In lieu of an abstract, here is a brief excerpt of the content:Room for Maneuver When Raising Critical DoubtJan Albert Van Laar1When interlocutors start talking at cross-purposes it becomes less likely that they will be able to resolve their initial difference of opinion (Van Eemeren and Grootendorst 1992, 125). How much room should we give a party for rephrasing or revising her adversary’s standpoint in a manner that suits her individual purposes in the dialogue? Certainly, as textbooks in argumentation and (...) critical thinking make clear, we should steer clear of erecting and attacking straw men (Ennis 1996, 172; Govier 1985, 109–12; Groarke, Tindale, and Fisher 1997, 123). Still, a critic in a discussion or debate should be given some room to maneuver in order to rephrase the arguer’s position in her own words or to get at the underlying position of the arguer. In this article, I will be dealing with this issue from the pragma-dialectical perspective of strategic maneuvering between the shared dialectical objective of resolving a difference of opinion and the individual rhetorical objective of persuading the other side. According to existing accounts of the straw man fallacy (Talisse and Aikin 2006; Van Eemeren and Grootendorst 1992; Walton 1996), the criterion for fallaciousness resides in whether or not the critic misrepresents or distorts the arguer’s actual position. In this article I intend to provide more detailed guidelines for critics: a critic distorts or [End Page 195] misrepresents a position when she changes the formulation or nature of the arguer’s standpoint, even though this contribution by her cannot be reconstructed as containing a proposal for a change that might be acceptable to the arguer.In section 2 I will elaborate on the notion of confrontational maneuvering, that is, of strategic maneuvering between the dialectical and rhetorical goals that arise from the confrontation stage of a critical discussion. In section 3 I will characterize the form of maneuvering where an antagonist reformulates or modifies the protagonist’s standpoint in an opportune way. In section 4 I will examine the conditions under which applications of maneuvering of this kind can be sound and legitimate from a dialectical perspective and relate these conditions to the straw man fallacy. In section 5 the results of the preceding sections will be applied to a case.2. Confrontational ManeuveringIn argumentative discourse, participants typically try to achieve two kinds of objectives. First, they try to be dialectically reasonable, and second, they are out for some kind of personal triumph. The act, by the critic, of reformulating or revising the arguer’s standpoint will be dealt with from this dual perspective of strategic maneuvering (Van Eemeren and Houtlosser 2000, 2003). In order to analyze and evaluate the maneuver under discussion, I will elaborate in this section, first, on the notion of critical discussion in order to clarify the meaning of dialectical reasonableness and fallaciousness; second, on the importance of reconstruction for understanding argumentative discourse; third, on the notion of a confrontation stage; and fourth, on the distinction between direct and indirect maneuvering. These notions will be applied as follows: critics have some room for maneuvering when raising critical doubt, even when they change the arguer’s position or formulation, because there are contexts of utterance within confrontations where such a contribution does allow for a reconstruction in such a way that the result is not a direct and fallacious confrontational maneuver but, rather, an indirect and dialectically reasonable one.According to the pragma-dialectical methodology developed by Van Eemeren and Grootendorst (1984, 1992, 2004), an argumentative discourse must be reconstructed and evaluated from the perspective of a critical discussion. A critical discussion is a normative procedure that starts from a difference of opinion and that is solely aimed at resolving this dispute on the merits of the case (as perceived by the participants). When following [End Page 196] this procedure, discussants start by putting their difference of opinion into words in the confrontation stage; they proceed by deciding on the procedural and material starting points in the opening stage and by exchanging arguments and criticisms in the argumentation stage; and then they bring their discussion to a close by deciding in the concluding stage on whether the initial...

