In particular it doesn't "belong" (i.e. it is not an element) of itself, since by definition, it doesn't have any elements. similarly it doesn't belong to the set {1} that contains just one element, the natural number 1. Etc. A slight correction to the last sentence: the empty set is a subset of any set, but it doesn’t belong to every set.
