This article presents a challenge that those philosophers who deny the causal interpretation of explanations provided by population genetics might have to address. Indeed, some philosophers, known as statisticalists, claim that the concept of natural selection is statistical in character and cannot be construed in causal terms. On the contrary, other philosophers, known as causalists, argue against the statistical view and support the causal interpretation of natural selection. The problem I am concerned with here arises for the statisticalists because the (...) debate on the nature of natural selection intersects the debate on whether mathematical explanations of empirical facts are genuine scientific explanations. I argue that if the explanations provided by population genetics are regarded by the statisticalists as non-causal explanations of that kind, then statisticalism risks being incompatible with a naturalist stance. The statisticalist faces a dilemma: either she maintains statisticalism but has to renounce naturalism; or she maintains naturalism but has to content herself with an account of the explanations provided by population genetics that she deems unsatisfactory. This challenge is relevant to the statisticalists because many of them see themselves as naturalists. (shrink)

David Chalmers’ two-dimensionalism is an ambitious philosophical program that aims to “ground” or “construct” Fregean meanings and restore “the golden triangle” of apriority, necessity, and meaning that Kripke seemingly broke. This paper aims to examine critically what Chalmers’ theory can in reality achieve. It is argued that the theory faces severe challenges. There are some gaps in the overall arguments, and the reasoning is in some places somewhat circular. Chalmers’ theory is effectively founded on certain strong philosophical assumptions. It is (...) concluded that it is unclear whether the theory can deliver all it promises. (shrink)

The word ‘naturalism’ has a bewildering array of uses in philosophy. Roughly speaking, it connotes pro-scientific attitudes and approaches. This article introduces the subject of naturalism by sketching a history of pro-scientific attitudes and approaches in philosophy, from their origins in the early modern period through to the present day. It then distinguishes a number of distinct families of naturalism: metaphysical, logico-linguistic, epistemological, and methodological. The resulting taxonomy encompasses a plurality of loosely related views rather than a number of variations (...) on a single clear and unified theme. (shrink)

Creationists have long argued that evolutionary science is committed to a dogmatic metaphysics of naturalism and materialism, which is based on faith or ideology rather than evidence. The standard response to this has been to insist that science is not committed to any such metaphysical doctrine, but only to a methodological version of naturalism, according to which science may only appeal to natural entities and processes. But this whole debate presupposes that there is a clear distinction between the natural and (...) the supernatural, and thus that naturalism is a meaningful doctrine. I argue that this assumption is false. The concepts of the natural and the supernatural are in fact hopelessly obscure, such that the claim that science is committed to methodological naturalism cannot be made good. This is no victory for anti-naturalists however; explicitly supernaturalist theories, such as Creationism, can be ruled out of scientific consideration as a priori incoherent, given that they presuppose for their intelligibility that there is a meaningful natural-supernatural distinction. This is not the case for standard scientific theories however, as they are not explicitly naturalistic theories; they do not postulate natural or physical entities or processes as such. (shrink)

O objectivo deste artigo consiste em introduzir a noção de conhecimento a priori e os problemas que a envolvem. Começa-se por caracterizar o conhecimento a priori e aquilo que o distingue do conhecimento a posteriori para de seguida avaliar-se as dificuldades que uma compreensão adequada da noção de independência da experiência enfrenta. A noção de a priori é distinguida da de necessidade, à qual, tradicionalmente, tem sido associada. Por fim, o problema do a priori é formulado e as principais teorias (...) que a ele respondem brevemente discutidas. (shrink)

How should one conceive of the method of mathematics, if one takes a naturalist stance? Mathematical knowledge is regarded as the paradigm of certain knowledge, since mathematics is based on the axiomatic method. Natural science is deeply mathematized, and science is crucial for any naturalist perspective. But mathematics seems to provide a counterexample both to methodological and ontological naturalism. To face this problem, some naturalists try to naturalize mathematics relying on Darwinism. But several difficulties arise when one tries to naturalize (...) in this way the traditional view of mathematics, according to which mathematical knowledge is certain and the method of mathematics is the axiomatic method. This paper suggests that, in order to naturalize mathematics through Darwinism, it is better to take the method of mathematics not to be the axiomatic method. (shrink)

