The plausibility of so-called ‘rational explanations’ in cognitive science is often contested on the grounds of computational intractability. Some have argued that intractability is a pseudoproblem, however, because cognizers do not actually perform the rational calculations posited by rational models; rather, they only behave as if they do. Whether or not the problem of intractability is dissolved by this gambit critically depends, inter alia, on the semantics of the ‘as if’ connective. First, this paper examines the five most sensible explications (...) in the literature, and concludes that none of them actually circumvents the problem. Hence, rational ‘as if’ explanations must obey the minimal computational constraint of tractability. Second, this paper describes how rational explanations could satisfy the tractability constraint. Our approach suggests a computationally unproblematic interpretation of ‘as if’ that is compatible with the original conception of rational analysis. (shrink)

Many cognitive scientists, having discovered that some computational-level characterization f of a cognitive capacity φ is intractable, invoke heuristics as algorithmic-level explanations of how cognizers compute f. We argue that such explanations are actually dysfunctional, and rebut five possible objections. We then propose computational-level theory revision as a principled and workable alternative.

Advancement in cognitive science depends, in part, on doing some occasional ‘theoretical housekeeping’. We highlight some conceptual confusions lurking in an important attempt at explaining the human capacity for rational or coherent thought: Thagard & Verbeurgt’s computational-level model of humans’ capacity for making reasonable and truth-conducive abductive inferences (1998; Thagard, 2000). Thagard & Verbeurgt’s model assumes that humans make such inferences by computing a coherence function (f_coh), which takes as input representation networks and their pair-wise constraints and gives as output (...) a partition into accepted (A) and rejected (R) elements that maximizes the weight of satisfied constraints. We argue that their proposal gives rise to at least three difficult problems. (shrink)

We present a criterion for the use of thought experiments as a guide to possibilia that bear on important arguments in philosophy of religion. We propose that the more successful thought experiments are closer to the world in terms of phenomenological realism and the values they are intended to track. This proposal is filled out by comparing thought experiments of life after death by Peter van Inwagen and Dean Zimmerman with an idealist thought experiment. In terms of realism and values (...) we contrast an exemplary thought experiment by Iris Murdoch with one we find problematic by William Irwin. (shrink)

Paraconsistent logics are logical systems that reject the classical principle, usually dubbed Explosion, that a contradiction implies everything. However, the received view about paraconsistency focuses only the inferential version of Explosion, which is concerned with formulae, thereby overlooking other possible accounts. In this paper, we propose to focus, additionally, on a meta-inferential version of Explosion, i.e. which is concerned with inferences or sequents. In doing so, we will offer a new characterization of paraconsistency by means of which a logic is (...) paraconsistent if it invalidates either the inferential or the meta-inferential notion of Explosion. We show the non-triviality of this criterion by discussing a number of logics. On the one hand, logics which validate and invalidate both versions of Explosion, such as classical logic and Asenjo–Priest’s 3-valued logic LP. On the other hand, logics which validate one version of Explosion but not the other, such as the substructural logics TS and ST, introduced by Malinowski and Cobreros, Egré, Ripley and van Rooij, which are obtained via Malinowski’s and Frankowski’s q- and p-matrices, respectively.

In some recent papers, Cobreros, Egré, Ripley and van Rooij have defended the idea that abandoning transitivity may lead to a solution to the trouble caused by semantic paradoxes. For that purpose, they develop the Strict-Tolerant approach, which leads them to entertain a non-transitive theory of truth, where the structural rule of Cut is not generally valid. However, that Cut fails in general in the target theory of truth does not mean that there are not certain safe instances of (...) Cut involving semantic notions. In this paper we intend to meet the challenge of answering how to regain all the safe instances of Cut, in the language of the theory, making essential use of a unary recovery operator. To fulfill this goal, we will work within the so-called Goodship Project, which suggests that in order to have non-trivial naïve theories it is sufficient to formulate the corresponding self-referential sentences with suitable biconditionals. Nevertheless, a secondary aim of this paper is to propose a novel way to carry this project out, showing that the biconditionals in question can be totally classical. In the context of this paper, these biconditionals will be essentially used in expressing the self-referential sentences and, thus, as a collateral result of our work we will prove that none of the recoveries expected of the target theory can be non-trivially achieved if self-reference is expressed through identities.

