Famous quotes containing the word influences:
“Without looking, then, to those extraordinary social influences which are now acting in precisely this direction, but only at what is inevitably doing around us, I think we must regard the land as a commanding and increasing power on the citizen, the sanative and Americanizing influence, which promises to disclose new virtues for ages to come.”
—Ralph Waldo Emerson (1803–1882)
