| 16241 | The metaphysics of nature should focus on physics [Maudlin] |
| Full Idea: Metaphysics, insofar as it is concerned with the natural world, can do no better than to reflect on physics. | |
| From: Tim Maudlin (The Metaphysics within Physics [2007], Intro) | |
| A reaction: I suppose so. Physics only works at one level of description. Metaphysics often works with concepts which only emerge at a more general level than physics. There are also many metaphysical problems which are of no interest to most physicists. |
| 16257 | Kant survives in seeing metaphysics as analysing our conceptual system, which is a priori [Maudlin] |
| Full Idea: The Kantian strain survives in the notion that metaphysics is not about the world, but about our 'conceptual system', especially as what structures our thought about the world. This keeps it a priori, and so not about the world itself. | |
| From: Tim Maudlin (The Metaphysics within Physics [2007], 3) | |
| A reaction: Strawson would embody this view, I suppose. I take our conceptual system to be largely a reflection of (and even creation of) the world, and not just an arbitrary conventional attempt to grasp the world. Analysing concepts partly analyses the world. |
| 16276 | Wide metaphysical possibility may reduce metaphysics to analysis of fantasies [Maudlin] |
| Full Idea: If metaphysical possibility extends more widely than physical possibility, this may make metaphysics out to be nothing but the analysis of fantastical descriptions produced by philosophers. | |
| From: Tim Maudlin (The Metaphysics within Physics [2007], 7 Epilogue) | |
| A reaction: Maudlin wants metaphysics to be firmly constrained in its possibilities by what scientific undestanding permits, and he is right. Metaphysics must integrate into science, or wither away on the margins. |
| 16244 | If the universe is profligate, the Razor leads us astray [Maudlin] |
| Full Idea: If the universe has been profligate, then Ockham's Razor will lead us astray. | |
| From: Tim Maudlin (The Metaphysics within Physics [2007], Intro) | |
| A reaction: That is, there may be a vast number of entities which exist beyond what seems to be 'necessary'. |
| 16255 | The Razor rightly prefers one cause of multiple events to coincidences of causes [Maudlin] |
| Full Idea: The Razor is good when it councils higher credence to explanations which posit a single cause to multiple events that occur in a striking pattern, over explanations involving coincidental multiple causes. | |
| From: Tim Maudlin (The Metaphysics within Physics [2007], 2.5) | |
| A reaction: This is in the context of Maudlin warning against embracing the Razor too strongly. Presumably inductive success suggests that the world supports this particular use of the Razor. |
| 17884 | Mathematical set theory has many plausible stopping points, such as finitism, and predicativism [Koellner] |
| Full Idea: There are many coherent stopping points in the hierarchy of increasingly strong mathematical systems, starting with strict finitism, and moving up through predicativism to the higher reaches of set theory. | |
| From: Peter Koellner (On the Question of Absolute Undecidability [2006], Intro) |
| 17893 | 'Reflection principles' say the whole truth about sets can't be captured [Koellner] |
| Full Idea: Roughly speaking, 'reflection principles' assert that anything true in V [the set hierarchy] falls short of characterising V in that it is true within some earlier level. | |
| From: Peter Koellner (On the Question of Absolute Undecidability [2006], 2.1) |
| 17894 | We have no argument to show a statement is absolutely undecidable [Koellner] |
| Full Idea: There is at present no solid argument to the effect that a given statement is absolutely undecidable. | |
| From: Peter Koellner (On the Question of Absolute Undecidability [2006], 5.3) |
| 17890 | There are at least eleven types of large cardinal, of increasing logical strength [Koellner] |
| Full Idea: Some of the standard large cardinals (in order of increasing (logical) strength) are: inaccessible, Mahlo, weakly compact, indescribable, Erdös, measurable, strong, Wodin, supercompact, huge etc. (...and ineffable). | |
| From: Peter Koellner (On the Question of Absolute Undecidability [2006], 1.4) | |
| A reaction: [I don't understand how cardinals can have 'logical strength', but I pass it on anyway] |
| 17887 | PA is consistent as far as we can accept, and we expand axioms to overcome limitations [Koellner] |
| Full Idea: To the extent that we are justified in accepting Peano Arithmetic we are justified in accepting its consistency, and so we know how to expand the axiom system so as to overcome the limitation [of Gödel's Second Theorem]. | |
| From: Peter Koellner (On the Question of Absolute Undecidability [2006], 1.1) | |
| A reaction: Each expansion brings a limitation, but then you can expand again. |
| 17891 | Arithmetical undecidability is always settled at the next stage up [Koellner] |
| Full Idea: The arithmetical instances of undecidability that arise at one stage of the hierarchy are settled at the next. | |
