5333 | Philosophy needs wisdom about who we are, as well as how we ought to be [Flanagan] |
Full Idea: Any good philosophy will need to offer wisdom about who we are as well as about how we ought to be. | |
From: Owen Flanagan (The Problem of the Soul [2002], p. 14) | |
A reaction: This sop should be accepted gratefully by fans of bioethics, who seem inclined to think that describing 'how we are' is all that needs to be said. Maybe the key wisdom lies in the relationship between the 'is' and the 'ought' of human nature. |
5334 | We resist science partly because it can't provide ethical wisdom [Flanagan] |
Full Idea: The inability of science to provide ethical wisdom is partly responsible for our resistance to the scientific image. | |
From: Owen Flanagan (The Problem of the Soul [2002], p. 14) | |
A reaction: This seems right. A.J. Ayer, for example, declared "I believe in science", and his account of ethics was vacuously nihilistic. A description of the mechanisms of moral life is not the same as ethical wisdom. |
8195 | Undecidable statements result from quantifying over infinites, subjunctive conditionals, and the past tense [Dummett] |
Full Idea: I once wrote that there are three linguistic devices that make it possible for us to frame undecidable statements: quantification over infinity totalities, as expressed by word such as 'never'; the subjunctive conditional form; and the past tense. | |
From: Michael Dummett (Truth and the Past [2001], 4) | |
A reaction: Dummett now repudiates the third one. Statements containing vague concepts also appear to be undecidable. Personally I have no problems with deciding (to a fair extent) about 'never x', and 'if x were true', and 'it was x'. |
8194 | Surely there is no exact single grain that brings a heap into existence [Dummett] |
Full Idea: There is surely no number n such that "n grains of sand do not make a heap, although n+1 grains of sand do" is true. | |
From: Michael Dummett (Truth and the Past [2001], 4) | |
A reaction: It might be argued that there is such a number, but no human being is capable of determing it. Might God know the value of n? On the whole Dummett's view seems the most plausible. |
8190 | Intuitionists rely on the proof of mathematical statements, not their truth [Dummett] |
Full Idea: The intuitionist account of the meaning of mathematical statements does not employ the notion of a statement's being true, but only that of something's being a proof of the statement. | |
From: Michael Dummett (Truth and the Past [2001], 2) | |
A reaction: I remain unconvinced that anyone could give an account of proof that didn't discreetly employ the notion of truth. What are we to make of "we suspect this is true, but no one knows how to prove it?" (e.g. Goldbach's Conjecture). |
8198 | A 'Cambridge Change' is like saying 'the landscape changes as you travel east' [Dummett] |
Full Idea: The idea of 'Cambridge Change' is like saying 'the landscape changes as you travel east'. | |
From: Michael Dummett (Truth and the Past [2001], 5) | |
A reaction: The phrase was coined in Oxford. It is a useful label with which realists can insult solipsists, idealists and other riff-raff. Four Dimensionalists seem to see time in this way. Events sit there, and we travel past them. But there are indexical events. |
8192 | I no longer think what a statement about the past says is just what can justify it [Dummett] |
Full Idea: In distinguishing between what can establish a statement about the past as true and what it is that that statement says, we are repudiating antirealism about the past. | |
From: Michael Dummett (Truth and the Past [2001], 3) | |
A reaction: This is a late shift of ground from the champion of antirealism. If Dummett's whole position is based on a 'justificationist' theory of meaning, he must surely have a different theory of meaning now for statements about the past? |
8199 | The existence of a universe without sentience or intelligence is an unintelligible fantasy [Dummett] |
Full Idea: The existence of a universe from which sentience was permanently absent is an unintelligible fantasy. What exists is what can be known to exist. What is true is what can be known to be true. Reality is what can be experienced and known. | |
From: Michael Dummett (Truth and the Past [2001], 5) | |
