| 6653 | Syntactical methods of proof need only structure, where semantic methods (truth-tables) need truth [Lowe] |
| Full Idea: Syntactical methods of proof (e.g.'natural deduction') have regard only to the formal structure of premises and conclusions, whereas semantic methods (e.g. truth-tables) consider their possible interpretations as expressing true or false propositions. | |
| From: E.J. Lowe (Introduction to the Philosophy of Mind [2000], Ch. 8) | |
| A reaction: This is highly significant, because the first method of reasoning could be mechanical, whereas the second requires truth, and hence meaning, and hence (presumably) consciousness. Is full rationality possible with 'natural deduction'? |
| 6504 | For physicalists, the only relations are spatial, temporal and causal [Robinson,H] |
| Full Idea: Spatial, temporal and causal relations are the only respectable candidates for relations for a physicalist. | |
| From: Howard Robinson (Perception [1994], V.4) | |
| A reaction: This seems to be true, and is an absolutely crucial principle upon which any respectable physicalist account of the world must be built. It means that physicalists must attempt to explain all mental events in causal terms. |
| 6520 | If reality just has relational properties, what are its substantial ontological features? [Robinson,H] |
| Full Idea: Some thinkers claim the physical world consists just of relational properties - generally of active powers or fields; ..but an ontology of mutual influences is not an ontology at all unless the possessors of the influence have more substantial features. | |
| From: Howard Robinson (Perception [1994], IX.3) | |
| A reaction: I think this idea is one of the keys to wisdom. It is the same problem with functional explanations - you are left asking WHY this thing can have this particular function. Without the buck stopping at essences you are chasing your explanatory tail. |
| 12693 | A body is that which exists in space [Leibniz] |
| Full Idea: A body is defined as that which exists in space. | |
| From: Gottfried Leibniz (Confessio naturae contra atheistas [1669], A6.1.490), quoted by Daniel Garber - Leibniz:Body,Substance,Monad 1 | |
| A reaction: A very early view. Leibniz notes that this tells you nothing about shape and motion. |
| 6618 | A 'substance' is a thing that remains the same when its properties change [Lowe] |
| Full Idea: By 'substance', in the context of the mind, we mean a persisting object or thing which can undergo changes in its properties over time while remaining one and the same thing. | |
| From: E.J. Lowe (Introduction to the Philosophy of Mind [2000], Ch. 2) | |
| A reaction: A neat account of the traditional philosophical notion of a substance. It invites the obvious question of how you know that a thing is the same if all of its properties seem to have changed (as with Descartes' wax). Epistemology discredits ontology. |
| 6635 | Causal theories of belief make all beliefs true, and can't explain belief about the future [Lowe] |
| Full Idea: The causal theory of beliefs seems condemned to treat all beliefs as true, which is absurd, …and we do not want to say that tomorrow's rain 'causes' today's belief that it will rain tomorrow. | |
| From: E.J. Lowe (Introduction to the Philosophy of Mind [2000], Ch. 4) | |
| A reaction: This is aimed at Fodor. A false belief might be caused by reality if one had one's internal wires crossed, and a belief about the future might be caused by events happening now. This theory is not dead. |
| 6619 | Perhaps 'I' no more refers than the 'it' in 'it is raining' [Lowe] |
| Full Idea: Perhaps the 'I' in 'I think' no more serves to pick out a certain object than does the 'it' in 'it is raining'. | |
| From: E.J. Lowe (Introduction to the Philosophy of Mind [2000], Ch. 2) | |
| A reaction: A nice example to remind us that not all English pronouns have genuine reference. You could reply that 'it' does refer, to the weather; or that you can switch to 'you think', but not to 'they/we are raining'. |
| 6485 | When a red object is viewed, the air in between does not become red [Robinson,H] |
| Full Idea: When the form of red passes from an object to the eye, the air in between does not become red. | |
| From: Howard Robinson (Perception [1994], 1.2) | |
| A reaction: This strikes me as a crucial and basic fact which must be faced by any philosopher offering a theory of perception. I would have thought it instantly eliminated any sort of direct or naïve realism. The quale of red is created by my brain. |
| 6643 | 'Ecological' approaches say we don't infer information, but pick it up directly from reality [Lowe] |
| Full Idea: The 'ecological' approach to perception resists the idea that our brains have to construct information about our environment by inference from sensations, because the information is already present in the environment, available to well-tuned senses. | |
| From: E.J. Lowe (Introduction to the Philosophy of Mind [2000], Ch. 6) | |
| A reaction: The psychologist J.J.Gibson is the source of this view. This pushes us towards direct realism, and away from representative theories, which are based too much on problems arising from illusions (which are freak cases). Interesting. |
| 6521 | Representative realists believe that laws of phenomena will apply to the physical world [Robinson,H] |
| Full Idea: One thing which is meant by saying that the phenomenal world represents or resembles the transcendental physical world is that the scientific laws devised to apply to the former, if correct, also apply (at least approximately) to the latter. | |