Two recent and influential papers, van Rooij 2007 and Lassiter 2012, propose solutions to the proviso problem that make central use of related notions of independence—qualitative in the first case, probabilistic in the second. We argue here that, if these solutions are to work, they must incorporate an implicit assumption about presupposition accommodation, namely that accommodation does not interfere with existing qualitative or probabilistic independencies. We show, however, that this assumption is implausible, as updating beliefs with conditional information does (...) not in general preserve independencies. We conclude that the approach taken by van Rooij and Lassiter does not succeed in resolving the proviso problem. (shrink)

Can the experience of great art play a role in our coming to understand the ethical framework of another person? In this article I draw out three themes from Iris Murdoch’s ‘The Sovereignty of Good’ in order to show the role that communal attention to works of art can play in our ethical lives. I situate this role in the context of Murdoch’s wider philosophical views.

Some artworks are called sublime because of their capacity to move human imagination in a different way than the experience of beauty. The following discussion explores how Van Gogh’s The Starry Night along with some of his other late landscape paintings accomplish this peculiar movement of imagination thus qualifying as sublime artworks. These artworks constitute examples of the higher aesthetic principles and must be judged according to the cosmological-aesthetic criteria for they manage to generate a transition between ethos and phusis (...) and present them in unity. Here, referring to Heraclitean, Kantian, Nietzschean and Heideggerian metaphysics and aesthetics, I propose that the principles of motion and transition be the new cosmologic-aesthetic categories for the judgment of sublime artworks as well as for the understanding of the world (Weltanschauung) they represent.

Three-dimensional material models of molecules were used throughout the 19th century, either functioning as a mere representation or opening new epistemic horizons. In this paper, two case studies are examined: the 1875 models of van ‘t Hoff and the 1890 models of Sachse. What is unique in these two case studies is that both models were not only folded, but were also conceptualized mathematically. When viewed in light of the chemical research of that period not only were both of these (...) aspects, considered in their singularity, exceptional, but also taken together may be thought of as a subversion of the way molecules were chemically investigated in the 19th century. Concentrating on this unique shared characteristic in the models of van ‘t Hoff and the models of Sachse, this paper deals with the shifts and displacements between their operational methods and existence: between their technical and epistemological aspects and the fact that they were folded, which was forgotten or simply ignored in the subsequent development of chemistry.

Art plays a significant role in Iris Murdoch’s moral philosophy, a major part of which may be interpreted as a proposal for the revision of religious belief. In this paper, I identify within Murdoch’s philosophical writings five distinct but related ways in which great art can assist moral/religious belief and practice: art can reveal to us “the world as we were never able so clearly to see it before”; this revelatory capacity provides us with evidence for the existence of (...) the Good, a metaphor for a transcendent reality of which God was also a symbol; art is a “hall of reflection” in which “everything under the sun can be examined and considered”; art provides us with an analogue for the way in which we should try to perceive our world; and art enables us to transcend our selfish concerns. I consider three possible objections: that Murdoch’s theory is not applicable to all forms of art; that the meaning of works of art is often ambiguous; and that there is disagreement about what constitutes a great work of art. I argue that none of these objections are decisive, and that all forms of art have at least the potential to furnish us with important tools for developing the insight required to live a moral/religious life.

Interview met Babs van den Bergh over haar studie filosofie en de daaropvolgende carrière.

Iris Marion Young’s politics of difference promotes equality among socially and culturally different groups within multicultural states and advocates group autonomy to empower such groups to develop their own voice. Extending the politics of difference to the international sphere, Young advocates “decentered diverse democratic federalism” that combines local self-determination and cosmopolitanism, while adamantly rejecting nationalism. Herr argues that nationalism, charitably interpreted, is not only consistent with Young’s politics of difference but also necessary for realizing Young’s ideal in the global (...) arena. (shrink)

