Brains in a vat / Evans: there is no truth-maker - if the subject learns the truth, it would have to consider "nowhere" - meaningless to identify themselves: "I am a brain" - body and localization crucial - different: brain transplant : there is a history here: the brain would be experienced as "somewhere".
