17275 | Realist metaphysics concerns what is real; naive metaphysics concerns natures of things [Fine,K] |
Full Idea: We may broadly distinguish between two main branches of metaphysics: the 'realist' or 'critical' branch is concerned with what is real (tense, values, numbers); the 'naive' or 'pre-critical' branch concerns natures of things irrespective of reality. | |
From: Kit Fine (Guide to Ground [2012], 1.02) | |
A reaction: [compressed] The 'natures' of things are presumably the essences. He cites 3D v 4D objects, and the status of fictional characters, as examples of the second type. Fine says ground is central to realist metaphysics. |
3426 | If one theory is reduced to another, we make fewer independent assumptions about the world [Kim] |
Full Idea: If we reduce one theory to another, we reduce the number of independent assumptions about the world. | |
From: Jaegwon Kim (Philosophy of Mind [1996], p.215) |
17282 | Truths need not always have their source in what exists [Fine,K] |
Full Idea: There is no reason in principle why the ultimate source of what is true should always lie in what exists. | |
From: Kit Fine (Guide to Ground [2012], 1.03) | |
A reaction: This seems to be the weak point of the truthmaker theory, since truths about non-existence are immediately in trouble. Saying reality makes things true is one thing, but picking out a specific bit of it for each truth is not so easy. |
17283 | If the truth-making relation is modal, then modal truths will be grounded in anything [Fine,K] |
Full Idea: The truth-making relation is usually explicated in modal terms, ...but this lets in far too much. Any necessary truth will be grounded by anything. ...The fact that singleton Socrates exists will be a truth-maker for the proposition that Socrates exists. | |
From: Kit Fine (Guide to Ground [2012], 1.03) | |
A reaction: If truth-makers are what has to 'exist' for something to be true, then maybe nothing must exist for a necessity to be true - in which case it has no truth maker. Or maybe 2 and 4 must 'exist' for 2+2=4? |
17286 | Logical consequence is verification by a possible world within a truth-set [Fine,K] |
Full Idea: Under the possible worlds semantics for logical consequence, each sentence of a language is associated with a truth-set of possible worlds in which it is true, and then something is a consequence if one of these worlds verifies it. | |
From: Kit Fine (Guide to Ground [2012], 1.10) | |
A reaction: [compressed, and translated into English; see Fine for more symbolic version; I'm more at home in English] |
17272 | 2+2=4 is necessary if it is snowing, but not true in virtue of the fact that it is snowing [Fine,K] |
Full Idea: It is necessary that if it is snowing then 2+2=4, but the fact that 2+2=4 does not obtain in virtue of the fact that it is snowing. | |
From: Kit Fine (Guide to Ground [2012], 1.01) | |
A reaction: Critics dislike 'in virtue of' (as vacuous), but I can't see how you can disagree with this obvervation of Fine's. You can hardly eliminate the word 'because' from English, or say p is because of some object. We demand the right to keep asking 'why?'! |
17276 | If you say one thing causes another, that leaves open that the 'other' has its own distinct reality [Fine,K] |
Full Idea: It will not do to say that the physical is causally determinative of the mental, since that leaves open the possibility that the mental has a distinct reality over and above that of the physical. | |
From: Kit Fine (Guide to Ground [2012], 1.02) | |
A reaction: The context is a defence of grounding, so that if we say the mind is 'grounded' in the brain, we are saying rather more than merely that it is caused by the brain. A ghost might be 'caused' by a bar of soap. Nice. |
17284 | An immediate ground is the next lower level, which gives the concept of a hierarchy [Fine,K] |
Full Idea: It is the notion of 'immediate' ground that provides us with our sense of a ground-theoretic hierarchy. For any truth, we can take its immediate grounds to be at the next lower level. | |
From: Kit Fine (Guide to Ground [2012], 1.05 'Mediate') | |
A reaction: Are the levels in the reality, the structure or the descriptions? I vote for the structure. I'm defending the idea that 'essence' picks out the bottom of a descriptive level. |
17285 | 'Strict' ground moves down the explanations, but 'weak' ground can move sideways [Fine,K] |
Full Idea: We might think of strict ground as moving us down in the explanatory hierarchy. ...Weak ground, on the other hand, may also move us sideways in the explanatory hierarchy. | |
From: Kit Fine (Guide to Ground [2012], 1.05 'Weak') | |
A reaction: This seems to me rather illuminating. For example, is the covering law account of explanation a 'sideways' move in explanation. Are inductive generalities mere 'sideways' accounts. Both fail to dig deeper. |
17288 | We learn grounding from what is grounded, not what does the grounding [Fine,K] |
Full Idea: It is the fact to be grounded that 'points' to its ground and not the grounds that point to what they ground. | |
From: Kit Fine (Guide to Ground [2012], 1.11) | |
A reaction: What does the grounding may ground all sorts of other things, but what is grounded only has one 'full' (as opposed to 'partial', in Fine's terminology) ground. He says this leads to a 'top-down' approach to the study of grounds. |
17281 | If grounding is a relation it must be between entities of the same type, preferably between facts [Fine,K] |
Full Idea: In so far as ground is regarded as a relation it should be between entities of the same type, and the entities should probably be taken as worldly entities, such as facts, rather than as representational entities, such as propositions. | |
From: Kit Fine (Guide to Ground [2012], 1.02) | |
A reaction: That's more like it (cf. Idea 17280). The consensus of this discussion seems to point to facts as the best relata, for all the vagueness of facts, and the big question of how fine-grained facts should be (and how dependent they are on descriptions). |
