3593 | The only way to specify the corresponding fact is asserting the sentence [Williams,M] |
Full Idea: The trouble with appeal to facts in the correspondence theory is that, in general, we have no way of indicating what fact a sentence, when true, corresponds to other than asserting the sentence. | |
From: Michael Williams (Problems of Knowledge [2001], Ch.12) |
3585 | Coherence needs positive links, not just absence of conflict [Williams,M] |
Full Idea: It is often claimed that coherence is more than 'absence of conflict' between beliefs; it also involves 'positive connections'. | |
From: Michael Williams (Problems of Knowledge [2001], Ch.10) |
3584 | Justification needs coherence, while truth might be ideal coherence [Williams,M] |
Full Idea: Contemporary coherence theorists are advancing a theory of justification, not of truth, …with those who argue that truth is also coherence explaining it in terms of ideal coherence, or coherence at the limit of enquiry. | |
From: Michael Williams (Problems of Knowledge [2001], Ch.10) |
3599 | Deduction shows entailments, not what to believe [Williams,M] |
Full Idea: The rules of deduction are rules of entailment, not rules of inference. They tell us what follows from what, not what to believe on the basis of what. | |
From: Michael Williams (Problems of Knowledge [2001], Ch.18) |
3591 | We could never pin down how many beliefs we have [Williams,M] |
Full Idea: Asking how many beliefs I have is like asking how many drops of water there are in a bucket. If I believe my dog is in the garden, do I also believe he is not in the house, or in Siberia? | |
From: Michael Williams (Problems of Knowledge [2001], Ch.11) |
3582 | Propositions make error possible, so basic experiential knowledge is impossible [Williams,M] |
Full Idea: Propositional content is inseparable from possible error. Therefore no judgement, however modest, is indubitable. So if basic experiential knowledge has to be indubitable, there is no such knowledge. | |
From: Michael Williams (Problems of Knowledge [2001], Ch. 8) |
3592 | Phenomenalism is a form of idealism [Williams,M] |
Full Idea: Phenomenalism is a form of idealism. | |
From: Michael Williams (Problems of Knowledge [2001], Ch.12) |
3579 | Sense data avoid the danger of misrepresenting the world [Williams,M] |
Full Idea: The point of insisting on the absolute immediacy of sense data is that representation always seems to involve the possibility of misrepresentation. | |
From: Michael Williams (Problems of Knowledge [2001], Ch. 8) |
3581 | Sense data can't give us knowledge if they are non-propositional [Williams,M] |
Full Idea: Acquaintance with sense data is supposed to be a form of non-propositional knowledge, but how can something be non-propositional and yet knowledge? | |
From: Michael Williams (Problems of Knowledge [2001], Ch. 8) |
3564 | Is it people who are justified, or propositions? [Williams,M] |
Full Idea: What exactly is supposed to be 'justified': a person's believing some particular proposition, or the proposition that he believes? | |
From: Michael Williams (Problems of Knowledge [2001], Ch. 1) | |
A reaction: A key distinction. See my comment on Idea 3752. What would justify a sign saying 'treasure buried here'? People can be justified in believing falsehoods. How could a false proposition be justified? |
8851 | Coherentists say that regress problems are assuming 'linear' justification [Williams,M] |
Full Idea: From the point of view of the coherentist, Agrippa's Dilemma fails because it presupposes a 'linear' conception of justifying inference. | |
From: Michael Williams (Without Immediate Justification [2005], §2) | |
A reaction: [He cites Bonjour 1985 for this view] Since a belief may have several justifications, and one belief could justify a host of others, there certainly isn't a simple line of justifications. I agree with the coherentist picture here. |
3595 | What works always takes precedence over theories [Williams,M] |
Full Idea: A theory that represents working practices as unworkable is a bad theory. | |
From: Michael Williams (Problems of Knowledge [2001], Ch.13) | |
A reaction: Good point. There's a lot of this about in epistemology, especially accusations of circularity or infinite regress, which (if true) don't somehow seem to worry the cove on the Clapham omnibus. |
8849 | Traditional foundationalism is radically internalist [Williams,M] |
Full Idea: Traditional foundationalism is radically internalist. The justification-making factors for beliefs, basic and otherwise, are all open to view, and perhaps even actual objects of awareness. I am always in a position to know that I know. | |
From: Michael Williams (Without Immediate Justification [2005], §1) | |
