In the course of the debates on Priscian's notion of the perfect sentence, the philosopher Peter Abelard developed a theory that closely resembles modern accounts of propositional attitudes and that goes far beyond the established Aristotelian conceptions of the sentence. According to Abelard, the perfection of a sentence does not depend on the content that it expresses, but on the fact that the content is stated along with the propositional attitude towards the content. This paper tries to provide an (...) analysis and a consistent interpretation of Abelard's arguments within the framework of the mediaeval models of language and mind. (shrink)

This paper reconstructs a controversy between a pupil of Alberic of Paris and Peter Abelard which illustrates two competing ways of reconciling different ancient traditions. I shall argue that their accounts of the relation between sentences and thoughts are incompatible with one another, although they rely on the same set of sources. The key to understanding their different views on assertive and non-assertive sentences lies in their disparate views about the structure of thoughts: whereas Abelard takes thoughts to be (...) compositional, the opponent's arguments seem to rely on the premise that the mental states which correspond to sentences cannot be compositional in the way that Abelard suggested. Although, at a first glance, Abelard's position appears to be more coherent, it turns out that his opponent convincingly argues against weaknesses in Abelard's semantic theory by proposing a pragmatic approach.

If culture is defined as variation acquired and maintained by social learning, then culture is common in nature. However, cumulative cultural evolution resulting in behaviors that no individual could invent on their own is limited to humans, song birds, and perhaps chimpanzees. Circumstantial evidence suggests that cumulative cultural evolution requires the capacity for observational learning. Here, we analyze two models the evolution of psychological capacities that allow cumulative cultural evolution. Both models suggest that the conditions which allow the evolution of (...) such capacities when rare are much more stringent than the conditions which allow the maintenance of the capacities when common. This result follows from the fact that the assumed benefit of the capacities, cumulative cultural adaptation, cannot occur when the capacities are rare. These results suggest why such capacities may be rare in nature. (shrink)

Collective deliberation is fuelled by disagreements and its epistemic value depends, inter alia, on how the participants respond to each other in disagreements. I use this accountability thesis to argue that deliberation may be valued not just instrumentally but also for its procedural features. The instrumental epistemic value of deliberation depends on whether it leads to more or less accurate beliefs among the participants. The procedural epistemic value of deliberation hinges on the relationships of mutual accountability that characterize appropriately conducted (...) deliberation. I will argue that it only comes into view from the second-person standpoint. I shall explain what the second-person standpoint in the epistemic context entails and how it compares to Stephen Darwall’s interpretation of the second-person standpoint in ethics. (shrink)

Human social life is uniquely complex and diverse. Much of that complexity consists of culturally transmitted ideas and skills that underpin the operation of institutions that structure our social life. Considerable theoretical and empirical work has been devoted to the role of cultural evolutionary processes in the evolution of institutions. The most persistent controversy has been over the role of cultural group selection and gene-culture coevolution in early human populations the Pleistocene. We argue that cultural group selection and related cultural (...) evolutionary processes had an important role in shaping the innate components of our social psychology. By the Upper Paleolithic humans seem to have lived in societies structured by institutions, as do modern populations living in simple societies. The most ambitious attempts to test these ideas have been the use of experimental games in field settings to document human similarities and differences on theoretically interesting dimensions. These studies have documented a huge range of behavior cross-culturally, although no societies so far examined follow the expectations of selfish rationality. These data are at least consistent with operation of cultural group selection and gene-culture coevolution operating in the deep tribal past and with the contemporary importance of cultural evolution in the evolution of institutions and institutional diversity.

