| 19250 | Everything interesting should be recorded, with records that can be rearranged [Peirce] |
| Full Idea: Everything worth notice is worth recording; and those records should be so made that they can readily be arranged, and particularly so that they can be rearranged. | |
| From: Charles Sanders Peirce (Reasoning and the Logic of Things [1898], V) | |
| A reaction: Yet another epigraph for my project! Peirce must have had a study piled with labelled notes, and he would have adored this database, at least in its theory. |
| 19228 | Sciences concern existence, but philosophy also concerns potential existence [Peirce] |
| Full Idea: Philosophy differs from the special sciences in not confining itself to the reality of existence, but also to the reality of potential being. | |
| From: Charles Sanders Peirce (Reasoning and the Logic of Things [1898], I) | |
| A reaction: One might reply that sciences also concern potential being, if their output is universal generalisations (such as 'laws'). I take disposition and powers to be central to existence, which are hence of interest to sciences. |
| 19241 | An idea on its own isn't an idea, because they are continuous systems [Peirce] |
| Full Idea: There is no such thing as an absolutely detached idea. It would be no idea at all. For an idea is itself a continuous system. | |
| From: Charles Sanders Peirce (Reasoning and the Logic of Things [1898], III) | |
| A reaction: This is the new anti-epigraph for this database. This idea is part of Peirce's idea that relations are the central feature of our grasp of the world. |
| 19227 | Philosophy is a search for real truth [Peirce] |
| Full Idea: Philosophy differs from mathematics in being a search for real truth. | |
| From: Charles Sanders Peirce (Reasoning and the Logic of Things [1898], I) | |
| A reaction: This is important, coming from the founder of pragmatism, in rejecting the anti-realism which a lot of modern pragmatists seem to like. |
| 19218 | Metaphysics is pointless without exact modern logic [Peirce] |
| Full Idea: The metaphysician who is not prepared to grapple with the difficulties of modern exact logic had better put up his shutters and go out of the trade. | |
| From: Charles Sanders Peirce (Reasoning and the Logic of Things [1898], I) | |
| A reaction: This announcement comes before Russell proclaimed mathematical logic to be the heart of metaphysics (though it is contemporary with Frege's work, of which Peirce was unaware). It places Peirce firmly in the analytic tradition. |
| 13734 | Modern Quinean metaphysics is about what exists, but Aristotelian metaphysics asks about grounding [Schaffer,J] |
| Full Idea: On the now dominant Quinean view, metaphysics is about what there is (such as properties, meanings and numbers). I will argue for the revival of a more traditional Aristotelian view, on which metaphysics is about what grounds what. | |
| From: Jonathan Schaffer (On What Grounds What [2009], Intro) | |
| A reaction: I find that an enormously helpful distinction, and support the Aristotelian view. Schaffer's general line is that what exists is fairly uncontroversial and dull, but the interesting truths about the world emerge when we grasp its structure. |
| 13751 | If you tore the metaphysics out of philosophy, the whole enterprise would collapse [Schaffer,J] |
| Full Idea: Traditional metaphysics is so tightly woven into the fabric of philosophy that it cannot be torn out without the whole tapestry unravelling. | |
| From: Jonathan Schaffer (On What Grounds What [2009], 2.3) | |
| A reaction: I often wonder why the opponents of metaphysics still continue to do philosophy. I don't see how you address questions of ethics, or philosophy of mathematics (etc) without coming up against highly general and abstract over-questions. |
| 19229 | Metaphysics is the science of both experience, and its general laws and types [Peirce] |
| Full Idea: Metaphysics is the science of being, not merely as given in physical experience, but of being in general, its laws and types. | |
| From: Charles Sanders Peirce (Reasoning and the Logic of Things [1898], I) | |
| A reaction: I agree with this. The question then is whether such a science is possible. Dogmatic empiricists think not. Explanatory empiricists (me) think it is. |
| 19219 | Metaphysical reasoning is simple enough, but the concepts are very hard [Peirce] |
| Full Idea: Metaphysical reasonings, such as they have hitherto been, have been simple enough for the most part. It is the metaphysical concepts which it is difficult to apprehend. | |
| From: Charles Sanders Peirce (Reasoning and the Logic of Things [1898], I) | |
| A reaction: Peirce is not, of course, saying that it is just conceptual, because for him science comes first. It is the woolly concepts that alienate some people from metaphysics. Metaphysicians should challenge the concepts they use much, much more! |
