Book excerpt: This book addresses a world-wide audience with reference to a global problem: how the PhD can serve the planet. It examines the role of the PhD, in and of itself, and, as representative of research, the university and evidence-based knowledge, in relation to global crisis and the future of humanity. As such, it speaks to the scholar, the teacher, the policy-maker and the administrator concerned with the role of higher education’s highest award at a time of great global crisis. The approach is critical in that it offers diverse views on these issues and does not seek to privilege one single school of thought. The collected articles span theoretical reflections on key issues through to case-study examples of how PhDs are being deployed and re-thought to address global issues.
