Overview: Observes that over the centuries Western civilization has regularly shifted its conception of the nature of truth. The series closes with host James Burke's remarkably prescient assessment of the role in which modern computer networks are beginning to now play in shaping man's current conception of his reality as well as how they may well define the fundamental nature of all future human interaction. And while his message is ultimately a positive one, it is tempered with the warning that while the promise of the computer may indeed provide a framework for a future anarchism where human freedom is nourished and where every individual conception of reality is a valid one, it could conversely become of tool of totalitarian repression and conformity.
