One of metaepistemology’s most central debates revolves around the question of what the source of epistemic normativity is. Epistemic instrumentalism claims that epistemic normativity is a species of means-ends normativity. One of the most prominent objections against epistemic instrumentalism features cases of epistemic indifference: Cases where there’s evidence that p yet believing that p wouldn’t promote any of the agent’s aims, wants, or needs. Still, there’s an epistemic reason for the agent to believe that p and thus epistemic instrumentalism is (...) false. In response, instrumentalists have modified their views in various ways, with new contributions still forthcoming. Here, we investigate a neglected aspect of this debate: Laypeople’s judgments on cases of epistemic indifference. In two studies, we investigated whether laypeople agree with the verdict in cases of epistemic indifference as well as the key ideas behind the more recent instrumentalist replies. Our findings indicate that a significant amount of participants found it hard to “buy into” the cases of epistemic indifference as Kelly has constructed them. Participants did generally share Kelly’s judgment in cases of epistemic indifference. Lastly, some instrumentalist replies are well suited to explain participants’ judgments that agents ought to believe in cases of epistemic indifference. (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)

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)

According to a well-known view in the philosophy of mind, intentional attitudes by their very nature satisfy requirements of rationality (e.g. Davidson 1980; Dennett 1987; Millar 2004). This view (which I shall call Constitutivism) features prominently as the ‘principle of minimal rationality’ in de Sousa’s monograph The Rationality of Emotion (1987). By explicating this principle in terms of the notion of the formal object of an attitude, de Sousa articulates an interesting and original version of Constitutivism, which differs in important (...) respects from other extant versions. In this paper, I explore this version of Constitutivism against the background of recent developments in the theory of rationality and make explicit its ramifications for the long-standing dispute over whether the mind is essentially normative. My focus will be on how to conceive of the form of the rationality requirements that attitudes as such must satisfy according to this principle. I argue that, although de Sousa seems officially to endorse a structuralist conception of rationality, according to which these requirements are requirements of coherence, his considerations on formal objects suggest that they are more aptly conceived in terms of a reasons-responsive conception of rationality. I further argue that which of these two readings we choose makes a significant difference to the prospect of vindicating the essential normativity of mind by invoking the principle of minimal rationality.

There is, in some quarters, concern about high–level machine intelligence and superintelligent AI coming up in a few decades, bringing with it significant risks for humanity. In other quarters, these issues are ignored or considered science fiction. We wanted to clarify what the distribution of opinions actually is, what probability the best experts currently assign to high–level machine intelligence coming up within a particular time–frame, which risks they see with that development, and how fast they see these developing. We thus (...) designed a brief questionnaire and distributed it to four groups of experts in 2012/2013. The median estimate of respondents was for a one in two chance that high-level machine intelligence will be developed around 2040-2050, rising to a nine in ten chance by 2075. Experts expect that systems will move on to superintelligence in less than 30 years thereafter. They estimate the chance is about one in three that this development turns out to be ‘bad’ or ‘extremely bad’ for humanity. (shrink)

Are we perhaps in the "matrix", or anyway, victims of perfect and permanent computer simulation? No. The most convincing—and shortest—version of Putnam's argument against the possibility of our eternal envattment is due to Crispin Wright (1994). It avoids most of the misunderstandings that have been elicited by Putnam's original presentation of the argument in "Reason, Truth and History" (1981). But it is still open to the charge of question-begging. True enough, the premisses of the argument (disquotation and externalism) can be (...) formulated and defended without presupposing external objects whose existence appears doubtful in the light of the very skeptical scenario which Putnam wants to repudiate. However, the argument is only valid if we add an extra premiss as to the existence of some external objects. In order to avoid circularity, we should run the argument with external objects which must exist even if we are brains in a vat, e.g. with computers rather than with trees. As long as the skeptic is engaged in a discussion of the brain-in-a-vat scenario, she should neither deny the existence of computers nor the existence of causal relations; for if she does, she is in fact denying that we are brains in a vat.