| 19231 | Metaphysics is turning into logic, and logic is becoming mathematics [Peirce] |
| Full Idea: Metaphysics is gradually and surely taking on the character of a logic. And finally seems destined to become more and more converted into mathematics. | |
| From: Charles Sanders Peirce (Reasoning and the Logic of Things [1898], I) | |
| A reaction: Remarkably prescient for 1898. I don't think Peirce knew of Frege (and certainly not when he wrote this). It shows that the revolution of Frege and Russell was in the air. It's there in Dedekind's writings. Peirce doesn't seem to be a logicist. |
| 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) |
| 13743 | We should not multiply basic entities, but we can have as many derivative entities as we like [Schaffer,J] |
| Full Idea: Occam's Razor should only be understood to concern substances: do not multiply basic entities without necessity. There is no problem with the multiplication of derivative entities - they are an 'ontological free lunch'. | |
| From: Jonathan Schaffer (On What Grounds What [2009], 2.1) | |
| A reaction: The phrase 'ontological free lunch' comes from Armstrong. This is probably what Occam meant. A few extra specks of dust, or even a few more numbers (thank you, Cantor!) don't seem to challenge the principle. |
| 19247 | The one unpardonable offence in reasoning is to block the route to further truth [Peirce] |
| Full Idea: To set up a philosophy which barricades the road of further advance toward the truth is the one unpardonable offence in reasoning. | |
| From: Charles Sanders Peirce (Reasoning and the Logic of Things [1898], IV) | |
| A reaction: This is Popper's rather dubious objection to essentialism in science. Yet Popper tried to do the same thing with his account of induction. |
| 19246 | 'Holding for true' is either practical commitment, or provisional theory [Peirce] |
| Full Idea: Whether or not 'truth' has two meanings, I think 'holding for true' has two kinds. One is practical holding for true which alone is entitled to the name of Belief; the other is the acceptance of a proposition, which in pure science is always provisional. | |
| From: Charles Sanders Peirce (Reasoning and the Logic of Things [1898], IV) | |
| A reaction: The problem here seems to be that we can act on a proposition without wholly believing it, like walking across thin ice. |
| 19237 | Deduction is true when the premises facts necessarily make the conclusion fact true [Peirce] |
| Full Idea: The question of whether a deductive argument is true or not is simply the question whether or not the facts stated in the premises could be true in any sort of universe no matter what be true without the fact stated in the conclusion being true likewise. | |
| From: Charles Sanders Peirce (Reasoning and the Logic of Things [1898], III) | |
| A reaction: A remarkably modern account, fitting the normal modern view of semantic consequence, and expressing the necessity in the validity in terms of something close to possible worlds. |
| 19256 | Our research always hopes that reality embodies the logic we are employing [Peirce] |
| Full Idea: Every attempt to understand anything at least hopes that the very objects of study themselves are subject to a logic more or less identical with that which we employ. | |
| From: Charles Sanders Peirce (Reasoning and the Logic of Things [1898], VIII) | |
| A reaction: The idea that external objects might be subject to a logic has become very unfashionable since Frege, but I love the idea. I'm inclined to think that we derive our logic from the world, so I'm a bit more confident that Peirce. |
| 19238 | The logic of relatives relies on objects built of any relations (rather than on classes) [Peirce] |
| Full Idea: In the place of the class ...the logic of relatives considers the system, which is composed of objects brought together by any kind of relations whatsoever. | |
| From: Charles Sanders Peirce (Reasoning and the Logic of Things [1898], III) | |
| A reaction: Peirce's logic of relations might support the purely structural view of reality defended by Ladyman and Ross. Modern logic standardly expresses its semantics in terms of set theory. Peirce pioneered relations in logic. |
| 13741 | If 'there are red roses' implies 'there are roses', then 'there are prime numbers' implies 'there are numbers' [Schaffer,J] |
| Full Idea: We can automatically infer 'there are roses' from 'there are red roses' (with no shift in the meaning of 'roses'). Likewise one can automatically infer 'there are numbers' from 'there are prime numbers'. | |
| From: Jonathan Schaffer (On What Grounds What [2009], 2.1) | |
| A reaction: He similarly observes that the atheist's 'God is a fictional character' implies 'there are fictional characters'. Schaffer is not committing to a strong platonism with his claim - merely that the existence of numbers is hardly worth disputing. |
