This paper examines our pre-theoretic conception of non-supernaturalism; the thesis that all that exists is natural. It is argued that we intuitively take this thesis to be a substantive, non-dogmatic, empirically justified, not merely contingent truth. However, devicing an interpretation of non-supernaturalism that captures all aspects of this intuition is difficult. Indeed, it is found that this intuition conflates the strong inferential scope of a metaphysical claim with the modest justificatory requirements of an empirical matter of fact. As such, non-supernaturalism, (...) in itspre-theoreticform, contains an internal tension that must be navigated whenever the thesis features in systematic thinking. (shrink)

O título deste paper conecta duas palavras, frequentemente aplicadas ao pensamento de Nietzsche, mas usualmente não de forma simultânea, dado que perspectivismo e naturalismo são frequentemente vistos como conceitos alternativos, ou mesmo contraditórios. Enquanto perspectivismo é associado a leituras estéticas, construtivistas, kantianas e mesmo relativistas e pós-modernas de Nietzsche, a noção de naturalismo o aproxima da ciência, do empirismo e do realismo. Por esta razão, muitos dos que atribuem a Nietzsche versões de perspectivismo abrigam reservas com relação a leituras naturalistas (...) e vice versa. Esse paper, todavia, argumenta que Nietzsche não defende ou desenvolve abertamente ‘naturalismo’ ou ‘perspectivismo’ na forma de doutrinas ou teorias. Devemos ser relutantes em aplicar denominadores, aparentemente tão estreitos a sua filosofia, haja vista poderem muito bem ser, fundamentalmente, enganadores. Ademais, tais abordagens tendem a resultar em preconceitos confirmados ao invés de novas ideias. Então, com relação a questão de se Nietzsche deve ser chamado de um ‘naturalista’, me parece que a maldade [evil] tem peso consideravelmente maior do que a necessidade, nesse caso. Nietzsche não ensina doutrinas mas exemplifica, testa e propõe certas práticas filosóficas, sendo que essas sim contêm características naturalistas e perspectivísticas. Ele convida o seu leitor a adotar perspectivas naturalistas e as explora experimentalmente nos seus respectivos contextos práticos a fim de perseguir um dado projeto. As abordagens naturalizantes de Nietzsche da mente, filosofia e ciência, seu aparente empirismo, sensualismo e materialismo são sempre contrapesados por uma epistemologia crítica. (shrink)

At some point in America in the 1940s, T. D. Lysenko's neo-Lamarckian hereditary theories transformed from a set of disputed doctrines into a prime exemplar of "pseudoscience." This paper explores the context in which this theory acquired this pejorative status by examining American efforts to refute Lysenkoism both before and after the famous August 1948 endorsement of Lysenko's doctrines by the Stalinist state, with particular attention to the translation efforts of Theodosius Dobzhansky. After enumerating numerous tactics for combating perceived pseudoscience, (...) the Lysenko case is then juxtaposed with another American case of alleged pseudoscience: the notorious 1950 scandal surrounding Immanuel Velikovsky's Worlds in Collision (1950, Worlds in Collision. New York: Macmillan). On several levels, the characterization of Lysenkoism as pseudoscientific served as a template for casting other rejected theories, including Velikovsky's, in the same light.

The modern abundance and prominence of data have led to the development of “data science” as a new field of enquiry, along with a body of epistemological reflections upon its foundations, methods, and consequences. This article provides a systematic analysis and critical review of significant open problems and debates in the epistemology of data science. We propose a partition of the epistemology of data science into the following five domains: (i) the constitution of data science; (ii) the kind of enquiry (...) that it identifies; (iii) the kinds of knowledge that data science generates; (iv) the nature and epistemological significance of “black box” problems; and (v) the relationship between data science and the philosophy of science more generally.

The replication or reproducibility crisis in psychological science has renewed attention to philosophical aspects of its methodology. I provide herein a new, functional account of the role of replication in a scientific discipline: to undercut the underdetermination of scientific hypotheses from data, typically by hypotheses that connect data with phenomena. These include hypotheses that concern sampling error, experimental control, and operationalization. How a scientific hypothesis could be underdetermined in one of these ways depends on a scientific discipline’s epistemic goals, theoretical (...) development, material constraints, institutional context, and their interconnections. I illustrate how these apply to the case of psychological science. I then contrast this “bottom-up” account with “top-down” accounts, which assume that the role of replication in a particular science, such as psychology, must follow from a uniform role that it plays in science generally. Aside from avoiding unaddressed problems with top-down accounts, my bottom-up account also better explains the variability of importance of replication of various types across different scientific disciplines.

