, without a radical revision of the logic, counterfactual analyses of truth as epistemic cannot avoid perpetrating some version of the conditional fallacy. Even so, we argue, anti-realists are not committed to the necessary existence of ideal epistemic circumstances and therefore need not be theists. (shrink)

This book takes purism about knowledge as the default position and defends it from the challenges of pragmatic encroachment. The book is divided into two parts, a negative and a positive one. The negative part critically examines existing purist strategies in response to pragmatic encroachment. The positive part provides a new theory of how practical factors can systematically influence our confidence and explores some implications of such influence.

There are some arguments supporting the pessimistic meta-induction, coming from the direction of quantum theory (A. Kukla and J. Walmsley), from the direction of Laudan’s list with successful but false theories, and from the specific direction of the phlogiston theory (whom Kukla Walmsley, and S. Psillos consider to be false). Against these arguments we believe we can successfully oppose, in the first case the interactive quantum realism of I. Niiniluoto, in the second case the realism of the theoretical theoretical constituents (...) responsible for the empirical success of the theories of S. Psillos, and in the third case the analysis of the phlogiston theory done by V. Verronen, R. Vihalemm and E. McMullin (who suggested that this theory was simultaneously insufficiently mature and approximately true). Our conclusion does not necessary prove that the perspective of the scientific realism is true, but rather that the pessimistic meta-induction attack against it proves to be unconvincing. (shrink)

This study intends to show that the question whether faith can be justified without proofs can be resolved by importing ideas from Kierkegaard’s and Plantinga’s affirmative take on the matter. There is a deep similarity between the way they understand belief in God and belief in Christianity: for both the first is considered universal human knowledge and the second seen as a gift from God. Against the charge that such an understanding is irrational Plantinga offers an externalist epistemological model which (...) allows those beliefs to be warranted. The authors also share the modern idea that there is an objective truth, combining it with the postmodern stance that no method exists which would guarantee access to it. A specific contribution on Kierkegaard’s part to the understanding of the rationality of transitions toward a Christian stage of existence is to show in detail the way in which such transitions are mediated through inwardnes - a perspective akin to Michael Polanyi’s scientific epistemology. One can see in both authors not only a deep commonality of ideas, but also a remarkable way in which their understandings augment each other. Whereas Plantinga’s inquiry contributes to the rational plausibility of a “Justified Faith without Reasons” project, Kierkegaard’s venture balances such a logical-analytic effort with a deep existential inquiry.

Most philosophers of religion subscribe to some variety of religious realism: they believe that religious statements aim at capturing a mind-independent reality and are true precisely if they successfully do so. Curiously, most religious realists also believe that at least some of our religious beliefs are rationally justified. In this paper, I argue that these positions are actually at odds with each other. Religious realists should rather be religious skeptics. I first argue that realism always implies the possibility of our (...) beliefs being false. Then, I develop a Copernican argument to show that we have no reason to believe that we are in an epistemically privileged position where we could be confident that our particular belief is justified while all competing beliefs are not. This seems impossible for two reasons: (a) From a probabilistic point of view (adopting a principle of mediocrity), it is highly unlikely that current humans have the maximum of epistemic capacities possible. Rather, our ability to understand reality is limited, so we should expect at least some parts of religious reality to remain unknown to us. (b) From a deep-time perspective, humanity has not pondered religious questions for long. We are probably still in the early stages of our cognitive evolution, and so we should treat our religious beliefs as provisional and open to revision. (shrink)

In this chapter, I make the case for platonic realism, the thesis that there are properties that lack spatial locations. After criticizing the one-over-many argument for realism and Lewis's argument for realism, I endorse a modal argument that derives the existence of platonic properties from considerations involving necessary truth. I then defend this argument from various objections. Finally, I argue that epistemic considerations and considerations of parsimony favor a weak form of platonic realism on which there are platonic properties, but (...) each property could have had an instance, and would have been located in its instances if it had any.

This volume announces a new era in the philosophy of God. Many of its contributions work to create stronger links between the philosophy of God, on the one hand, and mathematics or metamathematics, on the other hand. It is about not only the possibilities of applying mathematics or metamathematics to questions about God, but also the reverse question: Does the philosophy of God have anything to offer mathematics or metamathematics? The remaining contributions tackle stereotypes in the philosophy of religion. The (...) volume includes 35 contributions. It is divided into nine parts: 1. Who Created the Concept of God; 2. Omniscience, Omnipotence, Timelessness and Spacelessness of God; 3. God and Perfect Goodness, Perfect Beauty, Perfect Freedom; 4. God, Fundamentality and Creation of All Else; 5. Simplicity and Ineffability of God; 6. God, Necessity and Abstract Objects; 7. God, Infinity, and Pascal's Wager; 8. God and (Meta-)Mathematics; and 9. God and Mind. (shrink)

Moral realism and ethical naturalism are both highly attractive ethical positions but historically they have often been thought to be irreconcilable. Since the late 1980s defenders of Cornell Realism have argued that the two positions can consistently be combined. They make three constitutive claims: (i) Moral properties are natural kind properties that (ii) are identical to (or supervene) on descriptive functional properties, which (iii) causally regulate our use of moral terms. We offer new arguments against the feasibility of Cornell realism (...) and then show that there is a way to be a naturalistic realist that avoids internal inconsistency and uniquely provides for moral normativity.

