The larger part of Yearbook 6 of the Institute Vienna Circle constitutes the proceedings of a symposium on Alfred Tarski and his influence on and interchanges with the Vienna Circle, especially those on and with Rudolf Carnap and Kurt Gödel. It is the first time that this topic has been treated on such a scale and in such depth. Attention is mainly paid to the origins, development and subsequent role of Tarski's definition of truth. Some contributions are primarily historical, others (...) analyze logical aspects of the concept of truth. Contributors include Anita and Saul Feferman, Jan Wolenski, Jan Tarski and Hans Sluga. Several Polish logicians contributed: Gzegorczyk, Wójcicki, Murawski and Rojszczak. The volume presents entirely new biographical material on Tarski, both from his Polish period and on his influential career in the United States: at Harvard, in Princeton, at Hunter, and at the University of California at Berkeley. The high point of the analysis involves Tarski's influence on Carnap's evolution from a narrow syntactical view of language, to the ontologically more sophisticated but more controversial semantical view. Another highlight involves the interchange between Tarski and Gödel on the connection between truth and proof and on the nature of metalanguages. The concluding part of Yearbook 6 includes documentation, book reviews and a summary of current activities of the Institute Vienna Circle. Jan Tarski introduces letters written by his father to Gödel; Paolo Parrini reports on the Vienna Circle's influence in Italy; several reviews cover recent books on logical empiricism, on Gödel, on cosmology, on holistic approaches in Germany, and on Mauthner.

This is a “bottom-up” paper in the sense that it draws lessons in defining disciplinary categories under study from a series of empirical studies of interdisciplinarity. In particular, we are in the process of studying the interchange of research-based knowledge between Cognitive Science and Educational Research. This has posed a set of design decisions that we believe warrant consideration as others study cross-disciplinary research processes.

In the summer of 1957 at Cornell University the first of a cavalcade of large-scale meetings partially or completely devoted to logic took place--the five-week long Summer Institute for Symbolic Logic. That meeting turned out to be a watershed event in the development of logic: it was unique in bringing together for such an extended period researchers at every level in all parts of the subject, and the synergetic connections established there would thenceforth change the face of mathematical logic both (...) qualitatively and quantitatively. Prior to the Cornell meeting there had been nothing remotely like it for logicians. Previously, with the growing importance in the twentieth century of their subject both in mathematics and philosophy, it had been natural for many of the broadly representative meetings of mathematicians and of philosophers to include lectures by logicians or even have special sections devoted to logic. Only with the establishment of the Association for Symbolic Logic in 1936 did logicians begin to meet regularly by themselves, but until the 1950s these occasions were usually relatively short in duration, never more than a day or two. Alfred Tarski was one of the principal organizers of the Cornell institute and of some of the major meetings to follow on its heels. Before the outbreak of World War II, outside of Poland Tarski had primarily been involved in several Unity of Science Congresses, including the first, in Paris in 1935, and the fifth, at Harvard in September, 1939. (It was the latter which brought him to the United States and fortuitously left him stranded there following the Nazi invasion of Poland.) Much attention had been given to logic at these congresses and to Tarski’s own work, in particular, through the deep interest in it of Carnap, Quine and others. Following the end of the war, Tarski forged new alliances, especially in the United States logical and mathematical communities. To begin with, as part of the year-long celebration of the two-hundredth anniversary of the founding of Princeton University, a high-level conference on the Problems of Mathematics was held there in December 1946..

