| 22611 | Metaphysics can criticise interpretations of science theories, and give good feedback [Ingthorsson] |
| Full Idea: Metaphysics is capable of critical scrutiny of the way the empirical sciences make sense of their own theories, and can provide them with very useful feedback. | |
| From: R.D. Ingthorsson (A Powerful Particulars View of Causation [2021], 1.9) | |
| A reaction: I agree with this, but I don't think it is the main job of metaphysics, which has its own agenda, using science as some of its raw material. |
| 8893 | For any given area, there seem to be a huge number of possible coherent systems of beliefs [Bonjour] |
| Full Idea: The 2nd standard objection to coherence is 'alternative coherent systems' - that there will be indefinitely many possible systems of belief in relation to any given subject area, each as internally coherent as the others. | |
| From: Laurence Bonjour (A Version of Internalist Foundationalism [2003], 3.2) | |
| A reaction: This seems to imply that you could just invent an explanation, as long as it was coherent, but presumably good coherence is highly sensitive to the actual evidence. Bonjour observes that many of these systems would not survive over time. |
| 11211 | If a sound conclusion comes from two errors that cancel out, the path of the argument must matter [Rumfitt] |
| Full Idea: If a designated conclusion follows from the premisses, but the argument involves two howlers which cancel each other out, then the moral is that the path an argument takes from premisses to conclusion does matter to its logical evaluation. | |
| From: Ian Rumfitt ("Yes" and "No" [2000], II) | |
| A reaction: The drift of this is that our view of logic should be a little closer to the reasoning of ordinary language, and we should rely a little less on purely formal accounts. |
| 22609 | Philosophers accepted first-order logic, because they took science to be descriptive, not explanatory [Ingthorsson] |
| Full Idea: First-order predicate logic was accepted so easily by the philosophical community …because philosophy was already geared toward a neo-Humean view of both science and philosophy as primarily descriptive rather than explanatory. | |
| From: R.D. Ingthorsson (A Powerful Particulars View of Causation [2021], 1.8) | |
| A reaction: The point, I think, is that explanatory thinking needs second-order logic, where the properties (or powers) are players in the game, and not just adjuncts of the catalogue of objects. I find this idea mind-expanding. (That's a good thing). |
| 11210 | Standardly 'and' and 'but' are held to have the same sense by having the same truth table [Rumfitt] |
| Full Idea: If 'and' and 'but' really are alike in sense, in what might that likeness consist? Some philosophers of classical logic will reply that they share a sense by virtue of sharing a truth table. | |
| From: Ian Rumfitt ("Yes" and "No" [2000]) | |
| A reaction: This is the standard view which Rumfitt sets out to challenge. |
| 11212 | The sense of a connective comes from primitively obvious rules of inference [Rumfitt] |
| Full Idea: A connective will possess the sense that it has by virtue of its competent users' finding certain rules of inference involving it to be primitively obvious. | |
| From: Ian Rumfitt ("Yes" and "No" [2000], III) | |
| A reaction: Rumfitt cites Peacocke as endorsing this view, which characterises the logical connectives by their rules of usage rather than by their pure semantic value. |
| 22629 | Basic processes are said to be either physical, or organic, or psychological [Ingthorsson] |
| Full Idea: Process philosophy is considered to include ideas of process as basically physical (Whitehead 1929), as basically organic (Bergson 1910), and as basically psychological (James 1890). | |
| From: R.D. Ingthorsson (A Powerful Particulars View of Causation [2021], 7.4) | |
| A reaction: I take Whitehead to be the only serious contender here. |
| 22633 | Indirect realists are cautious about the manifest image, and prefer the scientific image [Ingthorsson] |
| Full Idea: The indirect realist regards the manifest image with scepticism and contrasts it to the scientific image. | |
| From: R.D. Ingthorsson (A Powerful Particulars View of Causation [2021], 8.13) | |
| A reaction: This is why indirect realism is the best view for a realist who largely accepts the authority of science, Philosophers can wallow in the manifest image all they like (and most of them seem to love it), but truth is in the scientific image. |
| 22606 | Neo-Humeans say there are no substantial connections between anything [Ingthorsson] |
| Full Idea: Neo-Humean metaphysics holds the view that there are no substantial connections between anything in this world. | |
| From: R.D. Ingthorsson (A Powerful Particulars View of Causation [2021], 1) | |
