| 15477 | Ontology is highly abstract physics, containing placeholders and exclusions [Martin,CB] |
| Full Idea: Ontology sets out an even more abstract model of how the world is than theoretical physics, a model that has placeholders for scientific results and excluders for tempting confusions. | |
| From: C.B. Martin (The Mind in Nature [2008], 04.6) | |
| A reaction: Most modern metaphysicians accept this account. The interesting (mildly!) question is whether physicists will accept it. If the metaphysics is really rooted in physics, a metaphysical physicist is better placed than a metaphysician knowing some physics. |
| 15471 | Truth is a relation between a representation ('bearer') and part of the world ('truthmaker') [Martin,CB] |
| Full Idea: Truth is a relation between two things - a representation (the truth 'bearer') and the world or some part of it (the 'truthmaker'). | |
| From: C.B. Martin (The Mind in Nature [2008], 03.1) | |
| A reaction: That truth is about representations seems to me to be exactly right. That it is about truthmakers is more controversial. There are well known problems with negative truths, general truths, future truths etc. I'm happy with 'facts'. |
| 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'? |
| 15484 | A property is a combination of a disposition and a quality [Martin,CB] |
| Full Idea: I take properties to have a dual nature; in virtue of possessing a property, an object possesses both a particular dispositionality and a particular qualitative character. | |
| From: C.B. Martin (The Mind in Nature [2008], 04.6) | |
| A reaction: That leaves you with the question of the relationship between the disposition and the quality. I say you must choose, and I choose the disposition. Qualities (which are partly subjective, obviously) arise from fundamental dispositions. |
| 15478 | Properties are the respects in which objects resemble, which places them in classes [Martin,CB] |
| Full Idea: If objects belong to classes in virtue of resemblances they bear to one another, they resemble one another in virtue of their properties. Objects resemble in some way or respect, and you could think of these ways or respects as 'properties'. | |
| From: C.B. Martin (The Mind in Nature [2008], 04.6) | |
| A reaction: If you pare the universe down to one object with five distinct properties, they resemble nothing, and fail this definition. Resemblance seems like the epistemology, not the ontology. |
| 15483 | Properties are ways particular things are, and so they are tied to the identity of their possessor [Martin,CB] |
| Full Idea: The redness or sphericity of this tomato cannot migrate to another tomato. This is a consequence of the idea that properties are particular ways things are. The identity of a property is bound up with the identity of its possessor. | |
| From: C.B. Martin (The Mind in Nature [2008], 04.6) | |
| A reaction: This is part of his declaration that he believes in tropes. At the very least, properties can be thought of separately, and have second-order properties that don't seem tied to the particulars. |
| 15480 | Objects are not bundles of tropes (which are ways things are, not parts of things) [Martin,CB] |
| Full Idea: The bundle theory for tropes treats properties inappositely as parts of objects. Objects can have parts, but an object's properties are not its parts, they are particular ways the object is. | |
| From: C.B. Martin (The Mind in Nature [2008], 04.6) | |
| A reaction: The 'way an object is' seems a very vague concept. Most things that get labelled as tropes are actually highly complex. Without mention of causal powers I think these discussions drift in a muddle. |
| 15489 | A property that cannot interact is worse than inert - it isn't there at all [Martin,CB] |
| Full Idea: A property that is intrinsically incapable of affecting or being affected by anything else, actual or possible, is not merely a case of inertness - it amounts to a no-thing. | |
| From: C.B. Martin (The Mind in Nature [2008], 06.6) | |
| A reaction: In the end Martin rejects Shoemaker's purely causal account of properties, but he clearly understands Shoemaker's point well. |
| 15487 | If unmanifested partnerless dispositions are still real, and are not just qualities, they can explain properties [Martin,CB] |
| Full Idea: Given a realist view of dispositions as fully actual, even without manifestations or partners, a purely dispositional account of properties has a degree of plausibility, which is enhanced because properties lack purely qualitative characterisations. | |
| From: C.B. Martin (The Mind in Nature [2008], 06.4) | |
| A reaction: In the end Martin opts for a mixed account, as in Idea 15484, but he gives reasons here for the view which I favour. If he concedes that dispositions may exist without manifestation, they must surely lack qualities. Are they not properties, then? |
| 15479 | Properties endow a ball with qualities, and with powers or dispositions [Martin,CB] |
| Full Idea: Each property endows a ball with a distinctive qualitative character and a distinctive range of powers or dispositionalities. | |
| From: C.B. Martin (The Mind in Nature [2008], 04.6) | |
| A reaction: I think this is the wrong way round. Do properties support powers, or powers support properties? I favour the latter. Properties are much vaguer than powers. Powers generate the required causation and activity. |
| 15488 | Qualities and dispositions are aspects of properties - what it exhibits, and what it does [Martin,CB] |
