Famous quotes containing the word modern:
“The ancients of the ideal description, instead of trying to turn their impracticable chimeras, as does the modern dreamer, into social and political prodigies, deposited them in great works of art, which still live while states and constitutions have perished, bequeathing to posterity not shameful defects but triumphant successes.”
—Herman Melville (1819–1891)
