Full Idea

It seems that it is possible for someone to learn to count intransitively without learning to count transitively. But not vice versa.

Gist of Idea

Someone can recite numbers but not know how to count things; but not vice versa

A Reaction

Benacerraf favours the priority of the ordinals. It is doubtful whether you have grasped cardinality properly if you don't know how to count things. Could I understand 'he has 27 sheep', without understanding the system of natural numbers?