Für viele stellt das Instrumentalisierungsverbot, wonach man andere Menschen nie blo als Mittel behandeln darf, eine fundamentale moralische Wahrheit dar. Dieses Buch ist der Versuch, diese Ansicht näher zu fassen und zu begründen. Das Instrumentalisierungsverbot spielt nicht nur in unserer Alltagsmoral, sondern auch in moraltheoretischen Diskussionen eine wichtige Rolle. Verschiedenste Praktiken werden mit der Begründung als unzulässig kritisiert, dass mit ihnen Menschen instrumentalisiert würden. Doch was heit es, die anderen blo als Mittel zu behandeln? Es besteht, so wird in diesem (...) Buch argumentiert, ein Zusammenhang zwischen unzulässiger Instrumentalisierung und Verletzung der Würde von Personen. In der Explikation des Würdebegriffs wird dieser Zusammenhang entfaltet. Die unzulässige Instrumentalisierung von Personen verletzt in bestimmten Fällen deren Würde, in anderen Fällen Ansprüche, die in der Würde von Personen begründet sind. Die Würde von Personen wird dabei als Anspruch auf Selbstachtung gefasst. Selbstachtung wird nicht im Sinne der Selbstwertschätzung verstanden. Im Blick steht vielmehr ein normatives Verständnis von Selbstachtung, wonach Personen ein Leben in Selbstachtung führen, sofern ihr Selbstverfügungsrecht von anderen und ihnen selbst geachtet wird. Der Anspruch auf Selbstachtung wird als Anspruch darauf begriffen, über wesentliche Bereiche des eigenen Lebens verfügen zu können. Diese Überlegungen zu Würde und Selbstachtung werden moraltheoretisch eingeordnet und abschlieend auf paradigmatische Fälle der praktischen Ethik angewendet, bei denen es um die Instrumentalisierung von Menschen geht.

In his article In Between Us, Yoni van den Eede expands existing theories of mediation into the realm of the social and the political, focusing on the notions of opacity and transparency. His approach is rich and promising, but two pitfalls should be avoided. First, his concept of ‘in-between’ runs the risk to conceptualize mediation as a process ‘between’ pre-given entities. On the basis of current work in postphenomenology and actor-network theory, though, mediation should rather be seen as the origin (...) of entities, not as an intermediary between them. Second, Van den Eede’s separate discussion of transparency and opacity in ‘use’ and in ‘context’ runs the risk to make invisible the complementarity of the two dimensions. While transparency of use embodies an experiential form of the distinction between transparency and opacity, transparency of context embodies a more cognitive dimension of the distinction. Only by linking the two it becomes possible to take responsibility for the impact that technological mediations can have. Users and designers need a ‘double vision’ to simultaneously see the transparency of both use and context. (shrink)

Progress Unchained reinterprets the history of the idea of progress using parallels between evolutionary biology and changing views of human history. Early concepts of progress in both areas saw it as the ascent of a linear scale of development toward a final goal. The 'chain of being' defined a hierarchy of living things with humans at the head, while social thinkers interpreted history as a development toward a final paradise or utopia. Darwinism reconfigured biological progress as a 'tree of life' (...) with multiple lines of advance not necessarily leading to humans, each driven by the rare innovations that generate entirely new functions. Popular writers such as H. G. Wells used a similar model to depict human progress, with competing technological innovations producing ever-more rapid changes in society. Bowler shows that as the idea of progress has become open-ended and unpredictable, a variety of alternative futures have been imagined. (shrink)

Everyone allows that human and animal minds are distinctively (indeed, massively) different in their manifest effects. Humans have been able to colonize nearly every corner of the planet, from the artic, to deserts, to rainforests (and they did so in the absence of modern technological aids); they live together in large cooperative groups of unrelated individuals; they communicate with one another using the open-ended expressive resources of natural language; they are capable of cultural learning that accumulates over generations to result (...) in science, art, and agriculture; and they are remarkably thoughtful and inventive. There is much less agreement about how these manifest differences should be explained, however. (shrink)

Truthmaker theorists hold that propositions about higher-level entities (e.g. the proposition that there is a heap of sand) are often made true by lower-level entities (e.g. by facts about the configuration of fundamental particles). This generates a problem: what should we say about these higher-level entities? On the one hand, they must exist (since there are true propositions about them), on the other hand, it seems that they are completely superfluous and should be banished for reasons of ontological parsimony. Some (...) truthmaker theorists—most prominently David Armstrong—have tried to solve this puzzle by arguing that these entities are ‘an ontological free lunch’, i.e. real existents that are still ‘no addition of being’. This answer is prima facie attractive, but I argue in this paper that the standard approaches to truthmaking—modal theories and grounding theories—are unable to vindicate the doctrine of the ontological free lunch, and thus fail to solve the problem of higher-level entities. Fortunately, there is a non-standard account of truthmaking available, the reductive explanation account, which succeeds where the standard approaches fail. (shrink)

