Friedrich Nietzsche Quote

You know these things as thoughts, but your thoughts are not your experiences, they are an echo and after-effect of your experiences: as when your room trembles when a carriage goes past. I however am sitting in the carriage, and often I am the carriage itself."

As quoted in the Introduction of Thus Spoke Zarathustra (Penguin Classics, tr. Reg Hollingdale), p. 12
