I am much indebted to my esteemed friends Dr E.J. Thomas of the Cambridge University Library and Mr Douglas Ainslie for their kindly revising the proofs of this work, in the course of which they improved my English in many places. To the former I am also indebted for his attention to the transliteration of a large number of Sanskrit words, and also for the whole-hearted sympathy and great friendliness with which he assisted me with his advice on many points of detail, in particular the exposition of the Buddhist doctrine of the cause of rebirth owes something of its treatment to repeated discussions with him.
I also wish to express my gratefulness to my friend Mr N.K. Siddhanta, M.A., late of the Scottish Churches College, and Mademoiselle Paule Povie for the kind assistance they have rendered in preparing the index. My obligations are also due to the Syndics of the Cambridge University Press for the honour they have done me in publishing this work.
To scholars of Indian philosophy who may do me the honour of reading my book and who may be impressed with its inevitable

shortcomings and defects, I can only pray in the words of Hemacandra:
Pramâ@nasiddhântaviruddham atra
Yatkiñciduktam matimândyado@sât
Mâtsaryyam utsâryya tadâryyacittâ@h
Prasâdam âdhâya vis'odhayantu. [Footnote ref 1]
