Professor Göran Hermerén, Chair of the European Group on Ethics and Professor of Medical Ethics, University of Lund, delivered his lecture on 7th May 2008 at the Royal Society in London. The ranking of values as a basis for ethical decision making The Nuffield Council on Bioethics bases the conclusions of its reports on ethical principles in combination with the best scientific evidence available. In this lecture, the internationally renowned philosopher Professor Göran Hermerén argued that these ethical principles have to be based on values of various kinds, and that the challenge is not only to clarify the meaning and application of these values but also to rank them in order of importance. He used the current debate on interspecies embryo research to illustrate his approach. Goran Hermeren small
