The task of an author is, either to teach what is not known, or to recommend known truths by his manner of adorning them; either to let new light in upon the mind, and open new scenes to the prospect, or to vary the dress and situation of common objects, so as to give them fresh grace and more powerful attractions, to spread such flowers over the regions through which the intellect has already made its progress, as may tempt it to return, and take a second view of things hastily passed over, or negligently regarded. Either of these labours is very difficult, because, that they may not be fruitless, men must not only be persuaded of their errours, but reconciled to their guide; they must not only confess their ignorance, but, what is still less pleasing, must allow that he from whom they are to learn is more knowing than themselves. It might be imagined that such an employment was in itself sufficiently irksome and hazardous; that none would be found so malevolent as wantonly to add weight to the stone of Sisyphus; and that few endeavours would be used to obstruct those advances to reputation, which must be made at such an expense of time and thought, with so great hazard in the miscarriage, and with so little advantage from the success. Yet there is a certain race of men, that either imagine it their duty, or make it their amusement, to hinder the reception of every work of learning or genius, who stand as sentinels in the avenues of fame, and value themselves upon giving Ignorance and Envy the first notice of a prey. To these men, who distinguish themselves by the appellation of Criticks, it is necessary for a new author to find some means of recommendation. It is probable, that the most malignant of these persecutors might be somewhat softened, and prevailed on, for a short time, to remit their fury. Having for this purpose considered many expedients, I find in the records of ancient times, that Argus was lulled by musick, and Cerberus quieted with a sop; and am, therefore, inclined to believe that modern criticks, who, if they have not the eyes, have the watchfulness of Argus, and can bark as loud as Cerberus, though, perhaps, they cannot bite with equal force, might be subdued by methods of the same kind. I have heard how some have been pacified with claret and a supper, and others laid asleep by the soft notes of flattery. Though the nature of my undertaking gives me sufficient reason to dread the united attacks of this virulent generation, yet I have not hitherto persuaded myself to take any measures for flight or treaty. For I am in doubt whether they can act against me by lawful authority, and suspect that they have presumed upon a forged commission, styled themselves the ministers of Criticism, without any authentick evidence of delegation, and uttered their own determinations as the decrees of a higher judicature.
