Complexity and Emergence: Proceedings of the Annual Meeting of the International Academy of the Philosophy of Science. Bergamo, Italy 9-13 May 2001

Complexity has become a central topic in certain sectors of theoretical physics and chemistry (for example, in connection with nonlinearity and deterministic chaos). Also, mathematical measurements of complexity and formal characterizations of this notion have been proposed. The question of how complex systems can show properties that are different from those of their constituent parts has nurtured philosophical debates about emergence and reductionism, which are particularly important in the study of the relationship between physics, chemistry, biology and psychology. This text offers a presentation of those topics through an interdisciplinary approach in which the philosophy of science and the specialized topics of certain sciences are put in a dialogue.
