In this book I examine various forms of indeterminacy in the law and scrutinize (i.a. by way of game theoretical models) the conditions under which they can be strategically used. In particular, I analyze the advantages and disadvantages of indeterminacy in the wording of laws, contracts, and verdicts. Legal texts are particularly interesting insofar as they address a heterogeneous audience, are applied in a variety of unforeseeable circumstances and must, at the same time, lay down clear and unambiguous standards. I (...) argue for the claim that semantic vagueness is less relevant than commonly supposed in the debate, while other forms of indeterminacy (in particular, polysemy and standard-relativity) are underrated or altogether ignored. This misconception is, as I argue, due to a systematic confusion between semantic vagueness and these forms of indeterminacy. Once it is resolved, the value of indeterminacy can be clearly shown.

Classically, vagueness has been considered something bad. It leads to the Sorites paradox, borderline cases, and the (apparent) violation of the logical principle of bivalence. Nevertheless, there have always been scholars claiming that vagueness is also valuable. Many have pointed out that we could not communicate as successfully or efficiently as we do if we would not use vague language. Indeed, we often use vague terms when we could have used more precise ones instead. Many scholars (implicitly or explicitly) assume (...) that we do so because their vagueness has a positive function. But how and in what sense can vagueness be said to have a function or value? This paper is an attempt to give an answer to this question. After clarifying the concepts of vagueness and value, it examines nine arguments for the value of vagueness, which have been discussed in the literature. The (negative) result of this examination is, however, that there is not much reason to believe that vagueness has a value or positive function at all because none of the arguments is conclusive. A tenth argument that has not been discussed so far seems most promising but rests on a solely strategic notion of function. (shrink)

Mit großer Wahrscheinlichkeit wird die Alternative für Deutschland (AfD) am 24. September in den Bundestag einziehen. Jüngste Umfragen legen nahe, dass sie sogar drittstärkste Partei werden könnte. Warum findet die AfD so viele Unterstützerinnen und Unterstützer? Mit welchen Argumenten wirbt die AfD für ihren Einzug in den Bundestag? Das Wahlprogramm der AfD zeigt nicht nur, wofür die Partei steht, sondern auch welche Strategie sie bei der Bundestagswahl und darüber hinaus verfolgt. Aus diesem Grund habe ich es argumentationstheoretisch analysiert und die (...) darin enthaltene Argumentation im Detail rekonstruiert. Die wichtigsten Ergebnisse umfassen: Erstens, aus einer rein logischen Perspektive ist die Argumentation der AfD außergewöhnlich klar und stringent. Dies gelingt ihr deshalb, weil sie sich gezielt auf Annahmen stützt, die vereinfachend oder konstruiert sind. Zweitens, das zentrale Thema der „Flüchtlingskrise“ zieht sich beinahe durch die gesamte Argumentation. Es taucht in Argumenten über den Verlust der Leitkultur oder den Verfall der inneren Sicherheit genauso auf wie in Argumenten über die Folgen der Globalisierung oder den demographischen Wandel. Drittens, und dies ist das zentrale Ergebnis der Analyse, die AfD argumentiert nach dem folgenden Muster: Es gibt eine Bedrohung. Nur die AfD kann uns davor bewahren. Also muss die AfD an die Macht kommen. Dies nenne ich das „Kernargument des Populismus“. (shrink)

Das aktuelle politische Zeitgeschehen offenbart zunehmend ein Phänomen, das in der philosophischen Fachliteratur als „Bullshit“ bezeichnet wird. Im Unterschied zum Lügner, der über die Fakten täuschen will, stellt der Bullshitter seine Behauptungen ohne jedwede Orientierung an der Wahrheitsfindung auf. Wir unterscheiden verschiedene Arten von Bullshit und führen das Konzept des demonstrativen Bullshits ein. Wie wir zeigen, hat demonstrativer Bullshit im politischen Diskurs besondere Sprengkraft. Bullshitten politische Akteure demonstrativ, untergraben sie damit die Norm der Wahrheit im gesellschaftlichen Diskurs und tragen auf (...) diese Weise dazu bei, die Grundlage für demokratische Meinungsbildungs- und Entscheidungsprozesse zu zersetzen. Wir zeigen, dass die Digitalisierung die Verbreitung und Akzeptanz demonstrativen Bullshits in der Tendenz begünstigt, und skizzieren, auf welche Weise politische Bildung diesen Entwicklungen entgegenwirken kann.

