The primary danger of this system of education—very properly qualified as Latin—consists in the fact that it is based on the fundamental psychological error that the intelligence is developed by the learning by heart of text-books. Adopting this view, the endeavour has been made to enforce a knowledge of as many hand-books as possible. From the primary school till he leaves the university a young man does nothing but acquire books by heart without his judgment or personal initiative being ever called into play. Education consists for him in reciting by heart and obeying.
