Scientific realism is the position that the aim of science is to advance on truth and increase knowledge about observable and unobservable aspects of the mind-independent world which we inhabit. This book articulates and defends that position. In presenting a clear formulation and addressing the major arguments for scientific realism Sankey appeals to philosophers beyond the community of, typically Anglo-American, analytic philosophers of science to appreciate and understand the doctrine. The book emphasizes the epistemological aspects of scientific realism and contains (...) an original solution to the problem of induction that rests on an appeal to the principle of uniformity of nature.

Some think that issues to do with scientific method are last century's stale debate; Popper was an advocate of methodology, but Kuhn, Feyerabend, and others are alleged to have brought the debate about its status to an end. The papers in this volume show that issues in methodology are still very much alive. Some of the papers reinvestigate issues in the debate over methodology, while others set out new ways in which the debate has developed in the last decade. The (...) book will be of interest to philosophers and scientists alike in the reassessment it provides of earlier debates about method and current directions of research. (shrink)

There are two chief tasks which confront the philosophy of scientific method. The first task is to specify the methodology which serves as the objective ground for scientific theory appraisal and acceptance. The second task is to explain how application of this methodology leads to advance toward the aim(s) of science. In other words, the goal of the theory of method is to provide an integrated explanation of both rational scientific theory choice and scientific progress.

The nature of the distinction between rational andnon-rational accounts of the development of science isanalyzed. These two kinds of accounts differ mostlyin the status which they give to methodologicalprinciples. It is shown that there are severaldimensions with respect to which the status of suchprinciples can resemble more or less the kind ofstatus that a paradigmatic rational account would givethem. It is concluded that, under the most plausibledefinitions of a rational account, the extent to whicha philosophical account of scientific change isrational (...) is a matter of degree, and that there is nosuch clear distinction between the two kinds ofaccounts which some supporters of rational and ofnon-rational accounts have assumed to exist.

In this paper, I explore the relationship between epistemic rationality and instrumental rationality, and I attempt to delineate their respective roles in typical instances of theoretical reasoning. My primary concern is with the instrumentalist conception of epistemic rationality: the view that epistemic rationality is simply a species of instrumental rationality, viz. instrumental rationality in the service of one's cognitive or epistemic goals. After sketching the relevance of the instrumentalist conception to debates over naturalism and 'the ethics of belief', I argue (...) that, despite enjoying considerable popularity among both epistemologists and philosophers of science, it is ultimately indefensible. Having thus argued for the distinctness of epistemic and instrumental rationality, I attempt to clarify the role played by each in typical instances of theoretical reasoning. I suggest that being theoretically rational--that is, being proficient with respect to theoretical reasoning--is best construed as a hybrid virtue, inasmuch as it involves manifesting sensitivity to two very different kinds of reasons.

Philosophers of science are divided over the interpretations of scientific normativity. Larry Laudan defends a sort of goal-directed rules for scientific methodology. In contrast, Gerard Doppelt thinks methodological rules are a mixed batch of rules in that some are goal-oriented hypothetical rules and others are goal-independent categorical rules. David Resnik thinks that the debate between them is at a standstill now. He further thinks there are certain rules, such as the rule of consistency which is goal independent. However, he proposes (...) a holistic understanding of the scientific methodology. Taking a thread from Resnik, the present paper also advocates a holistic understanding of the scientific methodology. Given that many scientific practices deal with systems, the focus will be given to the systems by assuming each as a constellation of methodological norms. By taking each system as a set of mutually supportive methodological rules whose instrumental values underwrite the coherence relation among them, the paper aims to provide what could be a viable holistic epistemological account that can explain scientific normativity at work in a scientific system. The paper will lay down specific holistic criteria for understanding the scientific methodology. They will be used to show how a holistic account could satisfactorily account for the success of the Compact Muon Solenoid (CMS) experiment in discovering the Higgs boson and how the holistic account can account for the instrumental error behind the apparent faster-than-light neutrino anomaly of the Oscillation Project with Emulsion-t Racking Apparatus (OPERA) experiments respectively.