From the Federal Theater Projects of the Great Depression to the disruptive performances of the 1960s and 1970s, theater has played an important role in American radicalism. This special issue of_ _Theater_ reports on socially conscious, politically active theaters in the United States. Despite the evaporation of Cold War passions and the rise of conservatism in the 1980s and 1990s, such theater work remains a persistent and evolving presence on the political landscape. Since the first inauguration of George W. Bush, (...) new opportunities have arisen for political performance and for significant new challenges to these artists. T_heater and Social Change_ not only tracks the historical evolution of political theater but also explores the current state and future prospects of different modes, including agit-prop, demonstrations, solo performance, Augusto Boal’s Theater of the Oppressed, and community-based production. With such notable contributors as Anna Deavere Smith, Jonathan Kalb, Holly Hughes, and Tony Kushner, the issue offers a diverse assemblage of personal statements, conversations, photographs, interviews, and performance text. _Contributors include:_ Reverend Billy, Jan Cohen-Cruz, Arlene Goldbard, Sharon Green, Lani Guinier, Holly Hughes, Jonathan Kalb, Tony Kushner, Judith Malina, Robbie McCauley, John O'Neal, Claudia Orenstein, Bill Rauch, Julie Salverson, Anna Deavere Smith, Alisa Solomon, Roberta Uno.

Does the real world, defined as a world of objects that exist independent of human interests, concerns, and cognitive activities, really exist? Jan Westerhoff argues that we have good reason to believe it does not. His discussion considers four main facets of the idea of the real world, ranging from the existence of a separate external and internal world, to the existence of an ontological foundation that grounds the existence of all the entities in the world, and the existence of (...) an ultimately true theory that provides a final account of all there is. As Westerhoff discusses the reasons for rejecting the postulation of an external world behind our representations, he asserts that the internal world is not as epistemically transparent as is usually assumed, and that there are good reasons for adopting an anti-foundational account of ontological dependence. Drawing on conclusions from the ancient Indian philosophical system of Madhyamaka Buddhism, Westerhoff defends his stance in a purely Western philosophical framework, and affirms that ontology, and philosophy more generally, need not be conceived as providing an ultimately true theory of the world.

Jan Westerhoff unfolds the story of one of the richest episodes in the history of Indian thought, the development of Buddhist philosophy during the first millennium CE. He aims to offer the reader a systematic grasp of key Buddhist concepts such as non-self, suffering, reincarnation, karma, and nirvana.

This volume draws together important selections from the rich history of theories and debates about emotion. Utilizing sources from a variety of subject areas including philosophy, psychology, and biology, the editors provide an illuminating look at the "affective" side of psychology and philosophy from the perspective of the world's great thinkers. Part One features classic readings from Aristotle, Descartes, Spinoza, and Hume. Part Two, entitled "The Meeting of Philosophy and Psychology," samples the theories of thinkers such as Darwin, James, and (...) Freud. The third section presents some of the extensive work on emotion that has been done by European philosophers over the past century, and the final section comprises essays from modern British and American philosophers.

The aim of this book is a recovery of interest in the experience of meaning. Jan Zwicky defends the claim that we experience meaning in the apprehension of wholes and their internal structural relations, providing examples of such insight in mathematics and physics, literature, music, and Plato's ancient theory of forms. Taken together, these essays constitute a powerful indictment of the aggressive reductionism and the reliance on calculative modes of thought that dominate our present conception of understanding. The Experience of (...) Meaning proposes a more just epistemology, arguing for a new grammar of thought, a new way of understanding the relationship of human intelligence to the world. Engaging with philosophy, psychology, literature, fine arts, music, and environmental studies in a profound way, The Experience of Meaning will interest any reader who ponders the question of meaning and its relation to true human expression.

Nagarjuna's Vigrahavyavartani is one of the most important Madhyamaka Buddhist philosophical texts. Jan Westerhoff offers a new translation, reflecting the best current philological research and all available editions, and adds his own philosophical commentary on the text. His nuanced, philosophically sophisticated commentary explains Nagarjuna's arguments in a way that is both grounded in historical and textual scholarship and connected explicitly to contemporary philosophical concerns.

This is a collection of essays about logic and its applications to various philosophical problems. In general, it is argued that logic constitutes an important device of philosophical analysis. Concerning the nature of logic the author defends the thesis that first-order logic is the logic. Among the philosophical problems to which logic is applied in the essays are: truth, consistency, realism, foundations of semantics, psychologism, undetermination of theories by empirical data, modalities, value concepts, identity, vagueness, God's existence, transcendentals, legal reasoning, (...) category mistakes, bivalence, the cognitive relation, and meaningfulness.

