Human life consists of years, months and days: each day contains twenty-four hours. Of these hours how many belong to the province of intellect? "There is," as Solomon says, "a time for all things." There must be a time for sleep, a time for recreation, a time for exercise, a time for supplying the machine with nourishment, and a time for digestion. When all these demands have been supplied, how many hours will be left for intellectual occupation? These remarks, as I have said, are intended principally to apply to the subject of productive literature. Now, of the hours that remain when all the necessary demands of human life have been supplied, it is but a portion, perhaps a small portion, that can be beneficially, judiciously, employed in productive literature, or literary composition. It is true, that there are many men who will occupy eight, ten, or twelve hours in a day, in the labour of composition. But it may be doubted whether they are wisely so occupied. It is the duty of an author, inasmuch as he is an author, to consider, that he is to employ his pen in putting down that which shall be fit for other men to read. He is not writing a letter of business, a letter of amusement, or a letter of sentiment, to his private friend. He is writing that which shall be perused by as many men as can be prevailed on to become his readers. If he is an author of spirit and ambition, he wishes his productions to be read, not only by the idle, but by the busy, by those who cannot spare time to peruse them but at the expence of some occupations which ought not to be suspended without an adequate occasion. He wishes to be read not only by the frivolous and the lounger, but by the wise, the elegant, and the fair, by those who are qualified to appreciate the merit of a work, who are endowed with a quick sensibility and a discriminating taste, and are able to pass a sound judgment on its beauties and defects. He advances his claim to permanent honours, and desires that his lucubrations should be considered by generations yet unborn. A person, so occupied, and with such aims, must not attempt to pass his crudities upon the public. If I may parody a celebrated aphorism of Quintilian, I would say, "Magna debetur hominibus reverentia(8):" in other words, we should carefully examine what it is that we propose to deliver in a permanent form to the taste and understanding of our species. An author ought only to commit to the press the first fruits of his field, his best and choicest thoughts. He ought not to take up the pen, till he has brought his mind into a fitting tone, and ought to lay it down, the instant his intellect becomes in any degree clouded, and his vital spirits abate of their elasticity. (8) Mankind is to be considered with reverence.