Scientific disputes about how often different processes or patterns occur are relative frequency controversies. These controversies occur across the sciences. In some areas—especially biology—they are even the dominant mode of dispute. Yet they depart from the standard picture of what a scientific controversy is like. In fact, standard philosophical accounts of scientific controversies suggest that relative frequency controversies are irrational or lacking in epistemic value. This is because standard philosophical accounts of scientific controversies often assume that in order to be (...) rational, a scientific controversy must reach a resolution and be about a scientifically interesting question. Relative frequency controversies rarely reach a resolution, however, and some scientists and philosophers are skeptical that these controversies center on scientifically interesting questions. In this paper, I provide a novel account of the epistemic contribution that relative frequency controversies make to science. I show that these controversies are rational in the sense of furthering the epistemic aims of the scientific communities in which they occur. They do this despite rarely reaching a resolution, and independent of whether the controversies are about scientifically interesting questions. This means that assumptions and about what is required for a controversy to be rational are wrong. Controversies do not need to reach a resolution in order to be rational. And they do not need to be about anything scientifically interesting in order to make valuable epistemic contributions to science. (shrink)

I argue that if simplicity is a theoretical virtue and some theoretical virtues are the constituents of the aims of theorizing in physics—i.e., theory choice and theory development in physics—and scientific rationality is instrumental rationality, then simplicity cannot be a mere means to achieve the aims. I do this by showing that considering simplicity as a mere means brings about counterintuitive ramifications concerning scientific rationality. These counterintuitive ramifications can be avoided if we consider simplicity a constituent of the aims of (...) theorizing in physics. (shrink)

Critique of instrumental accounts of epistemic rationality.

Epistemic instrumentalism views epistemic norms and epistemic normativity as essentially involving the instrumental relation between means and ends. It construes notions like epistemic normativity, norms, and rationality, as forms of instrumental or means-end normativity, norms, and rationality. I do two main things in this paper. In part 1, I argue that there is an under-appreciated distinction between two independent types of epistemic instrumentalism. These are instrumentalism about epistemic norms and instrumentalism about epistemic normativity. In part 2, I argue that this (...) under-appreciated distinction matters for the debate surrounding the plausibility of EI. Specifically, whether we interpret EI as norm-EI or as source-EI matters for the widely discussed universality or categoricity objection to EI, and for two important motivations for adopting EI, namely naturalism and the practical utility of epistemic norms. I will then conclude by drawing some lessons for epistemic instrumentalism going forward. (shrink)

In this essay, I aim to motivate and defend a pluralistic view of epistemic rationality. At the core of the view is the notion that epistemic rationality is essentially a species of practical rationality put in the service of various epistemic goals. I begin by sketching some closely related views that have appeared in the literature. I then present my preferred version of the view and sketch some of its benefits. Thomas Kelly has raised challenging objections to a part of (...) the view, which I then present and address. I then raise some distinct worries that might linger and sketch some possible ways one might address them. (shrink)

In this article I argue that a methodological challenge to an integrated history and philosophy of science approach put forth by Ronald Giere almost forty years ago can be met by what I call the Kuhnian mode of History and Philosophy of Science (HPS). Although in the Kuhnian mode of HPS norms about science are motivated by historical facts about scientific practice, the justifiers of the constructed norms are not historical facts. The Kuhnian mode of HPS therefore evades the naturalistic (...) fallacy which Giere’s challenge is a version of. Against the backdrop of a discussion of Laudan’s normative naturalism I argue that the Kuhnian mode of HPS is a superior form of naturalism: it establishes contact to the practice of science without making itself dependent on its contingencies.

The critical focus of this paper is on a claim made explicitly by Gilbert Harman and accepted implicitly by numerous others, the claim that naturalism supports concurrent defense of scientific objectivism and moral relativism. I challenge the assumptions of Harman's ‘argument from naturalism' used to support this combination of positions, utilizing. Hilary Putnam’s ‘companions in guilt’ argument in order to counter it. The paper concludes that while domain-specific anti-realism is often warranted, Harman’s own views about the objectivity of facts and (...) the subjectivity of values are better seen as stemming from scientistic ideals of knowledge than from dictates of naturalism. Scientists qua scientists make value judgments, and setting aside scientistic assumptions and unrealizable conceptions of scientific objectivity should lead us to more symmetrical metaphilosophical conception of epistemic and ethical normativity than that which underlies Harman's account.

Doppelt (1986,1990), Siegel (1990), and Rosenberg (1996) argue that the pivotal feature of Laudan's normative naturalism, namely his axiology, lacks a naturalistic foundation. In this paper I show that this objection turns on a misunderstanding of Laudan's use of the term 'naturalism'. Specifically, I argue that there are two important senses of naturalism running through Laudan's work. Once these two strands are made explicit, the objection raised by Doppelt and others simply disappears.

