The dissertation involves an examination of recent work in Social Epistemology. In particular, I am concerned with the question of how one's social position could affect judgments regarding evidence and confirmation. To answer this question I undertake an investigation of feminist epistemology and philosophy of science. Feminist epistemologists have raised criticisms of the traditional analysis of knowledge by arguing against the primacy of the individual and for a more thorough-going analysis of the community in accounts of knowledge. This shift, (...) in my view, is an important contribution toward a more complete theory of knowledge. Yet feminist epistemology is a controversial contributor to the area of social epistemology generally construed. Thus, in the first chapter I offer a defense of the contributions of feminist epistemology to analytic philosophy, against its various critics. ;In Chapters Two and Three I examine feminists' reliance on Naturalistic models of theory-choice such as Quinean Holism or the later Wittgenstein's Social Constructivism. I argue that the reliance on these models is a tactical mistake for feminists since these models are based on problematic accounts of meaning and truth. Alternatively, I advocate the adoption of a realist meaning theory along the lines proposed by Katz, as well as a rationalized epistemology in the service of explaining deductive and inductive inference. My argument involves showing how realism and rationalism entail the kind of strong program of justification and rational censure which is required if feminists want to successfully condemn existing biased practices. ;Consequently, I propose a reformulation of the distinction between a context of discovery and context of justification. My reformulation differs from the past positivist distinction in that "discovery" rather than being wholly random and subjective, is instead reflective of patterns of social experience. "Justification" is conceived of as more sensitive to the epistemic privilege of varying social standpoints. However, a separation is still maintained between how one comes to arrive at a belief and the methods for justifying that belief. My conclusion is that a partnership between rationalized epistemology and feminist theory can provide rich possibilities for both disciplines. (shrink)

There are three major theses in Plantinga’s latest version of his evolutionary argument against naturalism. (1) Given materialism, the conditional probability of the reliability of human cognitive mechanisms produced by evolution is low; (2) the same conditional probability given reductive or non-reductive materialism is still low; (3) the most popular naturalistic theories of content and truth are not admissible for naturalism. I argue that Plantinga’s argument for (1) presupposes an anti-materialistic conception of content, and it therefore (...) begs the question against materialism. To argue for (2), Plantinga claims that the adaptiveness of a belief is indifferent to its truth. I argue that this claim is unsupported unless it again assumes an anti-materialistic conception of content and truth. I further argue that Plantinga’s argument for (3) is not successful either, because an improved version of teleosemantics can meet his criticisms. Moreover, this version of teleosemantics implies that the truth of a belief is (probabilistically) positively related to its adaptiveness, at least for simple beliefs about physical objects in human environments. This directly challenges Plantinga’s claim that adaptiveness is indifferent to truth. (shrink)

Alvin Plantinga has famously argued that metaphysical naturalism is self-defeating, and cannot be rationally accepted. I distinguish between two different ways of understanding this argument, which I call the "probabilistic inference conception", and the "process characteristic conception". I argue that the former is what critics of the argument usually presuppose, whereas most critical responses fail when one assumes the latter conception. To illustrate this, I examine three standard objections to Plantinga's evolutionary argument against naturalism: the Perspiration (...) Objection, the Tu Quoque Objection, and the "Why Can't the Naturalist Just Add a Little Something?" Objection. I show that Plantinga's own responses to these objections fail, and propose counterexamples to his first two principles of defeat. I then go on to construct more adequate responses to these objections, using the distinctions I develop in the first part of the paper. (shrink)

