Speaker(s): Professor Jeffrey D. Sachs | In his 2017 Robbins Lectures, Professor Jeffrey D. Sachs will argue for a new Moral Economics built firmly on the foundations of the new moral sciences. The goal of moral economics is to promote wellbeing. A core principle is the cultivation of individual and group virtue to help guide the behavior of both individuals and groups in the global society. Lecture 2. The Hard Problem of Inter-Group Morality. The most difficult moral challenges involve the interaction across groups, whether nation states, private companies, or ethnic groups. In all such cases, there is the deep tendency towards inter-group conflict. The cultivation of group virtue to underpin inter-group peace and cooperation is an especially daunting challenge. The two other lectures that are part of this series are on Monday 13 and Wednesday 15 February.
