Ver. 29, 30. Go, teach Eternal Wisdom, &c.] These two lines are a conclusion from all that had been said from ver. 18 to this effect: "Go now, vain man, elated with thy acquirements in real science, and imaginary intimacy with God; go, and run into all the extravagances I have exploded in the first Epistle, where thou pretendest to teach Providence how to govern; then drop into the obscurities of thy own nature, and thereby manifest thy ignorance and folly."
Ver. 31. Superior beings, &c.] In these lines the poet speaks to this effect: "But to make you fully sensible of the difficulty of this study, I shall instance in the great Newton himself, whom, when superior beings, not long since, saw capable of unfolding the whole law of nature, they were in doubt whether the owner of such prodigious sagacity should not be reckoned of their order, just as men, when they see the surprising marks of reason in an ape, are almost tempted to rank him with their own kind." And yet this wondrous man could go no further in the knowledge of himself than the generality of his species. M. du Resnel, who understood nothing of all this, translates these four celebrated lines thus:
Des célestes esprits la vive intelligence
Regarde avec pitié notre foible science;
Newton, le grand Newton, que nous admirons tous,
Est peut-être pour eux, ce qu'un singe est pour nous.
But it is not the pity, but the admiration of the celestial spirits which is here spoken of. And it was for no slight cause they admired; it was, to see a mortal man unfold the whole law of nature. By which we see it was not Mr. Pope's intention to bring any of the ape's qualities, but its sagacity, into the comparison. But why the ape's, it may be said, rather than the sagacity of some more decent animal, particularly the half-reasoning elephant, as the poet calls it; which, as well on account of this its excellence, as for its having no ridiculous side, like the ape, on which it could be viewed, seems better to have deserved this honour? I reply, because, as a shape resembling human (which only the ape has) must be joined with great sagacity, to raise a suspicion that the animal, thus endowed, is related to man, so the spirituality, which Newton had in common with angels, joined to a penetration superior to man, made those beings suspect he might be one of their order. On this ground of relation, we see the whole beauty of the thought depends. And here let me take notice of a new species of the sublime, of which our poet may be justly said to be the maker; so new, that we have yet no name for it, though of a nature distinct from every other known beauty of poetry. The two great perfections in works of genius are wit and sublimity. Many writers have been witty; some have been sublime; and a few have even possessed both these qualities separately. But none, that I know of, besides our poet, hath had the art to incorporate them; of which he hath given many examples, both in this Essay, and his other poems; one of the noblest being the passage in question. This seems to be the last effort of the imagination to poetical perfection; and in this compounded excellence, the wit receives a dignity from the sublime, and the sublime a splendour from the wit, which, in their state of separate existence, they neither of them had. Yet a late critic, who writes with the decision of a Lord of Session on Parnassus, thinks otherwise: "It may be gathered," says he, "from what is said above, that wit and ridicule make not an agreeable mixture with grandeur. Dissimilar emotions have a fine effect in a slow succession; but in a rapid succession which approaches to co-existence, they will not be relished."[1595] What pity is it, that the poet should here confute the critic, by doing what the critic, with his rules, teaches us cannot be done. Boileau, who was both poet and critic, had a clear view of this excellence in idea; while the mere critic had no idea of what had been clearly set before his eyes.
On peut être à la fois et pompeux et plaisant;
Et je haïs un sublime ennuyeux et pesant.
Ver. 37. Who saw its fires here rise, &c.] Sir Isaac Newton, in calculating the velocity of a comet's motion, and the course it describes, when it becomes visible in its descent to, and ascent from, the sun, conjectured, with the highest appearance of truth, that comets revolve perpetually round the sun, in ellipses vastly eccentrical, and very nearly approaching to parabolas. In which he was greatly confirmed, in observing between two comets a coincidence in their perihelions, and a perfect agreement in their velocities.
Ver. 45. vanity, or dress,] These are the first parts of what the poet, in the preceding line, calls the scholar's equipage of pride. By vanity, is meant that luxuriancy of thought and expression in which a writer indulges himself, to show the fruitfulness of his fancy or invention. By dress, is to be understood a lower degree of that practice, in amplification of thought and ornamental expression, to give force to what the writer would convey: but even this, the poet, in a severe search after truth, condemns; and with great judgment, conciseness of thought, and simplicity of expression, being as well the best instruments, as the best vehicles of truth. Shakespeare touches upon this latter advantage with great force and humour. The flatterer says to Timon in distress, "I cannot cover the monstrous bulk of their ingratitude with any size of words." The other replies, "Let it go naked; men may see't the better."
Ver. 46. Or learning's luxury, or idleness;] The luxury of learning consists in dressing up and disguising old notions in a new way, so as to make them more fashionable and palatable; instead of examining and scrutinizing their truth. As this is often done for pomp and show, it is called luxury; as it is often done too to save pains and labour, it is called idleness.
Ver. 47. Or tricks to show the stretch of human brain,] Such as the mathematical demonstration concerning the small quantity of matter; the endless divisibility of it, &c.
Ver. 48. Mere curious pleasure, or ingenious pain;] i.e. when admiration has set the mind on the rack.