| A reaction: A very illuminating comment. This exactly fits Lewis's great 'mosaic' of facts. The challenge is to say what 'substantial' relations there might be, but I'm quite happy to have a go at that. |
| 22631 | Properties are said to be categorical qualities or non-qualitative dispositions [Ingthorsson] |
| Full Idea: It is said that that properties divide into two mutually exclusive types—non-dispositional qualities (sometimes called 'categorical properties’) vs. non-qualitative dispositions—of which the qualities are more fundamental than dispositions. | |
| From: R.D. Ingthorsson (A Powerful Particulars View of Causation [2021], 8) | |
| A reaction: It is standardly understood that the qualitative categorical properties are more fundamental. Fans of powers (such as Ingthorsson and myself) either favour the dispositional properties, or reject the distinction. |
| 22632 | Physics understands the charge of an electron as a power, not as a quality [Ingthorsson] |
| Full Idea: Is the negative charge of an electron a quality or power? It is clear that physics describes the nature of charge only in terms of what its bearer can do. | |
| From: R.D. Ingthorsson (A Powerful Particulars View of Causation [2021], 8.06) | |
| A reaction: The point is that an electron has properties, even though it has no observable qualities. Ingthorsson says the scientific concept of qualities is entirely about what something can do, and ot how it is perceived. |
| 22627 | Compound objects are processes, insofar as change is essential to them [Ingthorsson] |
| Full Idea: Compound objects are to be considered processes, if by ‘process’ we mean any entity for which change is essential for its continued existence. | |
| From: R.D. Ingthorsson (A Powerful Particulars View of Causation [2021], 7) | |
| A reaction: This doesn't seem to matter much, except to challenge those who say that reality consists of processes, and therefore not of substances. |
| 22613 | Most materialist views postulate smallest indivisible components which are permanent [Ingthorsson] |
| Full Idea: Most materialist ontologies of the past postulate that the world ultimately consists of smallest indivisible component parts that persist because they must; they are permanent. | |
| From: R.D. Ingthorsson (A Powerful Particulars View of Causation [2021], 2.1) | |
| A reaction: Van Inwagen is notable for this view. Ingthorsson says the theory is to explain medium-sized change, while denying that anything comes to be out of nothing. Theology may lurk in the background. Simple persistance won't explain compound persistance. |
| 22612 | Endurance and perdurance just show the consequences of A or B series time [Ingthorsson] |
| Full Idea: Endurance and perdurance are not explanations, but are merely characterisations of persistance with the constraints imposed by either an A or a B view of time. | |
| From: R.D. Ingthorsson (A Powerful Particulars View of Causation [2021], 2.1) | |
| A reaction: This is 3-D asnd 4-D objects. A simple and illuminating observation. I love reading broad brush books that make all these simple connections between what seem isolated theories in philosophy. These links are the heart of the subject. |
| 22625 | Science suggests causal aspects of the constitution and persistance of objects [Ingthorsson] |
| Full Idea: There are very obvious causal aspects to the constitution and continued existence of compound entities, especially in light of the scientific image of the world. | |
| From: R.D. Ingthorsson (A Powerful Particulars View of Causation [2021], 6) | |
| A reaction: I like this a lot. He aims to explain constitution and persistance, rather than just describing or characterising them, and causal binding seems the obvious thought. There are still intermittent and distributed objects, like a dismantled clock. |
| 22620 | If causation involves production, that needs persisting objects [Ingthorsson] |
| Full Idea: If causation involves production, then things must endure rather than perdure, because perdurance is incompatible with production, if creation ex nihilo is ruled out. | |
| From: R.D. Ingthorsson (A Powerful Particulars View of Causation [2021], 4.10) | |
| A reaction: That is, objects must persist over time. Cannot an account of production be given in terms of time-sliceS (or whatever)? 3-D perdurantists obviously have an account of change. He says it also needs the A-series view of time. |
| 22636 | Every philosophical theory must be true in some possible world, so the ontology is hopeless [Ingthorsson] |
| Full Idea: Possible worlds ontology appears to be plentiful enough to allow every philosophical theory to be true in some world or other, and that is why I cannot consider it an ontologically serious theory. It admits everything and forbids nothing | |
