As soon as he reflected seriously he was convinced of the existence of God and immortality, and at once he instinctively said to himself: "I want to live for immortality, and I will accept no compromise." In the same way, if he had decided that God and immortality did not exist, he would have at once become an atheist and a socialist. For socialism is not merely the labor question, it is before all things the atheistic question, the question of the form taken by atheism to-day, the question of the tower of Babel built without God, not to mount to heaven from earth but to set up heaven on earth.