Resumen Recientemente la ciencia cognitiva de la religión ha permitido desarrollar argumentos evolutivos desacreditadores, los cuales buscan poner en entredicho no solo la racionalidad sino la verdad del teísmo. Dado que hay dos formas de concebir la racionalidad y la justificación epistémicas, a saber, la internalista y la externalista, cabe preguntarse ¿de qué modo tales argumentos afectan al teísmo? El objetivo de este artículo es responder a esta cuestión mediante una reconstrucción y evaluación de tres argumentos evolutivos desacreditadores subproductistas contra (...) la racionalidad del teísmo que Dennett sostendría. Sostendré que solo uno de los tres argumentos de Dennett es posiblemente válido. igualmente, mostraré que el argumento adicional del sesgo cognitivo es probablemente exitoso en socavar la justificación internalista y externalista del teísmo. Finalmente, mostraré que estos argumentos evolutivos desacreditadores pueden ser invalidados indirectamente a partir del argumento evolutivo desacreditador en contra del naturalismo desarrollado por Plantinga, al cual se le puede contraponer el argumento lógico cancelador de la epistemología reformada.Recently, the cognitive science of religion has allowed the development of evolutionary debunking arguments, which seek to challenge not only rationality but the truth of theism. Since there are two ways of conceiving epistemic rationality and justification, viz., the internalist and the externalist, one may wonder ¿how such arguments affect theism? The purpose of this article is to answer this question through a reconstruction and evaluation of three evolutionary debunking arguments against the rationality of theism that Dennett would hold. I will argue that only one of the three Dennett's evolutionary debunking arguments is possibly valid. I will also show that the argument of cognitive bias is probably successful in undermining both the internalist and externalist justification of theism, under certain conditions. Finally, I will show that this arguments can be indirectly disproved from evolutionary argument against naturalism developped by Plantinga, argument to which one can counterpose logical defeater argument against the reformed epistemology.

A particular belief of a person is basic just in case it is epistemically justified and it owes its justification to something other than her other beliefs or the interrelations of their contents; a person’s belief is nonbasic just in case it is epistemically justified but not basic. Traditional Foundationalism says that, first, if a human being has a nonbasic belief, then, at bottom, it owes its justification to at least one basic belief, and second, there are basic beliefs. Call (...) the second thesis Minimal Foundationalism. In this essay, we assess three arguments against Minimal Foundationalism which we find in recent work of Peter Klein and Ernest Sosa. (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.

Albert Casullo (2000, 2003) and Shane Oakley (2011) argue that dilemma arguments against epistemic naturalism, such as those offered by Laurence BonJour (1998) and Harvey Siegel (1984), are such that, whatever strength they have against naturalism applies equally to moderate rationalist accounts of a priori justification. They conclude that dilemma arguments are, therefore, insufficient for establishing an advantage for moderate rationalism over naturalized epistemology. I argue that both Casullo's and Oakley's criticisms depend on an (...) illicit assumption, namely, that dilemma arguments presuppose a meta-justificatory demand that naturalists provide non-circular support for their basic sources of evidence. I argue that this assumption is not necessary for the force of dilemma arguments, and I construct a version that avoids this misreading. I conclude that, although there remain strategies for responding to dilemma arguments, they constitute a challenge naturalists must take seriously. (shrink)

Specialists often maintain that Menger has been strongly influenced by Aristotle’s thought ideas.This paper shows that although using Aristotle’s categories and general framework there are some issues in which Menger’s conclusions differs from Aristotle’s.This hint out that Menger’s knowledge of Aristotle’s ideas was not sufficiently deep and precise so as to completely capture its very spirit.Section two lays out the differences between Menger’s conception of theoretical science applied to economics and Aristotle’s conception of economics as a practical science.Section three (...) maintains that the Mengerian claim about the methodological absurdity of empirically testing the conclusions of exact research is not genuinely Aristotelian.Section four deals with the issue of Menger’s concept of organic social institutions showing its differences visà- vis an Aristotelian position.Les spécialistes soutiennent souvent que Menger a été fortement influencé par la pensée d’Aristote.Cet article montre que, bien qu’empruntant les catégories et la structure générale d’Aristote, certaines des conclusions de Menger diffèrent de celles d’Aristote.L’article suggère que la connaissance qu’avait Menger des idées d’Aristote n’était pas suffisamment approfondie et précise pour en appréhender le sens plein.La section deux présente les différences entre la conception de la science théorique présente dans l’économique de Menger et la conception aristotélicienne de l’économie comme une science pratique.La troisième section soutient que l’argument de Menger au sujet de l’absurdité méthodologique des tests empiriques des conclusions de la recherche exacte n’est pas réellement aristotélicien. La section quatre aborde la question des institutions sociales organiques chez Menger et montre ses différences vis-à-vis de la position aristotélicienne. (shrink)

In this essay, we put forth a novel solution to Plantinga’s Evolutionary Argument Against Naturalism, utilizing recent work done by Duncan Pritchard on radical skepticism. Key to the success of Plantinga’s argument is the doubting of the reliability of one’s cognitive faculties. We argue (viz. Pritchard and Wittgenstein) that the reliability of one’s cognitive faculties constitutes a hinge commitment, thus is exempt from rational evaluation. In turn, the naturalist who endorses hinge epistemology can deny the key premise in (...) Plantinga’s argument and avoid the dilemma posed on belief in the conjunction of naturalism and evolution.

