Unhappiness. There are all kinds of unhappy people in the world. I suppose it would be no exaggeration to say that the world is composed entirely of unhappy people. But those people can fight their unhappiness with society fairly and squarly, and society for its part easily understands and sympathizes with such struggles. My unhappiness stemmed entirely from my own vices, and I had no way of fighting anybody.
