New edition of a systematic analysis of past, present and future technological innovations and their relation to significant social issues. It discusses three tools useful for investigating the relationship of technology to society and for predicting cultural trends based on such the general categorical model, noting specific areas of interaction between society and technology; the PERSIA concept, based on a scheme for studying historical models; and the anthropological model, which relies on the same basic divisions as anthropology uses for studying cultures.
