[Footnote: _And last association_, l. 93. The miseries and the felicities of life may be divided into those which arise in consequence of irritation, sensation, volition, and association; and consist in the actions of the extremities of the nerves of sense, which constitute our ideas; if they are much more exerted than usual, or much less exerted than usual, they occasion pain; as when the finger is burnt in a candle; or when we go into a cold bath: while their natural degree of exertion produces the pleasure of life or existence. This pleasure is nevertheless increased, when the system is stimulated into rather stronger action than usual, as after a copious dinner, and at the beginning of intoxication; and diminished, when it is only excited into somewhat less activity than usual, which is termed ennui, or irksomeness of life.] [Footnote: _Ideal ills_, l. 94. The tooth-edge is an instance of bodily pain occasioned by association of ideas. Every one in his childhood has repeatedly bit a part of the glass or earthen vessel, in which his food has been given him, and has thence had a disagreeable sensation in his teeth, attended at the same time with a jarring sound: and ever after, when such a sound is accidentally produced, the disagreeable sensation of the teeth follows by association of ideas; this is further elucidated in Zoonomia, Vol. I. Sect. XVI. 10.] "Here ragged Avarice guards with bolted door His useless treasures from the starving poor; Loads the lorn hours with misery and care, And lives a beggar to enrich his heir. 100 Unthinking crowds thy forms, Imposture, gull, A Saint in sackcloth, or a Wolf in wool. While mad with foolish fame, or drunk with power, Ambition slays his thousands in an hour; Demoniac Envy scowls with haggard mien, And blights the bloom of other's joys, unseen; Or wrathful Jealousy invades the grove, And turns to night meridian beams of Love! [Footnote: _Enrich his heir_, l. 100. Cum furor haud dubius, cum sit manifesta phrenitis, Ut locuples moriaris, egenti vivere fato. JUVENAL.] [Footnote: _A Wolf in wool_, l. 102. A wolf in sheep's clothing.] "Here wide o'er earth impetuous waters sweep, And fields and forests rush into the deep; 110 Or dread Volcano with explosion dire Involves the mountains in a flood of fire; Or yawning Earth with closing jaws inhumes Unwarned nations, living in their tombs; Or Famine seizes with her tiger-paw, And swallows millions with unsated maw.
