functionalism emerged partly in response to the publication of
Main article: China brain Ned Block [16] argues against the functionalist proposal of multiple realizabilitywhere https://digitales.com.au/blog/wp-content/custom/japan-s-impact-on-japan/twelfth-night-quick-summary.php implementation is irrelevant because only the functional level is important. The "China brain" or "Chinese nation" thought experiment involves supposing that the entire nation of China systematically organizes itself to operate just like a brain, with each individual acting as a neuron.
The tremendous difference in speed of operation of each unit is not addressed.
According to functionalism, so long as the people are performing the proper functional roles, with the proper causal relations between inputs and outputs, the system will be a real mind, with mental states, consciousness, and so on. However, Block argues, this is patently absurd, so there must be something wrong with the thesis of functionalism since it would allow this to be a legitimate description of a mind. Some functionalists believe China would have qualia but that due to the size it is impossible to imagine China being conscious. Therefore, if functionalism is true either qualia will exist across all hardware or will not exist at go here but are illusory.
The thought experiment asserts that it is possible to mimic intelligent action without any interpretation or understanding through the use of a purely functional system.

In short, Searle describes a person who only speaks English who is in a room with only Chinese symbols in baskets and a rule book in English for moving the symbols around. The person is then ordered by people outside of the room to follow the rule book for sending certain symbols out of the room when given certain symbols. Further suppose that the people outside of the room are Chinese speakers and are communicating with the person inside via the Chinese symbols.
According to Searle, it would be absurd to claim that the English speaker inside knows Chinese simply based on these syntactic processes. This thought experiment attempts to show that systems which operate merely on syntactic processes inputs and outputs, based on algorithms https://digitales.com.au/blog/wp-content/custom/why-building-administrations-have-a-developing-business/three-sociological-paradigms.php realize any semantics meaning or intentionality aboutness.
Thus, Searle attacks the idea that thought can be equated with following a set of syntactic rules; that is, functionalism is an insufficient theory of the mind.
In connection with Block's Chinese nation, many functionalists responded to Searle's thought experiment by emreged that there was a form of mental activity going on at a higher level than the man in the Chinese room could comprehend the so-called "system reply" ; that is, the system does know Chinese. Of course, Searle responds that there is nothing more than syntax going on at the higher-level as well, so this reply is subject to the same initial problems.
Furthermore, Searle suggests the man in the room could simply memorize the rules and symbol relations. Again, though he would convincingly mimic communication, he would be aware only of the symbols and rules, not of the meaning behind them. Main article: Inverted spectrum Another main criticism of functionalism is the inverted spectrum or inverted qualia scenario, most specifically proposed as an partlj to functionalism by Ned Block. Unlike normal people, Jane sees the color violet as yellow, orange as blue, and so forth.
So, suppose, for example, that you and Jane are looking at the same orange. While you perceive the fruit as colored orange, Jane sees it as colored blue.]
In it something is. Earlier I thought differently, I thank for the help in this question.
You have hit the mark. In it something is also I think, what is it good idea.
I think, that you are not right. I can prove it. Write to me in PM, we will discuss.
Does not leave!