| 19226 | We now know that mathematics only studies hypotheses, not facts [Peirce] |
| Full Idea: It did not become clear to mathematicians before modern times that they study nothing but hypotheses without as pure mathematicians caring at all how the actual facts may be. | |
| From: Charles Sanders Peirce (Reasoning and the Logic of Things [1898], I) | |
| A reaction: 'Modern' here is 1898. As a logical principle this would seem to qualify as 'if-thenism' (see alphabetical themes). It's modern descendant might be modal structuralism (see Geoffrey Hellman). It take maths to be hypotheses abstracted from experience. |
| 13748 | Grounding is unanalysable and primitive, and is the basic structuring concept in metaphysics [Schaffer,J] |
| Full Idea: Grounding should be taken as primitive, as per the neo-Aristotelian approach. Grounding is an unanalyzable but needed notion - it is the primitive structuring conception of metaphysics. | |
| From: Jonathan Schaffer (On What Grounds What [2009], 2.2) | |
| A reaction: [he cites K.Fine 1991] I find that this simple claim clarifies the discussions of Kit Fine, where you are not always quite sure what the game is. I agree fully with it. It makes metaphysics interesting, where cataloguing entities is boring. |
| 13747 | Supervenience is just modal correlation [Schaffer,J] |
| Full Idea: Supervenience is mere modal correlation. | |
| From: Jonathan Schaffer (On What Grounds What [2009], 2.2) |
| 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. |
| 13744 | The cosmos is the only fundamental entity, from which all else exists by abstraction [Schaffer,J] |
| Full Idea: My preferred view is that there is only one fundamental entity - the whole concrete cosmos - from which all else exists by abstraction. | |
| From: Jonathan Schaffer (On What Grounds What [2009], 2.1) | |
| A reaction: This looks to me like weak anti-realism - that there are no natural 'joints' in nature - but I don't think Schaffer intends that. I take the joints to be fundamentals, which necessitates that the cosmos has parts. His 'abstraction' is clearly a process. |
| 19240 | Realism is the belief that there is something in the being of things corresponding to our reasoning [Peirce] |
| Full Idea: If there is any reality, then it consists of this: that there is in the being of things something which corresponds to the process of reasoning. | |
| From: Charles Sanders Peirce (Reasoning and the Logic of Things [1898], III) | |
| A reaction: A nice definition of realism, a little different from usual. I belief that the normal logic of daily thought corresponds (in its rules and connectives) to the way the world is. We evaluate success in logic by truth-preservation. |
| 19239 | There may be no reality; it's just our one desperate hope of knowing anything [Peirce] |
| Full Idea: What is reality? Perhaps there isn't any such thing at all. It is but a working hypothesis which we try, our one desperate forlorn hope of knowing anything. | |
| From: Charles Sanders Peirce (Reasoning and the Logic of Things [1898], III) | |
| A reaction: I'm not quite sure why the hope is 'forlorn'. We have no current reason to doubt that the hypothesis is working out extremely well. Lovely idea, though. |
| 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. |
| 13739 | Maybe categories are just the different ways that things depend on basic substances [Schaffer,J] |
| Full Idea: Maybe the categories are determined by the different grounding relations, ..so that categories just are the ways things depend on substances. ...Categories are places in the dependence ordering. | |
| From: Jonathan Schaffer (On What Grounds What [2009], 1.3) |
| 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? |
| 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) |
| 13742 | There exist heaps with no integral unity, so we should accept arbitrary composites in the same way [Schaffer,J] |
| Full Idea: I am happy to accept universal composition, on the grounds that there are heaps, piles etc with no integral unity, and that arbitrary composites are no less unified than heaps. | |
| From: Jonathan Schaffer (On What Grounds What [2009], 2.1 n11) | |
| A reaction: The metaphysical focus is then placed on what constitutes 'integral unity', which is precisely the question which most interested Aristotle. Clearly if there is nothing more to an entity than its components, scattering them isn't destruction. |
| 13752 | The notion of 'grounding' can explain integrated wholes in a way that mere aggregates can't [Schaffer,J] |
| Full Idea: The notion of grounding my capture a crucial mereological distinction (missing from classical mereology) between an integrated whole with genuine unity, and a mere aggregate. x is an integrated whole if it grounds its proper parts. | |
| From: Jonathan Schaffer (On What Grounds What [2009], 3.1) | |
