Although Heidegger's relation to political philosophy is, at the very least, problematic, many figures who have contributed significantly to the field attended his courses in the 1920s (Hans-Georg Gadamer, Hannah Arendt, Hans Jonas, Joachim Ritter, Gunther Anders and others). Heidegger's work at that time was marked by an extensive engagement with Aristotle, and above all with Aristotle's practical philosophy. This article approaches the question of Heidegger as a political thinker by returning to his reading of Aristotle's practical philosophy in (...) order to clarify the structural features of his thinking that inspired so many of his students to develop a political philosophy clearly influenced by him. Heidegger reads the Nicomachean Ethics as an ontology of human existence, centred on an interpretation of human existence (Dasein) as práxis. This reading inspired a renaissance of practical philosophy in Germany and beyond. However, as Arendt has shown, Heidegger's ontologization closes práxis within a solipsistic horizon that deforms its political sense. It is this closure, which proves especially damaging when Heidegger begins to understand Dasein in relation to history and community, that many of his students have sought to reverse in their own work, thereby restoring a political dimension to a philosophy profoundly influenced by Heidegger.

According to the thesis of the extended mind (EM) , at least some token cognitive processes extend into the cognizing subject's environment in the sense that they are (partly) composed of manipulative, exploitative, and transformative operations performed by that subject on suitable environmental structures. EM has attracted four ostensibly distinct types of objection. This paper has two goals. First, it argues that these objections all reduce to one basic sort: all the objections can be resolved by the provision of an (...) adequate and properly motivated criterion—or mark—of the cognitive. Second, it provides such a criterion—one made up of four conditions that are sufficient for a process to count as cognitive. (shrink)

These essays On Hegel's political philosophy are taken from Ritter's influential Metaphysik and Politik. They discuss the importance of Hegel's evaluation of modernity by focusing upon his unique conceptions of property relations, morality, civil society, and the state.Ritter's work has played a seminal role in rekindling interest in Hegel's social and political philosophy. Ritter's clarity of expression makes Hegel's concepts accessible to a wide audience of philosophers, sociologists, political scientists, historians, and others concerned with the legitimacy of (...) modernity, the relation of society and the state, or in Hegel's relation to Marx and other later thinkers.Joachim Ritter was Professor of Philosophy at the University of Istanbul. This book is in the series Studies in Contemporary German Social Thought. (shrink)

Mark Balaguer’s project in this book is extremely ambitious; he sets out to defend both platonism and fictionalism about mathematical entities. Moreover, Balaguer argues that at the end of the day, platonism and fictionalism are on an equal footing. Not content to leave the matter there, however, he advances the anti-metaphysical conclusion that there is no fact of the matter about the existence of mathematical objects.1 Despite the ambitious nature of this project, for the most part Balaguer does not (...) shortchange the reader on rigor; all the main theses advanced are argued for at length and with remarkable clarity and cogency. There are, of course, gaps in the account but these should not be allowed to overshadow the sig-. (shrink)

For over twenty years, Mark McNulty has been documenting the Liverpool music scene, both in the city and as it has proliferated worldwide. Accompanied by over 100 photographs, Pop Cultured celebrates the city, its music, and its culture through the lens of this highly acclaimed and influential photographer. McNulty has covered a wide array of iconic British bands such as the Stone Roses, Happy Mondays, Echo and the Bunnymen, and the Arctic Monkeys, as well as visiting international acts like (...) the White Stripes. Witty, enthralling, and visually stunning, Pop Cultured combines McNulty’s images with his own laconic and humorous commentary and that of his iconic musical subjects, providing a rollercoaster account of the last twenty years of British culture.

Mark Jago presents an original philosophical account of meaningful thought: in particular, how it is meaningful to think about things that are impossible. We think about impossible things all the time. We can think about alchemists trying to turn base metal to gold, and about unfortunate mathematicians trying to square the circle. We may ponder whether God exists; and philosophers frequently debate whether properties, numbers, sets, moral and aesthetic qualities, and qualia exist. In many philosophical or mathematical debates, when (...) one side of the argument gets things wrong, it necessarily gets them wrong. As we consider both sides of one of these philosophical arguments, we will at some point think about something that’s impossible. Yet most philosophical accounts of meaning and content hold that we can’t meaningfully think or reason about the impossible. -/- In The Impossible, Jago argues that we often gain new information, new beliefs, and, sometimes, fresh knowledge through logic, mathematics, and philosophy. That is why logic, mathematics, and philosophy are useful. We therefore require accounts of knowledge and belief, of information and content, and of meaning which allow space for the impossible. Jago’s aim in this book is to provide such accounts. He gives a detailed analysis of the concept of hyperintensionality, whereby logically equivalent contents may be distinct, and develops a theory in terms of possible and impossible worlds. Along the way, he provides a theory of what those worlds are and how they feature in our analysis of normative epistemic concepts: knowledge, belief, information, and content. (shrink)