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.

This article analyses the epistemic status of law and its presumption of being a science in relation with the so-called demarcation criterion proposed by different philosophers of science. Such criteria are the main analytical elements to differentiate scientific discourses from those who are not and the ones who pretend to be. In relation to those, pseudoscience and law are treated, to finally conclude with the exposition of the case of Daubert v. Merrill Dow Pharmaceuticals, in which a judicial process defined (...) demarcation criteria. This paper shows how the demarcation criteria of science and the concept of pseudoscience cannot be applied to law science given its own rationality. (shrink)

In this paper, I argue that Imre Lakatos’s account on the relation between the history and the philosophy of science, if properly understood and also if properly modified, can be valuable for the philosophical comprehension of the relation between the history and the philosophy of science. The paper is divided into three main parts. In the first part, I provide a charitable exegesis of the Lakatosian conception of the history of science in order to show that Lakatos’s history cannot be (...) a caricature. In the second part, I describe what I believe are the real problems of Lakatos’s account on a metaphysical and on a methodological level. In order to address these problems, I take advantage of the recent critique of the so-called “confrontation model”. Finally, in the third part, I suggest that a proper modification of Lakatos’s perspective can resolve the aforementioned problems without distorting Lakatos’s central aspiration, which is that the philosophical theories of scientific rationality can be assessed with the help of the history of science without losing their normative content.

In this paper I will argue that a profile of the pseudo-sciences can be gained from the scientific pretensions of the pseudo-scientist. These pretensions provide two yardsticks which together take care of the charge of scientific prejudice that any suggested demarcation of pseudo-science has to face. To demonstrate that my analysis has teeth I will apply it to Freud and modern-day Bach-kabbalists. Against Laudan I will argue that the problem of demarcation is not a pseudo-problem, though the discussion will bear (...) out that Laudan's replacement question, namely the question whether someone's theory is well-confirmed, is not, as Lugg claimed, independent of the question as to whether that person is a pseudo-scientist. I further argue that my prototype pseudo-scientists do not have the shortcomings highlighted in Thagard's recent analysis of pseudo-science. (shrink)

Many philosophers have come to believe there is no single criterion by which one can distinguish between a science and a pseudoscience. But it need not follow that no distinction can be made: a multifactorial account of what constitutes a pseudoscience remains possible. On this view, knowledge-seeking activities fall on a spectrum, with the clearly scientific at one end and the clearly non-scientific at the other. When proponents claim a clearly non-scientific activity to be scientific, it can be described as (...) a pseudoscience. One feature of a scientific theory is that it forms part of a research tradition being actively pursued by a scientific community. If a theory lacks this form of epistemic warrant, this is a pro tanto reason to regard it as pseudoscientific. (shrink)

Pseudoproblems, pseudoquestions, pseudosentences (etc.) constitute an iridescent group of concepts which were prominently used by the Vienna Circle (including Wittgenstein). In the course of an explication this paper presents a compilation of the many different meanings that were given to these expressions. This includes the more prominent Viennese approaches as well as a more recent one by Roy Sorensen. A novel proposal concerning the use ofthe term is made, suggesting that nothing is just a pseudoproblem, but only relative to a (...) certain state of discourse. While the paper follows an explicative methodology, several uses of 'pseudoproblem', including the explicated one, relate pseudoproblemhood to other kinds of analysis. (shrink)

It has been suggested that the enterprise of developing mechanistic theories of the human cognitive architecture is flawed because the theories produced are not directly falsifiable. Newell attempted to sidestep this criticism by arguing for a Lakatosian model of scientific progress in which cognitive architectures should be understood as theories that develop over time. However, Newell's own candidate cognitive architecture adhered only loosely to Lakatosian principles. This paper reconsiders the role of falsification and the potential utility of Lakatosian principles in (...) the development of cognitive architectures. It is argued that a lack of direct falsifiability need not undermine the scientific development of a cognitive architecture if broadly Lakatosian principles are adopted. Moreover, it is demonstrated that the Lakatosian concepts of positive and negative heuristics for theory development and of general heuristic power offer methods for guiding the development of an architecture and for evaluating the contribution and potential of an architecture's research program. (shrink)

