Famous quotes containing the word abundance:
“Here commences what was called, twenty years ago, the best timber land in the State. This very spot was described as “covered with the greatest abundance of pine,” but now this appeared to me, comparatively, an uncommon tree there,—and yet you did not see where any more could have stood, amid the dense growth of cedar, fir, etc.”
—Henry David Thoreau (1817–1862)
“Civilization does not engross all the virtues of humanity: she has not even her full share of them. They flourish in greater abundance and attain greater strength among many barbarous people. The hospitality of the wild Arab, the courage of the North American Indian, and the faithful friendships of some of the Polynesian nations, far surpass any thing of a similar kind among the polished communities of Europe.”
—Herman Melville (1819–1891)
“The family that perseveres in good works will surely have an abundance of blessings.”
—Chinese proverb.
