Part 5 (2/2)
How loves, and tastes, and sympathies commence From evanescent notices of sense?
How from the yielding touch and rolling eyes The piles immense of human science rise?-- With mind gigantic steps the puny Elf, And weighs and measures all things but himself!”
The indulgent Beauty hears the grateful Muse, Smiles on her pupil, and her task renews. 50 Attentive Nymphs in sparkling squadrons throng, And choral Virgins listen to the song; Pleased Fawns and Naiads crowd in silent rings, And hovering Cupids stretch their purple wings.
II. ”FIRST the new actions of the excited sense, Urged by appulses from without, commence; With these exertions pain or pleasure springs, And forms perceptions of external things.
Thus, when illumined by the solar beams, Yon waving woods, green lawns, and sparkling streams, In one bright point by rays converging lie 61 Plann'd on the moving tablet of the eye; The mind obeys the silver goads of light, And IRRITATION moves the nerves of sight.
[Footnote: _And Irritation moves_, l. 64. Irritation is an exertion or change of some extreme part of the sensorium residing in the muscles or organs of sense in consequence of the appulses of external bodies. The word perception includes both the action of the organ of sense in consequence of the impact of external objects and our attention to that action; that is, it expresses both the motion of the organ of sense, or idea, and the pain or pleasure that succeeds or accompanies it. Irritative ideas are those which are preceded by irritation, which is excited by objects external to the organs of sense: as the idea of that tree, which either I attend to, or which I shun in walking near it without attention. In the former case it is termed perception, in the latter it is termed simply an irritative idea.]
”These acts repeated rise from joys or pains, And swell Imagination's flowing trains; So in dread dreams amid the silent night Grim spectre-forms the shuddering sense affright; Or Beauty's idol-image, as it moves, Charms the closed eye with graces, smiles, and loves; 70 Each pa.s.sing form the pausing heart delights, And young SENSATION every nerve excites.
[Footnote: _And young Sensation_, l. 72. Sensation is an exertion or change of the central parts of the sensorium or of the whole of it, _beginning_ at some of those extreme parts of it which reside in the muscles or organs of sense.
Sensitive ideas are those which are preceded by the sensation of pleasure or pain, are termed Imagination, and const.i.tute our dreams and reveries.]
”Oft from sensation quick VOLITION springs, When pleasure thrills us, or when anguish stings; Hence Recollection calls with voice sublime Immersed ideas from the wrecks of Time, With potent charm in lucid trains displays Eventful stories of forgotten days.
Hence Reason's efforts good with ill contrast, Compare the present, future, and the past; 80 Each pa.s.sing moment, un.o.bserved restrain The wild discordancies of Fancy's train; But leave uncheck'd the Night's ideal streams, Or, sacred Muses! your meridian dreams.
[Footnote: _Quick Volition springs_, l. 73. Volition is an exertion or change of the central parts of the sensorium, or of the whole of it _terminating_ in some of those extreme parts of it which reside in the muscles and organs of sense.
The vulgar use of the word _memory_ is too unlimited for our purpose: those ideas which we voluntarily recall are here termed ideas of _recollection_, as when we will to repeat the alphabet backwards. And those ideas which are suggested to us by preceding ideas are here termed ideas of _suggestion_, as whilst we repeat the alphabet in the usual order; when by habits previously acquired B is suggested by A, and C by B, without any effort of deliberation. Reasoning is that operation of the sensorium by which we excite two or many tribes of ideas, and then reexcite the ideas in which they differ or correspond. If we determine this difference, it is called judgment; if we in vain endeavour to determine it, it is called doubting.
If we reexcite the ideas in which they differ, it is called distinguis.h.i.+ng. If we reexcite those in which they correspond, it is called comparing.]
[Footnote: _Each pa.s.sing moment_, l. 81. During our waking hours, we perpetually compare the pa.s.sing trains of our ideas with the known system of nature, and reject those which are incongruous with it; this is explained in Zoonomia, Sect.
XVII. 3. 7. and is there termed Intuitive a.n.a.logy. When we sleep, the faculty of volition ceases to act, and in consequence the uncompared trains of ideas become incongruous and form the farrago of our dreams; in which we never experience any surprise, or sense of novelty.]
”And last Suggestion's mystic power describes Ideal hosts arranged in trains or tribes.
So when the Nymph with volant finger rings Her dulcet harp, and shakes the sounding strings; As with soft voice she trills the enamour'd song, Successive notes, unwill'd, the strain prolong; 90 The transient trains a.s.sOCIATION steers, And sweet vibrations charm the astonish'd ears.
[Footnote: _a.s.sociation steers_, l. 91. a.s.sociation is an exertion or change of some extreme part of the sensorium residing in the muscles and organs of sense in consequence of some antecedent or attendant fibrous contractions. a.s.sociate ideas, therefore, are those which are preceded by other ideas or muscular motions, without the intervention of irritation, sensation, or volition between them; these are also termed ideas of suggestion.]
”ON rapid feet o'er hills, and plains, and rocks, Speed the scared leveret and rapacious fox; On rapid pinions cleave the fields above The hawk descending, and escaping dove; With nicer nostril track the tainted ground The hungry vulture, and the prowling hound; Converge reflected light with nicer eye The midnight owl, and microscopic fly; 100 With finer ear pursue their nightly course The listening lion, and the alarmed horse.
”The branching forehead with diverging horns Crests the bold bull, the jealous stag adorns; Fierce rival boars with side-long fury wield The pointed tusk, and guard with shoulder-s.h.i.+eld; Bounds the dread tiger o'er the affrighted heath Arm'd with sharp talons, and resistless teeth; The pouncing eagle bears in clinched claws The struggling lamb, and rends with ivory jaws; 110 The tropic eel, electric in his ire, Alarms the waves with unextinguish'd fire; The fly of night illumes his airy way, And seeks with lucid lamp his sleeping prey; Fierce on his foe the poisoning serpent springs, And insect armies dart their venom'd stings.
[Footnote: _The branching forehead_, l. 103. The peculiarities of the shapes of animals which distinguish them from each other, are enumerated in Zoonomia, Sect. x.x.xIX. 4.
8. on Generation, and are believed to have been gradually formed from similar living fibres, and are varied by reproduction. Many of these parts of animals are there shown to have arisen from their three great desires of l.u.s.t, hunger, and security.]
