Reasoning about Rational Agents


Book Description

This book focuses on the belief-desire-intention (BDI) model of rational agents, which recognizes the primacy of beliefs, desires, and intentions in rational action. One goal of modern computer science is to engineer computer programs that can act as autonomous, rational agents; software that can independently make good decisions about what actions to perform on our behalf and execute those actions. Applications range from small programs that intelligently search the Web buying and selling goods via electronic commerce, to autonomous space probes. This book focuses on the belief-desire-intention (BDI) model of rational agents, which recognizes the primacy of beliefs, desires, and intentions in rational action. The BDI model has three distinct strengths: an underlying philosophy based on practical reasoning in humans, a software architecture that is implementable in real systems, and a family of logics that support a formal theory of rational agency.The book introduces a BDI logic called LORA (Logic of Rational Agents). In addition to the BDI component, LORA contains a temporal component, which allows one to represent the dynamics of how agents and their environments change over time, and an action component, which allows one to represent the actions that agents perform and the effects of the actions. The book shows how LORA can be used to capture many components of a theory of rational agency, including such notions as communication and cooperation.

Foundations of Rational Agency


Book Description

This volume represents an advanced, comprehensive state-of-the-art survey of the field of rational agency as it stands today. It covers the philosophical foundations of rational agency, logical and decision-theoretic approaches to rational agency, multi-agent aspects of rational agency and a number of approaches to programming rational agents. It will be of interest to researchers in logic, mainstream computer science, the philosophy of rational action and agency, and economics.




Common Sense, Reasoning, & Rationality


Book Description

While common sense and rationality have often been viewed as two distinct features in a unified cognitive map, this volume engages with this notion and comes up with novel and often paradoxical views of this relationship.




Collective Rationality and Collective Reasoning


Book Description

"This book examines the issue of rational cooperation, especially cooperation between people with conflicting moral commitments. The first part considers how the two main aspects of cooperation - the choice by a group of a particular cooperative scheme and the decision by each member to contribute to that scheme - can be understood as guided by reason. The second part explores how the activity of reasoning itself can take a cooperative form. The book is distinctive in offering an account of what people can accomplish by reasoning together, of the role of deliberation in democratic decision making, and of the negotiation of the proper use of concepts. Presenting for the first time a detailed analysis of the general problem of cooperation and collective reasoning between people with different moral commitments, this book will be of particular interest to philosophers of the social sciences and to students in political science, sociology and economics." --Cambridge Press.




Practical Reasoning and Ethical Decision


Book Description

Presenting the most comprehensive and lucid account of the topic currently available, Robert Audi's "Practical Reasoning and Ethical Decision" is essential reading for anyone interested in the role of reason in ethics or the nature of human action. The first part of the book is a detailed critical overview of the influential theories of practical reasoning found in Aristotle, Hume and Kant, whilst the second part examines practical reasoning in the light of important topics in moral psychology - weakness of will, self-deception, rationalization and others. In the third part, Audi describes the role of moral principles in practical reasoning and clarifies the way practical reasoning underlies ethical decisions. He formulates a comprehensive set of concrete ethical principles, explains how they apply to reasoning about what to do, and shows how practical reasoning guides moral conduct.




Reasons Without Persons


Book Description

Brian Hedden defends a radical view about rationality, personal identity, and time. He argues that what it is rational to do should not depend on your past beliefs or actions, which are not part of your current perspective on the world. His impersonal approach holds that what rationality demands of you is solely determined by your evidence.




Reasoning of State


Book Description

Challenges the assumption of the rationality of foreign policy makers in international relations, showing how leaders systematically vary in the rationality of their thinking.




Knowledge Representation and Reasoning


Book Description

Knowledge representation is at the very core of a radical idea for understanding intelligence. This book talks about the central concepts of knowledge representation developed over the years. It is suitable for researchers and practitioners in database management, information retrieval, object-oriented systems and artificial intelligence.




Unsettled Thoughts


Book Description

How should thinkers cope with uncertainty? What makes their degrees of belief rational, and how should they reason about uncertain matters? In epistemology, recent research has attempted to answer these questions by developing formal models of ideally rational credences. However, we know from psychological research that perfect rationality is unattainable for human thinkers--and so this raises the question of how rational ideals can apply to human thinkers. A popular reply is that the more a thinker's imperfectly rational credences approximate compliance with norms of ideal rationality, the better. But what exactly does this mean? Why is it better to be less irrational, if we can't ever be completely rational? And what does being closer to ideally rational amount to? If ideal models of rationality are supposed to help us understand the rationality of human, imperfect thinkers, we need answers to these questions. Unsettled Thoughts breaks new ground in the study of rationality in providing these answers: we can explain why it's better to be less irrational, because less irrational degrees of belief are generally more accurate and better at guiding our actions. Moreover, the way in which approximating ideal rationality is beneficial can be made formally precise by using a variety of distance measures that track the benefits of being more rational.
