Famous quotes containing the word human:
“There is no God, no universe, no human race, no earthly life, no heaven, no hell. It is all a dream, a grotesque and foolish dream. Nothing exists but you. And you are but a thought—a vagrant thought, a useless thought, a homeless thought, wandering forlorn among the empty eternities!”
—Mark Twain [Samuel Langhorne Clemens] (1835–1910)
“My belief is that no being and no society composed of human beings ever did, or ever will, come to much unless their conduct was governed and guided by the love of some ethical ideal.”
—Thomas Henry Huxley (1825–95)
“While it is generally agreed that the visible expressions and agencies are necessary instruments, civilization seems to depend far more fundamentally upon the moral and intellectual qualities of human beings—upon the spirit that animates mankind.”
—Mary Ritter Beard (1876–1958)
