We study the one-seller/two-buyer bargaining problem with negative identity-dependent externalities with an alternating offer bargaining model in which new owners of the object have the opportunity of resale. We identify the generically unique subgame perfect equilibrium outcome. The resale opportunity increases the competition among the buyers and therefore benefits the seller. When competition between buyers is very fierce, the seller may prefer to respond to bids rather than to propose an offer herself: a first-mover disadvantage.

All too often in contemporary discourse, we hear about science overstepping its proper limits—about its brazenness, arrogance, and intellectual imperialism. The problem, critics say, is scientism: the privileging of science over all other ways of knowing. Science, they warn, cannot do or explain everything, no matter what some enthusiasts believe. In Science Unlimited?, noted philosophers of science Maarten Boudry and Massimo Pigliucci gather a diverse group of scientists, science communicators, and philosophers of science to explore the limits of science (...) and this alleged threat of scientism. In this wide-ranging collection, contributors ask whether the term scientism in fact (or in belief) captures an interesting and important intellectual stance, and whether it is something that should alarm us. Is scientism a well-developed position about the superiority of science over all other modes of human inquiry? Or is it more a form of excessive confidence, an uncritical attitude of glowing admiration? What, if any, are its dangers? Are fears that science will marginalize the humanities and eradicate the human subject—that it will explain away emotion, free will, consciousness, and the mystery of existence—justified? Does science need to be reined in before it drives out all other disciplines and ways of knowing? Both rigorous and balanced, Science Unlimited? interrogates our use of a term that is now all but ubiquitous in a wide variety of contexts and debates. Bringing together scientists and philosophers, both friends and foes of scientism, it is a conversation long overdue. (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. But given that the pages of history are full of such plots, why are CTs regarded with suspicion? Just like with the traditional demarcation problem, philosophers disagree about where to draw the line between legitimate hypotheses about conspiracies and unfounded ‘conspiracy theories’. Some believe that there is no such demarcation line to be drawn, that each CT (...) should be evaluated on its own merits, and that the bad reputation of CTs is wholly undeserved. In this paper, I intend to rescue the intuition that there is indeed something prima facie suspicious about CTs. First, I demarcate legitimate theorizing about real-life conspiracies from “mere conspiracy theories”. Along the way, my analysis will clarify some epistemological issues surrounding falsifiability, asymmetries between causes and effects, and hypotheses involving intentional agents. Because of their extreme resilience to external criticism and counterevidence, I argue, CTs are the epistemological equivalent of a ‘black hole’, in which unwary truth-seekers are drawn, never to escape again. But this strong attraction of CTs comes at a steep price: their theoretical parameters are essentially arbitrary, making them vulnerable to internal disruption. In essence, because it is so easy to construct a novel CT, it is equally easy to construct many ones about the same historical event. And that is what justifies our suspicion of CTs. (shrink)

In the space of all possible beliefs, conspiracy theories stand out with a special and possibly unique feature: they are the only beliefs that predict an absence of evidence in their favor, and even the discovery of counterevidence. In the traditional, narrow sense of the term, a ‘conspiracy theory’ refers to an alternative explanation of a historical event in terms of a small group of actors working together to achieve some nefarious goal. In a broader sense, however, any theory that (...) involves a form of invisible intentional agency can adopt the contours of a conspiracy theory. In this paper, I adopt a broader and more abstract definition of conspiracy theories, based on a conceptual core that unifies all such theories. By drawing comparisons between conspiracy theories in a range of different domains, we gain more insight into their central epistemological defects, as well as their cultural dynamics. Some belief systems are inherently conspiratorial, in that they posit some form of intelligent agency that deliberately wants to escape detection, while others merely resort to conspiratorial reasoning when threatened with counterevidence. This paper builds on earlier research into the cultural evolution of belief systems. (shrink)

Starting with a discussion of what I call `Koyré's paradox of conceptual novelty', I introduce the ideas of Damerow et al. on the establishment of classical mechanics in Galileo's work. I then argue that although their view on the nature of Galileo's conceptual innovation is convincing, it misses an essential element: Galileo's use of the experiments described in the first day of the Two New Sciences. I describe these experiments and analyze their function. Central to my analysis is the idea (...) that Galileo's pendulum experiments serve to secure the reference of his theoretical models in actually occurring cases of free fall. In this way, Galileo's experiments constitute an essential part of the meaning of the new concepts of classical mechanics. (shrink)

