The four main essays in this volume investigate new sectors of the theory of decision, preference, act-characteristics, and action analysis. Herbert A. Simon applies tools developed in the theory of decision-making to the logic of action, and thereby develops a novel concept of heuristic power. Adapting ideas from utility and decision theory, Nicholas Rescher proposes a logic of preference by which conflicting theories proposed by G. H. von Wright, R. M. Chisholm, and others can be systematized. Donald Davidson discusses difficulties in specifying the structure of action sentences to elucidate how their meaning depends on that structure. G. H. von Wright devises a method for describing each "state of the world" that results from an action, in a revision of his own earlier work. Additionally, a study of the logic of norms by Alan Ross Anderson is presented as an appendix, along with an appendix by Rescher outlining the aspects of action.

"[This book] proposes new foundations for the Bayesian principle of rational action, and goes on to develop a new logic of desirability and probabtility."—Frederic Schick, Journal of Philosophy

Congress regularly enacts laws that benefit particular groups or localities while imposing costs on everyone else. Sometimes, however, Congress breaks free of such parochial concerns and enacts bills that serve the general public, not just special interest groups. In this important and original book, R. Douglas Arnold offers a theory that explains not only why special interests frequently triumph but also why the general public sometimes wins. By showing how legislative leaders build coalitions for both types of programs, he illuminates recent legislative decisions in such areas as economic, tax, and energy policy. Arnold's theory of policy making rests on a reinterpretation of the relationship between legislators' actions and their constituents' policy preferences. Most scholars explore the impact that citizens' existing policy preferences have on legislators' decisions. They ignore citizens who have no opinions because they assume that uninformed citizens cannot possibly affect legislators' choices. Arnold examines the influence of citizens' potential preferences, however, and argues that legislators also respond to these preferences in order to avoid future electoral problems. He shows how legislators estimate the political consequences of their voting decisions, taking into account both the existing preferences of attentive citizens and the potential preferences of inattentive citizens. He then analyzes how coalition leaders manipulate the legislative situation in order to make it attractive for legislators to support a general interest bill.

We respect Herbert A. Simon as an established leader of empirical and logical analysis in the human sciences while we happily think of him as also the loner; of course he works with many colleagues but none can match him. He has been writing fruitfully and steadily for four decades in many fields, among them psychology, logic, decision theory, economics, computer science, management, production engineering, information and control theory, operations research, confirmation theory, and we must have omitted several. With all of them, he is at once the technical scientist and the philosophical critic and analyst. When writing of decisions and actions, he is at the interface of philosophy of science, decision theory, philosophy of the specific social sciences, and inventory theory (itself, for him, at the interface of economic theory, production engineering and information theory). When writing on causality, he is at the interface of methodology, metaphysics, logic and philosophy of physics, systems theory, and so on. Not that the interdisciplinary is his orthodoxy; we are delighted that he has chosen to include in this book both his early and little-appreciated treatment of straightforward philosophy of physics - the axioms of Newtonian mechanics, and also his fine papers on pure confirmation theory.
