A vernacular fifteenth-century sermon tells us, in order to warn of the threats to spiritual welfare posed by dance, that cyclic motion and centering of sensory impressions – amongst them intimate conversation – are essential elements of dance. When blending out the parenesis, implicit poetics of medieval dance can be distilled from that sermon. The way how these essential elements of dance are used for generating disruptions within literary plots will be demonstrated in three literary texts dating from the thirteenth (...) to the fifteenth century: Disruptions in connection with dance occur when contrary concepts of motion clash with each other, for example the linearity of the chivalrous way through the Other World with the cyclicity of round dances. ‚Der Württemberger‘, however, collides two contrary concepts of time which can be paraphrased as spatial metaphors, namely the linearity of earthly life which collides with the cyclicity of eternal damnation, a collision symbolized by the expulsion of life out of the dance of the death. Finally in ‚Ritter Sociabilis‘, dance generates a virtual space which subverts the courtly society. The protagonists of all these texts differently manage to resolve disruptions, namely by redemption, by repentance, or by continuing disruptions which they have caused themselves. (shrink)

Explainable artificial intelligence (XAI) aims to help people understand black box algorithms, particularly of their outputs. But what are these explanations and when is one explanation better than another? The manipulationist definition of explanation from the philosophy of science offers good answers to these questions, holding that an explanation consists of a generalization that shows what happens in counterfactual cases. Furthermore, when it comes to explanatory depth this account holds that a generalization that has more abstract variables, is broader in (...) scope and/or more accurate is better. By applying these definitions and contrasting them with alternative definitions in the XAI literature I hope to help clarify what a good explanation is for AI. (shrink)

According to Hempel’s influential theory of explanation, explaining why some a is G consists in showing that the truth that a is G follows from a law-like generalization to the effect that all Fs are G together with the initial condition that a is F. While Hempel’s overall account is now widely considered to be deeply flawed, the idea that some generalizations play the explanatory role that the account predicts is still often endorsed by contemporary philosophers of science. This idea, (...) however, conflicts with widely shared views in metaphysics according to which the generalization that all Fs are G is partially explained by the fact that a is G. I discuss two solutions to this conflict that have been proposed recently, argue that they are unsatisfactory, and offer an alternative. (shrink)

This paper discusses counterexamples to the thesis that the probabilities of conditionals are conditional probabilities. It is argued that the discrepancy is systematic and predictable, and that conditional probabilities are crucially involved in the apparently deviant interpretations. Furthermore, the examples suggest that such conditionals have a less prominent reading on which their probability is in fact the conditional probability, and that the two readings are related by a simple step of abductive inference. Central to the proposal is a distinction between (...) causal and purely stochastic dependence between variables. (shrink)

How ought you to evaluate your options if you're uncertain about what's fundamentally valuable? A prominent response is Expected Value Maximisation (EVM)—the view that under axiological uncertainty, an option is better than another if and only if it has the greater expected value across axiologies. But the expected value of an option depends on quantitative probability and value facts, and in particular on value comparisons across axiologies. We need to explain what it is for such facts to hold. Also, EVM (...) is by no means self-evident. We need an argument to defend that it’s true. This book introduces an axiomatic approach to answer these worries. It provides an explication of what EVM means by use of representation theorems: intertheoretic comparisons can be understood in terms of facts about which options are better than which, and mutatis mutandis for intratheoretic comparisons and axiological probabilities. And it provides a systematic argument to the effect that EVM is true: the theory can be vindicated through simple axioms. The result is a formally cogent and philosophically compelling extension of standard decision theory, and original take on the problem of axiological or normative uncertainty. (shrink)

Users of sociotechnical systems often have no way to independently verify whether the system output which they use to make decisions is correct; they are epistemically dependent on the system. We argue that this leads to problems when the system is wrong, namely to bad decisions and violations of the norm of practical reasoning. To prevent this from occurring we suggest the implementation of defeaters: information that a system is unreliable in a specific case (undercutting defeat) or independent information that (...) the output is wrong (rebutting defeat). Practically, we suggest to design defeaters based on the different ways in which a system might produce erroneous outputs, and analyse this suggestion with a case study of the risk classification algorithm used by the Dutch tax agency.

