ase, physics
does not assume the existence of matter.

The view that seems to me to reconcile the materialistic tendency of
psychology with the anti-materialistic tendency of physics is the view
of William James and the American new realists, according to which the
"stuff" of the world is neither mental nor material, but a "neutral
stuff," out of which both are constructed. I have endeavoured in this
work to develop this view in some detail as regards the phenomena with
which psychology is concerned.

My thanks are due to Professor John B. Watson and to Dr. T. P. Nunn
for reading my MSS. at an early stage and helping me with many valuable
suggestions; also to Mr. A. Wohlgemuth for much very useful information
as regards important literature. I have also to acknowledge the help
of the editor of this Library of Philosophy, Professor Muirhead, for
several suggestions by which I have profited.

The work has been given in the form of lectures both in London and
Peking, and one lecture, that on Desire, has been published in the
Athenaeum.

There are a few allusions to China in this book, all of which were
written before I had been in China, and are not intended to be taken by
the reader as geographically accurate. I have used "China" merely as
a synonym for "a distant country," when I wanted illustrations of
unfamiliar things.

THE ANALYSIS OF MIND

LECTURE I. RECENT CRITICISMS OF "CONSCIOUSNESS"

There are certain occurrences which we are in the habit of calling
"mental." Among these we may take as typical BELIEVING and DESIRING.
The exact definition of the word "mental" will, I hope, emerge as
the lectures proceed; for the present, I shall mean by it whatever
occurrences would commonly be called mental.

I wish in these lectures to analyse as fully as I can what it is that
really takes place when we, e.g. believe or desire. In this first
lecture I shall be concern