17280 | Ground is best understood as a sentence operator, rather than a relation between predicates [Fine,K] |
Full Idea: Ground is perhaps best regarded as an operation (signified by an operator on sentences) rather than as a relation (signified by a predicate) | |
From: Kit Fine (Guide to Ground [2012], 1.02) | |
A reaction: Someone in this book (Koslicki?) says this is to avoid metaphysical puzzles over properties. I don't like the idea, because it makes grounding about sentences when it should be about reality. Fine is so twentieth century. Audi rests ground on properties. |
17290 | Only metaphysical grounding must be explained by essence [Fine,K] |
Full Idea: If the grounding relation is not metaphysical (such as normative or natural grounding), there is no need for there to be an explanation of its holding in terms of the essentialist nature of the items involved. | |
From: Kit Fine (Guide to Ground [2012], 1.11) | |
A reaction: He accepts that some things have partial grounds in different areas of reality. |
17274 | Philosophical explanation is largely by ground (just as cause is used in science) [Fine,K] |
Full Idea: For philosophers interested in explanation - of what accounts for what - it is largely through the notion of ontological ground that such questions are to be pursued. Ground, if you like, stands to philosophy as cause stands to science. | |
From: Kit Fine (Guide to Ground [2012], 1.02) | |
A reaction: Why does the ground have to be 'ontological'? It isn't the existence of the snow that makes me cold, but the fact that I am lying in it. Better to talk of 'factual' ground (or 'determinative' ground), and then causal grounds are a subset of those? |
17278 | We can only explain how a reduction is possible if we accept the concept of ground [Fine,K] |
Full Idea: It is only by embracing the concept of a ground as a metaphysical form of explanation in its own right that one can adequately explain how a reduction of the reality of one thing to another should be understood. | |
From: Kit Fine (Guide to Ground [2012], 1.02) | |
A reaction: I love that we are aiming to say 'how' a reduction should be understood, and not just 'that' it exists. I'm not sure about Fine's emphasis on explaining 'realities', when I think we are after more like structural relations or interconnected facts. |
3431 | Supervenience suggest dependence without reduction (e.g. beauty) [Kim] |
Full Idea: Supervenience opens up the possibility of a relationship that gives us determination, or dependence, without reduction (as beauty supervenes on physical properties, but can't be given a physical definition). | |
From: Jaegwon Kim (Philosophy of Mind [1996], p.223) | |
A reaction: Beauty is a bad analogy, since it rather obviously involves a beholder. There is nothing more to a statue than a substance of a certain shape. There are no good analogies for this sort of supervenience, because it doesn't exist. |
3437 | 'Physical facts determine all the facts' is the physicalists' slogan [Kim] |
Full Idea: Physicalists are fond of saying that physical facts determine all the facts. | |
From: Jaegwon Kim (Philosophy of Mind [1996], p.232) | |
A reaction: I totally agree with this slogan. As a view, it seems to me that it is reinforced by essentialism (see the ideas of Brian Ellis), which gives some indication of how facts are physically determined, and why there is no alternative. |
17287 | Facts, such as redness and roundness of a ball, can be 'fused' into one fact [Fine,K] |
Full Idea: Given any facts, there will be a fusion of those facts. Given the facts that the ball is red and that it is round, there is a fused fact that it is 'red and round'. | |
From: Kit Fine (Guide to Ground [2012], 1.10) | |
A reaction: This is how we make 'units' for counting. Any type of thing which can be counted can be fused, such as the first five prime numbers, forming the 'first' group for some discussion. Any objects can be fused to make a unit - but is it thereby a 'unity'? |
3430 | Resemblance or similarity is the core of our concept of a property [Kim] |
Full Idea: Resemblance or similarity is the very core of our concept of a property. | |
From: Jaegwon Kim (Philosophy of Mind [1996], p.219) |
3432 | Is weight a 'resultant' property of water, but transparency an 'emergent' property? [Kim] |
Full Idea: Emergent properties are said to be irreducible to, and unpredictable from, the lower-level phenomena from which they emerge (as weight is a 'resultant' property, but the transparency of water is an 'emergent' property). | |
From: Jaegwon Kim (Philosophy of Mind [1996], p.228) | |
A reaction: So weight is predictable, but transparency is a surprise? But presumably the transparency of water is totally predictable, once you understand it. Emergent properties are either dualist or reducible, in my view. |
3434 | Emergent properties are 'brute facts' (inexplicable), but still cause things [Kim] |
Full Idea: For the emergentist why pain emerges when C-fibres are excited remains a mystery (a 'brute fact'), but such properties then take on a life of their own as 'downward causation'. | |
From: Jaegwon Kim (Philosophy of Mind [1996], p.229) | |
A reaction: I don't think there are any 'brute facts', except perhaps at the lowest level of physics. Whatever happened to the principle of sufficient reason? Is the mind like God - a causal source which is uncaused? |
15148 | Powers give explanations, without being necessary for some class membership [Chakravartty] |
Full Idea: Powers explain behaviours regardless of whether they are necessary for membership in a particular class of things. | |
From: Anjan Chakravarrty (Inessential Aristotle: Powers without Essences [2012], 3) | |
A reaction: This seems right, and is important for driving a wedge between powers and essences. If there are essences, they are not simply some bunch of powers. |
3436 | Should properties be individuated by their causal powers? [Kim] |
Full Idea: Arguably, properties must be individuated in terms of their causal powers. | |
From: Jaegwon Kim (Philosophy of Mind [1996], p.230) |
