9184 | We can't presume that all interesting concepts can be analysed [Williamson] |
Full Idea: We have no prior reason to suppose that philosophically significant concepts have interesting analyses into necessary and sufficient conditions. | |
From: Timothy Williamson (Review of Bob Hale's 'Abstract Objects' [1988]) | |
A reaction: We might think that they are either analysable or primitive, and that failure of analysis invites us to take a concept as primitive. But maybe God can analyse it and we can't. |
9183 | Platonism claims that some true assertions have singular terms denoting abstractions, so abstractions exist [Williamson] |
Full Idea: The Fregean argument for platonism is that some true assertions contain singular terms which denote abstract objects if they denote anything; since the assertions are true, the singular terms denote. | |
From: Timothy Williamson (Review of Bob Hale's 'Abstract Objects' [1988]) | |
A reaction: I am perplexed that anyone would rest their view of reality on such an argument. The obvious comparison would be with true remarks about blatantly fictional characters, or blatantly invented concepts such as 'checkmate'. |
9476 | If dispositions are more fundamental than causes, then they won't conceptually reduce to them [Bird on Lewis] |
Full Idea: Maybe a disposition is a more fundamental notion than a cause, in which case Lewis has from the very start erred in seeking a causal analysis, in a traditional, conceptual sense, of disposition terms. | |
From: comment on David Lewis (Causation [1973]) by Alexander Bird - Nature's Metaphysics 2.2.8 | |
A reaction: Is this right about Lewis? I see him as reducing both dispositions and causes to a set of bald facts, which exist in possible and actual worlds. Conditionals and counterfactuals also suffer the same fate. |
8425 | For true counterfactuals, both antecedent and consequent true is closest to actuality [Lewis] |
Full Idea: A counterfactual is non-vacuously true iff it takes less of a departure from actuality to make the consequent true along with the antecedent than it does to make the antecedent true without the consequent. | |
From: David Lewis (Causation [1973], p.197) | |
A reaction: Almost every theory proposed by Lewis hangs on the meaning of the word 'close', as used here. If you visited twenty Earth-like worlds (watch Startrek?), it would be a struggle to decide their closeness to ours in rank order. |
8424 | Determinism says there can't be two identical worlds up to a time, with identical laws, which then differ [Lewis] |
Full Idea: By determinism I mean that the prevailing laws of nature are such that there do not exist any two possible worlds which are exactly alike up to that time, which differ thereafter, and in which those laws are never violated. | |
From: David Lewis (Causation [1973], p.196) | |
A reaction: This would mean that the only way an action of free will could creep in would be if it accepted being a 'violation' of the laws of nature. Fans of free will would probably prefer to call it a 'natural' phenomenon. I'm with Lewis. |
8420 | A proposition is a set of possible worlds where it is true [Lewis] |
Full Idea: I identify a proposition with the set of possible worlds where it is true. | |
From: David Lewis (Causation [1973], p.193) | |
A reaction: As it stands, I'm baffled by this. How can 'it is raining' be a set of possible worlds? I assume it expands to refer to the truth-conditions, among possibilities as well as actualities. 'It is raining' fits all worlds where it is raining. |
3772 | The will, in the beginning, is entirely produced by desire [Mill] |
Full Idea: The will, in the beginning, is entirely produced by desire. | |
From: John Stuart Mill (Utilitarianism [1861], Ch.4) | |
A reaction: This is the sort of simplistic psychology that modern philosophers tend to avoid. Personally I am more Kantian. I will and desire that the answer to 3+2=? is 5, simply because it is true. Mill must realise we can will ourselves to desire something. |
3769 | With early training, any absurdity or evil may be given the power of conscience [Mill] |
Full Idea: There is hardly anything so absurd or so mischievous that it may not, by means of early sanctions and influence, be made to act on the human mind with all the influence of conscience. | |
