The more intense has been the religion of any period and the more profound has been the dogmatic belief, the greater has been the cruelty and the worse has been the state of affairs.

Very few men can be genuinely happy in a life involving continual self-assertion against the skepticism of the mass of mankind, unless they can shut themselves up in a coterie and forget the cold outer world. The man of science has no need of a coterie, since he is thought well of by everybody except his colleagues. The artist, on the contrary, is in the painful situation of having to choose between being despised and being despicable.

With subjectivity in philosophy, anarchism in politics goes hand in hand. Already during Luther's lifetime, unwelcome and unacknowledged disciples had developed the doctrine of Anabaptism, which for a time dominated the city of Munster. The Anabaptists repudiated all law since they held that good men will be guided at every moment by the Holy Spirit, who can not be bound by formulas. From this premise they arrive at communism and sexual promiscuity; they were therefore exterminated after a heroic resistance.

Respectability, regularity, and routine - the whole cast-iron discipline of a modern industrial society - have atrophied the artistic impulse, and imprisoned love so that it can no longer be generous and free and creative, but must be either stuffy or furtive.