While it is often said that robotics should aspire to reproducible and measurable results that allow benchmarking, I argue that a focus on benchmarking can be a hindrance for progress in robotics. The reason is what I call the ‘measure-target confusion’, the confusion between a measure of progress and the target of progress. Progress on a benchmark (the measure) is not identical to scientific or technological progress (the target). In the past, several academic disciplines have been led into pursuing only (...) reproducible and measurable ‘scientific’ results – robotics should be careful to follow that line because results that can be benchmarked must be specific and context-dependent, but robotics targets whole complex systems for a broad variety of contexts. While it is extremely valuable to improve benchmarks to reduce the distance be- tween measure and target, the general problem to measure progress towards more intelligent machines (the target) will not be solved by benchmarks alone; we need a balanced approach with sophisticated benchmarks, plus real-life testing, plus qualitative judgment.

In der Literatur zur Wirkungsgeschichte der Farbenlehre Goethes aus dem Jahr 1810 grassieren zwei Vorurteile: (1) Nur ein einziger Physiker von Rang (Seebeck) habe sich auf Goethes Projekt wissenschaftlich eingelassen. (2) Schon zu Goethes Lebzeiten habe sich die Fachwissenschaft mit überwältigender Mehrheit gegen den Dichter ausgesprochen. Beide Behauptungen sind falsch. ad (1): Der bedeutende Physiker und Chemiker Johann Ritter hat zwischen 1800 und 1801 eng mit Goethe kooperiert, dieselbe Forschungsmethode eingesetzt wie Goethe und aufgrund dieser Kooperation das UV-Licht entdeckt. Bis (...) zu seinem Lebensende war er der Ansicht, dass die newtonische Theorie durch Fortführung der Experimente Goethes unterminiert werden könne. ad (2): Wie sich bei einer Kampfabstimmung unter den MINT-Forschern der Goethe-Zeit ergibt (bei der sämtliche veröffentlichte Voten von 1810 bis 1832 gezählt werden), stimmten gegen Goethe die Hälfte der Naturwissenschaftler, für ihn ein Drittel, bei 15 Prozent Stimmenthaltungen. Goethe hat die Abstimmung in der Tat verloren, doch eine verheerende Niederlage sähe anders aus. (shrink)

Goethes Protest gegen Newtons Theorie des Lichts und der Farben ist besser, als man gemeinhin denkt. Man kann diesem Protest in den wichtigsten Elementen folgen, ohne Newton in der physikalischen Sache unrecht zu geben. Laut meiner Interpretation hat Goethe in Newtons wissenschaftsphilosophischer Selbsteinschätzung eine entscheidende Schwäche aufgedeckt: Newton glaubte, mithilfe prismatischer Experimente beweisen zu können, dass das Licht der Sonne aus Lichtstrahlen verschiedener Farben zusammengesetzt sei. Goethe zeigt, dass dieser Übergang vom Beobachtbaren zur Theorie problematischer ist, als Newton wahrhaben wollte. (...) Wenn Goethe darauf beharrt, dass uns der Übergang zur Theorie nicht von den Phänomenen aufgezwungen wird, dann kommt dadurch unser eigener, freier und kreativer Beitrag zur Theorie-Bildung ans Tageslicht. Und diese Einsicht Goethes gewinnt eine überraschende Schärfe, weil Goethe plausibel machen kann, dass sich alle entscheidenden prismatischen Experimente Newtons ebenso gut mit einer alternativen Theorie vereinbaren lassen. Wenn ich recht sehe, war Goethe der erste Wissenschaftsphilosoph, der mindestens eine empirisch äquivalente Alternative zu einer wohletablierten physikalischen Theorie gesehen hat: Damit war Goethe seiner Zeit um ein gutes Jahrhundert voraus.

Die Frage des Weiterlebens nach dem Tod ist sinnvoll, selbst im Lichte des strengen Sinnkriteriums der logischen Empiristen. Schlick schlägt folgende Verifikationsmethode fürs postmortale Weiterleben vor: "Warte, bis Du stirbst". Da Schlick diesen Gedanken nicht ausgearbeitet hat, spiele ich verschiedene Versionen der vorgeschlagenen Verifikation durch: Weiterleben mit einem fremden Körper und körperloses Weiterleben. Um die Identität des Weiterlebenden zu sichern, braucht der Weiterlebende Erinnerungen, intellektuelle Aktivität, Willensentscheidungen und kontinuierliche Erlebnisse ohne Bruch. Ob diese Aspekte unseres mentalen Lebens allesamt für Schlicks (...) Zwecke erforderlich sind, werde ich nicht entscheiden; doch Schlicks Chancen steigen, je mehr Aspekte des mentalen Lebens auch nach dem körperlichen Tod im Spiel bleiben – sicher ist sicher.