| From: Howard Robinson (Perception [1994], IX.3) | |
| A reaction: This is not, of course, an argument, or a claim which can be easily substantiated, but it does seem to be a nice statement of a central article of faith for representative realists. The laws of the phenomenal world are the only ones we are going to get. |
| 6509 | Representative realists believe some properties of sense-data are shared by the objects themselves [Robinson,H] |
| Full Idea: A representative realist believes that at least some of the properties that are ostensively demonstrable in virtue of being exemplified in sense-data are of the same kind as some of those exemplified in physical objects. | |
| From: Howard Robinson (Perception [1994], VII.5) | |
| A reaction: It is hard to pin down exactly what is being claimed here. Locke's primary qualities will obviously qualify, but could properties be 'exemplified' in sense-data without them actually being the same as those of the objects? |
| 6522 | Phenomenalism can be theistic (Berkeley), or sceptical (Hume), or analytic (20th century) [Robinson,H] |
| Full Idea: It is useful to identify three kinds of phenomenalism: theistic, sceptical and analytic; the first is represented by Berkeley, the second by Hume, and the third by most twentieth-century phenomenalists. | |
| From: Howard Robinson (Perception [1994], IX.4) | |
| A reaction: In Britain the third group is usually represented by A.J.Ayer. My simple objection to all phenomenalists is that they are intellectual cowards because they won't venture to give an explanation of the phenomena which confront them. |
| 6502 | Can we reduce perception to acquisition of information, which is reduced to causation or disposition? [Robinson,H] |
| Full Idea: Many modern physicalists first analyse perception as no more than the acquisition of beliefs or information through the senses, and then analyse belief and the possession of information in causal or dispositional terms. | |
| From: Howard Robinson (Perception [1994], V.1) | |
| A reaction: (He mentions Armstrong, Dretske and Pitcher). A reduction to dispositions implies behaviourism. This all sounds more like an eliminativist strategy than a reductive one. I would start by saying that perception is only information after interpretation. |
| 6513 | Would someone who recovered their sight recognise felt shapes just by looking? [Robinson,H] |
| Full Idea: Molyneux's Problem is whether someone who was born blind and acquired sight would be able to recognise, on sight, which shapes were which; that is, would they see which shape was the one that felt so-and-so? | |
| From: Howard Robinson (Perception [1994], VIII.7) | |
| A reaction: (Molyneux wrote a letter to John Locke about this). It is a good question, and much discussed in modern times. My estimation is that the person would recognise the shapes. We are partly synaesthetic, and see sharpness as well as feeling it. |
| 6512 | Secondary qualities have one sensory mode, but primary qualities can have more [Robinson,H] |
| Full Idea: Primary qualities and secondary qualities are often distinguished on the grounds that secondaries are restricted to one sensory modality, but primaries can appear in more. | |
| From: Howard Robinson (Perception [1994], VIII.7) | |
| A reaction: This distinction seems to me to be accurate and important. It is not just that the two types are phenomenally different - it is that the best explanation is that the secondaries depend on their one sense, but the primaries are independent. |
| 6497 | We say objects possess no intrinsic secondary qualities because physicists don't need them [Robinson,H] |
| Full Idea: The idea that objects do not possess secondary qualities intrinsically rests on the thought that they do not figure in the physicist's account of the world; ..as they are causally idle, no purpose is served by attributing them to objects. | |
| From: Howard Robinson (Perception [1994], III.1) | |
| A reaction: On the whole I agree with this, but colours (for example) are not causally idle, as they seem to affect the behaviour of insects. They are properties which can only have a causal effect if there is a brain in their vicinity. Physicists ignore brains. |
| 6494 | If objects are not coloured, and neither are sense-contents, we are left saying that nothing is coloured [Robinson,H] |
| Full Idea: If there are good reasons for thinking that physical objects are not literally coloured, and one also refuses to attribute them to sense-contents, then one will have the bizarre theory (which has been recently adopted) that nothing is actually coloured. | |
| From: Howard Robinson (Perception [1994], 1.7) | |
| A reaction: It seems to me that objects are not literally coloured, that the air in between does not become coloured, and that my brain doesn't turn a funny colour, so that only leaves colour as an 'interior' feature of certain brain states. That's how it is. |
| 6499 | Shape can be experienced in different ways, but colour and sound only one way [Robinson,H] |
| Full Idea: Shape can be directly experienced by either touch or sight, which are subjectively different; but colour and sound can be directly experienced only through experiences which are subjectively like sight and hearing. | |
| From: Howard Robinson (Perception [1994], III.1) | |
| A reaction: This seems to be a key argument in support of the distinction between primary and secondary qualities. It seems to me that the distinction may be challenged and questioned, but to deny it completely (as Berkeley and Hume do) is absurd. |
