Full Idea
If the content of a concept is its reference, we can stop worrying about Twin Earth. If there are no senses, there is no question of whether my twin and I have the same WATER concept. Our WATER concepts aren't even coextensive.
Gist of Idea
If concept content is reference, then my Twin and I are referring to the same stuff

A Reaction
This seems like a neat solution. So do 'tap water' and 'holy water' have the same content to a Christian and non-Christian, when they co-refer to the contents of the font?