Genesis: The Evolution of Biology presents a history of the past two centuries of biology, suitable for use in courses, but of interest more broadly to evolutionary biologists, geneticists, and biomedical scientists, as well as general readers interested in the history of science. The book covers the early evolutionary biologists-Lamarck, Cuvier, Darwin and Wallace through Mayr and the neodarwinian synthesis, in much the same way as other histories of evolution have done, bringing in also the social implications, the struggles with (...) our religious understanding, and the interweaving of genetics into evolutionary theory. What is novel about Sapp's account is a real integration of the cytological tradition, from Schwann, Boveri, and the other early cell biologists and embryologists, and the coverage of symbiosis, microbial evolutionary phylogenies, and the new understanding of the diversification of life coming from comparative analyses of complete microbial genomes. The book is a history of theories about evolution, genes and organisms from Lamarck and Darwin to the present day. This is the first book on the general history of evolutionary biology to include the history of research and theories about symbiosis in evolution, and first to include research on microbial evolution which were excluded from the classical neo-Darwinian synthesis. Bacterial evolution, and symbiosis in evolution are also excluded from virtually every book on the history of biology. (shrink)

Hypothetico-deductive (H-D) confirmation builds on the idea that confirming evidence consists of successful predictions that deductively follow from the hypothesis under test. This article reviews scope, history and recent development of the venerable H-D account: First, we motivate the approach and clarify its relationship to Bayesian confirmation theory. Second, we explain and discuss the tacking paradoxes which exploit the fact that H-D confirmation gives no account of evidential relevance. Third, we review several recent proposals that aim at a sounder and (...) more comprehensive formulation of H-D confirmation. Finally, we conclude that the reputation of hypothetico-deductive confirmation as outdated and hopeless is undeserved: not only can the technical problems be addressed satisfactorily, the hypothetico-deductive method is also highly relevant for scientific practice.

This book provides for the first time a complete history of the doctrine of the transcendentals and shows its importance for the understanding of philosophy in the Middle Ages.

On the standard interpretation, if a person holds cyclical preferences, the person is prone to acting irrationally. I provide a different interpretation, tying cyclical preferences not to irrationality, but to indecision. According to this alternative understanding – coined the indecision interpretation – top cycles in a person’s preferences can be associated with a difficulty in justifying one’s choice. If an agent’s justificatory impasse persists despite attempts to resolve the cycle, the agent can be deemed undecided. The indecision interpretation is compatible (...) with the standard interpretation of such cycles as instances of irrationality. Yet indecision corresponds to a first-person, non-instrumental perspective on the problem, whereas irrationality usually corresponds to a third-person, instrumental perspective. Due to these differences, interpreting cycles in terms of indecision offers a novel conceptual perspective, pertinent both for explanatory purposes and for the aim of normative theorizing. (shrink)

Some critical reactions hardly give clues to the arguer as to how to respond to them convincingly. Other critical reactions convey some or even all of the considerations that make the critic critical of the arguer’s position and direct the arguer to defuse or to at least contend with them. First, an explication of the notion of a critical reaction will be provided, zooming in on the degree of “directiveness” that a critical reaction displays. Second, it will be examined whether (...) there are normative requirements that enhance the directiveness of criticism. Does the opponent have in circumstances a dialectical obligation to provide clarifications, explanations, or even arguments? In this paper, it is hypothesized that the competitiveness inherent in critical discussion must be mitigated by making the opponent responsible for providing her counterconsiderations, if available, thus assisting the proponent in developing an argumentative strategy that defuses them.

The interpretation of tests of a point null hypothesis against an unspecified alternative is a classical and yet unresolved issue in statistical methodology. This paper approaches the problem from the perspective of Lindley's Paradox: the divergence of Bayesian and frequentist inference in hypothesis tests with large sample size. I contend that the standard approaches in both frameworks fail to resolve the paradox. As an alternative, I suggest the Bayesian Reference Criterion: it targets the predictive performance of the null hypothesis in (...) future experiments; it provides a proper decision-theoretic model for testing a point null hypothesis and it convincingly accounts for Lindley's Paradox.

