PREFACE
xix
acknowledge my indebtedness to Sir B. N. Seal, who was a versatile genius and an eminent authority in Indian and Western philosophy, and from whom I received great inspiration and valuable guidance in the early days of my researches in Indian philosophy. I have to express further my deep sense of gratitude to Professor K. C. Bhattacharyya, a profound thinker and astute metaphysician, who for some time held the George V Chair of Philosophy in the Calcutta University. It was my proud privilege to sit at his feet, and discuss and clear up some of the abstruse problems of logic and philosophy treated in this book. I have to acknowledge with thanks tho great help I have received from MM. Pandit Sītārām Sāstrı, of the Calcutta University, while studying some original works of the Nyāya philosophy.
I have to express further my most grateful thanks to the great savant, Sır S Radhakrishnan, George V Professor of Philosophy, Calcutta University, and Spalding Professor of Eastern Religions and Ethics, Oxford University, for the constant encouragement, help and guidance I have received from bim in completing this work. My thanks are also due to my esteemed friend and talented writer, Dr. D. M. Datta of the Patna College, for reading considerable parts of the manuscript and for making valuable suggestions. I am obliged to the authorities of the Calcutta University, especially to Dr. Syamaprasad Mookerjee, its ex-ViceChancellor, and Mr. Jogeschandra Chakravorti, its Registrar, for kindly undertaking the publication of the book at the University Press. I must thank also Mr. Dinabandhu Ganguli, Superintendent, Mr. Bhupendralal Banerjee, Printer, and Mr. Jatındramohan Roy, Reader of the Press, for their help and co-operation in the printing of this work.
