“Could it be that those who were reared in the postwar years really were spoiled, as we used to hear? Did a child-centered generation, raised in depression and war, produce a self-centered generation that resents children and parenthood?”
—C. John Sommerville (20th century)
“...that absolutely everything beloved and cherished of the bourgeoisie, the conservative, the cowardly, and the impotent—the State, family life, secular art and science—was consciously or unconsciously hostile to the religious idea, to the Church, whose innate tendency and permanent aim was the dissolution of all existing worldly orders, and the reconstitution of society after the model of the ideal, the communistic City of God.”
—Thomas Mann (1875–1955)