A platitude questioned by many Buddhist thinkers in India and Tibet is the existence of the world. We might be tempted to insert some modifier here, such as “substantial,” “self-existent,” or “intrinsically existent,” for, one might argue, these thinkers did not want to question the existence of the world tout court but only that of a substantial, self-existent, or otherwise suitably qualified world. But perhaps these modifiers are not as important as is generally thought, for the understanding of the world (...) questioned is very much the understanding of the world everybody has. It is the understanding that there is a world out there —independent of our minds — and that when we speak and think about this world we mostly get it right. But the Madhyamaka thinkers under discussion here deny that there is a world out there and claim that our opinions about it are to the greatest part fundamentally and dangerously wrong. (shrink)

The subject of this article is Modal-Epistemic Arithmetic (MEA), a theory introduced by Horsten to interpret Epistemic Arithmetic (EA), which in turn was introduced by Shapiro to interpret Heyting Arithmetic. I will show how to interpret MEA in EA such that one can prove that the interpretation of EA is MEA is faithful. Moreover, I will show that one can get rid of a particular Platonist assumption. Then I will discuss models for MEA in light of the problems of logical (...) omniscience and logical competence. Awareness models, impossible worlds models and syntactical models have been introduced to deal with the first problem. Certain conditions on the accessibility relations are needed to deal with the second problem. I go on to argue that those models are subject to the problem of quantifying in, for which I will provide a solution. (shrink)

How should we construe the unity, in affective experience, of felt bodily changes on the one hand and intentionality on the other, without forcing affective phenomena into a one-sided theoretical framework such as cognitivism? To answer this question, I will consider the specific kind of self-awareness implicit in affectivity. In particular, I will explore the idea that a bodily sense of ability is crucial for affective self-awareness. Describing the affective ways of “grasping oneself” manifest in a person’s felt sense of (...) ability will help us understand the intimate connection between bodily feelings and intentionality in affective processes. In order to illustrate these experiential structures in a concrete case, I will discuss experiential changes often reported by sufferers of depression. (shrink)

In this paper, I explore links between the phenomenology-inspired philosophy of emotion, especially discussions of affective intentionality and situated affectivity, and those strands of work in the field of cultural affect studies that take their inspiration fromSpinoza and Deleuze. As bridges between these fields, I propose the concepts ‘disclosive posture’ and ‘affective arrangement’. ‘Disclosive posture’ condenses insights from phenomenological work on affectivity, especially those pertaining to what Heidegger calls Befindlichkeit. ‘Affective arrangement’ is a descendant of Deleuze and Guattari’s term agencement. (...) It refers to heterogeneous ensembles of elements coalescing into a sphere of heightened affective intensity in a local setting. I develop this notion into a tool for analyzing situated affectivity. As it does not yet figure prominently within debates in the philosophy of emotion, I will outline what is meant by ‘affective arrangement’ in some detail. Throughout, I discuss a productive tension between these two conceptual strands. (shrink)

The aim of this paper is to mount a philosophical challenge to the currently highly visible research and discourse on empathy. The notion of empathetic perspective-shifting—a conceptually demanding, high-level construal of empathy in humans that arguably captures the core meaning of the term—is criticized from the standpoint of a philosophy of normatively accountable agency. Empathy in this demanding sense fails to achieve a true understanding of the other and instead risks to impose the empathizer’s self-constitutive agency upon the person empathized (...) with. Attempts to ‘simulate’ human agency, or attempts to emulate its cognitive or emotional basis, will likely distort their target phenomena in profound ways. Thus, agency turns out to be empathy’s blind spot. Elements of an alternative understanding of interpersonal relatedness are also discussed, focusing on aspects of ‘interaction theory’. These might do some of the work that high-level constructs of empathy had been supposed to do without running into similar conceptual difficulties. (shrink)

