Conviviality is a wicked lady who forcibly corrupts morals and indoctrinates into vice. The one who coexists buys this lady using his own freedom as currency. He becomes someone worse, for sure. In this, modern psychology is infallible: there is a veiled convivial agreement that implies actions which, if not fulfilled, generate individual and collective discomfort. Moral evolution requires a break from this agreement, because it consists of a reaction to worldly instinct. Virtue, although practiced in the world, can only be conceived in solitude.
