Since she is about to betroth to him the handmaiden of wisdom, encyclical instruction, he says that she did not forget the duty which she owed to her mistress, but knew that she was, both in law and in her master’s feelings, his wife, and that she herself was only such because of necessity and the force of opportunity. And this happens to every man who is fond of learning. And he who has experienced it may be looked upon as the most trustworthy witness to this fact.
