Hilary Putnam's 'Brains In Vats': An Analysis

In this essay I will be explaining Hilary Putnam 's "Brains in Vats" theory, as well as giving my own personal opinion if Putnam has solved the theory. Hilary Putman, who taught Philosophy at Harvard University (page 397, Brains in Vats), wrote an argument to clear if we are really BIV 's (Brains in vats). He starts off his argument by clearing up what a "causal connection" is. If an ant were to accidentally outline the picture of Winston Churchill, very many people would not claim that the ant purposely referred to Churchill. Putnam states that "nothing physical has intentionality" (page 398, paragraph 1, "Brains in Vats", Hilary Putnam). Putnam goes on to say that he wants us to imagine what that we are brains in vats hooked up to a …show more content…

Even though Putnam shows that a brain in a vat would refer to different things then an embodied brain, there are still some points that I think proves that we could be brains in a vat and not even know it. In Putnam 's theory we have two different perspectives. The perspective of the evil scientist outside of the vat, and the envatted brains perspective inside the vat. If the evil scientist says "that’s a tree", that statement is true to the evil scientist. If the scientist relays this information to the envatted brain through the computer and the envatted brain says "that’s a tree", the statement would be false. The envatted brain is referring to a simulation of a tree and not the actual tree the scientist was referring too. The envatted brain only can refer to virtual objects in its own "vat language" but cannot refer to real objects like the evil scientist …show more content…

Suppose the envatted brain is controlled by an automatic machine tending to the vats. If we look at this we see two different objects here- the brain and the automatic machine-and both get their information internally. From the perspective of the machine, if the machine says "that’s a tree" its statement would be true to the machine because there are no external connections or references (evil scientist) to say otherwise or compare too. From the envatted brains perspective, if the machine was to relay the information to the brain stating "that’s a tree", and the envatted brain then says "that’s a tree" the statement would also be true. The machines version of a tree would be true to the machine and its relaying that information to the envatted brain which then would refer to a tree. They are both referring to a simulation of a tree, which would be a "true" reference because that would be the only tree both the machine and the envatted brain knows. You could not say the envatted brain was not referring to objects "truly" if the envatted brain was in fact referring rightfully to its external machine. So in a virtual "brains in a vat world", an envatted brain and the machine it was hooked up to and running off of, would only know how to refer to anything as virtual (But it would be real to both of them). If we did live in a world of only envatted brains that referred
