Das Bose hat Konjunktur - und bleibt doch unberechenbar. Lassen sich dennoch angemessene Strategien des Umgangs entwickeln, die weder die prekare Faktizitat des Bosen noch seine historische Tiefendimension ausblenden? Ausgehend von dieser Leitfrage nahert sich der vorliegende, interdisziplinar breit angelegte Band dem vielschichtigen Phanomen des Bosen in praxeologischer Perspektive. So fokussiert er Moglichkeiten eines - asthetisch wie wissenschaftlich reflektierten -, guten' Umgangs mit dem Bosen. Dabei zeigt sich, dass dies nur unter Beachtung der unaufhebbaren Verwiesenheit von Gut und Bose gelingen (...) kann. Im facherubergreifenden Dialog der Beitrage entstehen so Reflexionen auf Dialektik, Differenz und Paradoxien der Fundamentalkategorien Gut und Bose von wissenschaftsethischer wie grundlagentheoretischer Brisanz.Der Band bietet einen gesonderten Schwerpunkt zu Marcel Beyers 'Kaltenburg', einem Schlusselroman zu Konrad Lorenz, dem Autor von 'Das sogenannte Bose'.

Tractatus 4.024 inspired the dominant semantics of our time: truth-conditional semantics. Such semantics is focused on possible worlds: the content of p is the set of worlds where p is true. It has become increasingly clear that such an account is, at best, defective: we need an ‘independent factor in meaning, constrained but not determined by truth-conditions’ (Yablo 2014, p. 2), because sentences can be differently true at the same possible worlds. I suggest a missing comment which, had it been (...) included in the Tractatus, would have helped semantics get this right from the start. This is my 4.0241: ‘Knowing what is the case if a sentence is true is knowing its ways of being true’: knowing a sentence’s truth possibilities and what we now call its topic, or subject matter. I show that the famous ‘fundamental thought’ that ‘the “logical constants” do not represent’ (4.0312) can be understood in terms of ways-based views of meaning. Such views also help with puzzling claims like 5.122: ‘If p follows from q, the sense of “p” is contained in the that of “q”’, which are compatible with a conception of entailment combining truth-preservation with the preservation of topicality, or of ways of being true.

Introduction and translation of “The Four Phases of Philosophy” by Franz Brentano.

The recent literature on causality has seen the introduction of several distinctions within causality, which are thought to be important for understanding the widespread scientific practice of focusing causal explanations on a subset of the factors that are causally relevant for a phenomenon. Concepts used to draw such distinctions include, among others, stability, specificity, proportionality, or actual-difference making. In this contribution, I propose a new distinction that picks out an explanatorily salient class of causes in biological systems. Some select causes (...) in complex biological systems, I argue, have the property of enabling coherent causal control of these systems. Examples of such control variables include hormones and other signaling molecules, e.g., TOR (target of rapamycin), morphogens or the products of homeotic selector genes in embryonic pattern formation. I propose an analysis of this notion based on concepts borrowed from causal graph theory. (shrink)

Comment expliquer que tant d'humains, en ce début de XXIe siècle, accordent encore foi aux discours des religions, que ce soit une religion chrétienne, musulmane ou juive? Possèdent-elles des vérités plus assurées que celles des sciences humaines ou maintiennent-elles leurs fidèles dans l'ignorance, de peur que ceux-ci ne quittent le bateau amiral des églises, des mosquées ou des synagogues? Que proposent-elles de si séduisant pour que l'on sente le besoin de suivre aveuglément leurs enseignements et que des croyants soient prêts (...) à mourir ou à occire pour elles? « Au moment où le créationnisme devient de plus en plus présent dans le cursus académique et où le programme Ethique et culture religieuse, enseigné à nos jeunes dans nos écoles, fait l'apologie du religieux et banalise la superstition, ce livre de Marcel Sylvestre a de quoi nous faire réfléchir sur l'importance à accorder à la raison. » Extrait de la préface de Louise Mailloux.

I present a formal theory of the logic and aboutness of imagination. Aboutness is understood as the relation between meaningful items and what they concern, as per Yablo and Fine’s works on the notion. Imagination is understood as per Chalmers’ positive conceivability: the intentional state of a subject who conceives that p by imagining a situation—a configuration of objects and properties—verifying p. So far aboutness theory has been developed mainly for linguistic representation, but it is natural to extend it to (...) intentional states. The proposed framework combines a modal semantics with a mereology of contents: imagination operators are understood as variably strict quantifiers over worlds with a content-preservation constraint.

