  The view of conscious content as intrinsically determined and internally self-evident is sometimes supported by appeals to brain in the vat intuitions, which make it seem that the envatted brain's conscious mental states would keep all their normal intentional contents despite the loss of all their normal causal and informational links to the world (Horgan and Tienson 2002). There is continued controversy about such cases and about competing internalist (Searle 1992) and externalist views (Dretske 1995) of conscious intentionality.