| 6500 | If secondary qualities match senses, would new senses create new qualities? [Robinson,H] |
| Full Idea: As secondary qualities are tailored to match senses, a proliferation of senses would lead to a proliferation of secondary qualities. | |
| From: Howard Robinson (Perception [1994], III.1) | |
| A reaction: One might reply that if we experienced, say, magnetism, we would just be discerning a new fine grained primary quality, not adding something new to the ontological stock of properties in the world. It is a matter of HOW we experience the magnetism. |
| 6638 | One must be able to visually recognise a table, as well as knowing its form [Lowe] |
| Full Idea: A bare knowledge that tables have a particular form will not enable one to recognise a table visually, unless one knows how something with such a form typically appears or looks from a variety of different angles. | |
| From: E.J. Lowe (Introduction to the Philosophy of Mind [2000], Ch. 6) | |
| A reaction: This seems to be a rather significant point, if we are trying to work out how concepts and models operate in the process of perception. Lowe points out that with electrons, we have some knowledge of the form, but no capacity for recognition. |
| 6644 | Computationalists object that the 'ecological' approach can't tell us how we get the information [Lowe] |
| Full Idea: Computational psychologists object to the 'ecological' approach to perception (with its externalist, direct realist picture), because it leaves us entirely in the dark as to how our senses 'pick up' information about the environment. | |
| From: E.J. Lowe (Introduction to the Philosophy of Mind [2000], Ch. 6) | |
| A reaction: I find myself siding with the computationalists, but then I have always favoured the representational view of perception among philosophers. Lowe comments that both approaches neglect actual experience. We construct models, e.g. of London. |
| 6647 | Comparing shapes is proportional in time to the angle of rotation [Lowe] |
| Full Idea: When two objects, one of them rotated, are compared, the length of time it takes the subjects to determine they are of the same shape is roughly proportional to the size of angle of rotation, ...which suggests analogue modes of representation. | |
| From: E.J. Lowe (Introduction to the Philosophy of Mind [2000], Ch. 7) | |
| A reaction: I consider this to be highly significant for our whole understanding of the mind, which I think of as a set of models organised like a database. Think about the weather, phenomenalism, London, the Renaissance, your leg. You play with models. |
| 6484 | Most moderate empiricists adopt Locke's representative theory of perception [Robinson,H] |
| Full Idea: The representative theory of perception is found in Locke, and is adopted by most moderate empiricists. | |
| From: Howard Robinson (Perception [1994], 1.2) | |
| A reaction: This is, I think, my own position. Anything less than fairly robust realism strikes me as being a bit mad (despite Berkeley's endless assertions that he is preaching common sense), and direct realism seems obviously false. |
| 6508 | Sense-data leads to either representative realism or phenomenalism or idealism [Robinson,H] |
| Full Idea: The sense-datum theorist is either a representative realist or a phenomenalist (with which we can classify idealism for present purposes). | |
| From: Howard Robinson (Perception [1994], VII.5) | |
| A reaction: The only alternative to these two positions seems to be some sort of direct realism. I class myself as a representative realist, as this just seems (after a very little thought about colour blindness) to be common sense. I'm open to persuasion. |
| 6480 | Sense-data do not have any intrinsic intentionality [Robinson,H] |
| Full Idea: I understand sense-data as having no intrinsic intentionality; that is, though it may suggest, by habit, things beyond it, in itself it possesses only sensible qualities which do not refer beyond themselves. | |
| From: Howard Robinson (Perception [1994], 1.1) | |
| A reaction: This seems right, as the whole point of proposing sense-data was as something neutral between realism and anti-realism |
| 6482 | For idealists and phenomenalists sense-data are in objects; representative realists say they resemble objects [Robinson,H] |
| Full Idea: For idealists and phenomenalists sense-data are part of physical objects, for objects consist only of actual or actual and possible sense-data; representative realists say they just have an abstract and structural resemblance to objects. | |
| From: Howard Robinson (Perception [1994], 1.1) | |
| A reaction: He puts Berkeley, Hume and Mill in the first group, and Locke in the second. Russell belongs in the second. The very fact that there can be two such different theories about the location of sense-data rather discredits the whole idea. |
| 6505 | Sense-data are rejected because they are a veil between us and reality, leading to scepticism [Robinson,H] |
| Full Idea: Resistance to the sense-datum theory is inspired mainly by the fear that such data constitute a veil of perception which stands between the observer and the external world, threatening scepticism, or even solipsism. | |
| From: Howard Robinson (Perception [1994], VII.1) | |
| A reaction: It is very intellectually dishonest to reject any theory because it leads to scepticism or relativism. This is a common failing among quite good professional philosophers. See Idea 241. |
| 6639 | The 'disjunctive' theory of perception says true perceptions and hallucinations need have nothing in common [Lowe] |
