Men of study and imagination are frequently upbraided by the industrious and plodding sons of care, with passing too great a part of their life in a state of inaction.  But these defiers of sleep seem not to remember that though it must be granted them that they are crawling about before the break of day, it can seldom be said that they are perfectly awake; they exhaust no spirits, and require no repairs; but lie torpid as a toad in marble, or at least are known to live only by an inert and sluggish locomotive faculty, and may be said, like a wounded snake, to “drag their slow length along.”

Man has been long known among philosophers by the appellation of the microcosm, or epitome of the world:  the resemblance between the great and little world might, by a rational observer, be detailed to many particulars; and to many more by a fanciful speculatist.  I know not in which of these two classes I shall be ranged for observing, that as the total quantity of light and darkness allotted in the course of the year to every region of the earth is the same, though distributed at various times and in different portions; so, perhaps, to each individual of the human species, nature has ordained the same quantity of wakefulness and sleep; though divided by some into a total quiescence and vigorous exertion of their faculties, and, blended by others in a kind of twilight of existence, in a state between dreaming and reasoning, in which they either think without action, or act without thought.

The poets are generally well affected to sleep:  as men who think with vigour, they require respite from thought; and gladly resign themselves to that gentle power, who not only bestows rest, but frequently leads them to happier regions, where patrons are always kind, and audiences are always candid; where they are feasted in the bowers of imagination, and crowned with flowers divested of their prickles, and laurels of unfading verdure.

The more refined and penetrating part of mankind, who take wide surveys of the wilds of life, who see the innumerable terrours and distresses that are perpetually preying on the heart of man, and discern with unhappy perspicuity, calamities yet latent in their causes, are glad to close their eyes upon the gloomy prospect, and lose in a short insensibility the remembrance of others’ miseries and their own.  The hero has no higher hope, than that, after having routed legions after legions, and added kingdom to kingdom, he shall retire to milder happiness, and close his days in social festivity.  The wit or the sage can expect no greater happiness, than that, after having harassed his reason in deep researches, and fatigued his fancy in boundless excursions, he shall sink at night in the tranquillity of sleep.
