and what in the most general way we are to think and do, if the
present generation is to make the most of its opportunities as a

The bibliography shows the main sources of the facts and the theories
that have been drawn upon in writing the book. Some of the chapters
have been read in a little different form as lectures before President
G. Stanley Hall's seminar at Clark University. More or less of
repetition, made necessary in order to make these papers, which were
read at considerable intervals, independent of one another, has been
allowed to remain. Perhaps in the printed form this reiteration will
help to emphasize the general psychological basis of the study.
