Why good work in philosophical bioethics often looks strange

Papers in philosophical bioethics often discuss unrealistic scenarios and defend controversial views. Why is that, and what is this kind of work good for? My aim in the first part of this paper is to specify how philosophical bioethics relates to other types of work in bioethics, and to explain the role of the unrealistic scenarios and the controversial views. In the second part, I propose three strategies for doing research in philosophical bioethics that makes a valuable contribution to the bioethics community at large.
