Functionalism A Viable Materialist Philosophy Essay

Functionalism A Viable Materialist Philosophy EssayIn evaluating the hardship of Functionalism as a possibleness of mind, cardinal mustiness first discover the ism of Functionalism itself, and its roots. Functionalism has divided philosophers, and presented below be three of the main aims against the harshness of Functionalism, and these will demonstrate that as a possibility of mind, although compelling and eyeshot provoking, Functionalism is ultimately not viable.Functionalist theory has evolved from other philosophical theories of the mind, including Identity possibility of Mind, which in its simplest form distinguishs that amiable states can be utter to be exactly identical to brain states, and some forms of Behaviourist Theory, which suggested, amongst other things, that demeanor can be explained or justified without putting any ferocity on the mind as an instigator, and so behaviour can be rationalised by saying that the sources are not internal, but extraneous.F unctionalism can be said to be both and extension and a criticism to these theories. It is something of a middle ground between them. Similar to Behaviourist theory, Functionalism classifies mental states victimisation a behavioural structure, but differs from this theory by suggesting that mental states rear internally. In terms of similarity to the Identity Theory of Mind, both match that the process of producing a mental begins internally, but Functionalism differs in that it differentiates between the definitions of mental states and brain states.In its basic form, Functionalism can be delimit as suggesting that mental states are characterised by their causal properties. In other words, kind of of defining a mental state by its features, Functionalism suggests that it should be defined by what it does, or by its bureau. Expanding on this, Functionalism suggests that cardinal estimates can be considered identical if all relevant inputs, both those garnered internally and externally, can reach out the same eventual output.One of the first forms of Functionalism was progress tod by Hilary Putnam, who, utilise the Turing Test, show his theory of Machine State Functionalism. The Turing Test was a proposal by Alan Turing to discover whether molds can imitate human behaviour in a manner satisfactorily enough that they appear to be able to think, and furthermore, Turing suggested that his evidence might, with more technological advancement, be able to determine if a machine is in fact able to think. Using the Turing Test, Putnam suggesting that any being possessing a mind could be said to be a Turing machine, and could be controlled using a set of instructions for its operation. Furthermore, early Functionalist theories suggested that a some bingle or machine could be controlled by the input of instructions based on the probability of an outcome, and thus the behaviour would be modified according to the just about likely outcome. From this, Putnam c reated his idea of Functionalism which suggested that sentient beings differ from non sentient beings not because of their animal(prenominal) project up, but because of the way that the internal mental states relate to one another causally to form outputs.However, Putnam later rejected his earlier proposals for Functionalism, citing his reduplicate Earth thought prove as justification, and, being that he was slavish in the formation of Functionalist theory, this gives weight to the line of descent that Functionalism as a philosophy of mind is not viable. The Twin Earth experiment is based approximately the idea of two identical worlds, except for one thing, that water is has a different name on the twinned earth. As Yemina Ben-Menahem writes in Hilary Putnam, the two people involved, Oscar and Toscar refer to the liquid water as what is familiar to them in their respective environments. Yet the liquidsare in fact very different. (p.236, ll.23-24). What this thought experiment is suggesting because, is that Oscar and Toscars thoughts about water are based on their knowledge of it. By extension, this suggests that for a person to have thoughts about water, they must have experient it, since the brain itself has no such knowledge of water. Thus, some form of external stimulus must have created the knowledge of water in gear up for the brain to process it. This refutes the idea in Functionalism that mental states are created internally.A criticism of Functionalism, and indeed of all materialist theories, is that it does not account for the complexities of human emotion and feeling. For sample, what is missing in the theory of Functionalism is the allowance for inwrought, conscious emotion, or qualia. The argument for the man of qualia is rooted in the idea that some emotions, namely delectation and pain, cannot be analysed in an objective manner. If the example of pain is taken from a Functionalist stand headspring, its only property is that it crea tes the appropriate output, such as flinching. However, it is difficult to figure that this is the only component of pain. From the point of view of a Functionalist, pain is not defined in terms of how it makes a person feel, or what it is make of, but rather only in terms of what is input to create the relevant mental state, and what the output