Of hearing, from the life that fills the flood, 215 To that which warbles through the vernal wood? 'Twixt that, and Reason, what a nice barrier?

It is probable the ftory of the jackall's hunting for the lion, was occafioned by the observation of this defect of fcent in that terrible animal. P. VER. 224. For ever fep'rate, &c.] Near, by the fimilitude of the operations; Separate by the immense difference in the nature of the powers. W. VER. 226. What thin partitions, &c.] So thin, that the Atheiftic Philofophers, as Protagoras, held that THOUGHT was only SENSE; and from thence concluded, that every imagination or opinion of every man was true: Πᾶσα Φανασία ἐςὶν ἀληθής. But the Poet determines more philofophically; that they are really and effentially different, how thin foever the partition be by which they are divided. Thus, (to illuftrate the truth of this obfervation,) when a geometer confiders a triangle, in order to demonftrate the equality of its three angles to two right ones, he has the picture or image of some sensible triangle in his mind, which is sense; yet notwithstanding, he must needs have the motion or idea of an intellectual triangle likewise, which is thought; for this plain reafon, because every image or picture of a triangle must needs be obtufangular, or rectangular, or acutangular; but that which, in his mind, is the fubject of his propofition is the ratio of a triangle, undetermined And Middle natures, how they long to join, Without this juft gradation, could they be The pow'rs of all fubdu'd by thee alone, Is not thy Reafon all thefe pow'rs in one? 230 VIII, See, through this air, this ocean, and this earth, All matter quick, and bursting into birth, Above, how high, progreffive life may go! 235 VER. 238.

On this account it was that Ariftotle faid, Νοηματα τιν διοίσει, τὰ μὴ Φαντάσματα εἶναι, η δι ταῦτα φαλάσματα, ἀλλ ̓ ἐκ ἄνευ φωνάσματων. The conceptions of the mind differ fomewhat from fenfible images; they are not fenfible images, and yet not quite free or disengaged from fenfible images. VER. 232. Is not thy Reafon] "Such then is the admirable diftribution of nature, her adapting and adjusting not only the stuff or matter to the shape itself and form, to the circumftance, place, element, or region; but alfo the affections, appetites, fenfations, mutually to each other, as well as the matter, form, action, and all befides; all managed for the beft, with perfect frugality and just reserve: profufe to none, but bountiful to all: never employing in one thing more than enough; but with exact œconomy retrenching the fuperfluous, and adding force to what is principal in every thing: And is not thought and reafon principal in man? would we have no reserve for thefe; no faving for this part of his engine?" Shaftsbury, in the Moralift, vol. ii. p. 99. VER. 235. Above, how high,] This is a magnificent paffage. Thomfon had before faid, in Summer, v. 333.

VER. 244. The great fcale's deftroy'd:] All that can be faid of the fuppofition of a scale of beings, gradually defcending from perfection to non-entity, and complete in every rank and degree, is to be found in the third chapter of King's Origin of Evil, and in a note of the Archbishop, marked G, p. 137. of Law's tranflation, ending with these emphatical words: "Whatever fyftem God had chofen, all creatures in it could not have been equally perfect; and there could have been but a certain determinate multitude of the most perfect; and, when that was completed, there would have been a station for creatures less perfect, and it would still have been an inftance of goodness to give them a being as well as others." VER. 245. From Nature's chain] Almoft the words of Marcus Antoninus, l. v. c. 8.; as alfo v. 265. from the fame.

It is obfervable, that these noble lines were added after the first folio edition. It is a pleafing and useful amusement to trace out the alterations that a great and correct writer gradually makes in his works. At first it ran, How inftinct varies! What a hog may want And again; What the advantage if his finer eyes Study a mite, not comprehend the skies. Which lines at present stand thus: How instinct varies in the growling fwine, Compar'd, half-reas'ning Elephant, with thine: No felf-confounding faculties to share, At prefent; No pow'rs of body or of foul to fhare, But what his nature and his ftate can bear. It appeared at first very exceptionably; Expatiate far o'er all this fcene of Man, Which contradicted his whole system, and it was altered to, All this dread ORDER break for whom? for thee?

All are but parts] These are lines of a marvellous energy and clofenefs of expreffion. They are exactly like the old Orphic verfes quoted in Ariftotle, De Mundo. Edit. Lugd. folio, 1590, p. 378.; and line 289 as minutely refembles the doctrine of the fublime hymn of Cleanthes the Stoic; not that I imagine Pope or Bolingbroke ever read that hymn, especially the latter, who was ignorant of Greek. VER. 268. Whose body Nature is, &c.] Mr. de Croufaz remarks, on this line, that "A Spinozist would exprefs himself in this manner." I believe he would; for so the infamous Toland has done, in his Atheist's Liturgy, called PANTHEISTICON: But fo would St. Paul likewife, who, writing on this fubject, the omnipresence of God in his Providence, and in his Substance, says, in the words of a pantheistical Greek Poet, In him we live, and move, and have our being; i. e. we are parts of him, his offspring: And |