A strength of liberal political institutions is their ability to accommodate pluralism, both allowing divergent comprehensive doctrines as well as constructing the common ground necessary for diverse people to live together. A pressing question is how far such pluralism extends. Which comprehensive doctrines are simply beyond the pale and need not be accommodated by a political consensus? Rawls attempted to keep the boundaries of reasonable disagreement quite broad by infamously denying that political liberalism need make reference to the concept of (...) truth, a claim that has been criticized by Joseph Raz, Joshua Cohen, and David Estlund. In this paper, we argue that these criticisms fail due to the fact that political liberalism can remain non-committal on the nature of truth, leaving the concept of truth in the domain of comprehensive doctrines while still avoiding the issues raised by Raz, Cohen, and Estlund. Further substantiating this point is the fact that Rawls would, and should, include parties in the overlapping consensus whose views on truth may be incoherent. Once it is seen that political liberalism allows such incoherence to reasonable parties, it is clear that the inclusion of truth and the requirement of coherence urged by Raz, Cohen, and Estlund requires more of reasonable people than is necessary for a political consensus.

This paper argues against Davidson’s claim that there is no distinction between conceptual schemes and their content and derives the implications for the debate on realism and antirealism. Starting from a semantic conception of realism, I discuss Davidson’s argument against conceptual schemes and untranslatable languages. I argue that the idea of an untranslatable language is consistent since language attribution is essentially normative. Untranslatable languages are metaphysically possible, but epistemically unrecognizable. This leads to a Berkeleyan argument against antirealism: if antirealism is (...) conceived of as dependence from a total language (instead of merely some actual language), the distinction between realism and antirealism vanishes: antirealism is realism.

Divine necessity is the thesis that God must exist. In this paper, I give a brief survey of what the thesis is more exactly, the main arguments for it, and the main arguments against it.

Many have thought that it is impossible to rationally persuade an external world skeptic that we have knowledge of the external world. This paper aims to show how this could be done. I argue, while appealing only to premises that a skeptic could accept, that it is not rational to believe external world skepticism, because doing so commits one to more extreme forms of skepticism in a way that is self-undermining. In particular, the external world skeptic is ultimately committed to (...) believing a proposition P while believing that she shouldn’t believe P, an irrational combination of beliefs. Suspending judgment on skepticism is also problematic, for similar reasons; and, I argue, rational dilemmas are not possible; so, we should believe that skepticism is false. (shrink)

Divine conceptualism takes all abstract objects to be propositions in the mind of God. I focus here on necessary propositions and contemporary claims that the laws of logic, understood as necessarily true propositions, provide us with an epistemic bridge to theological predication—specifically, to the claim that God exists. I argue that when contemporary versions of DC say ‘G/god’ they merely rename the notion of necessary truth, and fail to refer to God. Given that God is incomprehensible, epistemic access to the (...) state of propositions in the mind of God is extremely limited. (shrink)

There are various entities which, if they exist, would be candidates for necessary beings: God, propositions, relations, properties, states of affairs, possible worlds, and numbers, among others. Note that the first entity in this list is a concrete entity , while the rest are abstract entities. Many interesting philosophical questions arise when one inquires about necessary beings: What makes it the case that they exist necessarily? Is there a grounding for their necessary existence? Do some of them depend on others? (...) If so, how might one understand the dependence relation? (shrink)

My goal in this paper is to show that naturalists cannot reasonably endorse moral realism. My argument will come in two parts. The first part aims to show that any plausible and naturalistically acceptable argument in favor of belief in objective moral properties will appeal in part to simplicity considerations (broadly construed)—and this regardless of whether moral properties are reducible to non-moral properties. The second part argues for the conclusion that appeals to simplicity justify belief in moral properties only if (...) either those properties are not objective or something like theism is true. Thus, if my argument is sound, naturalists can reasonably accept moral realism only if they are prepared to accept something like theism. But, as will become clear, naturalists can reasonably accept theism or something like it only if belief in some such doctrine is justified by the methods of science. For present purposes, I’ll assume (what I think virtually every naturalist will grant) that belief in theism and relevantly similar doctrines is not justified by the methods of science. Thus, I will conclude that naturalists cannot reasonably accept moral realism. (shrink)

