That age may finally have come. Biotech, so it seems, represents both the pinnacle of modern science and its eclipse, the power and the inability of reason. It vindicates admirably the Baconian formula that knowledge is power while illustrating at the same time the loss of moral orientation. The enormous advances we have made in science and technology are quite obviously not matched by a similar progress in our moral awareness that would enable us to put our scientific knowledge in the service of a shared vision of 'the good life'. It needs the combined efforts of all concerned, including scientists, policy makers, social planners and philosophers to take up the challenge which has begun to change nature's course and to impact our lives more than anything before in the history of mankind. Nietzsche's sketch of the ideological implications of modern science has been etched out with crude tools (he called this proudly 'to philosophize with a hammer'); it can, however, serve as a vivid reminder of what is at stake.
