A prominent version of emotional cognitivism is the view that emotions are preceded by awareness of value. In a recent paper, Jonathan Mitchell (2019) has attacked this view (which he calls the content-priority view). According to him, extant suggestions for the relevant type of pre-emotional evaluative awareness are all problematic. Unless these problems can be overcome, he argues, the view does not represent a plausible competitor to rivaling cognitivist views. As Mitchell supposes, the view is not mandatory since its core (...) motivations can be accommodated by competing views, too. I argue that Mitchell's case against the content-priority view is unconvincing as it misconceives the principal motivation for the view. As I show, properly reconstructed, this motivation provides a strong case for the indispensability of the view to any adequate cognitivist treatment of emotion. Moreover, Mitchell's survey of candidates for pre-emotional value awareness can be seen to rest on problematic phenomenological assumptions. (shrink)

My aim in this book is to propose a comparativist, Buddhist-Neoplatonic interpretation of the idea of “logos” in the Prologue to the Gospel according to John. To do so, I proceed in three steps. I begin with Nāgārjuna’s doctrine of emptiness. Nāgārjuna thinks that that all things are empty because they depend on causes and conditions in a way that makes it impossible for them to genuinely exist. Nevertheless, they are not completely non-existent, for they possess the appearance of something (...) that exists. This is Vasubandhu’s response to Nāgārjuna: Emptiness is not ultimate because there is the appearance of empty things. The place where this appearance unfolds is the mind, which, in an absolute sense, exists, but which, in the sense of external, objectifiable reality does not exist. Vasubandhu thus thinks of the mind as an entity that does not conform to the categories of ordinary existence. This corresponds, in turn, to what Meister Eckhart says about God. God is a Mind ("intellectus"). But due to his ontologically foundational role, God transcends ordinary existence and cannot be compared to any being. God is the mind of which Vasubandhu states that it is non-dual, transcendent knowledge. To conclude, I use this triadic constellation of Buddhist and Neoplatonic concepts to read John’s Prologue. The Prologue describes the generation of a foundational concept, “logos,” by a primordial, divine Mind. Since this Mind is, in a Buddhist sense, “empty,” the concept that it generates can be said to be absolute. It has no beginning and no cause. Thus, John’s Prologue can be interpreted as a narrative describing the foundation of reality on the ground of Buddhist concepts. (shrink)

This paper investigates the prospects of Rodney Brooks’ proposal for AI without representation. It turns out that the supposedly characteristic features of “new AI” (embodiment, situatedness, absence of reasoning, and absence of representation) are all present in conventional systems: “New AI” is just like old AI. Brooks proposal boils down to the architectural rejection of central control in intelligent agents—Which, however, turns out to be crucial. Some of more recent cognitive science suggests that we might do well to dispose of (...) the image of intelligent agents as central representation processors. If this paradigm shift is achieved, Brooks’ proposal for cognition without representation appears promising for full-blown intelligent agents—Though not for conscious agents. (shrink)

Cumulative cultural knowledge [CCK], the knowledge we acquire via social learning and has been refined by previous generations, is of central importance to our species’ flourishing. Considering its importance, we should expect that our best epistemological theories can account for how this happens. Perhaps surprisingly, CCK and how we acquire it via cultural learning has only received little attention from social epistemologists. Here, I focus on how we should epistemically evaluate how agents acquire CCK. After sampling some reasons why extant (...) theories cannot account for CCK, I suggest that things aren’t as bleak as they might look. I explain how agents deserve epistemic credit for how CCK is transmitted in cultural learning by promoting a central need of their social group: The efficient and safe transmission of CCK. A good initial fit exists between this observation and Greco’s knowledge-economy framework. Ultimately, however, Greco’s account doesn’t straightforwardly account for CCK because of its strict focus on testimony. I point out two issues in the framework due to this focus. The resulting view advocates giving epistemic credit to agents when they act to promote their communities’ epistemic needs in the right way and highlights the various ways in which agents come to do this.

A shared narrative in the literature on the evolution of cooperation maintains that social _learning_ evolves early to allow for the transmission of cumulative culture. Social _norms_, whilst present at the outset, only rise to prominence later on, mainly to stabilise cooperation against the threat of defection. In contrast, I argue that once we consider insights from social epistemology, an expansion of this narrative presents itself: An interesting kind of social norm — an epistemic coordination norm — was operative in (...) early and important instances of specialised social learning. I show how there’s a need for such norms in two key social learning strategies and explain how this need is constituted. In assessor-teaching (e.g. Castro et al., 2019b, 2021), epistemic coordination norms allow agents to coordinate around the _content_ of social learning, i.e., what is to be known and how this is to be done. These norms also allow agents to coordinate around the form of cultural learning in what’s sometimes called strategic social learning (Laland, 2004; Hoppitt & Laland, 2013; Heyes, 2018, Chap. 5) and elsewhere. Broadly speaking, this concerns how cultural learning is organised within the social group. The upshot is that the evolution of social learning and social norms are intertwined in important and underappreciated ways from early on. The above matters as it informs our views about the evolution of social norms more generally. Truly _social_ norms emerged to coordinate a plurality of complex behaviours and interactions, amongst them specialised social learning. I substantiate this view by contrasting it with Jonathan Birch’s views on the evolution of norms. What results is a general but cohesive narrative on the early evolution of social norms. (shrink)

