cance of its relation to philosophy.

I have in Part II undertaken to furnish the reader with a map of the
country to which he has been led. To this end I have attempted a brief
survey of the entire programme of philosophy. An accurate and full
account of philosophical terms can be found in such books as Kuelpe's
"Introduction to Philosophy" and Baldwin's "Dictionary of Philosophy,"
and an attempt to emulate their thoroughness would be superfluous, even
if it were conformable to the general spirit of this book. The scope of
Part II is due in part to a desire for brevity, but chiefly to the hope
of furnishing an epitome that shall follow the course of the _natural
and historical differentiation_ of the general philosophical problem.

Finally, I have in Part III sought to present the tradition of
philosophy in the form of general types. My purpose in undertaking so
difficult a task is to acquaint the reader with philosophy in the
concrete; to show how certain underlying principles may determine the
whole circle of philosophical ideas, and give them unity and distinctive
flavor. Part II offers a general classification of philosophical
problems and conceptions independently of any special point of view. But
I have in Part III sought to emphasize the point of view, or the
internal consistency that makes a _system of philosophy_ out of certain
answers to the special problems of philosophy. In such a division into
types, lines are of necessity drawn too sharply. There will be many
historical philosophies that refuse to fit, and many possibilities
unprovided for. I must leave it to the individual reader to overcome
this abstractness through his own reflection upon the intermediate and
variant stand-points.

Although the order is on the whole that of progressive complexity, I
have sought to treat each chapter with independence enough to make it
possible for it to be read separately; and I have provided a carefully
selected bibliography in the hope that this book may serve as a stimulus
and guide to the reading of other books.

The earlier chapters have already appeared as articles: Chapter I in the
_International Journal of Ethics_, Vol. XIII, No. 4; Chapter II in the
_Philosophical Review_, Vol. XI, No. 6; Chapter III in the _Monist_,
Vol. XIV, No. 5; Chapter IV in the _International Journal of Ethics_,
Vol. XV, No. 1; and some paragraphs of Chapter V in the _Journal of
Philosophy, Psychology, and Scientific Methods_, Vol. I
