In this paper, I argue against Peter van Inwagen’s claim (in “Free Will Remains a Mystery”), that agent-causal views of free will could do nothing to solve the problem of free will (specifically, the problem of chanciness). After explaining van Inwagen’s argument, I argue that he does not consider all possible manifestations of the agent-causal position. More importantly, I claim that, in any case, van Inwagen appears to have mischaracterized the problem in some crucial ways. Once we are clear on (...) the true nature of the problem of chanciness, agent-causal views do much to eradicate it. (shrink)

I. Introduction “We can and do see the truth about many things: ourselves, others, trees and animals, clouds and rivers—in the immediacy of experience.”1 Absent from Bas van Fraassen’s list of those things we see are paramecia and mitochondria. We do not see such things, van Fraassen has long maintained, because they are unobservable, that is, they are undetectable by means of the unaided senses.2 But notice that these two notions—what we can see in the “immediacy” of experience and what (...) is detectable by means of the unaided senses—are not the same. There is no incoherence in maintaining that the immediacy of experience is capable of disclosing to us truths concerning entities that are not detectable by the naked eye. And so, I claim, it does; science and technology provide us with the means to see things we have never seen before. Some of those things are van Fraassen’s unobservables. That suggestion is nothing new. Grover Maxwell long ago emphasized the continuity between seeing with and without instrumentation.3 Van Fraassen originally provided two responses to Maxwell’s arguments: some things that you can see with instruments you can also see without instruments (and those are the observables); and..

The anti-reductionist who wants to preserve the causal efficacy of mental phenomena faces several problems in regard to mental causation, i.e. mental events which cause other events, arising from her desire to accept the ontological primacy of the physical and at the same time save the special character of the mental. Psychology tries to persuade us of the former, appealing thereby to the results of experiments carried out in neurology; the latter is, however, deeply rooted in our everyday actions and (...) beliefs and despite the constant opposition of science still very much alive. Difficulties, however, arise from a combination of two claims that are widely accepted in philosophy of mind, namely, physical monism and mental realism, the acceptance of which leads us to the greatest problem of mental causation: the problem of causal exclusion. Since physical causes alone are always sufficient for physical effects mental properties are excluded from causal explanations of our behaviour, which makes them “epiphenomenal”. The article introduces Van Gulick’s solution to the exclusion problem which tries to prove that physical properties, in contrast to mental properties, do not have as much of a privileged status with respect to event causation as usually ascribed. Therefore, it makes no sense to say that physical properties are causally relevant whereas mental properties are not. This is followed by my objection to his argument for levelling mental and physical properties with respect to causation of events. I try to show that Van Gulick’s argument rests on a premise that no serious physicalist can accept. (shrink)

Van Heijenoort’s main contribution to history and philosophy of modern logic was his distinction between two basic views of logic, first, the absolutist, or universalist, view of the founding fathers, Frege, Peano, and Russell, which dominated the first, classical period of history of modern logic, and, second, the relativist, or model-theoretic, view, inherited from Boole, Schröder, and Löwenheim, which has dominated the second, contemporary period of that history. In my paper, I present the man Jean van Heijenoort (Sect. 1); then (...) I describe his way of arguing for the second view (Sect. 2); and finally I come down in favor of the first view (Sect. 3). There, I specify the version of universalism for which I am prepared to argue (Sect. 3, introduction). Choosing ZFC to play the part of universal, logical (in a nowadays forgotten sense) system, I show, through an example, how the usual model theory can be naturally given its proper place, from the universalist point of view, in the logical framework of ZFC; I outline another, not rival but complementary, semantics for admissible extensions of ZFC in the very same logical framework; I propose a way to get universalism out of the predicaments in which universalists themselves believed it to be (Sect. 3.1). Thus, if universalists of the classical period did not, in fact, construct these semantics, it was not that their universalism forbade them, in principle, to do so. The historical defeat of universalism was not technical in character. Neither was it philosophical. Indeed, it was hardly more than the victory of technicism over the very possibility of a philosophical dispute (Sect. 3.2). (shrink)

Van Heijenoort’s account of the historical development of modern logic was composed in 1974 and first published in 1992 with an introduction by his former student. What follows is a new edition with a revised and expanded introduction and additional notes.

The paper aims at drawing the main lines of a reflection about architectonic space, starting from the comparison between two hypothesis, as much as ever different: Theodor Lipps’ spatial aesthetics and Hans van der Laan’s elemental theory. The emphasis given by both authors to the intersection between directions and way, but also to the mutual subordination between thing and space, allows to rewrite the obituary of architecture as a spatial art, according to which the Modern Style has turned the spatiality (...) into its specular visibility, into the spaciousness, into the indefinite continuity of the Bigness.

