13966 | Analytic philosophy loved the necessary a priori analytic, linguistic modality, and rigour [Soames] |
Full Idea: The golden age of analytic philosophy (mid 20th c) was when necessary, a priori and analytic were one, all possibility was linguistic possibility, and the linguistic turn gave philosophy a respectable subject matter (language), and precision and rigour. | |
From: Scott Soames (Significance of the Kripkean Nec A Posteriori [2006], p.166) | |
A reaction: Gently sarcastic, because Soames is part of the team who have put a bomb under this view, and quite right too. Personally I think the biggest enemy in all of this lot is not 'language' but 'rigour'. A will-o-the-wisp philosophers dream of. |
2956 | There is nothing so obvious that a philosopher cannot be found to deny it [Lockwood] |
Full Idea: There is nothing so obvious that a philosopher cannot be found to deny it. | |
From: Michael Lockwood (Mind, Brain and the Quantum [1989], p.73) | |
A reaction: [Idea of Varro] Just as unreliable witnesses are the bane of a murder enquiry, so bad philosophers throw a cloud of obscurity roundphilosophy. If 9999 people thought 2+2=4, but there is always one who thinks something different. |
2963 | There may only be necessary and sufficient conditions (and counterfactuals) because we intervene in the world [Lockwood] |
Full Idea: Perhaps notions of necessary and sufficient conditions, and counterfactual considerations, are in some way grounded in awareness of ourselves as active interveners and experimenters in the world, not passive spectators. | |
From: Michael Lockwood (Mind, Brain and the Quantum [1989], p.155) |
13974 | If philosophy is analysis of meaning, available to all competent speakers, what's left for philosophers? [Soames] |
Full Idea: If all of philosophy is the analysis of meaning, and meaning is fundamentally transparent to competent speakers, there is little room for philosophically significant explanations and theories, since they will be necessary or a priori, or both. | |
From: Scott Soames (Significance of the Kripkean Nec A Posteriori [2006], p.186) | |
A reaction: He cites the later Wittgenstein as having fallen into this trap. I suppose any area of life can have its specialists, but I take Shakespeare to be a greater master of English than any philosopher I have ever read. |
2958 | No one has ever succeeded in producing an acceptable non-trivial analysis of anything [Lockwood] |
Full Idea: I cannot think of a single philosophically interesting concept that has been successfully and nontrivially analysed to most people's satisfaction. | |
From: Michael Lockwood (Mind, Brain and the Quantum [1989], p.121) |
2959 | If something is described in two different ways, is that two facts, or one fact presented in two ways? [Lockwood] |
Full Idea: Do the statements 'Sir Percy Blakeney is in Paris' and 'The Scarlet Pimpernel is in Paris' express different facts, or the same fact under different modes of presentation? | |
From: Michael Lockwood (Mind, Brain and the Quantum [1989], p.129) |
2969 | How does a direct realist distinguish a building from Buckingham Palace? [Lockwood] |
Full Idea: It is one thing to see a building, and another to see it as a building, and yet another to see it as Buckingham Palace. How does the commonsense realist think that this is accomplished? | |
From: Michael Lockwood (Mind, Brain and the Quantum [1989], p.302) |
13969 | Kripkean essential properties and relations are necessary, in all genuinely possible worlds [Soames] |
Full Idea: By (Kripkean) 'essential' properties and relations I mean simply properties and relations that hold necessarily of objects (in all genuinely possible world-states in which the objects exist). | |
From: Scott Soames (Significance of the Kripkean Nec A Posteriori [2006], p.168 n5) | |
A reaction: This is the standard modern view of essences which I find so unsatisfactory. Kit Fine has helped to take us back to the proper Aristotelian view, where 'necessary' and 'essential' actually have different meanings. Note the inclusion of relations. |
13973 | A key achievement of Kripke is showing that important modalities are not linguistic in source [Soames] |
Full Idea: None of Kripke's many achievements is more important than his breaking the spell of the linguistic as the source of philosophically important modalities. | |
From: Scott Soames (Significance of the Kripkean Nec A Posteriori [2006], p.186) | |
A reaction: Put like that, Kripke may have had the single most important thought of modern times. I take good philosophy to be exactly the same as good scientific theorising, in that it all arises out of the nature of reality (and I include logic in that). |
13968 | Kripkean possible worlds are abstract maximal states in which the real world could have been [Soames] |