Evidential holism begins with something like the claim that “it is only jointly as a theory that scientific statements imply their observable consequences.” This is the holistic claim that Elliott Sober tells us is an “unexceptional observation”. But variations on this “unexceptional” claim feature as a premise in a series of controversial arguments for radical conclusions, such as that there is no analytic or synthetic distinction that the meaning of a sentence cannot be understood without understanding the whole language of (...) which it is a part and that all knowledge is empirical knowledge. This paper is a survey of what evidential holism is, how plausible it is, and what consequences it has. Section 1 will distinguish a range of different holistic claims, Sections 2 and 3 explore how well motivated they are and how they relate to one another, and Section 4 returns to the arguments listed above and uses the distinctions from the previous sections to identify holism's role in each case.

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)

W.V. Quine is committed to the claim that all beliefs are rationally revisable; Jerrold Katz has argued that this commitment is unstable on grounds of self-application. The subsequent discussion of this issue has largely proceeded in terms of the logic of belief revision, but there is also an issue here for the treatment of Quine’s views in a doxastic modal system. In this paper I explore the treatment of Quinean epistemology in modal terms. I argue that a set of formal (...) revisability desiderata can be distilled from Quine’s epistemic writings, and that there are demonstrably coherent and non-trivial systems that meet these conditions.

Most contemporary philosophers of mind claim to be in search of a 'naturalistic' theory. However, when we look more closely, we find that there are a number of different and even conflicting ideas of what would count as a 'naturalization' of the mind. This article attempts to show what various naturalistic philosophies of mind have in common, and also how they differ from one another. Additionally, it explores the differences between naturalistic philosophies of mind and naturalisms found in ethics, epistemology, (...) and philosophy of science. Section 1 introduces a distinction between two types of project that have been styled 'naturalistic', which I call philosophical naturalism and empirical naturalism . Sections 2 to 6 canvass different strands of philosophical naturalism concerning the mind, followed by a much briefer discussion of attempts to provide empirical naturalizations of the mind in Section 7 . Section 8 concludes the essay with a consideration of the relations between philosophical and empirical naturalism in philosophy of mind, arguing that at least some types of philosophical naturalism are incompatible with empirical naturalism.

This paper is an examination of evidential holism, a prominent position in epistemology and the philosophy of science which claims that experiments only ever confirm or refute entire theories. The position is historically associated with W.V. Quine, and it is at once both popular and notorious, as well as being largely under-described. But even though there’s no univocal statement of what holism is or what it does, philosophers have nevertheless made substantial assumptions about its content and its truth. Moreover they (...) have drawn controversial and important conclusions from these assumptions. In this paper I distinguish three types of evidential holism and argue that the most oft-cited and controversial thesis is entirely unmotivated. The other two theses are much overlooked, but are well-motivated and free from controversial implications. (shrink)

Given the enchanted worldview of pentecost-alism, what possibility is there for a uniquely pentecostal intervention in the science-theology dialogue? By asserting the centrality of the miraculous and the fantastic, and being fundamentally committed to a universe open to surprise, does not pentecostalism forfeit admission to the conversation? I argue for a distinctly pentecostal contribution to the dialogue that is critical of regnant naturalistic paradigms but also of a naive supernaturalism. I argue that implicit in the pentecostal social imaginary is a (...) distinct conception of nature that is amenable to science but in conflict with naturalism. (shrink)

Moderate rationalists maintain that our rational intuitions provide us with prima facie justification for believing various necessary propositions. Such a claim is often criticized on the grounds that our having reliable rational intuitions about domains in which the truths are necessary is inexplicable in some epistemically objectionable sense. In this paper, I defend moderate rationalism against such criticism. I argue that if the reliability of our rational intuitions is taken to be contingent, then there is no reason to think that (...) our reliability is inexplicable. I also suggest that our reliability is, in fact, necessary, and that such necessary reliability neither admits of, nor requires, any explanation of the envisaged sort. (shrink)