A reaction: This is a helpful if one is trying to draw a map of the debate. An externalist foundationalism would have to terminate in the external fact which was the object of knowledge (via some reliable channel), but that is the truth, not the justification. |
3580 | Experience must be meaningful to act as foundations [Williams,M] |
Full Idea: If we are to treat experience as the foundation of knowledge, then experience must itself be understood to involve propositional content. | |
From: Michael Williams (Problems of Knowledge [2001], Ch. 8) | |
A reaction: This sounds right, but since pure 'experience' obviously doesn't have propositional content, because it needs interpretation and evaluation, then this strategy won't work. |
8853 | Basic judgements are immune from error because they have no content [Williams,M] |
Full Idea: Basic judgements threaten to buy their immunity from error at the cost of being drained of descriptive content altogether. | |
From: Michael Williams (Without Immediate Justification [2005], §4) | |
A reaction: This is probably the key objection to foundationalism. As you import sufficient content into basic experiences to enable them to actually justify a set of beliefs, you find you have imported all sorts of comparisons and classifications as well. |
3578 | Are empirical foundations judgements or experiences? [Williams,M] |
Full Idea: Empirical foundationists must decide whether knowledge ultimately rests on either beliefs or judgements about experience, or on the experiences or sensations themselves. | |
From: Michael Williams (Problems of Knowledge [2001], Ch. 8) | |
A reaction: This clarifies the key issue very nicely, and I firmly vote for the former option. The simplest point is that error is possible about what sensations are taken to be of, so they won't do on their own. |
8855 | Sensory experience may be fixed, but it can still be misdescribed [Williams,M] |
Full Idea: The fact that experiential contents cannot be other than they are, as far as sensory awareness goes, does not imply that we cannot misdescribe them, as in misreporting the number of speckles on a speckled hen (Chisholm's example). | |
From: Michael Williams (Without Immediate Justification [2005], §4) | |
A reaction: [Chisholm 1942 is cited] Such experiences couldn't be basic beliefs if there was a conflict between their intrinsic nature and the description I used in discussing them. |
3576 | Foundationalists are torn between adequacy and security [Williams,M] |
Full Idea: The foundationalists dilemma is to define a basis for knowledge modest enough to be secure but rich enough to be adequate. | |
From: Michael Williams (Problems of Knowledge [2001], Ch. 7) | |
A reaction: ..And that is just what they are unable to do, precisely because adequate support would have to have enough content to be defeasibe or fallible. |
3577 | Strong justification eliminates error, but also reduces our true beliefs [Williams,M] |
Full Idea: A strongly justificationist view of rationality may not be so rational; we want the truth, but avoiding all errors and maximising our number of true beliefs are not the same thing. | |
From: Michael Williams (Problems of Knowledge [2001], Ch. 7) | |
A reaction: An interesting dilemma - to avoid all errors, believing nothing; to maximise true belief, believe everything. It is rational to follow intuition, guesses, and a wing and a prayer - once you are experienced and educated. |
3589 | Why should diverse parts of our knowledge be connected? [Williams,M] |
Full Idea: Why should political theory ever have much to do with quantum physics, or pet care with parliamentary history? | |
From: Michael Williams (Problems of Knowledge [2001], Ch.11) | |
A reaction: This hardly demolishes the coherence account of justification, since your views on pet care had better be coherent, for your pet's sake. It's a pity people can make their politics cohere with their ethics. |
3590 | Coherence theory must give a foundational status to coherence itself [Williams,M] |
Full Idea: Coherence theory implicitly assigns the criteria of coherence a special status. …In so far as this status is assigned a priori, the coherence theory represents a rationalistic variant of foundationalism. | |
From: Michael Williams (Problems of Knowledge [2001], Ch.11) | |
A reaction: Nice move, to accuse coherence theorists of foundationalism! Wrong, though, because the a priori principles of coherence are not basic beliefs, but evolved pragmatic procedures (or something...). |
3571 | Externalism does not require knowing that you know [Williams,M] |
Full Idea: From an externalist point of view, knowing about one's reliability is not required for 'first-order' knowledge. | |
From: Michael Williams (Problems of Knowledge [2001], Ch. 2) | |
A reaction: Ah. 'First-order knowledge' - what's that? What we used to call 'true belief', I would say. Adequate for animals, and a good guide to daily life, but uncritical and unjustifiable. |