| Full Idea: The 'disjunctive' theory of perception says that we have either veridical perception or else hallucination, but there is no common element in the form of a 'perceptual experience' which would be present in either case and merely caused in different ways. | |
| From: E.J. Lowe (Introduction to the Philosophy of Mind [2000], Ch. 6) | |
| A reaction: McDowell is associated with this view. It seems to be another attempt to get rid of sense-data. It seems odd, though, to say that a hallucination of a dagger has nothing in common at all with experience of real daggers. Why did hallucinations evolve? |
| 6640 | A causal theorist can be a direct realist, if all objects of perception are external [Lowe] |
| Full Idea: A causal theorist can be a 'direct realist' in the sense that he can hold that the only objects of perception are external objects. | |
| From: E.J. Lowe (Introduction to the Philosophy of Mind [2000], Ch. 6) | |
| A reaction: There still seem to be problems with perceiving reflections, or very distant objects (the time-lag problem), or perceiving 'secondary' qualities. |
| 6645 | If blindsight shows we don't need perceptual experiences, the causal theory is wrong [Lowe] |
| Full Idea: If we don't need to have perceptual experiences in order to see things (as 'blindsight' might suggest), the causal theory of perception cannot be correct. | |
| From: E.J. Lowe (Introduction to the Philosophy of Mind [2000], Ch. 6) | |
| A reaction: This is because the causal theory implies a chain of events culminating in experience as the last stage. There is no suggestion, though, that unconscious perception would be non-causal, as it bypasses all the problems about consciousness. |
| 6506 | 'Sense redly' sounds peculiar, but 'senses redly-squarely tablely' sounds far worse [Robinson,H] |
| Full Idea: 'Sense redly' sounds peculiar, but 'senses redly-squarely' or 'red-squarely' or 'senses redly-squarely-tablely' and other variants sound far worse. | |
| From: Howard Robinson (Perception [1994], VII.5) | |
| A reaction: This is a comment on the adverbial theory, which is meant to replace representative theories based on sense-data. The problem is not that it sounds weird; it is that while plain red can be a mode of perception, being a table obviously can't. |
| 6507 | Adverbialism sees the contents of sense-experience as modes, not objects [Robinson,H] |
| Full Idea: The defining claim of adverbialism is that the contents of sense-experience are modes, not objects, of sensory activity. | |
| From: Howard Robinson (Perception [1994], VII.5) | |
| A reaction: This seems quite a good account of simple 'modes' like colour, but not so good when you instantly perceive a house. It never seems wholly satisfactory to sidestep the question of 'what are you perceiving when you perceive red or square?' |
| 6511 | If there are only 'modes' of sensing, then an object can no more be red or square than it can be proud or lazy. [Robinson,H] |
| Full Idea: If only modes of sensing are ostensively available, ..then it is a category mistake to see any resemblance between what is available and properties of bodies; one could as sensibly say that a physical body is proud or lazy as that it is red or square. | |
| From: Howard Robinson (Perception [1994], VII.5) | |
| A reaction: This is an objection to the 'adverbial' theory of perception. It looks to me like a devastating objection, if the theory is meant to cover primary qualities as well as secondary. Red could be a mode of perception, but not square, surely? |
| 6637 | How could one paraphrase very complex sense-data reports adverbially? [Lowe] |
| Full Idea: How could one paraphrase the sense-datum report 'I am aware of a red square sense-datum to the right of a blue round sense-datum' in an adverbial way? 'I am appeared to redly and squarely and roundly and bluely'? | |
| From: E.J. Lowe (Introduction to the Philosophy of Mind [2000], Ch. 5) | |
| A reaction: It is a nice question, but not an instant refutation of the adverbial theory. Vision may be a complex tangle of modes of seeing things, rather than a large collection of sense-data. As I look out of the window, how many sense-data do I experience? |
| 6667 | There are memories of facts, memories of practical skills, and autobiographical memory [Lowe] |
| Full Idea: Memory of facts is quite different from memory of practical skills, and both are quite distinct from what is sometimes called personal or autobiographical memory. | |
| From: E.J. Lowe (Introduction to the Philosophy of Mind [2000], Ch.10) | |
| A reaction: If we accept David Marshall's proposal (Idea 6668), then all of the mind is memory, of many different types, and so the above analysis will be much too simple. |
| 6642 | Psychologists say illusions only occur in unnatural and passive situations [Lowe] |
| Full Idea: Psychologists point out that illusions almost always occur in unnatural environments in which subjects are prevented from exploiting the natural interplay between perception and action. | |
| From: E.J. Lowe (Introduction to the Philosophy of Mind [2000], Ch. 6) | |
| A reaction: It has always struck me that philosophers make a great deal out of illusions, but I don't think I have ever had one. I don't know anyone who has seen a non-existent dagger. |
| 6515 | An explanation presupposes something that is improbable unless it is explained [Robinson,H] |
| Full Idea: Any search for an explanation presupposes that there is something in need of an explanation - that is, something which is improbable unless explained. | |