Leitmotifs in the life of Jean van Heijenoort.

A colleague’s personal recollections of Jean van Heijenoort’s contributions to the editing of volumes I–III of Gödel’s Collected Works and of his interactions with the other editors.

http://dx.doi.org/10.5007/1808-1711.2008v12n1p49 The aim of this article is to offer a rejoinder to an argument against scientific realism put forward by van Fraassen, based on theoretical considerations regarding microphysics. At a certain stage of his general attack to scientific realism, van Fraassen argues, in contrast to what realists typically hold, that empirical regularities should sometimes be regarded as “brute facts”, which do not ask for explanation in terms of deeper, unobservable mechanisms. The argument from microphysics formulated by van Fraassen is based (...) on the claim that in microphysics the demand for explanation leads to a demand for the so-called hidden-variable theories, which “runs contrary to at least one major school of thought in twentieth-century physics”. It is shown here that this argument does not represent an insurmountable obstacle to scientific realism, not even when a series of important theoretical and experimental results against hidden-variable theories — and not merely a conflict with a certain school of thought—is taken into account.

http://dx.doi.org/10.5007/1808-1711.2008v12n2p121 O objetivo deste trabalho é discutir e desenvolver o diagnóstico que efetua van Fraassen (1987, p. 110) da lei de Hardy-Weinberg, de acordo coo qual esta: 1) não pode ser considerada uma lei a ser utilizada como un axioma da teoria genética de populações, pois é uma lei de equilíbrio que só vale sob certas condições especiais, 2) só determina uma subclasse de modelos, 3) sua generalização resulta vácua e 4) variantes complexas da lei podem ser deduzidas para pressupostos (...) mais realistas. A discussão e desenvolvimento deste diagnóstico será levada a cabo tomando como base noções propostas por outra das concepções semânticas afim daquela desenvolvida por van Fraassen, a saber: a concepção estruturalista das teorias, e uma reconstrução da genética clássica de populações no marco de uma tal metateoria, também apresentada neste trabalho.

De acordo com a concepção dominante de causação, eventos espácio-temporalmente localizáveis que podem ser designados por termos singulares e descrições definidas são os únicos relata genuínos da relação causal. Isto dá apoio e é apoiado pela dicotomia aceita entre a explicação causal, concebida como uma relação intensional entre fatos ou verdades, e a relação natural e extensional da causação. O ensaio questiona este modo de ver e argumenta pela legitimidade da noção de causação por fatos: os relata de muitas relações (...) expressas pelo conector sentencial ‘(O fato) C causa (o fato) E’ podem ser causas e efeitos genuínos (I). Esta visão expandida da causação é então aplicada ao problema da causação mental. Assumindo a verdade do realizacionismo físico, o ensaio explora a conexão entre eficácia causal e relevância contrafactual de propriedades. Mostra-se que, pelo menos em muitos casos, as ligações contrafactuais corretas, requeridas pela causação, podem ser encontradas somente no nível dos fatos realizados, não no nível mais básico dos fatos realizadores (II). Finalmente, dadas as similaridades entre a defesa do fisicismo não-reducionista esboçada aqui e as tentativas menos modestas de justificação científica das pretensões do materialismo metafísico, justamente criticadas por van Fraassen como manifestações da ‘falsa consciência’, considera-se se e como a argumento principal do ensaio pode evitar o juízo crítico de van Fraassen (III).

It is argued that, contrary to prevailing opinion, Bas van Fraassen nowhere uses the argument from underdetermination in his argument for constructive empiricism. It is explained that van Fraassen’s use of the notion of empirical equivalence in The Scientific Image has been widely misunderstood. A reconstruction of the main arguments for constructive empiricism is offered, showing how the passages that have been taken to be part of an appeal to the argument from underdetermination should actually be interpreted.

Over the last twenty years, Bas van Fraassen has developed a “new epistemology”: an attempt to sail between Bayesianism and traditional epistemology. He calls his own alternative “voluntarism”. A constant pillar of his thought is the thought that rationality involves permission rather than obligation. The present paper aims to offer an appraisal of van Fraassen’s conception of rationality. In section 2, I review the Bayesian structural conception of rationality and argue that it has been found wanting. In sections 3 and (...) 4, I analyse van Fraassen’s voluntarism. I raise some objections about van Fraassen’s reliance on prior opinion and argue that the content of a belief matters to its rationality. In section 5, I criticise van Fraassen’s view that inference to the best explanation is incoherent. Finally, in section 6, I take on van Fraassen’s conception of rationality and show that it is too thin to fully capture rational judgement. (shrink)

