PREFACE A couple of decades aga one could speak: of a boom in the field of philosophy of action, but in recent years this field has seemingly been leading a more quiet life. Nevertheless, important developments have taken place not only in the traditional philosophical and logical problems of action but also in the computa tional aspects of action as weIl as in the new field of the theory of social (especially multi-agent) action. To mention an example from outside philoso phy, in artificial intelligence problems of coordination and cooperation have recently acquired enormous importance and have led to much interesting new theoretical work as weIl as to practical applications. Contemporary Action Theory is a two-volume work which attempts a comprehensive assessment of the current state of the art by leading researchers. We believe that such an assessment is warranted in view of the most recent developments in action theory - especially as no other similar current work is available. The two volumes of Contemporary Action Theory are entitled Individual Action (Vol. I) and Social Action (Vol. 11). Although there is some overlap between the fields covered by the two volumes, the first basically concerns the logic and philosophy of single-agent actions while all the papers in the second one are concerned with social action. Volume I covers standard questions in the philosophy of single-agent action, while Volume 11 is concerned with the social aspects of human action, especially with multi-agent action. Volume 11 contains papers not only by philosophers but also by researchers working in artificial intelligence (or in closely related fields). The anthology was not intended to cover contemporary action theory systematically, but in fact it ends up doing almost that. Thus practically all central questions dealt with by traditional philosophy and theory of action are discussed in the papers included here. This project has been a genuinely joint one, and the order in which the authors are listed has only alphabetical significance. Our project would not have been possible without invaluable support by the Academy of Finland which facilitated not only Tuomela's contribution to the months-Iong editing process, especially to that of volume 2, but also the practicalities of the process includ ing the translation of G.H. von Wright's paper and the preparation ofthe index. We are grateful to all our contributors for sharing with us the insight of their ongoing research. We also extend our thanks to Mrs. Auli Kaipainen. Her work was supported by Kluwer Academic Publishers, to whom we are grateful for accepting our volumes to the series Synthese Library. Without her excellent v G. Holmström-Hintikka anti R.

Ordinary people as weH as specialists in fields as diverse as philosophers, psychologists, lawyers and theologians all take deep interest in the explanation and understanding of actions. A layperson might simply want to understand why someone did what she did. But so do lawyers and psychiatrists also - although for different reasons and with certain purposes in mind. In the contem porary philosophical literature on action theory beginning in the fifties serious developments have taken place in this particular area. Influential in this regard has been Georg Henrik von Wright whose Explanation and Understanding (1971) has caused a flow of discussions and brought about numerous artieles. Significantly enough his paper in this very volume is entitled "Explanation and Understanding in Action". He is also subject to a comparison with Collingwood in Rex Martin's paper "von Wright and CoHingwood on Causation and the Explanation of Human Action". What are actions? How can we understand actions? What causes people's actions? A causal explanation is not easy to come up with, nor is it usually a matter of one single explanation. "Metaphysical Foundations of Action Explanation" by Ausonio Marras and "Reasons as Causes for Action" by George Wilson are good examples of the subtleties we are dealing with even in the most basic matters, the causes for our actions. Other aspects of the explanation of human action are dealt with in the various writings on action logic, in particular the logic of individual action. In this regard several famous logicians have forcefully developed far-going theories on single-agent action. Be it enough here to mention only a few representatives. Among others, Nuel Belnap, Brian CheHas, Stig Kanger, Ingmar Pörn, Krister Segerberg, Georg Henrik von Wright and Lennart Äqvist have all in a major way contributed to the development of this subarea of action theory. In his paper "On States, Actions, Omissions and Norms" Risto Hilpinen helps us to understand some of the developments in action logic and also to put these things into perspective with regard to other modalities, in particular to deontic concepts. One instantiation of the Fenno-Scandian tradition (Kanger Lindahl-Pörn) mentioned by Hilpinen is Ghita Holmström-Hintikka's further developments of her action theory based on the tripartition of agent causation. The basic elements, ineluding actions are conditions (states of affairs) as they are in Kanger' s theory. Activity, passivity, competence, practical reason, all these concepts touch upon central features in human action, features which have a bearing on ix G. Holmström-Hintikka and R. Tuomela (eds.), Contemporary Action Theory. Vol. I, ix-xvii. x INTRODUCTION people's health and weH-being as weH as to their social and legal behaviour. All these matters are discussed in the logic group of papers appearing below. When behaviour is being evaluated, praise and blame will depend, not only on results accomplished or not accomplished, but also on the intentions behind the actions. This topic can be dealt with from a theoretical point of view as by Robert Audi or from a "practical" causal point of view as by Myles Brand. Freedom of Action and Freedom of the Will are classical and yet always inspiring topics. It seems as if there is always something new and interesting to be said. These two topics support the still more specialized topics on mental action and the Causal Theory of Action versus the Agent Causation Theory, not to mention cognitive trying. A SHORT PRESENTATION OF THE PAPERS IN VOLUME I 1. An important type of explanations of action makes reference to reasons, says Georg Henrik von Wright in "Explanation and Understanding of Actions". The author of the paper calls them "understanding explanations. " Often there are several reasons for one and the same action - and possibly also reasons against performing it. The fact that something is a reason for an action does not necessarily mean that the action is performed for that reason. One must, in other words, distinguish between the existence and the efficacy of reasons for actions. This raises the question of the veracity of a suggested explanation when the action is correct1y identified and the reasons for its performance are known. The author defends a thesis that the efficacious reasons for an action are those in the light of which we understand the action. The "tie" between the action and the (efficacious) reason(s) is thus created by the act of understand ing. When there is disagreement between the self-understanding of the agent and an outside ob server, the latter may sometimes succeed in "converting" the former to a new understanding of his motives. The nature of such "conver sions" is discussed in the paper, and it is maintained that neither the agent nor the outsider can claim an exclusive right to authority in the question which is the correct explanation. The "criterion of truth" of the explanation is consensus in the understanding of the action. It cannot be taken for granted that such agreement of opinion can in all cases be attained even "in principle." 2. In "von Wright and CoHingwood on Causation and the Explanation of Human Action" Rex Martin makes comparisons between the two philosophers. Section one of this paper is concemed with setting out the views of Colling wood and von Wright on the explanation of action. Here a single main model or schema for the explanation of actions is identified (that is, for explanations of actions by reference to reasons - to certain thoughts and motivations of the agent). This model provides the root of both von Wright's notion of practical inference and Collingwood's idea of re-enactment. In this first section the