The connection between the probabilities of conditionals and the corresponding conditional probabilities has long been explored in the philosophical literature, but its implementation faces both technical obstacles and objections on empirical grounds. In this paper I ?rst outline the motivation for the probabilistic turn and Lewis’ triviality results, which stand in the way of what would seem to be its most straightforward implementation. I then focus on Richard Jeffrey’s ’random-variable’ approach, which circumvents these problems by giving up the notion that (...) conditionals denote propositions in the usual sense. Even so, however, the random-variable approach makes counterintuitive predictions in simple cases of embedded conditionals. I propose to address this problem by enriching the model with an explicit representation of causal dependencies. The addition of such causal information not only remedies the shortcomings of Jeffrey’s conditional, but also opens up the possibility of a uni?ed probabilistic account of indicative and counterfactual conditionals.

Conditionals with conditional constituents pose challenges for _the Thesis_, the idea that the probability of a conditional is the corresponding conditional probability. This note is concerned with two proposals for overcoming those challenges, both inspired by early work of van Fraassen: the _Bernoulli Semantics_ associated with Stalnaker and Jeffrey, and augmented with a mechanism for obtaining “local probabilities” by Kaufmann; and a proposal by Bacon which I dub _Ordinal Semantics_. Despite differences in mathematical details and emphasis of presentation, both proposals (...) lend themselves for use as a basis for a modal-theoretic interpretation of embedded conditionals. The goal of this note is to compare the two frameworks by implementing a model for the interpretation of conditionals in each, based on the same underlying probability model for non-conditional sentences. I show that in the Ordinal model, certain sentences are assigned probabilities that do not accord with intuitions. This problem is familiar from the literature on Bernoulli models and can be addressed by introducing Kaufmann-style local probabilities into Ordinal models. I then show that Bernoulli Semantics has other limitations, in that it assigns probabilities in violation of the Thesis to certain very complex formulas. The upshot is that a fusion of the theories may be our best shot at getting the predictions right. (shrink)

I argue for an account of know‐how as a capacity for practical judgment—a view I derive from Gilbert Ryle. I begin by offering an interpretation of Ryle and by correcting a number of widespread misconceptions about his views in the current debate. I then identify some problems with Ryle's account and finally present my own view which, I argue, retains Ryle's insights while avoiding his mistakes.

By using the notions of exact truth and exact falsity, one can give 16 distinct definitions of classical consequence. This paper studies the class of relations that results from these definitions in settings that are paracomplete, paraconsistent or both and that are governed by the Strong Kleene schema. Besides familiar logics such as Strong Kleene logic, the Logic of Paradox and First Degree Entailment, the resulting class of all Strong Kleene generalizations of classical logic also contains a host of unfamiliar (...) logics. We first study the members of our class semantically, after which we present a uniform sequent calculus that is sound and complete with respect to all of them. Two further sequent calculi and \ calculus) will be considered, which serve the same purpose and which are obtained by applying general methods to construct sequent calculi for many-valued logics. Rules and proofs in the SK calculus are much simpler and shorter than those of the \ and the \ calculus, which is one of the reasons to prefer the SK calculus over the latter two. Besides favourably comparing the SK calculus to both the \ and the \ calculus, we also hint at its philosophical significance. (shrink)

The rise of causality and the attendant graph-theoretic modeling tools in the study of counterfactual reasoning has had resounding effects in many areas of cognitive science, but it has thus far not permeated the mainstream in linguistic theory to a comparable degree. In this study I show that a version of the predominant framework for the formal semantic analysis of conditionals, Kratzer-style premise semantics, allows for a straightforward implementation of the crucial ideas and insights of Pearl-style causal networks. I spell (...) out the details of such an implementation, focusing especially on the notions of intervention on a network and backtracking interpretations of counterfactuals. (shrink)

Philosophers investigating the interpretation and use of conditional sentences have long been intrigued by the intuitive correspondence between the probability of a conditional `if A, then C' and the conditional probability of C, given A. Attempts to account for this intuition within a general probabilistic theory of belief, meaning and use have been plagued by a danger of trivialization, which has proven to be remarkably recalcitrant and absorbed much of the creative effort in the area. But there is a strategy (...) for avoiding triviality that has been known for almost as long as the triviality results themselves. What is lacking is a straightforward integration of this approach in a larger framework of belief representation and dynamics. This paper discusses some of the issues involved and proposes an account of belief update by conditionalization. (shrink)

The Approximate Number System (ANS) is a system that allows us to distinguish between collections based on the number of items, though only if the ratio between numbers is high enough. One of the questions that has been raised is what the representations involved in this system represent. I point to two important constraints for any account: (a) it doesn’t involve numbers, and (b) it can account for the approximate nature of the ANS. Furthermore, I argue that representations of pure (...) magnitude with vehicles that have an imprecision in the value of the unit of measurement (further clarified through a formal model from measurement theory) fit both these requirements.