| From: Peter Koellner (On the Question of Absolute Undecidability [2006], 1.4) |
| 16243 | The Humean view is wrong; laws and direction of time are primitive, and atoms are decided by physics [Maudlin] |
| Full Idea: The Humean project is unjustified, in that both the laws of nature and the direction of time require no analysis, and is misconceived, in that the atoms it employs do not correspond to present physical ontology. | |
| From: Tim Maudlin (The Metaphysics within Physics [2007], Intro) | |
| A reaction: I certainly find it strange, or excessively empirical, that Lewis thinks our account of reality should rest on 'qualities'. Maudlin's whole books is an implicit attack on David Lewis. |
| 16271 | Lewis says it supervenes on the Mosaic, but actually thinks the Mosaic is all there is [Maudlin] |
| Full Idea: At base it is not merely, as Lewis says, that everything else supervenes on the Mosaic; but rather that anything that exists at all is just a feature or element or generic property of the Mosaic. | |
| From: Tim Maudlin (The Metaphysics within Physics [2007], 6) | |
| A reaction: [Maudlin has just quoted Idea 16210] Correct about Lewis, but Lewis just has a normal view of supervenience. Only 'emergentists' would think the supervenience allowed anything more, and they are deeply misguided, and in need of help. |
| 16273 | If the Humean Mosaic is ontological bedrock, there can be no explanation of its structure [Maudlin] |
| Full Idea: The Humean Mosaic appears to admit of no further explanation. Since it is the ontological bedrock, …none of the further things can account for the structure of the Mosaic itself. | |
| From: Tim Maudlin (The Metaphysics within Physics [2007], 6) | |
| A reaction: A very nice point, reminiscent of Popper's objection to essentialism, that he thought it blocked further enquiry, when actually further enquiry was possible. Lewis and Hume seem too mesmerised by epistemology. They need best explanation. |
| 16275 | The 'spinning disc' is just impossible, because there cannot be 'homogeneous matter' [Maudlin] |
| Full Idea: The 'spinning disc' is not metaphysically possible. We have every reason to believe that there is no such thing as 'perfectly homogeneous matter'. The atomic theory of matter is as well established as any scientific theory is likely to be. | |
| From: Tim Maudlin (The Metaphysics within Physics [2007], 7 Epilogue) | |
| A reaction: This is a key case for Maudlin, and his contempt for metaphysics which is not scientifically informed. I agree with him. Extreme thought experiments are worth considering, but impossible ones are pointless. |
| 16258 | To get an ontology from ontological commitment, just add that some theory is actually true [Maudlin] |
| Full Idea: The doctrine of ontological commitment becomes a central element in a theory of ontology if one merely adds that a particular theory is, in fact, true | |
| From: Tim Maudlin (The Metaphysics within Physics [2007], 3.1) | |
| A reaction: Helpful. I don't think the truth of a theory entails the actual existence of every component mentioned in the theory, as some of them may be generalisations, abstractions, vague, or even convenient linking fictions. |
| 16259 | Naďve translation from natural to formal language can hide or multiply the ontology [Maudlin] |
| Full Idea: Naďve translation from natural language into formal language can obscure necessary ontology as easily as it can create superfluous ontological commitment. …The lion's share of metaphysical work is done when settling on the right translation. | |
| From: Tim Maudlin (The Metaphysics within Physics [2007], 3.1) | |
| A reaction: I suspect this is more than a mere problem of 'naivety', but may be endemic to the whole enterprise. If you hammer a square peg into a round hole, you expect to lose something. Language is subtle, logic is crude. |
| 16253 | A property is fundamental if two objects can differ in only that respect [Maudlin] |
| Full Idea: Fragility is not a fundamental physical property, in that two pieces of glass cannot be physically identical save for their fragility. | |
| From: Tim Maudlin (The Metaphysics within Physics [2007], 2.5) | |
| A reaction: Nice. The best idea I have found in Maudlin, so far! This gives a very nice test for picking out the fundamental physical and intrinsic properties. |
| 16263 | Fundamental physics seems to suggest there are no such things as properties [Maudlin] |
| Full Idea: If one believes that fundamental physics is the place to look for the truths about universals (or tropes or natural sets), then one may find that physics is telling us there are no such things. | |
| From: Tim Maudlin (The Metaphysics within Physics [2007], 3.2) | |
| A reaction: His prior discussion of quantum chromodynamics suggests, to me, merely that properties can be described in terms of vectors etc., and remains neutral on the ontology - but then I am blinded by science. |
| 16260 | Existence of universals may just be decided by acceptance, or not, of second-order logic [Maudlin] |