| From: Howard Robinson (Perception [1994], IX.3) | |
| A reaction: Elementary enough, but it underlines the human perspective of all explanations. I may need an explanation of baseball, where you don't. |
| 6517 | If all possibilities are equal, order seems (a priori) to need an explanation - or does it? [Robinson,H] |
| Full Idea: The fact that order requires an explanation seems to be an a priori principle; ..we assume all possibilities are equally likely, and so no striking regularities should emerge; the sceptic replies that a highly ordered sequence is as likely as any other. | |
| From: Howard Robinson (Perception [1994], IX.3) | |
| A reaction: An independent notion of 'order' is required. If I write down '14356', and then throw 1 4 3 5 6 on a die, the match is the order; instrinsically 14356 is nothing special. If you threw the die a million times, a run of six sixes seems quite likely. |
| 6641 | Externalists say minds depend on environment for their very existence and identity [Lowe] |
| Full Idea: Externalism maintains that our minds 'reach out' into our physical environment, at least in the sense that our states of mind can depend for their very existence and identity upon what things that environment contains. | |
| From: E.J. Lowe (Introduction to the Philosophy of Mind [2000], Ch. 6) | |
| A reaction: A nice statement of the externalist view. Does this mean that a brain in a vat would not have a mind? Does a photograph 'reach out' to its subject-matter? |
| 6617 | The main questions are: is mind distinct from body, and does it have unique properties? [Lowe] |
| Full Idea: Philosophy of mind seems to address the questions of whether the mind is distinct from the body, and whether the mind has properties, such as consciousness, which are unique to it. | |
| From: E.J. Lowe (Introduction to the Philosophy of Mind [2000], Intro) | |
| A reaction: Simple enough, but the modern debate seems to centre on the second question, which is here stated nice and clearly. Of course, wild garlic has a unique smell, but that doesn't quite qualify as a 'unique property'. Are the properties of mind unpredictable? |
| 6626 | 'Phenomenal' consciousness is of qualities; 'apperceptive' consciousness includes beliefs and desires [Lowe] |
| Full Idea: There is 'phenomenal' consciousness, which is what is distinctive of qualitative states of experience, and 'apperceptive' consciousness, which is awareness of all of one's mental states, including beliefs and desires. | |
| From: E.J. Lowe (Introduction to the Philosophy of Mind [2000], Ch. 3) | |
| A reaction: I am not convinced that this distinction is sharp enough to be useful, though I approve of trying to analyse the components of consciousness. Is there 'intentional' consciousness? Desires, and even beliefs, can have qualities. |
| 6481 | If intentional states are intrinsically about other things, what are their own properties? [Robinson,H] |
| Full Idea: Intentional states are mysterious things; if they are intrinsically about other things, what properties, if any, do they possess intrinsically? | |
| From: Howard Robinson (Perception [1994], 1.1) | |
| A reaction: A very nice question, which I suspect to be right at the heart of the tendency towards externalist accounts of the mind. Since you can only talk about the contents of the thoughts, you can't put forward a decent internalist account of what is going on. |
| 6646 | The brain may have two systems for vision, with only the older one intact in blindsight [Lowe] |
| Full Idea: Some physiologists maintain that the human brain is equipped with two different visual systems, an older one and a more recently evolved one, only the first of which is intact in blindsight subjects. | |
| From: E.J. Lowe (Introduction to the Philosophy of Mind [2000], Ch. 6) | |
| A reaction: Ramachandran (on TV) suggested that lizards lack the newer system, and therefore may not actually be conscious. The proposal of two systems seems to make nice sense of an odd phenomenon. We clearly have a non-conscious route to visual information. |
| 6665 | Persons are selves - subjects of experience, with reflexive self-knowledge [Lowe] |
| Full Idea: I suggest that persons are selves - that is, they are subjects of experience which have the capacity to recognised themselves as being individual subjects of experience; selves possess reflexive self-knowledge. | |
| From: E.J. Lowe (Introduction to the Philosophy of Mind [2000], Ch.10) | |
| A reaction: I would express this as 'a capacity for meta-thought'. I increasingly see that as the hallmark of homo sapiens, and the key quality I look for in assessing the intelligence of aliens. Very intelligent people are exceptionally self-aware. |
| 6670 | If my brain could survive on its own, I cannot be identical with my whole body [Lowe] |
| Full Idea: If, as seems intuitively plausible, I could survive with my brain detached from the rest of my body, I most certainly cannot be identical with my whole body. | |
| From: E.J. Lowe (Introduction to the Philosophy of Mind [2000], Ch.10) | |
| A reaction: A key mistake is to treat the notion of 'I' as all-or-nothing. My surviving brain is much more like me than my surviving kidney, but the notion of my brain saying to my family 'it's me in that jar over there' sounds wrong. It is a bit of me. |
| 6671 | It seems impossible to get generally applicable mental concepts from self-observation [Lowe] |
| Full Idea: It seems impossible for me to acquire perfectly general concepts of thought and feeling, applicable to other people as well as to myself, purely from some queer kind of mental self-observation, but this is what the observational model demands. | |