| A reaction: That gives a nice theoretical notion, but if you remove each of the proper parts, does x remain? Is it a bare particular? I take it that it will have to be an abstract principle, the one Aristotle was aiming at with his notion of 'form'. Schaffer agrees. |
| 19252 | Objective chance is the property of a distribution [Peirce] |
| Full Idea: Chance, as an objective phenomenon, is a property of a distribution. ...In order to have any meaning, it must refer to some definite arrangement of all the things. | |
| From: Charles Sanders Peirce (Reasoning and the Logic of Things [1898], VI) |
| 19232 | In ordinary language a conditional statement assumes that the antecedent is true [Peirce] |
| Full Idea: In our ordinary use of language we always understand the range of possibility in such a sense that in some possible case the antecedent shall be true. | |
| From: Charles Sanders Peirce (Reasoning and the Logic of Things [1898], II) | |
| A reaction: Peirce is discussing Diodorus, and proposes the view nowadays defended by Edgington, though in the end Peirce defends the standard material conditional as simpler. I suspect that this discussion by Peirce is not well known. |
| 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) |
| 13749 | Belief in impossible worlds may require dialetheism [Schaffer,J] |
| Full Idea: One motivation for dialetheism is the view that there are impossible worlds. | |
| From: Jonathan Schaffer (On What Grounds What [2009], 2.3) |
| 19223 | We act on 'full belief' in a crisis, but 'opinion' only operates for trivial actions [Peirce] |
| Full Idea: 'Full belief' is willingness to upon a proposition in vital crises, 'opinion' is willingness to act on it in relatively insignificant affairs. But pure science has nothing at all to do with action. | |
| From: Charles Sanders Peirce (Reasoning and the Logic of Things [1898], I) | |
| A reaction: A nice clear statement of the pragmatic view of beliefs. It is not much help in distinguishing full belief about the solar system from mere opinion about remote galaxies. Ditto for historical events. |
| 13740 | 'Moorean certainties' are more credible than any sceptical argument [Schaffer,J] |
| Full Idea: A 'Moorean certainty' is when something is more credible than any philosopher's argument to the contrary. | |
| From: Jonathan Schaffer (On What Grounds What [2009], 2.1) | |
| A reaction: The reference is to G.E. Moore's famous claim that the existence of his hand is more certain than standard sceptical arguments. It sounds empiricist, but they might be parallel rational truths, of basic logic or arithmetic. |
| 19253 | We talk of 'association by resemblance' but that is wrong: the association constitutes the resemblance [Peirce] |
| Full Idea: Allying certain ideas like 'crimson' and 'scarlet' is called 'association by resemblance'. The name is not a good one, since it implies that resemblance causes association, while in point of fact it is the association which constitutes the resemblance. | |
| From: Charles Sanders Peirce (Reasoning and the Logic of Things [1898], VII) | |
| A reaction: I take it that Hume would have agreed with this. It is an answer to Russell's claim that 'resemblance' must itself be a universal. |
| 19224 | Scientists will give up any conclusion, if experience opposes it [Peirce] |
| Full Idea: The scientific man is not in the least wedded to his conclusions. He risks nothing upon them. He stands ready to abandon one or all as experience opposes them. | |
| From: Charles Sanders Peirce (Reasoning and the Logic of Things [1898], I) | |
| A reaction: In the age of massive speculative research grants, the idea that 'he risks nothing upon them' is no longer true. Ditto for building aircraft and bridges, which are full of theoretical science. Notoriously, many scientists don't live up to Peirce's idea. |
| 19243 | If each inference slightly reduced our certainty, science would soon be in trouble [Peirce] |
| Full Idea: Were every probable inference less certain than its premises, science, which piles inference upon inference, often quite deeply, would soon be in a bad way. | |
| From: Charles Sanders Peirce (Reasoning and the Logic of Things [1898], IV) | |
| A reaction: This seems to endorse Aristotle's picture of demonstration about scientific and practical things as being a form of precise logic, rather than progressive probabilities. Our generalisations may be more certain than the particulars they rely on. |
| 19225 | I classify science by level of abstraction; principles derive from above, and data from below [Peirce] |
| Full Idea: I classify the sciences on Comte's general principles, in order of the abstractness of their objects, so that each science may largely rest for its principles upon those above it in the scale, while drawing its data in part from those below it. | |
| From: Charles Sanders Peirce (Reasoning and the Logic of Things [1898], I) | |