The paper presents a paradoxical feature of computational systems that suggests that computationalism cannot explain symbol grounding. If the mind is a digital computer, as computationalism claims, then it can be computing either over meaningful symbols or over meaningless symbols. If it is computing over meaningful symbols its functioning presupposes the existence of meaningful symbols in the system, i.e. it implies semantic nativism. If the mind is computing over meaningless symbols, no intentional cognitive processes are available prior to symbol grounding. (...) In this case, no symbol grounding could take place since any grounding presupposes intentional cognitive processes. So, whether computing in the mind is over meaningless or over meaningful symbols, computationalism implies semantic nativism. (shrink)

This paper investigates the view that digital hypercomputing is a good reason for rejection or re-interpretation of the Church-Turing thesis. After suggestion that such re-interpretation is historically problematic and often involves attack on a straw man (the ‘maximality thesis’), it discusses proposals for digital hypercomputing with Zeno-machines , i.e. computing machines that compute an infinite number of computing steps in finite time, thus performing supertasks. It argues that effective computing with Zeno-machines falls into a dilemma: either they are specified such (...) that they do not have output states, or they are specified such that they do have output states, but involve contradiction. Repairs though non-effective methods or special rules for semi-decidable problems are sought, but not found. The paper concludes that hypercomputing supertasks are impossible in the actual world and thus no reason for rejection of the Church-Turing thesis in its traditional interpretation. (shrink)

In this paper, I offer an analysis of the radical disagreement over the adequacy of string theory. The prominence of string theory despite its notorious lack of empirical support is sometimes explained as a troubling case of science gone awry, driven largely by sociological mechanisms such as groupthink (e.g. Smolin 2006). Others, such as Dawid (2013), explain the controversy by positing a methodological revolution of sorts, according to which string theorists have quietly turned to nonempirical methods of theory assessment given (...) the technological inability to directly test the theory. The appropriate response, according to Dawid, is to acknowledge this development and widen the canons of acceptable scientific methods. As I’ll argue, however, the current situation in fundamental physics does not require either of these responses. Rather, as I’ll suggest, much of the controversy stems from a failure to properly distinguish the “context of justification” from the “context of pursuit”. Both those who accuse string theorists of betraying the scientific method and those who advocate an enlarged conception of scientific methodology objectionably conflate epistemic justification with judgements of pursuit-worthiness. Once we get clear about this distinction and about the different norms governing the two contexts, the current situation in fundamental physics becomes much less puzzling. After defending this diagnosis of the controversy, I’ll show how the argument patterns that have been posited by Dawid as constituting an emergent methodological revolution in science are better off if reworked as arguments belonging to the context of pursuit.

In this paper, I consider the relationship between Inference to the Best Explanation and Bayesianism, both of which are well-known accounts of the nature of scientific inference. In Sect. 2, I give a brief overview of Bayesianism and IBE. In Sect. 3, I argue that IBE in its most prominently defended forms is difficult to reconcile with Bayesianism because not all of the items that feature on popular lists of “explanatory virtues”—by means of which IBE ranks competing explanations—have confirmational import. (...) Rather, some of the items that feature on these lists are “informational virtues”—properties that do not make a hypothesis \ more probable than some competitor \ given evidence E, but that, roughly-speaking, give that hypothesis greater informative content. In Sect. 4, I consider as a response to my argument a recent version of compatibilism which argues that IBE can provide further normative constraints on the objectively correct probability function. I argue that this response does not succeed, owing to the difficulty of defending with any generality such further normative constraints. Lastly, in Sect. 5, I propose that IBE should be regarded, not as a theory of scientific inference, but rather as a theory of when we ought to “accept” H, where the acceptability of H is fixed by the goals of science and concerns whether H is worthy of commitment as research program. In this way, IBE and Bayesianism, as I will show, can be made compatible, and thus the Bayesian and the proponent of IBE can be friends. (shrink)

The Preface Paradox is often discussed for its implications for rational belief. Much less discussed is a variant of the Preface Paradox for knowledge. In this paper, I argue that the most plausible closure-friendly resolution to the Preface Paradox for Knowledge is to say that in any given context, we do not know much. I call this view “Socraticism”. I argue that Socraticism is the most plausible view on two accounts—(1) this view is compatible with the claim that most of (...) our knowledge ascriptions are true, and (2) provided that (1) is true, the costs of accepting Socraticism are much less than the costs of accepting any other resolution to the Paradox. I argue for (1) in Section 2 by developing a question-sensitive contextualist model for knowledge that shows how Socraticism is compatible with the claim that most of our knowledge ascriptions are true. I also argue how this contextualist model can achieve this result where other contextualist models fail. I then consider other closure-friendly solutions to the paradox in Section 3 and show how accepting those solutions forces us to give up a number of plausible epistemic principles. (shrink)

Rollback arguments focus on long sequences of actions with identical initial conditions in order to explicate the luck problem that indeterminism poses for libertarian free will theories (i.e. the problem that indeterministic actions appear arbitrary in a free-will undermining way). In this paper, I propose a rollback argument for probability incompatibilism, i.e. for the thesis that free will is incompatible with all world-states being governed by objective probabilities. Other than the most prominently discussed rollback arguments, this argument explicitly focusses on (...) the ability to act otherwise. It argues that the negligible probability of the relative frequencies in overall rollback patterns being relevantly different indicates that even the ability to act otherwise with regard to individual actions is not free-will enabling. My proposed argument provides probability incompatibilists with a tool to argue against a classical event-causal response to the luck problem, while it can still motivate an agent-causal response to it.

