This pioneering book lays new foundations for the study of reference and truth.

Life's Solution builds a persuasive case for the predictability of evolutionary outcomes. The case rests on a remarkable compilation of examples of convergent evolution, in which two or more lineages have independently evolved similar structures and functions. The examples range from the aerodynamics of hovering moths and hummingbirds to the use of silk by spiders and some insects to capture prey. Going against the grain of Darwinian orthodoxy, this book is a must read for anyone grappling with the meaning of (...) evolution and our place in the Universe. Simon Conway Morris is the Ad Hominen Professor in the Earth Science Department at the University of Cambridge and a Fellow of St. John's College and the Royal Society. His research focuses on the study of constraints on evolution, and the historical processes that lead to the emergence of complexity, especially with respect to the construction of the major animal body parts in the Cambrian explosion. Previous books include The Crucible of Creation (Getty Center for Education in the Arts, 1999) and co-author of Solnhofen (Cambridge, 1990). Hb ISBN (2003) 0-521-82704-3. (shrink)

Recent literature describing the process and pathways of the agrarian transition in Southeast Asia suggests that the rise of agricultural intensification and the growth of commodity markets will lead to the demise of swidden agriculture. This paper offers a longitudinal overview of the conditions that drive the agrarian transition amongst indigenous swidden cultivators and migrant paddy farmers in central Palawan Island, the Philippines. In line with regional agrarian change, we describe how a history of conservation policies has criminalized and pressured (...) swidden farmers to adopt more intensive “modern” agricultural practices. We examine how indigenous swidden cultivators adjust their practice in response to recent changes in policies, security of harvests, and socio-cultural values vis-à-vis intensification. Rather than suggest that this transition will lead to the demise of swidden, results reveal that farmers instead negotiate a shifting ground in which they lean on and value swidden as a means of negotiating agrarian change.

Apologies. The purpose of the following talk is to give an overview of the present state of aims, methods and results in Pure Proof Theory. Shortage of time forces me to concentrate on my very personal views. This entails that I will emphasize the work which I know best, i.e., work that has been done in the triangle Stanford, Munich and Münster. I am of course well aware that there are as important results coming from outside this triangle and I (...) apologize for not displaying these results as well.Moreover the audience should be aware that in some points I have to oversimplify matters. Those who complain about that are invited to consult the original papers.1.1. General. Proof theory startedwithHilbert's Programme which aimed at a finitistic consistency proof for mathematics.By Gödel's Theorems, however, we know that we can neither formalize all mathematics nor even prove the consistency of formalized fragments by finitistic means. Inspite of this fact I want to give some reasons why I consider proof theory in the style of Gentzen's work still as an important and exciting field of Mathematical Logic. I will not go into applications of Gentzen's cut-elimination technique to computer science problems—this may be considered as applied proof theory—but want to concentrate on metamathematical problems and results. In this sense I am talking about Pure Proof Theory.Mathematicians are interested in structures. There is only one way to find the theorems of a structure. Start with an axiom system for the structure and deduce the theorems logically. These axiom systems are the objects of proof-theoretical research. Studying axiom systems there is a series of more or less obvious questions. (shrink)

Philosophie ist wissentlicher Einhegungsversuch des Nichtwissens. Wo immer sie daher die Bedeutung und Wirksamkeit des Nichtwissens nicht präsent hält, verfehlt sie ihre Mitte. Das hat sich seit der Antike bis heute nicht geändert. Allerdings blieb es den Interessen der Zeiten und Denker vorbehalten, die Mischformen von Wissen und Nichtwissen in ihrer Eigenart mehr oder weniger eingehend zu analysieren. Selbst wenn die sokratische Formel vom Wissen des Nichtwissens durchgängig gerne zitiert wurde: Wie die Formen des Wissens in ihren schwachen, aber unentbehrlichen (...) Variationen näherhin zu charakterisieren sind, hat über die Zeiten die Philosophen eher selten interessiert. Aber diese schwachen Formen des Wissens wie Ahnung, Mutmaßung und das Gefühl als Grundlage von Situationseinschätzungen sind für unseren Alltag von erheblicher Bedeutung. Wolfram Hogrebe diskutiert in seinem Buch Formen des Wissens in ihrer szenischen Relevanz, ja das Szenische als Wissensform selbst. Ein von der Philosophie bislang völlig ignoriertes Thema. Aber die Philosophie kann gar nicht ignorieren, ohne dennoch auch in ihrem Absehen noch etwas Mitgesehenes hervortreten zu lassen. (shrink)

