hoped that perusal of the following pages will lead to a study of the
writings of the philosopher himself. This is a work whose primary aim is
the clear exposition of Bergson's ideas, and the arrangement of chapters
has been worked out strictly with that end in view. An account of his
life is prefixed. An up-to-date bibliography is given, mainly to meet
the needs of English readers; all the works of Bergson which have
appeared in England or America are given, and the comprehensive list of
articles is confined to English and American publications. The
concluding chapters endeavour to estimate the value of Bergson's thought
in relation to Politics (especially Syndicalism), Ethics, Religion, and
the development of thought generally.

My thanks are due to Professor Mair, Professor of Philosophy in the
University of Liverpool, for having read the MS. while in course of
preparation, for contributing an introduction, for giving some helpful
criticism and suggestions, and, what is more, for stimulus and
encouragement given over several years of student life.

Professor Bergson has himself expressed his approval of the general form
of treatment, and I am indebted to him for information on a number of
points. To Dr. Gillespie, Professor of Philosophy at Leeds, I am
indebted for a discussion of most of the MS. following the reading of
it. My thanks are also due to Miss Margaret Linn, whose energetic and
careful assistance in preparing the MS. for the press was invaluable. I
wish also to acknowledge kindness shown in supplying information on
certain points in connexion with the bibliography by Mr. F. C.
Nicholson, Librarian of the University of Edinburgh, by Mr. R. Rye,
Librarian to the University of London, and by the University of London
Press. I am grateful to Professor Bergson and to the Delegates of the
Oxford University Press for permission to quote from La Perception du
