A /countable set/ S (as defined in the context of set theory) is NOT "countable" because it can be counted (and/or there is someone who can count its elements), but because there is an injective function f such that f maps IN onto S.
Why can't it be counted? Why cannot every argument n be inserted in the function f(n)?
Why don't most set theorists understand that both has the same reason?
Alas, most set theorists do not even grasp that not every argument can be inserted.
