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 and adorn any one particular subject to the extent of a volume. This I am told by a very skilful computer, who has given a full demonstration of it from rules of arithmetic. 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 bolters 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 commonplace-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 guild. 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 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 impower him to remove it into any other corner he pleases.

A

DIGRESSION CONCERNING

THE

ORIGINAL, THE USE, AND IMPROVE-
MENT OF MADNESS IN A COMMON-
WEALTH

NOR shall it any ways detract from the just reputation of this famous sect [of the Aeolists], that its rise and institution are owing to such an author as I have described Jack to be; a person whose intellectuals were overturned, and his brain shaken out of its natural position; which we commonly suppose to be a distemper, and call by the name of madness or phrensy. For, if we take a survey of the greatest actions that have been performed in the world under the influence of single men; which are, the establishment of new empires by conquest; the advance and progress of new schemes in philosophy; and the contriving, as well as the propagating, of new religions; we shall find the authors of them all to have been persons whose natural reason had admitted great revolutions, from their diet, their education, the prevalency of some certain temper, together with the particular influence of air and climate. Besides, there is something individual in human minds, that easily kindles at the accidental approach and collision of certain circumstances, which, though of paltry and mean appearance, do often flame out into the greatest

emergencies of life. For great turns are not always given by strong hands, but by lucky adaption, and at proper seasons; and it is of no import where the fire was kindled, if the vapour has once got up into the brain. For the upper region of man is furnished like the middle region of the air: the materials are formed from causes of the widest difference, yet produce at last the same substance and effect. Mists arise from the earth, steams from dunghills, exhalations from the sea, and smoke from fire; yet all clouds are the same in composition as well as consequences. Thus far, I suppose, will easily be granted me: and then it will follow that, as the face of nature never produces rain but when it is overcast and disturbed, so human understanding, seated in the brain, must be troubled and overspread by vapours ascending from the lower faculties to water the invention and render it fruitful.

Let us next examine the great introducers of new schemes in philosophy, and search till we can find from what faculty of the soul the disposition arises in mortal man of taking it into his head to advance new systems, with such an eager zeal, in things agreed on all hands impossible to be known: from what seeds this disposition springs, and to what quality of human nature these grand innovators have been indebted for their number of disciples. Because it is plain that several of the chief among them, both ancient and modern, were usually mistaken by their adversaries, and indeed by all except their own followers, to have been persons crazed, or out of their wits; having generally proceeded, in the common course of their words and actions, by a method very different from the vulgar dictates of unrefined reason; agreeing for

the most part in their several models with their present undoubted successors in the academy of modern Bedlam; whose merits and principles I shall farther examine in due place. Of this kind were Epicurus, Diogenes, Apollonius, Lucretius, Paracelsus, Descartes, and others; who, if they were now in the world, tied fast, and separate from their followers, would, in this our undistinguishing age, incur manifest danger of phlebotomy, and whips, and chains, and dark chambers, and straw. For what man, in the natural state or course of thinking, did ever conceive it in his power to reduce the notions of all mankind exactly to the same length, and breadth, and height of his own? yet this is the first humble and civil design of all innovators in the empire of reason. Epicurus modestly hoped that, one time or other, a certain fortuitous concourse of all men's opinions, after perpetual justlings, the sharp with the smooth, the light and the heavy, the round and the square, would by certain clinamina unite in the notions of atoms and void, as these did in the originals of all things. Cartesius reckoned to see, before he died, the sentiments of all philosophers, like so many lesser stars in his romantic system, wrapped and drawn within his own vortex. Now, I would gladly be informed how it is possible to account for such imaginations as these in particular men, without recourse to my phenomenon of vapours ascending from the lower faculties to overshadow the brain, and there distilling into conceptions for which the narrowness of our mother-tongue has not yet assigned any other name besides that of madness or phrensy. Let us therefore now conjecture how it comes to pass that none of these great prescribers do ever fail providing themselves and