I reply to commentaries by Justin Bruner, Robert Sugden and Gerald Gaus. My response to Bruner focuses on conventions of bargaining problems and arguments for characterizing the just conventions of these problems as monotone path solutions. My response to Sugden focuses on how the laws of humanity present in Hume’s discussion of vulnerable individuals might be incorporated into my own proposed account of justice as mutual advantage. My response to Gaus focuses on whether or not my account of justice as (...) mutual advantage can incorporate deep differences in values across subgroups of a larger society. (shrink)

In this compelling and timely treatise, cultural theorist and educator Peter Trifonas puts forth the first book-length study of Jacques Derrida's 'educational texts:' that is, those writings most explicitly concerned with the ethics and politics of the historico-philosophical structures constituting the scene of teaching. The text examines how deconstruction allows us to re-think the socio-historical and ethico-philosophical aspects of pedagogical practices and policies, including pedagogical theories that have had direct bearing on the ethical and cultural ideals forming the reason (...) of Western educational systems and the exclusion of its 'Others.'.

I argue that common nouns should be analyzed as variables, rather than as predicates which take variables as arguments. This necessitates several unusual features to the analysis, such as allowing variables to be modally non-rigid, and assigning their values compositionally. However, treating common nouns as variables offers a variety of theoretical and empirical advantages over a more traditional analysis: It predicts the conservativity of nominal quantification, simplifies the analysis of articleless languages, derives the weak reading of sentences with donkey anaphora, (...) solves the proportion problem presented by quantifiers like ‘most’, improves the analysis of the temperature paradox, allows a more unified analysis of bare plurals, and regularizes the correspondence between syntactic categories and semantic types.

Al-Kindi was the first philosopher of the Islamic world. He lived in Iraq and studied in Baghdad, where he became attached to the caliphal court. In due course he would become an important figure at court: a tutor to the caliph's son, and a central figure in the translation movement of the ninth century, which rendered much of Greek philosophy, science, and medicine into Arabic. Al-Kindi's wide-ranging intellectual interests included not only philosophy but also music, astronomy, mathematics, and medicine. Through (...) deep engagement with Greek tradition al-Kindi developed original theories on key issues in the philosophy of religion, metaphysics, physical science, and ethics. He is especially known for his arguments against the world's eternity, and his innovative use of Greek ideas to explore the idea of God's unity and transcendence. Despite al-Kindi's historical and philosophical importance no book has presented a complete, in-depth look at his thought until now. In this accessible introduction to al-Kindi's works, Peter Adamson surveys what is known of his life and examines his method and his attitude towards the Greek tradition, as well as his subtle relationship with the Muslim intellectual culture of his day. Above all the book focuses on explaining and evaluating the ideas found in al-Kindi's wide-ranging philosophical corpus, including works devoted to science and mathematics. Throughout, Adamson writes in language that is both serious and engaging, academic and approachable. This book will be of interest to experts in the field, but it requires no knowledge of Greek or Arabic, and is also aimed at non-experts who are simply interested in one of the greatest of Islamic philosophers.

Among biological kinds, the most important are species. But species, however defined, have vague boundaries, both synchronically owing to hybridization and ongoing speciation, and diachronically owing to genetic drift and genealogical continuity despite speciation. It is argued that the solution to the problems of species and their vague boundaries is to adopt a thoroughgoing nominalism in regard to all biological taxa, from species to domains. The base entities are individual organisms: populations of these compose species and higher taxa. This accommodates (...) all the important biological facts while avoiding the legacy problems of pre-evolutionary typological taxonomy, which saw species and other taxa as prior to their members. Species are however not individuals: they are spatiotemporally bounded collections, which are plural particulars. (shrink)

An individual is agent-responsible for an outcome just in case it flows from her autonomous agency in the right kind of way. The topic of agent-responsibility is important because most people believe that agents should be held morally accountable (e.g., liable to punishment or having an obligation to compensate victims) for outcomes for which they are agent-responsible and because many other people (e.g., brute luck egalitarians) hold that agents should not be held accountable for outcomes for which they are not (...) responsible. In this paper, I examine how false beliefs affect agent-responsibility. Unlike most of the papers in this collection, my paper is on the notion of agent-responsibility that many believe is relevant to justice and morality generally. I do not here address the question of how, if at all, justice and morality are sensitive to agent-responsibility. (shrink)

The place of moral innocence in politics is the central theme of Peter Johnson's subtle and original book.

