Ziauddin Sardar shows that thinking and speculating about the future has always been a part of human history, but exploring the futures in a systematic and scientific way is a recent phenomenon. What is known variously as 'futures studies', 'futurology' or 'foresight' only emerged as a discipline during the last few decades. The study of the future, however, is not only about 'predicting' or 'forecasting' the future, which is always a perilous exercise. It is also about appreciating the potentials and possibilities, as well as risks and threats, lurking over the horizon.
