This book is a very important branch of Indian logic, which covers up within its scope the examination of the objects through the means of valid knowledge (pramana) like perception (pratyaksa), inference (anumana) including syllogism. It is traceable in the teachings of Lord Buddha, in the old Buddhist literature like tripitakas, kathavatthu etc. and also in the important works of idealistic thought of Yogacara Buddhism. Dignaga is regarded as the founder of Buddhist logic, who provided a solid footing to it.
Tyhe present work entitled as Concepts of Buddhist Logic is an endeavour to expose all the important points of discussion regarding Buddhist logic e.g. nature of pramana, its kind (perception and interference), theory of validity of cognition, etc. Three types of fallacies (pakshabhasa, hetvabhasa and dristantabhasa) have also dealt with in detail. A chapter on prasanganuman is a special feature of this work. The book has been written in a very simple, lucid but scientific manner. It is anticipated that it will prove to be of great importance to the researchers and scholars of Buddhist logic.