This essay proposes to view networks as sociocultural structures. Following authors from Leopold von Wiese and Norbert Elias to Gary Alan Fine and Harrison White, networks are configurations of social relationships interwoven with meaning. Social relationships as the basic building blocks of networks are conceived of as dynamic structures of reciprocal (but not necessarily symmetric) expectations between alter and ego. Through their transactions, alter and ego construct an idiosyncratic "relationship culture" comprising symbols, narratives, and relational identities. The coupling of social (...) relationships to networks, too, is heavily laden with meaning. The symbolic construction of persons is one instance of this coupling. Another instance is the application of social categories (like race or gender), which both map and structure social networks. The conclusion offers an agenda for research on this "meaning structure of social networks.". (shrink)

Belief in the afterlife is still very much alive in Western civilisation, even though the truth of its existence is no longer universally accepted. Surprisingly, however, heaven, hell and the immortal soul were all ideas which arrived relatively late in the ancient world. Originally Greece and Israel - the cultures that gave us Christianity - had only the vaguest ideas of an afterlife. So where did these concepts come from and why did they develop? In this fascinating, learned, but highly (...) readable book, Jan N. Bremmer - one of the foremost authorities on ancient religion - takes a fresh look at the major developments in the Western imagination of the afterlife, from the ancient Greeks to the modern near-death experience.

This dissertation is on infinite regress arguments in philosophy. Its main goals are to explain what such arguments from many distinct philosophical debates have in common, and to provide guidelines for using and evaluating them. Two theories are reviewed: the Paradox Theory and the Failure Theory. According to the Paradox Theory, infinite regress arguments can be used to refute an existentially or universally quantified statement (e.g. to refute the statement that at least one discussion is settled, or the statement that (...) discussions are settled only if there is an agreed-upon criterion to settle them). According to the Failure Theory, infinite regress arguments can be used to demonstrate that a certain solution fails to solve an existentially or universally quantified problem (e.g. to demonstrate that a certain solution fails to settle all discussions, or that it fails to settle even one discussion). In the literature, the Paradox Theory is fairly well-developed, and this dissertation provides the Failure Theory with the same tools. (shrink)

The effects of public announcements, private communications, deceptive messages to groups, and so on, can all be captured by a general mechanism of updating multi-agent models with update action models, now in widespread use. There is a natural extension of the definition of a bisimulation to action models. Surely enough, updating with bisimilar action models gives the same result (modulo bisimulation). But the converse turns out to be false: update models may have the same update effects without being bisimilar. We (...) propose action emulation as a notion of equivalence more appropriate for action models, and generalizing standard bisimulation. It is proved that action emulation provides a full characterization of update effect. We first concentrate on the general case, and next focus on the important case of action models with propositional preconditions. Our notion of action emulation yields a simplification procedure for action models, and it gives designers of multi-agent systems a useful tool for comparing different ways of representing a particular communicative action.

We live in a world in which scientific expertise and its epistemic authority become more important. On the other hand, the financial interests in research, which could potentially corrupt science, are increasing. Due to these two tendencies, a concern for the integrity of scientific research becomes increasingly vital. This concern is, however, hollow if we do not have a clear account of research integrity. Therefore, it is important that we explicate this concept. Following Rudolf Carnap’s characterization of the task of (...) explication, this means that we should develop a concept that is similar to our common sense notion of research integrity, exact, fruitful, and as simple as possible. Since existing concepts do not meet these four requirements, we develop a new concept in this article. We describe a concept of epistemic integrity that is based on the property of deceptiveness, and argue that this concept does meet Carnap’s four requirements of explication. To illustrate and support our claims we use several examples from scientific practice, mainly from biomedical research. (shrink)

Precaution is a relevant and much-invoked value in environmental risk analysis, as witnessed by the ongoing vivid discussion about the precautionary principle (PP). This article argues (i) against purely decision-theoretic explications of PP; (ii) that the construction, evaluation, and use of scientific models falls under the scope of PP; and (iii) that epistemic and decision-theoretic robustness are essential for precautionary policy making. These claims are elaborated and defended by means of case studies from climate science and conservation biology.