Cognitive architectures - task-general theories of the structure and function of the complete cognitive system - are sometimes argued to be more akin to frameworks or belief systems than scientific theories. The argument stems from the apparent non-falsifiability of existing cognitive architectures. Newell was aware of this criticism and argued that architectures should be viewed not as theories subject to Popperian falsification, but rather as Lakatosian research programs based on cumulative growth. Newell's argument is undermined because he failed to demonstrate (...) that the development of Soar, his own candidate architecture, adhered to Lakatosian principles. This paper presents detailed case studies of the development of two cognitive architectures, Soar and ACT-R, from a Lakatosian perspective. It is demonstrated that both are broadly Lakatosian, but that in both cases there have been theoretical progressions that, according to Lakatosian criteria, are pseudo-scientific. Thus, Newell's defense of Soar as a scientific rather than pseudo-scientific theory is not supported in practice. The ACT series of architectures has fewer pseudo-scientific progressions than Soar, but it too is vulnerable to accusations of pseudo-science. From this analysis, it is argued that successive versions of theories of the human cognitive architecture must explicitly address five questions to maintain scientific credibility. (shrink)

There is overwhelming agreement amongst naturalists that a naturalistic ontology should not allow for the possibility of supernatural entities. I argue, against this prevailing consensus, that naturalists have no proper basis to oppose the existence of supernatural entities. Naturalism is characterized, following Leiter and Rea, as a position which involves a primary commitment to scientific methodology and it is argued that any naturalistic ontological commitments must be compatible with this primary commitment. It is further argued that properly applied scientific method (...) has warranted the acceptance of the existence of supernatural entities in the past and that it is plausible to think that it will do so again in the future. So naturalists should allow for the possibility of supernatural entities. (shrink)

What, if anything, is wrong with conspiracy theories? A conspiracy refers to a group of people acting in secret to achieve some nefarious goal. Given that the pages of history are full of such plots, however, why are CTs often regarded with suspicion and even disdain? According to “particularism,” the currently dominant view among philosophers, each CT should be evaluated on its own merits and the negative reputation of CTs as a class is wholly undeserved. In this paper, I defend (...) a moderate version of “generalism,” the view that there is indeed something prima facie suspicious about CTs, properly defined, and that they suffer from common epistemic defects. To demarcate legitimate theorizing about real-life conspiracies from “mere conspiracy theories”, I draw on a deep asymmetry between causes and effects in the natural world. Because of their extreme resilience to counterevidence, CTs can be seen as the epistemological equivalent of black holes, in which unwary truth-seekers are drawn, never to escape. Finally, by presenting a generic “recipe” for generating novel CTs around any given event, regardless of the circumstances and the available evidence, I rescue the intuitions beneath colloquial phrases like “That's just a conspiracy theory.”.

An immunizing strategy is an argument brought forward in support of a belief system, though independent from that belief system, which makes it more or less invulnerable to rational argumentation and/or empirical evidence. By contrast, an epistemic defense mechanism is defined as a structural feature of a belief system which has the same effect of deflecting arguments and evidence. We discuss the remarkable recurrence of certain patterns of immunizing strategies and defense mechanisms in pseudoscience and other belief systems. Five different (...) types will be distinguished and analyzed, with examples drawn from widely different domains. The difference between immunizing strategies and defense mechanisms is analyzed, and their epistemological status is discussed. Our classification sheds new light on the various ways in which belief systems may achieve invulnerability against empirical evidence and rational criticism, and we propose our analysis as part of an explanation of these belief systems’ enduring appeal and tenacity.

