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)

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)

A defining assumption in the debate on contextual influences on truth-conditional content is that such content is often incompletely determined by what is specified in linguistic form. The debate then turns on whether this is evidence for positing a more richly articulated logical form or else a pragmatic process of free enrichment that posits truly unarticulated constituents that are unspecified in linguistic form. Questioning this focus on semantics and pragmatics, this article focuses on the independent grammatical dimensions of the problem. (...) Against the background of a principled account of the different ways in which the lexicon and the grammar, respectively, determine aspects of propositional meaning, and an uncontentious notion of content, nothing turns out to be ‘missing’ in grammatical expressions in order for them to encode complete propositional thoughts. As this predicts, when putatively hidden constituents are made overt or are otherwise added, propositions result that are systematically different from the thoughts originally expressed. Context, while potentially affecting lexically specified aspects of meaning, never affects grammar-determined ones, suggesting a specific role for grammar in the normal cognitive mode. (shrink)

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.

This review summarizes recent experiments on neuronal mechanisms underlying goal-directed behaviour. We investigated two basic processes, the internally triggered initiation of movement and the processing of reward information. Single neurons in the striatum were activated a few seconds before self-initiated movements in the absence of external triggering stimuli. Similar activations were observed in the closely connected cortical supplementary motor area, suggesting that these activations might evolve through build up in fronto-basal ganglia loops. They may relate to intentional states directed at (...) movements and their outcomes. As a second result, neurons in the striatum were activated in relation to the expectation and detection of rewards. Since rewards constitute important goals of behaviour, these activitations might reflect the evaluation of outcome before the behavioural reaction is executed. Thus neurons in the basal ganglia are involved in individual components of goal-directed behaviour. (shrink)

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)

As world food and fuel prices threaten expanding urban populations, there is greater need for the urban poor to have access and claims over how and where food is produced and distributed. This is especially the case in marginalized urban settings where high proportions of the population are food insecure. The global movement for food sovereignty has been one attempt to reclaim rights and participation in the food system and challenge corporate food regimes. However, given its origins from the peasant (...) farmers' movement, La Via Campesina, food sovereignty is often considered a rural issue when increasingly its demands for fair food systems are urban in nature. Through interviews with scholars, urban food activists, non-governmental and grassroots organizations in Oakland and New Orleans in the United States of America, we examine the extent to which food sovereignty has become embedded as a concept, strategy and practice. We consider food sovereignty alongside other dominant US social movements such as food justice, and find that while many organizations do not use the language of food sovereignty explicitly, the motives behind urban food activism are similar across movements as local actors draw on elements of each in practice. Overall, however, because of the different histories, geographic contexts, and relations to state and capital, food justice and food sovereignty differ as strategies and approaches. We conclude that the US urban food sovereignty movement is limited by neoliberal structural contexts that dampen its approach and radical framework. Similarly, we see restrictions on urban food justice movements that are also operating within a broader framework of market neoliberalism. However, we find that food justice was reported as an approach more aligned with the socio-historical context in both cities, due to its origins in broader class and race struggles. (shrink)

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)

The possibility and extent of thought without language have been subject to much controversy. Insight from non- or minimally verbal humans can inform this debate empirically. Since most such individuals are on the autism spectrum, of which they make up a sizable 25–30%, an important connection between language and autism transpires. Here we propose a model which makes sense of this link and explains why the non-verbal human mind, as present evidence suggests, represents a fundamentally different cognitive phenotype. This model (...) views the relevant part of the autism spectrum as reflecting the breakdown of a cognitive phenotype of which language is an inherent element and which will manifest principled limitations in the latter's absence.

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.

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.

Houston Stewart Chamberlain, the „Evangelist of Racism“, had a major influence on German Emperor Wilhelm II, especially in forming his nationalistic and anti-Semitic views. The monarch and the author developed a mutual understanding and appreciation that lasted over 25 years. This article illuminates the circumstances of their initial acquaintance through the edition and analysis of two documents which were two hitherto unpublished documents: Chamberlain's diary for the dates 28.–31. 10. 1901 and a letter to his aunt Anne Guthrie of 11. (...) 11. 1901. Both documents are compared to other known reports of this meeting. Chamberlain accepted Wilhelm's invitation to Germany where they met in Liebenberg in 1901 in a circle of select members of the German aristocracy. Their first contact is reconstructed here showing the extent to which Wilhelm's thoughts coincided with those of Chamberlain. The author concludes that the meeting with Chamberlain in 1901 was most decisive in the development of Wilhelm's own thinking and had serious consequences for the later course of historical events. In addition, this first meeting is particularly interesting because of the participation of Adolf Harnack who was at that time very close to the Emperor and also corresponded with Chamberlain. The differences in character and views between Chamberlain, Wilhelm and Harnack also surfaced during this memorable meeting. (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)

To review a book that deals with 1000 years of Byzantine history is just as bold an undertaking as the writing of the book itself. Treadgold (henceforth T.) took this challenge on, and we should be grateful to him for doing so. The reviewer admits that he is not informed equally well over all periods of the history of the Byzantine empire – there is probably no-one on the planet who could with a clear conscience assert that they were. In (...) this respect the reviewer admires T. for his lack of reserve in expressing his views on problems and periods of Byzantine history with which he is clearly less familiar than with those of the eighth and ninth centuries.
