Stephen Purdey is a Lecturer at the University of Toronto, Canada. After several years working in the private sector, in Canadian federal politics, and with various NGOs, his current academic work focuses on the origins and environmental impact of the ubiquitous political commitment to economic growth. Of particular interest are the normative underpinnings of that commitment. Thematic to Purdey's research is the notion that the rapidly changing relationship between human society and Earth cannot be effectively managed without revitalizing the moral discourse that provides meaning and direction to those changes.
