| I dont' think I agree that something has to belong to itself to exist. However, something can belong to a set where there is only one elemnt and that element is itself.
A= an item with properties
B={A}= the set of elements that have exactly the same properties as A
This is not the same as saying A belongs to itself. Rather it says that A belongs to a set where all the elements have exactly the same properties as A. B is a set or a grouping of elements, it does not equal it's elements. |
