Ver. 201. _Of all the causes, &c._] Having, in the first part, delivered rules for perfecting the art of criticism, the second is employed in explaining the impediments to it. The order of the two parts was well adjusted. For the causes of wrong judgment being pride, superficial learning, a bounded capacity, and partiality, they to whom this part is principally addressed, would not readily be brought either to see the malignity of the causes, or to own themselves concerned in the effects, had not the author previously both enlightened and convinced them, by the foregoing observations, on the vastness of art, and narrowness of wit; the extensive study of human nature and antiquity; and the characters of ancient poetry and criticism; the natural remedies to the four epidemic disorders he is now endeavouring to redress. Ver. 201. _Of all the causes, &c._] The first cause of wrong judgment is pride. He judiciously begins with this, from ver. 200 to 215, as on other accounts, so on this, that it is the very thing which gives modern criticism its character, whose complexion is abuse and censure. He calls it the vice of fools, by which term is not meant those to whom nature has given no judgment (for he is here speaking of what misleads the judgment), but those to whom learning and study have given more erudition than taste, as appears from the happy similitude of an ill-nourished body, where the same words which express the cause, express likewise the nature of pride: For as in bodies, thus in souls, we find, What wants in blood and spirits, swelled with wind. It is the business of reason, he tells us, to dispel the cloud in which pride involves the mind: but the mischief is, that the rays of reason, diverted by self-love, sometime gild this cloud, instead of dispelling it. So that the judgment, by false lights reflected back upon itself, is still apt to be a little dazzled, and to mistake its object. He therefore advises to call in still more helps: Trust not yourself; but your defects to know, Make use of ev'ry friend and ev'ry foe. Both the beginning and conclusion of this precept are remarkable. The question is of the means to subdue pride. He directs the critic to begin with a distrust of himself; and this is modesty, the first mortification of pride: and then to seek the assistance of others, and make use even of an enemy; and this is humility, the last mortification of pride: for when a man can once bring himself to submit to profit by an enemy, he has either already subdued his vanity, or is in a fair way of so doing. Ver. 215. _A little learning, &c._] We must here remark the poet's skill in his disposition of the causes obstructing true judgment. Each general cause which is laid down first, has its own particular cause in that which follows. Thus, the second cause of wrong judgment, superficial learning, is what occasions that critical pride, which he places first.
