'Bell does an excellent job of charting the German psychology of his chosen period, exploring the expression of psychological theories … He succeeds admirably in one of his stated goals, which is to show that theoretical developments in psychology had a significant impact upon the literature and thought of the period. … As an illumination of an important part of psychology's 'long past', this work is masterful … students of literature and comparative literature will celebrate Bell's exploration of the rich vein of psychological ideas to be found in the German literature and thought of the period covered.'