A reaction: This strikes me as nonsense. The fact that we cannot think about a universe without introducing a viewpoint does not mean that we cannot 'intellectually imagine' its existence devoid of viewpoints. Nothing could ever experience a star's interior. |
5340 | Explanation does not entail prediction [Flanagan] |
Full Idea: Explanation does not entail prediction. | |
From: Owen Flanagan (The Problem of the Soul [2002], p. 73n) | |
A reaction: Presumably the inverse of this is also true, as we might be able to predict through pure induction, without knowing why something happened. We predict that smoking is likely to cause cancer. Complex things might be explicable but unpredictable. |
12790 | Generalisations must be invariant to explain anything [Leuridan] |
Full Idea: A generalisation is explanatory if and only if it is invariant. | |
From: Bert Leuridan (Can Mechanisms Replace Laws of Nature? [2010], §4) | |
A reaction: [He cites Jim Woodward 2003] I dislike the idea that generalisations and regularities explain anything at all, but this rule sounds like a bare minimum for being taken seriously in the space of explanations. |
12789 | Biological functions are explained by disposition, or by causal role [Leuridan] |
Full Idea: The main alternative to the dispositional theory of biological functions (which confer a survival-enhancing propensity) is the etiological theory (effects are functions if they play a role in the causal history of that very component). | |
From: Bert Leuridan (Can Mechanisms Replace Laws of Nature? [2010], §3) | |
A reaction: [Bigelow/Pargetter 1987 for the first, Mitchell 2003 for the second] The second one sounds a bit circular, but on the whole a I prefer causal explanations to dispositional explanations. |
14386 | Mechanisms are ontologically dependent on regularities [Leuridan] |
Full Idea: Mechanisms are ontologically dependent on the existence of regularities. | |
From: Bert Leuridan (Can Mechanisms Replace Laws of Nature? [2010], §3) | |
A reaction: This seems to be the Humean rearguard action in favour of the regularity account of laws. Wrong, but a nice paper. This point shows why only powers (despite their vagueness!) are the only candidate for the bottom level of explanation. |
12787 | Mechanisms can't explain on their own, as their models rest on pragmatic regularities [Leuridan] |
Full Idea: To model a mechanism one must incorporate pragmatic laws. ...As valuable as the concept of mechanism and mechanistic explanation are, they cannot replace regularities nor undermine their relevance for scientific explanation. | |
From: Bert Leuridan (Can Mechanisms Replace Laws of Nature? [2010], §1) | |
A reaction: [See Idea 12786 for 'pragmatic laws'] I just don't see how the observation of a regularity is any sort of explanation. I just take a regularity to be something interesting which needs to be explained. |
14384 | We can show that regularities and pragmatic laws are more basic than mechanisms [Leuridan] |
Full Idea: Summary: mechanisms depend on regularities, there may be regularities without mechanisms, models of mechanisms must incorporate pragmatic laws, and pragmatic laws do not depend epistemologically on mechanistic models. | |
From: Bert Leuridan (Can Mechanisms Replace Laws of Nature? [2010], §1) | |
A reaction: See Idea 14382 for 'pragmatic' laws. I'm quite keen on mechanisms, so this is an arrow close to the heart, but at this point I say that my ultimate allegiance is to powers, not to mechanisms. |
14388 | Mechanisms must produce macro-level regularities, but that needs micro-level regularities [Leuridan] |
Full Idea: Nothing can count as a mechanism unless it produces some macro-level regular behaviour. To produce macro-level regular behaviour, it has to rely on micro-level regularities. | |
From: Bert Leuridan (Can Mechanisms Replace Laws of Nature? [2010], §5) | |
A reaction: This is the core of Leuridan's argument that regularities are more basic than mechanisms. It doesn't follow, though, that the more basic a thing is the more explanatory work it can do. I say mechanisms explain more than low-level regularities do. |
14389 | There is nothing wrong with an infinite regress of mechanisms and regularities [Leuridan] |
Full Idea: I see nothing metaphysically wrong in an infinite ontological regress of mechanisms and regularities. | |
From: Bert Leuridan (Can Mechanisms Replace Laws of Nature? [2010], §5) | |
