Friedrich Nietzsche said this 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 whe na carriage goes past. I however am sitting in the carriage, and often I am the carriage itself.Ina man who thinks like this, the dichotomy between thinking and feeling, intellect and passion, has really disappeared. He feels his thoughts. He can fall in love with an idea. An idea can make him ill.
