The history of the development of a soul can be sometimes written by giving a simple bibliography; for a man who lives in a narrow circle and never meets great men personally, seeks to make their acquaintance through books. The fact that the same books do not make the same impression, nor have the same effect upon all, shows their relative powerlessness to convert anybody. For example, we call the criticism with which we agree good; the criticism which contradicts our views is bad. Thus we seem to be educated with preconceived views, and the book which strengthens, expresses and develops these makes an impression on us. The danger of a one-sided education through books is that most books, especially those composed at the end of an era, and at the university, are antiquated. The youth who has received old ideals from his parents and teachers is accordingly necessarily out of date before his education is completed. When he enters manhood, he is generally obliged to fling away his whole stock of old ideas, and be born again, as it were. Time has gone by him, while he was reading the old books, and he finds himself a stranger among his contemporaries
