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)

Linguists have long sought to draw support from developmental disorders like Williams Syndrome (WS) and Specific Language Impairment (SLI) for linguistic theories and the modularity of language in particular. Linguistic diversity in the autism spectrum (ASD) has received comparatively little attention from linguists. Here I argue, against recent claims to the contrary, that language patterns in ASD do not support the modularity of language any more than WS or SLI are by now acknowledged to do. Rather, conceptualizing the linguistic diversity (...) in question requires integrated neurocognitive models in which language is an inherent aspect of human-specific forms of cognition, social interaction, and communication. ASD can be seen as providing us with important indications of how these are linked. (shrink)

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.

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)

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.

Theories of belief and meaning have long occupied philosophers. Typically, there is a correlation between the meaning of a sentence that is uttered and the content of the attitude that the speaker thereby conveys. This is also why a sentence can be used to specify content in an attribution of the attitude to the speaker. From the perspective of a theory of semantic content, there is a level of description where mental states and sentences can be said to share a (...) content or meaning. But there is a contrary view gaining currency, claiming that belief and meaning have to be kept apart conceptually, theoretically, and methodologically. Thus it could be that meaning is an internal or private notion that can be accounted for purely linguistically (or even non-intentionally altogether), while the same may not be true of belief. The volume brings together researchers from various areas in philosophy, psychology, and linguistics to address these questions. The tradition of logical positivism, sometimes thought of as having been a passing phase in twentieth-century philosophy, has as a matter of record remained a vibrant force. But it has shifted from broadside critiques of other systems of thought into a deeper study of how the structure of logic and language impact human behavior and psychological conditioning. Among the contributors to this international symposium are Michael Esfeld, Wolfram Hisses, Max Kolbel, Isaac Levi, Diego Marconi, James McGilvary, Olaf Muller, Paul Peitroski and Norbert Hornstein, Sebastian Rodl, and Alberto Voltolini.

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)

The question of 20th century philosophy was: how are we humans situated in our world? In forms of consciousness, as Husserl insistently analyzed, in language games, as Wittgenstein thought, or in a prior understanding of being, as Heidegger recommended? Wolfram Hogrebe summarizes these answers in what he calls scenic existence. This is grounded in certainties in which we experience ourselves sensitively 'tinted'. In this respect, forms of consciousness, language games and understanding of being are only built up from an (...) anonymous sonority. Wolfram Hogrebe has been following these circumstances for several years. In this new book, he delineates the project in historically informed, multi-faceted differentiations, terminating in a plea for a new enlightenment that may be understood as a program for our time.

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)

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)

Es gehort zu den Aufgaben unserer Gegenwart, das Format einer neuen Metaphysik zu entwickeln. In diesem Buch wird der Versuch unternommen, aus exemplarischen philosophischen Fragestellungen Klarungsstrategien zu entfalten, die allesamt anigmatische Grenzzonen erkunden, aus denen niemand herauszufinden vermag. Abwesenheiten in kreativen Prozessen, die Geburt der Intentionalitat, der switch vom ungeheuren Objekt zum ungeheuren Subjekt, die Entbindung von Kreativitat aus unscharfen semantischen Verhaltnissen, die Bedeutung von Bildung in Prozessen eines konzilianten Geltenlassens, Formen als Augen der Dinge und schliealich Kosmologie als Poetik: (...)

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

Much philosophical attention has been devoted to the truth predicates of natural language and their logic. However, lexical truth predicates are neither necessary nor sufficient for a truth-attribution to occur, which warrants closer attention to the grammar of truth attribution. A unified analysis of five constructions is offered here, in two of which the lexical truth predicate occurs (It's true that John left and That John left is true), while in the three remaining, it does not (John left; It seems (...) that John left; and It's that John left). This analysis is philosophically significant for four reasons. First, it explains why speakers of natural language find standard instances of Tarski-inspired equivalences (e.g. That John left is true iff John left) intuitively compelling. Second, it derives the widespread ‘deflationist’ intuition that truth has no substantive content. Third, insofar as the deflationist sees insights on truth as flowing from understanding our practice of truth attribution, it furthers the deflationist agenda through a new analysis of such attributions. Finally, it advances the philosophical project of the ‘naturalization’ of truth by reducing our understanding of truth to our competence in the grammar of truth, as an aspect of our biological endowment.

Internalism is an explanatory strategy that makes the internal structure and constitution of the organism a basis for the investigation of its external function and the ways in which it is embedded in an environment. It is opposed to an externalist explanatory strategy, which takes its departure from observations about external function and mind-environment interactions, and infers and rationalizes internal organismic structure from that. This paper addresses the origins of truth, a basic ingredient in the human conceptual scheme. I suggest (...) the necessity of pursuing an internalist line of explanation for it, as adopted in the biolinguistic program and generative grammar at large. According to this view, the concept of truth is a presupposition for the way language is used in relation to the world, rather than a function of that use or a consequence of language-world relations.

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)

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.

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)

In einer vereinzelten Anmerkung in den Bemerkungen über die Grundlagen der Mathematik scheint Wittgenstein die Existenz synthetischer Urteile a priori anzunehmen und damit ein entscheidendes Element der rationalistisch-transzendentalen Tradition. Ich argumentiere für eine Weise, in der sich diese Bemerkung in den größeren Zusammenhang von Wittgensteins Nachdenken über Mathematik einbettet, sowie für den kohärenten erkenntnistheoretischen Sinn, den sie unabhängig davon hat. Tatsächlich weist dieser weit über den Bereich bloß mathematischer Urteile hinaus. Beginnend mit einem empirisch-syntaktischen Begriff von Urteil, argumentiere ich, dass (...) die relevanten Urteile a priori darin sind, dass sich unsere Erfahrungen ihnen gegenüber verantworten und nicht umgekehrt die Urteile vor der Erfahrung. Sie sind gleichwohl synthetisch darin, dass sie nicht aus der Analyse von Begriffen allein entstehen und extern bedingt sind. Dass derlei Urteile in einem relevanten Sinne weder begründbar noch wahr-oder-falsch sind, scheint wie eine natürliche Konsequenz dessen, dass sie der inhärenten Struktur des menschlichen Geistes, und damit der menschlichen Natur, entspringen.

Über die Methoden der Lehre und die Lehrstätten der Philosophen der spätklassischen Zeit kursieren abenteuerliche Vorstellungen. Trotz einseitiger Quellenlage lassen sich die Wege von Sokrates in Athen, Platons Reisen nach Syrakus und Aristoteles Aufenthalte in Makedonien aber erstaunlich genau nachvollziehen. Philosophen nutzten für ihre Lehre bestimmte schattige Rundwege, um sich bei gleichmässiger Bewegung mit einem oder zwei Schülern auf einen dialogos zu konzentrieren. Schon für die Historiker der sp̈aten Antike wie Diogenes Laertius war dieses Verhalten zum Rätsel geworden. Das Phänomen (...) lässt sich dennoch erklären und sogar topographisch festlegen. Das Hauptaugenmerk gilt den Schulen der Philosophen. In vielen Fällen war damit der Peripatos gemeint, ein Bau-Typus, den Platon in der Akademie kreiert hatte. Wie er aussah, welche Räumlichkeiten vertreten waren und wie lange solche Lehrstätten Bestand hatten, ist Thema dieses Buches"--Publisher's website. (shrink)
