| 18439 | Because things can share attributes, we cannot individuate attributes clearly [Quine] |
| Full Idea: No two classes have exactly the same members, but two different attributes may be attributes of exactly the same things. Classes are identical when their members are identical. ...On the other hand, attributes have no clear principle of individuation. | |
| From: Willard Quine (On the Individuation of Attributes [1975], p.100) |
| 18442 | You only know an attribute if you know what things have it [Quine] |
| Full Idea: May we not say that you know an attribute only insofar as you know what things have it? | |
| From: Willard Quine (On the Individuation of Attributes [1975], p.106) | |
| A reaction: Simple, and the best defence of class nominalism (a very implausible theory) which I have encountered. Do I have to know all the things? Do I not know 'red' if I don't know tomatoes have it? |
| 18441 | No entity without identity (which requires a principle of individuation) [Quine] |
| Full Idea: We have an acceptable notion of class, or physical object, or attribute, or any other sort of object, only insofar as we have an acceptable principle of individuation for that sort of object. There is no entity without identity. | |
| From: Willard Quine (On the Individuation of Attributes [1975], p.102) | |
| A reaction: Note that this is his criterion for an 'acceptable' notion. Presumably that is for science. It permits less acceptable notions which don't come up to the standard. And presumably true things can be said about the less acceptable entities. |
| 18440 | Identity of physical objects is just being coextensive [Quine] |
| Full Idea: Physical objects are identical if and only if coextensive. | |
| From: Willard Quine (On the Individuation of Attributes [1975], p.101) | |
| A reaction: The supposed counterexample to this is the statue and the clay it is made of, which are said to have different modal properties (destroying the statue doesn't destroy the clay). |
| 2590 | Dispositions need mental terms to define them [Putnam] |
| Full Idea: The chief difficulty with the behaviour-disposition account is the virtual impossibility of specifying a disposition except as a 'disposition of x to behave as though x were in pain'. | |
| From: Hilary Putnam (The Nature of Mental States [1968], p.57) | |
| A reaction: This has become the best-known objection to behaviourism - that you can't specify a piece of behaviour clearly unless you mention the mental state which it is expressing. The defence is to go on endlessly mentioning further behaviour. |
| 2591 | Total paralysis would mean that there were mental states but no behaviour at all [Putnam] |
| Full Idea: Two animals with all motor nerves cut will have the same actual and potential behaviour (i.e. none), but if only one has uncut pain fibres, it will feel pain where the other won't. | |
| From: Hilary Putnam (The Nature of Mental States [1968], p.57) | |
| A reaction: This is a splendidly literal and practical argument against behaviourism - if you prevent all the behaviour, you don't thereby prevent the experience. Clearly we have to say something about what is inside the 'black box' of the mind. |
| 2588 | Is pain a functional state of a complete organism? [Putnam] |
| Full Idea: I propose the hypothesis that pain, or the state of being in pain, is a functional state of a whole organism. | |
| From: Hilary Putnam (The Nature of Mental States [1968], p.54) | |
| A reaction: This sounds wrong right from the start. Pain hurts. The fact that it leads to avoidance behaviour etc. seems much more like a by-product of pain than its essence. |
| 2589 | Functionalism is compatible with dualism, as pure mind could perform the functions [Putnam] |
| Full Idea: The functional-state hypothesis is not incompatible with dualism, as a system consisting of a body and a soul could meet the required conditions. | |
| From: Hilary Putnam (The Nature of Mental States [1968], p.55) | |
| A reaction: He doesn't really believe this, of course. This claim led to all the weak objections to functionalism involving silly implementations of minds. A brain is the only plausible way to implement our mental functions. |
| 2592 | Functional states correlate with AND explain pain behaviour [Putnam] |
| Full Idea: The presence of a certain functional state is not merely 'correlated with' but actually explains the pain behaviour on the part of the organism. | |
| From: Hilary Putnam (The Nature of Mental States [1968], p.58) | |
| A reaction: Does it offer any further explanation beyond saying that it is the brain state that causes the behaviour? The pain is just a link between damage and avoidance. I wish that is all that pain was. |
| 2587 | Temperature is mean molecular kinetic energy, but they are two different concepts [Putnam] |
| Full Idea: The concept of temperature is not the same as the concept of mean molecular kinetic energy. But temperature is mean molecular kinetic energy. | |
| From: Hilary Putnam (The Nature of Mental States [1968], p.52) | |