In recent controversies about Intelligent Design Creationism (IDC), the principle of methodological naturalism (MN) has played an important role. In this paper, an often neglected distinction is made between two different conceptions of MN, each with its respective rationale and with a different view on the proper role of MN in science. According to one popular conception, MN is a self-imposed or intrinsic limitation of science, which means that science is simply not equipped to deal with claims of the supernatural (...) (Intrinsic MN or IMN). Alternatively, we will defend MN as a provisory and empirically grounded attitude of scientists, which is justified in virtue of the consistent success of naturalistic explanations and the lack of success of supernatural explanations in the history of science (Provisory MN or PMN). Science does have a bearing on supernatural hypotheses, and its verdict is uniformly negative. We will discuss five arguments that have been proposed in support of IMN: the argument from the definition of science, the argument from lawful regularity, the science stopper argument, the argument from procedural necessity, and the testability argument. We conclude that IMN, because of its philosophical flaws, proves to be an ill-advised strategy to counter the claims of IDC. Evolutionary scientists are on firmer ground if they discard supernatural explanations on purely evidential grounds, instead of ruling them out by philosophical fiat. (shrink)

For a long time, philosophers of science have expressed little interest in the so-called demarcation project that occupied the pioneers of their field, and most now concur that terms like “pseudoscience” cannot be defined in any meaningful way. However, recent years have witnessed a revival of philosophical interest in demarcation. In this paper, I argue that, though the demarcation problem of old leads to a dead-end, the concept of pseudoscience is not going away anytime soon, and deserves a fresh look. (...) My approach proposes to naturalize and down-size the concept, anchoring it in real-life doctrines and fields of inquiry. First, I argue against the definite article “the” in “the demarcation problem”, distinguishing between territorial and normative demarcation, and between different failures and shortcomings in science apart from pseudoscience. Next, I argue that pseudosciences can be fruitfully regarded as simulacra of science, doctrines that are not epistemically warranted but whose proponents try to create the impression that they are. In this element of imitation or mimicry, I argue, lies the clue to their common identity. Despite the huge variety of doctrines and beliefs gathered under the rubric of “pseudoscience”, and the wide range of defects from which they suffer, pseudosciences all engage in similar strategies to create an impression of epistemic warrant. The indirect, symptomatic approach defended here leads to a general characterization of pseudosciences in all domains of inquiry, and to a useful diagnostic tool. (shrink)

Larry Laudan v článku z roku 1983 označil problém demarkace, tj. rozlišení „vědy" a „pseudovědy", za filosofický pseudoproblém, kterým není třeba se zabývat, a slova „vědecké" a „pseudovědecké" za prázdné pojmy, které můžeme z našeho slovníku zcela vyškrtnout. V předkládané studii zpochybňuji toto Laudanovo stanovisko a předkládám argumenty ve prospěch tvrzení, že 1) rozlišení vědy a pseudovědy představuje důležitý a aktuální problém, kterým je třeba se zabývat, a že 2) možný způsob řešení tohoto problému nabízejí současná sociální studia vědy. Jejich (...) východiskem je pojetí vědy jako „formy života" a pojetí demarkačního kritéria jako proměnlivého souboru charakteristik, který sice nelze jednoznačně definovat, ale přesto jej lze zkoumat, a to prostřednictvím sociologické analýzy vědecké praxe. Mým záměrem je na příkladu několika vzorových studií představit specifika sociologického přístupu z hlediska jeho metodologie i povahy nabízených řešení a zhodnotit jeho možnosti i omezení pro filosofii vědy.

There have been persistent philosophical efforts to demarcate the province of science. Fewer attempts have been made to explore whether these demarcation strategies are consistent with the liberal promise of religious neutrality. Within this framework, most liberal political theorists seem to agree that hypotheses suggesting supernatural agency should remain outside the purview of science by principle. In their view, this rule of methodological naturalism is neutral in the relevant sense, since it is silent towards ultimate questions. This paper examines whether (...) this is so, especially when discussing the content of the science curriculum in public education. In this context, advocates of the status of Intelligent Design creationism as a scientific theory argue that MN arbitrarily dismisses a type of supernatural agency that is fundamental to several branches of theistic belief. Drawing on Thomas Nagel’s position, the paper contends that MN assumes a meta-scientific position to which either god does not exist, or god does not intervene in cosmic history. To that extend, MN cannot be reconciled with LPRN. However, this conclusion does not entail that hypotheses that suggest supernatural agency must be included in the science curriculum. Creationist theories may remain excluded to the extent that they fall short of the standards that are required for a proficient scientific account. But, crucially, it will not be their religious character what keeps them out of the classroom, but a series of pseudoscientific wrongs which are non-exclusive to supernaturalistic hypotheses. The paper thus suggests the exploration of an alternative demarcation strategy, one that is consistent with LPRN. (shrink)

Fleck's Genesis and Development of a Scientific Fact foregrounds claims traditionally excluded from reception, often regarded as opposed to fact, scientific claims that are increasingly seldom discussed in connection with philosophy of science save as examples of pseudoscience.