| Full Idea: For any intrinsic and irreducible property, what is qualitative and what is dispositional are one and the same property considered as what that property exhibits of its nature and what that property is directive and selective for in its manifestation. | |
| From: C.B. Martin (The Mind in Nature [2008], 06.6) | |
| A reaction: This is supposed to support qualities and dispositions as equal partners, but I don't see how 'what a property exhibits' can have any role in fundamental ontology. What it exhibits may be very misleading about its nature. |
| 15469 | Dispositions in action can be destroyed, be recovered, or remain unchanged [Martin,CB] |
| Full Idea: Three forms of dispositionality are illustrated by explosives (which are destroyed by manifestation), being soluble (where the dispositions is lost but recoverable), and being stable (where the disposition is unchanged). | |
| From: C.B. Martin (The Mind in Nature [2008], 02.7) | |
| A reaction: [compressed] Presumably the explosives could be recovered after the explosion, since the original elements are still there, but it would take a while. The retina remains stable by continually changing. There are no simple distinctions! |
| 15467 | Powers depend on circumstances, so can't be given a conditional analysis [Martin,CB] |
| Full Idea: Nobody believes, or ought to believe, that manifestations of powers follow upon the single event mentioned in the antecedent of the conditional independently of the circumstances. | |
| From: C.B. Martin (The Mind in Nature [2008], 02.4) | |
| A reaction: Another way of putting it would be that the behaviour of powers is more ceteris paribus than law. |
| 15466 | 'The wire is live' can't be analysed as a conditional, because a wire can change its powers [Martin,CB] |
| Full Idea: According to the conditional analysis of 'the wire is live', if the wire is touched then it gives off electricity. What ultimately defeats this analysis is the acknowledged possibility of objects gaining or losing powers. | |
| From: C.B. Martin (The Mind in Nature [2008], 02.3) | |
| A reaction: He offers his 'electro-fink' as a counterexample, where touching the wire changes its disposition. The conditional analysis is simple and clearcut, but dispositions in reality are complex and unstable. |
| 15476 | Structural properties involve dispositionality, so cannot be used to explain it [Martin,CB] |
| Full Idea: I take it as obvious that any structural property involves dispositionality and, therefore, cannot be used to 'explain' dispositionality. | |
| From: C.B. Martin (The Mind in Nature [2008], 04.3) | |
| A reaction: I think this is the right way round. The so-called 'categorical' properties seem to be close in nature to the 'structural' properties. |
| 15465 | Structures don't explain dispositions, because they consist of dispositions [Martin,CB] |
| Full Idea: It is self-defeating to try to explain dispositionality in terms of structural states because structural states are themselves dispositional. | |
| From: C.B. Martin (The Mind in Nature [2008], 01.2) | |
| A reaction: No doubt structures have dispositions, but are they entirely dispositional? Might there be 'emergent' dispositions which can only be explained by the structure itself, rather than by the dispositions that make up the structure? |
| 15481 | I favour the idea of a substratum for properties; spacetime seems to be just a bearer of properties [Martin,CB] |
| Full Idea: I favour the old idea of substratum: the haver of properties not itself had as a property. Space-time might itself be the bearer of properties, not itself borne as a property. | |
| From: C.B. Martin (The Mind in Nature [2008], 04.6) | |
| A reaction: A very nice idea. The choice is between saying either that fundamentals like space-time and physical fields are the propertyless bearers of properties, or that they purely consist of properties (so properties are fundamental, not substrata). |
| 15474 | Properly understood, wholes do no more causal work than their parts [Martin,CB] |
| Full Idea: There is no causal work for the whole that is not done by the parts, provided the complex role of the parts is fully appreciated. | |
| From: C.B. Martin (The Mind in Nature [2008], 04.1) | |
| A reaction: It seems like a truth that because some parts are doing particular causal work (e.g. glue), the whole can acquire causal powers that the mereological sum of parts lacks. |
| 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. |
| 15486 | Only abstract things can have specific and full identity specifications [Martin,CB] |
| Full Idea: Abstract entities (as nonspatiotemporal) seem to be the only candidates for specific and full identity specifications. | |
| From: C.B. Martin (The Mind in Nature [2008], 05.2 n1) | |
| A reaction: Martin says that only the 'mad logician' seeks such specifications elsewhere. Some people like persons to have perfect identity. God is a popular candidate too. Can objects have perfect 'macroscopic' identity? |
| 15475 | The concept of 'identity' must allow for some changes in properties or parts [Martin,CB] |
| Full Idea: We must avoid a use of 'identity' that implies that any entity over time must be said to lack continuing identity simply because it has changed properties or has lost, added, or had substituted some parts. | |
| From: C.B. Martin (The Mind in Nature [2008], 04.3) | |
| A reaction: This may the key area where the logical-mathematical type of philosophy comes into contact with the natural-metaphysical type. Imagine Martin's concept of 'identity' in mathematics. π changes to 3.1387... during the calculation! |
