The University of Groningen will be hosting its second annual winter school in Philosophy, Politics and Economics (PPE) on January 29-30, 2018. The theme of this year’s winter school is “Uncertainty, Conflict and Disagreement.” From the perspective of the various disciplines that make up PPE, we will explore questions like: How do we design mutually acceptable social institutions and public policies when we disagree fundamentally with each other about basic empirical facts and questions of justice? How can we be responsible stewards of the future given the extreme difficulty of predicting the long-run effects of our present choices? How do we identify fair compromises between conflicting values, and how far should we be willing to compromise our values in order to preserve a shared moral and political community? Students will have the opportunity to learn from University of Groningen faculty whose research bears on these questions. This year’s instructors include Francesca Giardini, Leah Henderson, Frank Hindriks, Jan Albert van Laar, Chiara Lisciandra, Andreas Schmidt, and Allard Tamminga.