Toon van Eijk: Spinoza in het licht van bewustzijnsontwikkeling De beroemde filosoof Spinoza is moeilijk te doorgronden. Emeritus hoogleraar Maarten van Buuren heeft in 2016 twee boeken over Spinoza gepubliceerd, waarin hij diens filosofie op nauwgezette en verhelderende manier analyseert. Volgens Van Buuren is de kern van Spinoza’s ethiek de bevrijding van bevoogding en het streven om in overeenstemming te leven met de wereld en met zichzelf. Een aantal sleutelbegrippen in Spinoza’s filosofie zijn de immanente, in de natuur-inwonende God, zelfbeschikking, (...) de rede, intuïtie, macht en zelftoe-eigening. In dit boek bespreekt Toon van Eijk deze sleutelbegrippen aan de hand van de analyse van Van Buuren en de filosofie van Maharishi Mahesh Yogi, de grondlegger van de Transcendente Meditatie (TM) techniek. Filosofische begrippen blijven echter tandeloos zonder mogelijkheden om deze ideeën te verwerkelijken. Een synthese van filosofisch redeneren en praktijken voor bewustzijnsontwikkeling is nodig. Hoewel Spinoza een ethiek zonder metafysica voorstond, is Van Eijk van mening dat daadwerkelijk wijs handelen moeilijk zonder enige metafysische bagage kan. (shrink)

The novel begins as follows:"Dora Greenfield left her husband because she was afraid of him. She decided six months later to return to him for the same reason. The absent Paul, haunting her with letters and telephone bells and imagined footsteps on the stairs had begun to be the greater torment. Dora suffered from guilt, and with guilt came fear. She decided at last that the persecution of his presence was to be preferred to the persecution of his absence."Murdoch's novel (...) The Bell is about Imber Court. It is a small Anglican religious community of lay people whose lives were transformed, not just by the arrival of a couple of dissimilar visitors, not just by the arrival of a new bell to be installed at Imber Abbey located beyond the lake, but more significantly by the discovery of a centuries-old bell the story of which is engulfed in a terrible legend.

Dombrowski and Murdoch offer versions of the ontological argument which aim to avoid two types of objection – those concerned with the nature of the divine, and those concerned with the move from an abstract concept to a mind-independent reality. For both, the nature of the concept of God/Good entails its instantiation, and both supply a supporting argument from experience. It is only Murdoch who successfully negotiates the transition from an abstract concept to the instantiation of that concept, however, and (...) this is achieved by means of an ontological argument from moral experience which, in a reversal of the Kantian doctrine, depends ultimately on a form of the cosmological argument.

A critical review essay, this work explains the methodological, material, and ideological reasons for why "diversity" initiatives in philosophy face an up-hill battle.

In this paper I introduce the transcendental argument for Christian theism in the context of Reformed theologian and philosopher Cornelius Van Til’s thought. I then present the critique proffered by Barry Stroud against ambitious transcendental arguments, and survey various formulations of transcendental arguments in the literature, seeking how the objection bears upon them. I argue that Adrian Bardon’s (2005) interpretation is the most helpful in understanding the Stroudian objection. From this interpretation, two types of possible rebuttals are deduced. Proceeding to (...) survey the responses offered by Van Tillians to this objection in the recent literature, I discern two general strategies pursued in these responses, which map onto the previously deduced types of rebuttals: the Biblical justification strategy and the objection-undermining strategy. I argue that all the specific attempts to answer Stroud which I examine here (those of Butler, Bosserman, and Fluhrer) are inadequate and that these two strategies, in general, face serious problems. I conclude with considering the options before the proponent of the transcendental argument for Christian theism and with offering a new objection to the argument, which focuses on its inconsistency with the implications of Christian theism itself.

Spinoza's political writings are not merely a theoretical exercise or a philosophical conclusion of his system. They are part of a very practical political discussion in seventeenth-century Holland. Spinoza was influenced by and played a role in a political movement known as "Radical Cartesianism", which combined ideas from Descartes and Hobbes in order to argue against the reinstatement of a stadholder. This movement provided arguments for religious and philosophical freedom and against monarchy based on a fundamental drive of self-preservation and (...) a particular understanding of the passions. This paper provides a general introduction to Radical Cartesianism by explaining its historical context and discussing two Radical Cartesian voices: Lambertus van Velthuysen and the brothers De la Court. The final section discusses Spinoza's political philosophy as a systemization of their Radical Cartesian ideas. (shrink)

According to Peter van Inwagen, C. S. Lewis failed in his attempt to undermine naturalism with his Argument from Reason. According to van Inwagen, Lewis provides no justification for his central premise, that naturalism is inconsistent with holding beliefs for reasons. What is worse, van Inwagen argues that the main premise in Lewis's argument from reason is false. We argue that it is not false. The defender of Lewis's argument can make use of the problem of mental causal drainage, a (...) longstanding issue in philosophy of mind, to show how van Inwagen's objection fails. (shrink)

In a recent article published in Ergo and entitled "Ontic explanation is either ontic or explanatory, but not both," Cory Wright and Dingmar van Eck have sought to undermine any ontic approach to explanation, providing three arguments to show that an epistemic approach is "the only game in town." I show that each of their arguments is straightforwardly question-begging. For brevity, I make my counter-arguments by showing how the claims of Sheredos (2016)-whom Wright & van Eck cite as an ally-undermine (...) each of their own arguments. The consumer update is: there is no new decisive argument against an ontic view, the epistemic view is not the only game in town, and reconciliation between the ontic and epistemic views remains possible. -/- .

