I work at the interface of social and political theory. In terms of social theory my interests are in historical epistemology, neo-biological approaches to society, philosophical anthropology, cultural theory and aesthetics, and the philosophy of social science. In political theory my interests centre on liberalism (and anti-liberalism) and on populism. My books are Aspects of Enlightenment: social theory and the ethics of truth (1998), The Structure of Modern Cultural Theory (2008) and, with Nikolas Rose, Questioning Humanity; being human in a posthuman age (2024).