Respecting Persons in Theory and Practice is a collection of essays of the moral and political philosophy of Jan Narveson. The essays in this collection share a consistent theme running through much of Narveson's moral and political philosophy, namely that politics and morals stem from the interests of individual people, and have no antecedent authority over us. The essays in this collection, in various ways and as applied to various aspects of the scene, argue that the ultimate and true point (...) of politics and morals is to enable us to make our lives better, according to our varied senses of what that might mean.

The neurosciences not only challenge assumptions about the mind’s place in the natural world but also urge us to reconsider its role in the normative world. Based on mind-brain dualism, the law affords only one-sided protection: it systematically protects bodies and brains, but only fragmentarily minds and mental states. The fundamental question, in what ways people may legitimately change mental states of others, is largely unexplored in legal thinking. With novel technologies to both intervene into minds and detect mental activity, (...) the law should, we suggest, introduce stand alone protection for the inner sphere of persons. We shall address some metaphysical questions concerning physical and mental harm and demonstrate gaps in current doctrines, especially in regard to manipulative interferences with decision-making processes. We then outline some reasons for the law to recognize a human right to mental liberty and propose elements of a novel criminal offence proscribing severe interventions into other minds. (shrink)

In this paper I will argue that medical specialists interpret and diagnose through technological mediations like X-ray and fMRI images, and by actualizing embodied skills tacitly they are determining the identity of objects in the perceptual field. The initial phase of human interpretation of visual objects takes place during the moments of visual perception before we are consciously aware of the perceived. What facilitate this innate ability to interpret are experiences, learning and training that become humanly embodied skills. These embodied (...) skills are actualized during the moments of visual perception. My argument is that biology, society and instruments constitute unique individual ontologies influencing specialist readings of the technological output, in other words, putting limits on the ‘‘truth-to-nature’’ relation, which is so much sought for in science.

The essay takes the widespread complaint that societies today are deeply divided and polarized as a starting point. Affirming that there is no democracy without division, it asks what it means for conflict and disagreement to be dealt with in a respectful and civil manner. As an illustration of the main argument, the way that liberals (in the broadest sense) have engaged with populist leaders is criticized on both a strategic and normative level. An alternative to existing strategies of dealing (...) with the conflict between liberals and populist is then proposed. Finally, the article also asks under what conditions civil disobedience might be an appropriate response to authoritarian populism. (shrink)

This article analyses domestic and foreign reactions to a 2008 report in the British Medical Journal on the complementary and, as argued, synergistic relationship between palliative care and euthanasia in Belgium. The earliest initiators of palliative care in Belgium in the late 1970s held the view that access to proper palliative care was a precondition for euthanasia to be acceptable and that euthanasia and palliative care could, and should, develop together. Advocates of euthanasia including author Jan Bernheim, independent from but (...) together with British expatriates, were among the founders of what was probably the first palliative care service in Europe outside of the United Kingdom. In what has become known as the Belgian model of integral end-of-life care, euthanasia is an available option, also at the end of a palliative care pathway. This approach became the majority view among the wider Belgian public, palliative care workers, other health professionals, and legislators. The legal regulation of euthanasia in 2002 was preceded and followed by a considerable expansion of palliative care services. It is argued that this synergistic development was made possible by public confidence in the health care system and widespread progressive social attitudes that gave rise to a high level of community support for both palliative care and euthanasia. The Belgian model of so-called integral end-of-life care is continuing to evolve, with constant scrutiny of practice and improvements to procedures. It still exhibits several imperfections, for which some solutions are being developed. This article analyses this model by way of answers to a series of questions posed by Journal of Bioethical Inquiry consulting editor Michael Ashby to the Belgian authors. (shrink)

Are the political ideals of liberty and equality compatible? This question is of central and continuing importance in political philosophy, moral philosophy, and welfare economics. In this book, two distinguished philosophers take up the debate. Jan Narveson argues that a political ideal of negative liberty is incompatible with any substantive ideal of equality, while James P. Sterba argues that Narveson's own ideal of negative liberty is compatible, and in fact leads to the requirements of a substantive ideal of equality. Of (...) course, they cannot both be right. Thus, the details of their arguments about the political ideal of negative liberty and its requirements will determine which of them is right. Engagingly and accessibly written, their debate will be of value to all who are interested in the central issue of what are the practical requirements of a political ideal of liberty. (shrink)

