Text of the page (random words):
er argued that the hypothetical machine could be made to also replicate those types of inputs argument from externalism edit a second argument deals directly with the stimuli coming into the brain this is often referred to as the account from externalism or ultra externalism 10 in the biv the brain receives stimuli from a machine in an embodied brain however the brain receives the stimuli from the sensors found in the body via touching tasting smelling etc which receive their input from the external environment this argument oftentimes leads to the conclusion that there is a difference between what the biv is representing and what the embodied brain is representing this debate has been hashed out but remains unresolved by several philosophers including uriah kriegel 11 colin mcginn 12 and robert d rupert 13 and has ramifications for philosophy of mind discussions on but not limited to representation consciousness content cognition and embodied cognition 14 argument from incoherence edit a third argument against biv comes from a direction of incoherence which was presented by the philosopher hilary putnam he attempts to demonstrate this through the usage of a transcendental argument in which he tries to illustrate that the thought experiment s incoherence lies on the basis that it is self refuting 15 this relationship is further defined through a theory of reference that suggested reference can not be assumed and words are not automatically intrinsically connected with what it represents this theory of reference would later become known as semantic externalism this concept is further illustrated when putnam establishes a scenario in which a monkey types out hamlet by chance however this does not mean that the monkey is referring to the play because the monkey has no knowledge of hamlet and therefore can not refer back to it 16 he then offers the twin earth example to demonstrate that two identical individuals one on the earth and another on a twin earth may possess the exact same mental state and thoughts yet refer to two different things 17 for instance when people think of cats the referent of their thoughts would be the cats that are found on earth however people s twins on twin earth though possessing the same thoughts would instead be referring not to earth s cats but to twin earth s cats bearing this in mind he writes that a pure brain in a vat i e one that has never existed outside of the simulation could not even truthfully say that it was a brain in a vat this is because the biv when it says brain and vat can only refer to objects within the simulation not to things outside the simulation it does not have a relationship with putnam refers to this relationship as a causal connection which is sometimes referred to as a causal constraint 18 2 therefore what it says is demonstrably false alternatively if the speaker is not actually a biv then the statement is also false he concludes then that the statement i m a biv is necessarily false and self refuting 17 this argument has been explored at length in philosophical literature since its publication a potential loophole in putnam s reference theory is that a brain on earth that is kidnapped placed into a vat and subjected to a simulation could still refer to brains and vats which are real in the sense of putnam and thus correctly say it is a brain in a vat according to putnamian reference theory 19 however the notion that the pure biv is incorrect and the reference theory underpinning it remains influential in the philosophy of mind language and metaphysics 20 21 anthony l brueckner has formulated an extension of putnam s argument which rules out this loophole by employing a disquotational principle it will be discussed in the following two sections reconstructions of putnam s argument edit an issue that has arisen with putnam s argument is that his premises only imply the metalinguistic statement my utterances of i am a biv are false but a skeptic may demand the object language statement i am a biv to be proven 22 23 to combat this issue various philosophers have reconstructed putnam s argument some like anthony l brueckner and crispin wright have taken approaches that utilize disquotational principles 22 18 others like ted a warfield have taken approaches that focus on the concepts of self knowledge and priori 23 the disjunctive argument edit one of the earliest but influential reconstructions of putnam s transcendental argument was suggested by anthony l brueckner brueckner s reconstruction is as follows 1 either i am a biv speaking vat english or i am a non biv speaking english 2 if i am a biv speaking vat english then my utterances of i am a biv are true if i have sense impressions as of being a biv 3 if i am a biv speaking vat english then i do not have sense impressions as of being a biv 4 if i am a biv speaking vat english then my utterances of i am a biv are false 2 3 5 if i am a non biv speaking english then my utterances of i am a biv are true if i am a biv 6 if i am a non biv speaking english then my utterances of i am a biv are false 5 7 my utterances of i am a biv are false 1 4 6 22 though these premises further define putnam s argument they do not so far prove i am not a biv because although the premises imply the metalinguistic statement my utterances i am a biv are false they do not yet imply the object language statement i am not a biv to achieve the putnamian conclusion brueckner strengthens his argument by employing the disquotational principle my utterances of i am not a biv are true if i am not a biv this statement is justified since the metalanguage that contains the tokens for the disquotational principle also contains the object language tokens to which the utterances i am not a biv belong 22 a poster for the film the brain that wouldn t die 1962 in fiction edit main article isolated brain in fiction agents of s h i e l d season 4 alita battle angel
