emotions caused the individual and society to be weak spiritually and did not help with survival in the harsh environment of this world.

The explosive development of technology was analogous to the grown of cancer cells, and the results would be identical: the exhaustion of all sources of nourishment, the destruction of organs, and the final death of the host body. He advocated abolishing crude technologies such as fossil fuels and nuclear energy and keeping gentler technologies such as solar power and small-scale hydroelectric power.

Suppose a vast number of civilizations are distributed throughout the universe, on the order of the number of detectable stars. Lots and lots of them. The mathematical structure of cosmic sociology is far clearer than that of human sociology. The factors of chaos and randomness in the complex makeups of every civilized society in the universe get filtered out by the immense distance, so those civilizations can act as reference points that are relatively easy to manipulate mathematically. First: Survival is the primary need of civilization. Second: Civilization continuously grows and expands, but the total matter in the universe remains constant. One more thing: To derive a basic picture of cosmic sociology from these two axioms, you need two other important concepts: chains of suspicion and the technological explosion.
