Document Summary
Objection to churchland"s materialism: em is incoherent because meaning requires mental states (eg. belief, intention to communicate, knowledge of language. Response: if em is true, meaningfulness has a difference source. This is not a real response: he doesn"t explain what the different source is. Understanding meaning: you make the symbol stand for something else through a mental process- you can"t describe this purely as a brain-state because then you"re missing the mind. Alan turing: if a computer can have a conversation that is indistinguishable from a human conversation, it is intelligent- this is the test. Problems: if you"re online and chatting with a computer, you probably won"t know, this one is outdated. John searle: chinese room argument against strong artificial intelligence. Images he"s in a room where people hand in symbols and he has to hand back certain symbols, according to the rule book. So he can have a conversation with a chinese person without actually understanding chinese.
