Anti-theses.- The most senile thing ever thought about man is contained in the celebrated saying 'the ego is always hateful'; the most childish is the even more celebrated 'love thy neighbor as thyself'. - In the former, knowledge of human nature has ceased, in the latter it has not yet even begun.
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.

He feels his thoughts. He can fall in love with an idea. An idea can make him ill.