Experimental philosophers have challenged friends of the expertise defense to show that the intuitive judgments of professional philosophers are different from the intuitive judgments of nonphilosophers, and the intuitive judgments of professional philosophers are better than the intuitive judgments of nonphilosophers, in ways that are relevant to the truth or falsity of such judgments. Friends of the expertise defense have responded by arguing that the burden of proof lies with experimental philosophers. This article sketches three arguments which show (...) that both and are probably false. If its arguments are cogent, then shifting the burden of proof is a futile move, since philosophical training makes no difference so far as making intuitive judgments in response to hypothetical cases is concerned.

Alvin Plantinga’s evolutionary argument against naturalism (EAAN) claims that if both naturalism (N) and evolutionary theory (E) are true, then all our beliefs are unreliable (premiss 1). Consequently, given N&E, the belief in N&E is unreliable (premiss 2) and N&E is self-defeating (conclusion). The empirical verification argument against naturalism (EVAAN) is more cautious and improves EAAN by withstanding a rejoinder of the evolutionary naturalist to premiss 1. EVAAN claims that non-abstract beliefs that are not empirically (...) verifiable are unreliable, given N&E (premiss 1a). This anticipates the evolutionary naturalist’s claim that empirical verifications play a crucial role in peer assessments and sexual selection of intelligence, and that, therefore, N&E makes empirically verifiable beliefs often reliable (premiss-1 rejoinder). However, even then it can be argued that the belief in N&E is unreliable, given N&E (premiss 2), because N&E is neither abstract, nor empirically verifiable (premiss 1b). EVAAN distinguishes reliably verifiable intelligence from metaphysical intelligence and claims that, if N&E is true, humans are lacking metaphysical intelligence. This paper also contains an argument against EAAN, by supporting the premiss-1 rejoinder. (shrink)

In this article I introduce constitutive norm accounts of assertion, and then give three arguments for giving up on the constitutive norm project. First I begin with an updated version of MacFarlane’s Boogling argument. My second argument is that the ‘overriding response’ that constitutive norm theorists offer to putative counterexamples is unpersuasive and dialectically risky. Third and finally, I suggest that constitutive norm theorists, in appealing to the analogy of games, actually undermine their case that they can make (...) sense of assertions that fail to follow their putative constitutive norm. These considerations, I suggest, together show that the constitutive norm project founders not because any single norm is not descriptively correct of our assertion practices, but rather, because giving a constitutive norm as the definition of assertion alone is insufficient.

Some mathematicians and philosophers contend that set theory plays a foundational role in mathematics. However, the development of category theory during the second half of the twentieth century has encouraged the view that this theory can provide a structuralist alternative to set-theoretical foundations. Against this tendency, criticisms have been made that category theory depends on set-theoretical notions and, because of this, category theory fails to show that set-theoretical foundations are dispensable. The goal of this paper is to show that (...) these criticisms are misguided by arguing that category theory is entirely autonomous from set theory. (shrink)

In this article, I critically assess Peter van Inwagen’s rejection of C. S. Lewis’s argument against Naturalism. Van Inwagen argues that Lewis (1960) errs on two fronts. First, he falsely assumes that Naturalism implies Spinozism: that the only way the world could be is the way it is. Second, the central premise of Lewis’s argument is asserted without proof. I argue that van Inwagen is mistaken on both counts.

Some philosophers identify the meaning of a work of art with what the artist intended the work to mean. Other philosophers think that although an artist’s intentions don’t fully determine a work’s meaning, they are a partial determinate of it. Last, there are philosophers who think that an artist’s intentions have no bearing on a work’s meaning. This paper is an examination of several arguments for the last of these three positions. In particular, it is a critical examination (...) of three arguments advanced by Monroe Beardsley in his earlier writings in aesthetics. (shrink)