Stephen Turner defends the sociopolitical role that experts—mainly but not only of the scientific kind—play in modern democratic society and explores means for increasing the rationality of their employment. Laudable though this is, at times Turner goes into more detail than democratic principles require; in his enthusiasm for rationality, he aims at levels of adequacy that are not always within the grasp of democracy.

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.

This inaugural handbook documents the distinctive research field that utilizes history and philosophy in investigation of theoretical, curricular and pedagogical issues in the teaching of science and mathematics. It is contributed to by 130 researchers from 30 countries; it provides a logically structured, fully referenced guide to the ways in which science and mathematics education is, informed by the history and philosophy of these disciplines, as well as by the philosophy of education more generally. The first handbook to cover the (...) field, it lays down a much-needed marker of progress to date and provides a platform for informed and coherent future analysis and research of the subject. -/- The publication comes at a time of heightened worldwide concern over the standard of science and mathematics education, attended by fierce debate over how best to reform curricula and enliven student engagement in the subjects There is a growing recognition among educators and policy makers that the learning of science must dovetail with learning about science; this handbook is uniquely positioned as a locus for the discussion. -/- The handbook features sections on pedagogical, theoretical, national, and biographical research, setting the literature of each tradition in its historical context. Each chapter engages in an assessment of the strengths and weakness of the research addressed, and suggests potentially fruitful avenues of future research. A key element of the handbook’s broader analytical framework is its identification and examination of unnoticed philosophical assumptions in science and mathematics research. It reminds readers at a crucial juncture that there has been a long and rich tradition of historical and philosophical engagements with science and mathematics teaching, and that lessons can be learnt from these engagements for the resolution of current theoretical, curricular and pedagogical questions that face teachers and administrators.

The term pseudoscience refers to a highly heterogeneous set of practices, beliefs, and claims sharing the property of appearing to be scientific when in fact they contradict either scientific findings or the methods by which science proceeds. Classic examples of pseudoscience include astrology, parapsychology, and ufology; more recent entries are the denial of a causal link between the HIV virus and AIDS or the claim that vaccines cause autism. To distinguish between science and pseudoscience is part of what the philosopher (...) Karl Popper referred to as the demarcation problem, a project that has been dismissed by another philosopher, Larry Laudan, but that keeps gathering much interest in philosophers, scientists, educators, and policymakers. This entry provides the basics of the debate about demarcation, as well as a brief discussion of why it is of vital importance not just intellectually but for society at large. (shrink)

In this essay, I will explain why Methodological Naturalism (MN) fails as a demarcating criteria for science. I will argue that MN is not precise enough to be useful for demarcation, unable to follow the evidence where it leads, not theologically neutral (despite its stated goals as such), and difficult to justify (and currently unjustified) as an ontological or epistemic principle.

Thesis (Ph. D.)--University of Hawaii at Manoa, 1991.

This paper presents a simple, neutral, unbiased framework for assessing scientific methodologies that serves as both a positive contribution to the literature and an implicit critique of Reber and Alcock’s recent paper in the American Psychologist (2019). This is followed by an explicit critique of some of their key claims.