This chapter explores some fundamental consequences of the correspondence between physical process and computations. Most physical questions may be answerable only through irreducible amounts of computation. Those that concern idealized limits of infinite time, volume, or numerical precision can require arbitrarily long computations, and so be considered formally undecidable. The behavior of a physical system may always be calculated by simulating explicitly each step in its evolution. Much of theoretical physics has, however, been concerned with devising shorter methods of calculation (...) that reproduce the outcome without tracing each step. Computational irreducibility is common among the systems investigated in mathematics and computation theory, but it may well be the exception rather than the rule, since most physical questions may be answerable only through irreducible amounts of computation.

This book introduces generative grammar as an area of study and asks what it tells us about the human mind. Wolfram Hinzen lays the foundation for the unification of modern generative linguistics with the philosophies of mind and language. He introduces Chomsky's program of a 'minimalist' syntax as a novel explanatory vision of the human mind. He explains how the Minimalist Program originated in work in cognitive science, biology, linguistics, and philosophy, and examines its implications for work in these (...) fields. He considers the way the human mind is designed when seen as an arrangement of structural patterns in nature, and argues that its design is the product not so much of adaptive evolutionary history as of principles and processes that are ahistorical and internalist in character. Linguistic meaning, he suggests, arises in the mind as a consequence of structures emerging on formal rather than functional grounds. From this he substantiates an unexpected and deeply unfashionable notion of human nature. Clearly written in nontechnical language and assuming a limited knowledge of the fields it examines and links, Minimal Mind Design will appeal to a wide range of scholars in linguistics, philosophy, and cognitive science. It also provides an exceptionally clear insight into the nature and aims of Chomsky's Minimalist Program. (shrink)

In this, his latest book, Wolfram Hogrebe continues to unfold his project of an informal epistemology with an analysis of ties ("ligatures") to be found below the level of theoretically discussed norms, laws, and institutional regulations and nevertheless indispensable for a humane coexistence. Risks associated with such often hidden constellations of knowledge are also discussed. Master thinkers such as Schelling, Hegel, Heidegger, but also more marginal figures such as Felix Hausdorff alias Paul Mongré or artists such as Beuys are (...) discussed. In his inimitable style of concise yet succinct sketches, Hogrebe thus causes thinking to confront the often subtle nuances of being in a state of wonderment"--Publisher's website. (shrink)

We argue that the commonly accepted existence of grammatical concepts such as Person (in the grammatical sense) or Tense poses an unrecognized challenge to the idea that human thought is independent of language. The argument is that such concepts identify aspects of linguistic expressions that also systematically define the contents and identity of the thoughts expressed in language. Since grammatical concepts are not known to have non-grammatical analogues, the thoughts in question do not appear to be non-linguistic in nature. We (...) conclude that language is unlikely to be merely a medium in which independently constituted thoughts are expressed. (shrink)

The year is 1919. Walter Benjamin flees his overbearing father to scrape a living as a jobbing critic. Ludwig Wittgenstein signs away his inheritance to teach schoolchildren in a provincial Austrian village, seeking spiritual clarity. Martin Heidegger renounces his faith and align his fortunes with the phenomenological school of Edmund Husserl. Ernst Cassirer sketches a new schema of human culture at the back of a cramped Berlin tram. The stage is set for a great intellectual drama, which will unfold over (...) the next decade. The lives and thought of this quartet will converge and intertwine as each gains world historical significance, between them remaking philosophy. Time of the Magicians tells the story of this revolution in Western thought through the remarkable and turbulent lives of its four protagonists, showing philosophy not gifted from on high but worked out in the mess of everyday life, and illuminating with rare clarity their ideas.

