thought which take account of the reality of change and which realize
its importance in all spheres. A writer on world politics very aptly
reminds us that "life is change, and a League of Peace that aimed at
preserving peace by forbidding change would be a tyranny as oppressive
as any Napoleonic dictatorship. These problems called for periodic
change. The peril of our future is that, while the need for change is
instinctively grasped by some peoples as the fundamental fact of world-
politics, to perceive it costs others a difficult effort of
thought."[Footnote: H. N. Brailsford on Peace and Change, Chap. 3 of his
Book A League of Nations.] However difficult it may be for some
individuals and for some nations to grasp it, the great fact is there--
the reality of change is undeniable.

Bergson himself would give to his philosophy the title, The Philosophy
of Change, and this for a very good reason, for the principle of Change
and an insistence on its reality lies at the root of his
thought.[Footnote: He suggested this as a sub-title to Dr. H. Wildon
Carr for his little work Henri Bergson (People's Books). Dr. Wildon
Carr's later and larger work bears this as its full title.] "We know
that everything changes," we find him saying in his London lectures,
"but it is mere words. From the earliest times recorded in the history
of philosophy, philosophers have never stopped saying that everything
changes; but, when the moment came for the practical application of this
proposition, they acted as if they believed that at the bottom of things
there is immobility and invariability. The greatest difficulties of
philosophy are due to not taking account of the fact that Change and
Movement are universal. It is not enough to say that everything changes
and moves--we must believe it."[Footnote: Second of the four lectures on
La Nature de l'Ame delivered at London University, Oct. 21, 1911. From
report in The Times for Oct. 23, 1911, p. 4.] In order to think Change
