"How could the rising of Mars at the moment of my birth affect me, then or now? I was born in a closed room. Light from Mars couldn't get in. The only influence of Mars which could affect me is its gravity, but the gravitational influence of the obstetrician was much larger than the gravitational influence of Mars. Mars is a lot more massive but the obstetrician was a lot closer."
