" The risings and settings of the sun, the moon, and the other heavenly bodies may come about from the lighting up and quenching of their fires…; for nothing in our sensory experience runs counter to this hypothesis. Or the said effects may be caused by the emergence of these bodies from a point above the earth and again by the earth’s position in front of them; for nothing in our sensory experience is against this.45 Here two alternative explanations of “risings and settings” are offered; both are of equal value and equally true, since neither is contradicted by anything in our experience. On the contrary, we have all seen fires die down from lack of fuel, and lights obscured or blacked out by objects coming in front of them. "