15145 | A kind essence is the necessary and sufficient properties for membership of a class [Chakravartty] |
Full Idea: The modern concept of a kind essence is a set of intrinsic properties that are individually necessary and jointly sufficient for the membership of something in a class of things, or 'kind'. | |
From: Anjan Chakravarrty (Inessential Aristotle: Powers without Essences [2012], 2) | |
A reaction: I am always struck by the problem that the kind itself is constructed from the individuals, so circularity always seems to loom. |
15147 | Cluster kinds are explained simply by sharing some properties, not by an 'essence' [Chakravartty] |
Full Idea: The fact that members of some cluster kinds are subjects of causal generalizations reflects the degree to which they share causally efficacious properties, not the fact that they may be composed of essence kinds per se. | |
From: Anjan Chakravarrty (Inessential Aristotle: Powers without Essences [2012], 2) | |
A reaction: I think this is right. I am a fan of individual essences, but not of kind essences. I take kinds, and kind explanations, to be straightforward inductive generalisations from individuals. Extreme stabilities give the illusion of a kind essence. |
17279 | Even a three-dimensionalist might identify temporal parts, in their thinking [Fine,K] |
Full Idea: Even the three-dimensionalist might be willing to admit that material things have temporal parts. For given any persisting object, he might suppose that 'in thought' we could mark out its temporal segments or parts. | |
From: Kit Fine (Guide to Ground [2012], 1.02) | |
A reaction: A big problem with temporal parts is how thin they are. Hawley says they are as fine-grained as time itself, but what if time has no grain? How thin can you 'think' a temporal part to be? Fine says imagined parts are grounded in things, not vice versa. |
3406 | Counterfactuals are either based on laws, or on nearby possible worlds [Kim, by PG] |
Full Idea: For counterfactuals there is the 'nomic-derivational' approach (which logically derives them from laws), and the 'possible world' approach (based on truth in worlds close to the actual one). | |
From: report of Jaegwon Kim (Philosophy of Mind [1996], p.141) by PG - Db (ideas) |
17289 | Every necessary truth is grounded in the nature of something [Fine,K] |
Full Idea: It might be held as a general thesis that every necessary truth is grounded in the nature of certain items. | |
From: Kit Fine (Guide to Ground [2012], 1.11) | |
A reaction: [He cites his own 1994 for this] I'm not sure if I can embrace the 'every' in this. I would only say, more cautiously, that I can only make sense of necessity claims when I see their groundings - and I don't take a priori intuition as decent grounding. |
17273 | Each basic modality has its 'own' explanatory relation [Fine,K] |
Full Idea: I am inclined to the view that ....each basic modality should be associated with its 'own' explanatory relation. | |
From: Kit Fine (Guide to Ground [2012], 1.01) | |
A reaction: He suggests that 'grounding' connects the various explanatory relations of the different modalities. I like this a lot. Why assert any necessity without some concept of where the necessity arises, and hence where it is grounded? You've got to eat. |
17291 | We explain by identity (what it is), or by truth (how things are) [Fine,K] |
Full Idea: I think it should be recognised that there are two fundamentally different types of explanation; one is of identity, or of what something is; and the other is of truth, or of how things are. | |
From: Kit Fine (Guide to Ground [2012], 1.11) |
17271 | Is there metaphysical explanation (as well as causal), involving a constitutive form of determination? [Fine,K] |
Full Idea: In addition to scientific or causal explanation, there maybe a distinctive kind of metaphysical explanation, in which explanans and explanandum are connected, not through some causal mechanism, but through some constitutive form of determination. | |
From: Kit Fine (Guide to Ground [2012], Intro) | |
A reaction: I'm unclear why determination has to be 'constitutive', since I would take determination to be a family of concepts, with constitution being one of them, as when chess pieces determine a chess set. Skip 'metaphysical'; just have Determinative Explanation. |
15144 | Explanation of causal phenomena concerns essential kinds - but also lack of them [Chakravartty] |
Full Idea: Scientific practices such as prediction and explanation regarding causal phenomena are concerned not merely with kinds having essences, but also with kinds lacking them. | |
From: Anjan Chakravarrty (Inessential Aristotle: Powers without Essences [2012], 1) | |
A reaction: Not quite clear what he has in mind, but explanation should certainly involve a coherent picture, and not just the citation of some underlying causal mechanism. |
3368 | Mind is basically qualities and intentionality, but how do they connect? [Kim] |
Full Idea: It is generally held that there are two broad categories of mental phenomena - qualitative states and intentional states (but what do they have in common?). | |
From: Jaegwon Kim (Philosophy of Mind [1996], p. 23) | |
A reaction: I am happy to accept this orthodox modern analysis. Putting it more simply: minds exist to enable experience and thought. I judge a priori that the two aspects are not separate. Qualia exist to serve thought, and qualia are necessary for thought. |
3392 | Mind is only interesting if it has causal powers [Kim] |
Full Idea: Unless mental properties have causal powers, there would be little point in worrying about them. | |
From: Jaegwon Kim (Philosophy of Mind [1996], p.118) | |
A reaction: This doesn't, on its own, actually rule out epiphenomenalism, but it does show why it barely qualifies as a serious theory. One might, in fact, say that we simply can't worry about something which has no causal powers. The powers might not be physical… |
3396 | Experiment requires mental causation [Kim] |
Full Idea: Experimentation presupposes mental-to-physical causation and is impossible without it. | |
