Gerrit Schaafsma is a PhD researcher at the Department of Philosophy at the University of Amsterdam. His research is about climate change and civil disobedience with an interest in both the theory and the practice of principled law-breaking. Working in the public philosophy tradition of James Tully, his work is informed by those engaging directly in disobedient actions while also drawing on the academic debates that have shaped public ideas about what civil disobedience is, and of its role in a democratic society. His other research interests include environmental philosophy (especially climate justice), global justice and liberal egalitarian theories of justice. His previous work has focused on property ownership and governance: Rawlsian property-owning democracy, the work of James Meade, and the work of Henry George (in particular, ideas about single value land taxes and economic methods for reducing speculation and decreasing wealth inequality).
