This article traces the development of possible worlds semantics through the work of: Wittgenstein, 1913-1921; Feys, 1924; McKinsey, 1945; Carnap, 1945-1947; McKinsey, Tarski and Jónsson, 1947-1952; von Wright, 1951; Becker, 1952; Prior, 1953-1954; Montague, 1955; Meredith and Prior, 1956; Geach, 1960; Smiley, 1955-1957; Kanger, 1957; Hintikka, 1957; Guillaume, 1958; Binkley, 1958; Bayart, 1958-1959; Drake, 1959-1961; Kripke, 1958-1965.

Contemporary hybrid logic is based on the idea of using formulas as terms, an idea invented and explored by Arthur Prior in the mid-1960s. But Prior’s own work on hybrid logic remains largely undiscussed. This is unfortunate, since hybridisation played a role that was both central to and problematic for his philosophical views on tense. In this paper I introduce hybrid logic from a contemporary perspective, and then examine the role it played in Prior’s work.

Arguably, the most promising and compelling route to demonstrating the significance of Hegel’s thought to contemporary philosophy has been the series of recent readings that construe Hegel as continuing and completing Kant’s Copernican turn. Paul Redding explicitly locates his interpretation within this program, seeing the hermeneutic dimension of Hegel’s thought as providing for the possibility of continuing the Kantian project. Kant’s Copernican turn can be loosely stated as the procedure of reflectively uncovering unexperienced conditions of experience that contribute to the (...) nature of experience in ways that require its further re-determination and re-description. What a hemeneutic take on this reflective procedure adds is that foremost among those conditions are contexts of intersubjective or dialogical relations—structures of recognition. While perhaps disappointing to anyone interested in the problem of textual interpretation, there is finally nothing more to Redding’s account of Hegel’s “hermeneutics” than the establishing of recognitive structures as forming the ultimate horizon of human experience. I take Redding’s relentless tracking of the problem of recognition to be one of his book’s virtues. (shrink)

There are various equivalent formulations of the Church-Turing thesis. A common one is that every effective computation can be carried out by a Turing machine. The Church-Turing thesis is often misunderstood, particularly in recent writing in the philosophy of mind.

This paper examines Hegel’s accounts of the nature of judgements and inferences in the ‘subjective logic’ of the Science of Logic, and does so in light of the history of the tradition of formal logic to his time. It is argued that, contrary to the attitude often displayed by interpreters of Hegel’s logic, it is important to understand the positive role played by formal logic, ‘logic commonly so called’, in Hegel’s own conception of logic. It is argued that Hegel’s own (...) scientific presentation [Darstellung] of logic relies on a dialectic working through the tradition of formal logic from Aristotle to Leibniz. The positions within the dialectic are most easily brought into focus in terms of the distinction between Aristotelian and Stoic logic, but they can also be seen as internal to Aristotelian logic. The logical tradition can be regarded as presenting a type of reductio ad absurdum, and a science of logic must examine what it was about Aristotle’s original project that brought it to this fate.

This paper examines Hegel’s claim that philosophy “has no other object than God‘ as a claim about the essentiality of the idea of God to philosophy. On this idealist interpretation, even atheistic philosophies would presuppose rationally evaluable ideas of God, despite denials of the existence of anything corresponding to those ideas. This interpretation is then applied to Hegel’s version of idealism in relation to those of two predecessors, Leibniz and Kant. Hegel criticizes the idea of the Christian God present within (...) his predecessors in terms of his own heterodox reading of the Trinity in order to resolve a paradox affecting them -- the “paradox of perspectivism‘.

This book defends a new interpretation of Hegel's theoretical philosophy, according to which Hegel's project in his central Science of Logic has a single organizing focus, provided by taking metaphysics as fundamental to philosophy, rather than any epistemological problem about knowledge or intentionality. Hegel pursues more specifically the metaphysics of reason, concerned with grounds, reasons, or conditions in terms of which things can be explained-and ultimately with the possibility of complete reasons. There is no threat to such metaphysics in epistemological (...) or skeptical worries. The real threat is Kant's Transcendental Dialectic case that metaphysics comes into conflict with itself. But Hegel, despite familiar worries, has a powerful case that Kant's own insights in the Dialectic can be turned to the purpose of constructive metaphysics. And we can understand in these terms the unified focus of the arguments at the conclusion of Hegel's Science of Logic. Hegel defends, first, his general claim that the reasons which explain things are always found in immanent concepts, universals or kinds. And he will argue from here to conclusions which are distinctive in being metaphysically ambitious yet surprisingly distant from any form of metaphysical foundationalism, whether scientistic, theological, or otherwise. Hegel's project, then, turns out neither Kantian nor Spinozist, but more distinctively his own. Finally, we can still learn a great deal from Hegel about ongoing philosophical debates concerning everything from metaphysics, to the philosophy of science, and all the way to the nature of philosophy itself.