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 und keiner übervorteilt werden darf? 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. Anders als die Bundeskanzlerin, die den Grundsatz nur langfristig in die Tat umsetzen will, plädiere ich dafür, dass die Gleichberechtigung (...) aller in Sachen CO2-Ausstoß schon unter dem Nachfolge-Regime des Kyoto-Vertrags gelten soll. 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. Mein Vorschlag unterscheidet sich in zweierlei Hinsicht von den Versteigerungen der CO2-Zertifikate, wie sie bislang konzipiert und organisiert worden sind. Einerseits sollen am Ende alle Emissionen klimaschädlicher Gase in den Handel mit Mikro-Zertifikaten einbezogen werden. Andererseits wird das Geld, das durch die Versteigerung der Mikro-Zertifikate zusammenkommt, 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: Nach einer siebenjährigen Verschnaufpause (in der sich Produzenten und Verbraucher auf die erforderlichen Anpassungen vorbereiten können) beginnen die sieben dürren Jahre der CO2-Politik: Jahr für Jahr werden 10% weniger Mikro-Zertifikate ausgegeben. Am Ende dieser Durststrecke haben sich die weltweiten CO2-Emissionen halbiert, und die Klima-Investitionen sind dahin geflossen, wo sie dem Klima am stärksten nutzen und wo das am wenigsten Kapital verschlingt.

Als Goethe in seiner monumentalen Farbenlehre einen Angriff auf Newtons Theorie des Lichts und der Farben lancierte, 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). Kürzlich hat der Wiener Maler Ingo Nussbaumer (...) 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 bunter 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. Und sie tauchen die überkommenen Prinzipien der additiven und der subtraktiven Farbmischung in neues Licht. (shrink)

Wie sich aus Newtons eigener Theorie ableiten lässt, hat jedes Experiment, das Newton zugunsten seiner Theorie anführen kann, ein umgedrehtes Gegenstück, worin die Rollen von Licht und Dunkel genau vertauscht sind und jede bunte Farbe durch ihre Komplementärfarbe ersetzt ist. Daraus ergeben sich weitreichende wissenschaftsphilosophische Konsequenzen: Mit Newtons eigener Logik kann man aus den umgekehrten Experimenten auch eine umgekehrte Theorie beweisen: die Theorie von der Heterogenität der Finsternis. Laut dieser Theorie besteht Finsternis aus verschiedenfarbigen Schattenstrahlen, während das Helle als Abwesenheit optischer Kausalfaktoren gedeutet wird (so wie bei Newton die Dunkelheit). Diese neue Theorie bietet ein hervorragendes neues Beispiel für Quines These von der Unterbestimmtheit der Theorie durch Daten und Theorietugenden. Und in der Tat war Goethe wohl der erste Verfechte einer Unterbestimmtheitsthese. (shrink)

The perhaps most challenging problem for a panentheistic paradigm in Christian god-talk consists in integrating the trait of personhood in the monistic horizon of this approach. A very helpful way to this goal seems to be the concept of imagination. Its logic of an “as if” represents a modified variation of Kant`s idea of the postulates of reason. Reflections of Jürgen Werbick, Douglas Headley, and Volker Gerhardt substantiate the philosophical and theological capabilities of this solution which also include a sensibility (...) for the ontological commitments included in the panentheistic approach.

Will future lethal autonomous weapon systems (LAWS), or ‘killer robots’, be a threat to humanity? The European Parliament has called for a moratorium or ban of LAWS; the ‘Contracting Parties to the Geneva Convention at the United Nations’ are presently discussing such a ban, which is supported by the great majority of writers and campaigners on the issue. However, the main arguments in favour of a ban are unsound. LAWS do not support extrajudicial killings, they do not take responsibility away (...) from humans; in fact they increase the abil-ity to hold humans accountable for war crimes. Using LAWS in war would probably reduce human suffering overall. Finally, the availability of LAWS would probably not increase the probability of war or other lethal conflict—especially as compared to extant remote-controlled weapons. The widespread fear of killer robots is unfounded: They are probably good news. (shrink)

While the 2010 EPSRC principles for robotics state a set of 5 rules of what ‘should’ be done, I argue they should differentiate between legal obligations and ethical demands. Only if we make this difference can we state clearly what the legal obligations already are, and what additional ethical demands we want to make. I provide suggestions how to revise the rules in this light and how to make them more structured.

