The learned editor of this new four-volume collection from Routledge argues that its subject matter is ‘a vast-and vastly undersurveyed-body of inquiry into the most fundamental problems of philosophy. As the broader discipline of philosophy continues to evolve into a genuinely international field, "Indian Philosophy" stands for an unquantifiably precious part of the human intellectual biosphere. For those who are interested in the way in which culture influences structures of thought, for those who want to study alternative histories of ideas, and for those who are merely curious to know what some of the world’s greatest thinkers have thought about some of the most intractable and central philosophical puzzles, Indian Philosophy is a domain of unparalleled richness and importance. And in its potential for cross-fertilization with ideas from other philosophical cultures-Greek, Chinese, European, African, Arabic, and Anglophone-Indian Philosophy is a resource that any creative philosopher can and should draw upon.’
