Judaism and Christianity, the religious traditions most influential on Western civilization, taught that the universe was created by the Word and that human beings were distinguished from all other animals by their use of words. What characterizes our age is a growing reliance on images as our words are being desymbolized. This desymbolization of experience, language, and culture results primarily from what Jacques Ellul has called technique, which has been built up with discipline-based approaches to knowing and doing. It has helped create a new human nature as well as new social forms called mass societies, in which integration propaganda is required to make up the deficits of our highly desymbolized cultures. As a result, life in a mass society defers to science for knowing and to technique for doing, thereby creating a cult of efficiency that is at the root of our economic, social, and environmental crises. How far this desymbolization can go may well turn out to be the decisive issue of the 21st century. (Contains 1 table.)
