During the dispensation of a Planetary Prince, primitive man reaches the limit of natural evolutionary development, and this biologic attainment signals the System Sovereign to dispatch to such a world the second order of sonship, the biologic uplifters. These Sons, for there are two of them—the Material Son and Daughter—are usually known on a planet as . Fallacious complacence about Planetary Defense. “.