This paper is devoted to Bolzano’s theory of grounding (Abfolge) in his Wissenschaftslehre. Bolzanian grounding is an explanatory consequence relation that is frequently considered an ancestor of the notion of metaphysical grounding. The paper focuses on two principles that concern grounding in the realm of conceptual sciences and relate to traditionally widespread ideas on explanations: the principles, namely, that grounding orders conceptual truths from simple to more complex ones (Simplicity), and that it comes along with a certain theoretical economy among (...) them (Economy). Being spelled out on the basis of Bolzano’s notion of deducibility (Ableitbarkeit), these principles are revealing for the question to what extent grounding can be considered a formal relation.

It is widely recognized that the innate versus acquired distinction is a false dichotomy. Yet many scientists continue to describe certain traits as “innate” and take this to imply that those traits are not acquired, or “unlearned.” This article asks what cognitive role, if any, the concept of innateness should play in the psychological and behavioural sciences. I consider three arguments for eliminating innateness from scientific discourse. First, the classification of a trait as innate is thought to discourage empirical research (...) into its developmental origin. Second, this concept lumps together a number of different biological properties that ought to be treated as distinct. Third, innateness is associated with the outmoded folk biological theory of essentialism. In response to these objections, I consider two attempts to revise the concept of innateness which aim to make it more suitable for scientific explanation and research. One proposal is that innateness can be defined in terms of the biological property of environmental canalization. On this view, a trait is innate to the extent that it is developmentally buffered against a range of different environments. Another proposal is that innateness serves as an explanatory primitive for cognitive science. This view holds that there exist a sharp boundary between psychological and biological explanations and that to identify a trait as innate means that it falls into the latter explanatory domain. This essay ends with some questions for future research. (shrink)

Within evolutionary biology, life-history theory is used to explain cross-species differences in allocation strategies regarding reproduction, maturation, and survival. Behavioral scientists have recently begun to conceptualize such strategies as a within-species individual characteristic that is predictive of behavior. Although life history theory provides an important framework for behavioral scientists, the psychometric approach to life-history strategy measurement—as operationalized by K-factors—involves conceptual entanglements. We argue that current psychometric approaches attempting to identify K-factors are based on an unwarranted conflation of functional descriptions and (...) proximate mechanisms—a conceptual mix-up that may generate unviable hypotheses and invites misinterpretation of empirical findings. The assumptions underlying generic psychometric methodology do not allow measurement of functionally defined variables; rather these methods are confined to Mayr’s proximate causal realm. We therefore conclude that K-factor scales lack validity, and that life history strategy cannot be identified with psychometrics as usual. To align theory with methodology, suggestions for alternative methods and new avenues are proposed. (shrink)

The recent explosion of interest in epigenetics is often portrayed as the dawning of a scientific revolution that promises to transform biomedical science along with developmental and evolutionary biology. Much of this enthusiasm surrounds what we call the epigenetic switch hypothesis, which regards certain examples of epigenetic inheritance as an adaptive organismal response to environmental change. This interpretation overlooks an alternative explanation in terms of coevolutionary dynamics between parasitic transposons and the host genome. This raises a question about whether epigenetics (...) researchers tend to overlook transposon dynamics more generally. To address this question, we surveyed a large sample of scientific publications on the topics of epigenetics and transposons over the past fifty years. We found that enthusiasm for epigenetics is often inversely related to interest in transposon dynamics across the four disciplines we examined. Most surprising was a declining interest in transposons within biomedical science and cellular and molecular biology over the past two decades. Also notable was a delayed and relatively muted enthusiasm for epigenetics within evolutionary biology. An analysis of scientific abstracts from the past twenty-five years further reveals systematic differences among disciplines in their uses of the term epigenetic, especially with respect to heritability commitments and functional interpretations. Taken together, these results paint a nuanced picture of the rise of epigenetics and the possible neglect of transposon dynamics, especially among biomedical scientists. (shrink)