In this article, I will provide a critical overview of the form of non-deductive reasoning commonly known as “Inference to the Best Explanation” (IBE). Roughly speaking, according to IBE, we ought to infer the hypothesis that provides the best explanation of our evidence. In section 2, I survey some contemporary formulations of IBE and highlight some of its putative applications. In section 3, I distinguish IBE from C.S. Peirce’s notion of abduction. After underlining some of the essential elements of IBE, (...) the rest of the entry is organized around an examination of various problems that IBE confronts, along with some extant attempts to address these problems. In section 4, I consider the question of when a fact requires an explanation, since presumably IBE applies only in cases where some explanation is called for. In section 5, I consider the difficult question of how we ought to understand IBE in light of the fact that among philosophers, there is significant disagreement about what constitutes an explanation. In section 6, I consider different strategies for justifying the truth-conduciveness of the explanatory virtues, e.g., simplicity, unification, scope, etc., criteria which play an indispensable role in any given application of IBE. In section 7, I survey some of the most recent literature on IBE, much of which consists of investigations of the status of IBE from the standpoint of the Bayesian philosophy of science. (shrink)

Definition of the problem The umbrella term “explicability” refers to the reduction of opacity of artificial intelligence (AI) systems. These efforts are challenging for medical AI applications because higher accuracy often comes at the cost of increased opacity. This entails ethical tensions because physicians and patients desire to trace how results are produced without compromising the performance of AI systems. The centrality of explicability within the informed consent process for medical AI systems compels an ethical reflection on the trade-offs. Which (...) levels of explicability are needed to obtain informed consent when utilizing medical AI? Arguments We proceed in five steps: First, we map the terms commonly associated with explicability as described in the ethics and computer science literature, i.e., disclosure, intelligibility, interpretability, and explainability. Second, we conduct a conceptual analysis of the ethical requirements for explicability when it comes to informed consent. Third, we distinguish hurdles for explicability in terms of epistemic and explanatory opacity. Fourth, this then allows to conclude the level of explicability physicians must reach and what patients can expect. In a final step, we show how the identified levels of explicability can technically be met from the perspective of computer science. Throughout our work, we take diagnostic AI systems in radiology as an example. Conclusion We determined four levels of explicability that need to be distinguished for ethically defensible informed consent processes and showed how developers of medical AI can technically meet these requirements.

Intuitions about intentional action have turned out to be sensitive to normative factors: most people say that an indifferent agent brings about an effect of her action intentionally when it is harmful, but unintentionally when it is beneficial. Joshua Knobe explains this asymmetry, which is known as ‘the Knobe effect’, in terms of the moral valence of the effect, arguing that this explanation generalizes to other asymmetries concerning notions as diverse as deciding and being free. I present an alternative explanation (...) of the Knobe effect in terms of normative reasons. This explanation generalizes to other folk psychological notions such as deciding, but not to such notions as being free. I go on to argue, against Knobe, that offering a unified explanation of all the asymmetries he discusses is in fact undesirable. (shrink)

Recent years have witnessed intensive efforts to specify which requirements ethical artificial intelligence (AI) must meet. General guidelines for ethical AI consider a varying number of principles important. A frequent novel element in these guidelines, that we have bundled together under the term explicability, aims to reduce the black-box character of machine learning algorithms. The centrality of this element invites reflection on the conceptual relation between explicability and the four bioethical principles. This is important because the application of general ethical (...) frameworks to clinical decision-making entails conceptual questions: Is explicability a free-standing principle? Is it already covered by the well-established four bioethical principles? Or is it an independent value that needs to be recognized as such in medical practice? We discuss these questions in a conceptual-ethical analysis, which builds upon the findings of an empirical document analysis. On the example of the medical specialty of radiology, we analyze the position of radiological associations on the ethical use of medical AI. We address three questions: Are there references to explicability or a similar concept? What are the reasons for such inclusion? Which ethical concepts are referred to? (shrink)

Some properties are causally relevant for a certain effect, others are not. In this paper we describe a problem for our understanding of this notion and then offer a solution in terms of the notion of a program explanation.

Wie viele empirische Daten auch immer wir zusammentragen mögen: es sind nie ausschließlich diese Daten, die bei unserer theoretischen Arbeit den Ausschlag geben. Ob wir eine Naturwissenschaftliche Theorie akzepieren, hängt nicht alleine davon ab, wie exakt sie zur Empirie passt ( also zu den Daten aus Beobachtungen und Versuchsergebnissen), sondern auch von weiteren - außerempirischen - Kriterien. Eines dieser Kriterien stützt sich auf unseren Schönheitssinn. Wie ein Blick in die Geschichte der Physik ohne jeden Zweifel lehrt, spielt der Sinn für (...) Ästhetik eine herausragende Rolle für den wissenschaftlichen Fortschritt. Gerade die Genies der neuzeitlichen und modernen Physik setzen bei ihrer bahnbrechenden Forschung immer wieder auf das Schöne. Das ist eine rätselhafte Tatsache, die wir deshalb ernstnehmen sollten, weil sich die zunächst ästhetisch optimierten Theorien im weiteren Geschichtsverlauf immer wieder empirisch als verblüffend erfolgreich herausgestellt haben.

May lethal autonomous weapons systems—‘killer robots ’—be used in war? The majority of writers argue against their use, and those who have argued in favour have done so on a consequentialist basis. We defend the moral permissibility of killer robots, but on the basis of the non-aggregative structure of right assumed by Just War theory. This is necessary because the most important argument against killer robots, the responsibility trilemma proposed by Rob Sparrow, makes the same assumptions. We show that the (...) crucial moral question is not one of responsibility. Rather, it is whether the technology can satisfy the requirements of fairness in the re-distribution of risk. Not only is this possible in principle, but some killer robots will actually satisfy these requirements. An implication of our argument is that there is a public responsibility to regulate killer robots ’ design and manufacture. (shrink)

We develop a Bayesian framework for thinking about the way evidence about the here and now can bear on hypotheses about the qualitative character of the world as a whole, including hypotheses according to which the total population of the world is infinite. We show how this framework makes sense of the practice cosmologists have recently adopted in their reasoning about such hypotheses.

