Fringe science has been an important topic since the start of the revolution in the social studies of science that occurred in the early 1970s. The revolution was what Collins and Evans refer to as the "second wave of science studies," while this paper is best thought of as an exercise in "third wave science studies." The first wave was that period which reached its apogee in the aftermath of the Second World War when science was seen as unquestionably the (...) pre-eminent form of knowledge-making, and the role of philosophy and sociology was to understand how it was so and how societies could be arranged to nurture it best; the second wave was "social constructionism" which became folded into post-modernism in...

Decades of debate about scientific realism notwithstanding, we find ourselves bemused by what different philosophers appear to think it is, exactly. Does it require any sort of belief in relation to scientific theories and, if so, what sort? Is it rather typified by a certain understanding of the rationality of such beliefs? In the following dialogue we explore these questions in hopes of clarifying some convictions about what scientific realism is, and what it could or should be. En route, we (...) encounter some profoundly divergent conceptions of the nature of science and of philosophy. (shrink)

In The empirical stance, Bas van Fraassen argues for a reconceptualization of empiricism, and a rejection of its traditional rival, speculative metaphysics, as part of a larger and provocative study in epistemology. Central to his account is the notion of voluntarism in epistemology, and a concomitant understanding of the nature of rationality. In this paper I give a critical assessment of these ideas, with the ultimate goal of clarifying the nature of debate between metaphysicians and empiricists, and more specifically, between (...) scientific realists and empiricist antirealists. Despite van Fraassen’s assertion to the contrary, voluntarism leads to a form of epistemic relativism. Rather than stifling debate, however, this ‘stance’ relativism places precise constraints on possibilities for constructive engagement between metaphysicians and empiricists, and thus distinguishes, in broad terms, paths along which this debate may usefully proceed from routes which offer no hope of progress.

RÉSUMÉDans Scientific Ontology: Integrating Naturalized Metaphysics and Voluntarist Epistemology, je soutiens que les convictions ontologiques associées à la recherche scientifique sont imprégnées de convictions philosophiques. Les interprétations de l'ontologie scientifique impliquent ce que j'appelle des inférences métaphysiques et, qui plus est, il existe différentes façons de faire ces inférences sur la base de positions épistémiques différentes, mais néanmoins rationnelles. Si cette analyse est juste, elle problématise toute distinction nette entre la métaphysique naturalisée et les autres types de métaphysique, et dissout (...) toute présomption qu'il existe une seule bonne réponse aux questions ontologiques liées aux sciences. Dans cet article, je considère quelques-uns des importants défis qu'Amanda Bryant, Stathis Psillos et Matthew Slater posent à l'endroit de ces affirmations. (shrink)

I introduce the symposium on Anjan Chakravartty’s Scientific Ontology by summarizing the book’s main claims. In my commentary, I first challenge Chakravartty’s claim that naturalized metaphysics cannot be indexed to science simpliciter. Second, I argue that there are objective truths regarding what conduces to particular epistemic aims, and that Chakravartty is therefore too permissive regarding epistemic stances and their resultant ontologies. Third, I argue that it is unclear what stops epistemic stances from having unlimited influence. Finally, I argue that Chakravartty’s (...) epistemic stance voluntarism is inadequately motivated and lacks empirical support for its psychological content. (shrink)

Van Fraassen has argued that many philosophical positions should be understood as stances rather than factual beliefs. In this paper I discuss the vexed question of whether and how such stances can be rationally justified. Until this question has been satisfactorily answered, the otherwise promising stance approach cannot be considered a viable metaphilosophical option. One can find hints, and the beginnings of an answer to this question, in van Fraassen’s (and others’) writings, but no general, fully clear and convincing account (...) has been offered. I aim to provide such an account. In the first section I introduce the concept of a stance. In the second section I argue that stances may be justified pragmatically, in terms of both their epistemic fruits, and their coherence with values. In the third section I further consider the relationship between stances and values, arguing that the value-ladenness of a stance does not render it immune to rational scrutiny. In the final section I look at van Fraassen’s version of epistemological voluntarism, which plays a central role in his conception of the basis on which a stance may be rationally adopted. I show that voluntarism provides a theoretical framework, and approach to epistemology, within which the forms of justification appropriate to stance choice I outline in sections 2 and 3 find a natural home.