| From: R.D. Ingthorsson (A Powerful Particulars View of Causation [2021], 9.6) | |
| A reaction: Nice. Be careful what you wish for. The theory would have to be consistent (unless we also accept impossible worlds). |
| 22638 | Worlds may differ in various respects, but no overall similarity of worlds is implied [Ingthorsson] |
| Full Idea: Even if possible worlds could differ in many different respects, there is no useful way to combine these different respects into one measure of overall comparative similarity. | |
| From: R.D. Ingthorsson (A Powerful Particulars View of Causation [2021], 9.7) | |
| A reaction: [idea of Michael Moreau 2010] This is an objection to the use of 'close' possible worlds in causation theories. The idea is true in general of the concept of similarity. It makes sense of specific 'respects', but not really of two whole objects. |
| 8888 | The concept of knowledge is so confused that it is best avoided [Bonjour] |
| Full Idea: The concept of knowledge is seriously problematic in more than one way, and is best avoided as far as possible in sober epistemological discussion. | |
| From: Laurence Bonjour (A Version of Internalist Foundationalism [2003], 1.5) | |
| A reaction: Two sorts of states seem to be conflated: one where an animal has a true belief caused by an environmental event, and the other where a scholar pores over books and experiments to arrive at a hard-won truth. I say only the second is 'knowledge'. |
| 8887 | It is hard to give the concept of 'self-evident' a clear and defensible characterization [Bonjour] |
| Full Idea: Foundationalists find it difficult to attach a clear and defensible content to the idea that basic beliefs that are characterized as 'self-justified' or 'self-evident'. | |
| From: Laurence Bonjour (A Version of Internalist Foundationalism [2003], 1.4) | |
| A reaction: A little surprising from a fan of a priori foundations, especially given that 'self-evident' is common usage, and not just philosophers' jargon. I think we can talk of self-evidence without a precise definition. We talk of an 'ocean' without trouble. |
| 8897 | The adverbial account will still be needed when a mind apprehends its sense-data [Bonjour] |
| Full Idea: The adverbial account of the content of experience is almost certainly correct, because no account can be given of the relation between sense-data and the apprehending mind that is independent of the adverbial theory. | |
| From: Laurence Bonjour (A Version of Internalist Foundationalism [2003], 5.1 n3) | |
| A reaction: This boils down to the usual objection to sense-data, which is 'cut out the middle man'. Bonjour is right that at some point the mind has finally to experience whatever is coming in, and it must experience it in a particular way. |
| 8896 | Conscious states have built-in awareness of content, so we know if a conceptual description of it is correct [Bonjour] |
| Full Idea: If we describe a non-conceptual conscious state, we are aware of its character via the constitutive or 'built-in' awareness of content without need for a conceptual description, and so recognise that a conceptually formulated belief about it is correct. | |
| From: Laurence Bonjour (A Version of Internalist Foundationalism [2003], 4.3) | |
| A reaction: This is Bonjour working very hard to find an account of primitive sense experiences which will enable them to function as 'basic beliefs' for foundations, without being too thin to do anything, or too thick to be basic. I'm not convinced. |
| 8891 | My incoherent beliefs about art should not undermine my very coherent beliefs about physics [Bonjour] |
| Full Idea: If coherentism is construed as involving the believer's entire body of beliefs, that would imply, most implausibly, that the justification of a belief in one area (physics) could be undermined by serious incoherence in another area (art history). | |
| From: Laurence Bonjour (A Version of Internalist Foundationalism [2003], 3.1) | |
| A reaction: Bonjour suggests that a moderated coherentism is needed to avoid this rather serious problem. It is hard to see how a precise specification could be given of 'areas' and 'local coherence'. An idiot about art would inspire little confidence on physics. |
| 8892 | Coherence seems to justify empirical beliefs about externals when there is no external input [Bonjour] |
| Full Idea: The 1st standard objection to coherence is the 'isolation problem', that contingent apparently-empirical beliefs might be justified in the absence of any informational input from the extra-conceptual world they attempt to describe. | |
| From: Laurence Bonjour (A Version of Internalist Foundationalism [2003], 3.2) | |
| A reaction: False beliefs can be well justified. In a perfect virtual reality we would believe our experiences precisely because they were so coherent. Messengers from the front line have top priority, but how do you detect infiltrators and liars? |
