It seems important that the social value factor be more generally recognized as a powerful causal agent in its own right and something to be dealt with directly as such. No more critical task can be projected for the 1970s than that of seeking for civilized society a new, elevated set of value guidelines more suited to man's expanded numbers and new powers over nature, a frame of reference for value priorities that will act to secure and conserve our world instead of destroying it.
