摘要：The article discusses how the empty set reflects reality. Every possible world is observed as a set of objects which are holders of various properties. By applying the Löwenheim-Skolem theorem, every world is reduced to the set of natural numbers. Furthermore, it is shown that each natural number can be presented as a reflection of the empty set. Finally, the empty set concept is used to support some basic ideas of neoplatonic and Christian philosophy.