| A reaction: This is the standard analogy for mind-brain identity, and it seems fair enough to me. The mind is the activity of the brain. It is rather unhelpful to think of weather in terms of chemistry, but it is actions of chemicals. |
| 6376 | Neuroscience does not support multiple realisability, and tends to support identity [Polger on Putnam] |
| Full Idea: Putnam was too quick to assert neuroscientific support for multiple realizability; current evidence does not reveal it, and there is some reason to think the enterprises of neuroscience are premised on the hypothesis of brain-state identity. | |
| From: comment on Hilary Putnam (The Nature of Mental States [1968]) by Thomas W. Polger - Natural Minds Ch.1.4 | |
| A reaction: I have always been suspicious of the glib claim that mental states were multiply realisable. I see no reason to think that octupi see colours as we do, or experience fear as we do, even though their behaviour has to be similar, for survival. |
| 2330 | If humans and molluscs both feel pain, it can't be a single biological state [Putnam, by Kim] |
| Full Idea: Mental states have vastly diverse physical/biological realizations in different species and structures (e.g. pain in humans and in molluscs), so no mental state can be identified with any single physical/biological state. | |
| From: report of Hilary Putnam (The Nature of Mental States [1968]) by Jaegwon Kim - Mind in a Physical World n p.120 | |
| A reaction: But maybe mollusc and human nervous systems ARE the same in the respects that matter. We don't know enough about pain to deny that possibility. |
| 6248 | Reason is too slow and doubtful to guide all actions, which need external and moral senses [Hutcheson] |
| Full Idea: We boast of our mighty reason above other animals, but its processes are too slow, too full of doubt, to serve us in every exigency, either for our preservation, without external senses, or to influence our actions for good without the moral sense. | |
| From: Francis Hutcheson (Treatise 2: Virtue or Moral Good [1725], §VII.III) | |
| A reaction: This idea was taken up by Hume, and it must have influence Hume's general scepticism about the importance of reason. What this idea misses is the enormous influence of prior reasoning on our quick decisions. |
| 6238 | We approve of actions by a superior moral sense [Hutcheson] |
| Full Idea: By a superior sense, which I call a moral one, we approve the actions of others. | |
| From: Francis Hutcheson (Treatise 2: Virtue or Moral Good [1725], Intro) | |
| A reaction: This tries to present moral insight as being on a par with the famous five senses. This doesn't seem quite right to me; separate parts of me can operate individual senses, but the whole of me is required for moral judgements, based on evidence. |
| 6239 | We dislike a traitor, even if they give us great benefit [Hutcheson] |
| Full Idea: Let us consider if a traitor, who would sell his own country to us, may not often be as advantageous to us, as an hero who defends us: and yet we can love the treason, and hate the traitor. | |
| From: Francis Hutcheson (Treatise 2: Virtue or Moral Good [1725], §I.VI) | |
| A reaction: A nice example, which certainly refutes any claim that morality is entirely and directly self-interested. High-minded idealism, though, is not the only alternative explanation. We admire loyalty, but not loyalty to, say, Hitler. |
| 6240 | The moral sense is not an innate idea, but an ability to approve or disapprove in a disinterested way [Hutcheson] |
| Full Idea: The moral sense is not an innate idea or knowledge, but a determination of our minds to receive the simple ideas of approbation or condemnation, from actions observed, antecedent to any opinions of advantage or loss to redound to ourselves. | |
| From: Francis Hutcheson (Treatise 2: Virtue or Moral Good [1725], §I.VIII) | |
| A reaction: This may claim a pure moral intuition, but it is also close to Kantian universalising of the rules for behaviour. It is also a variation on Descartes' 'natural light' of reason. Of course, if we say the ideas are 'received', where are they received from? |
| 6242 | We cannot choose our moral feelings, otherwise bribery could affect them [Hutcheson] |
| Full Idea: Neither benevolence nor any other affection or desire can be directly raised by volition; if they could, then we could be bribed into any affection whatsoever toward any object. | |
| From: Francis Hutcheson (Treatise 2: Virtue or Moral Good [1725], §II.IV) | |
| A reaction: Of course, notoriously, the vast mass of people have often been bribed to love a politician, by low taxes, or bread and circuses. Still, you cannot choose to love or admire someone, you just do. Not much free will there. |
| 6247 | Everyone feels uneasy when seeing others in pain, unless the others are evil [Hutcheson] |
| Full Idea: Every mortal is made uneasy by any grievous misery he sees another involved in, unless the person be imagined morally evil. | |
| From: Francis Hutcheson (Treatise 2: Virtue or Moral Good [1725], §V.VIII) | |
| A reaction: This is the natural compassion on which Hume built his moral theory. This remark emphasises that a concern for justice is just as important as a compassion for pain. Kant was more interested in what we deserve than in what we get. |
