| 3140 | If you explain water as H2O, you have reduced water, but not eliminated it [Rey] |
| Full Idea: Reduction is not the same as elimination; if chemists reduce water to H2O, or biologists reduce life to a complex chemical process, they have not shown that they don't exist. | |
| From: Georges Rey (Contemporary Philosophy of Mind [1997], 1.2.1) | |
| A reaction: Depends what you mean by 'elimination'. It is important to be clear whether you are eliminating something from life, or from strict philosophical ontology. Ontologists never mention mountains. |
| 3134 | Human behaviour can show law-like regularity, which eliminativism can't explain [Rey] |
| Full Idea: There is clear evidence against eliminative materialism in the law-like correlations found among millions of answers in standardised school tests, for which it can give no explanation. | |
| From: Georges Rey (Contemporary Philosophy of Mind [1997], Int.3) | |
| A reaction: Not very persuasive. If neural networks got involved in complex competitions with one another, you would expect them to evolve similar tactics. |
| 3200 | Pattern recognition is puzzling for computation, but makes sense for connectionism [Rey] |
| Full Idea: Connectionism is a way of capturing the holism of pattern recognition, as stressed by many critics of computational theories of mind. | |
| From: Georges Rey (Contemporary Philosophy of Mind [1997], 8.8) | |
| A reaction: I am drawn to the idea that arithmetic derives from pattern recognition, and the latter is basic to all minds (a kind of instant unthinking induction), so this seems to me a win for connectionism. |
| 3201 | Connectionism explains well speed of perception and 'graceful degradation' [Rey] |
| Full Idea: Connectionism is better than other AI strategies at capturing the extraordinary swiftness of perception, and of degrading in a 'graceful' way. | |
| From: Georges Rey (Contemporary Philosophy of Mind [1997], 8.8) | |
| A reaction: A good theory had better capture the extraordinary swiftness of perception. Also the swiftness of recognition. Compare seeing a surprising old friend in a crowd, and recognising the person you are looking for. |
| 3202 | Connectionism explains irrationality (such as the Gamblers' Fallacy) quite well [Rey] |
| Full Idea: Connectionism offers promising accounts of irrational behaviour, such as people's bias towards positive instances, and their tendency to fall for the gamblers' fallacy. | |
| From: Georges Rey (Contemporary Philosophy of Mind [1997], 8.8) | |
| A reaction: That is strong support, because the chances of a computational robot having such tendencies is virtually nil, but all humans have the biases referred to (even philosophers). |
| 3199 | Connectionism assigns numbers to nodes and branches, and plots the outcomes [Rey] |
| Full Idea: In connectionism, each node is given an activation level, and each branch a weight, according to possible degree of effect. This results in 'excitatory' and 'inhibitory' connections. | |
| From: Georges Rey (Contemporary Philosophy of Mind [1997], 8.8) | |
| A reaction: Whether such a system could ever be 'conscious' is not the only interesting question. What could such a system do? Could it ever be good at philosophy? |
| 3150 | Can identity explain reason, free will, non-extension, intentionality, subjectivity, experience? [Rey] |
| Full Idea: Eight properties of mind are problems for the identity theory: rationality, free will, spatiality, privacy, intentionality, essential mentality, subjective content, and the explanatory gap. | |
| From: Georges Rey (Contemporary Philosophy of Mind [1997], 2.7) | |
| A reaction: The list could go on: poetry, creativity, love, normativity... Actually, these are problems for every theory. |
| 3129 | Physicalism offers something called "complexity" instead of mental substance [Rey] |
| Full Idea: In physicalism the "ghost in the machine" is merely replaced by the "complexity" in it. | |
| From: Georges Rey (Contemporary Philosophy of Mind [1997], Int.2) | |
| A reaction: This is nonsense. No one thinks that mere complexity generates consciousness. The assumption is that we would begin to understand the mind only if we could somehow map the connections of the brain. |