3574 | Externalism ignores the social aspect of knowledge [Williams,M] |
Full Idea: A problem with pure externalism is that it ignores the social dimension of knowledge. | |
From: Michael Williams (Problems of Knowledge [2001], Ch. 2) | |
A reaction: This seems to be contradicted by Idea 3573, which allows a social dimension to agreement over what is reliable. I am inclined to take knowledge as an entirely social concept. |
3569 | In the causal theory of knowledge the facts must cause the belief [Williams,M] |
Full Idea: According to Goldman's early causal theory of knowledge, my belief that p counts as knowledge if and only if it is caused by the fact that p. This is sufficient as well as necessary, and so does not involve justification. | |
From: Michael Williams (Problems of Knowledge [2001], Ch. 2) | |
A reaction: I take his theory simply to be false because what causes a belief is not what justifies it. I expect my mother to ring; the phone rings; I 'know' it is my mother (and it is), because I strongly expect it. |
3567 | How could there be causal relations to mathematical facts? [Williams,M] |
Full Idea: It is not clear what would even be meant by supposing that there are causal relations to mathematical facts. | |
From: Michael Williams (Problems of Knowledge [2001], Ch. 2) | |
A reaction: I agree, though platonists seem to be willing to entertain the possibility that there are causal relations, for which no further explanation can be given. Better is knowledge without a causal relation. |
3586 | Only a belief can justify a belief [Williams,M] |
Full Idea: Justification requires logical rather than causal connections. That is the point of the slogan that only a belief can justify a belief. | |
From: Michael Williams (Problems of Knowledge [2001], Ch.10) | |
A reaction: It seems better to talk of 'rational' connections, rather than 'logical' connections. It isn't 'logical' to believe that someone despises me because their lip is faintly curled. |
3573 | Externalist reliability refers to a range of conventional conditions [Williams,M] |
Full Idea: The radical externalists' key notion is 'reliability', which is a normative condition governing adequate performance, involving reference to a range of conditions which we decide rather than discover. | |
From: Michael Williams (Problems of Knowledge [2001], Ch. 2) | |
A reaction: If we can decide whether a source is reliable, we can also decide whether a reliable source has performed well on this occasion, and that will always take precedence. |
3565 | Sometimes I ought to distrust sources which are actually reliable [Williams,M] |
Full Idea: I may reach a belief using a procedure that is in fact reliable, but which I ought to distrust. | |
From: Michael Williams (Problems of Knowledge [2001], Ch. 1) | |
A reaction: The tramp on the park bench who gives good share tips. The clock that is finally working, but has been going haywire for weeks. Reliabilism is a bad theory. |
3566 | We control our beliefs by virtue of how we enquire [Williams,M] |
Full Idea: We control our beliefs by virtue of how we enquire. | |
From: Michael Williams (Problems of Knowledge [2001], Ch. 1) |
8852 | In the context of scepticism, externalism does not seem to be an option [Williams,M] |
Full Idea: In the peculiar context of the skeptical challenge, it is easy to persuade oneself that externalism is not an option. | |
From: Michael Williams (Without Immediate Justification [2005], §3) | |
A reaction: This is because externalism sees justification as largely non-conscious, but when faced with scepticism, the justifications need to be spelled out, and therefore internalised. So are sceptical discussions basic, or freakish anomalies? |
3594 | Scepticism just reveals our limited ability to explain things [Williams,M] |
Full Idea: All the sceptic's arguments show is that there are limits to our capacity to give reasons or cite evidence. | |
From: Michael Williams (Problems of Knowledge [2001], Ch.13) |
3575 | Scepticism can involve discrepancy, relativity, infinity, assumption and circularity [Williams,M] |
Full Idea: The classical Five Modes of Scepticism are Discrepancy (people always disagree), Relativity ('according to you'), Infinity (infinite regress of questions), Assumption (ending in dogma) and Circularity (end up where you started). | |
From: Michael Williams (Problems of Knowledge [2001], Ch. 5) | |
A reaction: I take Relativity to be different from scepticism (because, roughly, it says there is nothing to know), and the others go with Agrippa's Trilemma of justification, which may have solutions. |
3587 | Seeing electrons in a cloud chamber requires theory [Williams,M] |
Full Idea: Armed with enough theory, we can see electrons in a cloud chamber. | |
