274 psl. - Are not the mountains, waves, and skies, a part Of me and of my soul, as I of them?
21 psl. - AH ! who can tell how hard it is to climb The steep where Fame's proud temple shines afar; Ah! who can tell how many a soul sublime Has felt the influence of malignant star, And waged with Fortune an eternal war; Check'd by the scoff of Pride, by Envy's frown, And Poverty's unconquerable bar, In life's low vale remote has pined alone, Then dropt into the grave, unpitied and unknown...
322 psl. - Reading maketh a full man, conference a ready man, and writing an exact man. And therefore if a man write little he had need have a great memory: if he confer little he had need have a present wit, and if he read little he had need have much cunning to seem to know that he doth not. Histories make men wise, poets witty, the mathematics subtle, natural philosophy deep, moral grave, logic and rhetoric able to contend,
363 psl. - Is there, in human form, that bears a heart — A wretch ! a villain ! lost to love and truth ! That can, with studied, sly, ensnaring art, Betray sweet Jenny's unsuspecting youth? Curse on his perjur'd arts ! dissembling smooth ! Are honour, virtue, conscience, all exil'd?
422 psl. - But hark ! a rap comes gently to the door ; Jenny, wha kens the meaning o' the same, Tells how a neebor lad cam' o'er the moor, To do some errands, and convoy her hame. The wily mother sees the conscious flame Sparkle in Jenny's e'e, and flush her cheek ; With heart-struck anxious care, inquires his name, While Jenny hafflins is afraid to speak : Weel pleased the mother hears it's nae wild, worthless rake. Wi...
415 psl. - Brethren, if any of you do err from the truth, and one convert him, let him know, that he *which converteth the sinner from the error of his way, shall save a soul from death, and shall hide a multitude of sins.
400 psl. - OH for a lodge in some vast wilderness, Some boundless contiguity of shade, Where rumour of oppression and deceit, Of unsuccessful or successful war, Might never reach me more.
415 psl. - To sit on rocks, to muse o'er flood and fell, To slowly trace the forest's shady scene, Where things that own not man's dominion dwell, And mortal foot hath ne'er, or rarely, been ; To climb the trackless mountain all unseen, With the wild flock that never needs a fold ; Alone o'er steeps and foaming falls to lean ; This is not solitude ; 'tis but to hold Converse with Nature's charms, and view her stores unroll'd.
326 psl. - Their blood is shed In confirmation of the noblest claim — Our claim to feed upon immortal truth, To walk with God, to be divinely free, To soar, and to anticipate the skies.
282 psl. - Yet when I approach Her loveliness, so absolute she seems And in herself complete, so well to know Her own, that what she wills to do or say, Seems wisest, virtuousest, discreetest, best.