| Full Idea: On one line of thought, the question of whether universals exist seems to reduce to the question of the utility, or necessity, of using second-order rather than first-order logic. | |
| From: Tim Maudlin (The Metaphysics within Physics [2007], 3.1) | |
| A reaction: Second-order logic quantifies over properties, where first-order logic just quantifies over objects. This is an extreme example of doing your metaphysics largely through logic. Not my approach. |
| 16277 | Logically impossible is metaphysically impossible, but logically possible is not metaphysically possible [Maudlin] |
| Full Idea: While logical impossibility is a species of metaphysical impossibility, logical possibility is not a species of metaphysical possibility. The logically impeccable description 'Cicero was not Tully' describes a metaphysically impossible situation. | |
| From: Tim Maudlin (The Metaphysics within Physics [2007], 7 Epilogue) | |
| A reaction: The context of this is Maudlin attack on daft notions of metaphysical possibility that are at variance with the limits set by science, but he is still conceding that there are types of metaphysical modality. |
| 16249 | A counterfactual antecedent commands the redescription of a selected moment [Maudlin] |
| Full Idea: The purpose of the antecedent of a counterfactual is to provide instructions on how to pick a Cauchy surface (pick a moment in time) and how to generate an altered description of that moment. It is more of a command than an indicative sentence. | |
| From: Tim Maudlin (The Metaphysics within Physics [2007], 1.5) | |
| A reaction: Quite plausible, but the antecedent might contain no description. 'If things had gone differently, we wouldn't be in this mess'. The antecedent might be timeless. 'If pigs had wings, they still wouldn't fly'. |
| 16254 | Induction leaps into the unknown, but usually lands safely [Maudlin] |
| Full Idea: Induction is always a leap beyond the known, but we are constantly assured by later experience that we have landed safely. | |
| From: Tim Maudlin (The Metaphysics within Physics [2007], 2.5) | |
| A reaction: Not philosophically very interesting, but a nice remark for capturing the lived aspect of inductive thought, as practised by the humblest of animals. |
| 20043 | Evolutionary explanations look to the past or the group, not to the individual [Stout,R] |
| Full Idea: In evolutionary explanations you may explain a population trait in terms of what it is for the sake of an individual, or explain it in terms of what it was for the sake of in earlier generations, but never in terms of what the trait is for the sake of. | |
| From: Rowland Stout (Action [2005], 2 'Functions') | |
| A reaction: So my ears are for the sake of my ability to hear, but that does not explain why I have ears. Should we say there is 'impersonal teleology' here, but no 'personal teleology'? Interesting. |
| 16245 | Laws should help explain the things they govern, or that manifest them [Maudlin] |
| Full Idea: A law ought to be capable of playing some role in explaining the phenomena that are governed by or are manifestations of it. | |
| From: Tim Maudlin (The Metaphysics within Physics [2007], 1.2) | |
| A reaction: I find this attitude bewildering. 'Why do electrons have spin?' 'Because they all do!' The word 'governed' is the clue. What on earth is a law, if it can 'govern' nature? What is its ontological status? Natures of things are basic, not 'laws'. |
| 20058 | Not all explanation is causal. We don't explain a painting's beauty, or the irrationality of root-2, that way [Stout,R] |
| Full Idea: Not all explanation is causal. Explaining the beauty of a painting is not explaining why something happened. or why a move in chess is illegal, or why the square root of two is not a rational number. | |
| From: Rowland Stout (Action [2005], 5 'Argument') | |
| A reaction: It is surely plausible that the illegality of the chess move is caused (or 'determined', as I prefer to say) by the laws created for chess. The painting example seems right, though; what determined its configuration (think Pollock!) does not explain it. |
| 20035 | Philosophy of action studies the nature of agency, and of deliberate actions [Stout,R] |
| Full Idea: The philosophy of action is concerned with the nature of agency: what it is to be a full-blown agent, and what it is to realise one's agency in acting deliberately on things. | |
| From: Rowland Stout (Action [2005], 1 'Being') | |
| A reaction: 'Full-blown' invites the question of whether there could be a higher level of agency, beyond the capacity of human beings. Perhaps AI should design a theoretical machine that taps into those higher levels, if we can conceive of them. Meta-coherence! |
| 20084 | Agency is causal processes that are sensitive to justification [Stout,R] |
| Full Idea: My conclusion is that wherever you can identify causal processes that are sensitive to the recommendations of systems of justification, there you have found agency. | |
