In any survey of recent developments in semantics, the game-theoretic approach to the semantics of both formal and of natural languages which has been developed by Jaakko Hintikka and his associates must loom large. It is indeed well known by this time that the semantics of the usual first-order logic can be spelled out in terms of games. What is not equally generally known is that this game-theoretical semantics can be augmented so as to apply also to natural languages and (...) not only to some of the artificial languages studied by logicians. The results already reached by Hintikka and his associates in this direction nevertheless show that many important phenomena of natural language can be handled in the game-theoretical framework. In this paper I shall first try to outline the basic ideas of the game-theoretical approach to semantics, then discuss briefly some problems which have so far been left untouched and thereby try to provide some new evidence for the naturalness and adequacy of a game-theoretical semantics.

In this collection of essays, some of the leading ecologists and philosophers discuss the foundations of ecology and evolutionary biology. While large scale philosophical convictions and attitudes often direct the theorist's line of concrete action in data collection and in theory information, the founda tional convictions typically remain tacit, and are seldom argued for. The present collection aims to remedy this situation. It brings together scholars representing different approaches in a joint effort to explicate and analyse some of the key (...) issues underlying ecological theorizing, be they conceptual, epistemological or ontological. The bulk of the present collection is reprinted from Synthese 43 (1980). William C. Wimsatt's paper 'Reductionistic Research Strategies and Their Biases in the Units of Selection Controversy' is in turn reprinted from T. Nickles (ed.) Scientific Discovery: Case Studies (D. Reidel, 1980). It appears here with the kind permission of Prof. Nickles. The publisher's consent for the reprints has been in each case automatic. The essays of Y rjo Haila and Olli Jarvinen, and of Leigh M. Van Valen appear here for the first time. In bringing the present collection together, as well as in editing the Synthese symposium on which it is based, I have greatly benefited from the suggestions of Professors Marjorie Grene, Olli J iirvinen and Daniel Simberloff. In addition to them, I wish to thank all the contributors for their interest in this project. (shrink)

_Imagologies: Media Philosophy_ is no ordinary book. Provocative, irritating and stimulating, this is a work to be engaged, questioned and pondered. As the web of telecommunications technology spreads across the globe, the site of economic development, social change, and political struggle shifts to the realm of media and communications. In this remarkable book, Mark Taylor and Esa Saarinen challenge readers to rethink politics, economics, education, religion, architecture, and even thinking itself. When the world is wired, nothing remains the same. To (...) explore the new electronic frontier with Taylor and Saarinen is to see the world anew. A revolutionary period needs a revolutionary book. Get a head start of the 21st Century: Read _Imagologies: Media Philosophy_. (shrink)

The aim of this article is to describe the significance and key challenges of philosophy for managers as perceived on the basis of a particular understanding of philosophy and my personal experience as a practitioner.The paper will be more visionary than argumentative. I recognise there are important alternative approaches but I will not engage in detailed analysis of them.2Drawing heavily on my own experience, the paper will present an outline and meta-philosophy of philosophical practices that have proven useful in actual (...) interface with practising managers.

In all semantical investigations the following two principles must be kept firmly in mind. First, never to confuse metaphysical with epistemological modalities and possibilities, second, to observe that it is the latter kind of modalities and possibilities that are relevant for semantics. In this paper I shall consider some celebrated cases of so-called direct reference (referential uses of definite descriptions, indexicals, demonstratives and proper names) and argue that the generally accepted views about these turn on not appreciating the two principles. (...) This renders them, I shall argue, semantically untenable. (shrink)

In this paper I discuss perception sentences of the following there syn- tactic types: John saw Mary John saw Mary run John saw that Mary run Our aim is to present an interpretation of Hintikka's logic of perception, extend it to case and dened the approach against the cirticism levelled against it by Jon Barwise.

SECTION I In 1972, Donald Davison and Gilbert Hannan wrote in the introduction to the volume Semantics of Natural Language: "The success of linguistics in treating natural languages as formal ~yntactic systems has aroused the interest of a number of linguists in a parallel or related development of semantics. For the most part quite independently, many philosophers and logicians have recently been applying formal semantic methods to structures increasingly like natural languages. While differences in training, method and vocabulary tend to (...) veil the fact, philosophers and linguists are converging, it seems, on a common set of interrelated problems. " Davidson and Harman called for an interdisciplinary dialogue of linguists, philosophers and logicians on the semantics of natural language, and during the last ten years such an enterprise has proved extremely fruitful. Thanks to the cooperative effort in these several fields, the last decade has brought about striking progress in our understanding of the semantics of natural language. This work on semantics has typically paid little attention to psychological aspects of meaning. Thus, psychologists or computer scientists working on artificial intelligence were not invited to join the forces in the influential introduction of Semantics of Natural Language. No doubt it was felt that while psychological aspects of language are important in their own right, they are not relevant to our immediate semantic concerns. In the last few years, several linguists and logicians have come to question the fundamental anti-psychological assumptions underlying their theorizing. (shrink)

In this paper I shall attempt to compare the dialogue approach originally advocated by Lorenz and Lorenzen and the game-theoretical approach of Hintikka with each other. I shall not try to present any survey of either one of the approaches and will assume that the reader is familiar with the basic ideas of these theories.The original works of Lorenzen and Lorenz have been reprinted in their while Stegmüller contains a survey (in English) of the basic ideas and results. Works in (...) this tradition which apply the approach to quantum logic include Denecke, Mittelstaedt Mittelstaedt and Stachow, Stachow. The reader will also find van Dunn, Krabbe, Lorenz and Stachow to be relevant.The literature on Hintikka’s game-theoretical semantics as applied both to different formal languages (including infinitary languages and intensional logic) and to natural language is rapidly growing. As for the latter, the reader is referred to papers by Hintikka, Carlson and myself reprinted in Saarinen, to Carlson and ter Meulen, and to Saarinen. (shrink)

This paper describes life-philosophical lecturing, as developed by the author, as a form of performing art and as a positive, oral and non-directive philosophical practice that revitalizes the Socratic ideal of philosophy. Life-philosophical lecturing is explicated as a systems-intelligent technology of the self.

I remember distinctly the moment I heard “All My Loving”, the first song by the Beatles I ever heard, in 1963 when I was 10 years of age. While puzzled by the unconventional long hair of the musicians of whom I had heard rumors, the music touched me. It felt right. I got a similar feeling when I started to read Carlin Romano’s hefty book in digital format one night in Athens whilst I was attending the World Congress of Philosophy. (...) I was impressed by its rakish humor, joyful style, its warm, friendly, inspired scholarship, and the author’s passion to uncover the relevance, grandeur and vitality of the philosophizing attitude as the author saw it. The book covered many thinkers far beyond my expertise and... (shrink)

The dialogical games introduced in Jaakko Hintikka, Information-Seeking Dialogues: A Model, (Erkenntnis, vol. 14, 1979) are studied here to answer the question as to what the natural logic or the logic of natural language is. In a natural language certain epistemic elements are not explicitly indicated, but they determine which inference rules are valid. By means of dialogical games, the question is answered: all classical first-order rules have to be modified in the same way in which some of them are (...) modified in the transition to intuitionistic logic. (Furthermore, in some cases quantificational rules have to be modified further.) The rules that are left unmodified by intuitionists are applicable only to the output of certain game rules, but not to others. In. this sense, neither classical nor yet intuitionistic logic is the logic of natural language. We need a new type of nonclassical logic, justified by our information-seeking dialogues. (shrink)