From: Jaegwon Kim (Philosophy of Mind [1996], p.128) | |
A reaction: So an epiphenomenalist can't do experiments? Kim implies that there is some special mental assessment of the feedback from physical events, but presumably a robot or a zombie could do experiments. Spiders do experiments. |
3397 | Beliefs cause other beliefs [Kim] |
Full Idea: A brief reflection makes it evident that most of our beliefs are generated by other beliefs we hold, and "generation" here could only mean causal generation. | |
From: Jaegwon Kim (Philosophy of Mind [1996], p.128) | |
A reaction: This seems right, and yet implies an uncomfortable determinism, as if all our beliefs just happened to us. I don't claim proper free will, but I do say there is an element in belief formation which is just caused by bunches of beliefs. Call it character. |
3367 | Both thought and language have intentionality [Kim] |
Full Idea: Mental states are not the only things which exhibit intentionality - words and sentences can also refer to or represent facts or states of affairs. | |
From: Jaegwon Kim (Philosophy of Mind [1996], p. 22) | |
A reaction: This points to Searle's distinction between 'intrinsic' and 'derived' intentionality (see Idea 3465). We must now explain the difference between verbal intentionality and non-verbal intentionality (both as phenomena, and as information). |
3365 | Intentionality involves both reference and content [Kim] |
Full Idea: There is referential intentionality (that some of our thoughts refer, or are 'about' something) and content intentionality (that propositional attitudes have content or meaning, often expressed by full sentences). | |
From: Jaegwon Kim (Philosophy of Mind [1996], p. 21) | |
A reaction: So could these be the external and internal components of content? Which might be the causal/historical component, and the descriptive component? Which might be known by (indirect) acquaintance and description? |
3360 | Are pains pure qualia, or do they motivate? [Kim] |
Full Idea: Are pains only sensory events, or do they also have a motivational component (e.g. aversiveness)? | |
From: Jaegwon Kim (Philosophy of Mind [1996], p. 7) | |
A reaction: A nice question. Given the occasional genuine masochist, and the way some people love tastes that others hate, it has always seemed to me that aversiveness was not a necessary property of pain. I couldn't train myself to like pain, though… |
3366 | Pain has no reference or content [Kim] |
Full Idea: Some mental phenomena - in particular, sensations like tickles and pains - do not seem to exhibit either reference or content. | |
From: Jaegwon Kim (Philosophy of Mind [1996], p. 21) | |
A reaction: This could be challenged. These sensations cannot be had without a bodily location, and they give information about possible contact or damage. |
3389 | Inverted qualia and zombies suggest experience isn't just functional [Kim] |
Full Idea: If inverted qualia, or absent qualia (zombies), are possible in functionally equivalent systems, qualia are not capturable by functional definitions. | |
From: Jaegwon Kim (Philosophy of Mind [1996], p.114) | |
A reaction: The point here (I take it) is that we don't have to go the whole hog of saying the qualia are therefore epiphenomenal, although that is implied. How about a fail-safe situation, where qualia do it for me, and something else does the same for zombies? |
3391 | Crosswiring would show that pain and its function are separate [Kim, by PG] |
Full Idea: If you crosswire your 'pain box' and your 'itch box', the functionalist says you are in pain if the inputs and outputs are for pain, even though the feeling is of an itch. | |
From: report of Jaegwon Kim (Philosophy of Mind [1996], p.115) by PG - Db (ideas) | |
A reaction: If functionalists would indeed say this, then the objection seems to me almost conclusive. But they might well say that such simple crosswiring won't work. Itching won't produce pain behaviour - it lacks the correct function. |
3422 | Externalism about content makes introspection depend on external evidence [Kim] |
Full Idea: Externalism about content would have the consequence that most of our knowledge of our own intentional states is indirect and must be based on external evidence. | |
From: Jaegwon Kim (Philosophy of Mind [1996], p.207) | |
A reaction: I think this is a confusion, endemic in discussions of externalism. If what Shakespeare meant by 'water' is H2O, or Putnam means by 'elm' what experts say, the point is that their meanings are NOT part of their intentional states, which are bookmarks. |
3412 | How do we distinguish our anger from embarrassment? [Kim] |
Full Idea: How do we know that we are angry rather than embarrassed? | |
From: Jaegwon Kim (Philosophy of Mind [1996], p.159) | |
A reaction: A very nice question, because the only answer I (or anyone?) can think of is that they are distinguished by their content. Event A is annoying, while event B is embarrassing. Either of those feelings is almost inconceivable without its content. |
3363 | We often can't decide what emotion, or even sensation, we are experiencing [Kim] |
Full Idea: It is not always easy for us to determine what emotion (or even physical sensations) we are experiencing. | |
From: Jaegwon Kim (Philosophy of Mind [1996], p. 18) | |
A reaction: Confused sensations are, I would have thought, rare. Emotions, I think, are only confused when they are weak, and then a lot of the confusion is merely verbal. Our body and intuitions understand the feeling well enough, but we lack the vocabulary. |
3409 | Mental substance causation makes physics incomplete [Kim] |
Full Idea: Since Cartesian dualism implies causation from outside of the physical domain, this means there can be no complete physical theory of the physical domain. | |
From: Jaegwon Kim (Philosophy of Mind [1996], p.147) | |
A reaction: This, I think, should be taken as a very strong argument against dualism, rather than as bad news for physics. Some exception might make the closure of physics impossible, but the claim that our brain is the exception looks highly suspect. |