This essay offers some fairly extensive objections to the critique of Bhaskar’s use of transcendental arguments found in chapter four of Tuukka Kaidesoja’s Naturalizing Critical Realist Social Ontology. The essay has three sections that correspond to three sets of objections, each of which centres around a certain topic in Kaidesoja’s critique. The first concerns Kaidesoja’s appeal to the connection between transcendental arguments and Kant’s transcendental idealism to criticize Bhaskar. The second concerns Kaidesoja’s problematization of a posteriori (...) premises in Bhaskar’s transcendental arguments. The third concerns Kaidesoja’s rejection of the prospect of ‘naturalized transcendental arguments’ and the non-transcendental ‘naturalistic arguments’ he proposes as an alternative. The overall aim of this essay is not just to defend Bhaskar’s naturalized transcendentalism against Kaidesoja’s metaphilosophical naturalism but also to help counter the association of transcendental philosophy with anti-naturalistic apriorism, foundationalism, idealism, and infalliblism frequently voiced by antitranscendental philosophers.

There are three basic skeptical arguments against developing a scientific theory of consciousness: theory cannot capture a first person perspective; consciousness is causally inert with respect to explaining cognition; and the notion "consciousness" is too vague to be a natural kind term. Although I am sympathetic to naturalists' counter-arguments, I also believe that most of the accounts given so far of how explaining consciousness would fit into science are incorrect. In this essay, I indicate errors my (...) colleagues on both sides of the fence make in thinking about this issue, as well as outline data relevant to distinguishing conscious states from unconscious ones empirically.

The “naturalistic turn” that has swept so many areas of philosophy over the past three decades has also had an impact in the last decade in legal philosophy. Methodological naturalists (M-naturalists) view philosophy as continuous with empirical inquiry in the sciences. Some M-naturalists want to replace conceptual and justificatory theories with empirical and descriptive theories; they take their inspiration from more-or-less Quinean arguments against conceptual analysis and foundationalist programs. Other M-naturalists retain the normative and regulative ambitions of (...) traditional philosophy, but emphasize that it is an empirical question what normative advice is actually useable and effective for creatures like us. Some M-naturalists are also.. (shrink)

The leading arguments against the existence of a priori knowledge are addressed. The opposing arguments fall into three broad categories: conceptual arguments, which offer an analysis of the concept of a priori knowledge and allege that no cases of knowledge satisfy the conditions in the analysis; radical empiricist arguments, which offer radical empiricist accounts of knowledge of propositions alleged to be knowable only a priori; and incompatibility arguments, which maintain that a priori knowledge (...) is incompatible with epistemic naturalism. This chapter contends that the negative arguments fail: the conceptual arguments impose implausible conditions on a priori knowledge; the radical empiricist accounts do not establish that the propositions in question are not also known a priori; and the incompatibility arguments fail to show that a priori knowledge is incompatible with either of the two leading forms of epistemic naturalism: philosophical and scientific.

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

The past decade has seen a burgeoning of scholarly interest in conscientious objection in healthcare. While the literature to date has focused primarily on individual healthcare practitioners who object to participation in morally controversial procedures, in this article we consider a different albeit related issue, namely, whether publicly funded healthcare institutions should be required to provide morally controversial services such as abortions, emergency contraception, voluntary sterilizations, and voluntary euthanasia. Substantive debates about institutional responsibility have remained largely at the level of (...) first-order ethical debate over medical practices which institutions have refused to offer; in this article, we argue that more fundamental questions about the metaphysics of institutions provide a neglected avenue for understanding the basis of institutional conscientious objection. To do so, we articulate a metaphysical model of institutional conscience, and consider three well-known arguments for undermining institutional conscientious objection in light of this model. We show how our metaphysical analysis of institutions creates difficulties for justifying sanctions on institutions that conscientiously object. Thus, we argue, questions about the metaphysics of institutions are deserving of serious attention from both critics and defenders of institutional conscientious objection. (shrink)

I argue that the three strongest arguments against metaphysical libertarianism—the randomness objection, the constitutive luck objection, and the physicalist objection—are actually unsuccessful and therefore that metaphysical libertarianism is more plausible than the common philosophical wisdom allows. My more positive thesis, what I will refer to as “Agent Exceptionalism,” is that, when making decisions and performing actions, human beings can indeed satisfy the four conditions of metaphysical libertarianism: the control condition, the rationality condition, the ultimacy condition, and the (...) physicalism condition.