| From: Rowland Stout (Action [2005], 9b 'Conclusion') | |
| A reaction: [the last paragraph of his book] Justification seems an awfully grand notion for a bee pollinating a flower, and I don't see human action as profoundly different. A reason might be a bad justification, but it might not even aspire to be a justification. |
| 20061 | Mental states and actions need to be separate, if one is to cause the other [Stout,R] |
| Full Idea: If psychological states and action results cannot be identified independently of one another, then it does not make sense to describe one as causing the other. | |
| From: Rowland Stout (Action [2005], 5 'Conclusion') | |
| A reaction: This summarises a widely cited unease about the causal theory of action. Any account in action theory will need to separate out some components and explain their interrelation. Otherwise actions are primitives, and we can walk away. |
| 20079 | Are actions bodily movements, or a sequence of intention-movement-result? [Stout,R] |
| Full Idea: Are actions identical with bodily movements? Or are they identical with sequences of things starting inside the agent's mind with their intentions, going through their body movements and finishing with the external results being achieved? | |
| From: Rowland Stout (Action [2005], 9 'What is action') | |
| A reaction: If bodily movements are crucial, this presumably eliminates speech acts. Speech or writing may involve some movement, but the movement is almost irrelevant to the nature of the action. Telepathy would do equally well. |
| 20080 | If one action leads to another, does it cause it, or is it part of it? [Stout,R] |
| Full Idea: When we do one action 'by' doing another, either the first action causes the process of the second, or the first action is part of the process of the second | |
| From: Rowland Stout (Action [2005], 9 'What is by') | |
| A reaction: Stout says the second view is preferable, because pressing a switch does not cause my action of turning on the light (though it does cause the light to come on). |
| 20059 | I do actions, but not events, so actions are not events [Stout,R] |
| Full Idea: I do not do an event; I do an action; so actions are not events. | |
| From: Rowland Stout (Action [2005], 5 'Are actions') | |
| A reaction: Sounds conclusive, but it places a lot of weight on the concepts of 'I' and 'do', which leaves room for some discussion. This point is opposed to the causal theory of action, because causation concerns events. |
| 20081 | Bicycle riding is not just bodily movement - you also have to be on the bicycle [Stout,R] |
| Full Idea: You do not ride a bicycle just by moving your body in a certain way. You have to be on the bicycle to move in the right sort of way | |
| From: Rowland Stout (Action [2005], 9 'Are body') | |
| A reaction: My favourite philosophical ideas are simple and conclusive. He also observes that walking involves the ground being walked on. In complex actions 'feedback' with the environment is involved. |
| 20044 | The rationalistic approach says actions are intentional when subject to justification [Stout,R] |
| Full Idea: The rationalistic approach to agency says that what characterises intentional action is that it is subject to justification. | |
| From: Rowland Stout (Action [2005], 2 'Conclusion') | |
| A reaction: [Anscombe is the chief articulator of this view] This seems to incorporate action into an entirely intellectual and even moral framework. |
| 20039 | The causal theory says that actions are intentional when intention (or belief-desire) causes the act [Stout,R] |
| Full Idea: The causal theory of action asserts that what characterises intentional action is the agent's intentions, or perhaps their beliefs and desires, causing their behaviour in the appropriate way. | |
| From: Rowland Stout (Action [2005], 1 'Outline') | |
| A reaction: The agent's intentions are either sui generis (see Bratman), or reducible to beliefs and desires (as in Hume). The classic problem for the causal theory is said to be 'deviant causal chains'. |
| 20047 | Deciding what to do usually involves consulting the world, not our own minds [Stout,R] |
| Full Idea: In the vast majority of actions you need to look outwards to work out what you should do. An exam invigilator should consult the clock to design when to end the exam, not her state of mind. | |
| From: Rowland Stout (Action [2005], 3 'The belief-') | |
| A reaction: Stout defends externalist intentions. I remain unconvinced. It is no good looking at a clock if you don't form a belief about what it says, and the belief is obviously closer than the clock to the action. Intellectual virtue requires checking the facts. |
| 20065 | Should we study intentions in their own right, or only as part of intentional action? [Stout,R] |
| Full Idea: Should we try to understand what it is to have an intention in terms of what it is to act intentionally, or should we try to understand what it is to have an intention independently of what it is to act intentionally? | |
| From: Rowland Stout (Action [2005], 7 'Acting') | |
