[Bioethics destiny]

The paper is about the links between ethics and science, at a time (1974-2014) when the life sciences expanded rapidly. First (1974-1994), the development of a principlist ethics, set out by philosophers, sustained the research, and the scientists, expected to behave responsibly, felt like they could easily converge towards impeccable and consensual solutions to any problem arising from scientific innovations. Later on (1994-2014), however, while yielding ground to social sciences and ground work, bioethics took an empirical turn; then it became clear that behaving responsibly was compatible with a plurality of divergent normative convictions. Ethics crumbled. Local or national policies restored order, so-called bioethical laws short-circuited ethical reflection. And far from being respected as the wise men, apt to recommend the very best solutions to problems raised by new scientific advances, researchers happened to be deemed irresponsible, as some of them were suspected of lacking intellectual integrity.