The chapter distinguishes between a weak and a strong form of ontological naturalism. Strong ontological naturalism is the view that all truths can be deduced, at least in principle, from truths about physical entities at the lowest level of organization, for example, truths about the elementary particles and forces. Weak ontological naturalism is the view that only physical properties can be causally efficacious. Strong ontological naturalism entails weak ontological naturalism but not vice versa. I then argue that the existence of (...) a truth property is consistent with weak ontological naturalism, as truth is not causally efficacious. After considering several prominent theories of truth, I argue that the only theories of truth that are consistent with strong ontological naturalism are deflationary doctrines that deny that there is a substantial truth property but these theories are not suitable adjoints to strong naturalism, as folks with strong naturalist inclinations normally want to posit the existence of substantial natural properties. Yet if the truth property itself is insubstantial, so are claims about the existence of substantial natural properties. I conclude by arguing that the result that there cannot be a naturalistic theory of truth is unsurprising, as there are independent reasons for thinking that the basic semantic notions must be treated an irreducible, primitive properties.

In this article, I reply to Juli Eflin's “Epistemic Presuppositions and Their Consequences.” I query Eflin's construal of the aims, scope and method of traditional epistemology, and go on to evaluate several of the central characteristics of Eflin's positive account – pluralistic virtue epistemology.

Moral relativism is an attractive position, but also one that it is difficult to formulate. In this paper, we propose an alternative way of formulating moral relativism that locates the relativity of morality in the property that makes moral claims true. Such an approach, we believe, has significant advantages over other possible ways of formulating moral relativism. We conclude by considering a few problems such a position might face.

Adherents of traditional western Theism have espoused CONJUNCTION: God is essentially perfectly good and God is thankworthy for the good acts he performs. But suppose that (i) God’s essential perfect goodness prevents his good acts from being free, and that (ii) God is not thankworthy for an act that wasn’t freely performed. Together these entail the denial of CONJUNCTION. The most natural strategy for defenders of CONJUNCTION is to deny (i). We develop an argument for (i), and then identify two (...) ways for the defender of CONJUNCTION to respond. Next we turn to a considerably different, rather less obvious route toward defending CONJUNCTION that is compatible with (i)—one which instead denies (ii). Here too we identify two ways for the defender of CONJUNCTION to proceed, yielding a total of four ways for the theist to respond. Because the last of these represents an important and underappreciated alternative for the theist, we devote the second half of the paper to developing and defending it. We argue that divine responsibility is sufficient for divine thankworthiness and consistent with the absence of divine freedom. We do this while insisting on the view that both freedom and responsibility are incompatible with causal determinism. (shrink)

An "overview article" that (a) clarifies the nature of theological anti-realism and how that thesis should be formulated, and (b) negatively assesses some of the most common arguments for being a theological anti-realist.

In this paper I consider metaphysical positions which I label as ‘perspectival’. A perspectivalist believes that some portion of reality cannot extend beyond what an appropriately characterised investigator or investigators can (in some sense) reveal about it. So a perspectivalist will be drawn to claim that a portion of reality is, in some sense, knowable. Many such positions appear to founder on the paradox of knowability. I aim to offer a solution to that paradox which can be adopted by any (...) perspectivalist, which involves no restriction on the claim of knowability and which allows certain sentences to be unknowable. The solution hinges on recognising that what is meant by ‘knowable’ will vary from one type of proposition to another and thus that characterising the modality involved in the notion in terms of possible worlds will be impossible. I thus offer a subjunctive conditional reading of that modality, a reading which, I claim, has the virtues just recounted. (shrink)

Until now, antirealists have offered sketches of a theory of truth, at best. In this paper, we present a probabilist account of antirealist truth in some formal detail, and we assess its ability to deal with the problems that are standardly taken to beset antirealism.

Philosophers have often attempted to use counterfactual conditionals to analyze probability. This article focuses on counterfactual analyzes of epistemic probability by Alvin Plantinga and Peter van Inwagen. I argue that a certain type of counterfactual situation creates problems for these analyses. I then argue that Plantinga's intuition about the role of warrant in epistemic probability is mistaken. Both van Inwagen's and Plantinga's intuitions about epistemic probability are flawed.

This article examines a somewhat neglected argument for the existence of God which appeals to the divine perspective as a way of reconciling the conflicting claims of realism and anti-realism. Six representative examples are set out (Berkeley, Ferrier, T. H. Green, Josiah Royce, Gordon Clark and Michael Dummett), reasons are considered why this argument has received less attention than it might, and a brief sketch given of the most promising way in which it might be developed.

