The three and a half years of Japanese occupation were the most important of my life. They gave me vivid insights into the behaviour of human beings and human societies, their motivations and impulses. My appreciation of governments, my understanding of power as the vehicle for revolutionary change, would not have been gained without this experience. I saw a whole social system crumble suddenly before an occupying army that was absolutely merciless. The Japanese demanded total obedience and got it from nearly all. They were hated by almost everyone but everyone knew their power to do harm and so everyone adjusted. Those who were slow or reluctant to change and to accept the new masters suffered. They lived on the margins of the new society, their fortunes stagnated or declined and they lost their status. Those who were quick off the mark in assessing the new situation, and swift to take advantage of the new opportunities by making themselves useful to the new masters, made fortunes out of the terrible misfortune that had befallen all in Singapore.
