 In Milhamot V.2.8 Gersonides lays out six astrological principles that affect his general cosmological scheme. These can be summarized as follows. First, each astral body exercises a different influence specific to it. Second, astral influence depends upon its position in the zodiac (galgal hamazalot). Third, the longer a star stays in one place in the zodiac, the greater its effect because of the strength of its luminosity. Fourth, astral influence is dependent upon its inclination to the north or to the south; its effect will be strongest when it is in the middle, as evidenced by the sun, whose heat is strongest when it is at the Tropic of Cancer as opposed to being at the Tropic of Capricorn. Fifth, the greater the radiation or luminosity of a star, the stronger its influence. And finally, the closer to earth a star is, the stronger will be its influence (Wars, V.2.8, p. 207–8). These principles function as the underpinnings of his general astronomy as well.