This paper develops elements of a phenomenological account of how interpersonal care contributes to the structure of intentionality. It does so by reflecting on a first-person account of parental grief by the poet and thinker Denise Riley. Her autobiographical notes on the aftermath of the death of her adult son revolve around a marked experience of altered temporal flow. By relating what she considers to be an almost unspeakable alteration in her experience of time, Riley unearths a level of nuanced (...) phenomenological reflection that can inform philosophical studies of lived time and intentionality. The paper will build on Riley's observations on altered temporal experience in grief to explore the entanglement of temporality and intersubjectivity in the constitution of intentionality. By doing so, the paper demonstrates that and how a phenomenological study of grief can directly speak to key concerns of the philosophy of mind and of interdisciplinary consciousness studies.

This article conceptualizes power in the context of long-term process of structural change. First, it discusses the field of transition studies, which deals with processes of structural change in societal systems on the basis of certain presumptions about power relations, but still lacks an explicit conceptualization of power. Then the article discusses some prevailing points of contestation in debates on power. It is argued that for the context of transition studies, it is necessary to develop an interdisciplinary framework in which (...) power is explicitly conceptualized in relation to change. Subsequently, such a framework is presented, with reference to existing literature on power. Starting with a philosophical and operational definition of power, a typology is developed of the different ways in which power can be exercised, explicitly including innovative power and transformative power. Finally, the presented power framework is applied to transition studies, redefining pivotal transition concepts in terms of power and formulating hypotheses on the role of power in transitions. By doing so, the article not only offers an interdisciplinary framework to study power in the context of transition studies, but also contributes to power debates more generally by including innovation and transformation as acts of power, and thereby proposes a re-conceptualization of the relation between power and structural change.

In this essay, I argue, via a revision of Freud's notions of primary and secondary process, that experiences of resonant form lie at the root of many serious ineffability claims.

Amongst its many other merits this collection of essays demonstrates the growing maturity of the study of the Indian philosophical tradition. Much of the good scholarship done on non-Western, and in particular on Indian philosophy over the last decades has attempted to show that these texts hailing from east of Suez contain interesting and sophisticated discussions in their own right, discussions that have to be understood against the Ancient Indian intellectual and cultural context rather than evaluated by how closely they (...) can be seen as conforming to current fashions in the Western philosophical debate.

In this paper I criticize arguments by Pauline Phemister and Matthew Stuart that John Locke's position in his An Essay Concerning Human Understanding allows for natural kinds based on similarities among real essences. On my reading of Locke, not only are similarities among real essences irrelevant to species, but natural kind theories based on them are unintelligible.

Political theorists tend to dismiss the concept of constitutional patriotism for two main reasons. On the one hand, constitutional patriotism — understood as a post-national, universalist form of democratic political allegiance — is rejected on account of its abstract quality. On the otherhand, it is argued that constitutional patriotism, while apprearing universalist, is in fact particular through and through. According to this genealogical critique, it is held that constitutional patriotism might have been appropriate in the context when it originated — (...) namely West Germany, a half-nation with a deeply compromised sense of nationality on account of the Nazi past — but it is not universally applicable. This article reconstructs the origins of constitutional patriotism arguing that both the ‘protective’ and state-centred patriotism of Dolf Sternberger, and the ‘purifying’ patriotism of Jurgen Habermas — focused mainly on the public sphere — can indeed be understood as relying on ‘supplements of particularily’. However, there are also normative connections between universalist constitutional morality and militant democracy on the one hand, and universalist constitutionalist morality and an imperative to remember on the other. Thus, the genealogical critique by itself is insufficient to invalidate the idea of constitutional patriotism. (shrink)