The distinction between causal role and selected effect functions is typically framed in terms of their respective explanatory roles. However, much of the controversy over functions in genomics takes place in an investigative, not an explanatory context. Specifically, the process of component-driven functional investigation begins with the designation of some genetic or epigenetic element as functional —i.e. not junk— because it possesses properties that, arguably, suggest some biologically interesting organismal effect. The investigative process then proceeds, in a bottom-up fashion, to (...) search for those effects. I argue that this process encounters a problem reminiscent of one that Gould and Lewontin associated with the adaptationist program. Just as their stereotypical adaptationst became trapped in the myopic pursuit of one selectionist hypothesis after another, so can the investigation of CR functions in genomics lead to an unending series putative organism-level CR functions for junk DNA. This is an acute problem for genomics, because eukaryotic genomes are littered with transposable elements and their deactivated descendants which often masquerade as interesting CR-functional components and it is experimentally onerous to determine whether they lack such a function. I further argue that selectionist reasoning about TE-host coevolutionary dynamics can greatly streamline the investigative process. Importantly, selectionist hypotheses need not be well confirmed to be illuminating in this context. Informed selectionist reasoning about the strategic roles of TEs in the genome offers a corrective to the idea that most of our DNA is somehow CR functional for the organism. (shrink)

In der Auseinandersetzung mit Nietzsches Kritik der Menschenwürde nimmt dieses Buch zugleich Stellung zur aktuellen Diskussion. Wie ist die gegenwärtige Norm der Menschenwürde, wie sie auch im Grundgesetz enthalten ist, vor dem Hintergrund der Theorien des vehementen Moralkritikers Nietzsche einzuschätzen? Welchen Stellenwert hat die Würde des Menschen im Zeitalter des Posthumanismus überhaupt? Im ersten Teil skizziert der Autor zunächst die wichtigsten philosophischen Konzeptionen der Menschenwürde von Cicero bis Kant. Dabei macht er deutlich, welche Probleme die gegenwärtige Rezeption historischer Konzeptionen aufwirft. (...) Der zweite Teil ist der ausführlichen Darstellung von Nietzsches Kritik der Menschenwürde gewidmet. Daraus ergeben sich wichtige Impulse für die gegenwärtige Diskussion und konkrete Hinweise, wie ein tragbarer Begriff der Menschenwürde für die Zukunft aussehen könnte. (shrink)

Research on patients with damage to ventromedial frontal cortices suggests a key role for emotions in practical decision making. This field of investigation is often associated with Antonio Damasio’s Somatic Marker Hypothesis—a putative account of the mechanism through which autonomic tags guide decision making in typical individuals. Here we discuss two questionable assumptions—or ‘myths’—surrounding the direction and interpretation of this research. First, it is often assumed that there is a single somatic marker hypothesis. As others have noted, however, Damasio’s ‘hypothesis’ (...) admits of multiple interpretations (Dunn et al. [2006]; Colombetti [2008]). Our analysis builds upon this point by characterizing decision making as a multi-stage process and identifying the various potential roles for somatic markers. The second myth is that the available evidence suggests a role for somatic markers in the core stages of decision making, that is, during the generation, deliberation, or evaluation of candidate options. On the contrary, we suggest that somatic markers most likely have a peripheral role, in the recognition of decision points, or in the motivation of action. This conclusion is based on an examination of the past twenty-five years of research conducted by Damasio and colleagues, focusing in particular on some early experiments that have been largely neglected by the critical literature. 1 Introduction2 What is the Somatic Marker Model?3 Multiple Somatic Marker Hypotheses3.1 Are somatic markers necessary for practical decision making?3.2 Speed, accuracy, or both?3.3 At which of the five stages of decision making are somatic markers engaged?4 Anecdotal Evidence Suggests a Peripheral Role for Somatic Markers4.1 Chronic indecisiveness4.2 Extreme impulsiveness4.3 Enhanced decision making in the lab4.4 Lack of motivation. 5 Early Experiments Suggest that VMF Damage Leaves Core Processes Intact5.1 The evocative images study5.2 Five problem solving tasks6 Recent Experiments Fail to Discriminate among Alternate Versions of SMH7 Conclusion.

