Book excerpt: This book explores the possible relations between Western types of rationality and Buddhism. It also examines some clichés about Buddhism and questions the old antinomies of Western culture ("faith and reason," or "idealism and materialism"). The use of the Buddhist notion of the Two Truths as a hermeneutic device leads to a double or multiple exposure that will call into question our mental habits and force us to ask questions differently, to think "in a new key." Double Exposure is somewhat of an oddity. Written by a specialist for nonspecialists, it is not a book of vulgarization. Although it aims at a better integration of Western and Buddhist thought, it is not an exercise in comparative philosophy or religion. It is neither a contribution to Buddhist scholarship in the narrow sense, nor a contribution to some vague Western "spirituality." Cutting across traditional disciplines and blurring established genres, it provides a leisurely but deeply insightful stroll through philosophical and literary texts, dreams, poetry, and paradoxes.