Pseudoscience spreads through communicative and inferential processes that make people vulnerable to weird beliefs. However, the fact that pseudoscientific beliefs are unsubstantiated and have no basis in reality does not mean that the people who hold them have no reasons for doing so. We propose that, reasons play a central role in the diffusion of pseudoscience. On the basis of cultural epidemiology and the interactionist theory of reasoning, we will here analyse the structure and the function of reasons in the (...) propagation of pseudoscience. We conclude by discussing the implications of our approach for the understanding of human irrationality. (shrink)

This article is aimed at contributing to the study of the relationship that new religious movements entertain with technology and science. It focuses on an object that is central in Scientology's teachings and practice: the Electropsychometer or E-meter. In interaction with the general public, such as in a 2014 TV Super Bowl advertisement, Scientology seems to claim a unique relationship with science and technology in the form of a “combination” and a “connection” evoked while displaying this very E-meter. Hence, exploring (...) the teachings related to it is relevant in order to understand how such combination or connection is conceptualized. (shrink)

Voluntarism about beliefs is the view that persons can be free to choose their beliefs for non-epistemic (truth-related) reasons (cf. Williams 1973). One problem for belief voluntarism is that it can lead to Moore-paradoxality. The person might believe that -/- a.) there are also good epistemic reasons for her belief, or that b.) there are no epistemic reasons one way or the other, or that c.) there are good epistemic reasons against her belief. -/- If the person is aware of (...) the fact that she chose her belief for non-epistemic reasons, then she would believe one of the following three things (using "evidence" as a term for all kinds of epistemic reasons): -/- a.) I believe that p but not because of the good evidence in favour of it; b.) I believe that p but that has nothing to do with the evidence; c.) I believe that p but the evidence speaks against it. -/- We could add a fourth case in which the person suspends belief on the subject matter despite the evidence: -/- d.) The evidence supports "p" but I have no view on the matter. -/- All the different versions a-d are somehow Moore-paradoxical. They constitute different ways of mistrusting one's own belief (cf. Wittgenstein 1958, p.190). Given that one cannot, for conceptual reasons, mistrust one's beliefs, it follows that a person cannot be in one of the above predicaments described by a-d. Hence, voluntarism about beliefs is false, at least if we are dealing with cases in which the person is aware of the fact that she chose her belief for non-epistemic reasons. It won't help to focus on cases in which the person is not aware of that fact, either because she has forgotten the genesis of her belief or because the process of belief acquisition was unconscious. -/- Bas van Fraassen's conception of a stance (cf. van Fraassen 2002)-a mix of commitments, values, goals-gives us reason to rethink the possibility of voluntarism. Might we be free to choose our stances for non-epistemic reasons? I argue here that the answer is negative. First, it is not clear at all whether stances can be objects of choice, properly speaking. And: Can we make sense of the idea of a free choice here? Furthermore, I argue that similar problems of Moore-paradoxality would arise for voluntarism about stances. If one does not want to completely devalue the idea of a stance, one should avoid voluntarism. (shrink)

What is it about relativism that justifies, or at least explains, its continued appeal in the face of relentless attacks through the history of philosophy? This paper explores a new answer to this old question, casting the response in metaphilosophical terms. § i introduces the problem. § ii argues that one part of the answer is that some of the well-known defences of relativism take it to be a philosophical stance—that is, a broad perspective or orientation with normative consequences—rather than (...) a doctrine or a thesis. § iii draws attention to an assumption, not always explicitly stated by its proponents, that the relativist stance leads to the cultivation of some key intellectual virtues. Open-mindedness, tolerance, intellectual humility, and curiosity are examples of the intellectual virtues that relativism can foster. § iv argues that the defence of relativism on the basis of the virtues that are assumed to follow from it, at best, is only partially successful. Moreover, there is a range of epistemic vices, resulting from the stance, that undercuts the virtue-based defence presented in § iii. (shrink)

This book argues that the only kind of metaphysics that can contribute to objective knowledge is one based specifically on contemporary science as it really is, and not on philosophers' a priori intuitions, common sense, or simplifications of science. In addition to showing how recent metaphysics has drifted away from connection with all other serious scholarly inquiry as a result of not heeding this restriction, this book demonstrates how to build a metaphysics compatible with current fundamental physics, which, when combined (...) with metaphysics of the special sciences, can be used to unify physics with the other sciences without reducing these sciences to physics itself. Taking science metaphysically seriously, this book argues, means that metaphysicians must abandon the picture of the world as composed of self-subsistent individual objects, and the paradigm of causation as the collision of such objects. The text assesses the role of information theory and complex systems theory in attempts to explain the relationship between the special sciences and physics, treading a middle road between the grand synthesis of thermodynamics and information, and eliminativism about information. The consequences of the books' metaphysical theory for central issues in the philosophy of science are explored, including the implications for the realism versus empiricism debate, the role of causation in scientific explanations, the nature of causation and laws, the status of abstract and virtual objects, and the objective reality of natural kinds.

