Jaakko Hintikka – författare

Most current work in epistemology deals with the evaluation and justification of information already acquired. In this book, Jaakko Hintikka instead discusses the more important problem of how knowledge is acquired in the first place. His model of information-seeking is the old Socratic method of questioning, which has been generalized and brought up-to-date through the logical theory of questions and answers that he has developed. Hintikka also argues that philosophers' quest for a definition of knowledge is ill-conceived and that the entire notion of knowledge should be replaced by the concept of information. He offers an analysis of the different meanings of the concept of information and of their interrelations. The result is a new and illuminating approach to the field of epistemology.

This book, written by one of philosophy's pre-eminent logicians, argues that many of the basic assumptions common to logic, philosophy of mathematics and metaphysics are in need of change. It is therefore a book of critical importance to logical theory. Jaakko Hintikka proposes a new basic first-order logic and uses it to explore the foundations of mathematics. This new logic enables logicians to express on the first-order level such concepts as equicardinality, infinity, and truth in the same language. The famous impossibility results by Gödel and Tarski that have dominated the field for the last sixty years turn out to be much less significant than has been thought. All of ordinary mathematics can in principle be done on this first-order level, thus dispensing with the existence of sets and other higher-order entities.

Quine's advice to give up logi- cal modalities as being beyond repair.

Most of the papers appearing in volume 87 numbers, 1-2 are based on papers presented at the Colloquium on the Philosophy of Ludwig Wittgenstein held at the Department of Philosophy at Florida State University on 7-8 April 1989. We owe warm thanks to Florida State University for generously supporting this colloquium. The English translation of the chapter entitled 'Philosophie', from Wittgenstein's typescript number 213 (von Wright), appears here with permission of Wittgenstein's literary heirs, without affecting existing copyrights. The original German version of this chapter was edited by Heikki Nyman and appeared in Revue Internationale de Philosophie 43 (1989), pp. 175-203. Jaakko Hintikka's article (87, No.2) first appeared in a shorter form in The Times Literary Supplement No. 4565 (28 September to 4 October 1990, p. 1030). The present version appears with the permis­ sion of The Times Literary Supplement, which is gratefully acknowl­ edged.

Metaphor is one of the most frequently evoked but at the same time most poorly understood concepts in philosophy and literary theory. In recent years, several interesting approaches to metaphor have been presented or outlined. In this volume, authors of some of the most important new approaches re-present their views or illustrate them by means of applications, thus allowing the reader to survey some of the prominent ongoing developments in this field. These authors include Robert Fogelin, Susan Haack, Jaakko Hintikka (with Gabriel Sandu), Bipin Indurkhya and Eva Kittay (with Eric Steinhart). Their stance is in the main constructive rather than critical; but frequent comparisons of different views further facilitate the reader's overview. In the other contributions, metaphor is related to the problems of visual representation (Noel Carroll), to the open class test (Avishai Margalit and Naomi Goldblum) as well as to Wittgenstein's idea of 'a way of life' (E.M. Zemach).

Discussions of the foundations of mathematics and their history are frequently restricted to logical issues in a narrow sense, or else to traditional problems of analytic philosophy. This work illustrates the much greater variety of the actual developments in the foundations during the period covered. The viewpoints that serve this purpose included the foundational ideas of working mathematicians, such as Kronecker, Dedekind, Borel and the early Hilbert, and the development of notions like model and modelling, arbitrary function, completeness, and non-Archimedean structures. The philosophers discussed include not only the household names in logic, but also Husserl, Wittgenstein and Ramsey. Needless to say, such logically-oriented thinkers as Frege, Russell and Godel are not entirely neglected, either. Anyone interested in the philosophy and/or history of mathematics should find this book of interest.

Frequently, a genuine understanding of a thinker's ideas is possible only by following them further than he did himself. Wittgenstein's Viennese contemporary Karl Kraus spoke in a similar context of one-and-a-half truths in contradistinction to half-truths. In this volume of essays, Jaakko Hintikka examines the two grand visions concerning the interrelations of language, self and the world that guided Wittgenstein's thought at the different stages of his philosophical development. He seeks to show how one of them, the so-called picture theory of language, was in reality a combination of several independent assumptions, while the other, the idea of language-games as the vehicles of meaning, was the end product of an intriguing development. Hintikka asserts that many of Wittgenstein's best-known ideas can, and must, be understood as defences or rationalizations of his overall visions. In several essays, Wittgenstein's ideas are illuminated through comparisons with other philosophers, including Russell, Husserl and Carnap.

