The new series aims to closely combine ethics and empiricism: It is intended to address concrete ethical questions that are also discussed in the broader public, to examine the empirical results from the relevant empirical sciences on these questions, and to discuss philosophical, theological, legal, etc. issues in a more comprehensive way. Possible topics are: Xenotransplantation, euthanasia and assisted suicide, organ donation, child ethics, animal ethics, etc. Particularly in view of the new developments in molecular biology, questions about the significance of nature for ethical arguments and for bioethical debates are becoming increasingly urgent and relevant, which is also reflected in the work of ethics committees. The study also examines how empirical questions and the work of ethics commissions influence ethical theory formation.
