The title Astrologia Racional is a manifesto in itself. In Weiss’s view, a "rational" astrology is one that functions according to the laws of cause and effect. He rejected the idea that planetary rays "beam" supernatural forces into humans. Instead, he proposed that the planets act as indicators—cosmic clocks that mark the timing of terrestrial events with mathematical precision.