The essays collected here explore a fundamental contrast between two overall visions of language and its availability to self-examination. They can be characterized as "language as the universal medium" and "language as calculus" (or the model-theoretical view). The former normally includes the ineffability of semantics and a one-world ontology. This contrast has dominated twentieth-century philosophy but has scarcely been acknowledged before. Philosophers examined here from the vantage point of the contrast include Peirce, Frege, Wittgenstein, Carnap, Quine, Husserl and Heidegger. Tarski's famous result concerning the indefinability of truth seems to decide the issue in favor of the universalists. Hintikka nevertheless shows that Tarski's result is inconclusive and that truth can in fact be defined in languages which are in certain respects comparable to ordinary language. This unique volume is a must for every contemporary philosopher and for everyone interested in the semantics of our language.

IF WITI'GENSTEIN COULD TALK, COULD WE UNDERSTAND HIM? Perusing the secondary literature on Wittgenstein, I have frequently experienced a perfect Brechtean Entfremdungseffekt. This is interesting, I have felt like saying when reading books and papers on Wittgenstein, but who is the writer talking about? Certainly not Ludwig Wittgenstein the actual person who wrote his books and notebooks and whom I happened to meet. Why is there this strange gap between the ideas of the actual philosopher and the musings of his interpreters? Wittgenstein is talking to us through the posthumous publication of his writings. Why don't philosophers understand what he is saying? A partial reason is outlined in the first essay of this volume. Wittgenstein was far too impatient to explain in his books and book drafts what his problems were, what it was that he was trying to get clear about. He was even too impatient to explain in full his earlier solutions, often merely referring to them casually as it were ina shorthand notation. For one important instance, in The Brown Book, Wittgenstein had explained in some detail what name-object relationships amount to in his view. There he offers both an explanation of what his problem is and an account of his own view illustrated by means of specific examples of language-games. But when he raises the same question again in Philosophical Investigations I, sec.

One can distinguish, roughly speaking, two different approaches to the philosophy of mathematics. On the one hand, some philosophers (and some mathematicians) take the nature and the results of mathematicians' activities as given, and go on to ask what philosophical morals one might perhaps find in their story. On the other hand, some philosophers, logicians and mathematicians have tried or are trying to subject the very concepts which mathematicians are using in their work to critical scrutiny. In practice this usually means scrutinizing the logical and linguistic tools mathematicians wield. Such scrutiny can scarcely help relying on philosophical ideas and principles. In other words it can scarcely help being literally a study of language, truth and logic in mathematics, albeit not necessarily in the spirit of AJ. Ayer. As its title indicates, the essays included in the present volume represent the latter approach. In most of them one of the fundamental concepts in the foundations of mathematics and logic is subjected to a scrutiny from a largely novel point of view. Typically, it turns out that the concept in question is in need of a revision or reconsideration or at least can be given a new twist. The results of such a re-examination are not primarily critical, however, but typically open up new constructive possibilities. The consequences of such deconstructions and reconstructions are often quite sweeping, and are explored in the same paper or in others.

Several central concepts and ideas of language theory are analyzed, criticized and developed in the essays contained in this volume. They include the concept of quantifier and in particular a liberalization of the rules governing the interaction of quantifiers, the ambiguities of the concept of scope, the alleged Frege-Russell ambiguity of words for being, the notion of reference which turns out to be misunderstood by the so-called "new theorists of reference", different modes of identification, the hegemony of generative syntax, recent theories of demonstratives, the relation of verificationist and truth-conditional meaning theories, the notion of metaphor, and differences between alethic and epistemic language-games. A bird's-eye view of current language theory is provided by an examination of the differences between rule-oriented paradigms.

Inquiry in the sense of knowledge-seeking becomes inquiry in the sense of interrogation. Using this new logic, Hintikka establishes a result that will be considered among the fundamental theorems of all epistemology, of the virtual identity of optimal strategies of pure discovery with optimal deductive strategies. Hintikka shows, in fact, how the logic of experimental inquiry can be understood from the interrogative vantage point. Other topics examined include induction (in a forgotten sense that has nevertheless played a role in science), explanation, the incommensurability of theories, theory-ladenness of observations, and identifiability.

