This book contains lectures on the Crituque of Pure Reason delivered by J.N. Mohanty at Temple University, USA. These lectures are a culmination of Mohanty's life-long engagemen with the Philosophy of Kant. With a view to situating Kany in the proper perspective the author carefully mentions and explains some points of contact and those of contrast between Kant and some pre-Kantian philosophers on the one hand, and between Kant and many post-Kantian philosophers on the other.
