You don't believe that your friend could ever do anything great. You despise yourself in secret, even – no, especially – when you stand on your dignity; and since you despise yourself, you are unable to respect your friend. You can't bring yourself to believe that anyone you have sat at table with, or shared a house with, is capable of great achievement. That is why all great men have been solitary. It is hard to think in your company, little man. One can only think 'about' you, or 'for your benefit', not 'with' you, for you stifle all big, generous ideas.