Was wissen Sie über Kosovo? Nicht genug. Nicht genug jedenfalls über objektive, wertfrei vorgegebene Fakten, mit deren Hilfe man verantwortungsethische Bewertungen des NATO-Angriffs begründen könnte. Trotzdem halte ich drei wertende Aussagen über den Kosovo-Konflikt für vernünftig. Sie lauten (in alphabetischer Reihenfolge): Der bewaffnete Kampf der Albaner im Kosovo war moralisch falsch. Die Militäreinsätze der Serben im Kosovo waren moralisch falsch (schon vor Beginn der NATO-Bombardements und erst recht danach). Und schliesslich: Die Luftschläge des Westens gegen Serbien waren moralisch falsch. Insbesondere (...) diese letzte Behauptung ist der Zielpunkt des Aufsatzes. Mein Plädoyer für diese Behauptung verläuft auf einem dritten Weg zwischen der gesinnungsethischen Position pazifistischer Rigoristen und der verantwortungsethischen Position ihrer Kontrahenten. Die grundlegende Richtlinie für meine Untersuchung besteht darin, keine Behauptungen als objektiv auszugeben, die in Wirklichkeit auf Wertungen beruhen. Schon beim Blick auf die Vorkriegs- und Kriegsgeschehnisse im Kosovo kommen wir nicht ohne die Hilfe von Werten aus; und ich plädiere dafür, diese Geschehnisse im Lichte einer verzweifelten Menschenliebe anzusehen: Daraus ergibt sich eine neue Form von Pazifismus.

The theory and philosophy of artificial intelligence has come to a crucial point where the agenda for the forthcoming years is in the air. This special volume of Minds and Machines presents leading invited papers from a conference on the “Philosophy and Theory of Artificial Intelligence” that was held in October 2011 in Thessaloniki. Artificial Intelligence is perhaps unique among engineering subjects in that it has raised very basic questions about the nature of computing, perception, reasoning, learning, language, action, interaction, (...) consciousness, humankind, life etc. etc. – and at the same time it has contributed substantially to answering these questions. There is thus a substantial tradition of work, both on AI by philosophers and of theory within AI itself. - The volume contains papers by Bostrom, Dreyfus, Gomila, O'Regan and Shagrir. (shrink)

In this paper, I critically evaluate several related, provocative claims made by proponents of data-intensive science and “Big Data” which bear on scientific methodology, especially the claim that scientists will soon no longer have any use for familiar concepts like causation and explanation. After introducing the issue, in Section 2, I elaborate on the alleged changes to scientific method that feature prominently in discussions of Big Data. In Section 3, I argue that these methodological claims are in tension with a (...) prominent account of scientific method, often called “Inference to the Best Explanation”. Later on, in Section 3, I consider an argument against IBE that will be congenial to proponents of Big Data, namely, the argument due to Roche and Sober Analysis, 73:659–668, that “explanatoriness is evidentially irrelevant.” This argument is based on Bayesianism, one of the most prominent general accounts of theory-confirmation. In Section 4, I consider some extant responses to this argument, especially that of Climenhaga Philosophy of Science, 84:359–368,. In Section 5, I argue that Roche and Sober’s argument does not show that explanatory reasoning is dispensable. In Section 6, I argue that there is good reason to think explanatory reasoning will continue to prove indispensable in scientific practice. Drawing on Cicero’s oft-neglected De Divinatione, I formulate what I call the “Ciceronian Causal-nomological Requirement”, which states, roughly, that causal-nomological knowledge is essential for relying on correlations in predictive inference. I defend a version of the CCR by appealing to the challenge of “spurious correlations,” chance correlations which we should not rely upon for predictive inference. In Section 7, I offer some concluding remarks. (shrink)

In the seventeenth century, Newton used bis famous prism to found the physics of spectral light, thus revolutionising our thinking about colours; more than a hundred years later, Goethe protested against Newton's theory and discovered a number of new prismatic colour phenomena. Did these episodes in the history of science have any influence on the visual arts? For a decade now my visits to art museums have had an agenda: I have been looking for nineteenth-century paintings with certain spectral colour (...) (which will be described in the first half of this paper). While my search has been unsuccessful in traditional Western art, I found what I was looking for in Japa­nese art: in woodblock prints by Hokusai and Hiroshige. This is surprising; little Western science had reached Japan in their time. The second half of the paper pre­sents this riddle, which I am nowhere near solving. Even without a solution, however, a riddle can be instructive. In this case, it may help to bring into focus the fascinating exchange between two distant cultures. Much has been written on the cultural relativ­ity of colour perception, colour systematisation and colour aesthetics; I want to intro­duce a new and so far unknown case that might contribute to this debate - though the debate itself remains beyond the scope of this paper.

"Data mining is not an invasion of privacy because access to data is only by machines, not by people": this is the argument that is investigated here. The current importance of this problem is developed in a case study of data mining in the USA for counterterrorism and other surveillance purposes. After a clarification of the relevant nature of privacy, it is argued that access by machines cannot warrant the access to further information, since the analysis will have to be (...) made either by humans or by machines that understand. It concludes that the current data mining violates the right to privacy and should be subject to the standard legal constraints for access to private information by people. (shrink)

This paper investigates a problem about freedom of information. Although freedom of information is generally considered desirable, there are a number of areas where there is substantial agreement that freedom of information should be limited.