From: John Stuart Mill (Utilitarianism [1861], Ch.3) | |
A reaction: Like this! Think of all the people who have had weird upbringings, and end up feeling guilty about absurd things. Conscience just summarise upbringing and social conventions. |
3767 | Motive shows the worth of the agent, but not of the action [Mill] |
Full Idea: The motive has nothing to do with the morality of the action, though much with the worth of the agent. | |
From: John Stuart Mill (Utilitarianism [1861], Ch.2) | |
A reaction: I think it is an error to try to separate these too sharply. Morality can't be purely consequential, because it would make earthquakes immoral. Actions indicate the worth of agents. |
3771 | Virtues only have value because they achieve some further end [Mill] |
Full Idea: Utilitarians believe that actions and dispositions are only virtuous because they promote another end than virtue. | |
From: John Stuart Mill (Utilitarianism [1861], Ch.4) |
3768 | Orthodox morality is the only one which feels obligatory [Mill] |
Full Idea: The customary morality, that which education and opinion have consecrated, is the only one which presents itself to the mind with the feeling of being in itself obligatory. | |
From: John Stuart Mill (Utilitarianism [1861], Ch.3) |
3776 | Utilitarianism only works if everybody has a totally equal right to happiness [Mill] |
Full Idea: The Greatest Happiness Principle is a mere form of empty words unless one person's happiness, supposed equal in degree, is counted for exactly as much as another's (Bentham's "everybody to count for one, nobody for more than one"). | |
From: John Stuart Mill (Utilitarianism [1861], Ch.5) |
7202 | The English believe in the task of annihilating evil for the victory of good [Nietzsche on Mill] |
Full Idea: One continues to believe in good and evil: in such a way that one feels the victory of good and the annihilation of evil to be a task (- this is English; a typical case is that shallow-headed John Stuart Mill). | |
From: comment on John Stuart Mill (Utilitarianism [1861]) by Friedrich Nietzsche - Writings from Late Notebooks 11[148]e | |
A reaction: The poor old English try very hard to be clear, sensible, practical and realistic, and get branded as 'shallow' for their pains. Nietzsche was a deeper thinker than Mill, but I would prefer Mill to Heidegger any day. |
5935 | Mill's qualities of pleasure is an admission that there are other good states of mind than pleasure [Ross on Mill] |
Full Idea: Mill's introduction of quality of pleasures into the hedonistic calculus is an unconscious departure from hedonism and a half-hearted admission that there are other qualities than pleasantness in virtue of which states of mind are good. | |
From: comment on John Stuart Mill (Utilitarianism [1861], Ch.2) by W. David Ross - The Right and the Good §VI | |
A reaction: Mill argues that experienced people prefer some pleasures to others, but ducks the question of why they might prefer them. It can only be because they have some further desirable quality on top of the equal amount of pleasure. |
3764 | Actions are right if they promote pleasure, wrong if they promote pain [Mill] |
Full Idea: The Greatest Happiness Principle holds that actions are right in proportion as they tend to promote happiness, wrong as they tend to produce the reverse of happiness. By happiness is intended pleasure, and the absence of pain. | |
From: John Stuart Mill (Utilitarianism [1861], Ch.2) |
3766 | Better to be Socrates dissatisfied than a fool satisfied [Mill] |
Full Idea: Better to be Socrates dissatisfied than a fool satisfied. | |
From: John Stuart Mill (Utilitarianism [1861], Ch.2) |
3763 | Ultimate goods such as pleasure can never be proved to be good [Mill] |
Full Idea: What can be proved good must be so by being shown to be a means to something admitted to be good without proof. Music is good because it produces pleasure, but what proof is it possible to give that pleasure is good? | |
From: John Stuart Mill (Utilitarianism [1861], Ch.1) |
3765 | Only pleasure and freedom from pain are desirable as ends [Mill] |
Full Idea: Pleasure and freedom from pain are the only things desirable as ends. | |
From: John Stuart Mill (Utilitarianism [1861], Ch.2) |