Alvin Plantinga’s evolutionary argument against naturalism argues that the probability of our possessing reliable cognitive faculties, given the truth of evolution and naturalism, is low, and that this provides a defeater for naturalism, if the naturalist in question holds to the general truths of evolutionary biology. Stephen Law has recently objected to Plantinga’s evolutionary argument against naturalism by suggesting that there exist conceptual constraints governing the content a belief can have given its relationships to (...) other things, including behaviour . I show that Law’s objection fails, since it offers an auxiliary hypothesis to naturalism which is itself improbable. I consider multiple variants of the CC thesis, demonstrating that each is improbable, and that any weaker version with greater prior probability is compromised by a failure to render the relevant datum – the reliability of our cognitive faculties – probable. Thus, Law’s objection to Plantinga’s argument fails. (shrink)

John Haught offers a “critical intelligence” argument against naturalism. In this article, I outline Haught’s version of theistic evolution. Then I discuss the case he makes against naturalism with his critical intelligence argument. He uses two versions of the argument to make his case: a trustworthiness of critical intelligence argument and an ineffectiveness of naturalistic theories of the mind argument. I evaluate both versions of his critical intelligence argument against naturalism and find that they (...) contain false premises. They thus come up short in making a strong case against naturalism.

It is widely accepted that the ethical supervenes on the natural, where this is roughly the claim that it is impossible for two circumstances to be identical in all natural respects, but different in their ethical respects. This chapter refines and defends the traditional thought that this fact poses a significant challenge to ethical non-naturalism, a view on which ethical properties are fundamentally different in kind from natural properties. The challenge can be encapsulated in three core claims which (...) the chapter defends: that a defensible non-naturalism is committed to the supervenience of the ethical, that this commits the non-naturalist to a brute necessary connection between properties of distinct kinds, and that commitment to such brute connections counts against the non-naturalist’s view. Each of these claims has recently been challenged. Against Nicholas Sturgeon’s recent doubts about the dialectical force of supervenience, this chapter defends a supervenience thesis as deserving to be common ground among ethical realists. It is then argued that attempts to explain supervenience on behalf of the non-naturalist either fail as explanations, generate near-identical explanatory burdens elsewhere, or appeal to commitments that are inconsistent with core motivations for non-naturalism. The chapter concludes that, suitably refined, the traditional argument against non-naturalism from supervenience is alive and well. (shrink)

Evolutionary debunking arguments, whether defended by Street (2006), Joyce (2006), or others against moral realism, or by Plantinga (1993, 2011) and others against atheism, seek to determine the implications of the still-dominant worldview of naturalism. Examining them is thus a critical component of any defense of a theistic philosophy of nature. Recently, several authors have explored the connection between evolutionary debunking arguments against moral realism (hence: EDAs) and Plantinga’s evolutionary argument against naturalistic atheism (...) (hence: EAAN). Typically, responses in this vein have been critical of EDAs, arguing that they are in some way self-undermining. Different critics have argued that, in the course of defending the EAAN, the theist loses her best response to the probabilistic argument from evil for atheism. Here, I provide the first systematic comparison of all three arguments—EDAs, the EAAN, and the problem of evil—and suggest that the first charge succeeds while the second fails. (shrink)

Only in rational creatures is there found a likeness of God which counts as an image . . . . As far as a likeness of the divine nature is concerned, rational creatures seem somehow to attain a representation of [that] type in virtue of imitating God not only in this, that he is and lives, but especially in this, that he understands (ST Ia Q.93 a.6).

Alvin Plantinga has famously argued that the naturalist who accepts evolutionary theory has a defeater for all of her beliefs, including her belief in naturalism and evolution. Hence, he says, naturalism, when conjoined with evolution, is self defeating and cannot be rationally accepted. This is known as the evolutionary argument against naturalism (EAAN). However, Tyler Wunder (Religious Studies 51:391– 399, 2015) has recently shown that if the EAAN is framed in terms of objective probability and theism (...) is assumed to be non-contingent, then either theism is necessarily false or the EAAN is unsound. Neither option is attractive to the proponent of the EAAN. Perry Hendricks (Religious Studies 1–5, 2018) has responded to Wunder’s criticism, showing that the EAAN can be salvaged and, indeed, strengthened, by framing it in terms not of naturalism (N), but of a proposition that is entailed by N that is also consistent with theism. We will show that once Hendricks’ solution to Wunder’s objection is accepted, a puzzle ensues: if the EAAN provides the naturalist with a defeater for all of her beliefs, then an extension of it appears to provide God with a defeater for all of his beliefs. After bringing out this puzzle, we suggest several ways in which the proponent of the EAAN might solve it, but also show some potential weaknesses in these purported solutions. Whether the solutions to the puzzle that we consider ultimately succeed is unclear to us. (Translation: the authors disagree. One author thinks that the solutions (or,at least, some of them) that we consider do solve the puzzle while the other author does not.) However, it is clear to us that this is an issue that proponents of the EAAN need to address. (shrink)

This chapter contains sections titled: * Notes.