Projet En développant son « empirisme constructif », Bas Van Fraassen est devenu une référence incontournable pour la philosophie des sciences contemporaine. Après la vague de critiques qui, vers les années 1960, avait fait perdre à l'empirisme logique sa prédominance dans le champ des idées, le réalisme scientifique semblait s'être imposé comme le seul compte rendu acceptable du travail et des orientations de la recherche. Quine avait beau énoncer ce que pourrait être un empirisme affranchi de ses deux « dogmes (...) » (l'intangibilité de la distinction vérités analytiques / vérités synthétiques, et la réduction des constructions aux « faits »), le programme d'une philosophie des sciences empiriste renouvelée restait à l'état d'esquisse. Mais par trois ouvrages successifs, Scientific Image (1980), Laws and symmetry (1989), et Quantum mechanics an empiricist view (1991), Van Fraassen a posé les bases d'un empirisme viable, parce que capable de prendre en charge la plupart des spécificités dont se prévaut le réalisme contre l'empirisme classique ou logique, et de rendre raison des développements les plus actuels de la physique. Contre l'empirisme classique ou logique, les réalistes font d'abord valoir que la réduction de toute réalité et de tout acte de référence aux phénomènes, ne rend justice ni à la pratique du langage courant ni à celle des sciences. Lorsque quelqu'un procède à une dénomination, il ne cherche pas à désigner par là une tranche d'apparaître, ou quelque ensemble fini et répertorié d'apparitions; il pointe vers "quelque chose" dont les modalités de manifestation sans fin assignable sont pour partie anticipées et pour partie ouvertes. De même, quand un chercheur scientifique parle de l'objet de ses investigations, il ne limite pas son discours à un ensemble fini de résultats d'expérience obtenus sous des conditions instrumentales actuellement disponibles; il renvoie à une entité dont la variété des manifestations futures est prévue aussi complètement que possible (et avec un succès croissant) par des cadres conceptuels et théoriques révisables. Face à cette objection, Van Fraassen fait jouer un rôle capital aux modèles dans sa version de l'empirisme.. (shrink)

Considering Pragma-Dialectics honors the monumental contributions of one of the foremost international figures in current argumentation scholarship: Frans van Eemeren. The volume presents the research efforts of his colleagues and addresses how their work relates to the pragma-dialectical theory of argumentation with which van Eemeren’s name is so intimately connected. This tribute serves to highlight the varied approaches to the study of argumentation and is destined to inspire researchers to advance scholarship in the field far into the (...) future. Replete with contributions from highly-esteemed academics in argumentation study, chapters in this volume address such topics as: *Pragma-dialectic versus epistemic theories of arguing and arguments; *Pragma-dialectics and self-advocacy in physician-patient interactions; *The pragma-dialectical analysis of the ad hominem family; *Rhetoric, dialectic, and the functions of argument; and *The semantics of reasonableness. As an exceptional volume and a fitting tribute, this work will be of interest to all argumentation scholars considering the astute insights and scholarly legacy of Frans van Eemeren. (shrink)

Analysis shows that statements of ability are disguised conditionals. More exactly, the correct analysis of 'X could have done A' is 'If X h decided (chosen, willed ...) to do A, X would have done A'. Therefore having acted freely--having been able to act otherwise than one fact did--is compatible with determinism (with the causal determination of one's acts).

The essays in this book challenge prevailing views on the way in which apocalyptic concerns contributed to larger processes of social change at the first millennium. Several basic questions unify the essays: What chronological and theological assumptions underlay apocalyptic and millennial speculations around the Year 1000? How broadly disseminated were those speculations? Can we speak of a mentality of apocalyptic hopes and anxieties on the eve of the millennium? If so, how did authorities respond to or even contribute to the (...) formation of this mentality? What were the social ramifications of apocalyptic hopes and anxieties, and of any efforts to suppress or redirect the more radical impulses that bred them? How did contemporaries conceptualize and then historicize the passing of the millennial date of 1000? Including the work of British, French, German, Dutch, and American scholars, this book will be the definitive resource on this fascinating topic, and should at the same time provoke new interest in and debate on the nature and causes of social change in early medieval Europe.

In this paper, the author defends Peter van Inwagen’s modal skepticism. Van Inwagen accepts that we have much basic, everyday modal knowledge, but denies that we have the capacity to justify philosophically interesting modal claims that are far removed from this basic knowledge. The author also defends the argument by means of which van Inwagen supports his modal skepticism, offering a rebuttal to an objection along the lines of that proposed by Geirrson. Van Inwagen argues that Stephen Yablo’s recent and (...) influential account of the relationship between conceivability and possibility supports his skeptical claims. The author’s defence involves a creative interpretation and development of Yablo’s account, which results in a recursive account of modal epistemology, what the author calls the “safe explanation” theory of modal epistemology.