We give a review and critique of jury theorems from a social-epistemology perspective, covering Condorcet’s (1785) classic theorem and several later refinements and departures. We assess the plausibility of the conclusions and premises featuring in jury theorems and evaluate the potential of such theorems to serve as formal arguments for the ‘wisdom of crowds’. In particular, we argue (i) that there is a fundamental tension between voters’ independence and voters’ competence, hence between the two premises of most jury theorems; (ii) (...) that the (asymptotic) conclusion that ‘huge groups are infallible’, reached by many jury theorems, is an artifact of unjustified premises; and (iii) that the (nonasymptotic) conclusion that ‘larger groups are more reliable’, also reached by many jury theorems, is not an artifact and should be regarded as the more adequate formal rendition of the ‘wisdom of crowds’.

Several authors have used the notion of causal specificity in order to defend non-parity about genetic causes (Waters 2007, Woodward 2010, Weber 2017, forthcoming). Non-parity in this context is the idea that DNA and some other biomolecules that are often described as information-bearers by biologists play a unique role in life processes, an idea that has been challenged by Developmental Systems Theory (e.g., Oyama 2000). Indeed, it has proven to be quite difficult to state clearly what the alleged special role (...) of genetic causes consists in. In this paper, I show that the set of biomolecules that are normally considered to be information-bearers (DNA, mRNA) can be shown to be the most specific causes of protein primary structure, provided that causal specificity is measured over a relevant space of biological possibilities, disregarding physical as well as logically possible states of the causal variables.

The Masters of Truth in Archaic Greece traces the odyssey of "truth," Aletheia, from mythoreligious to philosophical thought in archaic Greece. Marcel Detienne's starting point is a simple observation: In archaic Greece, three figures - the diviner, the bard, and the king - all share the privilege of dispensing truth by virtue of the religious power of divine memory which provides them with knowledge, both oracular and inspired, of the present, past, and future. Beginning with this definition of the (...) prerational meaning of truth, Detienne proceeds to elaborate the complex conceptual and historical contexts from which emerges the philosophical notion of truth still influencing Western philosophy today.

Is the mathematical function being computed by a given physical system determined by the system’s dynamics? This question is at the heart of the indeterminacy of computation phenomenon (Fresco et al. [unpublished]). A paradigmatic example is a conventional electrical AND-gate that is often said to compute conjunction, but it can just as well be used to compute disjunction. Despite the pervasiveness of this phenomenon in physical computational systems, it has been discussed in the philosophical literature only indirectly, mostly with (...) reference to the debate over realism about physical computation and computationalism. A welcome exception is Dewhurst’s ([2018]) recent analysis of computational individuation under the mechanistic framework. He rejects the idea of appealing to semantic properties for determining the computational identity of a physical system. But Dewhurst seems to be too quick to pay the price of giving up the notion of computational equivalence. We aim to show that the mechanist need not pay this price. The mechanistic framework can, in principle, preserve the idea of computational equivalence even between two different enough kinds of physical systems, say, electrical and hydraulic ones. (shrink)

Unification was originally introduced in automated deduction and term rewriting, but has recently also found applications in other fields. In this article, we give a survey of the results on unification obtained in two closely related, yet different, application areas of unification: description logics and modal logics.

Artefacts do not always do what they are supposed to, due to a variety of reasons, including manufacturing problems, poor maintenance, and normal wear-and-tear. Since software is an artefact, it should be subject to malfunctioning in the same sense in which other artefacts can malfunction. Yet, whether software is on a par with other artefacts when it comes to malfunctioning crucially depends on the abstraction used in the analysis. We distinguish between “negative” and “positive” notions of malfunction. A negative malfunction, (...) or dysfunction, occurs when an artefact token either does not or cannot do what it is supposed to. A positive malfunction, or misfunction, occurs when an artefact token may do what is supposed to but, at least occasionally, it also yields some unintended and undesirable effects. We argue that software, understood as type, may misfunction in some limited sense, but cannot dysfunction. Accordingly, one should distinguish software from other technical artefacts, in view of their design that makes dysfunction impossible for the former, while possible for the latter. (shrink)

