I have sometimes heard of an Iliad in a nut-shell, but it has been my fortune to have much oftener seen a nut-shell in an Iliad. There is no doubt that human life has received most wonderful advantages from both; but to which of the two the world is chiefly indebted, I shall leave among the curious as a problem worthy of their utmost inquiry. For the invention of the latter, I think the commonwealth of learning is chiefly obliged to the great modern improvement of digressions. The late refinements in knowledge, running parallel to those of diet in our nation, which among men of a judicious taste are dressed up in various compounds, consisting in soups and olios, fricassees and ragouts.

It is true there is a sort of morose, detracting, ill-bred people who pretend utterly to disrelish these polite innovations. And as to the similitude from diet, they allow the parallel, but are so bold as to pronounce the example itself a corruption and degeneracy of taste. They tell us that the fashion of jumbling fifty things together in a dish was at first introduced in compliance to a depraved and debauched appetite, as well as to a crazy constitution, and to see a man hunting through an olio after the head and brains of a goose, a widgeon, or a woodcock, is a sign he wants a stomach and digestion for more substantial victuals. Further, they affirm that digressions in a book are like foreign troops in a state, which argue the nation to want a heart and hands of its own, and often either subdue the natives, or drive them into the most unfruitful corners.

But after all that can be objected by these supercilious censors, it is manifest the society of writers would quickly be reduced to a very inconsiderable number if men were put upon making books with the fatal confinement of delivering nothing beyond what is to the purpose. It is acknowledged that were the case the same among us as with the Greeks and Romans, when learning was in its cradle, to be reared and fed and clothed by invention, it would be an easy task to fill up volumes upon particular occasions without further expatiating from the subject than by moderate excursions, helping to advance or clear the main design. But with knowledge it has fared as with a numerous army encamped in a fruitful country, which for a few days maintains itself by the product of the soil it is on, till provisions being spent, they send to forage many a mile among friends or enemies, it matters not. Meanwhile the neighbouring fields, trampled and beaten down, become barren and dry, affording no sustenance but clouds of dust.

The whole course of things being thus entirely changed between us and the ancients, and the moderns wisely sensible of it, we of this age have discovered a shorter and more prudent method to become scholars and wits, without the fatigue of reading or of thinking. The most accomplished way of using books at present is twofold: either first to serve them as some men do lords, learn their titles exactly, and then brag of their acquaintance; or, secondly, which is indeed the choicer, the profounder, and politer method, to get a thorough insight into the index by which the whole book is governed and turned, like fishes by the tail. For to enter the palace of learning at the great gate requires an expense of time and forms, therefore men of much haste and little ceremony are content to get in by the back-door. For the arts are all in a flying march, and therefore more easily subdued by attacking them in the rear. Thus physicians discover the state of the whole body by consulting only what comes from behind. Thus men catch knowledge by throwing their wit on the posteriors of a book, as boys do sparrows with flinging salt upon their tails. Thus human life is best understood by the wise man’s rule of regarding the end. Thus are the sciences found, like Hercules’ oxen, by tracing them backwards. Thus are old sciences unravelled like old stockings, by beginning at the foot.

Besides all this, the army of the sciences hath been of late with a world of martial discipline drawn into its close order, so that a view or a muster may be taken of it with abundance of expedition. For this great blessing we are wholly indebted to systems and abstracts, in which the modern fathers of learning, like prudent usurers, spent their sweat for the ease of us their children. For labour is the seed of idleness, and it is the peculiar happiness of our noble age to gather the fruit.

Now the method of growing wise, learned, and sublime having become so regular an affair, and so established in all its forms, the number of writers must needs have increased accordingly, and to a pitch that has made it of absolute necessity for them to interfere continually with each other. Besides, it is reckoned that there is not at this present a sufficient quantity of new matter left in Nature to furnish an............
