Kojin Karatani's Philosophy of Architecture

In this book, Nadir Lahiji introduces Kōjin 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 Kōjin Karatani introduces a different definition of philosophy.
