Hi! Thank you so much for your peer review, in response to your question about BIV and how when the "brain" inside the "vat" refers to itself as a brain in the vat, the argument that Putnam lays out explains how the pure BIV will not be able to refer back to the real world because it has no knowledge of the real world 'brain' and 'vat' since it has only ever been exposed to its own reality. Although within the BIV world it has its own definition of a brain and vat, when it is trying to refer back to the real world, it is unable to, due to the lack of causal constraint. Of course, there have been counterarguments made to Putnam's argument, and there has also been incoherence that has been pointed out. I do hope that my explanation helped clear up some of your concerns! Nootiebeans (talk) 20:02, 6 October 2021 (UTC)Nootiebeans
