This chapter shows that the Moon is illuminated neither by inherent light, nor by reflection, but by the mingling of the Sun's light with the Moon's body. Several theories concerning the illumination of the Moon are presented. In addition, the impossibility of the Moon sending out light by reflection is outlined by arguments. The Sun is eclipsed through being obstructed by the Moon; certainly this happens only at their conjunction. Also, a solar eclipse is a condition affecting not the deity itself, but human's line of sight. A lunar eclipse, by contrast, is a condition affecting the deity itself, since the Moon, whenever it falls into the Earth's shadow, is deprived of the Sun's light and plunged into darkness.

Keywords:   Moon, Sun, solar eclipse, lunar eclipse, light, reflection, illumination