Conceived by Johan van Benthem and Yde Venema, arrow logic started as an attempt to give a general account of the logic of transitions. The generality of the approach provided a wide application area ranging from philosophy to computer science. The book gives a comprehensive survey of logical research within and around arrow logic. Since the natural operations on transitions include composition, inverse and identity, their logic, arrow logic can be studied from two different perspectives, and by two (complementary) methodologies: (...) modal logic and the algebra of relations. Some of the results in this volume can be interpreted as price tags. They show what the prices of desirable properties, such as decidability, (finite) axiomatisability, Craig interpolation property, Beth definability etc. are in terms of semantic properties of the logic. The research program of arrow logic has considerably broadened in the last couple of years and recently also covers the enterprise to explore the border between decidable and undecidable versions of other applied logics. The content of this volume reflects this broadening. The editors included a number of papers which are in the spirit of this generalised research program. (shrink)

Philosophers of science have given up on the quest for a silver bullet to put an end to all pseudoscience, as such a neat formal criterion to separate good science from its contenders has proven elusive. In the literature on critical thinking and in some philosophical quarters, however, this search for silver bullets lives on in the taxonomies of fallacies. The attractive idea is to have a handy list of abstract definitions or argumentation schemes, on the basis of which one (...) can identify bad or invalid types of reasoning, abstracting away from the specific content and dialectical context. Such shortcuts for debunking arguments are tempting, but alas, the promise is hardly if ever fulfilled. Different strands of research on the pragmatics of argumentation, probabilistic reasoning and ecological rationality have shown that almost every known type of fallacy is a close neighbor to sound inferences or acceptable moves in a debate. Nonetheless, the kernel idea of a fallacy as an erroneous type of argument is still retained by most authors. We outline a destructive dilemma we refer to as the Fallacy Fork: on the one hand, if fallacies are construed as demonstrably invalid form of reasoning, then they have very limited applicability in real life. On the other hand, if our definitions of fallacies are sophisticated enough to capture real-life complexities, they can no longer be held up as an effective tool for discriminating good and bad forms of reasoning. As we bring our schematic “fallacies” in touch with reality, we seem to lose grip on normative questions. Even approaches that do not rely on argumentation schemes to identify fallacies fail to escape the Fallacy Fork, and run up against their own version of it. (shrink)

Na meer dan tien jaar komt Maarten Doorman met een nieuwe bundeling van essays. Ze lijken te gaan over van alles en nog wat: van een bedrieglijk stuk steen van de maan tot een dramatische scène in bad, van een romantische boswandeling tot Nipplegate, van Goethe tot David Bowie, van de woede van Schopenhauer tot de karper van Apollinaire en van tekenfilm tot Rijksmuseum. Maar steeds gaat het om het overbruggen van een afstand. Die tussen kunst en maatschappij, filosofie (...) en wereld, verleden en toekomst en afkeer en bewondering. 'Dichtbij en ver weg' is een verzameling goed geschreven opstellen waarin wat ver weg is dichtbij komt, een hartstochtelijk pleidooi voor geschiedenis en kunst. (shrink)

The scientific study of living organisms is permeated by machine and design metaphors. Genes are thought of as the ‘‘blueprint’’ of an organism, organisms are ‘‘reverse engineered’’ to discover their functionality, and living cells are compared to biochemical factories, complete with assembly lines, transport systems, messenger circuits, etc. Although the notion of design is indispensable to think about adaptations, and engineering analogies have considerable heuristic value (e.g., optimality assumptions), we argue they are limited in several important respects. In particular, the (...) analogy with human-made machines falters when we move down to the level of molecular biology and genetics. Living organisms are far more messy and less transparent than human-made machines. Notoriously, evolution is an opportunistic tinkerer, blindly stumbling on ‘‘designs’’ that no sensible engineer would come up with. Despite impressive technological innovation, the prospect of artificially designing new life forms from scratch has proven more difficult than the superficial analogy with ‘‘programming’’ the right ‘‘software’’ would suggest. The idea of applying straightforward engineering approaches to living systems and their genomes— isolating functional components, designing new parts from scratch, recombining and assembling them into novel life forms—pushes the analogy with human artifacts beyond its limits. In the absence of a one-to-one correspondence between genotype and phenotype, there is no straightforward way to implement novel biological functions and design new life forms. Both the developmental complexity of gene expression and the multifarious interactions of genes and environments are serious obstacles for ‘‘engineering’’ a particular phenotype. The problem of reverse-engineering a desired phenotype to its genetic ‘‘instructions’’ is probably intractable for any but the most simple phenotypes. Recent developments in the field of bio-engineering and synthetic biology reflect these limitations. Instead of genetically engineering a desired trait from scratch, as the machine/engineering metaphor promises, researchers are making greater strides by co-opting natural selection to ‘‘search’’ for a suitable genotype, or by borrowing and recombining genetic material from extant life forms.