| A reaction: Since you can have an intention to act, and yet fail to act, it seems possible to isolate intentions, but not to say a lot about them. Intention may be different prior to actions, and during actions. Early Davidson offered the derived view. |
| 20067 | You can have incompatible desires, but your intentions really ought to be consistent [Stout,R] |
| Full Idea: Intentions are unlike desires. You can simultaneously desire two things that you know are incompatible. But when you form intentions you are embarking on a course of action, and there is a much stronger requirement of consistency. | |
| From: Rowland Stout (Action [2005], 7 'Relationship') | |
| A reaction: I'm not sure why anyone would identify intentions with desires. I would quite like to visit Japan, but have no current intention of doing so. I assume that the belief-plus-desire theory doesn't deny that an uninteresting intention is also needed. |
| 20078 | The normativity of intentions would be obvious if they were internal promises [Stout,R] |
| Full Idea: One way to incorporate this [normative] feature of intentions would be to treat them like internal promises. | |
| From: Rowland Stout (Action [2005], 8 'Intention') | |
| A reaction: Interesting. The concept of a promise is obviously closely linked to an intention. If you tell your companion exactly where you intend your golf ball to land, you can thereby be held accountable, in a manner resembling a promise (but not a promise). |
| 20036 | Intentional agency is seen in internal precursors of action, and in external reasons for the act [Stout,R] |
| Full Idea: It is plausible that we find something characteristic of intentional agency when we look inward to the mental precursors of actions, and also when we look outward, to the sensitivity of action to what the environment gives us reasons to do. | |
| From: Rowland Stout (Action [2005], 1 'How') | |
| A reaction: This is Stout staking a claim for his partly externalist view of agency. I warm less and less to the various forms of externalism. How often does the environment 'give us reasons' to do things? How can we act, without internalising those reasons? |
| 20066 | Speech needs sustained intentions, but not prior intentions [Stout,R] |
| Full Idea: The intentional action of including the word 'big' in a sentence does not require a prior intention to say it. What is required is that you say it with the intention of saying it. | |
| From: Rowland Stout (Action [2005], 7 'Relationship') | |
| A reaction: This seems right, but makes it a lot harder to say what an intention is, and to separate it out for inspection. You can't speak a good English sentence while withdrawing the intention involved. |
| 20073 | Bratman has to treat shared intentions as interrelated individual intentions [Stout,R] |
| Full Idea: Bratman has to construe what we think of as shared intentions as not literally involving shared intentions, but as involving interrelating of individual intentions. | |
| From: Rowland Stout (Action [2005], 7 'Conclusion') | |
| A reaction: Stout rejects this, for an account based on adaptability of behaviour. To me, naturalism and sparse ontology favour Bratman (1984) . I like my idea that shared intentions are conditional individual intentions. If the group refuses, I drop the intention. |
| 20069 | A request to pass the salt shares an intention that the request be passed on [Stout,R] |
| Full Idea: When one person says to another 'please pass the salt', and the other engages with this utterance and understands it, they share the intention that this request is passed from the first person to the second. | |
| From: Rowland Stout (Action [2005], 7 'Shared') | |
| A reaction: Simple and intriguing. We form an intention, and then ask someone else to take over our intention. When the second person takes over the intention, I give up the intention to acquire the salt, because it is on its way. It's political. |
| 20070 | An individual cannot express the intention that a group do something like moving a piano [Stout,R] |
| Full Idea: It is unnatural to describe an individual as intending that the group do something together. ...What could possibly express my intention that we move the piano upstairs? | |
| From: Rowland Stout (Action [2005], 7 'Shared') | |
| A reaction: Two possible answers: it makes sense if I have great authority within the group. 'I'm going to move the piano - you take that end'. Or, such expressions are implicitly conditional - 'I intend to move the piano (if you will also intend it)'. |
| 20071 | An intention is a goal to which behaviour is adapted, for an individual or for a group [Stout,R] |
| Full Idea: An individual intention is a goal to which an individual's behaviour adapts. A shared intention is a goal to which a group of people's behaviour collectively adapts. | |
| From: Rowland Stout (Action [2005], 7 'Shared') | |
| A reaction: This is part of Stout's externalist approach to actions. One would have thought that an intention was a state of mind, not a goal in the world. The individual's goal can be psychological, but a group's goal has to be an abstraction. |
