ed." If the universe be pregnant with purpose, as we all wish
to believe, why should not this purpose work itself out by an
evolution process under law?--and if under law, why not the law of
Probabilities? We who have our lives insured provide for our children
through our knowledge and use of this law; and our plans for their
welfare, in most of the affairs of life, are based upon the
recognition of it. Who will deny to the Great Purpose a similar
resource in producing the universe and in providing for us all?

I add in a concluding section on Literature some references to various
books in English, classified under the headings of the chapters of the
text. These works will further enlighten the reader, and, if he
persevere, possibly make a psychologist of him.

THE STORY OF THE MIND

CHAPTER I.

THE SCIENCE OF THE MIND--PSYCHOLOGY,

Psychology is the science of the mind. It aims to find out all about
the mind--the whole story--just as the other sciences aim to find out
all about the subjects of which they treat--astronomy, of the stars;
geology, of the earth; physiology, of the body. And when we wish to
trace out the story of the mind, as psychology has done it, we find
that there are certain general truths with which we should first
acquaint ourselves; truths which the science has been
