  There’s a more direct way that the intrinsic surrogates might secure the efficacy of content: perhaps the surrogate properties are content, or rather a kind of content. Distinguish narrow from broad content. Think of narrow content as the content of a representational state of mind minus its “broad” components. Consider Lilian (or Lilian’s brain) and an intrinsically indiscernible brain in a vat wired to a supercomputer. Grant that Lilian and the envatted brain entertain intrinsically indiscernible thoughts with utterly different representational contents. Now imagine that we could abstract a common element from the contents of Lilian’s and the brain’s intrinsically indiscernible thoughts. This element is their narrow content. Because narrow content is something all intrinsic duplicates must have in common, the hope is that such content could be the very intrinsic properties that produce behavior.
