Rationality of Performance

Abstract

What at first sight seems paradoxical, “rationality of performance”, refers to an extraordinary ability that human beings have, namely to their competence-in-performance that enables them to meet the vicissitudes of life and to negotiate their interests and purposes in dialogic interaction with their fellow beings. The concept of “rationality of performance” requires a change from a logical rationality to an adaptive rationality, which can come to grips with ever-changing activities and the uncertainties of life. To accept such a concept means changing our way of theorizing from the classical to a modern way of theorizing, i.e., moving from reductionism to holism. This paper introduces the Mixed Game Model and outlines basic elements of such a holistic theory that puts human beings at its centre and describes their actions and behaviour by means of principles of probability.