This paper starts from a brief sketch of the ‘classical’ figure of critical educational theory or science (Kritische Erziehungswissenshaft). ‘Critical educational theory’ presents itself as the privileged guardian of the critical principle of education (Bildung) and its emancipatory promise. It involves the possibility of saying ‘I’ in order to speak and think in one's own name, to be critical, self-reflective and independent, to determine dependence from the present power relations and existing social order. Actual social and educational reality and relations (...) are approached as a limitation, threat, alienation, re/oppression or negation of ultimate human principles or potential. The task of critical educational theory becomes one of enabling an autonomous, critical, self-reflective life. While ‘critique’ and ‘autonomy’ have meanwhile become commonplace, and ‘critique’ and ‘autonomy’ are reclaimed and required from everybody, we should also consider the question of the relation between an institutional or ideological framework as that which claims to question this frame and to constitute its opposite. The trivialisation of critique is taken as occasion to recall Michel Foucault's analysis of power relations and especially his thesis according to which the ‘government of individualisation’ is the actual figure of power. Starting from the framework offered by Foucault, it can be made clear that the autonomous, critical, self-reflective life does not represent an ultimate principle but refers to a very specific form of subjectification operating as a transmission belt for power. The autonomous, critical, self-reflective person appears as an historical model of self-conduct whereby power operates precisely through the intensification of reflectiveness and critique rather than through their repression, alienation or negation. This brings us back then to the question of how to conceive of the task of a critical educational theory at a time in which critique, autonomy and self-determination have become an essential modus operandi of the existing order.

The article starts from the questions: what is it to be an inhabitant or citizen of a globalised world, and how are we to think of education in relation to such inhabitants? We examine more specifically the so–called ‘European area of higher education’ that is on the way to being established and that can be regarded as a concrete example of a process of globalisation. In the first part of the paper we try to show that the discursive horizon, and (...) the concrete techniques and strategies that accompany the establishment of this space of higher education, invite the inhabitants of that space to see themselves as entrepreneurial and autonomous entities. In the second part we show how this specific kind of subjectivation (this production of subjects), related as it is to this globalised space, involves what we call an immunisation that also affects our thinking and our ideas in and about education. To refer to this as a kind of immunisation implies that globalisation could in fact be considered a closing or enclosing rather than an opening up. We argue, therefore, that this immunisation needs to be refused in favour of the invention of other kinds of subjectivity, other ways of speaking and writing about the world and about education, such that we relate to ourselves in a different way.

I argue that Hannah Arendt's analysis of the development of modern society illuminates one aspect of prevailing educational discourse. We can understand the ‘learning society’ as both an effect and an instrument of the logic of ‘bare biological life’ or zoé that Arendt claims is the ultimate point of reference for modern society. In such a society we seem to live permanently under the threat of social exclusion, being permanently put in the position of learners or problem-solvers, without the right (...) of appeal. To imagine the possibility of such an appeal requires us to recover our sense of the experience of childhood. (shrink)

A proof of the (propositional) Craig interpolation theorem for cut-free sequent calculus yields that a sequent with a cut-free proof (or with a proof with cut-formulas of restricted form; in particular, with only analytic cuts) with k inferences has an interpolant whose circuit-size is at most k. We give a new proof of the interpolation theorem based on a communication complexity approach which allows a similar estimate for a larger class of proofs. We derive from it several corollaries: (1) Feasible (...) interpolation theorems for the following proof systems: (a) resolution (b) a subsystem of LK corresponding to the bounded arithmetic theory S 2 2 (α) (c) linear equational calculus (d) cutting planes. (2) New proofs of the exponential lower bounds (for new formulas) (a) for resolution ([15]) (b) for the cutting planes proof system with coefficients written in unary ([4]). (3) An alternative proof of the independence result of [43] concerning the provability of circuit-size lower bounds in the bounded arithmetic theory S 2 2 (α). In the other direction we show that a depth 2 subsystem of LK does not admit feasible monotone interpolation theorem (the so called Lyndon theorem), and that a feasible monotone interpolation theorem for the depth 1 subsystem of LK would yield new exponential lower bounds for resolution proofs of the weak pigeonhole principle.

