Unexpected discoveries in nonequilibrium physics and nonlinear dynamics are changing our understanding of complex phenomena. Recent research has revealed fundamental new properties of matter in far-from-equilibrium conditions, and the prevalence of instability-where small changes in initial conditions may lead to amplified effects.
In this book, after discussing the fundamental problems of current science and other philosophic concepts, beginning with controversies between Heraclitus and Parmenides, Ilya Prigogine launches into a message of great hope: the future has not been determined. Contrary to globalisation and the apparent contemporary mass culture society, individual behaviour is beginning to increasingly become the key factor which governs the evolution of both the world and society as a whole. It is a message that challenges existing widespread views, implicitly or (...) explicitly, through mass communication; moreover the importance of the individual's actions implies a reflection of each person on the responsibilities that each one assumes when taking or acting upon a decision. This responsibility is associated with the freedom of thought as well as a critical analysis of fashions, customs, preconceived ideas, and ideologies, externally imposed: exactly contrary to the ideas of those who wish us to be?perfect consumers? in a world dominated only by monetary wealth.Challenging this drive towards the elimination of freedom of thought in the individual is now imperative if we are to save man and his planet from catastrophe, which seems to be ever imminent and irreversible.This last book of Ilya Prigogine provides a small, disputable, but nonetheless valuable contribution towards that end.

The role of passion and more generally irrational elements in processing knowledge are discussed. This seems to be a paradox, as science by definition is beyond passion. At the same time science is the expression of a culture. This paradox is examined through the experience and work of crucial figures in physics such as Newton and Einstein. Science is a dialogue between man and nature: part of the search for the transcendental which is common to many cultural activities: art, music, (...) literature. Our time is one of expectation, anxiety, and bifurcation. Far from there being an ?end? of science, our period will see the birth of a new vision, a new science whose cornerstone encloses the arrow of time: a science that makes us and our creativity the expression of a fundamental trend in the universe.

The Norbert Wiener Memorial Gold Medal address delivered by the Nobel Laureate recipient. Considers Norbert Wiener and the idea of contingence. Refers to Wiener's book The Human Use of Human Beings and in particular to the preface entitled "The idea of a contingent universe" and to the epilogue of the book by Rosenblith. This raises the question faced by Wiener: how to reconcile a deterministic world à la Newton with the intrinsically probabilistic universe of Gibbs, the relativistic universe of Einstein (...) and the Heisenberg uncertainty principle? Notes the parallelism among the questions Wiener is asking with the ones to which the Gold Medallist has devoted most of his scientific life. Presents a different point of view, as a tribute to the visionary ideas developed by Wiener. Discusses the "new physics" and the problems facing physics today, at the end of the twentieth century.