This category includes information the use of which (...) would be morally wrong as well as some of what may be called "corrupting" information. Some such information should not be spread at all and some should be very limited in its spread. (shrink)

Verstehen wir die Rede vom seelischen Leben außerhalb der Na­tur? Gewisse Fassungen des Naturalismus bestreiten das. Diese Formen von Natu­ralismus möchte ich widerlegen.

Crispin Wright hat die bislang beste Rekonstruktion von Putnams Beweis gegen die skeptische Hypothese vom Gehirn im Tank vorgelegt. Aber selbst in Wrights Fassung hat der Beweis einen Mangel: Er wird mithilfe eines Prädikates wie z.B. "Tiger" geführt und funktioniert nur, wenn man sich darauf verlassen kann, dass es Tiger wirklich gibt. Aber die Skeptikerin bestreitet, über die Existenz von Tigern bescheid zu wissen. Das Problem lässt sich dadurch beheben, dass man den Beweis – statt mit dem extensionalen Begriff der (...) Referenz (wie bei Wright) – mit Intensionen führt. Zudem sollte der Beweis transzendental laufen, also einzig und allein auf den sprachlichen Voraussetzungen beruhen, die auch die Skeptikerin zur Formulierung ihrer Tank-Hypothese benötigt. -/- The best reconstruction of Putnam's brain-in-a-vat argument is due to Crispin Wright. But even Wright's version of the argument is not convincing. It employs predicates such as 'tiger' and reaches the conclusion only if we can rely upon the existence of tigers; and the skeptic disputes our knowledge regarding tigers. The problem is not insuperable: The argument must be run, not with the extensionalistic notion of reference (as in Wright's version), but with intensions. Furthermore, the argument should have a transcendental form; it should exclusively rely on conditions that are needed by the skeptic for formulating her own position. (shrink)

Was sollen wir von einem seelischen Leben außerhalb der Natur halten? In seinem Kommentar zu meiner metaphysischen Provokation „Jenseits" legt Thomas Sukopp nahe, dass jede Evidenz gegen jene Möglichkeit spreche.

Nicht einmal Wahrscheinlichkeiten können wir gegen das Jenseits ins Feld führen, denn Wahrscheinlichkeitsbehauptungen beruhen auf Naturbeobachtung- und der Streit dreht sich um etwas außerhalb der Natur. Genauso wenig helfen Kriterien (...) wie Einfachheit oder Sparsamkeit.

Die deutsche Beteiligung am Krieg in Afghanistan zielte erstens darauf ab, in Afghanistan für Demokratie und Menschenrechte zu sorgen; zweitens darauf, an Ort und Stelle für Sicherheit zu sorgen (ohne die kein wirtschaftlicher und gesellschaftlicher Aufbau möglich ist); und drittens darauf, unsere eigene Sicherheit (etwa vor terroristischen Angriffen) zu erhöhen. Diese Ziele sind erstrebenswert – aber es ist mehr als fraglich, ob jemals realistische Aussicht bestand, diese Ziele zu erreichen. Wir haben in Afghanistan nach der optimalen Mischung aus zivilen und (...) militärischen Maßnahmen gesucht – und haben sie nicht gefunden. War die Intervention zum Scheitern verurteilt? Nein; aber zu keinem Zeitpunkt verfügten wir über das für Erfolg erforderliche Wissen. Wir haben versucht, in ein chaotisches System einzugreifen, das sich während der Intervention immer wieder änderte. Wir haben zu langsam dazugelernt, und wir hätten auch kaum schneller lernen können, denn dieser Krieg ist Chaos, also unkontrollierbar (so wie viele andere Kriege auch). Das bedeutet, dass sich die Kriegsbefürworter und -planer maßlos überschätzt haben – technisch, militärisch, politisch, erkenntnistheoretisch und ethisch. Nicht die Pazifisten waren Traumtänzer in der Debatte über den Afghanistan-Krieg. Diese Thesen begründe ich angesichts des Stands der Dinge vom Winter 2010/1. Ich plädiere für einen sofortigen Abzug aus Afghanistan – und für noble Gesten gegenüber den Afghanen, die an unserer Seite Kopf & Kragen riskiert haben. (shrink)

Goethe und Schelling begannen ihre Zusammenarbeit mit intensiven optischen Experimenten. Schelling lernte von Goethe, dass sich viele Farbphänomene bipolar anordnen lassen und dass eine optische Symmetrie bzw. Dualität zwischen weißem Licht und schwarzem Schatten besteht. Goethe lernte von Schelling, dass man das Prinzip der Bipolarität als forschungsleitende Idee verstehen kann (als eine regulative Idee in Kants Sinn). In der optischen Forschung kommt man mit dieser Idee wesentlich weiter, als gemeinhin angenommen wird; ihr Potential ist bis heute nicht ausgeschöpft. Sie ist (...) u.a. deshalb in der Versenkung verschwunden, weil ihre Verfechter mit ihr unseriös über die Stränge schlugen – außerhalb der Optik. Wenn sich das hätte vermeiden lassen, wäre Goethes Farbenlehre von Physikern möglicherweise weniger feindselig aufgenommen worden. Pech für Goethe. (shrink)

