Mr. Salt, education plus vegetarianism; Fagin, education plus crime. The truth is, that there is nothing in common at all between these teachers, except that they teach. In short, the only thing they share is the one thing they profess to dislike; the general idea of authority. It is quaint that people talk of separating dogma from education. Dogma is actually the only thing that cannot be separated from education. It is education. A teacher who is not dogmatic is simply a teacher who is not teaching.
