| 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) |
| 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) |
| 16695 | Successive entities are in flux, flowing in existence, with different parts at different times [Oresme] |
| Full Idea: For any time, some of a successive entity exists in one of its parts, and a totally different such exists in another part. …It is in continuous flux and transition, ..and flows in existence if it does not have the same existence over a whole time. | |
| From: Nicole Oresme (On 'Physics' [1346], III.6, dist.1), quoted by Robert Pasnau - Metaphysical Themes 1274-1671 18.1 | |
| A reaction: Pasnau says the successive entity is the whole made up of these changing parts, so it sounds very like the temporal stages view of Sider and Hawley. |
| 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) |
| 21515 | Incoherence may be more important for enquiry than coherence [Olsson] |
| Full Idea: While coherence may lack the positive role many have assigned to it, ...incoherence plays an important negative role in our enquiries. | |
| From: Erik J. Olsson (Against Coherence [2005], 10.1) | |
| A reaction: [He cites Peirce as the main source for this idea] We can hardly by deeply impressed by incoherence if we have no sense of coherence. Incoherence is just one of many markers for theory failure. Missing the target, bad concepts... |
| 21514 | Coherence is the capacity to answer objections [Olsson] |
| Full Idea: According to Lehrer, coherence should be understood in terms of the capacity to answer objections. | |
| From: Erik J. Olsson (Against Coherence [2005], 9) | |
| A reaction: [Keith Lehrer 1990] We can connect this with the Greek requirement of being able to give an account [logos], which is the hallmark of understanding. I take coherence to be the best method of achieving understanding. Any understanding meets Lehrer's test. |
| 21496 | Mere agreement of testimonies is not enough to make truth very likely [Olsson] |
| Full Idea: Far from guaranteeing a high likelihood of truth by itself, testimonial agreement can apparently do so only if the circumstances are favourable as regards independence, prior probability, and individual credibility. | |
| From: Erik J. Olsson (Against Coherence [2005], 1) | |
| A reaction: This is Olson's main thesis. His targets are C.I.Lewis and Bonjour, who hoped that a mere consensus of evidence would increase verisimilitude. I don't see a problem for coherence in general, since his favourable circumstances are part of it. |
| 21499 | Coherence is only needed if the information sources are not fully reliable [Olsson] |
| Full Idea: An enquirer who is fortunate enough to have at his or her disposal fully reliable information sources has no use for coherence, the need for which arises only in the context of less than fully reliable informations sources. | |
| From: Erik J. Olsson (Against Coherence [2005], 2.6.2) | |
| A reaction: I take this to be entirely false. How do you assess reliability? 'I've seen it with my own eyes'. Why trust your eyes? In what visibility conditions do you begin to doubt your eyes? Why do rational people mistrust their intuitions? |
| 21502 | A purely coherent theory cannot be true of the world without some contact with the world [Olsson] |
| Full Idea: The Input Objection says a pure coherence theory would seem to allow that a system of beliefs be justified in spite of being utterly out of contact with the world it purports to describe, so long as it is, to a sufficient extent, coherent. | |
| From: Erik J. Olsson (Against Coherence [2005], 4.1) | |
| A reaction: Olson seems impressed by this objection, but I don't see how a system could be coherently about the world if it had no known contact with the world. Olson seems to ignore meta-coherence, which evaluates the status of the system being studied. |
| 21512 | Extending a system makes it less probable, so extending coherence can't make it more probable [Olsson] |
| Full Idea: Any non-trivial extension of a belief system is less probable than the original system, but there are extensions that are more coherent than the original system. Hence more coherence does not imply a higher probability. | |
| From: Erik J. Olsson (Against Coherence [2005], 6.4) | |
| A reaction: [Olson cites Klein and Warfield 1994; compressed] The example rightly says the extension could have high internal coherence, but not whether the extension is coherent with the system being extended. |
| 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. |
| 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) |