Constructive empiricism is supposed to offer a positive alternative to scientific realism that dispenses with the need for metaphysics. I first review the terms of the debate before arguing that the standard objections to constructive empiricism are not decisive. I then explain van Fraassen's views on modality and counterfactuals, and argue that, because constructive empiricism recommends on epistemological grounds belief in the empirical adequacy rather than the truth of theories, it requires that there be an objective modal distinction between the (...) observable and the unobservable. This conclusion is incompatible with van Fraassen's empiricism. Finally I explain some further problems for constructive empiricism that arise when we consider modal matters. (shrink)

Hilary Putnam and Bas C. van Fraassen have been two pivotal figures in the scientific realism debate in the second half of the twentieth century. Their initial perspectives were antithetical—defining an archetypical scientific realist position (Putnam) and a major empiricism-inspired alternative to scientific realism (van Fraassen). But as the years (and the philosophical debates) went on, there have been important lines of convergence in the stances of these two thinkers, mostly motivated by an increasing flirting with pragmatism and by a (...) growing disdain towards metaphysics. Putnam’s views went through two major turns, in a philosophical journey he aptly described as taking him “from realism back to realism” (1994, 494). Being an arch scientific realist in the 1960s and the early 1970s, he moved to a trenchant critique of metaphysical realism and the adoption of a verificationist-‘internalist’ approach (what he called pragmatic or internal realism), which he upheld roughly until the end of the twentieth century. Then he adopted a direct realist outlook, what he called “common sense” or “natural realism”, which was based on the denial of at least some of the tenets of his internalist period (e.g., the abandonment of a verificationist conception of truth), while at the same time tried to avoid “the phantasies of metaphysical realism”. It is (almost) impossible to cover all aspects of Putnam’s realist endeavours. I will therefore focus on his changing views about scientific realism. Van Fraassen occupied a space in the scientific realism debate that was left vacant by Putnam’s critique of fictionalism and verificationism, viz., an agnostic stance towards the ontological commitments of literally understood scientific theories. His positive alternative to realism, Constructive Empiricism (CE), was meant to be a position suitable for post-positivist empiricists, that is philosophers who a) take for granted the empiricist dictum that all (substantive) knowledge stems from experience; b) take science seriously (but not uncritically) as the paradigm of rational inquiry; and c) take to heart all criticism of the positivist approach to science, bound as it was to issues concerning the language of theories and the privileging of an alleged theory-neutral observational vocabulary..

Bas van Fraassen claims that constructive empiricism strikes a balance between the empiricist's commitments to epistemic modesty -- that one's opinion should extend no further beyond the deliverances of experience than is necessary -- and to the rationality of science. In "Should the Empiricist be a Constructive Empiricist?" I argued that if the constructive empiricist follows through on her commitment to epistemic modesty she will find herself adopting a much more extreme position than van Fraassen suggests. Van Fraassen and Bradley (...) Monton have recently responded. My purpose here is to contest their response. The goal is not merely the rebuttal of a rebuttal; there is a lesson to learn concerning the realist/anti-realist dialectic generated by van Fraassen's view. (shrink)

In this three-part paper, my concern is to expound and defend a conception of science, close to Einstein's, which I call aim-oriented empiricism. I argue that aim-oriented empiricsim has the following virtues. (i) It solve the problem of induction; (ii) it provides decisive reasons for rejecting van Fraassen's brilliantly defended but intuitively implausible constructive empiricism; (iii) it solves the problem of verisimilitude, the problem of explicating what it can mean to speak of scientific progress given that science advances from one (...) false theory to another; (iv) it enables us to hold that appropriate scientific theories, even though false, can nevertheless legitimately be interpreted realistically, as providing us with genuine , even if only approximate, knowledge of unobservable physical entities; (v) it provies science with a rational, even though fallible and non-mechanical, method for the discovery of fundamental new theories in physics. In the third part of the paper I show that Einstein made essential use of aim-oriented empiricism in scientific practice in developing special and general relativity. I conclude by considering to what extent Einstein came explicitly to advocate aim-oriented empiricism in his later years. (shrink)

This paper criticizes the dominant approaches to presupposition projection and proposes an alternative. Both the update semantics of Heim and the discourse representation theory of van der Sandt have problems in explicating the presuppositions of disjunctions. Moreover, Heim's approach is committed to a conception of accommodation that founders on the problem of informative presuppositions, and van der Sandt's approach is committed to a conception of accommodation that generates over-interpretations of utterances. The present approach borrows Karttunen's idea that instead of associating (...) presuppositions with sentences, we should define the conditions that contexts must meet in order to satisfy-the-presuppositions-of a sentence. However, in place of Karttunen's conception of contexts in terms of common ground, the present theory substitutes a conception of contexts as objective entities that are independent of the attitudes of the interlocutors. Contexts, so conceived, may be defined as containing sets of relevant possibilities. This allows us to define the conditions under which a context satisfies-the-presuppositions-of a disjunction.