| From: E.J. Lowe (Introduction to the Philosophy of Mind [2000], Ch.10) | |
| A reaction: I don't understand the word 'queer' here, which seems part of an odd modern fashion for denigrating introspection. It is right, though, that the acquisition of general mental concepts from my mind seems to depend on analogy, which is a suspect method. |
| 6666 | All human languages have an equivalent of the word 'I' [Lowe] |
| Full Idea: Every human language appears to have a word or expression equivalent to the English word 'I'. | |
| From: E.J. Lowe (Introduction to the Philosophy of Mind [2000], Ch.10) | |
| A reaction: If this is true (what is his evidence?) I take it to be very significant support for what I take to be obvious anyway, that the mind/brain has a central controlling core, which understands and decides, and which is the most valued part of us. |
| 6625 | If qualia are causally inert, how can we even know about them? [Lowe] |
| Full Idea: The idea that 'qualia' exist but are causally inert is difficult to sustain: for if they are causally inert, how can we even know about them? | |
| From: E.J. Lowe (Introduction to the Philosophy of Mind [2000], Ch. 3) | |
| A reaction: The brain might be a special case. I can't know about a 'causally inert' object in my kitchen, but I might know about it if in some way I AM that object. Personally, though, I think everything that exists is causally active. |
| 6621 | You can only identify behaviour by ascribing belief, so the behaviour can't explain the belief [Lowe] |
| Full Idea: One must already understand what it means to ascribe to someone a belief that it is raining in order to be able to generate the items on the list of rain-behaviour, so the list cannot be used to explain what it means to ascribe to someone such a belief. | |
| From: E.J. Lowe (Introduction to the Philosophy of Mind [2000], Ch. 3) | |
| A reaction: This is thought by many to be a decisive objection of behaviourism, because it makes the enterprise hopelessly circular. If I put up an umbrella when it was dry, you would probably infer that I believed it was raining. |
| 6654 | A computer program is equivalent to the person AND the manual [Lowe] |
| Full Idea: A computer executing its program is not equivalent to the English-speaker in the Chinese Room, but to the combination of the English-speaker and the operation manual. | |
| From: E.J. Lowe (Introduction to the Philosophy of Mind [2000], Ch. 8) | |
| A reaction: Searle replies that there would be no understanding even if the person learned the manual off by heart. However, if we ask 'Is there any understanding of the universe in Newton's book?' the answer has to be 'yes'. So the manual contains understanding. |
| 6629 | Functionalism commits us to bizarre possibilities, such as 'zombies' [Lowe] |
| Full Idea: Functionalism seems to commit us to bizarre possibilities, such as 'zombies'. | |
| From: E.J. Lowe (Introduction to the Philosophy of Mind [2000], Ch. 3) | |
| A reaction: This goes with the tendency of functionalism to imply epiphenomenalism - that is, to make the intrinsic character of mental states irrelevant to thinking. I'd love to eavesdrop on two zombies in an art gallery. |
| 6623 | Functionalism can't distinguish our experiences in spectrum inversion [Lowe] |
| Full Idea: It seems that functionalism can recognise no difference between my colour experiences and yours, in the case of spectrum inversion, suggesting that it fails to characterise colour experience adequately, by omitting its qualitative character. | |
| From: E.J. Lowe (Introduction to the Philosophy of Mind [2000], Ch. 3) | |
| A reaction: This is a standard objection to functionalism, but then it is an objection to most other theories as well. Even dualism just offers a mystery as to why experiences have qualities. Observing a patch of red involves about three billion brain connections. |
| 6628 | Functionalism only discusses relational properties of mental states, not intrinsic properties [Lowe] |
| Full Idea: Functionalism has nothing positive to say about the intrinsic properties of mental states, only something about their relational properties. | |
| From: E.J. Lowe (Introduction to the Philosophy of Mind [2000], Ch. 3) | |
| A reaction: This seems to me highly significant. All references to function (e.g. in Aristotle) invite the question of what enables something to have that function. Maybe the core question of philosophy of mind is whether mental states are intrinsic or relational. |
| 6622 | Non-reductive physicalism accepts token-token identity (not type-type) and asserts 'supervenience' of mind and brain [Lowe] |
| Full Idea: The rejection of type-type identity and acceptance of token-token identity is referred to as 'non-reductive physicalism', and is usually link with the idea that mental state types are not identical with physical state types, but 'supervene' on them. | |
| From: E.J. Lowe (Introduction to the Philosophy of Mind [2000], Ch. 3) | |
| A reaction: A nice summary of the view (built on the arguments of Davidson) which has also become known as 'property dualism'. Personally I regard it as dangerous nonsense. If two things 'supervene' on one another, the first question to ask is: why? |
| 6503 | Physicalism cannot allow internal intentional objects, as brain states can't be 'about' anything [Robinson,H] |
| Full Idea: It is generally conceded by reductive physicalists that a state of the brain cannot be intrinsically about anything, for intentionality is not an intrinsic property of anything, so there can be no internal objects for a physicalist. | |
