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}}.