Linguists take the intuitive judgments of speakers to be good evidence for a grammar. Why? The Chomskian answer is that they are derived by a rational process from a representation of linguistic rules in the language faculty. The paper takes a different view. It argues for a naturalistic and non-Cartesian view of intuitions in general. They are empirical central-processor responses to phenomena differing from other such responses only in being immediate and fairly unreflective. Applying this to linguistic intuitions yields an (...) explanation of their evidential role without any appeal to the representation of rules. Introduction The evidence for linguistic theories A tension in the linguists' view of intuitions Intuitions in general Linguistic intuitions Comparison of the modest explanation with the standard Cartesian explanation A nonstandard Cartesian explanation of the role of intuitions?

W. V. Quine famously claimed that no statement is immune to revision. This thesis has had a profound impact on twentieth century philosophy, and it still occupies centre stage in many contemporary debates. However, despite its importance it is not clear how it should be interpreted. I show that the thesis is in fact ambiguous between three substantially different theses. I illustrate the importance of clarifying it by assessing its use in the debate against the existence of a priori knowledge. (...) I show how the three different readings of the thesis can be used to generate three substantially different and philosophically significant arguments against the a priori. I further challenge each one of these arguments against the a priori. (shrink)

ABSTRACT: This paper develops an account of what it is for a proposition to be self- evident to someone, based on the idea that certain propositions are such that to fully understand them is to believe them. It argues that when a proposition p is self-evident to one, one has non-inferential a priori justification for believing that p and, a welcome feature, a justification that does not involve exercising any special sort of intuitive faculty; if, in addition, it is true (...) that p and there exists no reason to believe that the proposition that p is incoherent, then one knows a priori that p. The paper argues that certain deeply contingent truths, e.g., the truth that I would now express by saying “I exist”, can be self-evident to, and thus known a priori by, the person they are about at the time they are about; but, since they cannot be known a priori, or even expressed, by anyone else or at any other time, they should not count as a priori truths.

Paul Benacerraf’s argument that mathematical realism is apparently incompatible with mathematical knowledge has been widely thought to also show that a priori knowledge in general is problematic. Although many philosophers have rejected Benacerraf’s argument because it assumes a causal theory of knowledge, some maintain that Benacerraf nevertheless put his finger on a genuine problem, even though he didn’t state the problem in its most challenging form. After diagnosing what went wrong with Benacerraf’s argument, I argue that a new, more challenging, (...) version of Benacerraf’s problem can be constructed. The new version—what I call the Defeater Version—of Benacerraf’s problem makes use of a no-defeater condition on knowledge and justification. I conclude by arguing that the best way to avoid the problem is to construct a theory of how a priori judgments reliably track the facts. I also suggest four different kinds of theories worth pursuing. (shrink)

I argue that there are analytic claims that, if true, can be known a priori, but which also can turn out to be false: they are expressive of merely default instructions from the language faculty to the conceptual system, which may be overridden by pragmatic or scientific considerations, in which case, of course, they would not be known at all, a priori or otherwise. More surprisingly, I also argue that they might not be, strictly speaking, conceptual: concepts may be importantly (...) different from the meaning instructions for the words we use to express them. I will press all this in the context of a general Quinean “naturalism,” where the epistemology that interests me is “a chapter of natural science,” but where the science won't be Quine's behaviorism, but a Chomskyan theory of the “I-semantics” of “I-language.” But, relying on a distinction I draw between an explanatory and a working epistemology, I will be pressing it largely as an explanatory claim, not one that will have serious consequences for on-going philosophical practice, neither with regard to the world, nor, more surprisingly, even with regard to armchair “conceptual analysis.” As Putnam observed, there may be analytic truths, but they don't cut much philosophical ice.