| 20038 | If the action of walking is just an act of will, then movement of the legs seems irrelevant [Stout,R] |
| Full Idea: If volitionism identifies the action with an act of will, this has the unpalatable consequence (for a Cartesian dualist) that walking does not happen in the material world. It would be the same act of walking if you had no legs, or no body at all. | |
| From: Rowland Stout (Action [2005], 1 'Volitionism') | |
| A reaction: Is this attacking a caricature version of volitionism? Descartes would hardly subscribe to the view that no legs are needed for walking. If my legs spasmodically move without an act of will, we typically deny that this is an action. |
| 20050 | Most philosophers see causation as by an event or state in the agent, rather than the whole agent [Stout,R] |
| Full Idea: Most philosophers are uneasy with understanding the causal aspect of actions in terms of an 'agent' making something happen. They prefer to think of some event in the agent, or state of the agent, making something happen. | |
| From: Rowland Stout (Action [2005], 4 'The causal') | |
| A reaction: There is a bit of a regress if you ask what caused the event or state of affairs. It is tempting to stop the buck at the whole agent, or else carry the reduction on down to neurons, physics and the outside world. |
| 20052 | If you don't mention an agent, you aren't talking about action [Stout,R] |
| Full Idea: Once you lose the agent from an account of action it stops being an account of action at all. | |
| From: Rowland Stout (Action [2005], 4 'Agent') | |
| A reaction: [he refers to Richard Taylor 1966] This could be correct without implying that agents offer a unique mode of causation. The concept of 'agent' is reducible. |
| 20077 | If you can judge one act as best, then do another, this supports an inward-looking view of agency [Stout,R] |
| Full Idea: Weakness of will is a threat to the outward-looking approach to agency. It seems you can hold one thing to be the thing to do, and at the same time do something else. Many regard this as a decisive reason to follow a more inward-looking approach. | |
| From: Rowland Stout (Action [2005], 8 'Weakness') | |
| A reaction: It hadn't struck me before that weakness of will is a tool for developing an accurate account of what is involved in normal agency. Some facts that guide action are internal to the agent, such as greed for sugary cakes. |
| 20049 | Maybe your emotions arise from you motivations, rather than being their cause [Stout,R] |
| Full Idea: Instead of assuming that your motivation depends on your emotional state, we might say that your emotional state depends on how you are motivated to act. | |
| From: Rowland Stout (Action [2005], 3 'Emotions') | |
| A reaction: [He says this move is made by Kant, Thomas Nagel and McDowell] Stout favours the view that it is external facts which mainly give rise to actions, and presumably these facts are intrinsically motivating, prior to any emotions. I don't disagree. |
| 20046 | For an ascetic a powerful desire for something is a reason not to implement it [Stout,R] |
| Full Idea: If wanting something most were the same as having the most powerful feelings about it, then as an ascetic (rejecting what you most powerfully desire), your wanting most to eat a bun would be your reason for not eating the bun. | |
| From: Rowland Stout (Action [2005], 3 'The belief-') | |
| A reaction: This sounds like reason overruling desire, but the asceticism can always be characterised as a meta-desire. |
| 20060 | Beliefs, desires and intentions are not events, so can't figure in causal relations [Stout,R] |
| Full Idea: Beliefs, desires and intentions are states of mind rather than events, but events are the only things that figure in causal relations. | |
| From: Rowland Stout (Action [2005], 5 'Do beliefs') | |
| A reaction: This is exactly why we have the concept of 'the will' - because it is a mental state to which we attribute active causal powers. We then have to explain how this 'will' is related to the other mental states (which presume motivate or drive it?). |
| 20055 | A standard view says that the explanation of an action is showing its rational justification [Stout,R] |
| Full Idea: The idea running through the work of Aristotle, Kant, Anscombe and Davidson is that explanation of action involves justifying that action or making it rationally intelligible. | |
| From: Rowland Stout (Action [2005], 5 'Psychological') | |
| A reaction: Stout goes on to say that instead you could give the 'rationalisation' of the action, which is psychological facts which explain the action, without justifying it. The earlier view may seem a little optimistic and intellectualist. |
| 20056 | In order to be causal, an agent's reasons must be internalised as psychological states [Stout,R] |
| Full Idea: It is widely accepted that to get involved in the causal process of acting an agent's reasons must be internalised as psychological states. | |