There is a new way of thinking about the mind that does not locate mental processes exclusively "in the head." Some think that this expanded conception of the mind will be the basis of a new science of the mind. In this book, leading philosopher Mark Rowlands investigates the conceptual foundations of this new science of the mind. The new way of thinking about the mind emphasizes the ways in which mental processes are embodied, embedded, enacted, and extended. The (...) new way of thinking about the mind, Rowlands writes, is actually an old way of thinking that has taken on new form. Rowlands describes a conception of mind that had its clearest expression in phenomenology -- in the work of Husserl, Heidegger, Sartre, and Merleau-Ponty. He builds on these views, clarifies and renders consistent the ideas of embodied, embedded, enacted, and extended mind, and develops a unified philosophical treatment of the novel conception of the mind that underlies the new science of the mind.

The Historical Dictionary of Philosophy, the _Historisches Wörterbuch der Philosophie,_ is distinguished by its particular presentation of philosophical terms, ideas and concepts. Rather than providing mere defintions or descriptive and analytical explanantions the _HWPh_ strictly applies the critical method of history of concepts developed by the eminent German scholar and philosopher Joachim Ritter. By means of precise and detailed references it documents the origin, first occurrence, the historical evolution and the changes of meaning of each concept, from Ancient Greek (...) to contemporary philosophy. For the reader this presentation is of unique value: it makes traceable the importance of terms and concepts at certain periods or for a particular philosopher, as well as its changes and development of meaning. Voulmes 1–12 of the _HWPh_ comprises more than 17.000 text columns on 3.670 philosophical terms. The dictionary does not include articles on persons. Volume 13 includes, besides of a comprehensive introductory essay, three different indexes: - the Subject Index classifies the articles by disciplinary and systematic categories - the Main Index includes all philosophical keywords with more than 30.000 references to their occurrences in other articles and contexts - the Author Index lists all authors and their contributions The included CD-ROM allows full text research of the _HWPh's_ entire content.

Kurz bevor Goethe in den Jahren 1808/9 die Wahlverwandtschaften schrieb, hatte sich sein ehemaliger naturwissenschaftlicher Kooperationspartner Johann Ritter in Untersuchungen zu Wünschelruten und Pendeln (1807/8) verloren, aus denen angeblich eine weitere tiefgreifende Analogie zwischen den Polaritäten in der Natur und denen beim Menschen hervorgehen sollte. Ritter arbeitete damals schon seit Jahren erfolgreich mit Goethes Polaritätsbegriff, und war dadurch sogar auf seinen größten Erfolg geleitet worden (die Entdeckung des UV-Lichts). So ist es nicht überraschend, dass sich Goethe für die (...) Pendelexperimente interessierte – und ihnen im Roman ein literarisches Denkmal setzte (während er sich wissenschaftlich dazu sicherheitshalber nicht äußerte). Die von beiden geteilte Polaritätsidee lief auf mehr hinaus als den vagen Gegensatz zwischen irgendwelchen antagonistischen Wirkfaktoren; vielmehr hatte sie handfeste strukturelle Implikationen im Sinne einer mathematischen Symmetrie: Bei Vertauschung der entgegengesetzten Pole in irgendeiner gegebenen Konfiguration kehren sich die ursprünglich beobachtbaren Wirkungen genau in ihr Gegenteil um. Diese Idee ist ein Kerngedanke der Farbenlehre (1810) und liegt z. B. Goethes Farbenkreis zugrunde; überraschenderweise lässt sie sich an einigen entscheidenden Wendepunkten der Wahlverwandtschaften präzise dingfest machen, und dadurch gewinnt ein beliebtes Spiel unter Goethelesern einen neuen Dreh: Die Farben des Farbenkreises haben eindeutig identifizierbare Gegenstücke im Personentableau des Romans.

