29 ideas
| 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) |
| 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. |
| 6479 | Noninterference requires justification as much as interference does [Nagel] |
| Full Idea: Noninterference requires justification as much as interference does. | |
| From: Thomas Nagel (Equality and Partiality [1991], Ch.10) | |
| A reaction: I'm not convinced by this, as a simple rule. If I spend my whole life doing just the minimum for my own survival, I don't see why I should have to justify that, and I don't see a state is obliged to justify it either. |
| 6450 | Morality must be motivating, and not because of pre-moral motives [Nagel] |
| Full Idea: My own view is that moral justification must be capable of motivating, but not in virtue of reliance on pre-moral motives. | |
| From: Thomas Nagel (Equality and Partiality [1991], Ch.5) | |
| A reaction: This may well be the core and essence of Kantian moral theory. I'm inclined to think of it as 'Kant's dream', which is of ultra-rational beings who are driven by pure rationality as a motivator. People who fit this bill tend to be academics. |
| 6447 | Game theory misses out the motivation arising from the impersonal standpoint [Nagel] |
| Full Idea: I do not favour the route taken by Hobbes's modern descendants, using game theory, since I believe the impersonal standpoint makes an essential contribution to individual motivation which must be addressed by any ethically acceptable theory. | |
| From: Thomas Nagel (Equality and Partiality [1991], Ch.4) | |
| A reaction: The assumption of self-seeking at the core of game theory seems very bizarre, and leads to moral approval of free riders. Nagel offers the best response, which is the Kantian impersonal view. Nagel may be optimistic about motivation, though. |
| 23405 | Rituals escape natural chaos, and benefit everyone, by reshaping our motivations [Xunzi (Xun Kuang), by Norden] |
| Full Idea: For Xunzi, everyone is better off with rituals …because they allow us to escape the chaotic state of nature. They do not merely set rules for entitlement, though. They are effective because they reshape human motivation. | |
| From: report of Xunzi (Xun Kuang) (The Xunzi [c.250 BCE]) by Bryan van Norden - Intro to Classical Chinese Philosophy 10.2 | |
| A reaction: Rituals are a basic part of Confucianist thinking, and may be puzzling to outsiders. At there worst rituals are brain-washing, but teaching children good manners is a sort of ritual, meant to channel feelings in a healthy direction |
| 23406 | Rituals don't arise from human nature; they are the deliberate creations of a sage [Xunzi (Xun Kuang)] |
| Full Idea: Rituals and standards of righteousness and proper models and measures are produced from the deliberate efforts of the sage; they are not produced from people's nature. | |
| From: Xunzi (Xun Kuang) (The Xunzi [c.250 BCE], 23), quoted by Bryan van Norden - Intro to Classical Chinese Philosophy 10.III | |
| A reaction: This is not to say that the sage is not in tune with nature. Human nature is often seen as a sprouting seed, which needs careful husbandry to bring out its best. |
| 6446 | In ethics we abstract from our identity, but not from our humanity [Nagel] |
| Full Idea: In pursuit of the kind of objectivity needed in the physical sciences, we abstract even from our humanity; but nothing further than abstraction from our identity (that is, who we are) enters into ethical theory. | |
| From: Thomas Nagel (Equality and Partiality [1991], Ch.2) | |
| A reaction: The 'brief' summary of this boils down to a nice and interesting slogan. It epitomises the modern Kantian approach to ethics. But compare Idea 4122, from Bernard Williams. |
| 6477 | I can only universalise a maxim if everyone else could also universalise it [Nagel] |
| Full Idea: It is implicit in the categorical imperative that I can will that everyone should adopt as a maxim only what everyone else can also will that everyone should adopt as a maxim. | |
| From: Thomas Nagel (Equality and Partiality [1991], Ch.5) | |
| A reaction: This is a nice move, because it shifts the theory away from a highly individualistic Cartesian view of morality towards the idea that morality is a community activity. |
| 6448 | A legitimate system is one accepted as both impartial and reasonably partial [Nagel] |
| Full Idea: A legitimate system is one which reconciles the two universal principles of impartiality and reasonable partiality so that no one can object that his interests are not being accorded sufficient weight or that the demands on him are excessive. | |
| From: Thomas Nagel (Equality and Partiality [1991], Ch.4) | |
| A reaction: This seems an appealing principle, and a nice attempt at stating the core of Kantian liberalism. It is obviously influenced by Scanlon's contractualist view, in the idea that 'no one can object', because everyone sees the justification. |
| 6478 | Democracy is opposed to equality, if the poor are not a majority [Nagel] |
| Full Idea: As things are, democracy is the enemy of comprehensive equality, once the poor cease to be a majority. | |
| From: Thomas Nagel (Equality and Partiality [1991], Ch.9) | |
| A reaction: This is obvious once you think about it, but it is well worth saying, because it is tempting to think that we live in an 'equal' society, merely because we are equal in things such as voting rights and equality before the law. |
| 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) |