| A reaction: He places mathematics at the peak of abstraction. I assume physics is more abstract than biology. So chemistry draws principles from physics and data from biology. Not sure about this. Probably need to read Comte on it. |
| 19234 | 'Induction' doesn't capture Greek 'epagoge', which is singulars in a mass producing the general [Peirce] |
| Full Idea: The word 'inductio' is Cicero's imitation of Aristotle's term 'epagoge'. It fails to convey the full significance of the Greek word, which implies the examples are arrayed and brought forward in a mass. 'The assault upon the generals by the singulars'. | |
| From: Charles Sanders Peirce (Reasoning and the Logic of Things [1898], II) | |
| A reaction: Interesting, thought I don't think there is enough evidence in Aristotle to get the Greek idea fully clear. |
| 19235 | How does induction get started? [Peirce] |
| Full Idea: Induction can never make a first suggestion. | |
| From: Charles Sanders Peirce (Reasoning and the Logic of Things [1898], II) | |
| A reaction: This seems to lead to the general modern problem of the 'theory-laden' nature of observation. You don't see anything at all without some idea of what you are looking for. How do you spot the 'next instance'. Instance of what? Nice. |
| 19236 | Induction can never prove that laws have no exceptions [Peirce] |
| Full Idea: Induction can never afford the slightest reason to think that a law is without an exception. | |
| From: Charles Sanders Peirce (Reasoning and the Logic of Things [1898], II) | |
| A reaction: Part of the general Humean doubts about induction, but very precisely stated, and undeniable. You can then give up on universal laws, or look for deeper reasons to justify your conviction that there are no exceptions. E.g. observe mass, or Higgs Boson. |
| 19251 | The worst fallacy in induction is generalising one recondite property from a sample [Peirce] |
| Full Idea: The most dangerous fallacy of inductive reasoning consists in examining a sample, finding some recondite property in it, and concluding at once that it belongs to the whole collection. | |
| From: Charles Sanders Peirce (Reasoning and the Logic of Things [1898], V) | |
| A reaction: The point, I take it, is not that you infer that the whole collection has all the properties of the sample, but that some 'recondite' or unusual property is sufficiently unusual to be treated as general. |
| 19222 | Men often answer inner 'whys' by treating unconscious instincts as if they were reasons [Peirce] |
| Full Idea: Men many times fancy that they act from reason, when the reasons they attribute to themselves are nothing but excuses which unconscious instinct invents to satisfy the teasing 'whys' of the ego. | |
| From: Charles Sanders Peirce (Reasoning and the Logic of Things [1898], I) | |
| A reaction: A strikely modern thought, supported by a lot of modern neuro-science and psychology. It is crucial to realise that we don't have to accept the best explanation we can think of. |
| 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. |
| 19220 | We may think animals reason very little, but they hardly ever make mistakes! [Peirce] |
| Full Idea: Those whom we are so fond of referring to as the 'lower animals' reason very little. Now I beg you to observe that those beings very rarely commit a mistake, while we ---- ! | |
| From: Charles Sanders Peirce (Reasoning and the Logic of Things [1898], I) | |
| A reaction: We might take this as pessimism about reason, but I would take it as inviting a much broader view of rationality. I think nearly all animal behaviour is highly rational. Are animals 'sensible' in what they do? Their rationality is unadventurous. |
| 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. |
| 19255 | Generalisation is the great law of mind [Peirce] |
| Full Idea: The generalising tendency is the great law of mind. | |
| From: Charles Sanders Peirce (Reasoning and the Logic of Things [1898], VII) | |
| A reaction: How else could a small and compact mind get a grip on a vast and diverse reality? This must even apply to inarticulate higher animals. |
| 19242 | Generalization is the true end of life [Peirce] |
| Full Idea: Generalization, the spelling out of continuous systems, in thought, in sentiment, in deed, is the true end of life. | |
| From: Charles Sanders Peirce (Reasoning and the Logic of Things [1898], III) | |
| A reaction: I take understanding to be the true aim of life, and full grasp of particulars (e.g. of particular people) is as necessary as generalisation. This is still a very nice bold idea. |
| 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. |
| 19249 | 'Know yourself' is not introspection; it is grasping how others see you [Peirce] |
| Full Idea: 'Know thyself' does not mean instrospect your soul. It means see yourself as others would see you if they were intimate enough with you. | |
| From: Charles Sanders Peirce (Reasoning and the Logic of Things [1898], V) | |