I don’t get it. I just don’t get it. This book is supposed to be about the relation between insider physics and outsider physics. It isn’t. As I read Physics on the Fringe, I was increasingly disappointed and frustrated at the amount of space given to Jim Carter, not only his “fringe physics” but also his personal doings. Admittedly he seems quite an interesting person, fun to be with, admirably self-motivated, helpful to others, a good citizen—not unlike quite a lot (...) of other people. But his “circlon theory” isn’t an exemplar of fringe physics, it’s way-way-out pseudo-science. And Carter is not even typical of way-way-out crackpots: As Wertheim says, Carter atypically is a successful entrepreneur and has a sense of humor. So the book’s title misleads, and unfortunately the book’s substance also misleads about science and fringe science and pseudo-science in a number of ways. (shrink)

Some vociferous proponents of established science assert that it should always be believed when there are controversies over issues of public importance. That assertion rests on three assumptions, none of which are usually made explicit: 1) that only science is capable of arriving at truths about the natural world and that it actually does so; 2) that “science” is identical to the views propounded by the contemporary prevailing establishment of science, its mainstream institutions; and 3) that science can be distinguished (...) unequivocally, with certainty, from everything else. None of those presumptions has been demonstrated to be correct, and indeed there are excellent historical and logical reasons to regard all of them as wrong. Since these underlying assumptions cannot be proven, self-styled “skeptics” and other activists who seek hegemony for contemporaneous scientific consensuses engage in intellectual and rhetorical misdirection to give actual uncertainty the appearance of “practical” certainty. In doing so, activists fail to acknowledge the crucial distinction between a point of view that appropriately guides scholarly discourse or scientific research and views (expert opinions or assertions or conclusions) that “everyone” should accept and that offer appropriate guidance to public policies and actions.

Recent decades have seen a number of public disputes over scientific anomalies and unorthodoxies, typically framed as science versus pseudo-science. This Essay suggests historical and intellectual context for these controversies. The main point: There is no universally applicable, objective, impartial formula for distinguishing good science from bad science or real science from pseudo—the devil is always in the details. Anomalies and unorthodoxies are defined implicitly by the contemporary state of the art in mainstream science; “pseudo-science” is a pejorative aimed at (...) non-mainstream claims in defense of the authority of established, mainstream science. WWII was a game-changer: In its aftermath, science achieved unprecedented influence over public policies. As the stakes became high, “pseudo-science” seemed no longer a sufficiently powerful pejorative and was superseded by charges of “junk science” and “denialism.”. (shrink)

In his article the author begins by defining what is meant by ‘science’ and ‘scientism.’ Second, he discusses some of the cultural dangers of scientism.

Debates about evolution and creation inevitably raise philosophical issues about the nature of scientific knowledge. What is a theory? What is an explanation? How is science different from non- science? How should theories be evaluated? Does science achieve truth? The aim of this chapter is to give a concise and accessible introduction to the philosophy of science, focusing on questions relevant to understanding evolution by natural selection, creation, and intelligent design. For the questions just listed, I state what I think (...) is the best available answer and show how it applies to debates about evolution and creationism. I also indicate alternative answers that are preferred by other philosophers. I hope that the result will be useful for science educators and anyone else involved in controversies about evolution and creation. (shrink)

Karl Popper, en tant que rationaliste critique, a été un opposant à toutes les formes de scepticisme, de conventionnalisme et de relativisme scientifique. En 1935, il a écrit Logik der Forschung. Zur Erkenntnistheorie der modernen Naturwissenschaft, traduisant plus tard le livre en anglais et le publiant sous le titre The Logic of Scientific Discovery (1959), considéré comme un travail de pionnier dans son domaine. De nombreux arguments de ce livre sont dirigés contre les membres du « Cercle de Vienne », (...) tels que Moritz Schlick, Otto Neurath, Rudolph Carnap, Hans Reichenbach, Carl Hempel et Herbert Feigl. Popper est d'accord avec eux sur les aspects généraux de la méthodologie scientifique et sur leur méfiance à l'égard de la méthodologie philosophique traditionnelle, mais ses solutions ont été sensiblement différentes. Popper a largement contribué aux débats sur la méthodologie scientifique générale, la démarcation de la pseudo-science, la nature des probabilités et la méthodologie des sciences sociales.

In the case of Kitzmiller et al. v. Dover Area School District, et al., Judge Jones ruled that a pro-intelligent design disclaimer cannot be read to public school students. In his decision, he gave demarcation criteria for what counts as science, ruling that intelligent design fails these criteria.

The way to refute intelligent design is not by declaring it unscientific, but by showing (...) that the empirical evidence for design is not there. (shrink)