The appearance of this translation is a major event in English-language Hegel studies, for it is more than simply a replacement for Wallace's translation cum paraphrase. Hegel's Prefaces to each of the three editions of the Enzyklopädie are translated for the first time into English. There is a very detailed Introduction translating Hegel's German, which serves not only as a guide to the translator's usage but also to Hegel's. Also included are a detailed bilingual annotated glossary, very extensive bibliographic and (...) interpretive notes to Hegel's text, an Index of References for works cited in the notes, a select Bibliography of recent works on Hegel's logic, and a detailed Index. The translation is guided by the principle that rendering Hegel’s logical thought clearly and consistently requires rendering his technical terms logically.... This ought immediately to become the standard translation of this important work. --Kenneth R. Westphal, in _Review of Metaphysics_. (shrink)

Part Two contains the text-in German and English-of the first two chapters of Hegel's Logic, which cover such categories as being, becoming, something, limit, ...

This 2007 book examines the possibilities for the rehabilitation of Hegelian thought within analytic philosophy. From its inception, the analytic tradition has in general accepted Bertrand Russell's hostile dismissal of the idealists, based on the claim that their metaphysical views were irretrievably corrupted by the faulty logic that informed them. These assumptions are challenged by the work of such analytic philosophers as John McDowell and Robert Brandom, who, while contributing to core areas of the analytic movement, nevertheless have found in (...) Hegel sophisticated ideas that are able to address problems which still haunt the analytic tradition after a hundred years. Paul Redding traces the consequences of the displacement of the logic presupposed by Kant and Hegel by modern post-Fregean logic, and examines the developments within twentieth-century analytic philosophy which have made possible an analytic re-engagement with a previously dismissed philosophical tradition.

'Modernity' has come to refer both to a contested historical category and to an even more contested philosophical and civilisational ideal. In this important collection of essays Robert Pippin takes issue with some prominent assessments of what is or is not philosophically at stake in the idea of a modern revolution in Western civilisation, and presents an alternative view. Professor Pippin disputes many traditional characterisations of the distinctiveness of modern philosophy. In their place he defends claims about agency, freedom, ethical (...) life and modernity itself, all of which are central to the German idealist philosophical tradition, and in particular, to the writings of Hegel. Having considered the Hegelian version of these issues the author explores other accounts as found in Habermas, Strauss, Blumenberg, Nietzsche, and Heidegger. (shrink)

Against the standard interpretation that Hegel's idealism, in particular speculative logic, should be understood as an extension of Kant's transcendental idealism, I argue that Hegel's Logic should be understood as a logic of actuality (Wirklichkeit). Rather than seeking to determine the necessary and merely formal conditions and categories for the knowledge of any possible object, speculative logic is the immanent and active process of determining the truth of actual objects and actuality itself. Through a discussion of the status of the (...) transition between the Phenomenology and the Logic, as well as a detailed reading of Hegel’s treatment of the modal categories in the Doctrine of Essence, I seek to show how speculative logic offers a way to think the unity of a thing and its conditions without reverting to pre-critical metaphysics. By breaking down the traditional distinctions between actuality, possibility, necessity, and contingency, as well as demonstrating the necessity of contingency in the activity of thinking, I suggest that Hegel provides us with the categories necessary for a new understanding of the relation between thought and reality beyond the Kantian frame.

Hegel makes claims about the relation of philosophy to religion that might raise concerns for those who want to locate his philosophy generally within the modern enlightenment tradition. For example, at the outset of his Lectures on Aesthetics he claims that philosophy “has no other object but God and so is essentially rational theology”.1 What might seem to placate worries here is that Hegel of course differentiates between the forms of religious and philosophical cognition in which such a content is (...) presented: while religion grasps this content in the form of imagistic or figurative representations [Vorstellungen], philosophy grasps it within conceptual thought, an attitude which might seem to align him with that found within the German enlightenment, for example, that found in Lessing and Kant. However, it seems undeniable that, in comparison to Kant, for example, Hegel employs forms of expression for the presentation of his own philosophical thought that are redolent with the type of imagistic and figurative locutions supposedly at home in religion. Moreover, the actual imagery employed seems to refer to the type of trinitarian version of Christianity that can seem antithetical to those forms of Christian thought that lent themselves to the sort of “demythologization” characteristic of the enlightenment attitude to religious doctrine. Such factors as these make it easy to portray Hegel’s philosophy as a type of irrationalist mysticism,2 or at least as a disguised theology with a content from revealed religion, and thus aligning him more to the spirit of the Counter-Enlightenment than the Enlightenment.
