The third volume in a series designed to clarify the issues relating to the concept of information aims to help develop a science of information and study a pattern of interrelated phenomena which extends through all of nature.

Covers a great breadth of intellectual territory, providing sufficient depth to give credibility to the numerous new ideas presented.