I argue that the implementation of theDummettian program of an ``anti-realist'' semanticsrequires quite different conceptions of the technicalmeaning-theoretic terms used than those presupposed byDummett. Starting from obvious incoherences in anattempt to conceive truth conditions as assertibilityconditions, I argue that for anti-realist purposesnon-epistemic semantic notions are more usefully kept apart from epistemic ones rather than beingreduced to them. Embedding an anti-realist theory ofmeaning in Martin-Löf's Intuitionistic Type Theory(ITT) takes care, however, of many notorious problemsthat have arisen in trying to specify suitableintuitionistic (...) notions of semantic value,truth-conditions, and validity, taking into accountthe so-called ``defeasibility of evidence'' forassertions in empirical discourses.

Proposing a theory of the origins of human language ability and presenting an account of the early evolution of language, this text explains why humans are the only language-using animals and challenges the assumption that language is due to intelligence-- jacket cover.

This interdisciplinary book considers the relationship between language and thought from a philosophical perspective, drawing both on the philosophical study of language and the purely formal study of grammar, and arguing that the two should align. The claim is that grammar provides homo sapiens with the ability to think in certain grammatical ways and that this in turn explains the vast cognitive powers of human beings. Evidence is considered from biology, the evolution of language, language disorders, and linguistic phenomena.

The view that proper names are uniformly predicates has recently gained prominence. I review linguistic evidence against it. Overall, the linguistic evidence suggests that proper names function as predicates when they appear in a grammatically predicative position and as referential expressions when they are grammatically in a referential position. Conceptual grounds on which the predicativist view might nonetheless be upheld include ‘uniformity’, i.e., that a single semantic value be lexically specified for names in all of their occurrences irrespective of differences (...) in their grammar. However, ‘being a predicate’ or ‘being referential’ are not lexical properties of words but indications for how these grammatically function on an occasion of their use. Moreover, the intuitively referential and intuitively predicative uses of proper names precisely covary with grammatical differences. A proper name is therefore a predicate when it is predicatively used, not when its grammar and meaning are different. Given this grammar-meaning alignment there is no motivation to posit a novel ‘covert syntax’ for names in their referential uses, which breaks this alignment. Cross-linguistic evidence from languages such as Catalan, which features overt determiners in referential uses of proper names, moreover turns out to strongly support the view that the grammar of human language is systematically sensitive to differences in the referential and predicative uses of names.

Wolfram Hogrebe examines the anthropological relevance of logomantic [divinational] precursors of philosophy and poetry along with the idea of the implicit citizen and the nature of implicit musical structures.".

This essay focuses on the genetic text of Nietzsche’s unpublished poem An Hafis. Frage eines Wassertrinkers in order to establish the development of this poem from preliminary versions to an authoritative version. Through such a detailed philological analysis of the text in Nietzsche’s notebooks, it becomes increasingly clear that the final version of An Hafis constitutes an intertextual answer to Goethe’s West-östlicher Divan (1819/1827), which itself was inspired by the late-medieval Persian poet Hafez. Developing from different, and open-ended, semantic configurations (...) to a final version, Nietzsche’s An Hafis also allows us to reassess the editorial practices necessary to shed light on Nietzsche’s unpublished lyrical drafts.

Today’s globalization is merely a technical, in other words economic, military, information technology-based scientific embodiment of the unfathomable universality of human beings. The text therefore first sketches out a few profiles of philosophical universal proposals and a few ancient voices of the historians. Against this backdrop, the text explains an initial greater-space theory of Franz Rosenzweig and after this the diagnosis of the contemporary globalization process, which we owe to Joachim Ritter. Finally, the text presents a counter-concept of Carl Schmitt (...) that proceeded Ritter’s diagnosis by only a few years. (shrink)

Verkehrsmittel lassen sich als Medien betrachten, die auf die Wahrnehmung des Raums einwirken, aber auch als Milieus, die bestimmte Formen sozialer Interaktion erzeugen. Um beide Perspektiven aufeinander zu beziehen, umreißt der Beitrag eine Topologie der Fahrzeuge anhand von Stadttexten aus der französischen Literatur der Gegenwart. Aus deren eingehender Darstellung bestimmter Verkehrsmittel geht hervor, dass literarische Texte nicht allein fahrzeugspezifische Weisen der Raumerfahrung entziffern, sondern darüber hinaus auch in Auseinandersetzung mit einer überkommenen Transportkultur originelle Praktiken des Fahrzeuggebrauchs ersinnen. On the one (...) hand, means of transport can be considered as media which shape the perception of space; on the other, they can be considered as milieus which produce certain forms of social interaction. In order to relate both perspectives to each other, the present contribution outlines a topology of vehicles, drawing upon contemporary French literature set in cities. Their detailed representation of certain means of transport shows that literary texts not only decipher modes of spatial perception that are specific to certain vehicles, but also devise new ways of using vehicles through their involvement with an outdated culture of transport.