We are bombarded with epistemic norms. Respect your evidence. Don’t believe in contradictions. Don’t arbitrarily change beliefs. But how do such norms get their normative force? Why should we respect our evidence, for example? In this paper I offer a familiar type of answer, epistemic instrumentalism. Epistemic instrumentalism holds that epistemic norms get their normative force by being useful. You should respect your evidence because it will help you achieve some valuable ends. This answer, while familiar, is not very popular. (...) There is a widely accepted objection to epistemic instrumentalism, the too few reasons objection. The objection looms so large that standard developments of instrumentalism have become bloated with philosophical machinery to respond to it. This does a disservice to epistemic instrumentalism. Rather than focusing completely on the objection, I focus on describing a simple model for how conforming to the epistemic norms is broadly useful. Once I describe the simple model, the too few reasons objection becomes much easier to answer. This strategy results in a well-motivated philosophical theory based on uncontroversial facts that has many advantages over rival theories. (shrink)

Are epistemic reasons merely a species of instrumental practical reasons, making epistemic rationality a specialized form of instrumental practical rationality? Or are epistemic reasons importantly different in kind? Despite the attractions of the former view, Kelly (2003) argues quite compellingly that epistemic rationality cannot be merely a matter of taking effective means to one’s epistemic ends. I argue here that Kelly’s objections can be sidestepped if we understand epistemic reasons as instrumental reasons that arise in light of the aims held (...) by social collectives of which we are members, rather than being fixed by our own individual goals. This social version of epistemic instrumentalism would not be subject to counterexamples that point to the failure of individual people to possess desires or goals that would account for all of the epistemic reasons we find it natural to attribute to them. I conclude by comparing the proposed view to the alternative version of instrumentalism defended by Kornblith (1993). I argue that the social view I sketch here has one noteworthy advantage. It better accounts for the intuitive distinctness of our practical and epistemic reasons for belief in cases where flouting epistemic norms would better help us to achieve our own individual goals.

The aim of this thesis dissertation is to propose a novel position in the debate on scientific realism, modal empiricism, and to show its fruitfulness when it comes to interpreting the cognitive content of scientific theories. Modal empiricism is an empiricist position, according to which the aim of science is to produce empirically adequate theories rather than true theories. However, it suggests adopting a broader comprehension of experience than traditional versions of empiricism, through a commitment to natural modalities. Following modal (...) empiricism, there are possibilities in nature, and constraints on what is possible, and a theory is empirically adequate if it correctly delimits the range of possible experiences. The position rests on a situated and pragmatic conception of natural modalities and of empirical confrontation. We claim that it can do justice to the empirical success of science, while not falling prey to the problem of theory change that undermines scientific realism. We explain how constraints of necessity on phenomena can be known by induction, and how this modal epistemology fits with scientific practice. Finally, we claim that a commitment to natural modalities allows for a rich interpretation of the cognitive content of theories. Modal empiricism could renew some metaphysical debates within a pragmatist framework, by tying them to experience and not being constrained by realist prejudices. -/- L'objet de cette thèse est de proposer une position originale dans le débat sur le réalisme scientifique, l'empirisme modal, et d'en démontrer la fructuosité quand il s'agit de tirer des enseignements du contenu cognitif des théories scientifiques. L'empirisme modal est une position empiriste, suivant laquelle le but de la science n'est pas de produire des théories vraies, mais des théories empiriquement adéquate. Cependant, il propose d'adopter un cadre plus large que les versions traditionnelles d'empirisme pour penser l'expérience, en incorporant un engagement envers les modalités naturelles, ou l'idée qu'il y a du possible dans la nature, et des contraintes sur les possibles. Nos théories sont empiriquement adéquates si elles délimitent correctement l'étendue des expériences possibles. Cette position s'appuie sur une conception située et pragmatique des modalités naturelles et de la confrontation empirique. Nous prétendons qu'elle est à même de rendre justice au succès empirique des sciences, sans pour autant faire face au problème du changement théorique qui mine le réalisme scientifique. Nous expliquons comment les contraintes de nécessité sur les phénomènes peuvent être connues à l'issue d'une induction, et en quoi cette façon de voir s'accorde avec la pratique scientifique. Enfin, nous affirmons qu'un engagement envers les modalités naturelles offre une richesse interprétative à même de renouveler, dans un cadre pragmatiste, plus ouvert que le réalisme, certaines questions métaphysiques tout en les ramenant à l'expérience .