From: Michael Williams (Problems of Knowledge [2001], Ch.10) |
3588 | Foundationalists base meaning in words, coherentists base it in sentences [Williams,M] |
Full Idea: In the foundationalist picture the meaning of individual words (defined ostensively) is primary, and that of sentences is derivative. For coherentists sentences come first, with meaning understood functionally or inferentially. | |
From: Michael Williams (Problems of Knowledge [2001], Ch.10) | |
A reaction: Coherentism about language doesn't imply coherentism about justification. On language I vote for foundationalism, because I am impressed by the phenomenon of compositionality. |
20289 | Ethics is universalisable - it must involve an impartial and universal view of things [Singer] |
Full Idea: A distinguishng feature of ethics is that ethical judgements are universalisable. Ethics requires us to go beyond our own personal point of view to a standpoint like that of the impartial spectator who takes a universal point of view. | |
From: Peter Singer (Practical Ethics [1979], 10) | |
A reaction: I'm thinking that ethical agents are more 'situated' than that. Suppose a finance minister stole billions in tax and gave it to a poor country. Good from the universal angle, perhaps, but a shocking betrayal of his own community. |
20286 | Following an inner voice for morality is irresponsible in a rational agent [Singer] |
Full Idea: When following conscience means doing as one's 'internal voice' prompts one to do, to follow one's conscience it so abdicate one's responsibility as a rational agent. | |
From: Peter Singer (Practical Ethics [1979], 09) | |
A reaction: Seems dead right. An inner voice is far more likely to be your culture and upbringing than to be an absolute moral truth. It may not be entirely wrong, though, to behave as your culture requires. |
20282 | The sanctity of a human life depends either on being of our species, or on being a person [Singer] |
Full Idea: The doctrine of the sanctity of human life has two separate claims, one that there is a special value in the life of a member of our species, and the other that there is a special value in the life of a person. | |
From: Peter Singer (Practical Ethics [1979], 04) |
20278 | 'Marginal utility' says something is more useful if it is in short supply [Singer] |
Full Idea: The economic principle of marginal utility states that for a given individual a set amount of something is more useful when the individual has little of it than when he has a lot. | |
From: Peter Singer (Practical Ethics [1979], 02) | |
A reaction: But individuals may very a lot on this one. 'He can't get enough of X'. I may be desperate to buy 10,000 books, but you may consider such a need ridiculous, so who decides? |
20281 | Why should I do anything for posterity? What has posterity ever done for me? [Singer] |
Full Idea: Most striking is the impact of the contract model on our attitude to future generations. 'Why should I do anything for posterity? What has posterity ever done for me?' would be the view we ought to take. | |
From: Peter Singer (Practical Ethics [1979], 03) | |
A reaction: I should bury my mobile phone for future archaeologists, because it will be more valuable then than it is now. Singer cites the disposal of nuclear waste as an instance. |
20276 | Conflict of rules might be avoided by greater complexity, or by a hierarchy of rules [Singer] |
Full Idea: Those who think ethics is a system of rules can rescue their position by finding more complicated and more specific rules which do not conflict, or by ranking the rules in some hierarchical structure to resolve conflicts. | |
From: Peter Singer (Practical Ethics [1979], 01) | |
A reaction: The problem is that clear-cut rules seem to produce conflicts. I would have thought that more specific rules would increase that problem. Safety is in generality. |
20290 | Psychopaths may just be bored, because they cannot participate in normal emotional life [Singer] |
Full Idea: Maybe psychopaths are bored because their emotional poverty means that they cannot take interest in, or gain satisfaction from, what for others are the most important things in life: love, family, success in business or professional life, etc. | |
From: Peter Singer (Practical Ethics [1979], 10) | |
A reaction: [he cites Hervey Cleckley for this] Maybe boredom is a symptom of some human inadequacy, but it might sometimes be a mark of superiority. It drives people to both creation and destruction. Quite a good account of criminal behaviour. |
20288 | You can't condemn violent revolution without assessing the evils it prevents [Singer] |
Full Idea: It would be one-sided to say that violent revolution is always absolutely wrong, without taking account of the evils that the revolutionaries are trying to stop. | |
From: Peter Singer (Practical Ethics [1979], 09) | |
