It’s funny how people post this sarcastically. Think about it — a planet is an object of unimaginably tremendous mass. We already know that planets have (1) gravity wells and (2) electro-magnetic fields.
Who’s to say that they don’t have all sorts of other auras and effects at levels we don’t comprehend yet? We live in a universe where particles influence each other at infinite distance and even across time. I find it completely believable, actually mundane, that the positions and angles of the planets could have a tremendous and determinant effect on personality, but more importantly, macro-historical waves of revolution and liberation, war and reaction, invention and enlightenment, and religious movements. Read Cosmos and Psyche by Richard Tarnas, it’s like astrology written for historians and marxists.