Foundationalism is false; after all, foundational beliefs are arbitrary, they do not solve the epistemic regress problem, and they cannot exist withoutother (justified) beliefs. Or so some people say. In this essay, we assess some arguments based on such claims, arguments suggested in recent work by Peter Klein and Ernest Sosa.

Contemporary discussions in metaphysics, epistemology and philosophy of mind are dominated by the presupposition of naturalism. Arguing against this established convention, Jim Slagle offers a thorough defence of Alvin Plantinga's Evolutionary Argument against Naturalism (EAAN) and in doing so, reveals how it shows that evolution and naturalism are incompatible. Charting the development of Plantinga's argument, Slagle asserts that the probability of our cognitive faculties reliably producing true beliefs is low if ontological naturalism is true, (...) and therefore all other beliefs produced by these faculties, including naturalism itself, are self-defeating. He critiques other well-known epistemological approaches, including those of Descartes and Quine, and deftly counters the many objections against the EAAN to conclude that epistemological naturalism should be rejected on the grounds of self-defeat. By situating Plantinga's argument within a wider context and showing that science and evolution cannot entail naturalism, Slagle renders this most common metaphysical view irrational. As such, the book advocates an important reconsideration of contemporary thought at the intersection of philosophy, science and religion. (shrink)

In this essay, I argue that prescription drug laws violate patients' rights to self-medication. Patients have rights to self-medication for the same reasons they have rights to refuse medical treatment according to the doctrine of informed consent (DIC). Since we should accept the DIC, we ought to reject paternalistic prohibitions of prescription drugs and respect the right of self-medication. In section 1, I frame the puzzle of self-medication; why don't the same considerations that tell in favour of informed consent also (...) justify a right of self-medication? In section 2, I show that the prescription drug system was historically motivated by paternalism. In section 3, I outline the justifications for the DIC in more detail. I show that consequentialist, epistemic, and deontic considerations justify the DIC. In sections 4–6, I argue that these considerations also justify rights of self-medication. I then propose that rights of self-medication require non-prohibitive prescription policies in section 7. I consider two objections in sections 8 and 9: that patients ought not to make medically risky or deadly decisions, and that unrestricted access to prescription-grade pharmaceuticals would result in widespread misuse and abuse. Section 10 concludes. (shrink)

This dissertation is a critique of synthetic ethical naturalism (SEN). SEN is a view in metaethics that comprises three key theses: first, there are moral properties and facts that are independent of the beliefs and attitudes of moral appraisers (moral realism); second, moral properties and facts are identical to (or constituted only by) natural properties and facts (ethical naturalism); and third, sentences used to assert identity or constitution relations between moral and natural properties are expressions of synthetic, (...) a posteriori necessities. The last of these theses, which distinguishes SEN from other forms of ethical naturalism, is supported by a fourth: the semantic contents of the central moral predicates such as 'morally right' and 'morally good' are fixed in part by features external to the minds of speakers (moral semantic externalism). Chapter 1 introduces SEN and discusses the most common motivations for accepting it. The next three chapters discuss the influential "Moral Twin Earth" argument against moral semantic externalism. In Chapter 2, I defend this argument from the charge that the thought experiment upon which it depends is defective. In Chapters 3 and 4, I consider two attempts to amend SEN so as to render it immune to the Moral Twin Earth argument. I show that each of these proposed amendments amounts to an abandonment of SEN. Chapter Five explores Richard Boyd's proposal that moral goodness is a "homeostatic property cluster." If true, Boyd's hypothesis could be used to support several metaphysical, epistemological, and semantic claims made on behalf of SEN. I advance three arguments against this account of moral goodness. In the sixth chapter, I argue that moral facts are not needed in the best a posteriori explanations of our moral beliefs and moral sensibility. Because of this, those who accept a metaphysical naturalism ought to deny the existence of such facts or else accept skepticism about moral knowledge. In Chapter 7, I consider a counterargument on behalf of SEN to the effect that moral facts are needed in order to explain the predictive success of our best moral theories. I show that this argument fails. (shrink)

