Matheology § 231
One philosophically important way in which numbers and sets, as they are naively understood, differ is that numbers are physically instantiated in a way that sets are not. Five apples are an instance of the number 5 and a pair of shoes is an instance of the number 2, but there is nothing obvious that we can analogously point to as an instance of, say, the set {{/0}}.