Analytische Sätze, die kraft Definition wahr sein sollen, schaden der Naturwissenschaft oder trivialisieren ihren Fortschritt: So lautet einer der Kritikpunkte, die Quine in seinem Feldzug gegen die Unterscheidung zwischen synthetischen und analytischen Sätzen vorgebracht hat. Sie schaden, so Quine, weil sie nicht revidiert werden dürfen und damit die Wahlfreiheit beim Theorienwandel über Gebühr einschränken. (Hätte sich z.B. Einstein vom analytischen Status der newtonischen Impulsdefinition beeindrucken lassen, so hätte er die Relativitätstheorie nicht formulieren können). Oder sie trivialisieren den Fortschritt, weil sich (...) durch Preisgabe analytischer Sätze bloß die Sprache ändert – und wie soll uns eine Änderung der Begriffe vorwärtsbringen? Um dieser Herausforderung zu begegnen, müssen wir Sprach- und Theorienwandel auseinanderdividieren. Im Falle einer wissenschaftlichen Revolution findet beides gleichzeitig statt. Trotzdem kann man die Beobachtungskonsequenzen der neuen Theorie (mithilfe des Ramsey-Satzes) mit denen der alten vergleichen; und mithilfe des Carnap-Satzes kann man den jeweiligen analytischen Anteil der beiden Theorien extrahieren. Es war Carnaps Fehler, diesen Schachzug zur Definition des Begriffs vom analytischen Satz heranzuziehen. Umgekehrt wird ein Schuh draus: Mithilfe einer holismustauglichen Definition von "analytisch" lässt sich zeigen, dass die Carnap-Sätze analytisch sind. Hier die Grundidee der fraglichen Definition: Ein Satz ist analytisch, wenn sich der empirische Gehalt keiner Gesamttheorie dadurch ändert, dass man ihr den Satz einpflanzt. (shrink)

Als Goethe in seiner monumentalen Farbenlehre (1810) versuchte, Newtons Theorie des Lichts und der Farben anzugreifen, setzte er eine Methode ein, die er als Vermannigfachung der Erfahrungen bezeichnete: Er variierte verschiedene Parameter der newtonischen Experimente, um neuen Spielraum für Alternativen zur Theorie Newtons zu gewinnen. Dabei erzielte er durchaus Erfolge. U.a. entdeckte er das Komplement zum newtonischen Spektrum (das aussieht wie dessen Farbnegativ und durch Vertauschung der Rollen von Licht und Finsternis entsteht). Ingo Nussbaumer hat Goethes Methode kongenial fortgeführt. Dabei (...) hat er sechs weitere Farbspektren entdeckt. Sie entstehen, wenn man anstelle des Hell/Dunkel-Kontrasts (in Newtons und Goethes Experimenten) mit Paaren von Komplementärfarben arbeitet. Die neuen Farbspektren sehen genauso differenziert aus wie Newtons und Goethes Spektrum; doch anders als diese enthalten sie die unbunten "Farben" Schwarz und Weiss. Die vielfältigen Ordnungsbeziehungen und Symmetrien, die Ingo Nussbaumer in der Farbenwelt der insgesamt acht Spektren ausgemacht hat, verhelfen uns vielleicht zu einem tieferen Verständnis der Prinzipien menschlicher Farbwahrnehmung. Abgesehen davon haben sie einen hohen ästhetischen Reiz. Und sie regen dazu an, über kontrafaktische Verläufe der Wissenschaftsgeschichte zu spekulieren: Wie gut hätte sich Newtons Theorie des Lichts und der Farben in den Jahren nach ihrer Veröffentlichung (1672) durchsetzen können, wenn damals das newtonische Spektrum zusammen mit seinen sieben Gegenstücken bekannt geworden und daher nicht das einzige Spektrum gewesen wäre, mit dem die Theorie hätte fertigwerden müssen?

The present article focuses on the idea that divine nature is prior to being. This idea was first articulated in John of Scythopolis’s commentary on Pseudo-Dionysius. It was adopted by Maximus Confessor and re-used in Meister Eckhart’s first Quaestio Parisiensis. The main tenet of this idea is that, if God is the origin of being, he must be more fundamental than being. Thus, being cannot be identical to divine nature. The conclusion that can be drawn from the discussion of this (...) idea is that the importance that has been traditionally attached to the "Exodusmetaphysik" must be reconsidered, and that the pro-ontological conception of divine nature constitutes an autonomous tradition in Christian thought.

In this paper, I examine Cicero’s oft-neglected De Divinatione, a dialogue investigating the legitimacy of the practice of divination. First, I offer a novel analysis of the main arguments for divination given by Quintus, highlighting the fact that he employs two logically distinct argument forms. Next, I turn to the first of the main arguments against divination given by Marcus. Here I show, with the help of modern probabilistic tools, that Marcus’ skeptical response is far from the decisive, proto-naturalistic assault (...) on superstition that it is sometimes portrayed to be. Then, I offer an extended analysis of the second of the main arguments against divination given by Marcus. Inspired by Marcus’ second main argument, I formulate, explicate, and defend a substantive principle of scientific methodology that I call the “Ciceronian Causal-Nomological Requirement” (CCR). Roughly, this principle states that causal knowledge is essential for relying on correlations in predictive inference. Although I go on to argue that Marcus’ application of the CCR in his debate with Quintus is dialectically inadequate, I conclude that De Divinatione deserves its place in Cicero’s philosophical corpus, and that ultimately, its significance for the history and philosophy of science ought to be recognized.

Der erste amerikanische Krieg von 1991 gegen Saddam Hussein war moralisch falsch. Man muss kein radikaler Pazifist sein, um zu diesem Urteil zu kommen, denn dies Urteil ergibt sich auch dann, wenn man die drei Kriegsziele ernst und beim Wort nimmt, die George Bush zur Rechtfertigung des Kriegs angeführt hat. In der Tat sind es auf den ersten Blick löbliche Ziele, Kuwait von der Besatzung durch irakische Truppen zu befreien, Saddam Husseins Militärmacht einzudämmen und für eine gerechte Weltordnung zu kämpfen. (...) Doch wenn man die Opfer in den Blick nimmt, die der Krieg kostet, ändert sich das Bild – die Kriegsopfer wiegen schwerer als der erhoffte Vorteil des Kriegs, und also war der Krieg moralisch unverantwortlich.

