Famous quotes containing the word parallelism:
“The secret of heaven is kept from age to age. No imprudent, no sociable angel ever dropt an early syllable to answer the longings of saints, the fears of mortals. We should have listened on our knees to any favorite, who, by stricter obedience, had brought his thoughts into parallelism with the celestial currents, and could hint to human ears the scenery and circumstance of the newly parted soul.”
—Ralph Waldo Emerson (1803–1882)