A reaction: This is a pretty unusual view, and I can't accept it. My revulsion at this regress is precisely the reason why I believe in powers, as the bottom level of explanation. |
5346 | In the 17th century a collisionlike view of causation made mental causation implausible [Flanagan] |
Full Idea: In the seventeenth century the dominant idea that causation is collisionlike made mental causation almost impossible to envision. | |
From: Owen Flanagan (The Problem of the Soul [2002], p.136) | |
A reaction: Interesting. This makes Descartes' interaction theory look rather bold, and Leibniz's and Malebranche's rejection of it understandable. Personally I still think of causation as collisionlike, except that the collisions are of very very tiny objects. |
5341 | Only you can have your subjective experiences because only you are hooked up to your nervous system [Flanagan] |
Full Idea: It is easy to explain why certain brain events are uniquely experienced by you subjectively: only you are properly hooked up to your own nervous system to have your own experiences. | |
From: Owen Flanagan (The Problem of the Soul [2002], p. 87) | |
A reaction: This is in reply to Nagel's oft quoted claim that mind can only be understood as "what it is like to be" that mind. I agree with Flanagan, and it is nice illustration of how philosophers can confuse themselves with high-sounding questions. |
5351 | We only have a sense of our self as continuous, not as exactly the same [Flanagan] |
Full Idea: We only have a sense of our self as continuous, but not as exactly the same. | |
From: Owen Flanagan (The Problem of the Soul [2002], p.178) | |
A reaction: Russell said this too, and it seems to me to be right. Personal identity is far too imprecise for me to assert that I remember my ten-year-old self as being identical to me now. Only physical objects like teddy bears can pass that test. |
5353 | The self is an abstraction which magnifies important aspects of autobiography [Flanagan] |
Full Idea: The self is an abstraction from the story of a person's life that isolates and magnifies the experiences, traits and aspirations that are assigned importance. | |
From: Owen Flanagan (The Problem of the Soul [2002], p.240) | |
A reaction: Personally I am inclined to see personal identity as the central controller of brain activity, the aspect of the biological machine which keeps all the mental events focused on what matters, which is health, safety and happiness. |
5354 | We are not born with a self; we develop a self through living [Flanagan] |
Full Idea: It is a bad mistake to think we are born with a self; the self develops, and acquiring it requires living in the world. | |
From: Owen Flanagan (The Problem of the Soul [2002], p.260) | |
A reaction: I think this is wrong. He is mistaking a complex cultural concept of the self as the subject for autobiography etc. for the basic biological self which even small animals must have if their brains are to serve any useful purpose in their lives. |
5349 | For Buddhists a fixed self is a morally dangerous illusion [Flanagan] |
Full Idea: According to Buddhism, the idea of a permanent, constant self is an illusion, and a morally dangerous one. | |
From: Owen Flanagan (The Problem of the Soul [2002], p.161) | |
A reaction: We are familiar with the idea that it might be an illusion, but I am unconvinced by 'morally dangerous'. If you drop both free will and personal identity, I can't see any sort of focus for moral life left, but I am willing to be convinced. |
5338 | Normal free will claims control of what I do, but a stronger view claims control of thought and feeling [Flanagan] |
Full Idea: The standard view of free will is that I have something like complete control over what I do. A stronger view (not widely held) is that I also have complete control over what I think and what I feel. | |
From: Owen Flanagan (The Problem of the Soul [2002], p. 60n) | |
A reaction: To claim free control of feelings looks optimistic, but it does look as if we can decide to think about something, such as a philosophical problem. Deciding what to say comes somewhere between thought and action. |
5344 | Free will is held to give us a whole list of desirable capacities for living [Flanagan] |
Full Idea: Free will is said to give us self-control, self-expression, individuality, reasons-sensitivity, rational deliberation, rational accountability, moral accountability, the capacity to do otherwise, unpredictability, and political freedom. | |