In der Schlickvorlesung ("Warte, bis Du stirbst") habe ich im Detail Geschichten erzählt, die jemand erleben müsste, um sein Weiterleben nach dem Tod zu verifizieren. Diese Geschichten hatten eine dualistische Stoßrichtung, lieferten aber kein Argument zugunsten des Dualismus, kein Argument zugunsten der Möglichkeit, dass unsere Seele auch ohne Körper weiterlebt. Niko Strobach hat implizite Argumente aus der Schlickvorlesung herausgelesen und kritisiert. In meiner Reaktion auf diese Kritik spreche ich mich für eine epistemische Lesart der dualistischen Möglichkeit aus; ob der Dualismus (...) metaphysisch möglich ist, finde ich irrelevant. Zudem verteidige ich das von mir benutzte – im weitesten Sinne empiristische – Sinnkriterium; ich biete eine narrative und eine cineastische Version des Kriteriums an: Ein Satz hat guten Sinn, wenn sich eine konkrete Geschichte denkbarer Wahrnehmungserlebnisse erzählen bzw. verfilmen lässt, denen der Erlebende Evidenzen für oder gegen den Satz entnehmen kann. Da die Geschichten von der Auferstehung des Fleisches, die Niko Strobach der christlichen Tradition entnimmt, heutzutage narrativ suboptimal sind, bleibe ich bei der These aus der Schlickvorlesung: Die Frage des Weiterlebens nach dem Tod hat guten Sinn, und um das nachzuweisen, eignen sich am besten dualistische Geschichten.

In this article, I consider an important challenge to the popular theory of scientific inference commonly known as ‘inference to the best explanation’, one that has received scant attention.1 1 The problem is that there exists a wide array of rival models of explanation, thus leaving IBE objectionably indeterminate. First, I briefly introduce IBE. Then, I motivate the problem and offer three potential solutions, the most plausible of which is to adopt a kind of pluralism about the rival models of (...) explanation. However, I argue that how ranking explanations on this pluralistic account of IBE remains obscure and pluralism leads to contradictory results. In light of these objections, I attempt to dissolve the problem by showing why IBE does not require a ‘model’ of explanation and by giving an account of what explanation consists in within the context of IBE.

Zwar wissen wir nicht objektiv und wertfrei, wieviel CO2 wir der Atmosphäre noch aufbürden dürfen, bevor es zur Katastrophe kommt. Doch für behutsame, vorsorgliche Leute steht fest, dass das Klimaproblem die Menschheit bedroht. (In dieser Aussage vermengen sich unentwirrbar deskriptive und evaluative Komponenten – was uns im Lichte der neueren Metaethik nicht zu wundern braucht). Wie müsste eine faire Lösung des Klimaproblems aussehen? Wie sollten wir Pflichten und finanzielle Lasten der nötigen CO2-Reduktionen verteilen, wenn es dabei gerecht zugehen soll? In (...) meiner Antwort auf diese ethischen Fragen stütze ich mich auf einen Grundsatz, den Angela Merkel formuliert hat: Jeder Mensch hat das Recht, genauso viel CO2-Emissionen zu verursachen wie jeder andere. In einem ersten Schritt soll die Steigerung der weltweiten CO2-Emissionen angehalten werden. Um das auf gerechte Weise zu bewerkstelligen, werden in feiner Stückelung Rechte zum CO2-Ausstoß (die sog. Mikro-Zertifikate) ausgegeben, und zwar zunächst für genau so viel CO2, wie die Menschheit zur Zeit insgesamt pro Jahr in die Luft bläst. Wer CO2 emittieren will, gleichgültig wo, wie und wozu, darf das nur gegen Entwertung einer entsprechenden Anzahl an Mikro-Zertifikaten, sonst macht er sich strafbar. Die Mikro- Zertifikate werden auf einer weltweiten Börse gehandelt; ihr Preis ergibt sich aus Angebot und Nachfrage. Das Geld, das durch die Versteigerung der Mikro-Zertifikate zusammenkommt, wird in regelmäßigen Abständen und ohne Abzüge an jeden einzelnen Menschen ausgezahlt. Das ist einfach, fair und transparent. In einem zweiten Schritt sind die weltweiten CO2-Emissionen drastisch zu verringern, und zwar sieben Jahre lang um jeweils 10%. (shrink)

In its reaction on the terroristic attacks of September 9th, 2001, the US-government threatened Afghanistan's Taleban with war in order to force them to extradite terrorist leader Bin Laden; the Taleban said that they would not surrender to this kind of blackmail – and so, they were removed from Kabul by means of military force. The rivalling versions of this story depend crucially on notions such as "terrorism" and "blackmail". Obviously you'll gain public support for your preferrend version of the (...) story if you are able to determine how those notions are to be used. So we had better reflect about their very meaning and about the moral implications of their proper usage. To gain a deeper understanding of our notions of "blackmail" and "terrorism" I shall propose an extreme thought experiment: Cassandra's plan. Cassandra foresees that sooner or later one of the nuclear powers might take the liberty to use atomic bombs. From fright she founds an NGO for blackmailing the statesmen who are in charge of nuclear weapons; she announces in public that all ministers and leaders of any government shall be hunted down, and executed, whose soldiers drop but one atomic bomb. (Cassandra's NGO keeps killer teams in constant training so as to increase the effect of the threat; this is being financiated from private donations). In my paper I shall raise two questions (without claiming to provide definite answers). First, would we have to say that Cassandra's NGO was a terrorist organisation? Second, would it be morally wrong if Cassandra blackmailed statesmen in the way indicated? (shrink)