| From: Rowland Stout (Action [2005], 5 'Psychological') | |
| A reaction: This doesn't say whether the 'psychological states' have to be fully conscious. That seems unlikely, given the speed with which we perform some sequences of actions, such as when driving a car, or playing a musical instrument. |
| 20053 | An action is only yours if you produce it, rather than some state or event within you [Stout,R] |
| Full Idea: For action to be properly yours it must be you who is the causal originator of the action, rather than some state or event within you. | |
| From: Rowland Stout (Action [2005], 4 'Agent') | |
| A reaction: [He invokes Chisholm 1966] The idea here is that we require not only 'agent causation', but that the concept of agent must include free will. It seems right we ought to know whether or not an action is 'mine'. Nothing too fancy is needed for this! |
| 20048 | There may be a justification relative to a person's view, and yet no absolute justification [Stout,R] |
| Full Idea: In a relativistic notion of justification, in a particular system, there is a reason for a vandal to smash public property, even though, using an absolute conception of justification, there is no reason for him to do so. | |
| From: Rowland Stout (Action [2005], 3 'The difference') | |
| A reaction: I suppose Kantians would say that the aim of morality is to make your personal (relative) justification coincide with what seems to be the absolute justification. |
| 20068 | Describing a death as a side-effect rather than a goal may just be good public relations [Stout,R] |
| Full Idea: The real signficance of the doctrine of double effect can be public relations. You can put a better spin on an action by describing a death as an unfortunate collateral consequence, rather than as a goal of the action | |
| From: Rowland Stout (Action [2005], 7 'Doctrine') | |
| A reaction: The problem is that it the principle is usually invoked in situations where it is not clear where some bad effect is intended, and it is very easy to lie in such situations. In football, we can never quite decide whether a dangerous tackle was intended. |
| 20083 | Aristotelian causation involves potentiality inputs into processes (rather than a pair of events) [Stout,R] |
| Full Idea: In the Aristotelian approach to causation (unlike the Humean approach, involving separate events), A might cause B by being an input into some process (realisation of potentiality) that results in B. | |
| From: Rowland Stout (Action [2005], 9 'Trying') | |
| A reaction: Stout relies quite heavily on this view for his account of human action. I like processes, so am sympathetic to this view. If there are two separate events, it is not surprising that Hume could find nothing to bridge the gap between them. |
| 16248 | Evaluating counterfactuals involves context and interests [Maudlin] |
| Full Idea: The evaluation of counterfactual claims is widely recognised as being influenced by context and interest. | |
| From: Tim Maudlin (The Metaphysics within Physics [2007], 1.5) | |
| A reaction: Such evaluation certainly seems to involve imagination, and so the pragmatics can creep in there. I don't quite see why it should be deeply contextual. |
| 16250 | We don't pick a similar world from many - we construct one possibility from the description [Maudlin] |
| Full Idea: It seems unlikely the psychological process could mirror Lewis's semantics: people don't imagine a multiplicity of worlds and the pick out the most similar. Rather we construct representations of possible worlds from counterfactual descriptions. | |
| From: Tim Maudlin (The Metaphysics within Physics [2007], 1.5) | |
| A reaction: I approve of fitting such theories into a psychology, but this may be unfair to Lewis, who aims for a logical model, not an account of how we actually approach the problem. |
| 16268 | The counterfactual is ruined if some other cause steps in when the antecedent fails [Maudlin] |
| Full Idea: A counterexample to the counterfactual approach is that perhaps the effect would have occurred despite the absence of the cause since another cause would have stepped in to bring it about. | |
| From: Tim Maudlin (The Metaphysics within Physics [2007], 5) | |
| A reaction: …Hence you cannot say 'if C had not occurred, E would definitely not have occurred'. You have to add 'ceteris paribus', which ruins the neatness of the theory. |
| 16267 | If we know the cause of an event, we seem to assent to the counterfactual [Maudlin] |
| Full Idea: When we think we know the cause of an event, we typically assent to the corresponding Hume counterfactual. | |
| From: Tim Maudlin (The Metaphysics within Physics [2007], 5) | |
| A reaction: This is the correct grounding of the counterfactual approach - not that we think counterfactuals are causation, but that knowledge of causation will map neatly onto a network of counterfactuals, thus providing a logic for the whole process. |
| 16269 | If the effect hadn't occurred the cause wouldn't have happened, so counterfactuals are two-way [Maudlin] |
