In this book, Nadir Lahiji introduces Kojin Karatani?s theoretical-philosophical project and demonstrates its affinity with Kant?s critical philosophy founded on ?architectonic reason?. From the ancient Greeks we have inherited a definition of the word ?philosophy? as Sophia?wisdom. But in his book Architecture as Metaphor Kojin Karatani introduces a different definition of philosophy. Here, Karatani critically defines philosophy not in association with Sophia but in relation to foundation as the Will to Architecture. In this novel definition resides the notion that in Western thought a crisis persistently reveals itself with every attempt to build a system of knowledge on solid ground. This book reveals the implications of this extraordinary exposition. This is the first book to uncover Kojin Karatani?s highly significant ideas on architecture for both philosophical and architectural audiences.