Epistemic instrumentalists seek to understand the normativity of epistemic norms on the model practical instrumental norms governing the relation between aims and means. Non-instrumentalists often object that this commits instrumentalists to implausible epistemic assessments. I argue that this objection presupposes an implausibly strong interpretation of epistemic norms. Once we realize that epistemic norms should be understood in terms of permissibility rather than obligation, and that evidence only occasionally provide normative reasons for belief, an instrumentalist account becomes available that delivers the (...) correct epistemic verdicts. On this account, epistemic permissibility can be understood on the model of the wide-scope instrumental norm for instrumental rationality, while normative evidential reasons for belief can be understood in terms of instrumental transmission.

Naturalists seek continuity between epistemology and science. Critics argue this illegitimately expands science into epistemology and commits the fallacy of scientism. Must naturalists commit this fallacy? I defend a conception of naturalized epistemology which upholds the non-identity of epistemic ends, norms, and concepts with scientific evidential ends, norms, and concepts. I argue it enables naturalists to avoid three leading scientistic fallacies: dogmatism, one dimensionalism, and granting science an epistemic monopoly.

In a time when we as a society are in the process of deciding what our basic rights to health care are, it is critically important for us to have a full and complete understanding of what constitutes health. We argue for an analysis of health according to which certain states are healthy not in themselves but because they allow an individual to reach actual goals. Recognizing that the goals of an individual considered from the point of view of biology (...) and the goals of the same individual considered as an agent in the world might be different, we introduce a distinction between the health of an individual qua organism and the health of an individual qua person. We then argue that this distinction characterizes the evaluations made by patients and healthcare providers better than the widely discussed distinction between disease and illness. (shrink)

In this paper, I argue against the view that epistemic reasons are normative reasons for belief. I begin by responding to some of the most widespread arguments in favor of the normativity of epistemic reasons before advancing two arguments against this thesis. The first is supported by an analysis of what it means to “have” some evidence for p. The second is supported by the claim that beliefs, if they are to be considered as states, cannot have epistemic reasons as (...) normative reasons. (shrink)

When Bloor's Knowledge and Social Imagery was first published in 1976, it was not the first time that a “strong programme” in the sociology of knowledge was treated to a hostile reception by philosophers. But never before has such a dialectically unproductive encounter with philosophers led to such a methodologically fruitful response, for, when an array of positivist, historicist, Popperian, and realist philosophers argued against Bloor and his Edinburgh colleagues that normative accounts of scientific rationality could not be refuted by (...) empirical accounts of what scientists do, an entire line of research was launched that sought to explain science without having to make reference to the philosophers' cherished norms. This is the field now known as Science and Technology Studies. Although STS is normally taken to be intellectually centered in sociology, its main practitioners are just as likely to have been drawn from philosophy and the natural sciences as from the social sciences proper. The unmistakable mark of Bloor's influence is that, unlike the sociology of science most recognizable to sociologists, the STS practitioner is committed to studying science in the same spirit of analytic detachment and epistemic neutrality as she would any other aspect of society. In practice, this has amounted to a preference for methods that incorporate “ethnographic distance”, although in recent years theoretical debate has increasingly focused on the appropriate attitude that STS practitioners should adopt toward science, given their findings to date. I will return to this debate at the end of this essay. (shrink)

In two recent papers, I criticized Ronald N. Giere's and Larry Laudan's arguments for 'naturalizing' the philosophy of science (Siegel 1989, 1990). Both Giere and Laudan replied to my criticisms (Giere 1989, Laudan 1990b). The key issue arising in both interchanges is these naturalists' embrace of instrumental conceptions of rationality, and their concomitant rejection of non-instrumental conceptions of that key normative notion. In this reply I argue that their accounts of science's rationality as exclusively instrumental fail, and consequently that their (...) cases for 'normatively naturalizing' the philosophy of science fail as well.

For as long as realists and instrumentalists have disagreed, partisans of both sides have pointed in argument to the actions and sayings of scientists. Realists in particular have often drawn comfort from the literal understanding given even to very theoretical propositions by many of those who are paid to deploy them. The scientists' realism, according to the realist, is not an idle commitment: a literal understanding of past and present theories and concepts underwrites their employment in the construction of new (...) theories. The theme of this book is philosophy and technology, and here's the connection: new theories point out—and explain—new phenomena. So realism, claim the realists, is at the heart of science's achievement of what Bacon, that early philosopher of technology, identified as science's aim: new knowledge offering new powers. (shrink)

