Free trade, free competition, sustained economic growth, the free movement of peoples -- these were, for Britain at least, the dominant economic aspirations of the nineteenth century. Nor were they entirely irrelevant after the turn of the century. Indeed, one might subscribe to such doctrines without self-deception until the close of World War II. For it was only after the first phase of the postwar recovery in Europe that one could descry the shape of things to come and, in that vision, doubt the relevance of these once-emancipating liberal doctrines to the momentous developments being wrought on our lives by the increasing pace of science and technology. The more salient among these developments are: the unprecedent expansion of the human species having ecological consequences we are only beginning to perceive.
