I have sometimes heard of an Iliad in a nutshell; but it hath been my fortune to have much oftener seen a nutshell in an Iliad. There is no doubt that human life hath 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.
'Tis 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 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. Farther, 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, 'tis 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. 'Tis 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 farther expatiating from the subjects, than by moderate excursions, helping to advance or clear the main design. But with knowledge it hath 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 two-fold; 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 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's 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 hath 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 and adorn any one particular subject, to the extent of a volume. This I am told by a very skilful computer, who hath given a full demonstration of it from rules of arithmetic.
This will stand as an incontestable argument, that our modern wits are not to reckon upon the infinity of matter for a constant supply. What remains therefore, but that our last recourse must be had to large indexes, and little compendiums? quotations must be plentifully gathered, and booked in alphabet; to this end, though authors need be little consulted, yet critics, and commentators, and lexicons, carefully must. But above all, those judicious collectors of bright parts, and flowers, and observandas, are to be nicely dwelt on, by some called the sieves and boulters of learning; though it is left undetermined, whether they dealt in pearls or meal; and consequently, whether we are more to value that which passed through, or what staid behind.
By these methods, in a few weeks, there starts up many a writer, capable of managing the profoundest and most universal subjects. For, what though his head be empty, provided his common-place book be full; and if you will bate him but the circumstances of method, and style, and grammar, and invention; allow him but the common privileges of transcribing from others, and digressing from himself, as often as he shall see occasion; he will desire no more ingredients towards fitting up a treatise, that shall make a very comely figure on a bookseller's shelf; there to be preserved neat and clean for a long eternity, adorned with the heraldry of its title fairly inscribed on a label; never to be thumbed or greased by students, nor bound to everlasting chains of darkness in a library: but, when the fulness of time is come, shall happily undergo the trial of purgatory, in order to ascend the sky.
Without these allowances, how is it possible we modern wits should ever have an opportunity to introduce our collections, listed under so many thousand heads of a different nature; for want of which, the learned world would be deprived of infinite delight, as well as instruction, and we ourselves buried beyond redress, in an inglorious and undistinguished oblivion?
From such elements as these, I am alive to behold the day, wherein the corporation of authors can outvie all its brethren in the field. A happiness derived to us, with a great many others, from our Scythian ancestors; among whom the number of pens was so infinite, that the Grecian eloquence [Herodot. lib. 4.] had no other way of expressing it, than by saying, that in the regions, far to the north, it was hardly possible for a man to travel, the very air was so replete with feathers.
The necessity of this digression will easily excuse the length; and I have chosen for it as proper a place as I could readily find. If the judicious reader can assign a fitter, I do here empower him to remove it into any other corner he pleases. And so I return, with great alacrity, to pursue a more important concern.