Most accounts of our knowledge of the successor axiom claim that this is based on the procedure of adding one. While they usually don’t claim to provide an account of how children actually acquire this knowledge, one may well think that this is how they get that knowledge. I argue that when we look at children’s responses in interviews, the time when they learn the successor axiom and the intermediate learning stages they find themselves in, that there is an empirically (...) viable alternative. I argue that they could also learn it on the basis of a method that has to do with the structure of the numeral system. Specifically, that they (1) use the syntactic structure of the numeral system and (2) attend to the leftmost digits, the one with the highest place-value. Children can learn that this is a reliable method of forming larger numbers by combining two elements. First, a grasp of the syntactic structure of the numeral system. That way they know that the leftmost digit receives the highest value. Second, an interpretation of numerals as designating cardinal values, so that they also realise that increasing or adding digits on the lefthand side of a numeral produces a larger number. There are thus two, currently equally well-supported, ways in which children might learn that there are infinitely many natural numbers. (shrink)

Polish philosophy of science has been the beneficiary of three powerful creative streams of scientific and philosophical thought. First and fore­ most was the Lwow-Warsaw school of Polish analytical philosophy founded by Twardowski and continued in their several ways by Les­ niewski, Lukasiewicz, and Tarski, the great mathematical and logical philosophers, by Kotarbinski, probably the most distinguished teacher, public figure, and culturally influential philosopher of the inter-war and post-war period, and by Ajdukiewicz, the linguistic philosopher who was intellectually sympathetic with (...) the anti-irrationalist (as he would say), logistic and meta-theoretical inquiries of the Vienna Circle. Second was independent and lively Polish Marxism, with its fine development of social research under Krzywicki, a social anthropologist and younger contemporary of Engels, and then after the war the economist Lange, the philosophers Schaff, Kolakowski, Baczko, and many others. Finally there has been a wide range of philosophical, scientific and humanistic scholar­ ship which lends its various qualities to the understanding of both the logic of science and the historical situation of the sciences: we mention only that great and humane physicist Infeld, the phenomenologist with deep epistemological interest Ingarden, the historian of scientific ideas Zawirski, the historian of philosophy and aesthetics Tatarkiewicz, and the mathematical logicians such as Mostowski and Szaniawski.

The paradox of predictability refers to situations in which, even in a deterministic universe, a correct prediction of a future action is seemingly impossible because the agent whose action is predicted is determined to act counterpredictively. In a recent contribution to this journal, Victor Gijsbers provides an example of the paradox in which the undecidability of the situation plays an essential role and claims, additionally, that this undecidability is at the root of all examples of the paradox. This paper argues, (...) first, that the latter claim is not correct because there are clear examples of the paradox in which the situation remains fully decidable. The paper argues, secondly, that, because of its reliance on rather artificial conditions and in contrast with examples referring to the physical nature of the predictor, the example presented by Gijsbers, though technically correct, has little relevance for our understanding of the role of (counter-)predictability in the context of human interactions.

Lawton’s contingency thesis states that there are no useful generalizations at the level of ecological communities because these systems are especially prone to contingent historical events. I argue that this influential thesis has been grounded on the wrong kind of evidence. CT is best understood in Woodward’s terms as a claim about the instability of certain causal dependencies across different background conditions. A recent distinction between evolution and ecology reveals what an adequate test of Lawton’s thesis would look like. To (...) date, CT remains untested. But developments in genome and molecular ecology point in a promising direction. (shrink)

As conservation biology has developed as a distinct discipline from ecology, conservation guidelines based on ecological theory have been largely cast aside in favor of theory-independent decision procedures for designing conservation reserves. I argue that this transition has failed to advance the field toward its aim of preserving biodiversity. The abandonment of island biogeography theory in favor of complementarity-based algorithms is a case in point. In what follows, I consider the four central objections raised against island biogeographic conservation guidelines, arguing (...) that they fail to undermine the credibility of this framework as a conservation tool. At best, these objections call for a more careful application of this framework to conservation problems, not its wholesale abandonment. At the same time, complementarily-based algorithms are biased in favor of networks of small reserves containing non-overlapping species. These conditions threaten to promote inbreeding depression, genetic drift and other factors that increase a population’s risk of extinction. Therefore, recent developments in the field of conservation biology have arguably not contributed to its ultimate aim of preserving the maximum amount of biodiversity in the long run. (shrink)

