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.