| 8894 | Coherentists must give a reason why coherent justification is likely to lead to the truth [Bonjour] |
| Full Idea: The 3rd standard objection to coherence is the demand for a meta-justification for coherence, a reason for thinking that justification on the basis of the coherentist view of justification is in fact likely to lead to believing the truth. | |
| From: Laurence Bonjour (A Version of Internalist Foundationalism [2003], 3.2) | |
| A reaction: Some coherentists respond by adopting a coherence theory of truth, which strikes me as extremely unwise. There must be an underlying optimistic view, centred on the principle of sufficient reason, that reality itself is coherent. I like Idea 8618. |
| 8889 | Reliabilists disagree over whether some further requirement is needed to produce knowledge [Bonjour] |
| Full Idea: Reliabilist views differ among themselves with regard to whether a belief's being produced in a reliable way is by itself sufficient for epistemic justification or whether there are further requirements that must be satisfied as well. | |
| From: Laurence Bonjour (A Version of Internalist Foundationalism [2003], 2.1) | |
| A reaction: If 'further requirements' are needed, the crucial question would be which one is trumps when they clash. If the further requirements can correct the reliable source, then it cannot any longer be called 'reliabilism'. It's Further-requirement-ism. |
| 8890 | If the reliable facts producing a belief are unknown to me, my belief is not rational or responsible [Bonjour] |
| Full Idea: How can the fact that a belief is reliably produced make my acceptance of that belief rational and responsible when that fact itself is entirely unavailable to me? | |
| From: Laurence Bonjour (A Version of Internalist Foundationalism [2003], 2.2) | |
| A reaction: This question must rival Pollock's proposal (Idea 8815) as the master argument against externalism. Bonjour is assuming that knowledge has to be 'rational and responsible', but clearly externalists take a more lax view of knowledge. |
| 8895 | If neither the first-level nor the second-level is itself conscious, there seems to be no consciousness present [Bonjour] |
| Full Idea: In the higher-order thought theory of consciousness, if the first-order thought is not itself conscious and the second-order thought is not itself conscious, then there seems to be no consciousness of the first-level content present at all. | |
| From: Laurence Bonjour (A Version of Internalist Foundationalism [2003], 4.2) | |
| A reaction: A nice basic question. The only plausible answer seems to be that consciousness arises out of the combination of levels. Otherwise one of the levels is redundant, or we are facing a regress. |
| 11214 | We learn 'not' along with affirmation, by learning to either affirm or deny a sentence [Rumfitt] |
| Full Idea: The standard view is that affirming not-A is more complex than affirming the atomic sentence A itself, with the latter determining its sense. But we could learn 'not' directly, by learning at once how to either affirm A or reject A. | |
| From: Ian Rumfitt ("Yes" and "No" [2000], IV) | |
| A reaction: [compressed] This seems fairly anti-Fregean in spirit, because it looks at the psychology of how we learn 'not' as a way of clarifying what we mean by it, rather than just looking at its logical behaviour (and thus giving it a secondary role). |
| 22605 | Humeans describe the surface of causation, while powers accounts aim at deeper explanations [Ingthorsson] |
| Full Idea: Humeans attempt to describe causation without any deeper ontological commitments, while powers based accounts attempt to explain why causation occurs in the way it is described. | |
| From: R.D. Ingthorsson (A Powerful Particulars View of Causation [2021], 1) | |
| A reaction: Exactly the view I have reached. The Humean view is correct but superficial. A perfect example of my allegiance to Explanatory Empiricism. |
| 22607 | Time and space are not causal, but they determine natural phenomena [Ingthorsson] |
| Full Idea: Time and space are significant determinants of natural phenomena, and yet are not (typically) regarded as causal determinants | |
| From: R.D. Ingthorsson (A Powerful Particulars View of Causation [2021], 1.4) | |
| A reaction: I like the word 'determinants'. Metaphysics largely concerns what determines what. I'm struggling to think of examples of this (which he does not give). Decay takes time, but isn't determined by time. Is a light cone a determinant? |
| 22608 | Casuation is the transmission of conserved quantities between causal processes [Ingthorsson] |
| Full Idea: Causal process theories state that causation needs to be understood in terms of causal processes and their interactions, in which conserved quantities are transmitted between causal processes. | |
