Rationality In Action

The study of rationality and practical reason, or rationality in action, has been central to Western intellectual culture. In this invigorating book, John Searle lays out six claims of what he calls the Classical Model of rationality and shows why they are false. He then presents an alternative theory of the role of rationality in thought and action. A central point of Searle's theory is that only irrational actions are directly caused by beliefs and desires—for example, the actions of a person in the grip of an obsession or addiction. In most cases of rational action, there is a gap between the motivating desire and the actual decision making. The traditional name for this gap is "freedom of the will." According to Searle, all rational activity presupposes free will. For rationality is possible only where one has a choice among various rational as well as irrational options. Unlike many philosophical tracts, Rationality in Action invites the reader to apply the author's ideas to everyday life. Searle shows, for example, that contrary to the traditional philosophical view, weakness of will is very common. He also points out the absurdity of the claim that rational decision making always starts from a consistent set of desires. Rational decision making, he argues, is often about choosing between conflicting reasons for action. In fact, humans are distinguished by their ability to be rationally motivated by desire-independent reasons for action. Extending his theory of rationality to the self, Searle shows how rational deliberation presupposes an irreducible notion of the self. He also reveals the idea of free will to be essentially a thesis of how the brain works.

In this book Joseph Heath brings Jürgen Habermas's theory of communicative action into dialogue with the most sophisticated articulation of the instrumental conception of practical rationality-modern rational choice theory. Heath begins with an overview of Habermas's action theory and his critique of decision and game theory. He then offers an alternative to Habermas's use of speech act theory to explain social order and outlines a multidimensional theory of rational action that includes norm-governed action as a specific type. In the second part of the book Heath discusses the more philosophical dimension of Habermas's conception of practical rationality. He criticizes Habermas's attempt to introduce a universalization principle governing moral discourse, as well as his criteria for distinguishing between moral and ethical problems. Heath offers an alternative account of the level of convergence exhibited by moral argumentation, drawing on game-theoretic models to specify the burden of proof that the theory of communicative action and discourse must assume.

This book presents an account of normative practical reasons and the way in which they contribute to the rationality of action. Rather than simply 'counting in favour of' actions, normative reasons play two logically distinct roles: requiring action and justifying action. The distinction between these two roles explains why some reasons do not seem relevant to the rational status of an action unless the agent cares about them, while other reasons retain all their force regardless of the agent's attitude. It also explains why the class of rationally permissible action is wide enough to contain not only all morally required action, but also much selfish and immoral action. The book will appeal to a range of readers interested in practical reason in particular, and moral theory more generally.

Human actions unfold over time, in pursuit of ends that are not fully specified in advance. Rational Powers in Action locates these features of the human condition at the heart of a new theory of instrumental rationality. Where many theories of rational agency focus on instantaneous choices between sharply defined outcomes, treating the temporally extended and partially open-ended character of action as an afterthought, this book argues that the deep structure of instrumental rationality can only be understood if we see how it governs the pursuit of long-term, indeterminate ends. These are ends that cannot be realized through a single momentary action, and whose content leaves partly open what counts as realizing the end. Sergio Tenenbaum argues that we need to focus on temporal duration and the indeterminacy of ends in intentional action, even to explain the rational governance of relatively simple actions. Theories of moment-by-moment preference maximization, or indeed any understanding of instrumental rationality on the basis of momentary mental items, cannot capture the fundamental structure of our instrumentally rational capacities. Tenenbaum provides a new theory of instrumental rationality as rationality in action.

This collection of original essays examines the controversy over and attacks on rationality in the methodologies of the humanities and the physical and social sciences. These essays represent the thinking of a wide variety of philosophers, psychologists, historians, classicists, and economists about the role of rationality in thought and action. Reflecting the differing perspectives of their authors' disciplines, as well as the centrality of rationality to those disciplines, they are important additions to a debate that has been going on for some twenty years. Beginning with an introductory essay in which K.D. Irani covers the various ways in which rationality can be approached, the body of the book is divided into five sections dealing with various aspects of the issue. Respectively, they are concerned with rationality as it relates to ethical and social thought and action; general scientific thought and the particular disciplines of economics, history, and law; the analytic and hermenutic approaches to communications and learning; and the contrasting classical traditions of ancient Greece and China. In the final section, two differing theories concerning the nature of rationality itself are presented. A list of suggested further readings completes the volume.

Risk as we now know it is a wholly new phenomenon, the by-product of our ever more complex and powerful technologies. In business, policy making, and in everyday life, it demands a new way of looking at technological and environmental uncertainty. In this definitive volume, four of the world's leading risk researchers present a fundamental critique of the prevailing approaches to understanding and managing risk - the 'rational actor paradigm'. They show how risk studies must incorporate the competing interests, values, and rationalities of those involved and find a balance of trust and acceptable risk. Their work points to a comprehensive and significant new theory of risk and uncertainty and of the decision making process they require. The implications for social, political, and environmental theory and practice are enormous.

The evolution of a set of fields—including operations research and systems analysis—intended to improve policymaking and explore the nature of rational decision-making. During World War II, the Allied military forces faced severe problems integrating equipment, tactics, and logistics into successful combat operations. To help confront these problems, scientists and engineers developed new means of studying which equipment designs would best meet the military's requirements and how the military could best use the equipment it had on hand. By 1941 they had also begun to gather and analyze data from combat operations to improve military leaders' ordinary planning activities. In Rational Action, William Thomas details these developments, and how they gave rise during the 1950s to a constellation of influential new fields—which he terms the “sciences of policy”—that included operations research, management science, systems analysis, and decision theory. Proponents of these new sciences embraced a variety of agendas. Some aimed to improve policymaking directly, while others theorized about how one decision could be considered more rational than another. Their work spanned systems engineering, applied mathematics, nuclear strategy, and the philosophy of science, and it found new niches in universities, in businesses, and at think tanks such as the RAND Corporation. The sciences of policy also took a prominent place in epic narratives told about the relationships among science, state, and society in an intellectual culture preoccupied with how technology and reason would shape the future. Thomas follows all these threads to illuminate and make new sense of the intricate relationships among scientific analysis, policymaking procedure, and institutional legitimacy at a crucial moment in British and American history.