From: Owen Flanagan (The Problem of the Soul [2002], p.104) | |
A reaction: Nice list. His obvious challenge is to either say we can live happily without some of these things, or else show how we can have them without 'free will'. Personally I agree with Flanagan that we meet the challenge. |
5332 | People believe they have free will that circumvents natural law, but only an incorporeal mind could do this [Flanagan] |
Full Idea: Most people believe we have free will, and that this consists in the ability to circumvent natural law. The trouble is that the only device ever philosophically invented that can do this sort of job is an incorporeal soul or mind. | |
From: Owen Flanagan (The Problem of the Soul [2002], Pref) | |
A reaction: I think this is exactly right. We currently have a western world full of people who have rejected dualism, but still cling on to free will, because they think morality depends on it. I think morality depends on personal identity, but not on free will. |
5345 | We only think of ourselves as having free will because we first thought of God that way [Flanagan] |
Full Idea: It is unimaginable to me that, despite the feeling that we control what we do, such a strong conception of ourselves as unmoved movers would have been added to our self-image unless we had first conceived of God along these lines. | |
From: Owen Flanagan (The Problem of the Soul [2002], p.107) | |
A reaction: I think this is right, though there are signs in fifth century Greece of contradictory evidence. The 'unmoved mover' seems unformulated before Plato's 'Laws' (idea 1423), but there is an implied belief in free will a hundred years earlier. |
5343 | People largely came to believe in dualism because it made human agents free [Flanagan] |
Full Idea: I would say that that my consciousness doesn't seem either physical or non-physical, ..but the belief that the mind is non-physical partly took hold because that fits well with thinking of human agents as free. | |
From: Owen Flanagan (The Problem of the Soul [2002], p.102) | |
A reaction: I think this is right. I personally think there is no such thing as free will, and that belief in it has been the single greatest delusion amongst philosophers (and others) for the last two thousand years. Dualism has now gone, and free will is next. |
5347 | Behaviourism notoriously has nothing to say about mental causation [Flanagan] |
Full Idea: Behaviourism was notorious in its heyday for having nothing to say about mental causation. | |
From: Owen Flanagan (The Problem of the Soul [2002], p.141) | |
A reaction: This is a bit unfair, as Ryle (idea 2622, following Spinoza, 4862) was one of the first to point out the paradox of 'double causation'. You have to be a mentalist to worry about mental causation, and eliminativists aren't bothered. |
5339 | Cars and bodies obey principles of causation, without us knowing any 'strict laws' about them [Flanagan] |
Full Idea: Although everyone thinks cars and bodies obey the principles of causation, no one thinks it a deficiency that we don't know strict laws of automechanics or anatomy. | |
From: Owen Flanagan (The Problem of the Soul [2002], p. 65) | |
A reaction: This attacks Davidson's claim that there are no strict psycho-physical laws, and I agree with Flanagan. Huge dreams of free will and human dignity are being pinned on the flimsy point that we have no strict laws here. But brains are very complicated. |
5342 | Physicalism doesn't deny that the essence of an experience is more than its neural realiser [Flanagan] |
Full Idea: One may be committed to the truth of physicalism without being committed to the claim that the essence of an experience is captured fully by a description of its neural realiser. | |
From: Owen Flanagan (The Problem of the Soul [2002], p. 90) | |
A reaction: This is a reply to the Leibniz Mill question (idea 2109) about what is missing from a materialist view. Flanagan's point is that just as the essence of a panorama is the view from the hill, so the essence of consciousness requires you to be that brain. |
5335 | Emotions are usually very apt, rather than being non-rational and fickle [Flanagan] |
Full Idea: One can question the idea that emotions are non-rational, fickle and flighty; on the contrary, emotions normally seem to be very apt. | |