| From: R.D. Ingthorsson (A Powerful Particulars View of Causation [2021], 1.5) | |
| A reaction: Sounds a bit circular, but the idea of transmission of something is obviously the main point. I like this idea a lot (because it is so naturalistic), but rarely find it taken seriously. Energy is usually the quantity picked out. |
| 22621 | Causation as transfer only works for asymmetric interactions [Ingthorsson] |
| Full Idea: The transference model of causation only works for asymmetric interactions. | |
| From: R.D. Ingthorsson (A Powerful Particulars View of Causation [2021], 4.11) | |
| A reaction: This is usually the transfer of energy. I liked the theory until I read this. |
| 22614 | Interventionist causal theory says it gets a reliable result whenever you manipulate it [Ingthorsson] |
| Full Idea: The core of agency and interventionist theories of causation is that c counts as the cause of e iff E reliably appears and disappears when you manipulate C. | |
| From: R.D. Ingthorsson (A Powerful Particulars View of Causation [2021], 2.1) | |
| A reaction: [C is the type of c; E is the type of e] James Woodward champions this view. Ingthorsson objects that the theory offers no explanation of the appearances and disappearances. You can't manipulate black holes… |
| 22639 | Causal events are always reciprocal, and there is no distinction of action and reaction [Ingthorsson] |
| Full Idea: I accept the reciprocity of interactions, and abandon the Agent vs.Patient distinction, so we can no longer talk of the contribution of each as ontologically different types of cause. In interactions, neither action nor reaction can be separated. | |
| From: R.D. Ingthorsson (A Powerful Particulars View of Causation [2021], 10.3) | |
| A reaction: His point is that we are misled by real world happenings, where one component is usually more powerful than the other (such as ball dropped onto a pillow). Modern science endorses his view. Mumford and Anjum seem to agree, and so do I. |
| 22615 | One effect cannot act on a second effect in causation, because the second doesn't yet exist [Ingthorsson] |
| Full Idea: Hobbes implies that a Kim-style event e1 existing at t1 cannot possibly act on an effect e2 at t2, because that effect does not exist until the Agent has worked its effect on the Patient to provoke a change, thus bringing the effect into existence. | |
| From: R.D. Ingthorsson (A Powerful Particulars View of Causation [2021], 3.08) | |
| A reaction: [Hobbes Elements of Phil 1656 II.IX.1] Ingthorsson says that the Hobbes view is the traditional 'standard' view, that objects (and not events) are the causal relata. A strong objection to events as the causal relata. Realists need objects. |
| 22616 | Empiricists preferred events to objects as the relata, because they have observable motions [Ingthorsson] |
| Full Idea: It is the empiricists' refusal to deal with anything other than observable events that motivated the shift in conception of efficient causation …to influence by an event on another event (one motion on another) rather than by an object on an object. | |
| From: R.D. Ingthorsson (A Powerful Particulars View of Causation [2021], 3.10) | |
| A reaction: I suppose events supply the necessary activity, whereas objects seem to be too passive for the job - because that's how they look. Ingthorsson persuades that objects are the correct causal relata, for those of us who believe in powers. |
| 22617 | Science now says all actions are reciprocal, not unidirectional [Ingthorsson] |
| Full Idea: It is now accepted as a fact of modern science that unidirectional actions do not exist, and that all interactions are instead thoroughly reciprocal. | |
| From: R.D. Ingthorsson (A Powerful Particulars View of Causation [2021], 3.10) | |
| A reaction: Ingthorsson says this undermines the standard traditional view (Hobbes etc) of Agent and Patient, with A having active powers and P having passive powers. All influences are mutual, it seems. Passive powers are active structures? |
| 22619 | Causes are not agents; the whole interaction is the cause, and the changed compound is the effect [Ingthorsson] |
| Full Idea: By abandoning the standard view that causes are ‘extrinsic motive Agents’, an idea from pre-Newtonian physics, we are free to conceive of the interaction as a whole as the cause, and the change in the compound whole of interacting things as the effect. | |
| From: R.D. Ingthorsson (A Powerful Particulars View of Causation [2021], 4.06) | |
| A reaction: Ingthorsson persuasively presents this as the correct account, as understood by modern science. It is not cause-then-effect. It is kerfuffle, then aftermath. |
| 22635 | People only accept the counterfactual when they know the underlying cause [Ingthorsson] |
