Abstract
No other area of human activity than science and technology has achieved as much intellectually and in terms of technical innovation. Nevertheless, despite these unchallengeable advances, science and technology do not inevitably lead to moral and social progress for humanity: The dreams of reason may also imply nightmares. As this century draws to a close, the most crucial change is occurring in science and technology policy, altering in particular the special status that science has enjoyed since World War II, affecting the conditions under which academic research is carried out, compelling to more collaborative international research efforts and leading at the same time to growing ethical issues at the forefront of choices in relation to the environment, to the new technologies, and even to scientific research per se. Future generations will observe the twists and turns of history partly because of and partly in spite of these choices.
