Behold the child, by Nature's kindly law, Pleased with a rattle, tickled with a straw; Some livelier plaything gives his youth delight, A little louder, but as empty quite; Scarfs, garters, gold, amuse his riper stage, And beads and prayer-books are the toys of age. Pleased with this bauble still, as that before, Till tired he sleeps, and life's poor play is o'er.
See skulking Truth to her old cavern fled, Mountains of Casuistry heap'd o'er her head! Philosophy, that lean'd on Heav'n before, Shrinks to her second cause, and is no more. Physic of Metaphysic begs defence, And Metaphysic calls for aid on Sense! See Mystery to Mathematics fly!
First follow Nature, and your judgment frame
By her just standard, which is still the same:
Unerring nature, still divinely bright,
One clear, unchanged, and universal light,
Life, force, and beauty must to all impart,
At once the source, and end, and test of art.
The meeting points the sacred hair dissever From the fair head, forever, and forever! Then flashed the living lightning from her eyes, And screams of horror rend th' affrighted skies.