Anders als oft behauptet wird, hat Goethe in seinen optischen Experimenten sehr präzise nachgemessen. So stellt seine fünfte Tafel eine ganze experimentelle Serie geometrisch akkurat dar, und zwar in einem cartesischen Koordinaten-System, dessen Maßstab sich recht genau rekontruieren lässt. Indem Goethe seine Versuchsergebnisse idealisierte und von störenden Nebeneffekten bereinigte, folgte er einer gängigen Praxis damaliger und heutiger Naturwissenschaft. Er idealisierte anders als Newton, verstieß dadurch aber nicht gegen die Regeln der Experimentierkunst.

Moritz Schlicks Plädoyer für ein empirisches Fundament unserer Erkenntnis enthält weder reduktionistische noch phänomenalistische Extrempositionen. Seine Beispiele für Fundamentalsätze haben allesamt die Form: Hier jetzt so und so; aber nicht alle diese Sätze sind Fundamentalsätze.

Demzufolge sind diejenigen Sätze (der Form Hier jetzt so und so) Fundamentalsätze, über die kein (...) inhaltlicher Streit aufkommen kann; wer bei solchen Sätzen – unter denselben Umständen – zu einem anderen Urteil kommt als wir, der bezeugt dadurch keine Meinungsverschiedenheit in der Sache, sondern nur einen anderen Gebrauch sprachlicher Ausdrücke.

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.

Nachdem Ritter am 22.2.1801 die UV-Strahlen entdeckt hatte, besuchte er Goethe und machte mit ihm am Vormittag des 25.2.1801 optische Versuche; vermutlich hat er ihm sein bahnbrechendes Experiment zum UV-Licht gezeigt. Die räumlichen Gegebenheiten in Goethes Arbeitszimmer legen einen Versuchsaufbau nahe, der sich gut rekonstruieren lässt: Das Sonnenlicht wurde zwischen 12 und 13 Uhr durch ein Loch im linken Fensterladen seines Arbeitszimmers und durch eine durchlöcherte Pappschablone auf Goethes großes Wasserprisma geleitet und anderthalb Meter weiter hinten in Form eines newtonischen (...)

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.

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)

The contribution of the body to cognition and control in natural and artificial agents is increasingly described as “off-loading computation from the brain to the body”, where the body is said to perform “morphological computation”. Our investigation of four characteristic cases of morphological computation in animals and robots shows that the ‘off-loading’ perspective is misleading. Actually, the contribution of body morphology to cognition and control is rarely computational, in any useful sense of the word. We thus distinguish (1) morphology that (...) facilitates control, (2) morphology that facilitates perception and the rare cases of (3) morphological computation proper, such as ‘reservoir computing.’ where the body is actually used for computation. This result contributes to the understanding of the relation between embodiment and computation: The question for robot design and cognitive science is not whether computation is offloaded to the body, but to what extent the body facilitates cognition and control – how it contributes to the overall ‘orchestration’ of intelligent behaviour.

Artificial intelligence (AI) and robotics are digital technologies that will have significant impact on the development of humanity in the near future. They have raised fundamental questions about what we should do with these systems, what the systems themselves should do, what risks they involve, and how we can control these. - After the Introduction to the field (§1), the main themes (§2) of this article are: Ethical issues that arise with AI systems as objects, i.e., tools made and used (...) by humans. This includes issues of privacy (§2.1) and manipulation (§2.2), opacity (§2.3) and bias (§2.4), human-robot interaction (§2.5), employment (§2.6), and the effects of autonomy (§2.7). Then AI systems as subjects, i.e., ethics for the AI systems themselves in machine ethics (§2.8) and artificial moral agency (§2.9). Finally, the problem of a possible future AI superintelligence leading to a “singularity” (§2.10). We close with a remark on the vision of AI (§3). - For each section within these themes, we provide a general explanation of the ethical issues, outline existing positions and arguments, then analyse how these play out with current technologies and finally, what policy consequences may be drawn.

In this paper, I argue that the widely held view that Aristotle's vicious agent is a principled follower of a wrong conception of the good whose soul, just like the soul of the virtuous agent, is marked by harmony between his reason and non-rational desires is an exegetical mistake.

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)

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)

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)

The philosophy of AI has seen some changes, in particular: 1) AI moves away from cognitive science, and 2) the long term risks of AI now appear to be a worthy concern. In this context, the classical central concerns – such as the relation of cognition and computation, embodiment, intelligence & rationality, and information – will regain urgency.