In modern hospitals in developed countries, deaths are determined usually after a prearranged schedule of resuscitative efforts. By default, death is diagnosed and determined after “full code” or after the failure of intensive resuscitation. In end-of-life contexts, however, various degrees of less-than-full resuscitation and sometimes no resuscitation are allowed after the consent and shared decision-making of the patient and/or surrogates. The determination of brain death is a unique exception in these contexts because such an end-of-life care plan is usually not (...) offered until after brain death is declared. This essay analyzes and critiques three arguments for denying the family and/or surrogate a chance to consent to or forego the diagnostic protocol of brain death and choose an alternative end-of-life plan. First, opponents of consent for the determination of brain death argue that presenting it as a selectable end-of-life plan undermines the integrity of death determination. The second argument is that it is inconsistent to allow foregoing the determination of brain death when the determination of circulatory death is non-negotiable. The third argument is that allowing the patient/surrogate to forego the determination of brain death would jeopardize the fair and appropriate utilization of intensive care resources and potentially reduce organ donor pools. After closer conceptual examinations of these three arguments, this essay concludes that these arguments are conceptually and morally problematic. It defends an alternative patient-centered end-of-life care plan based on consent and shared decision-making. (shrink)

Metaphysical naturalism can be taken, roughly, to be the view that there is no God, and nothing beyond nature. Alvin Plantinga has argued that naturalism, in this sense, is self‐defeating. More specifically, he argues that an evolutionary account of human origins gives the naturalist compelling reasons for doubting the reliability of human cognitive faculties, and thus compelling reasons for doubting the truth of any of his beliefs, including naturalism itself. This argument, which has come to be known (...) as the ‘evolutionary argument against naturalism’, has generated a great deal of controversy, and a substantial literature concerning it has grown up as a result. In this paper, I will introduce readers to this literature. I begin by explaining the argument itself, and making clear its intuitive force. I then survey the main objections to it, such as the Perspiration Objection, the ‘Can’t the Naturalist Just Add a Little Something?’ Objection, and the Tu Quoque Objection: in the course of this survey, I pay particular attention to the most interesting of these, a version of the Tu Quoque Objection according to which the problem of evil results in a form of epistemic self‐defeat for the theist that is exactly analogous to the self‐defeat with which the naturalist is allegedly faced in the evolutionary argument. I go on to suggest that, despite the wide range of objections in the literature, the challenge of the evolutionary argument against naturalism is still very much with us, and I conclude by describing some promising directions for future research.

Alvin Plantinga's evolutionary argument against naturalism states that evolution cannot produce warranted beliefs. In contrast, according to Plantinga, Christian theism provides properly functioning cognitive faculties in an appropriate cognitive environment, in accordance with a design plan aimed at producing true beliefs. But does theism fulfill criteria I–III? Judging from the Bible, God employs deceit in his relations with humanity, rendering our cognitive functions unreliable. Moreover, there is no reason to suppose that God's purpose would be to produce true (...) beliefs in humans. Finally, from the theistic/religious perspective, it is impossible to tell whether observations have natural or supernatural causes, which undermines an appropriate cognitive environment. Reliable identification of deceit or miracles could alleviate these problems, but the theistic community has failed to resolve this issue. Dismissal of parts of the Bible, or attempts to find alternative interpretations, would collapse into skepticism or deism. Thus, Plantinga's problem of epistemic warrant backfires on theism.

Judith Thomson, David Lewis, and Ted Sider have each formulated different arguments that apparently pose problems for our ordinary claims of diachronic sameness, i.e., claims in which we assert that familiar, concrete objects survive (or persist) through time by enduring as numerically the same entity despite minor changes in their intrinsic or relational properties. In this paper, I show that all three arguments fail in a rather obvious way--they beg the question--and so even though there may be (...) arguments that provide grounds to fuss about whether our ordinary claims of diachronic sameness are defective, Thomson, Lewis, and Sider's arguments are not among them.