3770 | General happiness is only desirable because individuals desire their own happiness [Mill] |
Full Idea: No reason can be given why the general happiness is desirable, except that each person, so far as he believes it to be attainable, desires his own happiness. | |
From: John Stuart Mill (Utilitarianism [1861], Ch.4) |
6697 | Moral rules protecting human welfare are more vital than local maxims [Mill] |
Full Idea: Moral rules which forbid mankind to hurt one another are more vital to human well-being than any maxims about some department of human affairs; ..though in particular cases a social duty is so important, as to overrule any general maxim of justice. | |
From: John Stuart Mill (Utilitarianism [1861]), quoted by Gordon Graham - Eight Theories of Ethics Ch.7 | |
A reaction: The qualification is realistic, but raises the question of whether an 'act' calculation will always overrule any 'rule'. Maybe rule utilitirianism is just act utilitarianism, but ensuring that the calculations are long-term and extensive. (1871 edn) |
3774 | Rights are a matter of justice, not of benevolence [Mill] |
Full Idea: Wherever there is a right, the case is one of justice, and not of the virtue of benevolence. | |
From: John Stuart Mill (Utilitarianism [1861], Ch.5) |
3773 | No individual has the right to receive our benevolence [Mill] |
Full Idea: No one has a moral right to our generosity or beneficence, because we are not morally bound to practise those virtues towards any given individual. | |
From: John Stuart Mill (Utilitarianism [1861], Ch.5) |
3775 | A right is a valid claim to society's protection [Mill] |
Full Idea: When we call anything a person's right, we mean that he has a valid claim on society to protect him in the possession of it. | |
From: John Stuart Mill (Utilitarianism [1861], Ch.5) |
8405 | A theory of causation should explain why cause precedes effect, not take it for granted [Lewis, by Field,H] |
Full Idea: Lewis thinks it is a major defect in a theory of causation that it builds in the condition that the time of the cause precede that of the effect: that cause precedes effect is something we ought to explain (which his counterfactual theory claims to do). | |
From: report of David Lewis (Causation [1973]) by Hartry Field - Causation in a Physical World | |
A reaction: My immediate reaction is that the chances of explaining such a thing are probably nil, and that we might as well just accept the direction of causation as a given. Even philosophers balk at the question 'why doesn't time go backwards?' |
8427 | I reject making the direction of causation axiomatic, since that takes too much for granted [Lewis] |
Full Idea: One might stipulate that a cause must always precede its effect, but I reject this solution. It won't solve the problem of epiphenomena, it rejects a priori any backwards causation, and it trivializes defining time-direction through causation. | |
From: David Lewis (Causation [1973], p.203) | |
A reaction: [compressed] Not strong arguments, I would say. Maybe apparent causes are never epiphenomenal. Maybe backwards causation is impossible. Maybe we must use time to define causal direction, and not vice versa. |
10392 | It is just individious discrimination to pick out one cause and label it as 'the' cause [Lewis] |
Full Idea: We sometimes single out one among all the causes of some event and call it 'the' cause. ..We may select the abnormal causes, or those under human control, or those we deem good or bad, or those we want to talk about. This is invidious discrimination. | |
From: David Lewis (Causation [1973]) | |
A reaction: This is the standard view expressed by Mill - presumably the obvious empiricist line. But if we specify 'the pre-conditions' for an event, we can't just mention ANY fact prior to the effect - there is obvious relevance. So why not for 'the' cause as well? |
8419 | The modern regularity view says a cause is a member of a minimal set of sufficient conditions [Lewis] |
Full Idea: In present-day regularity analyses, a cause is defined (roughly) as any member of any minimal set of actual conditions that are jointly sufficient, given the laws, for the existence of the effect. | |
From: David Lewis (Causation [1973], p.193) | |
