In this quarrel whole rivulets of ink have been exhausted, and the virulence of both parties enormously augmented. Now, it must be here understood, that ink is the great missive weapon in all battles of the learned, which, conveyed through a sort of engine called a quill, infinite numbers of these are darted at the enemy by the valiant on each side, with equal skill and violence, as if it were an engagement of porcupines. This malignant liquor was compounded, by the engineer who invented it, of two ingredients, which are, gall and copperas; by its bitterness and venom to suit, in some degree, as well as to foment, the genius of the combatants. And as the Grecians, after an engagement, when they could not agree about the victory, were wont to set up trophies on both sides, the beaten party being content to be at the same expense, to keep itself in countenance (a laudable and ancient custom, happily revived of late in the art of war), so the learned, after a sharp and bloody dispute, do, on both sides, hang out their trophies too, whichever comes by the worst. These trophies have largely inscribed on them the merits of the cause; a full impartial account of such a Battle, and how the victory fell clearly to the party that set them up. They are known to the world under several names; as disputes, arguments, rejoinders, brief considerations, answers, replies, remarks, reflections, objections, confutations. For a very few days they are fixed up all in public places, either by themselves or their representatives, for passengers to gaze at; whence the chiefest and largest are removed to certain magazines they call libraries, there to remain in a quarter purposely assigned them, and thenceforth begin to be called books of controversy.

In these books is wonderfully instilled and preserved the spirit of each warrior while he is alive; and after his death his soul transmigrates thither to inform them. This, at least, is the more common opinion; but I believe it is with libraries as with other cemeteries, where some philosophers affirm that a certain spirit, which they call brutum hominis, hovers over the monument, till the body is corrupted and turns to dust or to worms, but then vanishes or dissolves; so, we may say, a restless spirit haunts over every book, till dust or worms have seized upon it—which to some may happen in a few days, but to others later—and therefore, books of controversy being, of all others, haunted by the most disorderly spirits, have always been confined in a separate lodge from the rest, and for fear of a mutual violence against each other, it was thought prudent by our ancestors to bind them to the peace with strong iron chains. Of which invention the original occasion was this: When the works of Scotus first came out, they were carried to a certain library, and had lodgings appointed them; but this author was no sooner settled than he went to visit his master Aristotle, and there both concerted together to seize Plato by main force, and turn him out from his ancient station among the divines, where he had peaceably dwelt near eight hundred years. The attempt succeeded, and the two usurpers have reigned ever since in his stead; but, to maintain quiet for the future, it was decreed that all polemics of the larger size should be hold fast with a chain.