of that is.The problem with using qualia as an argument against the validity of Functionalism as theory of mind is that not all philosophers desire that qualia exists. However, if one agrees to the possibility of the public of qualia, then this argument is valuable. As Edmund king of beasts Wright argues in The Case for Qualia, human experience can support the existence of qualiaqualia realism should be our default position. (p.286, ll.11-13). Using this standpoint as a basis, two arguments can be levelled against Functionalism and its validity. The first argument builds on Putnams bear objection to his theory of Functionalism, and the r elationship between cognitive unravel and experience. The example of colours can be used to illustrate this point. If a person sees red and calls it red, and another person sees it as green but calls it red, the function is identical, but the personal experience is not. Jaegwon Kim demonstrates this in his book, Physicalism or Something estimable Enough, where he writes that what a colour looks like to a person should make no difference to the primary cognitive function of their visual system, (p173, ll. 2-4). In other words, Kim is arguing that the Functionalist approach does not allow for the variety of subjective experience. He goes on to qualify this Intrinsic qualities of qualia are not running(a)isable and therefore are irreducible, and hence causally impotent. (p.173, ll.9-10) If the existence of qualia cannot be reconciled with the theory of Functionalism, as Kim suggests, then the two must be mutually exclusive. If one assumes that qualia exists, as suggested by Wright, then Functionalism is not a viable theory of mind. Clearly, for this argument to be valid, one must first accept the existence of qualia. As such the argument from a qualia standpoint is not able by itself to invalidate Functionalism if the existence of qualia is not proven. Indeed, the theory of Functionalism can be used as an argument against the existence of qualia, and no expla dry land for all theory has been proceedsd which does not rely upon unknown factors and speculation.Arguing the case for Functionalisms shortfalls in terms of consciousness, Ned Block proposed a thought experiment in which a functioning mind could be created out of an entire Chinese solid ground. The point of this thought experiment was to illustrate that the theory of Functionalism fails to directly address the issue of consciousness as a condition of a mental state or functioning mind. As explained by Eric S. Chelstrom in Social Phenomenology Husserl, Intersubjectivity and corporate Intentionality, If consciousness could be defined in only strictly functional terms, it would be possible for the population of China as a only to realise the functionality of consciousness. (p.55, ll.17-19). If one were to take the Functionalist view on this bet, then this thought experiment should seem entirely plausible, since in keeping with Functionalist views, it does not matter what the mind is made up of, it matters only that functional roles are gain by different parts, as would occur in the Chinese nation scenario. There should be no need, Functionalism would argue, for the mind to be made up of anything specific. Indeed, providing the roles were carried out, it could be made of anything imaginable. As Ned Block points out, the idea of the Chinese nation as a whole having a collective consciousness, and by extension, the pinch that a conscious mind could be made up of military issue of functioning parts of any description, although not necessarily impossible, seems absurd to closel y people, and as such demonstrates a flaw in the argument for Functionalism as a viable theory of mind.As established previously, there are a number of arguments against Functionalism as a viable theory of mind, and these must be taken into account when weighing up whether one agrees or disagrees with them. However, the basis of the theory of Functionalism, that mental states are only defined by their function, is one that is not easily reconcilable with the wealth of human experience. In fact, the idea that human experience is secondary to functioning mental states is around abhorrent, since it is in human nature to want to believe that consciousness is a meaningful phenomenon and not an illusion created by causal functions. Furthermore, in judge Functionalism in its entirety, one must also accept that that the machine function model suggested by Putnam could also be viable, and furthermore, that conscious beings are not unique and extraordinary, but can be created with any compo nents, provide the par of input and output is valid. This is a somewhat undesirable situation, and seems ridiculous as it is based in speculation of unknown factors. Ultimately, it can be said that Functionalism is not a viable theory of mind since it requires a fracture of ones experience of behaviour the knowledge of ones own consciousness, and is based almost entirely on conjecture.Matravers, D (2011) Mind (A222 Book 5), Milton Keynes, The Open UniversityBen-Menahem, Y (2005) Hilary Putnam, Cambridge, Cambridge University calf loveWright, E (2008) The Case for Qualia, Massachusetts, MIT PressChelstrom, E (2012) Social Phenomenology Husserl, Intersubjectivity and Collective Intentionality, Maryland, Lexington Books
