A spate of recent attacks on the rationality assumption in economic theory is noticed. Some of these attacks are fresh and, in many ways, original, but the central ideas underlying them are not new. They appear to have been provoked by the direction in which much of mainstream economics has been moving in recent years. On the other hand, it is suggested here, certain developments in contemporary economics, associated particularly with the revival of interest in the Austrian paradigm, offer afresh (...) understanding of the way in which the rationality assumption, its role in economics properly understood, is able to meet these old?new attacks.

In this important volume Habermas outlines the views which form the basis of his critical theory of modern societies. The volume comprises five interlocking essays, which together define the contours of his theory of communication and of his substantive account of social change. ′What is Universal Pragmatics?′ is the best available statement of Habermas′s programme for a theoryof communication based on the analysis of speech acts. In the following two essays Habermas draws on the work of Kohlberg and others to (...) develop a distinctive account of moral consciousness and normative structures. ′Toward a Reconstruction of historical Materialsim′ takes these issues further, offering a wide–ranging reconstruction of Marx′s historical materialsim understood as a theory of social evolution. The final essay focuses on the question of legitimacy and on the legitimation problems faced by modern states. This book is essential reading for anyone concerned with the key questions of social and political theory today. (shrink)

Because of the difficulty posed by the contrast between the search for truth and truth itself, Michael Polanyi believes that we must alter the foundation of epistemology to include as essential to the very nature of mind, the kind of groping that constitutes the recognition of a problem. This collection of essays, assembled by Marjorie Grene, exemplifies the development of Polanyi's theory of knowledge which was first presented in Science, Faith, and Society and later systematized in Personal Knowledge. Polanyi believes (...) that the dilemma of the modern mind arises from the peculiar relation between the positivist claim for total objectivity in scientific knowledge and the unprecedented moral dynamism characterizing the social and political aspirations of the last century. The first part of Knowing and Being deals with this theme. Part two develops Polanyi's idea that centralization is incompatible with the life of science as well as his views on the role of tradition and authority in science. The essays on tacit knowing in Part Three proceed directly from his preoccupation with the nature of scientific discovery and reveal a pervasive substructure of all intelligent behavior. Polanyi believes that all knowing involves movement from internal clues to external evidence. Therefore, to explain the process of knowing, we must develop a theory of the nature of living things in general, including an account of that aspect of living things we call "mind." Part Four elaborates upon this theme. (shrink)

In this 1974 book a practising scientist and gifted expositor sets forth an exciting point of view on the nature of science and how it works.

The author of The Death and Life of Great American Cities looks at business fraud and criminal enterprise, overextended government farm subsidies and zealous transit police, to show what happens when the moral systems of commerce collide with those of politics.

The 'Evolution of Cooperation' addresses a simple yet age-old question; If living things evolve through competition, how can cooperation ever emerge? Despite the abundant evidence of cooperation all around us, there existed no purely naturalistic answer to this question until 1979, when Robert Axelrod famously ran a computer tournament featuring a standard game-theory exercise called The Prisoner's Dilemma. To everyone's surprise, the program that won the tournament, named Tit for Tat, was not only the simplest but the most "cooperative" entrant. (...) This unexpected victory proved that cooperation - one might even say altruism - is mathematically possible and therefore needs no hidden hand or divine agent to create and sustain it. A great roadblock to the understanding of all sorts of behavior was at last removed. The updated edition includes an extensive new chapter on cooperation in cancer cells and among terrorist organizations. (shrink)