A reaction: This is the view Lewis is about to reject. It seem to summarise the essence of the Mackie INUS theory. This account would make the presence of oxygen a cause of almost every human event. |
8421 | Regularity analyses could make c an effect of e, or an epiphenomenon, or inefficacious, or pre-empted [Lewis] |
Full Idea: In the regularity analysis of causes, instead of c causing e, c might turn out to be an effect of e, or an epiphenomenon, or an inefficacious effect of a genuine cause, or a pre-empted cause (by some other cause) of e. | |
From: David Lewis (Causation [1973], p.194) | |
A reaction: These are Lewis's reasons for rejecting the general regularity account, in favour of his own particular counterfactual account. It is unlikely that c would be regularly pre-empted or epiphenomenal. If we build time's direction in, it won't be an effect. |
17525 | The counterfactual view says causes are necessary (rather than sufficient) for their effects [Lewis, by Bird] |
Full Idea: The Humean idea, developed by Lewis, is that rather than being sufficient for their effects, causes are (counterfactual) necessary for their effects. | |
From: report of David Lewis (Causation [1973]) by Alexander Bird - Causation and the Manifestation of Powers p.162 |
17524 | Lewis has basic causation, counterfactuals, and a general ancestral (thus handling pre-emption) [Lewis, by Bird] |
Full Idea: Lewis's basic account has a basic causal relation, counterfactual dependence, and the general causal relation is the ancestral of this basic one. ...This is motivated by counterfactual dependence failing to be general because of the pre-emption problem. | |
From: report of David Lewis (Causation [1973]) by Alexander Bird - Causation and the Manifestation of Powers p.161 | |
A reaction: It is so nice when you struggle for ages with a topic, and then some clever person summarises it clearly for you. |
8397 | Counterfactual causation implies all laws are causal, which they aren't [Tooley on Lewis] |
Full Idea: Some counterfactuals are based on non-causal laws, such as Newton's Third Law of Motion. 'If no force one way, then no force the other'. Lewis's counterfactual analysis implies that one force causes the other, which is not the case. | |
From: comment on David Lewis (Causation [1973]) by Michael Tooley - Causation and Supervenience 5.2 | |
A reaction: So what exactly does 'cause' my punt to move forwards? Basing causal laws on counterfactual claims looks to me like putting the cart before the horse. |
8423 | My counterfactual analysis applies to particular cases, not generalisations [Lewis] |
Full Idea: My (counterfactual) analysis is meant to apply to causation in particular cases; it is not an analysis of causal generalizations. Those presumably quantify over particulars, but it is hard to match natural language to the quantifiers. | |
From: David Lewis (Causation [1973], p.195) | |
A reaction: What authority could you have for asserting a counterfactual claim, if you only had one observation? Isn't the counterfactual claim the hallmark of a generalisation? For one case, 'if not-c, then not-e' is just a speculation. |
8426 | One event causes another iff there is a causal chain from first to second [Lewis] |
Full Idea: One event is the cause of another iff there exists a causal chain leading from the first to the second. | |
From: David Lewis (Causation [1973], p.200) | |
A reaction: It will be necessary to both explain and identify a 'chain'. Some chains are extremely tenuous (Alexander could stop a barrel of beer). Go back a hundred years, and the cause of any present event is everything back then. |
4795 | Lewis's account of counterfactuals is fine if we know what a law of nature is, but it won't explain the latter [Cohen,LJ on Lewis] |
Full Idea: Lewis can elucidate the logic of counterfactuals on the assumption that you are not at all puzzled about what a law of nature is. But if you are puzzled about this, it cannot contribute anything towards resolving your puzzlement. | |
From: comment on David Lewis (Causation [1973]) by L. Jonathan Cohen - The Problem of Natural Laws p.219 | |
A reaction: This seems like a penetrating remark. The counterfactual theory is wrong, partly because it is epistemological instead of ontological, and partly because it refuses to face the really difficult problem, of what is going on out there. |