In Systematicity, Paul Hoyningen-Huene answers the question "What is science?" by proposing that scientific knowledge is primarily distinguished from other forms of knowledge, especially everyday knowledge, by being more systematic. "Science" is here understood in the broadest possible sense, encompassing not only the natural sciences but also mathematics, the social sciences, and the humanities. The author develops his thesis in nine dimensions in which it is claimed that science is more systematic than other forms of knowledge: regarding descriptions, explanations, predictions, (...) the defense of knowledge claims, critical discourse, epistemic connectedness, an ideal of completeness, knowledge generation, and the representation of knowledge. He compares his view with positions on the question held by philosophers from Aristotle to Nicholas Rescher. The book concludes with an exploration of some consequences of Hoyningen-Huene's view concerning the genesis and dynamics of science, the relationship of science and common sense, normative implications of the thesis, and the demarcation criterion between science and pseudo-science.

While scientific pluralism enjoys widespread popularity within the philosophy of science, a related position, epistemic relativism, does not have much traction. Defenders of scientific pluralism, however, dread the question of whether scientific pluralism entails epistemic relativism. It is often argued that if a scientific pluralist accepts epistemic relativism, she will be unable to pass judgment because she believes that “anything goes”. In this article, I will show this concern to be unnecessary. I will also argue that common strategies to differentiate (...) relativism and pluralism fail. Building upon this analysis, I will propose a new way of looking at both positions’ relations. This article aims to understand what explains the friction between scientific pluralism and epistemic relativism. I will demonstrate that conceptualizing both epistemic relativism and scientific pluralism as “stances” sheds better light on their relation and demonstrates that it is, in principle, possible to support both positions at the same time. Preferred policies and levels of analysis, however, cause friction in practice. (shrink)

William Whewell’s 19th century philosophy of science is sometimes glossed over as a footnote to Kant. There is however a key feature of Whewell’s account worth noting. This is his appeal to Aristotle’s form/matter hylomorphism as a metaphor to explain how mind and world merge in successful scientific inquiry. Whewell’s hylomorphism suggests a middle way between rationalism and empiricism reminiscent of experience pragmatists like Steven Levine’s view that mind and world are entwined in experience. I argue however that Levine does (...) not adequately explain exactly how mind and world entwine. He could nonetheless do so if he appealed to Whewell’s hylomorphic metaphor. We may prefer a reductive metaphysical explanation, but I suggest that pragmatists only have recourse to metaphor in this case. Both reductive and metaphorical explanations can enjoy great explanatory power if they exhibit a suitable measure of what I will call sematic distance. Semantic distance measures how close or how far apart explanandum and explanans are from each other in meaning. Metaphorical explanation - as evident in Whewell’s hylomorphism and as detailed via the notion of semantic distance - presents a valuable new explanatory tool to those who hold that mind and world are entwined sans recourse to metaphysics.

Some versions of empiricism have been accused of being neither empirically confirmable nor analytically true and therefore meaningless or unknowable by their own lights. Carnap, and more recently van Fraassen, have responded to this objection by construing empiricism as a stance containing non-cognitive attitudes. The resulting stance empiricism is not subject to the norms of knowledge, and so does not self-defeat as per the objection. In response to this proposal, several philosophers have argued that if empiricism is a stance, then (...) there can be no distinctively epistemic reasons in favor of adopting it, but only prudential or moral reasons. I defend stance empiricism against this objection by showing that stance empiricism furthers many plausibly epistemic goals, such as false belief avoidance, wisdom, and justification. I respond to three objections to my argument: that I assume a conception of epistemic reason that leads to problematic tradeoffs, that to have epistemic reason is just to be epistemically justified, and that my premise that experience is the only source of information has no empirical content. (shrink)

This paper makes three points: First, empiricism as a stance is problematic unless criteria for evaluating the stance are provided. Second, Van Fraassen conceives of the empiricist stance as receiving its content, at least in part, from the rejection of metaphysics. But the rejection of metaphysics seems to presuppose for its justification the very empiricist doctrine Van Fraassen intends to replace with the empiricist stance. Third, while I agree with Van Fraassen’s endorsement of voluntarism, I raise doubts about the possibility (...) of defending voluntarism without engaging in the kind of metaphysics Van Fraassen rejects.