This paper provides a discussion of the role that emotions may play in the justification of punishment. On the expressivist account of punishment, punishment has the purpose of expressing appropriate emotional reactions to wrongdoing, such as indignation, resentment or guilt. I will argue that this expressivist approach fails as these emotions can be expressed other than through the infliction of punishment. Another argument for hard treatment put forward by expressivists states that punitive sanctions are necessary in order for the law (...) to be valid. But this justification of punishment, too, is unconvincing. There are no good reasons to assume that we have to resort to punitive measures in order to vindicate the law. I will then raise the more general worry whether there is any intelligible link at all between moral emotions such as indignation, resentment or guilt and retributive behaviour. I will finally conclude with some sceptical remarks on the moral worth of retribution. (shrink)

Virtue ethics is often proposed as a third way in health‐care ethics, that while consequentialism and deontology focus on action guidelines, virtue focuses on character; all three aim to help agents discern morally right action although virtue seems to have least to contribute to political issues, such as austerity. I claim: This is a bad way to characterize virtue ethics. The 20th century renaissance of virtue ethics was first proposed as a response to the difficulty of making sense of ‘moral (...) rightness’ outside a religious context. For Aristotle the right action is that which is practically best; that means best for the agent in order to live a flourishing life. There are no moral considerations besides this. Properly characterized, virtue ethics can contribute to discussion of austerity. A criticism of virtue ethics is that fixed characteristics seem a bad idea in ever‐changing environments; perhaps we should be generous in prosperity, selfish in austerity. Furthermore, empirical evidence suggests that people indeed do change with their environment. However, I argue that virtues concern fixed values not fixed behaviour; the values underlying virtue allow for different behaviour in different circumstances: in austerity, virtues still give the agent the best chance of flourishing. Two questions arise. In austere environments might not injustice help an individual flourish by, say, obtaining material goods? No, because unjust acts undermine the type of society the agent needs for flourishing. What good is virtue to those lacking the other means to flourish? The notion of degrees of flourishing shows that most people would benefit somewhat from virtue. However, in extreme circumstances virtue might harm rather than benefit the agent: such circumstances are to be avoided; virtue ethics thus has a political agenda to enable flourishing. This requires justice, a fortiori when in austerity. (shrink)

Peter Adamson offers an accessible, humorous tour through a period of eight hundred years when some of the most influential of all schools of thought were formed: from the third century BC to the sixth century AD. He introduces us to Cynics and Skeptics, Epicureans and Stoics, emperors and slaves, and traces the development of Christian and Jewish philosophy and of ancient science. Chapters are devoted to such major figures as Epicurus, Lucretius, Cicero, Seneca, Plotinus, and Augustine. But in (...) keeping with the motto of the series, the story is told 'without any gaps, ' providing an in-depth look at less familiar topics that remains suitable for the general reader. For instance, there are chapters on the fascinating but relatively obscure Cyrenaic philosophical school, on pagan philosophical figures like Porphyry and Iamblichus, and extensive coverage of the Greek and Latin Christian Fathers who are at best peripheral in most surveys of ancient philosophy. A major theme of the book is in fact the competition between pagan and Christian philosophy in this period, and the Jewish tradition also appears in the shape of Philo of Alexandria. Ancient science is also considered, with chapters on ancient medicine and the interaction between philosophy and astronomy. Considerable attention is paid also to the wider historical context, for instance by looking at the ascetic movement in Christianity and how it drew on ideas from Hellenic philosophy. From the counter-cultural witticisms of Diogenes the Cynic to the subtle skepticism of Sextus Empiricus, from the irreverent atheism of the Epicureans to the ambitious metaphysical speculation of Neoplatonism, from the ethical teachings of Marcus Aurelius to the political philosophy of Augustine, the book gathers together all aspects of later ancient thought in an accessible and entertaining way.

The paper discusses the question whether T-theories explain how it is possible to understand new sentences, or learn an infinite language, as Davidson claimed. I argue against some commentators that for explanatory power we need not require that T-theories are implicitly known or mirror cognitive structures. I note contra Davidson that the recursive nature of T-theories is not sufficient for explanatory power, since humans can work out only what is computationally tractable, and recursiveness by itself allows for intractable computational complexity. (...) I finally consider the complexity of T-theories, transformed into term rewriting systems, and find that the complexity of such systems is indeed tractable. Therefore Davidson's claim stands, even though a further condition had to be met. (shrink)