| 6244 | Human nature seems incapable of universal malice, except what results from self-love [Hutcheson] |
| Full Idea: Human nature seems scarce capable of malicious disinterested hatred, or an ultimate desire of the misery of others, when we imagine them not pernicious to us, or opposite to our interests; ..that is only the effect of self-love, not disinterested malice. | |
| From: Francis Hutcheson (Treatise 2: Virtue or Moral Good [1725], §II.VII) | |
| A reaction: I suppose it is true that even the worst criminals brooding in prison don't wish the entire population of some foreign country to die in pain. Only a very freakish person would wish the human race were extinct. A very nice observation. |
| 6243 | As death approaches, why do we still care about family, friends or country? [Hutcheson] |
| Full Idea: How comes it that we do not lose, at the approach of death, all concern for our families, friends, or country? | |
| From: Francis Hutcheson (Treatise 2: Virtue or Moral Good [1725], §II.V) | |
| A reaction: A nice question. No doubt some people do cease to care, but on the whole it raises the 'last round' problem in social contract theory, which is why fulfil your part of a bargain if it is too late to receive the repayment afterwards? |
| 6246 | My action is not made good by a good effect, if I did not foresee and intend it [Hutcheson] |
| Full Idea: No good effect, which I did not actually foresee and intend, makes my action morally good. | |
| From: Francis Hutcheson (Treatise 2: Virtue or Moral Good [1725], §III.XII) | |
| A reaction: This is one of the parents of utilitarianism repudiating pure consequentialism. Bentham sharply divided the action (which is consequentialist) from the person (who has useful intentions, but is not particulary important); this division is misleading. |
| 6241 | Contempt of danger is just madness if it is not in some worthy cause [Hutcheson] |
| Full Idea: Mere courage, or contempt of danger, if we conceive it to have no regard to the defence of the innocent, or repairing of wrongs or self-interest, would only entitle its possessor to bedlam. | |
| From: Francis Hutcheson (Treatise 2: Virtue or Moral Good [1725], §II.I) | |
| A reaction: If many criminals would love to rob a bank, but only a few have the nerve to attempt it, we can hardly deny that the latter exhibit a sort of courage. The Greeks say that good sense must be involved, but few of them were so moral about courage. |
| 6245 | That action is best, which procures the greatest happiness for the greatest number [Hutcheson] |
| Full Idea: That action is best, which procures the greatest happiness for the greatest number; and that worst, which, in like manner, occasions misery. | |
| From: Francis Hutcheson (Treatise 2: Virtue or Moral Good [1725], §III.VIII) | |
| A reaction: The first use of a phrase taken up by Bentham. This is not just an anticipation of utilitarianism, it is utilitarianism, with all its commitment to consequentialism (but see Idea 6246), and to the maximising of happiness. It is a brilliant idea. |
| 6251 | The loss of perfect rights causes misery, but the loss of imperfect rights reduces social good [Hutcheson] |
| Full Idea: Perfect rights are necessary to the public good, and it makes those miserable whose rights are thus violated; …imperfect rights tend to the improvement and increase of good in a society, but are not necessary to prevent universal misery. | |
| From: Francis Hutcheson (Treatise 2: Virtue or Moral Good [1725], §VII.VI) | |
| A reaction: This is a very utilitarian streak in Hutcheson, converting natural law into its tangible outcome in actual happiness or misery. The distinction here is interesting (taken up by Mill), but there is a very blurred borderline. |
| 6250 | We say God is good if we think everything he does aims at the happiness of his creatures [Hutcheson] |
| Full Idea: We call the Deity morally good, when we apprehend that his whole providence tends to the universal happiness of his creatures. | |
| From: Francis Hutcheson (Treatise 2: Virtue or Moral Good [1725], §VII.V) | |
| A reaction: From the point of view of eternity, we might accept that God aims at some even greater good than the happiness of a bunch of miserable little creatures whose bad behaviour merits little reward. The greater good needs to be impressive, though. |
| 6249 | If goodness is constituted by God's will, it is a tautology to say God's will is good [Hutcheson] |
| Full Idea: To call the laws of the supreme Deity good or holy or just, if these be constituted by laws, or the will of a superior, must be an insignificant tautology, amounting to no more than 'God wills what he wills' or 'His will is conformable to his will'. | |
| From: Francis Hutcheson (Treatise 2: Virtue or Moral Good [1725], §VII.V) | |
| A reaction: This argues not only against God as the source of morality, but also against any rules, such as those of the Categorical Imperative. Why should I follow the Categorical Imperative? What has value must dictate the rules. Is obedience the highest value? |