RÉSUMÉJe soulève des questions concernant l'approche volontariste défendue par Chakravartty à l’égard des positions : supposant que nous reconnaissons une hiérarchie des positions, la position volontariste peut être à la fois vraie et trompeuse en ce qui concerne la viabilité pratique de certains débats dans le domaine de la philosophie des sciences, en particulier le débat sur le réalisme scientifique ou sur la façon de «naturaliser» la métaphysique.

This paper presents a naturalistic response to the challenge of epistemic relativism. The case of the Azande poison oracle is employed as an example of an alternative epistemic norm which may be used to justify beliefs about everyday occurrences. While a distinction is made between scepticism and relativism, an argument in support of epistemic relativism is presented that is based on the sceptical problem of the criterion. A response to the resulting relativistic position is then provided on the basis of (...) a particularist response to scepticism combined with a naturalistic approach to the warrant of epistemic norms. It is argued that it is possible to comparatively assess the ability of epistemic norms to lead to epistemic aims. As against the epistemic relativist, it is possible to provide an objective basis for the choice between alternative epistemic norms. (shrink)

This paper explores the relationship between scepticism and epistemic relativism in the context of recent history and philosophy of science. More specifically, it seeks to show that significant treatments of epistemic relativism by influential figures in the history and philosophy of science draw upon the Pyrrhonian problem of the criterion. The paper begins with a presentation of the problem of the criterion as it occurs in the work of Sextus Empiricus. It is then shown that significant treatments of epistemic relativism (...) in recent history and philosophy of science (critical rationalism, historical philosophy of science and the strong programme) draw upon the problem of the criterion. It is briefly suggested that a particularist response to the problem of the criterion may be put to good use against epistemic relativism. (shrink)

I criticize conceptual pluralism, as endorsed recently by John Dupre and Philip Kitcher, for failing to supply strategies for demarcating science from non-science. Using creation-science as a test case, I argue that pluralism blocks arguments that keep creation-science in check and that metaphysical pluralism offers it positive, metaphysical support. Logical empiricism, however, still provides useful resources to reconfigure and manage the problem of creation-science in those practical and political contexts where pluralism will fail.

Modern empiricism has been conditioned in large part by two dogmas. One is a belief in some fundamental cleavage between truths which are analytic, or grounded in meanings independently of matters of fact, and truth which are synthetic, or grounded in fact. The other dogma is reductionism: the belief that each meaningful statement is equivalent to some logical construct upon terms which refer to immediate experience. Both dogmas, I shall argue, are ill founded. One effect of abandoning them is, as (...) we shall see, a blurring of the supposed boundary between speculative metaphysics and natural science. Another effect is a shift toward pragmatism. (shrink)

RÉSUMÉDans cette contribution, les points fondamentaux du livre d'Anjan Chakravartty, Scientific Ontology, sont discutés de manière critique. Après une brève présentation du projet d'une ontologie dite «stance-based», je critique la manière dont Chakravartty conçoit l'inférence métaphysique. Puis, dans la section 4, je conteste l'opinion de Chakravartty selon laquelle les débats fondamentaux en métaphysique conduisent inévitablement à un désaccord insoluble. La section 5 examine le concept de position épistémique et relève les problèmes inhérents à la manière dont Chakravartty conçoit la rationalité (...) de la sélection d'une position. Finalement, la section 6 concerne les implications d'une ontologie qui serait basée sur les positions épistémiques pour le débat sur le réalisme scientifique. (shrink)

Bas van Fraassen wants to be an empiricist, but he is deeply dissatisfied with traditional versions of empiricism. So he is developing a new approach: epistemological voluntarism. Let me be blunt. Van Fraassen is an outstanding philosopher, and his new epistemology is important. But The Empirical Stance is a difficult book, because voluntarism is a difficult position to articulate. In what follows I attempt to clarify the situation a little, or at least to explain why it resists clarification.

