ABSTRACT
The enormous new development of the affective faculties, the new ideas dependent on those, the new desires and organic cravings rising into a different and far higher region of imaginative and aesthetic life, all show that a fresh chapter in brain and mind life has been opened. With this new normal development of a higher life comes a special liability to previous kinds of abnormality in brain and mind, abnormality that may extend in character from a slight eccentricity up to an acute attack of mental derangement. There is, of course, no absolutely fixed line or short period marking the two eras of school life and adolescence. During adolescence in the woman the developmental process is more important than in the man, for she then has to acquire the strength and other qualifications to reproduce the race. In the educated classes the higher sort of education only begins at adolescence, and goes on during the greater part of its duration.