Due to its emphasis on experiential interests, animal ethics tends to focus on individuals as the sole unit of moral concern. Many issues in animal ethics can be fruitfully analysed in terms of obligations towards individual animals, but some problems require reflection about collective dimensions of animal life in ways that individualist approaches can’t offer. Criticism of the individualist focus in animal ethics is not new; it has been put forward in particular by environmental ethics approaches. However, the latter tend (...) to be so far removed from the concerns of animal ethicists that both groups talk at cross purposes. We think the gap between environmental and animal ethics could be bridged by on the one hand focusing more on the collective dimensions of our concerns with animals - after all, individuals are constituted by the collective of which they are a part - and on the other hand, by showing that moral status can also be attributed to groups in an indirect way, related to the moral status of their individual members. In our paper we explore various ways of conceptualising the moral relevance of collectiveness in animal life. We draw on insights from public health ethics, as this field of inquiry has also developed - at least partly—in response to individualist approaches in human bioethics, creating more room for recognizing the value of population health, interpersonal relations, solidarity, and ways in which a collective is constituted.

"Today, more than three-quarters of a century after it was written, the critique of philosophy in this book is what makes it of such great interest.

It is often indeterminate what function a given computational system computes. This phenomenon has been referred to as “computational indeterminacy” or “multiplicity of computations.” In this paper, we argue that what has typically been considered and referred to as the challenge of computational indeterminacy in fact subsumes two distinct phenomena, which are typically bundled together and should be teased apart. One kind of indeterminacy concerns a functional characterization of the system’s relevant behavior. Another kind concerns the manner in which the (...) abstract states are interpreted. We discuss the similarities and differences between the two kinds of computational indeterminacy, their implications for certain accounts of “computational individuation” in the literature, and their relevance to different levels of description within the computational system. We also examine the inter-relationships between our proposed accounts of the two kinds of indeterminacy and the main accounts of “computational implementation.”. (shrink)

Democratic decision-making is often defended on grounds of the ‘wisdom of crowds’: decisions are more likely to be correct if they are based on many independent opinions, so a typical argument in social epistemology. But what does it mean to have independent opinions? Opinions can be probabilistically dependent even if individuals form their opinion in causal isolation from each other. We distinguish four probabilistic notions of opinion independence. Which of them holds depends on how individuals are causally affected by environmental (...) factors such as commonly perceived evidence. In a general theorem, we identify causal conditions guaranteeing each kind of opinion independence. These results have implications for whether and how ‘wisdom of crowds’ arguments are possible, and how truth-conducive institutions can be designed. (shrink)

Do the dynamics of a physical system determine what function the system computes? Except in special cases, the answer is no: it is often indeterminate what function a given physical system computes. Accordingly, care should be taken when the question ‘What does a particular neuronal system do?’ is answered by hypothesising that the system computes a particular function. The phenomenon of the indeterminacy of computation has important implications for the development of computational explanations of biological systems. Additionally, the phenomenon lends (...) some support to the idea that a single neuronal structure may perform multiple cognitive functions, each subserved by a different computation. We provide an overarching conceptual framework in order to further the philosophical debate on the nature of computational indeterminacy and computational explanation. (shrink)

I examine different arguments that could be used to establish indeterminism of neurological processes. Even though scenarios where single events at the molecular level make the difference in the outcome of such processes are realistic, this falls short of establishing indeterminism, because it is not clear that these molecular events are subject to quantum mechanical uncertainty. Furthermore, attempts to argue for indeterminism autonomously (i.e., independently of quantum mechanics) fail, because both deterministic and indeterministic models can account for the empirically observed (...) behavior of ion channels.

There are many different notions of information in logic, epistemology, psychology, biology and cognitive science, which are employed differently in each discipline, often with little overlap. Since our interest here is in biological processes and organisms, we develop a taxonomy of functional information that extends the standard cue/signal distinction. Three general, main claims are advanced here. This new taxonomy can be useful in describing learning and communication. It avoids some problems that the natural/non-natural information distinction faces. Functional information is​ ​produced (...) through exploration and stabilisation processes. (shrink)