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)

Milieufilosofisch Nederland wordt momenteel verdeeld door een controverse naar aanleiding vanrecente publicaties van de Wageningse filosofen Keulartz en Korthals. In dit artikel wil ik - aande hand van een analyse van het gebruik van het natuurbegrip bij Wim Zweers - laten zien dat Keulartz op een tot nu toe onderbelicht probleem wijst: het probleem van de veelheid vannatuurbeelden. Tegelijkertijd wil ik echter aantonen dat Keulartz' eigen, 'post-naturalistische' positie op een tegenspraak berust. Tenslotte geef ik aan hoe deze controverses zijn terug (...) tevoeren op een onvermijdelijke spanning in onze morele omgang met de natuur, en zoek ik naar een manier waarop deze spanning binnen de milieu-ethiek vruchtbaar kan worden gemaakt.

Bestaat de kernactiviteit van de meester erin om zijn eigen kennis uit te leggen en over te dragen? De Franse filosoof Jacques Rancière laat zien dat een gelegenheidsexperiment van Joseph Jacotot ons een ander voorbeeld aanreikt: de onwetende meester. In zijn boek De onwetende meester: vijf lessen over intellectuele emancipatie (Le maître ignorant: Cinq leçons sur l'émancipation intellectuelle) stelt hij dat de onwetende meester evengoed of zelfs beter in staat is leerlingen iets te leren dan de wetende meester. Rancière neemt (...) in feite twee onderwijspraktijken als voorbeeld: de traditionele praktijk van de wetende meester die uitleg geeft en kennis overdraagt en de experimentele praktijk van de onwetende meester die geen uitleg geeft maar vooral gericht is op de verificatie van aandacht. In dit artikel wil ik op basis van een korte analyse van deze twee praktijken laten zien hoe we uit Rancière’s boek een model kunnen afleiden voor het articuleren van de theoretische principes die impliciet in onderwijspraktijken werkzaam zijn. Dit model is gestoeld op het volgende uitgangspunt: door een succesvolle of juist problematische onderwijspraktijk als voorbeeld te nemen kunnen we de theoretische principes articuleren die erin werkzaam zijn. Dit schept de mogelijkheid om de focus van de van de praktijken naar de principes te verleggen. Hierdoor wordt de onderwijspraktijk op een nieuwe manier inzichtelijk en kunnen we haar theoretisch expliciteren. (shrink)

This is my reply to Josh Weisberg, Robert Van Gulick, and William Seager, published in JCS vol 20, 2013. This symposium grew out of an author-meets-critics session at the Central APA conference in 2013 on my 2012 book THE CONSCIOUSNESS PARADOX (MIT Press). Topics covered include higher-order thought (HOT) theory, my own "wide intrinsicality view," the problem of misrepresentation, targetless HOTs, conceptualism, introspection, and the transitivity principle.

Hogescholen zijn dienstbaar aan de samenleving, zo valt te lezen in de strategische onderwijsagenda van het hoger beroepsonderwijs. Maar wat houdt deze publieke functie precies in? Het gedachtegoed van politiek denker Hannah Arendt biedt docenten en beleidsmakers ten minste drie handelingsperspectieven. De auteur illustreert deze drie perspectieven met voorbeelden uit de onderwijspraktijk.

Van Ingen's aim aim is to vindicate the moral life by mounting and then meeting a powerful challenge. But he makes it so easy to be moral - it is enough to care about one other person - and so tough to be amoral - it involves being absolutely selfish - that his challenge is no challenge at all. It's not much of a vindication of morality if the morality you vindicate makes Tony Soprano a moral person.