| Full Idea: I doubt that anyone will accept any counterfactual as true unless they believe they know the underlying causality. | |
| From: R.D. Ingthorsson (A Powerful Particulars View of Causation [2021], 9.3) | |
| A reaction: Correct. Almost any example will support it. Compare coincidences and true causes. |
| 22634 | Counterfactuals don't explain causation, but causation can explain counterfactuals [Ingthorsson] |
| Full Idea: I cannot identify any prima facie reason to think that causation can be explained in counterfactual terms, but plenty to think that causation can explain counterfactuals. | |
| From: R.D. Ingthorsson (A Powerful Particulars View of Causation [2021], 9.1) | |
| A reaction: Love it. Treating causation as counterfactual dependency is hopelessly superficial. What is the reality that is involved? He cites the second law of motion. |
| 22637 | Counterfactual theories are false in possible worlds where causation is actual [Ingthorsson] |
| Full Idea: if there are worlds where there are causal powers and/or lawful connections, then they are worlds in which the counterfactual theory of causation is false, because there causes produce the effects, regardless of any possible world. | |
| From: R.D. Ingthorsson (A Powerful Particulars View of Causation [2021], 9.6) | |
| A reaction: A nice modern instance of turning the tables. Come to think of it, possible worlds theories are just asking for that. Are there possible worlds in which there are no other possible worlds? Or the possible worlds are inaccessible? |
| 22624 | A cause can fail to produce its normal effect, by prevention, pre-emption, finks or antidotes [Ingthorsson] |
| Full Idea: Counterexamples involving prevention and/or interference have come to be roughly divided into four main categories: (i) prevention, (ii) pre-emption, (iii) finks and (iv) antidotes. | |
| From: R.D. Ingthorsson (A Powerful Particulars View of Causation [2021], 5.3) | |
| A reaction: These are the reasons why necessity is denied in causation. i) is in the initial circumstances, ii) is another cause getting there first, iii) is a defusing action in the agent, iv) is a defusing action in the patient. No necessity if one is possible. |
| 22622 | Any process can go backwards or forwards in time without violating the basic laws of physics [Ingthorsson] |
| Full Idea: Because it makes no difference to exchange the time variable t with its contrary -t, in the fundamental laws of physics, any process can be described as going either backwards or forwards in time, without violating those laws. | |
| From: R.D. Ingthorsson (A Powerful Particulars View of Causation [2021], 4.13) | |
| A reaction: A few philosophers read a lot into this, but I don't. The inverse scenario may not breach the laws of physics, but it does involve time going backwards, which I think we can skip for now. Entropy would be interesting. Can information flow backwards? |
| 22618 | In modern physics the first and second laws of motion (unlike the third) fail at extremes [Ingthorsson] |
| Full Idea: While the first and second laws of motion are known to fail in the domain of very fast-moving and massive objects (i.e. where relativity deviates from classical mechanics) as well as in the quantum realm, the third law is still assumed to hold good. | |
| From: R.D. Ingthorsson (A Powerful Particulars View of Causation [2021], 4.04) | |
| A reaction: This implies a universal status for the third law (equal and opposite reactions), which the other two lack. Ingthorsson sees this as crucial for our understanding of causation. |
| 22630 | If particles have decay rates, they can't really be elementary, in the sense of indivisible [Ingthorsson] |
| Full Idea: We may wonder whether the fact that physics has calculated (and for some, confirmed) the decay rate of elementary particles can be a reason to think that they cannot really be ‘elementary’ in the philosophical sense of ‘indivisible’. | |
| From: R.D. Ingthorsson (A Powerful Particulars View of Causation [2021], 7.6) | |
| A reaction: I don't think anything can ever conclusively be labelled as 'elementary', but this idea offers a reason for doubting whether a candidate particle is so basic. Does decay imply having parts? |
| 22610 | It is difficult to handle presentism in first-order logic [Ingthorsson] |
| Full Idea: Contemporary philosophers are not comfortable with presentism, because it is difficult to deal with presentism in the language of first-order predicate logic. | |
| From: R.D. Ingthorsson (A Powerful Particulars View of Causation [2021], 1.8) | |
| A reaction: Presumable that logic relies on objects which endure through time, or at least have a past. Second-order logic is better able to deal with processes, which only exist in the present, but nevertheless have an integral past and future. ? |
