9. Brain in The Vat
This thought experiment is closely related to solipsism with a few simple modifications. For one, it brings external beings into the scenario. Basically, the fact that we have no way of looking at things through the existence of other beings makes verifying anything outside of our own reality fairly impossible. The only things we can perceive exist within our own consciousness. Hence the scenario of being a “brain in a vat” i.e. what if our brains are sitting in a jar right now and being experimented on by scientists or aliens or weird creatures from the future? Would we ever know? What if the reality you have right now is just a vivid dream working inside your consciousness? The truth is, there would be no way of knowing for sure.
If this sounds exactly like the Matrix, well, that’s because the Matrix movies were actually based on the “brain in the vat” theory, as in we’re all just dreaming this life away in glass tubes.