This book is the first major account of political thought in twentieth-century Europe, both West and East, to appear since the end of the Cold War. Skillfully blending intellectual, political, and cultural history, Jan-Werner Müller elucidates the ideas that shaped the period of ideological extremes before 1945 and the liberalization of West European politics after the Second World War. He also offers vivid portraits of famous as well as unjustly forgotten political thinkers and the movements and institutions they inspired. Müller (...) pays particular attention to ideas advanced to justify fascism and how they relate to the special kind of liberal democracy that was created in postwar Western Europe. He also explains the impact of the 1960s and neoliberalism, ending with a critical assessment of today's self-consciously post-ideological age. (shrink)

Inspired by a mathematical ecology of thearre (M. Dinu) and the eco-grammar systems (E. Csuhaj-Varju et al.), this paper gives a brief analysis of simple cellular automata games in order to demonstrate their primary semiotic features. In particular, the behaviour of configurations in Conway's game of life is compared to several general features of Uexküll's concept of Umwelt. It is concluded that ecological processes have a fundamental semiotic dimension.

Following Foucault, ‘critique’ could be regarded as being the art not to be governed in this way or as a project of desubjectivation. In this paper it is shown how such a project could be described as an e‐ducative practice. It explores this idea through an example which Foucault himself gave of such a critical practice: the writing of ‘experience books’. Thus it appears that such an e‐ducative practice is a ‘dangerous’, public and uncomfortable practice that is not in need (...) of pastoral care but requires generosity, presence and attention. As such it demands a pedagogy of experience which is to be invented in order to ‘make’ oneself into a question, to transgress the limits of a governmental regime. (shrink)

A rigorous and wide-ranging discussion of the most ballyhooed emotion of all--and its surprising role in making us who we are. With Robert Solomon, Verna Gehring, and John Loughney.

We recall the notions of weak and strong Euler characteristics on a first order structure and make explicit the notion of a Grothendieck ring of a structure. We define partially ordered Euler characteristic and Grothendieck ring and give a characterization of structures that have non-trivial partially ordered Grothendieck ring. We give a generalization of counting functions to locally finite structures, and use the construction to show that the Grothendieck ring of the complex numbers contains as a subring the ring of (...) integer polynomials in continuum many variables. We prove the existence of a universal strong Euler characteristic on a structure. We investigate the dependence of the Grothendieck ring on the theory of the structure and give a few counter-examples. Finally, we relate some open problems and independence results in bounded arithmetic to properties of particular Grothendieck rings. (shrink)

Group judgements are often – implicitly or explicitly – influenced by their members’ individual expertise. However, given that expertise is seldom recognized fully and that some distortions may occur (bias, correlation, etc.), it is not clear that differential weighting is an epistemically advantageous strategy with respect to straight averaging. Our paper characterizes a wide set of conditions under which differential weighting outperforms straight averaging and embeds the results into the multidisciplinary group decision-making literature.

Jan G. Michel argues that we need a philosophy of scientific discovery. Before turning to the question of what such a philosophy might look like, he addresses two questions: Don’t we have a philosophy of scientific discovery yet? And do we need one at all? To answer the first question, he takes a closer look at history and finds that we have not had a systematic philosophy of scientific discovery worthy of the name for over 150 years. To answer the (...) second question, Michel puts forward three arguments that show the importance of a philosophy of scientific discovery. Briefly, he arrives at the following answers: No, we don’t yet have a philosophy of scientific discovery, and yes, we definitely need one. To remedy this shortcoming, Michel analyzes the concept of discovery, leading him to the insight that scientific discoveries have an underlying structure with certain structural features. Some of these features may be important but not indispensable to scientific discovery processes; these include eureka moments, serendipities, joint discoveries, special science funding, and others. In addition, Michel identifies three indispensable structural features which he examines in detail and which he places in a picture with a certain dynamics according to which the process of making scientific discoveries can be seen as a path, leading us from finding and acceptance to knowledge.