On the occasion of bis sixtieth birthday, we dedicate this volume to Jan Wo­ leriski-s-our teacher, our colleague, our friend. Both of us are particularly indebted to Jan not only with regards to profes­ sional matters, but some private ones as well. Hence, we hope that he forgives us an occasional lapse into fondness and affection. That said, may the list of bis personalmerits remain shrouded in mystery; rather than unveil them, we open here by appraising Jan's presence from a broader perspective. Tonote that Jan was not always a part of our lives would not evoke surprise. However, to imagine the Institute of Pbilosophy on Grodzka Street or Krakow pbilosophy without him in it would be a harder task-at least for us, Nonethe­ less, we do remember the days when he was commuting to Krakow as a guest lecturer. Is there anything about those days which particularly comes to mind? To shed light on the story which follows, one must begin by stating that the early 1980s when we were studying philosophy was not a bright period. The great masters of Krakow philosophy-Ingarden, Mehlberg, Zawirski, or Dambska-> were either dead or, for political reasons, kept silent. The years following Martial Law (1981-1983) were intellectually very blighted and barren. In the midst of all this we were attending Jan's course on general methodology.

Aristotle thought of his logic and methodology as applications of the Socratic questioning method. In particular, logic was originally a study of answers necessitated by earlier answers. For Aristotle, thought-experiments were real experiments in the sense that by realizing forms in one's mind, one can read off their properties and interrelations. Treating forms as independent entities, knowable one by one, committed Aristotle to his mode of syllogistic explanation. He did not think of existence, predication and identity as separate senses of estin. Aristotle thus serves as an example of a thinker who did not rely on the distinction between the allegedly different Fregean senses, thereby shedding new light on our own conceptual presuppositions. This collection comprises several striking interpretations that Jaakko Hintikka has put forward over the years, constituting a challenge not only to Aristotelian scholars and historians of ideas, but to everyone interested in logic, epistemology or metaphysics and in their history.

Vol. 1: Ludwig Wittgenstein: Half-Truths and One-and-a-Half-TruthsBecause of his legendary impatience, Wittgenstein's published books are focused on his solutions to his latest problems and consequently often fail to explain not only his earlier solutions but also his problem situation. In the essays collected in this volume, Jaakko Hintikka counteracts the difficulty which this peculiarity of Wittgenstein's poses to his readers by analysing in depth the crucial stages of Wittgenstein's philosophical career and the relation of his ideas to those of other philosophers, especially Russell, Carnap and Husserl, with sometimes surprising results. Vol. 2: Lingua Universalis vs. Calculus RatiocinatorTwentieth-century philosophy has tacitly been dominated by a deep contrast between universalist and model-theoretical visions of language. The role of this contrast is studied here in Peirce, Frege, Wittgenstein, Carnap, Quine, Husserl, Heidegger and in the development of logical theory. Hintikka also develops a new approach to truth-definitions which strongly supports the model-theoretical view.Vol. 3: Language, Truth and Logic in MathematicsThe foundations of mathematics are examined by reference to such crucial concepts as the informational independence of quantifiers, the standard-nonstandard distinction, completeness, computability, parallel processing and the extremality of models.Vol. 4: Paradigms for Language Theory and Other EssaysSeveral of the basic ideas of current language theory are subjected to critical scrutiny and found wanting, including the concept of scope, the hegemony of generative syntax, the Frege-Russell claim that verbs like `is' are ambiguous, and the assumptions underlying the so-called New Theory of Reference. In their stead, new constructive ideas are proposed.Vol. 5: Inquiry as Inquiry: A Logic of Scientific DiscoveryIn the essays collected here, Hintikka both defends and outlines a genuine logic of scientific discovery, the logic of questions and answers. Thus inquiry in the sense of knowledge-seeking becomes inquiry in the sense of interrogation. Using this new logic, Hintikka establishes a result that will undoubtedly be considered the fundamental theorem of all epistemology, viz., the virtual identity of optimal strategies of pure discovery with optimal deductive strategies.Vol. 6: Analyses of AristotleThis collection comprises several striking interpretations of Aristotle's logic and methodology that Jaakko Hintikka has put forward over the years, constituting a challenge not only to Aristotelian scholars and historians of ideas, but to everyone interested in logic, epistemology or metaphysics and in their history.

It is gratifying to see that philosophers' continued interest in Words and Objections has been so strong as to motivate a paperback edition. This is gratifying because it vindicates the editors' belief in the permanent im­ portance of Quine's philosophy and in the value of the papers com­ menting on it which were collected in our volume. Apart from a couple of small corrections, only one change has been made. The list of Professor Quine's writings has been brought up to date. The editors cannot claim any credit for this improvement, however. We have not tried to imitate the Library of Living Philosophers volumes and to include Professor Quine's autobiography in this volume, but we are fortunate to publish here his brand-new auto bibliography. 1975 THE EDITORS TABLE OF CONTENTS V PREFACE 1 EDITORIAL INTRODUCTION 1. 1.