| Full Idea: If Kennedy had still been President in Dec 1963, he would not have been assassinated in Nov 1963, so the counterfactual goes both ways (where the cause seems to only go one way). | |
| From: Tim Maudlin (The Metaphysics within Physics [2007], 5) | |
| A reaction: Maudlin says a lot of fine-tuning has sort of addressed these problems, but that counterfactual causation is basically wrong-headed anyway, and I incline to agree, though one must understand what the theory is (and is not) trying to do. |
| 16247 | Laws are primitive, so two indiscernible worlds could have the same laws [Maudlin] |
| Full Idea: Laws are ontologically primitives at least in that two worlds could differ in their laws but not in any observable respect. ….[21] I take content of the laws to be expressed by equations. | |
| From: Tim Maudlin (The Metaphysics within Physics [2007], 1.4) | |
| A reaction: At least that spells out his view fairly dramatically, but I am baffled as to what he thinks a law could be. He is arguing against the Lewis regularity-axioms view, and the Armstrong universal-relations view. He ignores the essentialist view. |
| 16272 | Fundamental laws say how nature will, or might, evolve from some initial state [Maudlin] |
| Full Idea: The fundamental laws of nature appear to be laws of temporal evolution: they specify how the state of the universe will, or might, evolve from a given intial state. | |
| From: Tim Maudlin (The Metaphysics within Physics [2007], 6) | |
| A reaction: Maudlin takes both laws of nature and the passage of time to be primitive facts, and this is how they are connected. I think (this week) that I take time and causation to be primitive, but not laws. |
| 16242 | Laws of nature are ontological bedrock, and beyond analysis [Maudlin] |
| Full Idea: The laws of nature stand in no need of 'philosophical analysis'; they ought to be posited as ontological bedrock. | |
| From: Tim Maudlin (The Metaphysics within Physics [2007], Intro) | |
| A reaction: This is Maudlin's most basic principle, and I don't agree with it. The notion that laws are more deeply embedded in reality than the physical stuff they control is a sort of 'law-mysticism' that needs to be challenged. |
| 16251 | 'Humans with prime house numbers are mortal' is not a law, because not a natural kind [Maudlin] |
| Full Idea: 'All humans who live in houses with prime house numbers are mortal' is not a law because the class referred to is not a natural kind. | |
| From: Tim Maudlin (The Metaphysics within Physics [2007], 1.6) | |
| A reaction: Maudlin wants laws to be primitive, but he now needs a primitive notion of a natural kind to make it work. If kinds generate laws, you can ditch the laws, and build your theory on the kinds. He also says no death is explained by 'all humans are mortal'. |
| 16270 | If laws are just regularities, then there have to be laws [Maudlin] |
| Full Idea: On the Mill-Ramsey-Lewis account of laws, I take it that if the world is extensive and variegated enough, then there must be laws. | |
| From: Tim Maudlin (The Metaphysics within Physics [2007], 5.2) | |
| A reaction: A nice point. If there is any sort of pattern discernible in the surface waves on the sea, then there must be a law to cover it, not matter how vague or complex. |
| 16264 | I believe the passing of time is a fundamental fact about the world [Maudlin] |
| Full Idea: I believe that it is a fundamental, irreducible fact about the spatio-temporal structure of the world that time passes. | |
| From: Tim Maudlin (The Metaphysics within Physics [2007], 4) | |
| A reaction: Worth quoting because it comes from a philosopher fully informed about, and heavily committed to, the physicist's approach to reality. One fears that physicists steeped in Einstein are all B-series Eternalists. Get a life! |
| 16265 | If time passes, presumably it passes at one second per second [Maudlin] |
| Full Idea: It is necessary and, I suppose, a priori that if time passes at all it passes at one second per second. …Similarly, the fair exchange rate for a dollar must be a dollar. | |
| From: Tim Maudlin (The Metaphysics within Physics [2007], 4.1) | |
| A reaction: [He is discussing Huw Price on time] This is a reply to the claim that if time passes it has to pass at some rate, and 'one second per second' is ridiculous. Not very convincing, even with the dollar analogy. |
| 16266 | There is one ordered B series, but an infinitude of A series, depending on when the present is [Maudlin] |
| Full Idea: Given events ordered in a B series, one defines an infinitude of different A series that correspond to taking different events as 'now' or 'present'. McTaggart talks of 'the A series' when there is an infinitude of such. | |
| From: Tim Maudlin (The Metaphysics within Physics [2007], 4.3 n11) | |
| A reaction: This strikes me as a rather mathematical (and distorted) claim about the A series view. The A-series is one dynamic happening. Not an infinity of static times lines, each focused on a different 'now'. |
