If we look back to the historical sequence of world concepts, the theory of natural law will prove to be a paraphrase of Christian spiritualism freed from its crude mysticism. The Gospels proclaimed to the slave that he had just the same soul as the slave-owner, and in this way established the equality of all men before the heavenly tribunal. In reality, the slave remained a slave, and obedience became for him a religious duty. In the teaching of Christianity, the slave found an expression for his own ignorant protest against his degraded condition. Side by side with the protest was also the consolation. Christianity told him:--"You have an immortal soul, although you resemble a pack-horse." Here sounded the note of indignation. But the same Christianity said:--"Although you are like a pack-horse, yet your immortal soul has in store for it an eternal reward." Here is the voice of consolation. These two notes were found in historical Christianity in different proportions at different periods and amongst different classes. But as a whole, Christianity, like all other religions, became a method of deadening the consciousness of the oppressed masses. Natural law, which developed into the theory of democracy, said to the worker: "all men are equal before the law, independently of their origin, their property, and their position; every man has an equal right in determining the fate of the people." This ideal criterion revolutionized the consciousness of the masses in so far as it was a condemnation of absolutism, aristocratic privileges, and the property qualification. But the longer it went on, the more it sent the consciousness to sleep, legalizing poverty, slavery and degradation: for how could one revolt against slavery when every man has an equal right in determining the fate of the nation?
