"In some socialist states well-performed work is rewarded with moral stimulants instead of material ones. However, the moral stimulants cannot be explained by materialistic philosophy. It is the same case with the appeals for humanism, justice, equality, freedom, human rights, and so forth, which are all of religious origin. Certainly, everybody has the right to live as he thinks best, including the right not to be consistent with his own pattern. Still, to understand the world correctly, it is important to know the true origin of meaning and of the ideas ruling the world."