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 this challenging essay, Maarten Doorman argues that in art, belief in progress is still relevant, if not essential. The radical freedoms of postmodernism, he claims, have had a crippling effect on art, leaving it in danger of becoming meaningless. Art can only acquire meaning through context the concept of progress, then, is ideal as the primary criterion for establishing that context. The history of art, in fact, can be seen as a process of constant accumulation, works of art (...) commenting on one another and enriching one another's meanings. It is these complex interrelationships and the progress they create in both art and its observers that Doorman, in a display of great philosophical erudition, defends. (shrink)

The German philosophical culture of the Middle Ages is inextricable linked to the thought of Albert the Great. This volume brings together 14 papers, which deal with Albert's influence from the points of view of mysticism, philosophy, and the history of universities.

The ‘European Space of Higher Education’ could be mapped as an infrastructure for entrepreneurship and a place where the distinction between the social and the economic becomes obsolete. Using Foucault's understanding of biopolitics and discussing the analyses of Agamben and Negri/Hardt it is argued that the actual governmental configuration, i.e. the economisation of the social, also has a biopolitical dimension. Focusing on the intersection between a politicisation and economisation of human life allows us to discuss a kind of ‘bio‐economisation’ , (...) a regime of economic terror and learning as investment. Finally it is argued how fostering learning, i.e. fostering life could turn into ‘let die’ and even into ‘make die’. (shrink)

Undergraduate geoscience students are rarely exposed to history and philosophy of science. I will describe the experiences with a short course unfavourably placed in the first year of a bachelor of earth science. Arguments how HPS could enrich their education in many ways are sketched. One useful didactic approach is to develop a broader interest by connecting HPS themes to practical cases throughout the curriculum, and develop learning activities that allow students to reflect on their skills, methods and their field (...) in relation to other disciplines and interactions with society with abilities gained through exposure to HPS. Given support of the teaching staff, the tenets of philosophy of science in practice, of conceptual history of knowledge, and of ethics of science for society can fruitfully and directly be connected to the existing curriculum. This is ideally followed by a capstone HPS course late in the bachelor programme. (shrink)

Philosophers and psychologists often assume that mirror reflections are optical illusions. According to many authors, what we see in a mirror appears to be behind it. I discuss two strategies to resist this piece of dogma. As I will show, the conviction that mirror reflections are illusions is rooted in a confused conception of the relations between location, direction, and visibility. This conception is unacceptable to those who take seriously the way in which mirrors contribute to our experience of the (...) world. My argument may be read as an advertisement of the neglected field of philosophical catoptrics, the philosophical study of the optical properties of mirrors. It enables us to recast familiar issues in the philosophy of perception. (shrink)

What makes beliefs thrive? In this paper, we model the dissemination of bona fide science versus pseudoscience, making use of Dan Sperber's epidemiological model of representations. Drawing on cognitive research on the roots of irrational beliefs and the institutional arrangement of science, we explain the dissemination of beliefs in terms of their salience to human cognition and their ability to adapt to specific cultural ecologies. By contrasting the cultural development of science and pseudoscience along a number of dimensions, we gain (...) a better understanding of their underlying epistemic differences. Pseudoscience can achieve widespread acceptance by tapping into evolved cognitive mechanisms, thus sacrificing intellectual integrity for intuitive appeal. Science, by contrast, defies those deeply held intuitions precisely because it is institutionally arranged to track objective patterns in the world, and the world does not care much about our intuitions. In light of these differences, we discuss the degree of openness or resilience to conceptual change (evidence and reason), and the divergent ways in which science and pseudoscience can achieve cultural “success”.