Recently, the term «fake news» has become ubiquitous in political and public discourse and the media. Despite its omnipresence, however, it is anything but clear what fake news is. An adequate and comprehensive definition of fake news is called for. We take steps towards this goal by providing a systematic account of fake news that makes the phenomenon tangible, rehabilitates the use of the term, and helps us to set fake news apart from related phenomena. (You can email us for (...) a penultimate draft of this paper.). (shrink)

Heute gibt es kaum jemanden mehr, der nicht mit Fake News und Verschwörungstheorien in Berührung gekommen wäre. Mit dem globalen Aufstieg des modernen Populismus und besonders seit Donald Trumps US-Präsidentschaft konnten sie von obskuren Internetfo-ren und dem Rand der Gesellschaft weiter als je zuvor in die öffentliche Debatte vordringen. Mit der zunehmenden Nutzung sozialer Medien und Messenger-Apps wie Telegram oder WhatsApp findet scheinbares Wissen ungehindert Verbreitung und direkten Zugang zu den Smartphones und Köpfen der Menschen. Vor diesem Hintergrund ist es (...) nicht verwunderlich, dass Verschwörungstheorien und Fake News auch Einzug ins Klassenzimmer halten. Dabei stehen Lehrer*innen vor vielen offenen Fragen. Wie sind diese Behauptungen im Einzelnen zu bewerten? Was zeichnet Fake News und Verschwörungstheorien aus und was genau macht sie problematisch? Wie, selbst wenn sie klarerweise falsch und unbegründet sind, sollte damit im Klassenzimmer umgegangen werden? Sollte man sie offen diskutieren? Oder sollte man die Diskussion darüber unterbinden? Hier werden grundlegende und komplexe Fragen der freien Meinungsbildung und -äußerung berührt, zu denen Grundgesetz, Beamten- und Schulrecht nur begrenzt Auskunft geben. In diesem Beitrag wollen uns zuerst ein klares Bild davon machen, was Fake News und Verschwörungstheorien eigentlich sind, warum manche Menschen sie für wahr halten und was daran problematisch ist. Vor diesem Hintergrund soll anschließend die Frage diskutiert werden, wie aus demokratie- und bildungstheoretischer Sicht mit Fake News und Verschwörungstheorien im Unterricht umgegangen werden sollte.

Um die Presse- und Meinungsfreiheit wird Tag für Tag gerungen - auch in Deutschland, wo sie im Grundgesetz verankert ist. Was darf man sagen? Wie weit geht die Meinungsfreiheit? Wo endet die Toleranz? Diese Fragen müssen immer wieder auf ein Neues beantwortet werden. Auch in der Demokratie wird die Meinungsfreiheit bedroht. Politscher Populismus und verrohte Kommunikation im Internet stellen das Grundrecht auf die Probe. Rechtsextremisten inszenieren sich als Opfer einer vermeintlichen Meinungsdiktatur, Hasskommentare zerstören die Streitkultur und provozieren neue Gesetze, die (...) im schlechtesten Fall ihrerseits die Meinungsfreiheit aushöhlen. Gut verständlich beschreiben Experten unterschiedlicher Disziplinen die Dimensionen und Herausforderungen der Meinungsfreiheit.

Populism has become one of the most intensely discussed topics in both public debate and academic research. So far there has been no systematic argumentation theoretic analysis of populism, however. This paper is intended to provide first steps towards such an analysis by giving a full argumentation theoretic reconstruction of the political manifesto of the German right-wing populist party “Alternative for Germany” (AfD). This allows to draw preliminary conclusions about the AfD’s argumentative strategy as exemplary for right-wing populism.