The subject of this thesis is physicalism, understood not as some particular doctrine pertaining narrowly to the philosophy of mind, but rather as a quite general metaphysical claim to the effect that everything is, or is fundamentally, physical. Thus physicalism explicates the thought that in some sense physics is the basic science. The aim of the thesis is to defend a particular brand of physicalism, which I call eliminative type physicalism. It claims, roughly, that every property is a physical property, (...) a property mentioned in the laws of physics, and hence that any putative property not identifiable with a physical property must be eliminated from our ontology. Eliminative type physicalism is apt to face three objections, and so my thesis, like Caesar's Gaul, falls into three parts. In the first, I argue against the idea that there are tenable positions, both physicalist and non-physicalist, alternative to eliminative type physicalism. I argue that each of these positions token physicalism (Fodor, middle Putnam), supervenience physicalism (Lewis, Horgan) and and a non-physicalist view I call pluralism (Goodman, late Putnam) is defective. In the second part, responding to the objection that there is just no reason to be a physicalist, I develop a positive argument for eliminative type physicalism, an argument resting upon a strong version of the explanatory test for reality according to which only explanatorily indispensable properties can justifiably be said to exist. In the third and final part, I argue, against the charge that eliminative type physicalism cannot accommodate what I call phenomenal properties (qualia, raw feels etc.), that there is no good reason to deny, and one good reason to affirm, that phenomenal properties just are physical properties. (shrink)

I propose a taxonomy of arguments for the existence of God and survey those categories of arguments I identify as nontraditional. I conclude with two general observations about theistic arguments, followed by suggestions for going forward.

In this paper I intend to discuss difficulties which face Hilary Putnam’s internal realism, difficulties which involve issues in semantics. I hope to show that Putnam has not presented a viable theory of truth. Putnam wishes to avoid relativism, which he claims is incoherent. My argument against Putnam’s theory of truth will be that Putnam has avoided relativism at only a very superficial level. On a deeper analysis we will see that Putnam has in fact not avoided relativism.Putnam has abandoned (...) the correspondence theory of truth since he can make no sense of the claim that our words, thoughts, images, sensations, etc. correspond to external objects. Considerations of human psychology (1983a, p.viii), as well as problems concerning reference (1981; 1983a, pp.vii-xviii; 1983b), have led Putnam to adopt the view that truth must be analyzed in terms of justification.

Global metaphysical antirealism (or “antirealism”) is often thought to entail that the identity of each and every concrete entity in our world ultimately depends on us—on our adoption of certain social and linguistic conventions, for instance, or on our use of certain conceptual schemes. Drawing on the middle‐period works of Maurice Merleau‐Ponty, I contend that metaphysical antirealism entails nothing of the sort. For Merleau‐Ponty, I argue, entities do not ultimately owe their identities to us, even though—as he puts it—their “articulations (...) are the very ones of our existence.” Once this is recognised, I maintain, certain interpretations of phenomenology are revealed to be caricatures and certain general objections to antirealism lose their force.

In this paper Modern Essentialism is used to solve a problem of individuation of spacetime points in General Relativity that has been raised by a New Leibnizian Argument against spacetime substantivalism, elaborated by Earman and Norton. An earlier essentialistic solution, proposed by Maudlin, is criticized as being against both the spirit of metrical essentialism and the fundamental principles of General Relativity. I argue for a modified essentialistic account of spacetime points that avoids those obstacles.

This paper sets out issues in the realist/antirealist debate in philosophy of religion. These include the existence of God and the meaning of prayer. The paper describes motivations for antirealism in religion such as the recognition of conflicting religious claims and a desire for tolerance. It explores instrumentalism and reductionism as possible antirealist strategies. Parallels between the debate in religion and the corresponding debate in philosophy of science are used to inform the discussion in the religious sphere. Shared aspects of (...) science and religion feature in a pragmatic argument suggesting that the advantages of realism outweigh those of antirealism for religion. (shrink)

The thesis includes six essays, each corresponding to a chapter, which have the target of widening the discussion on the limits of knowability through the consideration of some general problematics and the discussion of specific topics. The work is composed of two parts, each of three chapters. In the first part, the discussion is focused on a perspective proper of the philosophy of language. In particular, I consider the discussion on the limits of knowability from the point of view of (...) the debate between semantic realism and antirealism. The second part of the thesis is focused on the discussion on the limits of knowability from a perspective more strictly epistemological and proper of the philosophy of science. (shrink)

Em Warranted Christian Belief (2000), Alvin Plantinga (1932-) desenvolve sua Epistemologia Reformada (Calvinista), com o objetivo de oferecer aval (warrant) para a crença teísta (professada pelas Religiões Abraâmicas: Judaísmo, Cristianismo e Islam) e para a crença cristã clássica (uma crença cristã ecumênica aceita pelos Apóstolos de Cristo, os cristãos primitivos, os pais da Igreja, os ortodoxos, os católicos, os protestantes (os luteranos, os reformados e os arminianos) e os anabatistas). Todavia, o mais natural, que poderíamos esperar de uma Epistemologia Reformada, (...) seria uma epistemologia dedicada às crenças da Cosmovisão Reformada.
