This quote is from Alvin Toffler's "Previews and Premises", Pan Books Ltd, 1984 ISBN 0 330 28421 5. Although it is less well known than many of his other books it has got two things going for it. One, it's very slim compared to most of his other books. Two, in many ways it is much sharper than some of his other writing because it is in the form of a dialogue between him and the left-leaning South End Press.
