His pow'rs in equal ranks, and fair array. But with th' occasion and the place comply, Conceal his force, nay seem sometimes to fly. Those oft are stratagems which error seem, Nor is it Homer nods, but we that dream. 180 Still green with bays each ancient Altar stands, Above the reach of sacrilegious hands; Secure from Flames, from Envy's fiercer rage, Destructive War, and all-involving Age. See, from each clime the learn'd their incense bring! 185 Hear, in all tongues consenting Paeans ring! In praise so just let ev'ry voice be join'd, And fill the gen'ral chorus of mankind. Hail, Bards triumphant! born in happier days; Immortal heirs of universal praise! 190 Whose honours with increase of ages grow, As streams roll down, enlarging as they flow; Nations unborn your mighty names shall sound, And worlds applaud that must not yet be found! Oh may some spark of your celestial fire, 195 The last, the meanest of your sons inspire, (That on weak wings, from far, pursues your flights; Glows while he reads, but trembles as he writes) To teach vain Wits a science little known, T' admire superior sense, and doubt their own! 200 Of all the Causes which conspire to blind Man's erring judgment, and misguide the mind, What the weak head with strongest bias rules, Is _Pride_, the never-failing voice of fools. Whatever nature has in worth denied, 205 She gives in large recruits of needful pride; For as in bodies, thus in souls, we find What wants in blood and spirits, swell'd with wind: Pride, where wit fails, steps in to our defence, And fills up all the mighty Void of sense. 210 If once right reason drives that cloud away, Truth breaks upon us with resistless day. Trust not yourself; but your defects to know, Make use of ev'ry friend--and ev'ry foe. A _little learning_ is a dang'rous thing; 215 Drink deep, or taste not the Pierian spring. There shallow draughts intoxicate the brain, And drinking largely sobers us again. Fir'd at first sight with what the Muse imparts, In fearless youth we tempt the heights of Arts, 220 While from the bounded level of our mind Short views we take, nor see the lengths behind; But more advanc'd, behold with strange surprise New distant scenes of endless science rise! So pleas'd at first the tow'ring Alps we try, 225 Mount o'er the vales, and seem to tread the sky, Th' eternal snows appear already past, And the first clouds and mountains seem the last; But, those attain'd, we tremble to survey The growing labours of the lengthen'd way, 230 Th' increasing prospect tires our wand'ring eyes, Hills peep o'er hills, and Alps on Alps arise!
