Show Summary Details


This chapter illustrates that the cosmos is a finite and stable structure surrounded by an infinite void. It also demonstrates that the Earth and the heavens are homocentric spherical bodies with corresponding zones of latitude. A cosmos is a construct formed from the heavens, the Earth, and the natural substances within them. If the extracosmic void is limited, and at all events enclosed by something, yet not enclosed by body, it will be enclosed by something incorporeal. The cosmos itself, being a body, necessarily has both an upwards and downwards [direction], as well as the remaining directions. The theory of Nature states that circumhabitants, antipodes, and contrahabitants must exist, since none of these [groups] are described by direct reports.

Keywords: cosmos; infinite void; Earth; heavens; extracosmic void; Nature
