Contemporary Action Theory, Volume I (Individual Action) is concerned with topics in philosophical action theory such as reasons and causes of action, intentions, freedom of will and of action, omissions and norms in legal and ethical contexts, as well as activity, passivity and competence from medical points of view. Cognitive trying, freedom of the will and agent causation are challenges in the discussion on computers in action. The Volume consists of contributions by leading experts in the field written specifically for this volume. No comparable volume currently exists.

This collection celebrates the centenary of the Lvov-Warsaw school, established by Kazimierz Twardowski in Lvov in 1895. This school belongs to analytic philosophy and successfully worked in all branches of philosophy. The Warsaw school of logic became perhaps the most important part of Twardowski's heritage. Lesniewski, Lukasiewicz and Tarski, leading Polish logicians, achieved results which essentially influenced the development of contemporary logic. A close connection of logic and philosophy was a typical feature of the Lvov-Warsaw school. The papers included in the collection deal with all directions of research undertaken by Polish analytic philosophers. Special attention is paid to logic and comparisons with other philosophical movements, particularly with Brentanism, which was one of the sources of the Lvov-Warsaw school.

We act for reasons. But, it is sometimes claimed, the mental states and events that make up reasons, are not sufficient conditions of actions. Reasons never make actions happen. We- as agents (persons, selves, subjects) - make our actions happen. Actions are done by us, not elicited by reasons. The present essay is an attempt to understand this concept of agent causality. Who -~ or what - is an agent ? And how - in virtue of what - does an agent do things, or refrain from doing them? The first chapter deals with problems in the theory of action that seem to require the assumption that actions are controlled by agents. Chapters two and three then review and discuss theories of agent cau sality. Chapters four and five make up the central parts of the essay in which my own solution is put forth, and chapter six presents some data that seem to support this view. Chapter seven discusses how the theory can be reconciled with neuro-physiological facts. And in the last two chapters the theory is confronted with conflicting viewpoints and phe nomena. Daniel Robinson and Richard Swinburne took time to read parts of the manuscript in draft form. Though they disagree with my main viewpoints on the nature of the self, their conunents were very helpful. I hereby thank them both.

Believing the wrong thing can have drastic consequences. The question of when a person is not only ill-guided, but genuinely at fault for holding a particular belief goes to the root of our understanding of such notions as criminal negligence and moral responsibility. This book explores the conditions under which someone may be deemed blameworthy for holding a particular belief, drawing on contemporary epistemology, ethics and legal scholarship.

In his writings around 1930, Wittgenstein relates his philosophy in different ways to the idea of phenomenology. He indicates that his main philosophical project had earlier been the construction of a purely phenomenological language, and even after having given up this project he believed that "the world we live in is the world of sense-data,,,l that is, of phenomenological objects. However, a problem is posed by the fact that he does not appear ever to have given a full, explicit account of what he means by his 'phenomenology', 'phenomenological language', or 'phenomenological problems'. In this book, I have tried to unravel the nature of Wittgenstein's phenomenology and to examine its importance for his entire work in philosophy. Phenomenology can be characterized as philosophy whose primary concern is what is immediately given in one's experience. This 'immediately given' is not merely impressions inside one's mind, but includes also the part of objective reality that impinges upon one's consciousness. Thus, an aim of phenomenological enterprise is to grasp this objective reality by attending to immediate experience. Husserl's phenomenology is in fact a case in point.

Intentionality is one of the most frequently discussed topics in contemporary phenomenology and analytic philosophy. This book investigates intentionality from the point of view of intentional objects. According to the classical approach to this concept, whatever can be consciously experienced is regarded as an intentional object. Thus, not only ordinary existing individuals but also various kinds of non-existents and non-individuals are considered as intentional (including such bizarre entities as quantifier objects: `some dog', `every dog'). Alexius Meinong, an Austrian philosopher, is particularly well-known as the `inventor' of an abundant ontology of objects among which even incomplete and impossible ones, like `the round square', find their place. Drawing inspirations from Meinong's ideas, the author develops a simple logic of intentional objects, M-logic. M-logic closely resembles classical first-order logic and, as opposed to the formally complicated contemporary theories of non-existent objects, it is much more friendly in apprehending and applications. However, despite this resemblance, the ontological content of M-logic far exceeds that of classical logic. In this book formal investigations are intertwined with philosophical analyses. On the one hand, M-logic is used as a tool for investigating formal features of intentional objects. On the other hand, the study of intentionality phenomena suggests further ways of extending and modifying M-logic. Audience: The book is addressed to logicians, cognitive scientists, philosophers of language and metaphysics with either a phenomenological or an analytic background.
