The Introduction. I HAVE sent, Nicander, the reflections of some spare hours concerning Hearing, digested into the following short essay, that being out of the hands of governors and come to man’s estate, you may know how to pay a proper attention to those who would advise you. For that libertinism which some wild young fellows, for want of more happy education, mistake for liberty, subjects them to harder tyrants than their late tutors and masters, even to their own vicious inclinations, which, as it were, break loose upon them. And as Herodotus observes of women, that they put off modesty with their shift, so some young men lay aside with the badges of minority all the sense of shame or fear, and divested of the garment of modesty which sat so well upon them are covered with insolence. But you, who have often heard that to follow God and to obey reason are all one, cannot but believe that men of best sense in passing from minority to manhood do not throw off the government, but simply change their governor. In the room of some mercenary pedant, they receive that divine guide and governor of human life, reason, under whose subjection alone men are properly said to live in freedom. For they only live at their own will who have learned to will as they ought; and that freedom of will which appears in unconstrained appetites and unreasonable actions is mean and narrow, and accompanied with much repentance.