The Indian philosopher Acharya Nagarjuna was the founder of the Madhyamaka school of Mahayana Buddhism and arguably the most influential Buddhist thinker after Buddha himself. Indeed, in the Tibetan and East Asian traditions, Nagarjuna is often referred to as the 'second Buddha.' His primary contribution to Buddhist thought lies is in the further development of the concept of sunyata or 'emptiness.' For Nagarjuna, all phenomena are without any svabhaba, literally 'own-nature' or 'self-nature', and thus without any underlying essence. In this (...) book, Jan Westerhoff offers a systematic account of Nagarjuna's philosophical position. He reads Nagarjuna in his own philosophical context, but he does not hesitate to show that the issues of Indian and Tibetan Buddhist philosophy have at least family resemblances to issues in European philosophy.

The article investigates how two different conceptions of the edifying potential of education attempt to take into account the normative dimension of scientific knowledge. In the first conception it is the demand for truth that is edifying, whereas in the second concept it is a distinctively ethical demand. It is argued that the first concept in the end implies the subjection of education to the ‘brutality of facticity’, under which it risks losing its critical point. The second conception, drawing on (...) Levinas and Arendt, tries to safeguard this critical point. It conceives education as a process through which scientific knowledge is made subject to reflection, and is thus confronted with the ethical challenges and demands of society. (shrink)

The increasing emphasis on participation in education offers the starting point for this paper. Participation appears to be a strategic notion in a particular problematisation of education: this is installed through certain ways of speaking and writing (discourse) and through certain procedures, instruments and techniques that are proposed and developed in different places and spaces (technology). Participation is thereby claimed to empower individuals and to emancipate the child or the student from dominant regimes of power, including liberating them from oppressive (...) traditional educational practices. Foucault's concept of governmentality, which offers us a specific understanding of power, helps us to analyse the discourse and technology of participation in a different way: participation comes to be seen not as an increase in freedom and empowerment, but as an element in a particular mode of government or power. According to this analysis the plea for practices of participation appears as an interpellation or call, governing the way that people act and behave, and encouraging them to think of themselves in a very specific way. We characterise this in terms of immunisation. (shrink)

Tibetan Buddhist writings frequently state that many of the things we perceive in the world are in fact illusory, as illusory as echoes or mirages. In Twelve Examples of Illusion , Jan Westerhoff offers an engaging look at a dozen illusions--including magic tricks, dreams, rainbows, and reflections in a mirror--showing how these phenomena can give us insight into reality. For instance, he offers a fascinating discussion of optical illusions, such as the wheel of fire (the "wheel" seen when a torch (...) is swung rapidly in a circle), discussing Tibetan explanations of this phenomenon as well as the findings of modern psychology, and significantly clarifying the idea that most phenomena--from chairs to trees--are similar illusions. The book uses a variety of crystal-clear examples drawn from a wide variety of fields, including contemporary philosophy and cognitive science, as well as the history of science, optics, artificial intelligence, geometry, economics, and literary theory. Throughout, Westerhoff makes both Buddhist philosophical ideas and the latest theories of mind and brain come alive for the general reader. -/- "This delightful book offers a rich and satisfying philosophical feast to anyone interested in the phenomenon of illusion itself or in the Buddhist analysis of the human condition. Westerhoff draws together classical Buddhist scholarship, contemporary cognitive science and his own judicious philosophical reflection in a serious but refreshingly accessible engagement with the Buddhist tradition in the exploration of the role of illusion in our cognitive and emotional lives." Jay L. Garfield, author of Fundamental Wisdom of the Middle Way: Nagarjuna's Mulamadhyamakakarika -/- "Jan Westerhoff creatively juxtaposes an important Buddhist study of illusion with fascinating modern researches on illusory experiences, using the latter to illuminate the former. The result is a revealing account of the pervasiveness of illusion in our cognitive experience and the very structure of our cognitive apparatus.

