 As we have seen, the existence of a connection between celestial and terrestrial events was admitted by most everybody, but not everybody agreed on the nature of this connection. Gersonides as well must account for the type of relation obtaining between celestial and terrestrial events. Having articulated the ordering power of the astral bodies, Gersonides describes in Milhamot V.3 the separate intellects and the spheres that they move. The main characteristic of the astral bodies is their luminosity (nitzutz). This luminosity affects their actions and effects (Wars, V.2.3, p. 137). Gersonides is very much aware of the problem of accounting for how the astral bodies can affect actions at a distance. The sun, for example, functions as a paradigm for action at a distance. Once we understand, Gersonides claims, how the activity of heating reaches earth from the sun, we can understand how the particular activities of the other stars reach the sublunar realm as well. By explaining the efficient cause as the light or radiation of the stars, Gersonides can account for weak or strong effects. As Langermann has pointed out, Gersonides’ account furnishes the basis for the introduction of astrological causation into natural philosophy.
