[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.

[Non-medical applications for brain MRI: Ethical considerations].

Introduction: The recent neuroimaging techniques offer the possibility to better understand complex cognitive processes that are involved in mental disorders and thus have become cornerstone tools for research in psychiatry. The performances of functional magnetic resonance imaging are not limited to medical research and are used in non-medical fields. These recent applications represent new challenges for bioethics.

The place of words and numbers in psychiatric research.

In recent decades, there has been widespread debate in the human and social sciences regarding the compatibility and the relative merits of quantitative and qualitative approaches in research. In psychiatry, depending on disciplines and traditions, objects of study can be represented either in words or using two types of mathematization. In the latter case, the use of mathematics in psychiatry is most often only local, as opposed to global as in the case of classical mechanics.