Let us imagine an ideal ethical agent, i.e., an agent who (i) holds a certain ethical theory, (ii) has all factual knowledge needed for determining which action among those open to her is right and which is wrong, according to her theory, and who (iii) is ideally motivated to really do whatever her ethical theory demands her to do. If we grant that the notions of omniscience and ideal motivation both make sense, we may ask: Could there possibly be an (...) ideal utilitarian, that is, an ideal ethical agent whose ethical theory says that our only moral obligation consists in maximizing utility? I claim that an ideal agent cannot be utilitarian. My reasoning against ideal utilitarianism will parallel Putnam's famous argument against the brains in a vat. Putnam argues that an envatted brain cannot describe its own situation because its words do not refer to brains and vats; I argue that an ideal utilitarian cannot entertain or communicate the beliefs necessary to being a utilitarian.

"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. After a certain ordering of the landscape, I argue that we need to add the category of "dangerous" information and that this category has gained a new quality in the context of current information technology, specifically the Internet. 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)

Quine's early arguments in favor of "Ontological Relativity" depend on wild but interesting alternatives to standard ontology,most apparent when viewing his unusual idea of undetached object parts. In Quine's later philosophy, by contrast, he invokes trivial proxy functions and simple permutations to standard ontology, and in so doing paves the way for his claim of "Inscrutability of Reference". Nevertheless, Quine's more recent alternatives to standard ontology have thus far remained uninteresting for ontological questions, as his later arguments fail to offer (...) any real alternative to our standard identity relation. For this reason, I have chosen to return to Quine's original idea of "Ontological Relativity" and put it to the test. In my investigation, development and subsequent defense of Quine's original presentation, I attempt to show that it is in fact possible to read Quine's ontology of undetached object parts into a large sphere of our language.

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)

The paper defends three claims about Aristotle’s theory of uncontrolled actions (akrasia) in NE 7.3. First, I argue that the first part of NE 7.3 contains the description of the overall state of mind of the agent while she acts without control. Aristotle’s solution to the problem of uncontrolled action lies in the analogy between the uncontrolled agent and people who are drunk, mad, or asleep. This analogy is interpreted as meaning that the uncontrolled agent, while acting without control, is (...) still in possession of her knowledge but she is unable to use it as knowledge due to the temporary disablement of her reason by appetite. Due to this disablement, the uncontrolled agent is temporarily unable to be motivated to act by her knowledge and acts merely on her appetite. Second, I argue that the second part of NE 7.3 provides an analysis of the particular mental state from which the uncontrolled action issues. Its central passage is a description of the uncontrolled agent’s state of mind before the uncontrolled action and not, as it has been traditionally understood, a description of her state of mind during the uncontrolled action. Third, I argue that, on Aristotle’s view, the transition from the state before the uncontrolled action to the state in which the agent already acts without control does not involve any psychological state that would constitute the agent’s choice to abandon her decision and give in to her desires but proceeds on a purely physiological level.

I defend two main theses. First, I argue that Aristotle’s account of voluntary action focuses on the conditions under which one is the cause of one’s actions in virtue of being (qua) the individual one is. Aristotle contrasts voluntary action not only with involuntary action but also with cases in which one acts (or does something) due to one’s nature (for example, in virtue of being a member of a certain species) rather than due to one’s own desires (i.e. qua (...) individual). An action can be attributed to one qua individual in two distinct ways depending on whether one is a rational or a non-rational animal. One is responsible for one’s action in both cases, but only in the former case is one also responsible for being the sort of individual that performs it. Aristotle also distinguishes two ways in which an action can be compelled while still being an action of the agent. In the first case, one is compelled by (physically) external forces or circumstances to act against one’s internal impulse. In the second case, one is compelled to act on (internal) impulses that are fixed by one’s nature against one’s own individual impulse. This latter kind of compelled action is only possible in the case of rational agents. Secondly, I argue that Aristotle’s conception of what it is to be a cause of an action inevitably brings in certain normative features which support evaluative judgments and the practice of praise and blame. On Aristotle’s view, any goal-directed behavior that is properly attributable to an individual is (normally) subject to standards that pertain to behavior of that sort. At the most basic level, these standards establish what counts as a successful realization of the goal that one aims at. Thus even in the case of non-rational animals (or children), one can judge the success of what they are doing and encourage (or discourage) similar behavior by praise or blame. These standards are applicable to one’s conduct simply insofar as one is the controlling origin (or efficient cause) of one’s action qua individual. In the case of rational agents the practice of praise and blame can involve a further normative layer since they can be praised or blamed not only for acting in a certain way so as to encourage or discourage them with a view to the future, but also for being – and having become – individuals of a certain sort. Nevertheless, the applicability of such evaluative judgments and of praise and blame is still warranted by one’s being the controlling origin of one’s actions qua the individual one is (in this case, qua rational individual).