Inspired by Plantinga’s Evolutionary Argument Against Naturalism (EAAN), we develop an argument—the “Scriptural Argument Against Dogmatic Protestantism” (SAADP)—that Protestants who accept the doctrine of sola scriptura cannot reasonably hold that Catholic and Eastern churches are in doctrinal error. If sola scriptura is true and Catholic and Eastern Churches have fallen into error, it is improbable that any Protestant can reliably form true beliefs about controversial points of Christian doctrine, including sola scriptura or suggestions that Catholic and Eastern (...) Christians are in error. We evaluate potential responses to SADDP, considering how SAADP should affect ecumenical doctrinal debates. (shrink)

Quantum theory offers mathematical descriptions of measurable phenomena with great facility and accuracy, but it provides absolutely no understanding of why any particular quantum outcome is observed. It is the province of genuine explanations to tell us how things actually work—that is, why such descriptions hold and why such predictions are true. Quantum theory is long on the what, both mathematically and observationally, but almost completely silent on the how and the why. What is even more interesting is that, in (...) some sense, this state of affairs seems to be a necessary consequence of the empirical adequacy of quantum descriptions. One of the most noteworthy achievements of quantum theory is the accurate prediction of phenomena that, on pain of experimental contradiction, have no physical explanation. It is the purpose of this essay to make clear why quantum mechanics and quantum field theory are complete physical descriptions that describe the metaphysical incompleteness of the physical world, then to press the negative implications of this fact for naturalistic metaphysics.

Alvin Plantinga's evolutionary argument against naturalism makes the case that the conjunction of evolutionary theory and naturalism cannot be rationally believed, as, if both evolutionary theory and naturalism were true, it would be highly unlikely that our cognitive faculties are reliable. I present Plantinga's evolutionary argument against naturalism and survey a theory of meaning espoused by Robert Brandom, known as semantic inferentialism. I argue that if one accepts semantic inferentialism, as it is developed by (...) Brandom, then Plantinga's motivation for the evolutionary argument against naturalism is undermined. (shrink)

Intending to have a constructive dialogue with the combination of evolutionary theory (E) and metaphysical naturalism (N), Alvin Plantinga’s evolutionary argument against naturalism (EAAN) takes the reliability of human cognition (in normal environments) as a purported explanandum and E&N as a purported explanans. Then, he considers whether E&N can offer a good explanans for this explanandum, and his answer is negative (an answer employed by him to produce a defeater for N). But I will argue that the (...) whole EAAN goes wrong by assuming that R is a qualified explanandum crying out for scientific explanations, since it cannot meet either of the two criteria for any scientifically qualified explanandum: Realizability Criterion and Informativeness Criterion. Hence, EAAN is simply setting a task that E&N, as a scientific theory, will not care at all. Therefore, EAAN cannot substantially shake E&N. (shrink)

In this article (1) I extract from Brentano’s works (three) formal arguments against “genealogical explanations” of ethical claims. Such explanation can also be designated as “naturalism” (not his appellation); (2) I counter these arguments, by showing how genealogical explanations of even apodictic moral claims are logically possible (albeit only if certain unlikely, stringent conditions are met); (3) I show how Nietzsche’s ethics meets these stringent conditions, but evolutionary ethics does not. My more general thesis is (...) that naturalism and intuitionism in ethics need not be mutually incompatible. (shrink)

The rotating discs argument against perdurantism has been mostly discussed by metaphysicians, though the argument of course appeals to ideas from classical mechanics, especially about rotation. In contrast, I assess the RDA from the perspective of the philosophy of physics. I argue for three main conclusions. The first conclusion is that the RDA can be formulated more strongly than is usually recognized: it is not necessary to ‘imagine away’ the dynamical effects of rotation. The second is that in (...) general relativity, the RDA fails because of frame-dragging. The third conclusion is that even setting aside general relativity, the strong formulation of the RDA can after all be defeated, namely, by the perdurantist taking objects in classical mechanics to have only temporally extended temporal parts, which immediately blocks the RDA. Admittedly, this version of perdurantism defines persistence in a weaker sense of ‘definition’ than pointilliste versions that aim to define persistence assuming only instantaneous temporal parts. But I argue that temporally extended temporal parts can do the jobs within the endurantism– perdurantism debate that the perdurantist wants temporal parts to do and are supported by both classical and quantum mechanics.
