But if the same man be called to consider the merit of a production yet unpublished, he brings an imagination heated with objections to passages which he has yet never heard; he invokes all the powers of criticism, and stores his memory with Taste and Grace, Purity and Delicacy, Manners and Unities, sounds which, having been once uttered by those that understood them, have been since reechoed without meaning, and kept up to the disturbance of the world, by a constant repercussion from one coxcomb to another. He considers himself as obliged to shew, by some proof of his abilities, that he is not consulted to no purpose, and therefore watches every opening for objection, and looks round for every opportunity to propose some specious alteration. Such opportunities a very small degree of sagacity will enable him to find; for, in every work of imagination, the disposition of parts, the insertion of incidents, and use of decorations, may be varied a thousand ways with equal propríety; and as in things nearly equal, that will always seem best to every man which he himself produces; the critick, whose business is only to propose, without the care of execution, can never want the satisfaction of believing that he has suggested very important improvements, nor the power of enforcing his advice by arguments, which, as they appear convincing to himself, either his kindness or his vanity will press obstinately and importunately, without suspicion that he may possibly judge too hastily in favour of his own advice, or inquiry whether the advantage of the new scheme be proportionate to the labour.
It is observed by the younger Pliny, that an orator ought not so much to select the strongest arguments which his cause admits, as to employ all which his imagination can afford: for, in pleading, those reasons are of most value, which will most affect the judges; and the judges, says he, will be always most touched with that which they had before conceived. Every man who is called to give his opinion of a performance, decides upon the same principle; he first suffers himself to form expectations, and then is angry at his disappointment. He lets his imagination rove at large, and wonders that another, equally unconfined in the boundless ocean of possibility, takes a different course.