In this article we focus on how the language of developmental psychology shapes our conceptualisations and understandings of childrearing and of the parent-child relationship. By analysing some examples of contemporary research, policy and popular literature on parenting and parenting support in the UK and Flanders, we explore some of the ways in which normative assumptions about parenthood and upbringing are imported into these areas through the language of developmental psychology. We go on to address the particular attraction of developmental psychology (...) in the field of parenting and upbringing within our current cultural context. Drawing on the work of (among others) Zygmunt Bauman, we will show how developmental psychology, as one of the instruments that contributes to a breaking down of our existential condition into a series of well-defined, and thus apparently manageable, tasks and categories, displaces rather than confronts the possibly limitless depth of the enormity of the reality of ‘being a parent’.

“Existential risks” are risks that threaten the destruction of humanity’s long-term potential: risks of nuclear wars, pandemics, supervolcano eruptions, and so on. On standard utilitarianism, it seems, the reduction of such risks should be a key global priority today. Many effective altruists agree with this verdict. But how should the importance of these risks be assessed on a Christian moral theory? In this paper, I begin to answer this question – taking Thomas Aquinas as a reference, and the risks of (...) anthropogenic extinction as an example. I’ll suggest that on a Thomist framework, driving ourselves extinct would constitute a complete failure to fulfil our God-given nature, a radical form of hubris, and a loss of cosmological significance. So the reduction of such risks seems vital for Thomists, or Christians more broadly. Indeed, I end with the thought that these considerations are not parochially Christian, or indeed specifically religious: everyone with a similar view of mankind – as immensely valuable yet fallen and fragile – should agree that existential risks are a pressing moral concern.

A computational model of inference during story comprehension is presented, in which story situations are represented distributively as points in a high‐dimensional “situation‐state space.” This state space organizes itself on the basis of a constructed microworld description. From the same description, causal/temporal world knowledge is extracted. The distributed representation of story situations is more flexible than Golden and Rumelhart's [Discourse Proc 16 (1993) 203] localist representation.A story taking place in the microworld corresponds to a trajectory through situation‐state space. During the (...) inference process, world knowledge is applied to the story trajectory. This results in an adjusted trajectory, reflecting the inference of propositions that are likely to be the case. Although inferences do not result from a search for coherence, they do cause story coherence to increase. The results of simulations correspond to empirical data concerning inference, reading time, and depth of processing.An extension of the model for simulating story retention shows how coherence is preserved during retention without controlling the retention process. Simulation results correspond to empirical data concerning story recall and intrusion. (shrink)

On the basis of an earlier contribution to the philosophy of computer science by Amnon Eden, this essay discusses to what extent Eden’s ‘paradigms’ of computer science can be transferred or applied to software engineering. This discussion implies an analysis of how software engineering and computer science are related to each other. The essay concludes that software engineering can neither be fully subsumed by computer science, nor vice versa. Consequently, also the philosophies of computer science and software engineering—though related to (...) each other—are not identical branches of a general philosophy of science. This also implies that not all of Eden’s earlier arguments can be directly mapped from the domain of computer science into the domain of software science. After the discussion of this main topic, the essay also points to some further problems and open issues for future studies in the philosophy of software science and engineering. (shrink)

In their recent paper Bi-facial truth: a case for generalized truth values Zaitsev and Shramko [7] distinguish between an ontological and an epistemic interpretation of classical truth values. By taking the Cartesian product of the two disjoint sets of values thus obtained, they arrive at four generalized truth values and consider two “semi-classical negations” on them. The resulting semantics is used to define three novel logics which are closely related to Belnap’s well-known four valued logic. A syntactic characterization of these (...) logics is left for further work. In this paper, based on our previous work on a functionally complete extension of Belnap’s logic, we present a sound and complete tableau calculus for these logics. It crucially exploits the Cartesian nature of the four values, which is reflected in the fact that each proof consists of two tableaux. The bi-facial notion of truth of Z&S is thus augmented with a bi-facial notion of proof. We also provide translations between the logics for semi-classical negation and classical logic and show that an argument is valid in a logic for semi-classical negation just in case its translation is valid in classical logic.