Full Idea: For the Kripkean possible states of the world are not alternate concrete universes, but abstract objects. Metaphysically possible world-states are maximally complete ways the real concrete universe could have been. | |
From: Scott Soames (Significance of the Kripkean Nec A Posteriori [2006], p.167) | |
A reaction: This is probably clearer about the Kripkean view than Kripke ever is, but then that is part of Soames's mission. It sounds like the right way to conceive possible worlds. At least there is some commitment there, rather than instrumentalism about them. |
2970 | Dogs seem to have beliefs, and beliefs require concepts [Lockwood] |
Full Idea: Dogs surely have beliefs, and beliefs call for some concepts or other. | |
From: Michael Lockwood (Mind, Brain and the Quantum [1989], p.312) |
2961 | Empiricism is a theory of meaning as well as of knowledge [Lockwood] |
Full Idea: Empiricism is not just a theory of knowledge; it is also a theory meaning. | |
From: Michael Lockwood (Mind, Brain and the Quantum [1989], p.149) |
2960 | Commonsense realism must account for the similarity of genuine perceptions and known illusions [Lockwood] |
Full Idea: Commonsense realism has to account for the subjective similarity of the genuine perception of a green surface and the experience of, say, an after-image. | |
From: Michael Lockwood (Mind, Brain and the Quantum [1989], p.142) |
2952 | A 1988 estimate gave the brain 3 x 10-to-the-14 synaptic junctions [Lockwood] |
Full Idea: It is estimated by Gierer (1988) that the human cerebral cortex alone contains about 300,000,000,000,000 synaptic junctions. | |
From: Michael Lockwood (Mind, Brain and the Quantum [1989], p.46) | |
A reaction: As we grasp the vastness of this number, and the fact that the junctions are all active, the idea that a brain does something astonishing is not quite so surprising. |
2964 | How come unconscious states also cause behaviour? [Lockwood] |
Full Idea: Anyone who thinks phenomenal qualities are inseparable from our awareness of them, must think subconscious mental states are totally devoid of phenomenal qualities! So how can these states cause behaviour in the way conscious states do? | |
From: Michael Lockwood (Mind, Brain and the Quantum [1989], p.166) | |
A reaction: I agree with this thought, though it is beautifully unprovable. We would need to respond to a red traffic light, without having consciously registered its presence. It is is just increasingly clear that we register information pre-consciously. |
2951 | Could there be unconscious beliefs and desires? [Lockwood] |
Full Idea: I cannot make intuitive sense of there existing a being who possessed genuine beliefs and desires, but who, or which, lacked the capacity for consciousness altogether. | |
From: Michael Lockwood (Mind, Brain and the Quantum [1989], p.44) | |
A reaction: This is part of the recent move (which strikes me as correct) to see qualia and intentionality as inseparable. We might well, though, need to adopt the 'intentional stance' to a sophisticated robot. But am I aware of all of my beliefs? |
2953 | Fish may operate by blindsight [Lockwood] |
Full Idea: If one asks 'what does the world look like to a fish?' the answer may be 'it doesn't look like anything; fish find their way about by blindsight.' | |
From: Michael Lockwood (Mind, Brain and the Quantum [1989], p.56) | |
A reaction: This strikes me as a real possibility, not just a wild speculation. It seems pretty obvious to me that I operate by blindsight in many aspects of my behaviour. Piano-playing would be impossible if all qualia had to be processed. |
2967 | We might even learn some fundamental physics from introspection [Lockwood] |
Full Idea: I am suggesting that introspective psychology might have a contribution to make to fundamental physics. | |
From: Michael Lockwood (Mind, Brain and the Quantum [1989], p.176) | |
A reaction: I'm a fan of introspection, as a source of genuine information. |
2966 | Can phenomenal qualities exist unsensed? [Lockwood] |
Full Idea: Halting the slide into panpsychism is the major advantage of holding that phenomenal qualities can exist unsensed. | |
From: Michael Lockwood (Mind, Brain and the Quantum [1989], p.170) | |
A reaction: Presumably unsensed phenomenal qualities would explain the discovery that we seem to make decisions before we are conscious of what we intend to do. That result certainly implied that consciousness had no real function. |
2955 | If mental events occur in time, then relativity says they are in space [Lockwood] |
Full Idea: If we assume that mental events are located in time, then it follows immediately, given special relativity, that they are also in space. | |