| A reaction: When it comes to anger management, I would have thought that introspection had some use. You can see a tantrum coming before even your intimates can. Nice disagreement with Sartre! (Idea 7123) |
| 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. |
| 19257 | Whatever is First must be sentient [Peirce] |
| Full Idea: I think that what is First is ipso facto sentient. | |
| From: Charles Sanders Peirce (Reasoning and the Logic of Things [1898], VIII) | |
| A reaction: He doesn't mention Leibniz's monads, but that looks like the ancestor of Peirce's idea. He doesn't make clear (here) how far he would take the idea. I would just say that whatever is 'First' must be active rather than passive. |
| 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. |
| 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. |
| 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? |
| 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. |
| 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. |
| 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. |
| 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. |
| 19248 | Reasoning involves observation, experiment, and habituation [Peirce] |
| Full Idea: The mental operations concerning in reasoning are three. The first is Observation; the second is Experimentation; and the third is Habituation. | |
| From: Charles Sanders Peirce (Reasoning and the Logic of Things [1898], V) | |
| A reaction: I like the breadth of this. Even those who think scientific reasoning has priority over logic (as I do, thinking of it as the evaluation of evidence, with Sherlock Holmes as its role model) will be surprised to finding observation and habituation there. |
| 19221 | Everybody overrates their own reasoning, so it is clearly superficial [Peirce] |
| Full Idea: The very fact that everybody so ridiculously overrates his own reasoning, is sufficient to show how superficial the faculty is. | |
| From: Charles Sanders Peirce (Reasoning and the Logic of Things [1898], I) | |
| A reaction: A nice remark. The obvious counter-thought is that the collective reasoning of mankind really has been rather impressive, even though people haven't yet figured out how to live at peace with one another. |
| 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. |
| 19233 | Indexicals are unusual words, because they stimulate the hearer to look around [Peirce] |
| Full Idea: Words like 'this', 'that', 'I', 'you', enable us to convey meanings which words alone are incompetent to express; they stimulate the hearer to look about him. | |
| From: Charles Sanders Peirce (Reasoning and the Logic of Things [1898], II) | |
| A reaction: Peirce was once of the first to notice the interest of indexicals, and this is a very nice comment on them. A word like 'Look!' isn't like the normal flow of verbiage, and may be the key to indexicals. |
| 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. |
| 19230 | People should follow what lies before them, and is within their power [Peirce] |
| Full Idea: Each person ought to select some definite duty that clearly lies before him and is well within his power as the special task of his life. | |
| From: Charles Sanders Peirce (Reasoning and the Logic of Things [1898], I) | |
| A reaction: I like that. Note especially that it should be 'well' within his power. Note also that this is a 'duty', and not just a friendly suggestion. Not sure what the basis of the duty is. |
| 19245 | We are not inspired by other people's knowledge; a sense of our ignorance motivates study [Peirce] |
| Full Idea: It is not the man who thinks he knows it all, that can bring other men to feel their need for learning, and it is only a deep sense that one is miserably ignorant that can spur one on in the toilsome path of learning. | |
| From: Charles Sanders Peirce (Reasoning and the Logic of Things [1898], IV) |
| 19244 | Chemists rely on a single experiment to establish a fact; repetition is pointless [Peirce] |
| Full Idea: The chemist contents himself with a single experiment to establish any qualitative fact, because he knows there is such a uniformity in the behavior of chemical bodies that another experiment would be a mere repetition of the first in every respect. | |
| From: Charles Sanders Peirce (Reasoning and the Logic of Things [1898], IV) | |
| A reaction: I take it this endorses my 'Upanishads' view of natural kinds - that for each strict natural kind, if you've seen one you've them all. This seems to fit atoms and molecules, but only roughly fits tigers. |
| 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) |
| 19254 | Our laws of nature may be the result of evolution [Peirce] |
| Full Idea: We may suppose that the laws of nature are results of an evolutionary process. ...But this evolution must proceed according to some principle: and this principle will itself be of the nature of a law. | |