Neo-Russellians like Salmon and Braun hold that: the semantic contents of sentences are structured propositions whose basic components are objects and properties, names are directly referential terms, and a sentence of the form ‘n believes that S’ is true in a context c iff the referent of the name n in c believes the proposition expressed by S in c. This is sometimes referred to as ‘the Naive Russellian theory’. In this talk, I will discuss the Naive Russellian theory primarily (...) in connection with a problem known as Schiffer’s puzzle. Schiffer first presented the puzzle as an argument against the Naive Russellian theory. Schiffer’s argument proceeds in two steps. In step one, Schiffer argues that the Naive Russellian theory is committed to two principles regarding de re belief; the special-case consequence and Frege’s constraint. Then, in step two, Schiffer argues that the special-case consequence is not consistent with Frege’s constraint. Salmon and Braun reply to Schiffer’s argument that although the Naive Russellian theory is committed to Frege’s constraint, it is not committed to the special-case consequence. However, in this paper, I will argue with a new Schiffer-case that even if the Naive Russellian theory is not committed to the special-case consequence, it is still not consistent with Frege’s constraint. Concluding, I will discuss the possibility to reject Frege’s constraint within the Naive Russellian theory. (shrink)

Wenn Klassiker in der Philosophie die Funktion haben, Medien der Diskussion zu sein, so ist Cassirers Status als philosophischer Klassiker in besonderer Weise gerechtfertigt: Seine Philosophie ist strukturell auf kritische Vermittlung ausgelegt, und zwar sowohl im Sinn eines Theoriemediums, das eine Terminologie und Methode anbietet, wie auch als Mediator im Sinne der Integration unterschiedlicher, teils widerstrebender Positionen als Problemzusammenhänge. Um diese kritisch-kommunikative Bedeutung Cassirers deutlich und zugleich nutzbar zu machen, stellen die Beiträge des Bandes jeweils Aspekte seiner Philosophie in Beziehung (...) zu anderen philosophischen und wissenschaftlichen Projekten. Hierzu gehören analytische Metaphysik, Archäologie des Wissens, neuere psychiatrische und wahrnehmungsphilosophische Ansätze, kritische Theorie, philosophische Anthropologie, Pragmatismus, Leibphänomenologie, die Pittsburgh Schule u.v.m. Der Band versteht sich dabei nicht nur als ein Beitrag zur Cassirer-Forschung, sondern will allgemeiner für die kritisch-kommunikative Haltung eintreten, die sich an Cassirer lernen lässt, um sie in die Praxis der Philosophie insgesamt zu tragen.

The dissertation provides a reconstruction of Bernard Bolzano's theory of grounding (both in early and late works) against the background of a classical conception of science and scientific explanation.

In this article, I consider a number of arguments that assume that beings who have immortal souls occupy a special position in the sphere of moral concern. First, I place these arguments in their historical and cultural contexts. Next, I formulate several conditions of adequacy that all such arguments must satisfy. Subsequently, I distinguish two different general kinds of such arguments: Inclusionary arguments attempt to use the immortality of soul as a criterion for either including someone into a sphere of (...) morality while excluding others or, at least, for elevating someone's position within this sphere. Modifying arguments attempt to strengthen or weaken moral considerations that already apply to a being included into the sphere of morality. I argue that, although some modifying arguments may fulfill all conditions of adequacy, they have very little practical importance. (shrink)