3399 | If epiphenomenalism were true, we couldn't report consciousness [Kim] |
Full Idea: If epiphenomenalism were true, it would be a mystery how such things could be known to us. | |
From: Jaegwon Kim (Philosophy of Mind [1996], p.130) | |
A reaction: If a brain were asked whether it was conscious, it would presumably say 'yes', but (if epiphenomenalism were true) the cause of that would have to be brain events, and NOT information that it is conscious, which the brain could not have. Big objection. |
3390 | Are inverted or absent qualia coherent ideas? [Kim] |
Full Idea: Some philosophers doubt the coherence of the very idea of inverted or absent qualia. | |
From: Jaegwon Kim (Philosophy of Mind [1996], p.115) | |
A reaction: The possibility of inverted qualia with identical brain structures strikes me as nil, but it would be odd to deny that qualia could be changed by brain surgery, given that insects can see ultra-violet, and some people are colourblind. |
3414 | What could demonstrate that zombies and inversion are impossible? [Kim] |
Full Idea: Is there anything about the qualitative characters of mental states which, should we come to know it, would convince us that zombies and qualia inversion are not really possible? | |
From: Jaegwon Kim (Philosophy of Mind [1996], p.171) | |
A reaction: The issue is what causes the qualitative states, not their 'characters'. This strikes me as falling into the trap of thinking that 'what it is like to be..' is a crucial issue. I think zombies are impossible, but not because I experience redness. |
3359 | Cartesian dualism fails because it can't explain mental causation [Kim] |
Full Idea: Its inability to explain the possibility of "mental causation" doomed Cartesian dualism. | |
From: Jaegwon Kim (Philosophy of Mind [1996], p. 4) | |
A reaction: This is a modern way of stating the interaction problem. Personally I am inclined to think that dualism was doomed by the spread of the scientific materialist view to every other corner of our knowledge except the mind. Plenty of causes baffle us. |
3369 | Logical behaviourism translates mental language to behavioural [Kim] |
Full Idea: Logical behaviourism says any meaningful statement about mental phenomena can be translated without loss of content into a statement solely about behavioural and physical phenomena. | |
From: Jaegwon Kim (Philosophy of Mind [1996], p. 29) | |
A reaction: Also called analytical behaviourism. If we are supposed to infer the ontology of mental states from language, this makes me cross. Maybe we only discuss mentality in behavioural terms because we are epistemologically, and hence linguistically, limited. |
3428 | Behaviourism reduces mind to behaviour via bridging principles [Kim] |
Full Idea: Behaviourism can be considered as an attempt to reduce the mental to the physical via definitional bridge principles (every mental expression being given a behavioural definition). | |
From: Jaegwon Kim (Philosophy of Mind [1996], p.217) | |
A reaction: Effectively these would (if they had been discoverable) have been the elusive psycho-physical laws (which Davidson says do not exist). The objection to behaviourism is precisely that there is no fixed behaviour attached to a given mental state. |
3380 | Are dispositions real, or just a type of explanation? [Kim] |
Full Idea: Functionalists take a "realist" approach to dispositions whereas the behaviourist embraces an "instrumentalist" line. | |
From: Jaegwon Kim (Philosophy of Mind [1996], p. 78) | |
A reaction: A helpful distinction, which immediately shows why functionalism is superior to behaviourism. There must be some explanation of mental dispositions, and the instrumental view is essentially a refusal to think about the real problem. |
3371 | Behaviour depends on lots of mental states together [Kim] |
Full Idea: Mind-to-behaviour connections are always defeasible - by the occurrence of a further mental state. | |
From: Jaegwon Kim (Philosophy of Mind [1996], p. 35) | |
A reaction: But then an object's falling under gravity is always defeasible, by someone catching it first. This popular idea is meant to show that there could, as Davidson puts it, 'no psycho-physical laws', but I suspect the laws are just complex, like weather laws. |
3372 | Behaviour is determined by society as well as mental states [Kim] |
Full Idea: The factors that determine exactly what you are doing when you produce a physical gesture include the customs, habits and conventions that are in force, so it is unlikely that anyone could produce correct behavioural definitions of mental terms. | |
From: Jaegwon Kim (Philosophy of Mind [1996], p. 36) | |
A reaction: This problem can be added to the problem that it is hard to specify behaviour without reference to mentalistic terms. The point is clearly right, as what I am doing when I wave my hand in the air will depend on all sorts of conventions and expectations. |
3373 | Snakes have different pain behaviour from us [Kim] |
Full Idea: If it is an analytic truth that anyone in pain has a tendency to wince or groan, what about snakes? | |
From: Jaegwon Kim (Philosophy of Mind [1996], p. 37) | |
A reaction: Snakes do, however, exhibit what looks like 'I really don't like that' behaviour, and their rapid avoidance movements are identical to ours. On the other hand, I'm not quite sure what a snake does what it has a stomach upset. I see Kim's point. |
3370 | What behaviour goes with mathematical beliefs? [Kim] |
Full Idea: Is there even a loosely definable range of bodily behaviour that is characteristically exhibited by people when they believe, say, that there is no largest prime number? | |
From: Jaegwon Kim (Philosophy of Mind [1996], p. 32) | |
A reaction: This is a highly persuasive argument against behaviourism. Very abstract and theoretical thoughts have no related behaviour, especially among non-mathematicians. I probably believe this idea about numbers, but I can't think what to do about it. |
3379 | Neurons seem to be very similar and interchangeable [Kim] |
Full Idea: Most neurons, it has been said, are pretty much alike and largely interchangeable. | |