| 15472 | It is pointless to say possible worlds are truthmakers, and then deny that possible worlds exist [Martin,CB] |
| Full Idea: To claim that the truthmaker for a counterfactual, for example, is a set of possible worlds, but to deny that these worlds really exist, seems pointless. | |
| From: C.B. Martin (The Mind in Nature [2008], 03.3) | |
| A reaction: Lewis therefore argues that they do exist. Martin argues that possible worlds are not truthmakers. He rests his account of modality on dispositions. I prefer Martin. |
| 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'. |
| 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. |
| 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. |
| 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. |
| 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. |
| 15492 | Explanations are mind-dependent, theory-laden, and interest-relative [Martin,CB] |
| Full Idea: Explanations are mind-dependent, theory-laden, and interest-relative. | |
| From: C.B. Martin (The Mind in Nature [2008], 10.2) | |
| A reaction: I don't think you can rule out the 'real' explanation, as the one dominant causal predecessor, such as the earthquake producing a tsunami. |
| 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? |
| 15495 | Analogy works, as when we eat food which others seem to be relishing [Martin,CB] |
| Full Idea: The long-derided way of analogy works! Otherwise why, when someone else is relishing a food we have not tried, is it reasonable for us to try it ourselves? | |
| From: C.B. Martin (The Mind in Nature [2008], 12.2) | |
| A reaction: Why wouldn't we rush to eat something an animal was relishing? Nice idea. |
| 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. |
| 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. |
| 15493 | Memory requires abstraction, as reminders of what cannot be fully remembered [Martin,CB] |
| Full Idea: Selectivity and abstraction are required for the development of memory, because reminders and promptings are rarely replicas of what is being remembered. | |
| From: C.B. Martin (The Mind in Nature [2008], 10.3) | |
| A reaction: I take the key idea of mental life to be that of a 'label'. This need not be verbal, so 'conceptual label'. It could be an image, as on a road sign. Labelling is the most indispensable aspect of thought. We label objects, parts, properties and groups. |
| 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? |
| 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. |
| 7903 | The six perfections are giving, morality, patience, vigour, meditation, and wisdom [Nagarjuna] |
| Full Idea: The six perfections are of giving, morality, patience, vigour, meditation, and wisdom. | |
| From: Nagarjuna (Mahaprajnaparamitashastra [c.120], 88) | |
| A reaction: What is 'morality', if giving is not part of it? I like patience and vigour being two of the virtues, which immediately implies an Aristotelian mean (which is always what is 'appropriate'). |
| 15485 | Instead of a cause followed by an effect, we have dispositions in reciprocal manifestation [Martin,CB] |
| Full Idea: The two-event cause-and-effect view is easily avoided and replaced by the view of mutual manifestations of reciprocal disposition partners, suggesting a natural contemporaneity. | |
| From: C.B. Martin (The Mind in Nature [2008], 05.1) | |
| A reaction: This view, which I find much more congenial than the traditional one, is explored in the ideas of Mumford and Anjum. |
| 15491 | Causation should be explained in terms of dispositions and manifestations [Martin,CB] |
| Full Idea: Disposition and manifestation are the basic categories by means of which cause and effect are to be explained. | |
| From: C.B. Martin (The Mind in Nature [2008], 07.8) | |
| A reaction: 'Manifestation' sounds a bit subjective. The manifestation evident to us may not indicate what is really going on below the surface. I like his basic picture. |
| 15468 | Causal counterfactuals are just clumsy linguistic attempts to indicate dispositions [Martin,CB] |
| Full Idea: 'Causal' counterfactuals have a place, of course, but only as clumsy and inexact linguistic gestures to dispositions, and they should be kept in that place. | |
| From: C.B. Martin (The Mind in Nature [2008], 02.6) | |
| A reaction: Counterfactuals only seem to give a regularity account of causation, by correlating an effect with a minimal context which will give rise to it. Surely dispositions run deeper than that? |
| 15470 | Causal laws are summaries of powers [Martin,CB] |
| Full Idea: Causal laws are summaries of what entities are capable and incapable of. | |
| From: C.B. Martin (The Mind in Nature [2008], 02.8) | |
| A reaction: That's a pretty good formulation. Personally I favour a Humean analysis, perhaps along Lewis's lines, but on a basis of real powers. This remark of Martin's has got me rethinking. |
| 15482 | We can't think of space-time as empty and propertyless, and it seems to be a substratum [Martin,CB] |
| Full Idea: It makes no sense in ontology or modern physics to think of space-time as empty and propertyless. Space-time nicely fulfils the condition of a substratum. | |
| From: C.B. Martin (The Mind in Nature [2008], 04.6) | |
| A reaction: At the very least, space-time seems to be 'curved', so it had better be something. Time has properties like being transitive. Space-time (or fields) might be a pure bundle of properties (the only pure bundle?), rather than a substratum. |