We use quotation marks when we wish to refer to an expression. We can and do so refer even when this expression is composed of characters that do not occur in our alphabet. That's why Tarski, Quine, and Geach's theories of quotation don't work. The proposals of Davidson, Frege, and C. Washington, however, do not provide a plausible account of quotation either. (Section I). The problem is to construct a Tarskian theory of truth for an object language that contains quotation (...) marks, without appealing to quotation marks in the metalanguage. I propose to supply Tarski's truth definition with one axiom that determines the denotation of all expressions containing quotation marks. According to this axiom, quotation marks create a non-extensional context. Since admitting such contexts does not lead to any difficulties in the recursive truth characterization, we may indeed dispense with extensionalism. (Section II). Finally, I argue that we classify and denote expressions in the very same way that we classify and denote extralinguistic entities. Both tokens and types of written signs can be easily incorporated into the naturalist's worldview. (Section III). (shrink)

When it became uncool to speak of beauty with respect to pieces of art, physicists started claiming that their results are beautiful. They say, for example, that a theory's beauty speaks in favour of its truth, and that they strive to perform beautiful experiments. What does that mean? The notion cannot be defined. (It cannot be defined in the arts either). Therefore, I elucidate it with examples of optical experimentation. Desaguliers' white synthesis, for example, is more beautiful than Newton's, and (...) the many colourful syntheses done by Viennese painter Ingo Nussbaumer exemplify even greater beauty. Here are some criteria (which, of course, do not implement a decision procedure concerning beauty in experiments): cleanliness, simplicity, intellectual clarity, symmetry. Similar criteria are relevant to our aesthetical judgements about some pieces of music. So we can assume that our notion of beauty conserning art is related to the one conserning scientific experiments. (shrink)

Can we conceive of a mind without body? Does, for example, the idea of the soul's immortality make sense? Certain versions of materialism deny such questions; I shall try to prove that these versions of materialism cannot be right. They fail because they cannot account for the mental vocabulary from the language of brains in the vat. Envatted expressions such as "I think", "I believe", etc., do not have to be reinterpreted when we translate them to our language; they are (...) semantically stable. By contrast, physical expressions from the vat language are semantically instable; due to Putnam's externalism they cannot be transported to our language without change. This contrast opens the way to a new understanding of what the immortality of the soul might be like: A brain in a vat (and its mental life) might survive what the brain calls "my physical body's death".

The analytic/synthetic distinction can be conceived from two points of view: from within or from without; from the perspective of one's own language or from the perspective of the language of others. From without, the central question is which sentences of a foreign language are to be classified as analytic. From within, by contrast, the question concerning the synthetic and the analytic acquires a normative dimension: which sentences am I not permitted to reject—if I want to avoid talking nonsense? Both (...) perspectives on analytic sentences do not mutually exclude but supplement and illuminate each other. In "Two Dogmas", Quine's criticism of the analytic/synthetic distinction comes from within, whereas in Word and Object, Quine repeats his earlier criticism from without. His criticism is directed against Carnap's views on our understanding of theoretical terms. I challenge Quine's criticism in both of its versions and provide two definitions for analyticity that are immune to Quine's arguments. Using the first of these definitions (the one from without) I try to show how it is possible to distinguish (genuine) belief revision from linguistic change—even in case of a scientific revolution.

In this paper, I describe some strategies for teaching an introductory philosophy of science course to Science, Technology, Engineering, and Mathematics (STEM) students, with reference to my own experience teaching a philosophy of science course in the Fall of 2020. The most important strategy that I advocate is what I call the “Second Philosophy” approach, according to which instructors ought to emphasize that the problems that concern philosophers of science are not manufactured and imposed by philosophers from the outside, but (...) rather are ones that arise internally, during the practice of science itself. To justify this approach, I appeal to considerations from both educational research and the epistemology of testimony. In addition, I defend some distinctive learning goals that philosophy of science instructors ought to adopt when teaching STEM students, which include rectifying empirically well-documented shortcomings in students’ conceptions of the “scientific method” and the “nature of science.” Although my primary focus will be on teaching philosophy of science to STEM students, much of what I propose can be applied to non-philosophy majors generally. Ultimately, as I argue, a successful philosophy of science course for non-philosophy majors must be one that advances a student’s science education. The strategies that I describe and defend here are aimed at precisely that end. (shrink)

Pacifists and their opponents disagree not only about moral questions, but most often about factual questions as well. For example, they came to divergent descriptions of the crisis in Kosovo. According to my reconstruction of pacifism, this is not a surprise because the pacifist, legitimately, looks at the facts in the light of her system of value. Her opponent, in turn, looks at the facts in the light of alternative systems of value, and the quarrel between the two parties about (...) supposedly descriptive matters does not come to an end as there is no objective reality about the war in question that could settle the issue. If I am right, the pacifist's value-laden way of looking at reality can be reconstructed as an obedience to three epistemic imperatives. First, the Epistemic Imperative concerning Human Nature ("Resist against demonizing the other side; always try to understand the case from their point of view"). Second, the Epistemic Imperative concerning Non-Violent Alternatives ("Always search for non-violent alternatives to projected military action"). Third, the Epistemic Imperative concerning Uncontrolled Escalation ("Sharpen your attention for uncontrolled, irreversible side effects of military action, particularly for the danger of escalation to another world war"). Objective reality does not decide how far one should go in following these imperatives. Rather, the decision about this is our's—similarly as in case of the scientist who decides to search for common deep structure behind the chaos of the manifold. So the pacifist's epistemic imperatives can be compared to Kant's regulative principles that are necessary for guiding the scientific scrutiny of reality. (shrink)