Pyrrhonism is the view that we should suspend all our beliefs in order to be rational and reach peace of mind. One of the main objections against this view is that it makes action impossible. One cannot suspend all beliefs and act normally at once. Yet, the question is: What is it about actions that they require beliefs? This issue has hardly been clarified in the literature. This is a bad situation, for if the objection fails and it turns out (...) that the Pyrrhonists found a way to secure peace of mind, we better know the details. In the following, I take up this systematic query and show how the objection can be made precise. Despite Sextus Empiricus? ingenious appearance/reality distinction, which is to ensure Pyrrhonism in this, I eventually argue that a life by appearances is quite unlike a normal life. (shrink)

Embodied cognition is an interpretative—or hermeneutical—cognition inherent in motor-sensory perception intrinsically informed by biological and sociocultural memory, a cognition embedded in the organism as well as the socio-cultural environment interacting with it (Ward et al. TOPOI 36:365–375, 2017), of which technologies are a part. Yet, smart machines are advancing on human abilities to perceive and interpret concerning the accuracy, quantity, and quality of the data processed. Machines process and categorize images, perform classification tasks, they calculate and perform pattern analysis, all (...) machine learning processes are task-specific. Machine learning processes resemble human interpretative processes; however, these are two very different ways of “dealing with something,” although both can be said to be hermeneutical, one enactive, the other material; the first is a meaning-generating interpretative process, the second a statistics-based information output. The information extracted from all the data fed into the computer is the end-product of machine learning, whereas human interpretative enactments are continuous and necessary for any application of the information output.

A set of parameters for classifying composition operations is introduced. These parameters determine whether a composition operation is 1) universal, 2) determinate, 3) whether there is a difference between possible and actual compositions, 4) whether there can be singleton compositions, 5) whether they give rise to a hierarchy, and 6) whether components of compositions can be repeated. Philosophical implications of these parameters (in particular in relation to set theory) and mereology are discussed.

Proposition 28 from Proclus'Elements of Theologyis consistently cited as saying that every producing causefirstbrings about effects that are like it andtheneffects that are unlike it. This is a theorem to which Proclus is indeed committed, but I argue that it is not what Proclus is claiming here. At this stage of his general argument, he merely argues that every cause produces things that are like it, without saying anything about other products than the immediate ones. The standard interpretation of proposition (...) 28 is therefore wrong. This becomes clear if one pays close attention to the argumentative structure of theElements of Theologyand to the proof given for proposition 28. (shrink)

The aim of this article is to provide a historical response to Michel Janssen’s (2009) claim that the special theory of relativity establishes that relativistic phenomena are purely kinematical in nature, and that the relativistic study of such phenomena is completely independent of dynamical considerations regarding the systems displaying such behavior. This response will be formulated through a historical discussion of one of Janssen's cases, the experiments carried out by Walter Kaufmann on the velocity-dependence of the electron's mass. Through a (...) discussion of the different responses formulated by early adherents of the principle of relativity (Albert Einstein, Max Planck, Hermann Minkowski and Max von Laue) to these experiments, it will be argued that the historical development of the special theory of relativity argues against Janssen's historical presentation of the case, and that this raises questions about his general philosophical claim. It will be shown, more specifically, that Planck and Einstein developed a relativistic response to the Kaufmann experiments on the basis of their study of the dynamics of radiation phenomena, and that this response differed significantly from the response formulated by Minkowski and Laue. In this way, it will be argued that there were, at the time, two different approaches to the theory of relativity, which differed with respect to its relation to theory, experiment, and history: Einstein's and Planck's heuristic approach, and Minkowski's and Laue's normative approach. This indicates that it is difficult to say, historically speaking, that the special theory of relativity establishes the kinematical nature of particular phenomena. Instead, it will be argued that the theory of relativity should not be seen as a theory but rather as outlining an approach, and that the nature of particular scientific phenomena is something that is open to scientific debate and dispute.
