The Elusive Way to the MiddleKnowing Illusion: Bringing a Tibetan Debate into Contemporary Discourse is the fruit of collaborative efforts by the Yakherds, a group of scholars stemming from the earlier Cowherds, in which two of the present herdsmen—Sonam Thakchöe and Jay Garfield—were active as well.1 In moving from the broad issues of Buddhist philosophy that occupied the Cowherds to a tightly focused study of a particular debate in Tibet, the group has parted from the gentle cattle of the Indian plains to tend more rugged Himalayan stock. The present work, in two volumes, offers an exceptionally lucid guide to some of the main lines of Madhyamaka thought in Tibet and the disputes that these engendered. It constitutes an essential contribution to our knowledge of the philosophical traditions of Tibetan Buddhism, but, beyond this, merits the attention of those focusing on their Indian background and on Buddhist philosophies more generally. Indeed, Knowing Illusion is among the rare works in this area that may be profitably taken up by philosophers who are not specifically concerned with Buddhist or other Asian ways of thought, but who may wish to explore approaches beyond those of the Euro-American tradition to some of the central topics of philosophy overall: truth and falsehood, knowledge and ignorance, existence and illusion, belief and argument. Of the many interesting [End Page 1023] questions raised in Knowing Illusion, whether from the perspective of specialized Tibetan Buddhist Studies or of philosophy more broadly, only a sample can be addressed in the space of this review.The unifying thread in Knowing Illusion is a series of written disputes that were provoked by a fifteenth-century teacher belonging to the Sakyapa order of Tibetan Buddhism, Taktsang Sherab Rinchen (1405–1477), in his treatise titled Freedom from Extremes Accomplished through Comprehensive Knowledge of Philosophy (hereinafter Comprehensive Knowledge of Philosophy).2 Central to these debates was the challenge of squaring the Madhyamaka philosophy of Nāgārjuna (second century c.e.), whose teaching of ultimate emptiness (śūnyatā) seemed to undermine most—perhaps all—claims to knowledge, with the positive theory of knowledge (pramāṇa) advanced by Dignāga (fifth century c.e.) and Dharmakīrti (sixth century c.e.). The problem had already preoccupied Indian Buddhist thinkers, including philosophers Bhāviveka (sixth century c.e.) and Śāntarakṣita (eighth century c.e.), who sought to harmonize the insights of Madhyamaka with those of the pramāṇa school, and Dharmakīrti's contemporary Candrakīrti, whose trenchant interpretations of Nāgārjuna appeared to undermine the entire project of a 'theory of knowledge'.3 In Tibet, thinkers of the former camp came to be known as proponents of Svātantrika-Mādhyamika (so-called because they affirmed that emptiness could be established through positive proof, svatantra), while those allied with Candrakīrti were said to follow Prāsaṅgika-Mādhyamika (who allowed only indirect proof, reductio ad absurdum, or prasaṅga).4The debate reemerged forcefully in Tibet, and not merely as a historical exercise, in tandem with the expansion of monastic colleges there during the twelfth century, as Tibetan teachers increasingly elaborated original perspectives on the Indian classics. Many aspects of the Svātantrika/Prāsaṅgika split were co. (shrink)