When the United States Supreme Court used the expression “with all deliberate speed” in the case Brown v. Board of Education, it did so presumably because of its vagueness. Many jurists, economists, linguists, and philosophers accordingly assume that vagueness can be strategically used to one’s advantage. Roy Sorensen has cast doubt on this assumption by strictly differentiating between vagueness and generality. Indeed, most arguments for the value of vagueness go through only when vagueness is confused with generality. Sorensen claims that (...) vagueness – correctly understood – has no function in law inter alia because judges lie systematically when confronted with borderline cases. I argue that both claims are wrong. First, judges do not need to resort to lying when adjudicating borderline cases, and even if they had to, this would not render vagueness useless. Secondly, vagueness has several important functions in law such as the reduction of decision costs and the delegation of power. Although many functions commonly attributed to the vagueness of legal expressions are in fact due to their generality or other semantic properties, vagueness has at least these two functions in law.

This paper shows why defining „fake news“ is worthwhile and what a suitable definition of “fake news” might look like. We begin by introducing our definition of “fake news” (§2) and employ it to set fake news apart from related phenomena that are often conflated with it (§3). We then extract seven potential dimensions of the concept of fake news from the literature (§4) and compare the most representative definitions that have been proposed so far along those dimensions (§5). In (...) particular, we discuss the definitions by Rini, Gelfert, Dentith, Mukerji, and Zimmermann & Kohring, show up their merits and debits and put them in relation to ours. Although we take our definition as the starting point and argue for it on the side-lines, our primary aims are (i) to enable a systematic evaluation of prevalent definitions with respect to their extensional scope, practical utility, and conceptual transparency, (ii) to demonstrate that there is more widespread agreement than one would think on the outset, and (iii) to show (in §6) that defining “fake news” is not only far from futile, but of vital importance to confront the epistemic threats posed by fake news.

Few philosophers today embrace quantitative hedonism, which states that a person’s well-being depends only on the amount of her experienced happiness and suffering. Despite recent attempts to rehabilitate it, most philosophers still consider it untenable. The most influential arguments levelled against it by Mill, Moore, Nozick and Kagan purport to demonstrate that well-being must depend on more than only the amount of experienced happiness and suffering. I argue in this paper that quantitative hedonism can rebut these arguments by pointing out (...) a shared systematic flaw in their argumentative structure. In particular, I argue that they are based on thought experiments that invoke either structurally unreliable intuitions or intuitions that are not in tension to the tenets of quantitative hedonism. While this does not rehabilitate the theory by itself, it shows that the classical arguments against quantitative hedonism provide far less evidence against it than commonly thought. (shrink)

Drerup (2021) argumentiert dafür, dass Kontroversen im Unterricht eingesetzt werden sollten, um demokratische Grundbildung zu fördern. Als Bildungsziel ist die Förderung demokratischer Grundbildung in seiner Allgemeinheit sicherlich klar zu befürworten, ob der Einsatz von Kontroversen jedoch ein geeignetes und verhältnismäßiges Mittel dafür ist, kann pauschal nicht so leicht beantwortet werden. Schließlich hängt ihre Eignung und Verhältnismäßigkeit ganz maßgeblich davon ab, welche kontroversen Themen im Unterricht auf welche Weise diskutiert werden. Um hier zu einem fruchtbaren Ergebnis zu gelangen, muss zunächst allerdings (...) eine grundlegende Frage beantwortet werden – nämlich, was es überhaupt heißt, konstruktiv zu diskutieren. Dann können nämlich mögliche Funktionen von kontroversen Diskussionen identifiziert und darauf aufbauend sowohl einzelne Ziele, geeignete Themen als auch die jeweiligen Rahmenbedingungen in eine konkrete Beziehung gesetzt werden. So sind die allgemeinen Leitlinien für eine gelingende Praxis, wie Drerup sie formuliert, zwar ausgesprochen hilfreich, aber ob eine Praxis tatsächlich gelingt, kann ohne eine solche Verzahnung zwischen Zielen, Themen und Bedingungen in den meisten Fällen kaum hinreichend geklärt werden. Wenn wir die pädagogisch-didaktischen Ziele jedoch allgemein in der Förderung von individueller und politischer Autonomie und demokratischer Grundbildung sehen, dann müsste man, so die zentrale These des vorliegenden Beitrags, sehr viel mehr zur Qualität von Diskussionen und insbesondere zur Güte von Argumentationen sagen, um dann geeignete Themen und passende Rahmenbedingungen genauer zu bestimmen. Nichtsdestoweniger ist Drerups Band eine enorme Bereicherung für die Debatte. (shrink)