From: Owen Flanagan (The Problem of the Soul [2002], p. 16) | |
A reaction: This is the modern view of emotion which is emerging from neuroscience, which is greatly superior to traditional views, apart from Aristotle, who felt that wisdom and virtue arose precisely when emotions were apt for the situation. |
8193 | Verification is not an individual but a collective activity [Dummett] |
Full Idea: Verification is not an individual but a collective activity. | |
From: Michael Dummett (Truth and the Past [2001], 3) | |
A reaction: This generates problems. Are deceased members of the community included? (Yes, says Dummett). If someone speaks to angels (Blake!), do they get included? Is a majority necessary? What of weird loners? Etc. |
8189 | Truth-condition theorists must argue use can only be described by appeal to conditions of truth [Dummett] |
Full Idea: To demonstrate the necessity of a truth-conditional theory of meaning, a proponent of such a theory must argue that use cannot be described without appeal to the conditions for the truth of statements. | |
From: Michael Dummett (Truth and the Past [2001], 1) | |
A reaction: Unlike Dummett, I find that argument rather appealing. How do you decide the possible or appropriate use for a piece of language, if you don't already know what it means. Basing it all on social conventions means it could be meaningless ritual. |
8191 | The truth-conditions theory must get agreement on a conception of truth [Dummett] |
Full Idea: It is not enough for the truth-condition theorist to argue that we need the concept of truth: he must show that we should have the same conception of truth that he has. | |
From: Michael Dummett (Truth and the Past [2001], 2) | |
A reaction: Davidson invites us to accept Tarski's account of truth. It invites the question of what the theory would be like with a very robust correspondence account of truth, or a flabby rather subjective coherence view, or the worst sort of pragmatic view. |
5348 | Intellectualism admires the 'principled actor', non-intellectualism admires the 'good character' [Flanagan] |
Full Idea: There are two main pictures of the good person: there is the 'good character', and there is the 'principled actor'. ..The first picture is non-intellectualist, and the second is intellectualist. | |
From: Owen Flanagan (The Problem of the Soul [2002], p.145) | |
A reaction: The second ideal elevates the principle itself above the actor who carries it out. Presumably consistency is a virtue, so a good character will at least pay some attention to principles. A good magistrate comes out the same in both views. |
5355 | Cognitivists think morals are discovered by reason [Flanagan] |
Full Idea: Cognitivists think morals are discovered by reason. | |
From: Owen Flanagan (The Problem of the Soul [2002], p.301n) | |
A reaction: I take cognitivism to be (strictly) the view that morals are knowable in principle. Our intellects might not be up to the task (and so we might have to ask the gods what is right). There is also the possibility that morals might be known by intuition. |
5336 | Ethics is the science of the conditions that lead to human flourishing [Flanagan] |
Full Idea: Ethics is the normative science that studies the objective conditions that lead to flourishing of persons. | |
From: Owen Flanagan (The Problem of the Soul [2002], p. 17) | |
A reaction: This is a nice slogan for the virtue theory account of the nature of ethics. I think it is the view with which I agree. I am intrigued that he has smuggled the word 'science' in, which is a nice challenge to conventional views of science. |
14387 | Rather than dispositions, functions may be the element that brought a thing into existence [Leuridan] |
Full Idea: The dispositional theory of biological functions is not unquestioned. The main alternative is the etiological theory: a component's effect is a function of that component if it has played an essential role in the causal history of its existence. | |
From: Bert Leuridan (Can Mechanisms Replace Laws of Nature? [2010], §3) | |
A reaction: [He cites S.D. Mitchell 2003] Presumably this account is meant to fit into a theory of evolution in biology. The obvious problem is where something comes into existence for one reason, and then acquires a new function (such as piano-playing). |
14382 | Pragmatic laws allow prediction and explanation, to the extent that reality is stable [Leuridan] |
