Very often a capacity is made for something that is expressive, something that has a strong action, and if there were no such capacity then it would destroy all that is around it until it destroyed itself. The moon, therefore, is the capacity in which the strongest light of the sun functions. That is why it is so cooling to be in the moonlight, because the moon takes the light of the sun upon itself and burns itself; and by doing so it allows the horizon, the spheres, to be lighted while at the same time it is cool. It is just like a talkative person, someone who is very fond of speaking, who will go mad if he has no one near to listen to him.