Das Funktionieren moderner Demokratien hängt von der Informiertheit der Öffentlichkeit ab. Durch den Erfolg von Fake News und post-faktischer Politik ist die Informiertheit der Öffentlichkeit jedoch in Gefahr, zumal parallele Öffentlichkeiten zunehmend sogenannte alternative analoge und digitale Medienangebote nutzen. In diesem Beitrag untersuchen wir, wie sich Fake News verbreiten und Einfluss auf Öffentlichkeit und Politik gewinnen. Dazu analysieren wir das Zusammenspiel einer Reihe kognitiver Verzerrungen mit der Funktionsweise sozialer Medien sowie die strukturellen Anreize, die der digitalisierte Medienkapitalismus setzt. Beides spielt (...) der Verbreitung von Fake News in die Hände, was einige politische Akteure auszunutzen wissen. Fake News werden in diesem Fall als Propaganda eingesetzt. Wir unterscheiden vier Funktionen von Fake-News-Propaganda: (1) die Täuschung der Öffentlichkeit, (2) die Stärkung von Gruppenidentitäten, (3) die Demonstration von Macht und (4) die Destabilisierung der politischen oder öffentlichen Ordnung.

Warum gibt es Fake News? Und warum verbreiten sie sich so erfolgreich? Weil der Mensch nicht so rational ist, wie er gerne denkt. Denn Fake News gibt es schon, solange es Nachrichten gibt.

Inhalte werden geteilt, weil man zu einer Gruppe gehören möchte, oder weil sie zu dem passen, was man ohnehin schon glaubt.

Philosophy of science attempts to reconstruct science as a rational cognitive enterprise. In doing so, it depicts a normative ideal of knowledge acquisition and does not primarily seek to describe actual scientific practice in an empirically adequate way. A comprehensive picture of what good science consists in may serve as a standard against which we evaluate and criticize actual scientific practices. Such a normative picture may also explain why it is reasonable for us to trust scientists – to the extent (...) that they live up to the ideal – and to rely on their findings in decision making. Likewise, a sound normative understanding of science exposes the limits of scientific understanding and prevents us from placing blind faith in scientists and experts. For these reasons, philosophy of science represents a useful resource and background theory for the practice and study of science communication. In this handbook article, we provide an opinionated introduction to philosophy of science by flashing a light on 22 central issues which (we think) are of special interest to scholars and practitioners of science communication – and, in particular, to scholars and practitioners of external science communication.

The events of the year 2016 have led many critical observers to doubt the stability and longevity of democracy. Ideally, democracy effectuates the rule of reason. Debates in elected assemblies and in society as a whole should serve the process of finding best reasons for political decisions. However, the mechanisms that currently produce such decisions are vulnerable to misuse. Arguably, they need to be redesigned in an attempt to make them “foolproof” - i.e., to design them in a way to (...) make misuse inherently impossible or to minimize its negative consequences. (shrink)

The recent surge of populism, nationalism and authoritarian tendencies in the political arena as well as the widespread propagation of fake news, conspiracy theories and disinformation in social media are increasingly worrisome and pose a severe threat to democratic societies and the rule of law. Political decisions in such societies must, first and foremost, be guided by evidence and reason. Unfortunately, the events of the last years have shown that the existing institutions and mechanisms are more and more vulnerable to (...) misuse, leaving democracies well and truly adrift from wholesome deliberative practices. It thus seems imperative that those institutions and mechanisms be redesigned in an attempt to make democracy “foolproof” – that is, to provide some sort of immunisation against these threats, even if it is, of course, nearly impossible to achieve such a lofty ideal in practice. This is the second part of a special issue that explores ways to make democracies “foolproof” in the explicated sense. (shrink)