A reaction: This seems like common sense, but there are plenty of right-wing authoritarians who would claim that stable authority has priority over all social wrongs. I think that view is mistaken. But the problem is, how to know the future? |
21997 | In Marxism the state will be superseded [Singer] |
Full Idea: It is a famous Marxist doctrine that the state will be superseded. | |
From: Peter Singer (Marx [1980], 9) | |
A reaction: Why is that final state communism rather than anarchism? |
20287 | If 49% of the population can be wrong, so can 51% [Singer] |
Full Idea: The case for majority rule should not be overstated. No sensible democrat would claim that the majority is always right. If 49% of the population can be wrong, so can 51%. | |
From: Peter Singer (Practical Ethics [1979], 09) | |
A reaction: Well said! We can't possibly put a figure on when the majority become right. In the recent Brexit referendum hardly anyone seemed to understand the issues very well, so none of us have a clue about who was right. |
21993 | Materialist history says we are subject to incomprehensible forces [Singer] |
Full Idea: The materialist conception of history tells us that human beings are totally subject to forces they do not understand and control. | |
From: Peter Singer (Marx [1980], 6) | |
A reaction: How does Marx know the forces? An exceptionally influential idea, because it is a modern commonplace that we have very little control over our own lives (apart from right wingers asserting that 'you can have anything if you really really want it'). |
20277 | Equality of interests is a minimal principle, not implying equal treatment [Singer] |
Full Idea: Equal consideration of interests is a minimal principle of equality in the sense that it does not dictate equal treatment. | |
From: Peter Singer (Practical Ethics [1979], 02) | |
A reaction: Do those convicted of serious crime retain equal interests? Should a huge group of people sacrifice all of their interests, because of the powerful interests of one person? |
20279 | Equality of opportunity unfairly rewards those lucky enough to have great ability [Singer] |
Full Idea: Equality of opportunity is not an attractive ideal. It rewards the lucky, who inherit those abilities that allow them to pursue interesting and lucrative careers. | |
From: Peter Singer (Practical Ethics [1979], 02) | |
A reaction: He makes it sound like cheating. Singer has a highly individualistic view, but society as a whole needs the development of talent, wherever it can be found. |
20285 | If a right entails having the relevant desire, many creatures might have no right to life [Singer] |
Full Idea: If to have a right one must have the ability to desire that to which one has a right, then to have a right to life one must be able to desire one's own continued existence. | |
From: Peter Singer (Practical Ethics [1979], 07) | |
A reaction: The unborn, small infants, and persons in comas may well lack the relevant desire (at least consciously - arguably even a plant has a non-conscious 'desire' or drive for life). The idea that a right entails a conscious desire seems daft. |
20284 | Why should a potential person have the rights of an actual person? [Singer] |
Full Idea: A prince may be a potential king, but he does not have the rights of a king. Why should a potential person have the rights of a person? | |
From: Peter Singer (Practical Ethics [1979], 06) | |
A reaction: But the prince is probably accorded special rights, merely on the grounds that he is the potential king. An unborn potential king is always considered as special. |
20283 | Killing a chimp is worse than killing a human too defective to be a person [Singer] |
Full Idea: It seems that killing a chimpanzee is worse than the killing of a gravely defective human who is not a person. ...[p.103] the effects on relatives of the defective human will sometimes constitute additional indirect reasons against killing the human. | |
From: Peter Singer (Practical Ethics [1979], 05) | |
A reaction: Singer's most notorious idea. Perhaps we should all carry cards (perhaps combined with donor cards) saying how many people will care if we die. |
20698 | Irenaeus says evil is necessary for perfect human development [Irenaeus, by Davies,B] |
Full Idea: Echoing Irenaeus, John Hick argues that the existence of evil is necessary for the perfect development of human beings. Hick understands evil in the light of God's desire not to coerce people into accepting him. | |
From: report of Irenaeus (works [c.190]) by Brian Davies - Introduction to the Philosophy of Religion 3 'Notable' | |
A reaction: I don't suppose I could opt out of perfect development? If I endure the evil, can I be guaranteed that my development will be 'perfect'. Oh, and could I just check what is meant by 'development'? |