From: Jaegwon Kim (Philosophy of Mind [1996], p. 76) | |
A reaction: This fact, if true, is highly significant, because the correct theory of the mind must therefore be some sort of functionalism. If what a neuron is is insignificant, then what it does must be what matters. |
3388 | Machine functionalism requires a Turing machine, causal-theoretical version doesn't [Kim] |
Full Idea: Machine functionalism requires a mental state to be a physical realisation of a Turing machine; causal-theoretical functionalism only requires that there be appropriate "internal states". | |
From: Jaegwon Kim (Philosophy of Mind [1996], p.112) | |
A reaction: Searle's objection to the Turing machine version seems good - that such a machine has an implicit notion of a user/interpreter, which is absent from this theory of mind. |
3384 | The person couldn't run Searle's Chinese Room without understanding Chinese [Kim] |
Full Idea: It is by no means clear that any human could manage to do what Searle imagines himself to be doing in the Chinese Room - that is, short of throwing away the rule book and learning some real Chinese. | |
From: Jaegwon Kim (Philosophy of Mind [1996], p.100) | |
A reaction: It is not clear how a rule book could contain answers to an infinity of possible questions. The Chinese Room is just a very poor analogy with what is envisaged in the project of artificial intelligence. |
3393 | How do functional states give rise to mental causation? [Kim] |
Full Idea: On the functionalist account of mental properties, just where does a mental property get its causal powers? | |
From: Jaegwon Kim (Philosophy of Mind [1996], p.118) | |
A reaction: That is the key problem. Something can only have a function if it has intrinsic powers (corkscrews are rigid and helix-shaped). It can't be irrelevant that pain hurts. |
3439 | Reductionism gets stuck with qualia [Kim] |
Full Idea: The main obstacle to mind-body reduction is qualia. | |
From: Jaegwon Kim (Philosophy of Mind [1996], p.236) | |
A reaction: Personally I am also impressed by Leibniz's Mill (Idea 2109). No microscope could ever reveal the contents of thought. How can it be so vivid for the owner, but totally undetectable to an observer? |
3427 | Reductionism is impossible if there aren't any 'bridge laws' between mental and physical [Kim] |
Full Idea: Most antireductionist arguments focus on the unavailability of bridge laws to effect the reduction of psychological theory to physical theory (as found in reducing the gas laws to theories about molecules). | |
From: Jaegwon Kim (Philosophy of Mind [1996], p.216) | |
A reaction: Reduction can, of course, be achieved by identity rather than by bridge laws. I would say that all that prevents us from predicting mental events from physical ones is the sheer complexity involved. Cf. predicting the detailed results of an explosion. |
3376 | We can't assess evidence about mind without acknowledging phenomenal properties [Kim] |
Full Idea: In order to make sense of the empirical character of mind-brain identity, we must acknowledge the existence of phenomenal properties. | |
From: Jaegwon Kim (Philosophy of Mind [1996], p. 66) | |
A reaction: Mind-brain identity is, of course, an ontological theory, not an epistemological one (like empiricism). I suspect that the basis for my belief in reductive physicalism is an intuition, which I am hoping is a rational intuition. Cf. Idea 3989. |
3424 | Most modern physicalists are non-reductive property dualists [Kim] |
Full Idea: The most widely accepted form of physicalism today is the nonreductive variety, ...which combines ontological physicalism with property dualism. | |
From: Jaegwon Kim (Philosophy of Mind [1996], p.212) | |
A reaction: I suspect that property dualism is actually in decline, but we will see. I have yet to find a coherent definition of property dualism. If being simultaneously red and square isn't property dualism, then what is it? Sounds like dualism to me. |
3362 | Supervenience says all souls are identical, being physically indiscernible [Kim] |
Full Idea: If one accepts the supervenience of mental on physical, this logically implies that there can only be one Cartesian soul, because such souls are physically indiscernible, and hence mentally indiscernible. | |
From: Jaegwon Kim (Philosophy of Mind [1996], p. 10) | |
A reaction: Not very persuasive. Brains are certainly discernible, and so are parts of brains. Egos might be mentally discernible. I don't find my notion of personal identity collapsing just because I espouse property dualism. |
17277 | If mind supervenes on the physical, it may also explain the physical (and not vice versa) [Fine,K] |
Full Idea: It is not enough to require that the mental should modally supervene on the physical, since that still leaves open the possibility that the physical is itself ultimately to be understood in terms of the mental. | |
From: Kit Fine (Guide to Ground [2012], 1.02) | |
A reaction: See Horgan on supervenience. Supervenience is a question, not an answer. The first question is whether the supervenience is mutual, and if not, which 'direction' does it go in? |
3413 | Zombies and inversion suggest non-reducible supervenience [Kim] |
Full Idea: The main argument for the physical supervenience of qualia, then, is the apparent conceivability of zombies and qualia inversion in organisms physically indistinguishable from us. | |
From: Jaegwon Kim (Philosophy of Mind [1996], p.171) | |
A reaction: Since neither zombies nor qualia inversion for identical brains seem to me to be even remotely conceivable, I won't trouble myself with the very vague concept of 'supervenience'. |
3374 | Token physicalism isn't reductive; it just says all mental events have some physical properties [Kim] |
Full Idea: Token physicalism (as opposed to type physicalism) is a weak doctrine which simply says that any event or occurrence with a mental property has some physical property or other. It is not committed to reductionism. | |
From: Jaegwon Kim (Philosophy of Mind [1996], p. 61) | |