Oxford Philosophical Texts Series Editor: John Cottingham The Oxford Philosophical Texts series consists of authoritative teaching editions of canonical texts in the history of philosophy from the ancient world down to modern times. Each volume provides a clear, well laid out text together with a comprehensive introduction by a leading specialist, giving the student detailed critical guidance on the intellectual context of the work and the structure and philosophical importance of the main arguments. Endnotes are supplied which provide further commentary (...) on the arguments and explain unfamiliar references and terminology, and a full bibliography and index are also included. The series aims to build up a definitive corpus of key texts in the Western philosophical tradition, which will form a reliable and enduring resource for students and teachers alike. David Hume's aim in writing An Enquiry concerning Human Understanding was to introduce his philosophy to a European culture in which many educated people read original works of philosophy. He gives an elegant and accessible presentation of strikingly original and challenging views about the limited powers of human understanding, the attractions of scepticism, the compatibility of free will and determinism, and weaknesses in the foundations of religion. Hume's philosophy was highly controversial in the eighteenth century and remains so today. The text printed in this edition is that of the Clarendon critical edition of Hume's works. A substantial introduction by the editor explains the intellectual background to the work and surveys its main themes. The volume also includes detailed explanatory notes on the text, a glossary of terms, a full list of references, and a section of supplementary readings. (shrink)

This paper aims to provide two abductive considerations adducing in favor of the thesis of Necessitism in modal ontology. I demonstrate how instances of the Barcan formula can be witnessed, when the modal operators are interpreted 'naturally' -- i.e., as including geometric possibilities -- and the quantifiers in the formula range over a domain of natural, or concrete, entities and their contingently non-concrete analogues. I argue that, because there are considerations within physics and metaphysical inquiry which corroborate modal relationalist claims (...) concerning the possible geometric structures of spacetime, and dispositional properties are actual possible entities, the condition of being grounded in the concrete is consistent with the Barcan formula; and thus -- in the geometric setting -- merits adoption by the Necessitist.

Part of the appeal of the biological approach to personal identity is that it does not have to countenance spatially coincident entities. But if the termination thesis is correct and the organism ceases to exist at death, then it appears that the corpse is a dead body that earlier was a living body and distinct from but spatially coincident with the organism. If the organism is identified with the body, then the unwelcome spatial coincidence could perhaps be avoided. It is (...) argued that such an identification would be a mistake. A living organism has a different part/whole relationship and persistence conditions than the alleged body. A case will be made that the concept ‘human body’ is a conceptual mess, vague in an unprincipled manner, and that an eliminativist stance towards dead bodies is the appropriate response.

Various U.S. laws, such as the Clean Air Act and the Food Quality Protection Act, require additional protections for susceptible subpopulations who face greater environmental health risks. The main ethical rationale for providing these protections is to ensure that environmental health risks are distributed fairly. In this article, we (1) consider how several influential theories of justice deal with issues related to the distribution of environmental health risks; (2) show that these theories often fail to provide specific guidance concerning policy (...) choices; and (3) argue that an approach to public decision making known as accountability for reasonableness can complement theories of justice in establishing acceptable environmental health risks for the general population and susceptible subpopulations. Since accountability for reasonableness focuses on the fairness of the decision-making process, not the outcome, it does not guarantee that susceptible subpopulations will receive a maximum level of protection, regardless of costs or other morally relevant considerations.

This book is a defense of modal realism; the thesis that our world is but one of a plurality of worlds, and that the individuals that inhabit our world are only a few out of all the inhabitants of all the worlds. Lewis argues that the philosophical utility of modal realism is a good reason for believing that it is true.