This paper reviews how research on the demarcation problem has developed, starting from Popper’s criterion of falsifiability and ending with recent naturalistically oriented approaches. The main differences between traditional and contemporary approaches to the problem are explicated in terms of six postulates called the traditional assumptions. It is argued that all of the assumptions can be dismissed without giving up on the demarcation problem and that doing so might benefit further discussions on pseudoscience. Four present-day research movements on evaluating the (...) boundaries of science are introduced: (1) philosophy of pseudoscience, (2) social epistemology of dissent, (3) agnotology, and (4) evaluation of expertise. Researchers working within these areas have abandoned some or all traditional assumptions. (shrink)

I argue for two claims: that the ordinary English truth predicate is a gradable adjective and that truth is a property that comes in degrees. The first is a semantic claim, motivated by the linguistic evidence and the similarity of the truth predicate’s behavior to other gradable terms. The second is a claim in natural language metaphysics, motivated by interpreting the best semantic analysis of gradable terms as applied to the truth predicate. In addition to providing arguments for these two (...) claims, I draw out consequences for debates about deflationism and truth-based analyses of notions such as assertion and logical consequence.

Van Fraassen maintains that the information that we canglean from experience is limited to those entities and processes that are detectable bymeans of our unaided senses. His challenge to the realist, I suggest, is that the attemptto inferentially transcend those limits amounts to a reversion to rationalism. Under pressurefrom such examples as microscopic observation, he has recently widened the scope of thephenomena to include object-like experiences without empirical objects of experience.With this change in mind, I argue that van Fraassen needs (...) an account of perception whoseconsequence is that we can only see what we see with the unaided eye. I then argue thatreflection on the epistemically significant aspects of the perceptual process rendersvan Fraassen's characterization of the limits of experience implausible; technologicallyenhanced perception brings ``unobservables'' within those limits. An empiricismthat is compatible with realism results. (shrink)

After a review of previous uses of the term “pseudotechnology”, a definition is proposed: “A pseudotechnology is an alleged technology that is irreparably dysfunctional for its intended purpose since it is based on construction principles that cannot be made to work”. The relationship between pseudotechnology and pseudoscience is discussed, and so is the relationship between pseudotechnology and the much weaker concept of technological malfunction. An explanation is offered of why pseudotechnology is much more seldom referred to than pseudoscience: dysfunctional technology (...) usually reveals itself when put to use, whereas dysfunctional science tends to be more difficult to disclose.

The problem of demarcating science from nonscience remains unsolved. This article executes an analytical process of elimination of different demarcation proposals put forward since the professionalization of the philosophy of science, explaining why each of those proposals is unsatisfactory or incomplete. Then, it elaborates on how to execute an alternative multicriterial scientific demarcation project put forward by Mahner. This project allows for the demarcation not only of science from non-science and from pseudoscience, but also of different types of sciences and (...) of scientific fields from each other. This article also offers arguments in favor of accepting two types of scientific demarcations, namely epistemic-warrant scientific demarcations and territorial scientific demarcations, and argues in favor of accepting a territorially broad scientific demarcation.

Scientific realism, the position that successful theories are likely to be approximately true, is threatened by the pessimistic induction according to which the history of science is full of suc- cessful, but false theories. I aim to defend scientific realism against the pessimistic induction. My main thesis is that our current best theories each enjoy a very high degree of predictive success, far higher than was enjoyed by any of the refuted theories. I support this thesis by showing that both (...) the amount, and quality, of scientific evidence has increased enormously in the recent past, resulting in a big boost of success for the best theories.

Using astrology as a case study, this paper attempts to establish a criterion for demarcating science from pseudoscience. Numerous reasons for considering astrology to be a pseudoscience are evaluated and rejected; verifiability and falsifiability are briefly discussed. A theory is said to be pseudoscientific if and only if (1) it has been less progressive than alternative theories over a long period of time, and faces many unsolved problems, but (2) the community of practitioners makes little attempt to develop the theory (...) towards solutions of the problems, shows no concern for attempts to evaluate the theory in relation to others, and is selective in considering confirmations and disconfirmations. This criterion has the interesting consequence that a theory can be scientific at one time but pseudoscientific at another. (shrink)