| From: Howard Robinson (Perception [1994], V.4) | |
| A reaction: Perhaps it is best to say that 'aboutness' is not a property of physics. We may say that a brain state 'represents' something, because the something caused the brain state, but representations have to be recognised |
| 6634 | Physicalists must believe in narrow content (because thoughts are merely the brain states) [Lowe] |
| Full Idea: Physicalists will, it seems, be committed to the notion of narrow content, because if a person and their counterpart are neurological duplicates, they must exemplify the same mental state types, and thus possess beliefs with the same contents. | |
| From: E.J. Lowe (Introduction to the Philosophy of Mind [2000], Ch. 4) | |
| A reaction: Very important. How many philosophers currently believe in both wide content and reductive physicalism? However, if content is physical brain-plus-environment, we might reply that the whole package must be identical for same content. Cf Idea 7884! |
| 6630 | Eliminativism is incoherent if it eliminates reason and truth as well as propositional attitudes [Lowe] |
| Full Idea: Eliminative materialism may be accused of incoherence, insofar as is threatens to eliminate reason and truth along with the propositional attitudes. | |
| From: E.J. Lowe (Introduction to the Philosophy of Mind [2000], Ch. 3) | |
| A reaction: Lowe does not enlarge on this intriguing suggestion. I don't see a threat to truth, if brain events represent the outer world, as they can do it more or less well. Logic is built on truth. Reason grows out of logic. Evidence seems okay… Hm. |
| 6648 | Some behaviourists believe thought is just suppressed speech [Lowe] |
| Full Idea: Some behaviourists have held the view that thinking just is, in effect, suppressed speech. | |
| From: E.J. Lowe (Introduction to the Philosophy of Mind [2000], Ch. 7) | |
| A reaction: He cites J.B.Watson. This would imply that infants and animals can't think. Introspecting my own case, I don't believe it. When I am navigating through a town, for example, I directly relate to my mental map; I see little sign of anything verbal. |
| 6651 | People are wildly inaccurate in estimating probabilities about an observed event [Lowe] |
| Full Idea: In the 'cab problem' (what colour was the cab in the accident?) most people estimate an 80% probability of it being a blue cab, but Bayes' Theorem calculates the probability at 41%, suggesting people put too much faith in eyewitness testimony. | |
| From: E.J. Lowe (Introduction to the Philosophy of Mind [2000], Ch. 8) | |
| A reaction: For details of the 'cab problem', see Lowe p.200. My suspicion is that people get into a tangle when confronted with numbers in a theoretical situation, but are much better at it when faced with a real life problem, like 'who ate my chocolate?' |
| 6652 | 'Base rate neglect' makes people favour the evidence over its background [Lowe] |
| Full Idea: 'Base rate neglect' (attending to the witness or evidence, and ignoring background information) is responsible for doctors exaggerating the significance of positive results in diagnosis of relatively rare medical conditions. | |
| From: E.J. Lowe (Introduction to the Philosophy of Mind [2000], Ch. 8) | |
| A reaction: This seems to be one of the clearest cases where people's behaviour is irrational, though I suspect that people are much more rational about things if the case is simple and non-numerical. However, people are very credulous about wonderful events. |
| 6655 | The 'Frame Problem' is how to program the appropriate application of general knowledge [Lowe] |
| Full Idea: The 'Frame Problem' in artificial intelligence is how to write a program which not only embodies people's general knowledge, but specifies how that knowledge is to be applied appropriately, when circumstances can't be specified in advance. | |
| From: E.J. Lowe (Introduction to the Philosophy of Mind [2000], Ch. 8) | |
| A reaction: As Lowe observes, this is a problem, but not necessarily an impossibility. There should be a way to symbolically map the concepts of knowledge onto the concepts of perception, just as we must do. |
| 6657 | Computers can't be rational, because they lack motivation and curiosity [Lowe] |
| Full Idea: Lack of motivation and curiosity are perhaps the most fundamental reason for denying that computers could be, in any literal sense, rational beings. | |
| From: E.J. Lowe (Introduction to the Philosophy of Mind [2000], Ch. 9) | |
| A reaction: I don't see why programmers couldn't move those two priorities to the top of the list in the program. When you switch on a robot, its first words could be 'Teach me something!', or 'Let's do something interesting!' Every piece of software has priorities. |
| 6656 | The Turing test is too behaviourist, and too verbal in its methods [Lowe] |
| Full Idea: The Turing test is open to the objection that it is inspired by behaviourist assumptions and focuses too narrowly on verbal evidence of intelligence. | |
| From: E.J. Lowe (Introduction to the Philosophy of Mind [2000], Ch. 8) | |
| A reaction: This is part of the objection that the test exhibits human chauvinism, and robots and aliens are wasting their time trying to pass it. You need human behaviour, especially speech, to do well. Inarticulate people can exhibit high practical intelligence. |
| 6636 | The naturalistic views of how content is created are the causal theory and the teleological theory [Lowe] |
