This book presents a collection of essays, setting out both the special concern of classical Indian thought and some of its potential contributions to global philosophy. It presents some key arguments made by different schools about this special concern: the way in which attainment of knowledge of reality transforms human nature in a fundamentally liberating way. It then goes on to look in detail at two areas in contemporary global philosophy – the ethics of difference, and the metaphysics of consciousness – where this classical Indian commitment to the spiritually transformative power of knowledge can lead to critical insights, even for those who do not share its presuppositions. Close reading of technical Indian texts is combined with wide-ranging and often comparative analysis of philosophical issues, to derive original arguments from the Indian material through an analytic method that is seldom mastered by philosophers of non-western traditions.
