Everybody could become a Roman citizen or, finally, was declared to be such by birth. This citizenship was a tremendous equalizing step. Further, the women, slaves and children, who in the old Roman law were the least regarded and developed human beings, became equalized by the laws of the Roman emperors.
This was done, moreover, not by Christianity, but by the Stoics, who derived the idea from the belief in the universal logos in which everyone participates. (Of course, Christianity has another foundation for the same idea: human beings are the children of God who is their Father.) Thus the Stoics conceived of the idea of a world state embracing the whole world, based on the common rationality of everybody.
Now this certainly was something in which Christianity could enter and develop. The difference was that the Stoics did not know the concept of sin. They knew the concept of foolishness, but not of sin. Therefore, STOIC SALVATION is salvation through reaching wisdom. CHRISTIAN SALVATION was a salvation through reaching Divine grace. And these two things still fight with each other in our days.
There was another reality which was taken over by the Christian Church, and for which pure philosophers coming from Europe have often a great contempt, while I think Americans should not have contempt at all, because in this as in so many respects, they are basically ancient Romans – namely, what is called eclecticism, from a Greek word meaning: choosing some possibilities out of many. The eclectics were philosophers but they were not originally creative philosophers, as the Greeks were, who created their system on which basis the schools worked. The Roman thinkers, politicians, and statesmen were often the same persons, as in England: in this I think England is superior to America; I hope we will soon have in this country philosophers who are statesmen, as we had it in England, and in ancient Rome. — These people were eclectics; they did not create new systems. What they did, e.g., Cicero, was to choose the most important concepts from the classical Greek systems which were pragmatically useful for a Roman citizen. That which gave the best way of living pragmatically as a Roman citizen, as a citizen of the world state, was taken from the different philosophies. For this reason the following ideas, which you can recognize very much in popular political speeches in this country today, are those chosen from a pragmatic point of view: the idea of PROVIDENCE, which gives some kind of feeling of safety to the life of the people; the idea of GOD as an innate idea in everybody, which induces fear of God, and discipline; the idea of MORAL FREEDOM AND RESPONSIBILITY, which makes it possible to educate and to uphold responsibility for moral failures; and finally the idea of IMMORTALITY, which threatens with another world those who escape punishment in this world.
