. These are discussed as
normal though complex activities developed, through the
process of reflection, in the fulfillment of man's inborn
impulses and needs. Thus descriptively to treat these spiritual
enterprises implies on the part of the author a naturalistic
viewpoint whose main outlines have been fixed for this generation
by James, Santayana, and Dewey. To the last-named
the writer wishes to express the very special obligation
that a pupil owes to a great teacher.

The book as a whole, so far as can be judged from the experience
the author and others have had in using it during
the past year as a text at Columbia, should fit well into any
general course in social psychology. It has been increasingly
realized that the student's understanding of contemporary
problems of government and industry is immensely clarified
by a knowledge of the human factors which they involve.
This volume supplies a brief account of the essential facts of
human behavior with especial emphasis on their social
consequences. Part I may be independently used, as it has been
with success, in a general course in social psychology. Part II,
the "Career of Reason," presents material which many
instructors find it highly desirable to use in introductory
philosophy courses, but for which no elementary texts are
available. The usual textbooks deal with the more metaphysical
problems to the exclusion of religion, art, morals, and science,
humanly the most interesting and significant of philosophical
problems. Where, as in many colleges, the introductory
philosophy course is preceded by a course in psychology, the
arrangement of the volume should prove particularly well
suited.

The illustrative material has been drawn, possibly to an
unusual extent, from literature. The latter seems to give the
student in the vivid reality of specific situations facts which
the psychologist is condemned, from the necessities of scientific
method, to discuss in the abstract.

The book follows more or less closely that part of the syllabus
for the course in Contemporary Civilization, which is
called "The World of Human Nature," which section of the
outline was chiefly the joint product of collaboration by
Professor John J. Coss and the author. To the former the author
wishes to express his large indebtedness. Also to Miss Edith
G. Taber, for her careful and valuable editing of the manuscript
in preparation for the printer, he desires to convey his
deep appreci