“Naturalized epistemology” is a recent attempt to transform the theory of knowledge into a branch of natural science. Traditional epistemologists object to this proposal on the grounds that it eliminates the distinctively philosophical content of epistemology. In this thesis, I argue that traditional philosophers are justified in their reluctance to accept naturalism, but that their ongoing inability to refute it points to deeper problems inherent in traditional epistemology. I establish my thesis first by critiquing three versions of naturalism, showing that (...) each version either fails to implement its objectives consistently or starts from dubious objectives. “Optimistic naturalism” attempts to use naturalistic methods to give positive answers to traditional epistemological questions (such as by affirming that our beliefs can be justified). This fails because the form of traditional questions requires the concept “belief,” a concept that I argue naturalistic methodology cannot countenance (because of the severe constraints of naturalistic semantic theory). “Pessimistic naturalism,” the version advocated by Quine, is more consistent with naturalistic methodology, but fails because hidden behind its conclusions are assumptions (such as the underdetermination thesis) that cannot themselves be naturalized in the full context of scientific evidence. A final attempt to naturalize epistemology, deflationary naturalism, dispenses with traditional questions entirely, urging that the terms “knowledge” and “justification” be taken as mere pragmatic devices whose use can, nevertheless, be studied scientifically. Curiously, this view fails to take account of important facts about the actual use of those terms, as studied by psychologists. In the end, despite problems with each of these versions, traditional philosophers can learn something from their encounter with naturalism. In the course of showing how various naturalistic doctrines cannot themselves be naturalized, I identify the flaws in traditional epistemology (such as its reliance on a priorism, and its resulting inability to articulate a workable empirical foundationalist theory of justification) that make naturalism harder to challenge. These flaws must be corrected if philosophers are to preserve the autonomy of their discipline. (shrink)

Philosophers use historical case studies to support wide-ranging claims about science. This practice is often criticized as problematic. In this paper we suggest that the function of case studies can be understood and justified by analogy to a well-established practice in biology: the investigation of model organisms. We argue that inferences based on case studies are no more problematic than inferences from model organisms to larger classes of organisms in biology. We demonstrate our view in detail by reference to a (...) case study with a long history: Semmelweis’s discovery of the cause of childbed fever. (shrink)

In this paper I argue that the Strong Programme’s aim to provide robust explanations of belief acquisition is limited by its commitment to the symmetry principle. For Bloor and Barnes, the symmetry principle is intended to drive home the fact that epistemic norms are socially constituted. My argument here is that even if our epistemic standards are fully naturalized—even relativized—they nevertheless can play a pivotal role in why individuals adopt the beliefs that they do. Indeed, sometimes the fact that a (...) belief is locally endorsed as rational is the only reason why an individual holds it. In this way, norms of rationality have a powerful and unique role in belief formation. But if this is true then the symmetry principle’s emphasis on ‘sameness of type’ is misguided. It has the undesirable effect of not just naturalizing our cognitive commitments, but trivializing them. Indeed, if the notion of ‘similarity’ is to have any content, then we are not going to classify as ‘the same’ beliefs that are formed in accordance with deeply entrenched epistemic norms as ones formed without reflection on these norms, or ones formed in spite of these norms. My suggestion here is that we give up the symmetry principle in favor of a more sophisticated principle, one that allows for a taxonomy of causes rich enough to allow us to delineate the unique impact epistemic norms have on those individuals who subscribe to them.Keywords: Strong Programme; Naturalism; Epistemology; David Bloor; Barry Barnes.

In experimental scientific research, such as that conducted in High-Energy Physics (HEP), there are a number of problems which are unique to the experimental endeavor in contrast to theoretical research. The preparation of a sample of data to be analyzed requires a number of complicated and interrelated procedures to insure the purity or quality of the data. Thus, for example, in an experimental study of meson-baryon scattering, the separation of events of one type of scattering from others of similar configuration (...) (see the discussion of different configurations in section II) requires intricate and sophisticated procedures along with the application of a number of criteria and standards of analysis. In the case of theoretical research, there are a number of philosophical discussions which formulate certain criteria or norms that theorists usually invoke in their evaluation of theories as well as in the actual choice of one theory over another.