Is de herhaling mogelijk? Deze ogenschijnlijk simpele vraag vormt het uitgangspunt van De herhaling. Een proeve van experimenterende psychologie door Constantin Constantius (1843), een van de meest curieuze geschriften uit het oeuvre van Søren Kierkegaard. In dit artikel worden twee aspecten aan de orde gesteld die De herhaling tot een nog altijd belangrijk boek maken: 1) De ongewone filosofische stijl die in dit boek ontwikkeld wordt en 2) De eigenzinnige opvatting over vrijheid en subjectiviteit die er onder de noemer 'de (...) herhaling' in naar voren wordt gebracht. Zoals de ondertitel 'een proeve van experimenterende psychologie' al aangeeft, is De herhaling geen klassieke filosofische verhandeling waarin op systematische wijze wordt uitgelegd wat er onder de herhaling - als filosofische begrip - verstaan moet worden. Integendeel, het is een uiterst experimenteel boek waarin een nieuwe filosofische stijl wordt geïntroduceerd. Er wordt zodoende nergens een eenduidige definitie gegeven van de herhaling in filosofische zin die ik in het vervolg zal aanduiden als de 'existentiële herhaling'. Sterker nog, de twee verschijningsvormen van de herhaling - de alledaagse en de existentiële herhaling - worden telkens welbewust met elkaar verward. Pas in de afsluitende brief aan de echte lezer van dit boek wordt duidelijk in welke richting we het verschil tussen deze twee vormen van herhaling moeten zoeken. (shrink)

Paul Valéry is de dichter die zwijgt; de denker die weigert filosoof te zijn; de schrijver die de taal in staat van beschuldiging stelt; de expert die volhoudt een amateur te zijn; de mysticus die zijn heil zoekt bij de wiskunde; de stamelaar die aan een kwaal van precisie lijdt; de Narcissus die misschien toch liever Orpheus had willen zijn. Hij is de chroniqueur van het denken en de meester van de tegenspraak. Ik probeer me hem voor te stellen. Het (...) is 1894 en hij zit gebogen te schrijven in de schriftjes waarin hij elk ochtend 'entre la lampe et le soleil' zijn denken fileert, een project dat uitmondde in ca. 30.000 bladzijden weerbarstige onvoltooidheid: de Cahiers.

Ruetsche (1996) has argued that van Fraassen's (1991) Copenhagen Variant of the Modal Interpretation (CVMI) gives unsatisfactory accounts of measurement and of state preparation. I defend the CVMI against Ruetsche's first argument by using decoherence to show that the CVMI does not need to account for the measurement scenario which Ruetsche poses. I then show, however, that there is a problem concerning preparation, and the problem is more serious than the one Ruetsche focuses on. The CVMI makes no substantive predictions (...) for the everyday processes we take to be measurements. (shrink)

Recensie van: Christoph Menke, Tmgodie im Sittlichen. Gerechtigkeit und Freiheit nach Hegel. Frankfurt: Suhrkamp, 1996. Paul Cobben, Postdialectische zedelijkheid. Ontwerp voor een Hegeliaans antwoord op Heidegger, Habermas, Derrida en Levinas. Kampen: Kok Agora, 1996. Hegels rechtsfilosofie speelt in de hedendaagse discussie tussen communitaristen en liberalen een belangrijke rol. Hij wordt door sommigen beschouwd als iemand die de vrijheid van het individu het primaat geeft - een echte liberaal dus -, dan wel als iemand die het individu ondergeschikt maakt aan de (...) gemeenschap, omdat indivi- dualiteit slechts binnen een gemeenschap kan ontstaan. Deze discussie vormt ook een deel van de achtergrond van Tragodie im Sittlichen en Postdialectische zedelijk- heid. Christoph Menke en Paul Cobben betogen beiden dat Hegel weliswaar te- kortgeschoten is in het doordenken van (aspecten van) de verhouding tussen indivi- du en gemeenschap, maar dat reeds in zijn eigen werk aanwijzingen te vinden zijn voor een correctie daarvan. Menke richt zich daarbij nadrukkelijker op de kant van het individu, Cobben meer op een herschrijving van de inrichting van de gemeen- schap. (shrink)

Do abstract paintings still make sense and if so what do they mean? By reducing the paintings to simple square blots as by Cézanne, to lines as by van Gogh and color traces as by Monet their meaning is fundamentally questioned. But by interpreting these compositions as effective forces or rather affective stimuli a new and different meaning becomes apparent. Landscapes are no longer introduced but made real in the aesthetic experience. Therefore aesthetics or rather aisthetics (perception) can be defined (...) as a notion of experience and knowledge. Thus the notion of an image gets a new understanding: it can be described as an "energetic system". (shrink)