Full Idea: A generalization is a 'pragmatic law' if it allows of prediction, explanation and manipulation, even if it fails to satisfy the traditional criteria. To this end, it should describe a stable regularity, but not necessarily a universal and necessary one. | |
From: Bert Leuridan (Can Mechanisms Replace Laws of Nature? [2010], §1) | |
A reaction: I am tempted to say of this that all laws are pragmatic, given that it is rather hard to know whether reality is stable. The universal laws consist of saying that IF reality stays stable in certain ways, certain outcomes will ensue necessarily. |
14385 | Strict regularities are rarely discovered in life sciences [Leuridan] |
Full Idea: Strict regularities are rarely if ever discovered in the life sciences. | |
From: Bert Leuridan (Can Mechanisms Replace Laws of Nature? [2010], §2) | |
A reaction: This is elementary once it is pointed out, but too much philosophy have science has aimed at the model provided by the equations of fundamental physics. Science is a broad church, to employ an entertaining metaphor. |
14383 | A 'law of nature' is just a regularity, not some entity that causes the regularity [Leuridan] |
Full Idea: By 'law of nature' or 'natural law' I mean a generalization describing a regularity, not some metaphysical entity that produces or is responsible for that regularity. | |
From: Bert Leuridan (Can Mechanisms Replace Laws of Nature? [2010], §1 n1) | |
A reaction: I take the second version to be a relic of a religious world view, and having no place in a naturalistic metaphysic. The regularity view is then the only player in the field, and the question is, can we do more? Can't we explain regularities? |
8197 | Maybe past (which affects us) and future (which we can affect) are both real [Dummett] |
Full Idea: Maybe both the past and the future are real, determined by our current temporal perspective. Past is then events capable of having a causal influence upon events near us, and future is events we can affect, but from which we receive no information. | |
From: Michael Dummett (Truth and the Past [2001], 5) | |
A reaction: This is the Four-Dimensional view, which is opposed to Presentism. Might immediate unease is that it gives encouragement to fortune-tellers, whom I have always dismissed with 'You can't see the future, because it doesn't exist'. |
8196 | The present cannot exist alone as a mere boundary; past and future truths are rendered meaningless [Dummett] |
Full Idea: The idea that only the present is real cannot be sustained. St Augustine pointed out that the present has no duration; it is a mere boundary between past and future, and dependent on them. It also denies truth-value to statements about past or future. | |
From: Michael Dummett (Truth and the Past [2001], 5) | |
A reaction: To defend Presentism, I suspect that one must focus entirely on the activities of consciousness and short-term memory. All truths, of past or future, must refer totally to such mental events. But what could an event be if there is no enduring time? |
5350 | The Hindu doctrine of reincarnation only appeared in the eighth century CE [Flanagan] |
Full Idea: The doctrine of a cycle of rebirths and reincarnations that are normally required before one achieve nirvana was only proposed in the eighth century CE, and then spread like wildfire among Hindus and, to a lesser extent, among Buddhists. | |
From: Owen Flanagan (The Problem of the Soul [2002], p.166n) | |
A reaction: Intriguing. Plato had proposed it in the fourth century BCE. Presumably Hindus had always been dualists, and then suddenly saw and exciting possibility that followed from it. The doctrine strikes me as (to put it mildly) implausible. |
5352 | The idea of the soul gets some support from the scientific belief in essential 'natural kinds' [Flanagan] |
Full Idea: The idea of the soul could be easily trashed if science does not countenance essences, but science does countenance essences in the form of what are known as 'natural kinds' (such as water, salt and gold). | |
From: Owen Flanagan (The Problem of the Soul [2002], p.181) | |
A reaction: The existence of any essences at all does indeed make the existence of a soul naturally possible, but scientific natural kinds are usually postulated on a basis of chemical stability. Animals, for example, are no longer usually classified that way. |