A reaction: Sounds nice, but it seems incoherent to me. How can something have a physical property if it isn't physical? Try 'it isn't coloured, but has colour properties', or 'not a square, but with square properties'. 'Not divine, but divine properties' maybe. |
3433 | The core of the puzzle is the bridge laws between mind and brain [Kim] |
Full Idea: From the emergentist point of view, the reductionists bridge laws are precisely what need to be explained. Why do these mental-physical correlations hold? | |
From: Jaegwon Kim (Philosophy of Mind [1996], p.229) | |
A reaction: Everyone is happy with the bridge laws from chemistry to physics, but no one knows (deep down) why those exact laws hold. We need to understand what consciousness is; its cause will then, I think, become apparent. |
3377 | Elimination can either be by translation or by causal explanation [Kim] |
Full Idea: The two best know attempts to analyse away mental states are Armstrong's causal conception of such states (e.g. pain is a neural event caused by tissue damage), and Smart's 'topic-neutral translation'. | |
From: Jaegwon Kim (Philosophy of Mind [1996], p. 67) | |
A reaction: Armstrong's view certainly seems to be missing something, since his 'pain' could do the job without consciousness. I take Smart's approach to be the germ of the right answer. |
3438 | Reductionists deny new causal powers at the higher level [Kim] |
Full Idea: For the reductionist, no new causal powers emerge at higher levels, which goes against the claims of the emergentist and the non-reductive physicalist. | |
From: Jaegwon Kim (Philosophy of Mind [1996], p.232) | |
A reaction: I would say that all higher level causes are simply the sums of lower level causes, as in chemistry and physics. What could possibly produced the power at the higher level, apart from the constituents of the thing? Magic? |
3440 | Without reductionism, mental causation is baffling [Kim] |
Full Idea: If reductionism goes, so does the intelligibility of mental causation. | |
From: Jaegwon Kim (Philosophy of Mind [1996], p.237) | |
A reaction: Quite so. Substance dualism turns mental causation into a miracle, but property dualism is really no better. If no laws connect brain and mind, you have no account. I don't see how 'reasons are causes' (Davidson) helps at all. |
3375 | If an orange image is a brain state, are some parts of the brain orange? [Kim] |
Full Idea: If an orange visual image is a brain state then, by the indiscernibility of identicals, some brain state must also be orange. | |
From: Jaegwon Kim (Philosophy of Mind [1996], p. 64) | |
A reaction: I think this is the Hardest of all Hard Questions: how can I experience orange if my neurons haven't turned orange? What on earth is orangeness? I don't believe it is a 'microproperty' of orange objects; it's in us. |
3411 | How do we distinguish our attitudes from one another? [Kim] |
Full Idea: How do you find out that you believe, rather than, say, doubt or merely hope, that it will rain tomorrow? | |
From: Jaegwon Kim (Philosophy of Mind [1996], p.159) | |
A reaction: There should be a special medal created for philosophers who ask reasonable questions which are impossible to answer. They are among the greatest discoveries. |
3386 | Folk psychology has been remarkably durable [Kim] |
Full Idea: Commonsense psychology seems to have an advantage over scientific psychology: its apparent greater stability. Scientific theories seem to come and go. | |
From: Jaegwon Kim (Philosophy of Mind [1996], p.110) | |
A reaction: This seems to make the assumption that the folk are in universal long-term agreement about such things, which seems doubtful. See Ideas 2987 and 3410. |
3394 | Maybe folk psychology is a simulation, not a theory [Kim] |
Full Idea: There is the "theory" theory of commonsense psychology, and also a "simulation" theory, which says it is not a matter of laws, but of simulating the behaviour of others, using ourselves as models. | |
From: Jaegwon Kim (Philosophy of Mind [1996], p.123) | |
A reaction: Using ourselves as models may be the normal and correct way to relate to people within our own culture, but we have to start theorising when we encounter (e.g.) suicide bombers. |
3387 | A culture without our folk psychology would be quite baffling [Kim] |
Full Idea: A culture that lacked our folk psychology would be unintelligible to us, and its language untranslatable into our own. | |
From: Jaegwon Kim (Philosophy of Mind [1996], p.110) | |
A reaction: Surely we can manage to discuss the processing life of a robot, without having to resort to anthropomorphic psychology? Its human-style behaviour will fit, but the rest blatantly won't. |
3410 | Folk psychology has adapted to Freudianism [Kim] |
Full Idea: Freudian depth psychology has now almost achieved the status of folk psychology of the sophisticates. | |
From: Jaegwon Kim (Philosophy of Mind [1996], p.158) | |
A reaction: You don't need to be a 'sophisticate' to laugh knowingly when someone makes an embarrassing Freudian slip. Terms like 'neurotic' are commonplace among modern folk. |
3382 | A machine with a mind might still fail the Turing Test [Kim] |
Full Idea: The Turing test is too tough, because something doesn't have to be smart enough to outwit a human (or even have language) to have mentality or intelligence. | |
From: Jaegwon Kim (Philosophy of Mind [1996], p. 97) | |
A reaction: Presumably an alien with an IQ of 580 would also fail the Turing test. Indeed people of normal ability, but from a very different culture, might also fail. However, most of us would pass it. |
3383 | The Turing Test is too specifically human in its requirements [Kim] |
Full Idea: The Turing test is too narrow, because it is designed to fool a human interrogator, but there could be creatures which are intelligent but still fail the test. | |
From: Jaegwon Kim (Philosophy of Mind [1996], p. 97) | |
A reaction: I think the key test for intelligence would be a capacity for metathought. 'What do you think of the idea that x?' Their thoughts about x might be utterly stupid, of course. How do you measure 'stupid'? |