Wolfram Hogrebe beschäftigt sich in diesem Buch mit dem sogenannten Zwischenreich - einem alten philosophischen Gedanken, wonach das Philosophieren es mit einer Art von Zwischenraum zu tun hat, der die Ordnungen der Begriffe und der Vorstellungen in eine bemerkenswerte Schwebe bringt. Das Zwischen ist da gleichsam ein Medium, das die Gedanken und Sprachen trägt und so in zuweilen unbekannte Gebiete führt, in denen sich das Denken verändert. Hogrebe zeigt, wie sehr dieses Zwischen, das sich auch in Naturerfahrungen aufzuschliessen vermag, (...) Thema bei so unterschiedlichen Philosophen und Dichtern wie Gottfried Wilhelm Leibniz, Gotthold Ephraim Lessing, Martin Heidegger, Henry David Thoreau und Peter Handke ist. (shrink)

"What is mathematics?" is a question that has been debated since antiquity. This book presents a groundbreaking and surprising answer to the question-showing through the concept of the physicalization of metamathematics how both mathematics and physics as experienced by humans can be seen to emerge from the unique underlying computational structure of the recently formulated ruliad. Written with Stephen Wolfram's characteristic expositional flair and richly illustrated with remarkable algorithmic diagrams, the book takes the reader on a unprecedented intellectual journey (...) to the center of some of the deepest questions about mathematics and its nature-and points the way to a new understanding of the foundations and future of mathematics, taking a major step beyond ideas from Plato, Kant, Hilbert, Gödel and others.

A traditional view maintains that thought, while expressed in language, is non-linguistic in nature and occurs in non-linguistic beings as well. I assess this view against current theories of the evolutionary design of human grammar. I argue that even if some forms of human thought are shared with non-human animals, a residue remains that characterizes a unique way in which human thought is organized as a system. I explore the hypothesis that the cause of this difference is a grammatical way (...) of structuring semantic information, and I present evidence that the organization of grammar precisely reflects the organization of a specific mode of thought apparently distinctive of humans. Since there appears to be no known non-grammatical structuring principle for the relevant mode of thought, I suggest that grammar is that principle, with no independent ?Language of Thought? needed.

Mind–body dualism has rarely been an issue in the generative study of mind; Chomsky himself has long claimed it to be incoherent and unformulable. We first present and defend this negative argument but then suggest that the generative enterprise may license a rather novel and internalist view of the mind and its place in nature, different from all of, (i) the commonly assumed functionalist metaphysics of generative linguistics, (ii) physicalism, and (iii) Chomsky’s negative stance. Our argument departs from the empirical (...) observation that the linguistic mind gives rise to hierarchies of semantic complexity that we argue (only) follow from constraints of an essentially mathematical kind. We assume that the faculty of language tightly correlates with the mathematical capacity both formally and in evolution, the latter plausibly arising as an abstraction from the former, as a kind of specialized output. On this basis, and since the semantic hierarchies in question are mirrored in the syntactic complexity of the expression involved, we posit the existence of a higher-dimensional syntax structured on the model of the hierarchy of numbers, in order to explain the semantic facts in question. If so, syntax does not have a physicalist interpretation any more than the hierarchy of number-theoretic spaces does. (shrink)

Who thinks historically?A historian as such is like Melchizedek, fatherless and motherless, and without genealogy. When you ask him, “Where do you come from?” he must answer, “…I am a citizen of the world, and serve neither the Emperor, nor the King of France, but serve only the truth…”1But what is truth in historical thinking? What, or to be more precise, how, does it represent? How does it establish a certain relationship between its objective correlates, “[f]or falsity and truth have (...) to do with combination and separation”?2In our language the term History [Geschichte] unites….
