The Era of the Seventh Mental Structure saw the rise of a civilization of unparalleled liberty, justice, and magnificence. So great were the intellectual and material accomplishments of this civilization that she came to be called the Golden Oecumene, and the time of her greatest flowering was honored with the name the Golden Age. Physically, the Golden Oecumene extended from engineering stations within the solar photosphere to remote outposts, hermitages, and astronomical observatories within the Oort cloud beyond Neptune. Intellectually, the libraries and active mental configurations of the Sophotech segment of the population embodied uncountable quadrillions of units of information, infinitesimal processing times and nonsequential semantic and symbolic arrangements no human mind, no matter how augmented, could understand. There were isolated areas within the Solar System that did not recognize the political authority of the administration of the Foederal Oecumenical Commonwealth, such as certain Oort cloud hermitages, or Talaimannar on the island of Ceylon; but despite their political separation, such minor enclaves were still part of the philosophical, linguistic, and cultural milieu of the Golden Oecumene.
