Barbault’s Cyclic Index of Global Tension, Conflict, and War from 1900 to 2100.
André
Barbault’s Cyclic Index of Global Tension, Conflict, and War represents
a composite of the angular distances among the five outer planets.
Within the framework of mundane astrology, Pluto, Neptune, and Uranus
are identified as "collective planets," as their slow-moving cycles
correspond to broad cultural and historical epochs. In contrast, Saturn
and Jupiter are categorized as "social planets," which relate more
directly to sociopolitical and economic developments.