This paper takes as a starting point a recent development in privacy-debates: the emphasis on social and institutional environments in the definition and the defence of privacy. Recognizing the merits of this approach I supplement it in two respects. First, an analysis of the relation between privacy and autonomy teaches that in the digital age more than ever individual autonomy is threatened. The striking contrast between on the one hand offline vocabulary, where autonomy and individual decision making prevail, and on (...) the other online practices is a challenge that cannot be met in a social approach. Secondly, I elucidate the background of the social approach. Its importance is not exclusively related to the digital age. In public life we regularly face privacy-moments, when in a small distinguished social domain few people are commonly involved in common experiences. In the digital age the contextual integrity model of Helen Nissenbaum has become very influential. However this model has some problems. Nissenbaum refers to a variety of sources and uses several terms to explain the normativity in her model. The notion ‘context’ is not specific and faces the reproach of conservatism. We elaborate on the most promising suggestion: an elaboration on the notion ‘goods’ as it can be found in the works of Michael Walzer and Alisdair Macintyre. Developing criteria for defining a normative framework requires making explicit the substantive goods that are at stake in a context, and take them as the starting point for decisions about the flow of information. Doing so delivers stronger and more specific orientations that are indispensible in discussions about digital privacy. (shrink)

The phenomenon of digital computation is explained (often differently) in computer science, computer engineering and more broadly in cognitive science. Although the semantics and implications of malfunctions have received attention in the philosophy of biology and philosophy of technology, errors in computational systems remain of interest only to computer science. Miscomputation has not gotten the philosophical attention it deserves. Our paper fills this gap by offering a taxonomy of miscomputations. This taxonomy is underpinned by a conceptual analysis of the design (...) and implementation of conventional computational systems at various levels of abstraction. It shows that ‘malfunction’ as it is typically used in the philosophy of artefacts only represents one type of miscomputation. (shrink)

Condorcet's famous jury theorem reaches an optimistic conclusion on the correctness of majority decisions, based on two controversial premises about voters: they are competent and vote independently, in a technical sense. I carefully analyse these premises and show that: whether a premise is justi…ed depends on the notion of probability considered; none of the notions renders both premises simultaneously justi…ed. Under the perhaps most interesting notions, the independence assumption should be weakened.

We propose a new account of indicative conditionals, giving acceptability and logical closure conditions for them. We start from Adams’ Thesis: the claim that the acceptability of a simple indicative equals the corresponding conditional probability. The Thesis is widely endorsed, but arguably false and refuted by empirical research. To fix it, we submit, we need a relevance constraint: we accept a simple conditional 'If φ, then ψ' to the extent that (i) the conditional probability p(ψ|φ) is high, provided that (ii) (...) φ is relevant for ψ. How (i) should work is well-understood. It is (ii) that holds the key to improve our understanding of conditionals. Our account has (i) a probabilistic component, using Popper functions; (ii) a relevance component, given via an algebraic structure of topics or subject matters. We present a probabilistic logic for simple indicatives, and argue that its (in)validities are both theoretically desirable and in line with empirical results on how people reason with conditionals.

Perceptual Confidence is the thesis that perceptual experiences can be probabilistic. This thesis has been defended and criticised based on a variety of phenomenological, epistemological, and explanatory arguments. One gap in these arguments is that they neglect the question of whether perceptual experiences satisfy the formal conditions that define the notion of probability to which Perceptual Confidence is committed. Here, we focus on this underexplored question and argue that perceptual experiences do not satisfy such conditions. But if they do not, (...) then ascriptions of perceptual confidence are undefined; and so, Perceptual Confidence cannot be true. (shrink)

In dem Sammelband, der als Festschrift zum 65. Geburtstag von Franz Hundsnurscher erscheint, sind 47 Beiträge zu zwei thematischen Schwerpunkten versammelt, die im Werk Hundsnurschers von zentraler Bedeutung sind: Semantik und Dialoganalyse. Im ersten Teil werden neben grundlegenden Fragen der Semantik Aspekte der semantischen Beschreibung von Phraseologismen, des Fremdwortgebrauchs und des Grundwortschatzes diskutiert; neben synchronen (meist gebrauchstheoretischen) Untersuchungen zu Einzelwörtern und Quasisynonymengruppen im Deutschen stehen sprachhistorische und kontrastive Arbeiten. Vor allem mit theoretischen und methodologischen Fragen der Dialoganalyse, mit Fragen (...) der Analyse institutioneller Kommunikation (Politik, Recht, Wirtschaft) und literarischer Dialoge setzen sich die Beiträge des zweiten Teils auseinander.
