The more a man has learnt, the easier it is for him to learn still more - always assuming that he has not been taught in a spirit of dogmatism. Ignorant people have never been compelled to change their mental habits, and have stiffened into an unchangeable attitude. It is not only that they are credulous where they should be sceptical; it is just as much that they are incredulous where they should be receptive