Political theorists tend to dismiss the concept of constitutional patriotism for two main reasons. On the one hand, constitutional patriotism — understood as a post-national, universalist form of democratic political allegiance — is rejected on account of its abstract quality. On the otherhand, it is argued that constitutional patriotism, while apprearing universalist, is in fact particular through and through. According to this genealogical critique, it is held that constitutional patriotism might have been appropriate in the context when it originated — (...) namely West Germany, a half-nation with a deeply compromised sense of nationality on account of the Nazi past — but it is not universally applicable. This article reconstructs the origins of constitutional patriotism arguing that both the ‘protective’ and state-centred patriotism of Dolf Sternberger, and the ‘purifying’ patriotism of Jurgen Habermas — focused mainly on the public sphere — can indeed be understood as relying on ‘supplements of particularily’. However, there are also normative connections between universalist constitutional morality and militant democracy on the one hand, and universalist constitutionalist morality and an imperative to remember on the other. Thus, the genealogical critique by itself is insufficient to invalidate the idea of constitutional patriotism. (shrink)

This article discusses the question of poverty and wealth in light of several theses put forward by Larry Temkin. The claim that there is a sort of cosmic injustice involved when great disparities of ability or of wealth are found. He is concerned especially about disparities that are undeserved. It is agreed that this is unfortunate, but not agreed that they are unjust in a sense that supports the imposition of rectification on anyone else. Nor is poverty typically undeserved in (...) the only really relevant sense: the poor simply do not produce enough to earn them high incomes, and probably correct incomes they derive are indeed what such efforts are worth in the circumstances. That persons with very low incomes may merit our sympathy is accepted, but sympathy leads to charity, rather than to the involuntary exploitation of the better off. The essay concludes with further observations about the relevance of free markets, and points to the iniquities of the restrictions on commerce that are the most potent source of perpetuated poverty today.

Summary This article examines the complex nature of post-war Italian political thought, stressing the importance of Italy's unusual institutional and historical political arrangements, but also the vibrancy of its political ideologies in this period. In the past it has often been argued that the dysfunctional nature of post-war Italian democracy with its rapidly changing governments, and widespread corruption—which nonetheless coexisted with the one party, the Christian Democrats, being constantly in power—led to the atrophying of political theory in general, and political (...) ideologies in particular. But this picture is strongly disputed here—on the contrary it is argued that Christian Democratic, Left and liberal political ideologies were all complex and interesting. Thus if Christian democracy should ultimately be seen as an ‘ideology of transition’ which existed to help Catholicism adapt to the parameters of modern mass democracy, and which lacked a thinker of the calibre of Jacques Maritain, it nevertheless contained within it important debates on the role of the state, between such interesting thinkers as Giuseppe Dossetti and Alcide De Gasperi. And if anything, political thinking on the Left in the post-war period was even more complex, with visceral debates within the (large) Communist Party (PCI) over whether to work within the law—between such thinkers as Palmiro Togliatti and the Il Manifesto group. Equally on the more revolutionary Left, there were important debates about how quickly capitalism could be made to collapse through revolutionary action between thinkers such as Raniero Panzieri and his more radical disciples, Mario Tronti and Antonio Negri, while later, due to the general failure of these revolutionary efforts, post-modern thinkers such as Gianni Vattimo sought to abandon grand metaphysical narratives, whilst retaining a commitment to Left of centre political commitments. Finally, although not part of a widespread mass movement, the liberal thought of Norberto Bobbio was also highly interesting and sophisticated—borrowing from Hobbes and Kelsen, he sought to advocate a modest form of liberal democracy which allowed for civilised forms of conflict, and the protection of minorities, and which rejected the contention of Marxists that civil rights could not be distinguished from economic ones. Overall, if normative aspirations in post-war Italian politics were often frustrated in practice, this was certainly not due to any lack of theoretical vibrancy. (shrink)