Part of the distinction between artefacts, objects made by humans for particular purposes, and natural objects is that artefacts are subject to normative judgements. A drill, say, can be a good drill or a poor drill, it can function well or correctly or it can malfunction. In this paper I investigate how such judgements fit into the domain of the normative in general and what the grounds for their normativity are. Taking as a starting point a general characterization of normativity (...) proposed by Dancy, I argue how statements such as ‘this is a good drill’ or ‘this drill is malfunctioning’ can be seen to express normative facts, or the content of normative statements. What they say is that a user who has a desire to achieve a particular relevant outcome has a reason to use, or not to use, the artefact in question. Next this analysis is extended to show that not just statements that say that an artefact performs its function well or poorly, but all statements that ascribe a function to an artefact can be seen as expressing a normative fact. On this approach the normativity of artefacts is analyzed in terms of reasons on grounds of practical, and to a lesser extent theoretical, rationality. I close by investigating briefly to what extent reasons on moral grounds are, in the analysis adopted here, involved in the normativity of artefacts.Keywords: Artefact; Normativity; Instrumental reason; Practical rationality; Function; Use.

The present paper presents a philosophical analysis of earth science, a discipline that has received relatively little attention from philosophers of science. We focus on the question of whether earth science can be reduced to allegedly more fundamental sciences, such as chemistry or physics. In order to answer this question, we investigate the aims and methods of earth science, the laws and theories used by earth scientists, and the nature of earth-scientific explanation. Our analysis leads to the tentative conclusion that (...) there are emergent phenomena in earth science but that these may be reducible to physics. However, earth science does not have irreducible laws, and the theories of earth science are typically hypotheses about unobservable (past) events or generalised - but not universally valid - descriptions of contingent processes. Unlike more fundamental sciences, earth science is characterised by explanatory pluralism: earth scientists employ various forms of narrative explanations in combination with causal explanations. The main reason is that earth-scientific explanations are typically hampered by local underdetermination by the data to such an extent that complete causal explanations are impossible in practice, if not in principle.

One way to address such questions about artifact kinds is to look for clues in the available literature on parallel questions that have been posed with respect to kinds in the natural domain. Philosophers have long been concerned with the ...

Relationalism maintains that perceptual experience involves, as part of its nature, a distinctive kind of conscious perceptual relation between a subject of experience and an object of experience. Together with the claim that perceptual experience is presentational, relationalism is widely believed to be a core aspect of the naive realist outlook on perception. This is a mistake. I argue that naive realism about perception can be upheld without a commitment to relationalism.

Is replication in the cultural domain ubiquitous, rare, or non-existent? And how does this relate to that paradigmatic case of replication, the copying of DNA in living cells? Theorists of cultural evolution are divided on these issues. The most important objection to the replication model has been leveled by Dan Sperber and his colleagues. Cultural transmission, they argue, is almost always reconstructive and transformative, while ‘replication’ can be seen as a rare limiting case at most. Though Sperber’s critique is valuable, (...) I argue that a purely informational and pragmatic approach to replication can clear up some confusion. By means of some thought experiments, I make a distinction between evocation and extraction of cultural information, and apply these concepts at different levels of abstraction. I conclude that, depending on our theoretical focus and our granularity of analysis, sometimes we can talk about replication in the cultural domain, even after having taken Sperber’s important points on board.

The concept of the future is re-emerging as an urgent topic on the academic agenda. In this article, we focus on the ‘politics of the future’: the social processes and practices that allow particular imagined futures to become socially performative. Acknowledging that the performativity of such imagined futures is well-understood, we argue that how particular visions come about and why they become performative is underexplained. Drawing on constructivist sociological theory, this article aims to fill this gap by exploring the question (...) ‘how do imagined futures become socially performative’? In doing so, the article has three aims to identify the leading social–theoretical work on the future; conceptualize the relationship of the imagination of the future with social practices and the performance of reality; provide a theoretical framework explaining how images of the future become performative, using the concepts ‘techniques of futuring’ and ‘dramaturgical regime’.

