Seeing, therefore, that those books, and those in great abundance, which are likeliest to taint both life and doctrine, cannot be suppressed without the fall of learning and of all ability in disputation, and that these books of either sort are most and soonest catching to the learned, from whom to the common people whatever is heretical or dissolute may quickly be conveyed, and that evil manners are as perfectly learnt without books a thousand other ways which cannot be stopped, and evil doctrine not with books can propagate, except a teacher guide, which he might also do without writing, and so beyond prohibiting, I am not able to unfold, how this cautelous enterprise of licensing can be exempted from the number of vain and impossible attempts. And he who were pleasantly disposed could not well avoid to liken it to the exploit of that gallant man who thought to pound up the crows by shutting his park gate.
Besides another inconvenience, if learned men be the first receivers out of books and dispreaders both of vice and error, how shall the licensers themselves be confided in, unless we can confer upon them, or they assume to themselves above all others in the land, the grace of infallibility and uncorruptedness? And again, if it be true that a wise man, like a good refiner, can gather gold out of the drossiest volume, and that a fool will be a fool with the best book, yea or without book; there is no reason that we should deprive a wise man of any advantage to his wisdom, while we seek to restrain from a fool, that which being restrained will be no hindrance to his folly. For if there should be so much exactness always used to keep that from him which is unfit for his reading, we should in the judgment of Aristotle not only, but of Solomon and of our Saviour, not vouchsafe him good precepts, and by consequence not willingly admit him to good books; as being certain that a wise man will make better use of an idle pamphlet, than a fool will do of sacred Scripture.
