| 14767 | The demonstrations of the metaphysicians are all moonshine [Peirce] |
| Full Idea: The demonstrations of the metaphysicians are all moonshine. | |
| From: Charles Sanders Peirce (Concerning the Author [1897], p.2) |
| 14764 | I am saturated with the spirit of physical science [Peirce] |
| Full Idea: I am saturated, through and through, with the spirit of the physical sciences. | |
| From: Charles Sanders Peirce (Concerning the Author [1897], p.1) |
| 10688 | 'Equivocation' is when terms do not mean the same thing in premises and conclusion [Beall/Restall] |
| Full Idea: 'Equivocation' is when the terms do not mean the same thing in the premises and in the conclusion. | |
| From: JC Beall / G Restall (Logical Consequence [2005], Intro) |
| 10690 | Formal logic is invariant under permutations, or devoid of content, or gives the norms for thought [Beall/Restall] |
| Full Idea: Logic is purely formal either when it is invariant under permutation of object (Tarski), or when it has totally abstracted away from all contents, or it is the constitutive norms for thought. | |
| From: JC Beall / G Restall (Logical Consequence [2005], 2) | |
| A reaction: [compressed] The third account sounds rather woolly, and the second one sounds like a tricky operation, but the first one sounds clear and decisive, so I vote for Tarski. |
| 10691 | Logical consequence needs either proofs, or absence of counterexamples [Beall/Restall] |
| Full Idea: Technical work on logical consequence has either focused on proofs, where validity is the existence of a proof of the conclusions from the premises, or on models, which focus on the absence of counterexamples. | |
| From: JC Beall / G Restall (Logical Consequence [2005], 3) |
| 10695 | Logical consequence is either necessary truth preservation, or preservation based on interpretation [Beall/Restall] |
| Full Idea: Two different views of logical consequence are necessary truth-preservation (based on modelling possible worlds; favoured by Realists), or truth-preservation based on the meanings of the logical vocabulary (differing in various models; for Anti-Realists). | |
| From: JC Beall / G Restall (Logical Consequence [2005], 2) | |
| A reaction: Thus Dummett prefers the second view, because the law of excluded middle is optional. My instincts are with the first one. |
| 10689 | A step is a 'material consequence' if we need contents as well as form [Beall/Restall] |
| Full Idea: A logical step is a 'material consequence' and not a formal one, if we need the contents as well as the structure or form. | |
| From: JC Beall / G Restall (Logical Consequence [2005], 2) |
| 10696 | A 'logical truth' (or 'tautology', or 'theorem') follows from empty premises [Beall/Restall] |
| Full Idea: If a conclusion follows from an empty collection of premises, it is true by logic alone, and is a 'logical truth' (sometimes a 'tautology'), or, in the proof-centred approach, 'theorems'. | |
| From: JC Beall / G Restall (Logical Consequence [2005], 4) | |
| A reaction: These truths are written as following from the empty set Φ. They are just implications derived from the axioms and the rules. |
| 10693 | Models are mathematical structures which interpret the non-logical primitives [Beall/Restall] |
| Full Idea: Models are abstract mathematical structures that provide possible interpretations for each of the non-logical primitives in a formal language. | |
| From: JC Beall / G Restall (Logical Consequence [2005], 3) |
| 10692 | Hilbert proofs have simple rules and complex axioms, and natural deduction is the opposite [Beall/Restall] |
| Full Idea: There are many proof-systems, the main being Hilbert proofs (with simple rules and complex axioms), or natural deduction systems (with few axioms and many rules, and the rules constitute the meaning of the connectives). | |
| From: JC Beall / G Restall (Logical Consequence [2005], 3) |
| 14768 | Infallibility in science is just a joke [Peirce] |
| Full Idea: Infallibility in scientific matters seems to me irresistibly comical. | |
| From: Charles Sanders Peirce (Concerning the Author [1897], p.3) |
| 14765 | Association of ideas is the best philosophical idea of the prescientific age [Peirce] |
| Full Idea: The doctrine of the association of ideas is, to my thinking, the finest piece of philosophical work of the prescientific ages. | |
| From: Charles Sanders Peirce (Concerning the Author [1897], p.2) |
| 14766 | Duns Scotus offers perhaps the best logic and metaphysics for modern physical science [Peirce] |
| Full Idea: The works of Duns Scotus have strongly influenced me. …His logic and metaphysics, torn away from its medievalism, …will go far toward supplying the philosophy which is best to harmonize with physical science. | |
| From: Charles Sanders Peirce (Concerning the Author [1897], p.2) |
| 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. |
| 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. |
