The Summary of Physics Restored

73Water is not raised into vapour by heat alone, nor does it gather into cloud by cold alone. The powers of the sun and stars contribute greatly to both, not only by multiplying the elements' powers but also by attracting and retaining moisture to a greater or lesser degree through a certain magnetic force, according to their different positions and the configuration of heaven. Hence we observe differences in the constitution of years and seasons. For that mass of waters is held poised aloft not by cold or the air's solidity alone, but by the powerful command of the higher bodies.