In this article, I respond to critiques of my book Kant’s Radical Subjectivism: Perspectives on the Transcendental Deduction (London: Palgrave Macmillan, 2017). I address issues that are raised concerning objectivity, the nature of the object, the role of transcendental apperception and the imagination, and idealism. More in particular I respond to an objection against my reading of the necessary existence of things in themselves and their relation to appearances. I also briefly respond to a question that relates to the debate (...) on Kantian nonconceptualism, more in particular, the question whether Kant allows animals objective intentionality. Lastly, I respond to one objection against my reading of Hegel’s critique of Kant. (The copy uploaded here is an English translation of the original Dutch version that is published in the journal.).

Psychological approaches to treating mental illness or improving psychological wellbeing are invariably based on the explicit or implicit understanding that there is an intrinsically existing ‘self’ or ‘I’ entity. In other words, regardless of whether a cognitive-behavioural, psychodynamic, or humanistic psychotherapy treatment model is employed, these approaches are ultimately concerned with changing how the ‘I’ relates to its thoughts, feelings, and beliefs, and/or to its physical, social, and spiritual environment. Although each of these psychotherapeutic modalities have been shown to have (...) utility for improving psychological health, there are inevitably limitations to their effectiveness and there will always be those individuals for whom they are incompatible. Given such limitations, research continuously attempts to identify and empirically validate more effective, acceptable and/or diverse treatment approaches. One such approach gaining momentum is the use of techniques that derive from Buddhist contemplative practice. Although mindfulness is arguably the most popular and empirically researched example, there is also growing interest into the psychotherapeutic applications of Buddhism’s ‘non-self’ ontological standpoint (in which ontology is basically the philosophical study of the nature or essence of being, existence, or reality).

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.

As analytic philosophy is becoming increasingly aware of and interested in its own history, the study of that field is broadening to include, not just its earliest beginnings, but also the mid-twentieth century. One of the towering figures of this epoch is W.V. Quine (1908-2000), champion of naturalism in philosophy of science, pioneer of mathematical logic, trying to unite an austerely physicalist theory of the world with the truths of mathematics, psychology, and linguistics. Quine's posthumous papers, notes, and drafts revealing (...) the development of his views in the forties have recently begun to be published, as well as careful philosophical studies of, for instance, the evolution of his key doctrine that mathematical and logical truth are continuous with, not divorced from, the truths of natural science. But one central text has remained unexplored: Quine's Portuguese-language book on logic, his 'farewell for now' to the discipline as he embarked on an assignment in the Navy in WWII. Anglophone philosophers have neglected this book because they could not read it. Jointly with colleagues, I have completed the first full English translation of this book. In this accompanying paper I draw out the main philosophical contributions Quine made in the book, placing them in their historical context and relating them to Quine's overall philosophical development during the period. Besides significant developments in the evolution of Quine's views on meaning and analyticity, I argue, this book is also driven by Quine's indebtedness to Russell and Whitehead, Tarski, and Frege, and contains crucial developments in his thinking on philosophy of logic and ontology. This includes early versions of some arguments from 'On What There Is', four-dimensionalism, and virtual set theory. (shrink)

This is a review of Henk Woldring's book on Karl Mannheim.

An overview of 20 years of environmental philosophy in the Netherlands.

In this paper I argue that aim-oriented empiricism provides decisive grounds for accepting scientific realism and rejecting instrumentalism. But it goes further than this. Aim-oriented empiricism implies that physicalism is a central part of current (conjectural) scientific knowledge. Furthermore, we can and need, I argue, to interpret fundamental physical theories as attributing necessitating physical properties to fundamental physical entities.

This article paradoxically tries to come closer to an idea of justice with the help of the destructive — anything but nihilistic — criticism thereof by Hans Kelsen. It argues that his relativistic approach, in which this idea undergoes a metamorphosis to become a realisable value of a social order, brings us closer to an obvious and objective form of justice that is almost taken for granted. Just in our liberal and plural democracy this approach might prove to be of (...) more value than a transcendental theory that passes speculative judgements on the essence of absolute justice, about which we are unable to come to an agreement.

I talk about the relation between the direct encounters with values that I take to be a key part of ordinary moral phenomenology, and the well-worn topic of demandingness. I suggest that an ethical philosophy based on (inter alia) such encounters sheds interesting light on some familiar problems.
