These pleasures, I believe, may sometimes be indulged to those, who come to a subject of disquisition with minds full of ideas, and with fancies so vigorous, as easily to excite, select, and arrange them. To write is, indeed, no unpleasing employment, when one sentiment readily produces another, and both ideas and expressions present themselves at the first summons; but such happiness, the greatest genius does not always obtain; and common writers know it only to such a degree, as to credit its possibility. Composition is, for the most part, an effort of slow diligence and steady perseverance, to which the mind is dragged by necessity or resolution, and from which the attention is every moment starting to more delightful amusements. It frequently happens, that a design which, when considered at a distance, gave flattering hopes of facility, mocks us in the execution with unexpected difficulties; the mind which, while it considered it in the gross, imagined itself amply furnished with materials, finds sometimes an unexpected barrenness and vacuity, and wonders whither all those ideas are vanished, which a little before seemed struggling for emission. Sometimes many thoughts present themselves; but so confused and unconnected, that they are not without difficulty reduced to method, or concatenated in a regular and dependent series; the mind falls at once into a labyrinth, of which neither the beginning nor end can be discovered, and toils and struggles without progress or extrication. It is asserted by Horace, that, "if matter be once got together, words will be found with very little difficulty;" a position which, though sufficiently plausible to be inserted in poetical precepts, is by no means strictly and philosophically true. If words were naturally and necessarily consequential to sentiments, it would always follow, that he who has most knowledge must have most eloquence, and that every man would clearly express what he fully understood: yet we find, that to think, and discourse, are often the qualities of different persons: and many books might surely be produced, where just and noble sentiments are degraded and obscured by unsuitable diction. Words, therefore, as well as things, claim the care of an author. Indeed of many authors, and those not useless or contemptible, words are almost the only care: many make it their study, not so much to strike out new sentiments, as to recommend those which are already known to more favourable notice by fairer decorations; but every man, whether he copies or invents, whether he delivers his own thoughts or those of another, has often found himself deficient in the power of expression, big with ideas which he could not utter, obliged to ransack his memory for terms adequate to his conceptions, and at last unable to impress upon his reader the image existing in his own mind.