Peter van Inwagen's brand of materialism leads him to speculate that God actually removes the deceased at the moment of death and replaces the corpse with a simulacrum that decays or is cremated. Dean Zimmerman offers an account of resurrection that is loyal to Peter van Inwagen's commitment to a materialist metaphysics, with its stress on the earlier life processes of an organism immanently causing its later ones, while maintaining that resurrection is possible without involving God in any ‘body snatching’. (...) My contention is that Zimmerman's account is metaphysically impossible. His alleged ‘solution’ is at odds with the principles governing the ways in which an organism can assimilate new parts. Instead of providing a scenario where we can be resurrected, Zimmerman has merely sketched a scenario where we are duplicated. An alternative materialist account of resurrection is offered, one in which immanent causation is not necessary. (shrink)

We often speak of an object being composed of various other objects. We say that the deck is composed of the cards, that a road is the sum total of its sections, that a house is composed of its walls, ceilings, floors, doors, etc. Suppose we have some material objects. Here is a philosophical question: what conditions must obtain for those objects to compose something? In his recent book Material Beings, Peter van Inwagen addresses this question, which he calls the (...) ‘special composition question’; his answer is:1 (1) For any material objects X , the X s compose something iff the activity of the X s constitutes a life, or there is only one of the Xs. Additionally, he accepts a simpler thesis that follows from (1):2 (2) Every material object is either a mereological atom or a living thing, where a mereological atom is an object lacking proper parts. (2) may seem radical. If it is true then there are no tables, chairs, planets, protons, galaxies, gas stations, etc. But van Inwagen does not hold it lightly— there are serious difficulties with alternate views. Moreover, he claims that.. (shrink)

Replies to Ram Neta, James Van Cleve, and Crispin Wright for a book symposium on Reflective Knowledge (OUP, 2009).

In a recent article, van Fraassen has taken issue with the use to which Perrin’s experiments on Brownian motion have been put by philosophers, especially those defending scientific realism. He defends an alternative position by analysing the details of Perrin’s case in its historical context. In this reply, I argue that van Fraassen has not done the job well enough and I extend and in some respects attempt to correct his claims by close attention to the historical details.

This essay revisits Meyer Schapiro’s critique of Heidegger’s interpretation of Van Gogh’s painting of a pair of shoes in order to raise the question of the dispute between art history and philosophy as a contest increasingly ceded to the claim of the expert and the hegemony of the museum as culture and as cult or coded signifier.

, I argued that Bas van Fraassen's constructive empiricism was undermined in various ways by his antirealism about modality. Here I offer some comments and responses to the reply to my arguments by Bradley Monton and van Fraassen [2003].

In Belief and the Will, van Fraassen employed a diachronic Dutch Book argument to support a counterintuitive principle called Reflection. There and subsequently van Fraassen has put forth Reflection as a linchpin for his views in epistemology and the philosophy of science, and for the voluntarism (first-person reports of subjective probability are undertakings of commitments) that he espouses as an alternative to descriptivism (first-person reports of subjective probability are merely self-descriptions). Christensen and others have attacked Reflection, taking it to have (...) unpalatable consequences. We prescind from the question of the cogency of diachronic Dutch Book arguments, and focus on Reflection's proper interpretation. We argue that Reflection is not as counterintuitive as it appears — that once interpreted properly the status of the counterexamples given by Christensen and others is left open. We show also that descriptivism can make sense of Reflection, while voluntarism is not especially well suited to do so. (shrink)

What is not often noted about Bas van Fraassen’s distinctive approach to the scientific realism issue is that constructive empiricism, as he defines it, seems to involve a distinctively realist stance in regard to large parts of natural science. This apparent defection from the ranks of his more uncompromisingly anti‐realist colleagues raises many questions. Is he really leaning to realism here? If he is, why is this not more widely noted? And, more important, if he is, is he entitled to (...) this shyly realist concession? Does his many‐pronged attack on what he sees as the main arguments in support of realism leave him with the wherewithal? (shrink)