How should one react when one has a belief, but knows that other people—who have roughly the same evidence as one has, and seem roughly as likely to react to it correctly—disagree? This paper argues that the disagreement of other competent inquirers often requires one to be much less confident in one’s opinions than one would otherwise be.

The singularity hypothesis is a radical hypothesis about the future of artificial intelligence on which self-improving artificial agents will quickly become orders of magnitude more intelligent than the average human. Despite the ambitiousness of its claims, the singularity hypothesis has been defended at length by leading philosophers and artificial intelligence researchers. In this paper, I argue that the singularity hypothesis rests on scientifically implausible growth assumptions. I show how leading philosophical defenses of the singularity hypothesis (Chalmers 2010, Bostrom 2014) fail (...) to overcome the case for skepticism. I conclude by drawing out philosophical implications of this discussion for our understanding of consciousness, personal identity, digital minds, existential risk, and ethical longtermism.

What happens when machines become more intelligent than humans? One view is that this event will be followed by an explosion to ever-greater levels of intelligence, as each generation of machines creates more intelligent machines in turn. This intelligence explosion is now often known as the “singularity”. The basic argument here was set out by the statistician I.J. Good in his 1965 article “Speculations Concerning the First Ultraintelligent Machine”: Let an ultraintelligent machine be defined as a machine that can far (...) surpass all the intellectual activities of any man however clever. Since the design of machines is one of these intellectual activities, an ultraintelligent machine could design even better machines; there would then unquestionably be an “intelligence explosion”, and the intelligence of man would be left far behind. Thus the first ultraintelligent machine is the last invention that man need ever make. The key idea is that a machine that is more intelligent than humans will be better than humans at designing machines. So it will be capable of designing a machine more intelligent than the most intelligent machine that humans can design. So if it is itself designed by humans, it will be capable of designing a machine more intelligent than itself. By similar reasoning, this next machine will also be capable of designing a machine more intelligent than itself. If every machine in turn does what it is capable of, we should expect a sequence of ever more intelligent machines. This intelligence explosion is sometimes combined with another idea, which we might call the “speed explosion”. The argument for a speed explosion starts from the familiar observation that computer processing speed doubles at regular intervals. Suppose that speed doubles every two years and will do so indefinitely. Now suppose that we have human-level artificial intelligence 1 designing new processors. Then faster processing will lead to faster designers and an ever-faster design cycle, leading to a limit point soon afterwards. The argument for a speed explosion was set out by the artificial intelligence researcher Ray Solomonoff in his 1985 article “The Time Scale of Artificial Intelligence”.1 Eliezer Yudkowsky gives a succinct version of the argument in his 1996 article “Staring at the Singularity”: “Computing speed doubles every two subjective years of work..

A number of philosophers endorse, without argument, the view that there’s something it’s like consciously to think that p, which is distinct from what it’s like consciously to think that q. This thesis, if true, would have important consequences for philosophy of mind and cognitive science. In this paper I offer an argument for it, and attempt to induce examples of it in the reader. The argument claims it would be impossible introspectively to distinguish conscious thoughts with respect to their (...) content if there weren’t something it’s like to think them.

According to the grounding theory of powers, fundamental physical properties should be thought of as qualities that ground dispositions. Although this view has recently been defended by many different philosophers, there is no consensus for how the view should be developed within a broader metaphysics of properties. Recently, Tugby has argued that the view should be developed in the context of a Platonic theory of properties, where properties are abstract universals. I will argue that the view should not be developed (...) within such a framework. Either the view should be developed with an ontology of Aristotelian properties, or it should be developed in a Nominalist framework that contains no properties at all. (shrink)

Conceptual engineering is the design, implementation, and evaluation of concepts. Conceptual engineering includes or should include de novo conceptual engineering (designing a new concept) as well as conceptual re-engineering (fixing an old concept). It should also include heteronymous (different-word) as well as homonymous (same-word) conceptual engineering. I discuss the importance and the difficulty of these sorts of conceptual engineering in philosophy and elsewhere.