3408 | Two identical brain states could have different contents in different worlds [Kim] |
Full Idea: States that have the same intrinsic properties - the same neural/physical properties - may have different contents if they are embedded in different environments. | |
From: Jaegwon Kim (Philosophy of Mind [1996], p.146) | |
A reaction: This is a way of expressing externalism. It depends what you mean by 'contents'. I struggle to see how "H2O" could be the content of the word 'water' among ancient Greeks. |
3420 | Two types of water are irrelevant to accounts of behaviour [Kim] |
Full Idea: The difference in the two types of 'water' in the Twin Earth experiment seem psychologically irrelevant, for behaviour causation or explanation. | |
From: Jaegwon Kim (Philosophy of Mind [1996], p.203) | |
A reaction: A rather important point. No matter how externalist you are about what content really is, people can only act on the internal aspects of it. |
3416 | Content may match several things in the environment [Kim] |
Full Idea: If content is said to be 'covariance' with something in the environment, then the belief that there are horses in the field covaries reliably with the presence of horses in the field, but also the presence of horse genes in the field. | |
From: Jaegwon Kim (Philosophy of Mind [1996], p.192) | |
A reaction: That's the end of that interesting proposal, then. Or is it? Looking at the field from a distance this is right, but down the microscope, the covariance varies. The theory lives on. |
3418 | 'Arthritis in my thigh' requires a social context for its content to be meaningful [Kim] |
Full Idea: The example of someone claiming "arthritis in my thigh" shows that the content of belief depends, at least in part but crucially, on the speech practices of the linguistic community in which we situate the subject. | |
From: Jaegwon Kim (Philosophy of Mind [1996], p.197) | |
A reaction: Personally I find this social aspect to meaning to be more convincing that Putnam's idea that the physical world is part of meaning. It connects nicely with the social aspects of justification. |
3421 | Content is best thought of as truth conditions [Kim] |
Full Idea: It is standard to take contents as truth conditions. | |
From: Jaegwon Kim (Philosophy of Mind [1996], p.203) | |
A reaction: This tradition runs from Frege to Davidson, and has been extended to truth conditions in possible worlds. Rivals will involve intentions, or eliminativism about meaning. |
3419 | Pain, our own existence, and negative existentials, are not external [Kim] |
Full Idea: No external factors seem to be required for Fred's belief that he is in pain, or that he exists, or that there are no unicorns. | |
From: Jaegwon Kim (Philosophy of Mind [1996], p.198) | |
A reaction: This is an extremely important observation for anyone who was getting over-excited about external accounts of content. Unicorns might connect externally to horns and horses. |
3417 | Content depends on other content as well as the facts [Kim] |
Full Idea: An objection to the 'covariance' theory of content is that what you believe is influenced, often crucially, by what else you believe. | |
From: Jaegwon Kim (Philosophy of Mind [1996], p.193) | |
A reaction: I can't think of a reply to this, if the covariance theory is suggesting that content just IS covariance of mental states with the environment. Externalism says that mind extends into the world. |
3403 | We assume people believe the obvious logical consequences of their known beliefs [Kim] |
Full Idea: We attribute to a subject beliefs that are obvious logical consequences of beliefs already attributed to him. | |
From: Jaegwon Kim (Philosophy of Mind [1996], p.135) | |
A reaction: Depends what you mean by 'obvious'. Presumably they must be judged obvious to the believer, but only if they have thought of them. We can't believe all the simple but quirky implications of our beliefs. |
3402 | If someone says "I do and don't like x", we don't assume a contradiction [Kim] |
Full Idea: If someone says "I do and I don't like x", we do not take her to be expressing a literally contradictory belief. | |
From: Jaegwon Kim (Philosophy of Mind [1996], p.135) | |
A reaction: It might mean 'one minute I like it, and the next minute I don't', where there seems to be a real contradiction, with a time factor. You can't sustain both preferences with conviction. |
15146 | Some kinds, such as electrons, have essences, but 'cluster kinds' do not [Chakravartty] |
Full Idea: Many of the kinds we theorize about and experiment on today simply do not have essences. We can distinguish 'essence kinds', such as electrons, and 'cluster kinds', such as biological species. | |
From: Anjan Chakravarrty (Inessential Aristotle: Powers without Essences [2012], 2) | |
A reaction: This is an important point for essentialists. He offers a strict criterion, in Idea 15145, for mind membership, but we might allow species to have essences by just relaxing the criteria a bit, and acknowledging some vagueness, especially over time. |
3401 | A common view is that causal connections must be instances of a law [Kim] |
Full Idea: A widely but not universally accepted principle is that causally connected events must instantiate a law. | |
From: Jaegwon Kim (Philosophy of Mind [1996], p.133) |
15151 | Many causal laws do not refer to kinds, but only to properties [Chakravartty] |
Full Idea: Causal laws often do not make reference to kinds of objects at all, but rather summarize relations between quantitative, causally efficacious properties of objects. | |
From: Anjan Chakravarrty (Inessential Aristotle: Powers without Essences [2012], 3) | |
A reaction: This would only be a serious challenge if it was not possible to translate talk of properties into talk of kinds, and vice versa. |
3407 | Laws are either 'strict', or they involve a 'ceteris paribus' clause [Kim] |
Full Idea: Some laws are held to be 'strict', and others involve a 'ceteris paribus' clause. | |
From: Jaegwon Kim (Philosophy of Mind [1996], p.143) |
