Professor Insole is Professor of Philosophical Theology and Ethics at the University of Durham, and Professorial Fellow at the Australian Catholic University. He has published extensively on realism and anti-realism, the relationship between theology, metaphysics, and political philosophy, and on the thought of Immanuel Kant. His books include his major study of Kant (Oxford, 2013). Since 2016, his research has moved into a more contemporary and constructive key, engaging with the category of natural theology. He is exploring the possibility of re-conceiving natural theology as a type of negative theology.
Professor Insole presented the 2013 McDonald Lectures (Oxford) in Christian Ethics and Public Life.
Professor Insole is the Lead Investigator for a major five-year programme, called 'Redeeming Autonomy: Agency, Vulnerability, and Relationality', funded and hosted by the Australian Catholic University, with co-investigators Dr David Kirchhoffer (ACU), Professor Jennifer Herdt (Yale), Professor Kristin Heyer (Boston), and Professor Yves De Maeseneer (Leuven). The programme brings together philosophers, theologians, social scientists, historians, anthropologists, policy-makers, political philosophers, lawyers, and literary scholars, in order to investigate the use and misuse of the (ancient, medieval, and modern) concept of rational self-government, in urgent concrete areas of policy, and practice, such as end-of-life legislation, disability, immigration, trauma, transgender rights, and political sovereignty.
