2575 | Functionalism is behaviourism, but with mental states as intermediaries [Block] |
Full Idea: Functionalism is a new incarnation of behaviourism, replacing sensory inputs with sensory inputs plus mental states, and replacing dispositions to act with dispositions plus certain mental states. | |
From: Ned Block (Troubles with Functionalism [1978], p. 69) | |
A reaction: I think of functionalism as behaviourism which extends inside the 'black box' between stimulus and response. It proposes internal stimuli and responses. Consequently functionalism inherits some behaviourist problems. |
2576 | In functionalism, desires are internal states with causal relations [Block] |
Full Idea: According to functionalism, a system might have the behaviouristic input-output relations, yet not desire something, as this requires internal states with certain causal relations. | |
From: Ned Block (Troubles with Functionalism [1978], p. 69) | |
A reaction: Such a system might be Putnam's 'superactor', who only behaves as if he desires something. Of course, the internal states might need more than just 'causal relations'. |
2583 | You might invert colours, but you can't invert beliefs [Block] |
Full Idea: It is hard to see how to make sense of the analog of color spectrum inversion with respect to non-qualitative states such a beliefs (where they are functionally equivalent but have different beliefs). | |
From: Ned Block (Troubles with Functionalism [1978], p. 81) | |
A reaction: I would suggest that beliefs can be 'inverted', because there are all sorts of ways to implement a belief, but colour can't be inverted, because that depends on a particular brain state. It makes good sense to me... |
2578 | Could a creature without a brain be in the right functional state for pain? [Block] |
Full Idea: If pain is a functional state, it cannot be a brain state, because creatures without brains could realise the same Turing machine as creatures with brains. | |
From: Ned Block (Troubles with Functionalism [1978], p. 70) | |
A reaction: This strikes me as being a poorly grounded claim. There may be some hypothetical world where brainless creatures implement all our functions, but from here brains look the only plausible option. |
2585 | Not just any old functional network will have mental states [Block] |
Full Idea: If there are any fixed points in the mind-body problem, one of them is that the economy of Bolivia could not have mental states, no matter how it is distorted. | |
From: Ned Block (Troubles with Functionalism [1978], p. 86) | |
A reaction: It is hard to disagree with this, but then it can hardly be a serious suggestion that anyone could see how to reconfigure an economy so that it mapped the functional state of the human brain. This is not a crucial problem. |
2586 | In functionalism, what are the special inputs and outputs of conscious creatures? [Block] |
Full Idea: In functionalism, it is very hard to see how there could be a single physical characterization of the inputs and outputs of all and only creatures with mentality. | |
From: Ned Block (Troubles with Functionalism [1978], p. 87) | |
A reaction: It would be theoretically possible if the only way to achieve mentality was to have a particular pattern of inputs and outputs. I don't think, though, that 'mentality' is an all-or-nothing concept. |