Kant wird oft als einer derjenigen großen Philosophen angesehen, dessen Werk wesentlich zum jetzigen Verständnis der Menschenrechte und Menschenwürde beigetragen hat. Kant scheint, wenn man in seine Schriften schaut, jedoch keine Theorie der Menschenrechte im modernen Sinne gehabt zu haben. Bei näherem Hinsehen zeigt sich folgender Grund: Kant unterscheidet zwischen dem bloß privaten Recht, das dem positiven Recht untergeordnet ist, und dem öffentlichen Recht, das die begrifflichen Bedingungen einer jeden legitimen, legalen Ordnung darstellt. Der Inhalt des öffentlichen Rechts wird bei (...) ihm weder direkt aus einer freistehenden Moraltheorie abgeleitet, noch aus vertraglichen Übereinkünften oder dem positiven Recht. Stattdessen soll es aus den Ermöglichungsbedingungen einer rechtmäßigen Verfassung expliziert werden, unter der allein Ansprüchen auf (ein) „Recht“ irgendeine verbindliche Autorität zukommt. Wenn man diesen Ansatz ernst nimmt, kann man kaum eine Lesart bei Kant finden, die sich mit der modernen Auffassung von Menschenrechten vereinbaren lässt. Warum aber denken dann manche, dass Kant etwas zum modernen Verständnis der Menschenrechte beizutragen hätte? So lauten denn die Leitfragen der Erörterung: Welche Auffassungen in Kants Werk kommen einem zeitgenössischen Verständnis von Menschenrechten am nächsten? Warum jedoch können diese menschrechtlich vielleicht ähnlich klingenden Auffassungen Kants den heutigen Befürwortern der Menschenrechte doch keine Quelle oder Stütze bieten? (shrink)

In this paper I argue that, from a pragmatist point of view, to know the past means to anticipate it. Accordingly, historical inquiry is directed towards the future, namely the future of the past as known. I develop this argument in three steps: (I.) Starting with A. O. Lovejoy’s criticism of Dewey’s anticipatory theory of knowledge I defend the basic claim that all knowledge, including knowledge of the past, is anticipatory (i.e. directed at future consequences). Lovejoy’s criticism shows that Dewey’s (...) statements invite misunderstandings, which have to be removed. (II.) I then turn to C. I. Lewis’ enhanced outline of a pragmatist theory of knowledge. Lewis provides epistemological arguments regarding the structural features of knowledge of the past and argues knowledge that is gained by the past’s present effects. (III.) Finally, I turn to a notable essay by E. Wind in which he stresses the intrusive and future-oriented character of historical inquiry: Documents are used as instruments for intruding into the past, asking how the past will be understood in the light of new or reconsidered evidence. This process involves anticipating the effects that a different past will have on those affected by the history in question. (shrink)

The Anthropocene concept allows human history to be imagined within the temporal framework of planetary processes. Accordingly, some environmentalists increasingly favour massively lengthening the temporal horizons of moral concern. Whilst there are defensible reasons for doing so, I wish to take issue with the ‘secular time’ perspective underlying some such approaches. To make my case, I present, in the first section, two recent manifestations of the long view perspective: a) ‘deep future’ narratives in popular climate science and futurism; b) the (...) ideas behind the Long Now Foundation. In the second section, I apply a critical lens to these perspectives via classic analyses of secular time by Charles Taylor, Hannah Arendt and Giorgio Agamben. I conclude by suggesting that these post-secular critiques should be considered alongside recent approaches to the Anthropocene and the ‘geological turn’ from new materialist perspectives. (shrink)

The Measure of a Man ist der Originaltitel der 9. Episode der 2. Staffel von Star Trek – The Next Generation, die im Mittelpunkt meiner Überlegungen steht. Hierin beabsichtigt der Kybernetikforscher und Sternenflottenoffizier Bruce Maddox, Forschung am Androiden Data durchzuführen, in der Hoffnung, schließlich Data-ähnliche Androiden erschaffen zu können. Die Forschungsprozesse implizieren jedoch Eingriffe, mit denen das Risiko einhergeht, dass Data zerstört wird, weshalb Data nicht bereit ist, an sich forschen zu lassen. Die entscheidende philosophische Frage diesbezüglich ist: Handelt es (...) sich bei Data um eine Sache oder um eine Person? Ein Weder-Noch stellt hier die plausibelste Antwort dar, wie in diesem Artikel gezeigt wird. (shrink)

The ocean’s properties and processes are now mostly known through distributed sensor networks. Among the most widespread of such networks are those that connect wave-measuring buoys. Buoys have been deployed and consulted by national meteorological organizations, state militaries, multinational corporations, and citizens. This paper zeroes in on the Directional Waverider, the most widely used buoy, manufactured since 1961 in the Netherlands by Datawell. I am interested in this buoy’s material qualities and networks of use, its life within legal frameworks, and (...) its media ecology. Staging my account against the metaphysical Italian author Italo Calvino’s “Reading a Wave,” I explore what it means to “read” a sensing technology. (shrink)