In this paper I want to propose an argument to support Jerry Fodor’s thesis (Fodor 1983) that input systems are modular and thus informationally encapsulated. The argument starts with the suggestion that there is a “grounding problem” in perception, i. e. that there is a problem in explaining how perception that can yield a visual experience is possible, how sensation can become meaningful perception of something for the subject. Given that visual experience is actually possible, this invites a transcendental argument (...) that explains the conditions of its possibility. I propose that one of these conditions is the existence of a visual module in Fodor’s sense that allows the step from sensation to object-identifying perception, thus enabling visual experience. It seems to follow that there is informationally encapsulated nonconceptual content in visual perception. (shrink)

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.

This paper is a philosophical discussion about the link between utopianism and responsibility. It argues that our time demands a strong practice of political responsibility in both organizations and society based on what has been called ‘real utopianism’. It takes as a starting point Hans Jonas’ critique of utopianism. Keeping in mind the horrors of the Second World War this Jewish thinker disconnected the principle of responsibility from the idea of utopianism, and connected it to a ‘heuristics of fear’ – (...) we should be careful with ‘wild’ new technologies, but also with new utopian perspectives. In a second step Jonas’ predecessors and utopian thinkers Martin Buber, Ernst Bloch and Ernest Callenbach are revisited. They show that a fully conceptualized idea of utopianism includes at least three dimensions of responsibility: subsistence, justice and spirituality. I then argue that if one digs deeper into the work of Jonas, it seems that the concept of responsibility in fact implies the courage to overcome a heuristics of fear. This paper therefore argues that there is no need to radically disjunct responsibility from utopianism and that the concept of responsibility actually opens a path to ‘real utopianism’. Such a concept of responsibility can best be supported by a confessionally neutral but nonetheless spiritual eco-humanist worldview that develops a new attitude towards nature, in which (eco)asceticism, morality and spirituality become intertwined.

At the beginning of the twentieth century, Christianity was predominantly a white Euro- American religion with 83 per cent of all Christians living in the Global North. Today, it is a global religion where over two-thirds of Christians are non-Westerners residing in the Global South. Christianity is on the rise in Latin America, Asia and especially Africa: a trend that is predicted to continue in the second half of the twenty-first century. I will explore explanations for the appeal of Christianity, (...) and Pentecostalism in particular, for contemporary Africans. (shrink)

The theory that all processes in the universe are computational is attractive in its promise to provide an understandable theory of everything. I want to suggest here that this pancomputationalism is not sufficiently clear on which problem it is trying to solve, and how. I propose two interpretations of pancomputationalism as a theory: I) the world is a computer and II) the world can be described as a computer. The first implies a thesis of supervenience of the physical over computation (...) and is thus reduced ad absurdum. The second is underdetermined by the world, and thus equally unsuccessful as theory. Finally, I suggest that pancomputationalism as metaphor can be useful. – At the Paderborn workshop in 2008, this paper was presented as a commentary to the relevant paper by Gordana Dodig-Crnkovic " Info-Computationalism and Philosophical Aspects of Research in Information Sciences".

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.

Some authors have recently suggested that it is time to consider rights for robots. These suggestions are based on the claim that the question of robot rights should not depend on a standard set of conditions for ‘moral status’; but instead, the question is to be framed in a new way, by rejecting the is/ought distinction, making a relational turn, or assuming a methodological behaviourism. We try to clarify these suggestions and to show their highly problematic consequences. While we find (...) the suggestions ultimately unmotivated, the discussion shows that our epistemic condition with respect to the moral status of others does raise problems, and that the human tendency to empathise with things that do not have moral status should be taken seriously—we suggest that it produces a “derived moral status”. Finally, it turns out that there is typically no individual in real AI that could even be said to be the bearer of moral status. Overall, there is no reason to think that robot rights are an issue now. (shrink)
