Famous quotes containing the words early, modern and/or period:
“The Americans never use the word peasant, because they have no idea of the class which that term denotes; the ignorance of more remote ages, the simplicity of rural life, and the rusticity of the villager have not been preserved among them; and they are alike unacquainted with the virtues, the vices, the coarse habits, and the simple graces of an early stage of civilization.”
—Alexis de Tocqueville (1805–1859)
“Whosoever, in writing a modern history, shall follow truth too near the heels, it may haply strike out his teeth.”
—Sir Walter Raleigh (1552–1618)
“We are in a period when old questions are settled and the new are not yet brought forward. Extreme party action, if continued in such a time, would ruin the party. Moderation is its only chance. The party out of power gains by all partisan conduct of those in power.”
—Rutherford Birchard Hayes (1822–1893)