From: Michael Lockwood (Mind, Brain and the Quantum [1989], p.73) | |
A reaction: A powerful point. Of course, there might (you never know) be something which exists in time but not space (and thoughts clearly exist in time), but (as in Hume's argument against miracles), dualism will overthrow your other basic beliefs about nature. |
2950 | Only logical positivists ever believed behaviourism [Lockwood] |
Full Idea: Philosophical behaviourism is an absurd theory. Practically the only philosophers who ever held it, at any rate in its crude form, were certain logical positivists. | |
From: Michael Lockwood (Mind, Brain and the Quantum [1989], p.25) | |
A reaction: I presume Lockwood's target here is eliminativist behaviourism, as opposed to methodological behaviourism (which is a reasonable practice to adopt), and 'black box' behaviourism (which has been superseded by functionalism). |
2954 | Identity theory likes the identity of lightning and electrical discharges [Lockwood] |
Full Idea: A favourite example of identity theorists is the identification of flashes of lightning with electrical discharges. | |
From: Michael Lockwood (Mind, Brain and the Quantum [1989], p.71) | |
A reaction: Personally I prefer the analogy of the mind being like a waterfall - a non-mysterious physical process which has dramatic properties of its own. If minds must keep busy in order to be minds, they must be processes. |
2971 | Perhaps logical positivism showed that there is no dividing line between science and metaphysics [Lockwood] |
Full Idea: If the logical positivists established anything it is that there is no way of demarcating science from metaphysics. | |
From: Michael Lockwood (Mind, Brain and the Quantum [1989], p.313) | |
A reaction: So many problems arise for philosophers because of the passion for 'demarcating' things. Close study, experiments, statistics and measurements occur in every walk of life. |
13972 | Two-dimensionalism reinstates descriptivism, and reconnects necessity and apriority to analyticity [Soames] |
Full Idea: Two-dimensionalism is a fundamentally anti-Kripkean attempt to reinstate descriptivism about names and natural kind terms, to reconnect necessity and apriority to analyticity, and return philosophy to analytic paradigms of its golden age. | |
From: Scott Soames (Significance of the Kripkean Nec A Posteriori [2006], p.183) | |
A reaction: I presume this is right, and it is so frustrating that you need Soames to spell it out, when Chalmers is much more low-key. Philosophers hate telling you what their real game is. Why is that? |
7861 | Libet says the processes initiated in the cortex can still be consciously changed [Libet, by Papineau] |
Full Idea: Libet himself points out that the conscious decisions still have the power to 'endorse' or 'cancel', so to speak, the processes initiated by the earlier cortical activity: no action will result if the action's execution is consciously countermanded. | |
From: report of Benjamin Libet (Unconscious Cerebral Initiative [1985]) by David Papineau - Thinking about Consciousness 1.4 | |
A reaction: This is why Libet's findings do not imply 'epiphenomenalism'. It seems that part of a decisive action is non-conscious, undermining the all-or-nothing view of consciousness. Searle tries to smuggle in free will at this point (Idea 3817). |
6660 | Libet found conscious choice 0.2 secs before movement, well after unconscious 'readiness potential' [Libet, by Lowe] |
Full Idea: Libet found that a subject's conscious choice to move was about a fifth of a second before movement, and thus later than the onset of the brain's so-called 'readiness potential', which seems to imply that unconscious processes initiates action. | |
From: report of Benjamin Libet (Unconscious Cerebral Initiative [1985]) by E.J. Lowe - Introduction to the Philosophy of Mind Ch.9 | |
A reaction: Of great interest to philosophers! It seems to make conscious choices epiphenomenal. The key move, I think, is to give up the idea of consciousness as being all-or-nothing. My actions are still initiated by 'me', but 'me' shades off into unconsciousness. |
2962 | Maybe causation is a form of rational explanation, not an observation or a state of mind [Lockwood] |
Full Idea: It is tempting to see the concept of causation as a product of reason rather than of perception or introspection; something that reason brings to bear on the data of sense, by way of imposing an explanatory order on them. | |
From: Michael Lockwood (Mind, Brain and the Quantum [1989], p.154) |
2949 | We have the confused idea that time is a process of change [Lockwood] |
Full Idea: Somehow we have got it into our heads that time itself is a process of change. | |
From: Michael Lockwood (Mind, Brain and the Quantum [1989], p.12) |
