Brain-in-a-vat Guide, Meaning , Facts, Information and Description
In epistemology, the brain-in-a-vat thought experiment countenances the notion that you are actually just a disembodied brain in some sort of suspension, attached by wires to a supercomputer that provides electrical input that simulates the existence of a real world, and responds to the brain's output in an appropriate way--a sort of simulated reality.That we are brains in vats is never seriously contended, but rather offered as an argument for philosophical skepticism toward empiricism. The argument is: if you cannot be sure that you aren't a brain in a vat, how can you have any certain knowledge at all? After all, it seems that if you really were in this situation, the vast majority of your beliefs would be false.
It is thus very similar to Descartes' argument (in Meditations on First Philosophy) that centred around the possibility that an evil demon was controlling his every experience.
Hilary Putnam claims to have refuted the brain-in-a-vat thought experiment as inconsistent.
The status of the human race in the movie, The Matrix, is a weak reference to the brain-in-a-vat theory, though in that case entire bodies were preserved, rather than just brains. If the only true mind in existence was Neo (the movie's main character) and all other humans were merely computer programs, this would be a more perfect example.