| Full Idea: The leading naturalistic theories of what it is that confers a specific content upon a given attitudinal state are the causal theory, and the teleological theory, both of which contain serious difficulties. | |
| From: E.J. Lowe (Introduction to the Philosophy of Mind [2000], Ch. 4) | |
| A reaction: 'Causal' theories (Fodor) say the world directly causes content; 'teleological' theories (Millikan, Papineau) are based on the evolutionary purpose of content for the subject. I agree that neither seems adequate… |
| 6633 | Twin Earth cases imply that even beliefs about kinds of stuff are indexical [Lowe] |
| Full Idea: The implication of considerations of Twin Earth cases is that even beliefs about the properties of kinds of stuff are implicitly indexical, or context-dependent, in character. | |
| From: E.J. Lowe (Introduction to the Philosophy of Mind [2000], Ch. 4) | |
| A reaction: This is a significant connection, between debates about the nature of indexicals (such as 'I' and 'this') and externalism about content generally. Is there no distinction between objective reference and contextual reference? |
| 6632 | The same proposition provides contents for the that-clause of an utterance and a belief [Lowe] |
| Full Idea: We use the same that-clause ('that snow is white') to specify the contents of both a person's utterances and of their beliefs, because it is the same proposition. | |
| From: E.J. Lowe (Introduction to the Philosophy of Mind [2000], Ch. 4) | |
| A reaction: Certainly to say 'he believes that we should declare war' seems to refer to something non-linguistic, but it doesn't demonstrate that anything concrete or real is being referred to. It may be an abstract account of dispositions and desires. |
| 6631 | If propositions are abstract entities, how can minds depend on their causal powers? [Lowe] |
| Full Idea: If propositions are abstract entities, more like the objects of mathematics, it seems mysterious that states of mind should depend for their causal powers upon the propositions which allegedly constitute their 'contents'. | |
| From: E.J. Lowe (Introduction to the Philosophy of Mind [2000], 70) | |
| A reaction: Compare standard objections to Platonic Forms (e.g. Idea 3353). You can't believe in abstract propositions, but be a reductive physicalist about the mind. So propositions are dynamic brain structures. Easy. |
| 6659 | The three main theories of action involve the will, or belief-plus-desire, or an agent [Lowe] |
| Full Idea: The two alternatives to volitionism in explaining action are (firstly) certain complexes of belief and desire, and (secondly) causation by an agent. | |
| From: E.J. Lowe (Introduction to the Philosophy of Mind [2000], Ch. 9) | |
| A reaction: A helpful framework. A key test case seems to that of trying to perform an action and failing (e.g. through paralysis), and this goes against the whole 'agent' being the most basic concept. One also needs room for reasons, and this supports volitionism. |
| 6661 | Libet gives empirical support for the will, as a kind of 'executive' mental operation [Lowe] |
| Full Idea: Libet's experiments (on conscious and non-conscious choice) seem to provide empirical support for the concept of 'volition', conceived as a special kind of 'executive' mental operation. | |
| From: E.J. Lowe (Introduction to the Philosophy of Mind [2000], Ch. 9) | |
| A reaction: Despite the strictures of Hobbes (Idea 2362) and Williams (Idea 2171), the will strikes me as a genuine item, clearly observable by introspection, and offering the best explanation of human behaviour. I take it to be part of the brain's frontal lobes. |
| 6662 | We feel belief and desire as reasons for choice, not causes of choice [Lowe] |
| Full Idea: When we choose how to act in the light of our beliefs and desires, we do not feel our choices to be caused by them, but we conceive of them as giving us reasons to choose. | |
| From: E.J. Lowe (Introduction to the Philosophy of Mind [2000], Ch. 9) | |
| A reaction: I agree, though this 'feeling' could be a delusion, and we certainly don't need to start talking about a 'free' will. The best account of action seems to be that the will operates on the raw material of beliefs and desires. The will is our 'decision box'. |
| 6663 | People's actions are explained either by their motives, or their reasons, or the causes [Lowe] |
| Full Idea: When we ask why people act in the ways that they do, we are sometimes enquiring into people's motives, at other times we want to uncover their reasons, and at others we want to know the causes of their actions. | |
| From: E.J. Lowe (Introduction to the Philosophy of Mind [2000], Ch. 9) | |
| A reaction: Helpful distinctions. Any one of these explanations might be collapsed into the others. Kantians, utilitarians and contractarians can study reasons, nihilists can study causes, and virtue theorists I take to be concerned with motives. |
| 6519 | Locke's solidity is not matter, because that is impenetrability and hardness combined [Robinson,H] |
| Full Idea: Notoriously, Locke's filler for Descartes's geometrical matter, solidity, will not do, for that quality collapses on examination into a composite of the dispositional-cum-relational propery of impenetrability, and the secondary quality of hardness. | |
| From: Howard Robinson (Perception [1994], IX.3) | |
| A reaction: I would have thought the problem was that 'matter is solidity' turns out on analysis to be a tautology. We have a handful of nearly synonymous words for matter and our experiences of it, but they boil down to some 'given' thing for which we lack words. |
