Buddhism is essentially a teaching about liberation - from suffering, ignorance, selfishness and continued rebirth. Knowledge of the way things really are is thought by many Buddhists to be vital in bringing about this emancipation. This book is a philosophical study of the notion of liberating knowledge as it occurs in a range of Buddhist sources. The book assesses the common Buddhist idea that knowledge of the three characteristics of existence (impermanence, not-self and suffering) is the key to liberation. It argues that this claim must be seen in the context of the Buddhist path and training as a whole. Detailed attention is also given to anti-realist, sceptical and mystical strands within the Buddhist tradition, all of which make distinctive claims about liberating knowledge and the nature of reality. David Burton seeks to uncover various problematic assumptions which underpin the Buddhist worldview. Sensitive to the wide diversity of philosophical perspectives and interpretation that Buddhism has engendered, this book makes a serious contribution to critical and philosophically aware engagement with Buddhist thought. Written in an accessible style, it should be of value to all those interested in Buddhist studies and broader issues in comparative philosophy and religion.