In this paper I look at three challenges to the very possibility of an ethics of belief and then show how they can be met. The first challenge, from Thomas Kelly, says that epistemic rationality is not a form of instrumental rationality. If this claim is true, then it will be difficult to develop an ethics of belief that does not run afoul of naturalism. The second challenge is the Non-Voluntarism Argument, which holds that because we cannot believe at will (...) and because ought implies can, there can be no ethics of belief. The third challenge comes from Richard Feldman, who claims that there is no such thing as ought all-things-considered. He says, for example, that moral oughts can be weighed against other moral oughts and that epistemic oughts can be compared to each other, but that there is no way to weigh moral oughts against epistemic oughts. If this is true, then norms about what one ought to believe are not nearly as important as one might have hoped or as philosophers have traditionally thought. In answering these three challenges, I try to show how and why the project of developing epistemic norms might be a promising avenue of research, despite claims to the contrary. (shrink)

Advocates of the strong programme in the sociology of knowledge contend that its four defining tenets entail the elimination and replacement tout court of epistemology by strong sociology of knowledge. I advance a naturalistic conception of both substantive and meta-level epistemological inquiry which fully complies with these four tenets and thereby shows that the strong programme neither entails nor even augurs the demise of epistemology.

In previous work, I defended Larry Laudan against the criticism that the axiological component of his normative naturalism lacks a naturalistic justification. I argued that this criticism depends on an equivocation over the term 'naturalism' and that it begs the question against what we are entitled to include in our concept of nature. In this paper, I generalize that argument and explore its implications for Laudan and other proponents of epistemic naturalism. Here, I argue that a commitment to naturalism in (...) the methods and aims of science inevitably entails a kind of epistemic relativism. However, I argue that this should not be interpreted as a reductio of naturalism, since the admission of contextually based standards and aims of science does not result in quietism when it comes to important questions concerning scientific rationality.

Rather than attempting to combine the two meta-methodological programmes for justifying the epistemological study of science, which is the case of Laudan's normative naturalism, this paper aims at presenting a third alternative to the controversy between the traditional normativism and the reductionistic naturalism. The paper is a preliminary move in developing a theory of the autopoietic cognitive organization of science. The underlying assumption of this project calls that science is a self-constructing, self-specifying and homeostatic system. The scrutinizing of these three (...) predicates leads to the view that the epistemological propositions about science cognitive organization are neither normative, nor descriptive, but transcendental ones. The final discussion shows the connection between this project and the theory of group rationality. (shrink)

Este artículo discute varios modos de entender la racionalidad de la ciencia como racionalidad práctica. En primer lugar, rechaza los modelos instrumentalistas de la racionalidad científica, porque no pueden mostrar la independencia y la bondad de fines definidos para la ciencia, en relación con los cuales se establece la fuerza normativa de las razones. La errónea identificación de fines y valores es lo que provoca numerosas confusiones en este terreno. Se critica, en segundo lugar, un modelo de racionalidad práctica basado (...) en el dominio de saberes tácitos y habilidades. Cualquiera de los modelos propuestos ha de acomodarse a tres restricciones sobre lo que puede ser una "buena razón" dentro de la ciencia y que conforman la identidad práctica y el rostro normativo de la ciencia: publicidad, fiabilidad y autoridad reflexiva. This paper discusses some ways of understanding scientific rationality as practical rationality. Firstly, instrumental models of the rationality of science are rejected. The instrumentalist can hardly establish the independence and goodness of certain ends. In the case of science, determinate ends with respect to which the normative force of our reasons is established do not seem to exist. A false identification of ends with values is what causes many of the confusions. Secondly, a model of practical rationality based in the mastery of tacit knowledge and skills is criticized. Any model of scientific rationality should take into account three constraints about what a "good reason" in scientific matters is, constraints that shape the practical identity and the normative face of science: the constraints of publicity, reliability and reflective authority.

There has been much discussion concerning the consequences of 'going natural', i.e., of replacing a priori epistemology with empirical psychology. Traditionalists claim that a naturalized epistemology is not viable—to eliminate the normative from an account of knowledge is to cease to do epistemology at all. Naturalists claim that a naturalized account is the only viable one—assuming, in step with the urgings of Quine, that there are no standards independent of (and external to) science, science itself must act as the sole (...) epistemic norm. In the wake of the above debate some epistemologists have attempted to argue in favor of, and develop, a middle-ground position— normative naturalism . Such a position is intended to be consistent with the naturalist's intuition that the traditional search for a 'first philosophy'is misguided and consistent with the traditionalist's intuition that a complete elimination of the normative would leave epistemology impotent. In this paper I will examine one argument in favor of a normative naturalism . / will show that such a proposal is inherently problematic and argue that naturalism and normativity are mutually exclusive concepts. Therefore, I suggest that, even in the 'age of cognitive science', epistemologists continue to do traditional epistemology by attempting to develop, a priori , the general criteria for determining the justificatory status of our (scientific) beliefs.
