Famous quotes containing the word universe:
“The universe appears to me like an immense, inexorable torture-garden.... Passions, greed, hatred, and lies; law, social institutions, justice, love, glory, heroism, and religion: these are its monstrous flowers and its hideous instruments of eternal human suffering.”