Alkibiades, a central character in Plato's Symposium, claims that philosophy touches him to the quick. When Socrates speaks, he's often moved to tears and realizes he must change his life. In Alkibiades' Love, Jan Zwicky demonstrates that this image of philosophy is not anachronistic, but remains the living heart of the discipline. Philosophy can indeed matter to our lives, but for it to do so, we must reconceive the methods that, since the Enlightenment, have dominated its self-image in the West. (...) In these meticulously researched essays, Zwicky argues that analytic and poststructuralist philosophy are not simply fashions in academic discourse, but are manifestations of the technocracy which they sustain and promote. The alternative she develops, by showing it in action, is lyric philosophy - an integrated mode of understanding whose foundations lie in the way we comprehend music and metaphor. Written in lucid and powerful prose, Alkibiades' Love will interest a broad readership, from students of ancient Greek philosophy to ecologists seeking a coherent foundation for their work. Zwicky offers deep and original readings of Freud, Plato, and Simone Weil, and resuscitates Max Wertheimer's work, linking it to our comprehension of mathematics, metaphor, and ecological structures. Zwicky has been hailed as one of the most important and original thinkers of our time. Alkibiades' Love illuminates and extends her groundbreaking work while providing an accessible introduction for those coming to her thought for the first time. (shrink)

In this paper we present a dynamic assignment language which extends the dynamic predicate logic of Groenendijk and Stokhof [1991: 39–100] with assignment and with generalized quantifiers. The use of this dynamic assignment language for natural language analysis, along the lines of o.c. and [Barwise, 1987: 1–29], is demonstrated by examples. We show that our representation language permits us to treat a wide variety of donkey sentences: conditionals with a donkey pronoun in their consequent and quantified sentences with donkey pronouns (...) anywhere in the scope of the quantifier. It is also demonstrated that our account does not suffer from the so-called proportion problem.Discussions about the correctness or incorrectness of proposals for dynamic interpretation of language have been hampered in the past by the difficulty of seeing through the ramifications of the dynamic semantic clauses (phrased in terms of input-output behaviour) in non-trivial cases. To remedy this, we supplement the dynamic semantics of our representation language with an axiom system in the style of Hoare. While the representation languages of barwise and Groenendijk and Stokhof were not axiomatized, the rules we propose form a deduction system for the dynamic assignment language which is proved correct and complete with respect to the semantics.

We define a first-order extension LK(CP) of the cutting planes proof system CP as the first-order sequent calculus LK whose atomic formulas are CP-inequalities ∑ i a i · x i ≥ b (x i 's variables, a i 's and b constants). We prove an interpolation theorem for LK(CP) yielding as a corollary a conditional lower bound for LK(CP)-proofs. For a subsystem R(CP) of LK(CP), essentially resolution working with clauses formed by CP- inequalities, we prove a monotone interpolation theorem (...) obtaining thus an unconditional lower bound (depending on the maximum size of coefficients in proofs and on the maximum number of CP-inequalities in clauses). We also give an interpolation theorem for polynomial calculus working with sparse polynomials. The proof relies on a universal interpolation theorem for semantic derivations [16, Theorem 5.1]. LK(CP) can be viewed as a two-sorted first-order theory of Z considered itself as a discretely ordered Z-module. One sort of variables are module elements, another sort are scalars. The quantification is allowed only over the former sort. We shall give a construction of a theory LK(M) for any discretely ordered module M (e.g., LK(Z) extends LK(CP)). The interpolation theorem generalizes to these theories obtained from discretely ordered Z-modules. We shall also discuss a connection to quantifier elimination for such theories. We formulate a communication complexity problem whose (suitable) solution would allow to improve the monotone interpolation theorem and the lower bound for R(CP). (shrink)