In this book, Mark Rowlands challenges the Cartesian view of the mind as a self-contained monadic entity, and offers in its place a radical externalist or environmentalist model of cognitive processes. Cognition is not something done exclusively in the head, but fundamentally something done in the world. Drawing on both evolutionary theory and a detailed examination of the processes involved in perception, memory, thought and language use, Rowlands argues that cognition is, in part, a process whereby creatures manipulate and (...) exploit relevant objects in their environment. It is not simply an internal process of information processing; equally significantly, it is an external process of information processing. This innovative book provides a foundation for an unorthodox but increasingly popular view of the nature of cognition. (shrink)

J. L. Schellenberg has constructed major arguments for atheism based on divine hiddenness in two separate works. This paper reviews these arguments and highlights how they are grounded in reflections on perfect divine love. However, Schellenberg also defends what he calls the ‘subject mode’ of religious scepticism. I argue that if one accepts Schellenberg's scepticism, then the foundation of his divine-hiddenness arguments is undermined by calling into question some of his conclusions regarding perfect divine love. In other words, if his (...) scepticism is correct, then Schellenberg's case for atheism cannot stand. Finally, I demonstrate how my argument avoids the many defences that Schellenberg has employed thus far in defending these particular atheistic arguments. (shrink)

The recent philosophical literature on religious experience has mostly been concerned with experiences which are taken by the subject of the experience to be directly of God or some other supernatural entity, or to involve some suspension of the subject–object structure of conventional experience. In this paper I consider a further kind of experience, where the sense of God is mediated by way of an appreciation of the existential meanings which are presented by a material context. In this way the (...) paper aims to extend the standard philosophical concept of religious experience so as to take account of phenomenological treatments of sacred place, and to give more prominence to the materially mediated or sacramental character of much religious experience.

The central argument of this interesting paper is that Popper appears to be inconsistent: on the one hand, he preaches methodological monism-scientific method in the social sciences is identical to scientific method in the natural sciences-and on the other hand he advocates “situational analysis” as the unique method of the social sciences. Situational analysis is nothing but our old neoclassical friend, the rationality principle-individual maximizing behavior subject to constraints-and thus, Popper seems to be saying, neoclassical economics is the only valid (...) kind of social science.

What is the difference between right and wrong? This is no easy question to answer, yet we constantly try to make it so, frequently appealing to some hidden cache of cut-and-dried absolutes, whether drawn from God, universal reason, or societal authority. Combining cognitive science with a pragmatist philosophical framework in Morality for Humans: Ethical Understanding from the Perspective of Cognitive Science, Mark Johnson argues that appealing solely to absolute principles and values is not only scientifically unsound but even morally (...) suspect. He shows that the standards for the kinds of people we should be and how we should treat one another—which we often think of as universal—are in fact frequently subject to change. And we should be okay with that. Taking context into consideration, he offers a remarkably nuanced, naturalistic view of ethics that sees us creatively adapt our standards according to given needs, emerging problems, and social interactions. Ethical naturalism is not just a revamped form of relativism. Indeed, Johnson attempts to overcome the absolutist-versus-relativist impasse that has been one of the most intractable problems in the history of philosophy. He does so through a careful and inclusive look at the many ways we reason about right and wrong. Much of our moral thought, he shows, is automatic and intuitive, gut feelings that we follow up and attempt to justify with rational analysis and argument. However, good moral deliberation is not limited merely to intuitive judgments supported after the fact by reasoning. Johnson points out a crucial third element: we imagine how our decisions will play out, how we or the world would change with each action we might take. Plumbing this imaginative dimension of moral reasoning, he provides a psychologically sophisticated view of moral problem solving, one perfectly suited for the embodied, culturally embedded, and ever-developing human creatures that we are.

Mark Eli Kalderon presents an original study of perception, taking as its starting point a puzzle in Empedocles' theory of vision: if perception is a mode of material assimilation, how can we perceive colors at a distance? Kalderon argues that the theory of perception offered by Aristotle in answer to the puzzle is both attractive and defensible.

Thirteen seminal essays by Mark Richard develop a nuanced account of semantics and propositional attitudes. The collection addresses a range of topics in philosophical semantics and philosophy of mind, and is accompanied by a new Introduction which discusses attitudes realized by dispositions and other non-linguistic cognitive structures.

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)