The papers collected in this volume were written over a period of some eight or nine years, with some still earlier material incorporated in one of them. Publishing them under the same cover does not make a con­ tinuous book of them. The papers are thematically connected with each other, however, in a way which has led me to think that they can naturally be grouped together. In any list of philosophically important concepts, those falling within the range of application of modal logic will rank high in interest. They include necessity, possibility, obligation, permission, knowledge, belief, perception, memory, hoping, and striving, to mention just a few of the more obvious ones. When a satisfactory semantics (in the sense of Tarski and Carnap) was first developed for modal logic, a fascinating new set of methods and ideas was thus made available for philosophical studies. The pioneers of this model theory of modality include prominently Stig Kanger and Saul Kripke. Several others were working in the same area independently and more or less concurrently. Some of the older papers in this collection, especially 'Quantification and Modality' and 'Modes of Modality', serve to clarify some of the main possibilities in the semantics of modal logics in general.

In the last 25 years, the concept of information has played a crucial role in communication theory, so much so that the terms information theory and communication theory are sometimes used almost interchangeably. It seems to us, however, that the notion of information is also destined to render valuable services to the student of induction and probability, of learning and reinforcement, of semantic meaning and deductive inference, as~well as of scientific method in general. The present volume is an attempt to illustrate some of these uses of information concepts. In 'On Semantic Information' Hintikka summarizes some of his and his associates' recent work on information and induction, and comments briefly on its philosophical suggestions. Jamison surveys from the sub­ jectivistic point of view some recent results in 'Bayesian Information Usage'. Rosenkrantz analyzes the information obtained by experimen­ tation from the Bayesian and Neyman-Pearson standpoints, and also from the standpoint of entropy and related concepts. The much-debated principle of total evidence prompts Hilpinen to examine the problem of measuring the information yield of observations in his paper 'On the Information Provided by Observations'. Pietarinen addresses himself to the more general task of evaluating the systematizing ('explanatory') power of hypotheses and theories, a task which quickly leads him to information concepts. Domotor develops a qualitative theory of information and entropy. His paper gives what is probably the first axiomatization of a general qualitative theory of information adequate to guarantee a numerical representation of the standard sort.

The papers and comments published in the present volume represent the proceedings of a research workshop on the grammar and semantics of natural languages held at Stanford University in the fall of 1970. The workshop met first for three days in September and then for a period of two days in November for extended discussion and analysis. The workshop was sponsored by the Committee on Basic Research in Education, which has been funded by the United States Office of Education through a grant to the National Academy of Education and the National Academy of Sciences - National Research Council. We acknowledge with pleasure the sponsorship which made possible a series oflively and stimulating meetings that were both enjoyable and instructive for the three of us, and, we hope, for most of the participants, including a number of local linguists and philosophers who did not contribute papers but actively joined in the discussion. One of the central participants in the workshop was Richard Montague. We record our sense of loss at his tragic death early in 1971, and we dedicate this volume to his memory. None of the papers in the present volume discusses explicitly problems of education. In our view such a discussion is neither necessary nor sufficient for a contribution to basic research in education. There are in fact good reasons why the kind of work reported in the present volume constitutes an important aspect of basic research in education.

As official sponsors of the First International Conference in the History and Philosophy of Science, the two Divisions of the International Union of the History and Philosophy of Science owe a great deal to the University of Jyvliskyla and the 1973 Jyvliskylli Summer Festival for the extra­ ordinarily generous hospitality they provided. But there is an additional debt owed, not simply for the locale but for the very substance of the Conference, to the two Finnish scholars who have jointly authored the present volume. For this volume represents not only the first part of the published proceedings of this First International Conference in the History and Philosophy of Science, but also, most fittingly, the paper that opened the Conference itself. Yet the appropriateness of the paper from which this book has resulted opening the Conference lies far less in the fact that it was a contribution by two Finnish authors to a meeting hosted in Finland than it does to the fact that this paper, and now the present book, comes to grips in an extreme­ ly direct way with the very problem the whole Conference was from the outset designed to treat. Generally put, this problem was to bring to­ gether a number of historians and philosophers of science whose contrib­ uted papers would bear witness to the ways in which the two disciplines can be, and are, of value to each other.
