A graduate economists need to be under the impression of their future role in society, the awe-inspiring diversity and complexity of reality and the opportunities and limitations of the economic sciences to deal with real-world problems. The power that economics has in shaping policies and decisions comes with a lot of responsibility. Economic policies and decisions have deep and profound impacts on the wellbeing of individual people, on society and the earth we live in. A sense of what scientific abstraction means and a proficiency in the tools and models that comes with it is necessary, but not sufficient. The pervasive economic and ecological crises emphasizes again how important it is that graduate economists need to have a well-developed sense of the moral philosophies that guide ethically responsible choices in society and to know how and when to act to the benefit of society and the earth we share.
