Norbert Wiener and Cybernetical Concept of Time.

摘要

The first chapter of Norbert Wiener's book 'Cybernetics' is entitled 'Newtonian and Bergsonian Time.' This may show how fundamental he considered it to be to study the concept of time that should underlie cybernetics. Wiener emphasizes only the irreversible aspect of time and does not mention the important difference Bergson makes between two kinds of irreversible time. In this second book on cybernetics. 'The Human Use of Human Beings' Wiener makes a more explicit remark about the entropy decreasing tendency of life. I shall discuss the decrease of physical entropy in an open system, and the non-physical entropy. (Author)