This paper presents an overview of the elements which characterize a research attitude and approach introduced by Michel Foucault and further developed as ‘studies of governmentality’ into a sub‐discipline of the humanities during the past decade, including also applications in the field of education. The paper recalls Foucault's introduction of the notion of ‘governmentality’ and its relation to the ‘mapping of the present’ and sketches briefly the way in which the studies of governmentality have been elaborated in general and in (...) the context of research in education more particularly. It indicates how the studies of governmentality can be related to a cartography of the learning society, a cartography which helps us to get lost and to liberate our view. (shrink)

True beliefs are better guides to the world than false ones. This is the common-sense assumption that undergirds theorizing in evolutionary epistemology. According to Alvin Plantinga, however, evolution by natural selection does not care about truth: it cares only about fitness. If our cognitive faculties are the products of blind evolution, we have no reason to trust them, anytime or anywhere. Evolutionary naturalism, consequently, is a self-defeating position. Following up on earlier objections, we uncover three additional flaws in Plantinga's latest (...) formulation of his argument: a failure to appreciate adaptive path dependency, an incoherent conception of content ascription, and a conflation of common-sense and scientific beliefs, which we diagnose as the ‘foundationalist fallacy’. More fundamentally, Plantinga's reductive formalism with respect to the issue of cognitive reliability is inadequate to deal with relevant empirical details. (shrink)

Eighteenth century river hydraulics used both theory and measurement to address problems of flood safety, navigation and defense related to the rivers. In the late eighteenth century the Dutch overseer of the rivers, Christiaan Brunings, integrated hydraulic theory and meteorological practices, which enabled him to design a unique instrument for measuring river flow. The question is whether the unprecedented detail of measurements fits the putative empirical stance in the eighteenth century. The interactions between theory, instrument, measurement, and other knowledge practices (...) are here assessed using experiences in similar measurement practices. I argue that Brunings had theoretical and embodied understanding of hydrodynamics, as he knew how to design an instrument for flow measurement of sufficient accuracy for his purpose in the sociopolitical context of river management.

Are there any such things as mind viruses? By analogy with biological parasites, such cultural items are supposed to subvert or harm the interests of their host. Most popularly, this notion has been associated with Richard Dawkins’ concept of the “selfish meme”. To unpack this claim, we first clear some conceptual ground around the notions of cultural adaptation and units of culture. We then formulate Millikan’s challenge: how can cultural items develop novel purposes of their own, cross-cutting or subverting human (...) purposes? If this central challenge is not met, talk of cultural ‘parasites’ or ‘selfish memes’ will be vacuous or superfluous. First, we discuss why other attempts to answer Millikan’s challenge have failed. In particular, we put to rest the claims of panmemetics, a somewhat sinister worldview according to which human culture is nothing more than a swarm of selfish agents, plotting and scheming behind the scenes. Next, we reject a more reasonable, but still overly permissive approach to mind parasites, which equates them with biologically maladaptive culture. Finally, we present our own answer to Millikan’s challenge: certain systems of misbelief can be fruitfully treated as selfish agents developing novel purposes of their own. In fact, we venture that this is the only way to properly understand them. Systems of misbelief are designed to spread in a viral-like manner, without any regard to the interests of their human hosts, and with possibly harmful consequences. As a proof of concept, we discuss witchcraft beliefs in early modern Europe. In this particular case, treating cultural representations as “parasites” – i.e. adopting the meme’s eye view – promises to shed new light on a mystery that historians and social scientists have been wrestling with for decades.

This article re-introduces the notion of liturgical mysticism from both the perspectives of systematic theology and Church history. The authors adopt an interdisciplinary approach grounded in theology aiming to revisit the concept of liturgical mysticism in order to contribute to developing an adequate interpretive model for mystical texts. The article introduces the notion of liturgical mysticism firstly by a systematic-theological fundamental analysis of Christian mystical experience, showing the uniqueness of that experience and the possible interconnections with liturgy; secondly, by studying (...) liturgical mysticism historically, in the context of the Middle Dutch tradition in the sixteenth century, especially the Arnhem Mystical Sermons, in order to provide a solid historical basis for our argumentation; lastly, the article explores first the impact of our findings on the theological understanding and method in the study of mysticism, and second it notes some ramifications for contemporary Christian spirituality. The authors attempt to show that liturgical mysticism, understood and practised as a tradition bound and context sensitive religious experience, is historically plausible and theologically promising.
