Famous quotes containing the word nature:
“Without any extraordinary effort of genius, I have discovered that nature was the same three thousand years ago as at present; that men were but men then as well as now; that modes and customs vary often, but that human nature is always the same. And I can no more suppose, that men were better, braver, or wiser, fifteen hundred or three thousand years ago, than I can suppose that the animals or vegetables were better than they are now.”
—Philip Dormer Stanhope, 4th Earl Chesterfield (1694–1773)
“From cradle to grave this problem of running order through chaos, direction through space, discipline through freedom, unity through multiplicity, has always been, and must always be, the task of education, as it is the moral of religion, philosophy, science, art, politics and economy; but a boy’s will is his life, and he dies when it is broken, as the colt dies in harness, taking a new nature in becoming tame.”
—Henry Brooks Adams (1838–1918)
“Wars will remain while human nature remains. I believe in my soul in cooperation, in arbitration; but the soldier’s occupation we cannot say is gone until human nature is gone.”
—Rutherford Birchard Hayes (1822–1893)
