101 ideas
| 23350 | A wise philosophers uses reason to cautiously judge each aspect of living [Epictetus] |
| Full Idea: The sinews of a philosopher are desire that never fails in its achievement; aversion that never meets with what it would avoid; appropriate impulse; carefully considered purpose; and assent that is never precipitate. | |
| From: Epictetus (The Discourses [c.56], 2.08.29) | |
| A reaction: This is a very individual view of wisdom and the philosopher, whereas wisdom is often thought to have a social role. Is it not important for a philosopher to at least offer advice? |
| 23355 | The task of philosophy is to establish standards, as occurs with weights and measures [Epictetus] |
| Full Idea: Things are judged and weighed, when we have the standards ready. This is the task of philosophy: to examine and establish the standards. | |
| From: Epictetus (The Discourses [c.56], 2.11.24) | |
| A reaction: It is interesting that this gives philosophers a very specific social role, and also that it seems to identify epistemology as First Philosophy. Other disciplines, of course, establish their own standards without reference to philosophy. |
| 23367 | Even pointing a finger should only be done for a reason [Epictetus] |
| Full Idea: Philosophy says it is not right even to stretch out a finger without some reason. | |
| From: Epictetus (fragments/reports [c.57], 15) | |
| A reaction: The key point here is that philosophy concerns action, an idea on which Epictetus is very keen. He rather despise theory. This idea perfectly sums up the concept of the wholly rational life (which no rational person would actually want to live!). |
| 21394 | Philosophy is knowing each logos, how they fit together, and what follows from them [Epictetus] |
| Full Idea: [Philosophical speculation] consists in knowing the elements of 'logos', what each of them is like, how they fit together, and what follows from them. | |
| From: Epictetus (The Discourses [c.56], 4.08.14), quoted by A.A. Long - Hellenistic Philosophy 4.1 | |
| A reaction: [Said to echo Zeno] If you substitute understanding for 'logos' (plausibly), I think this is exactly the view of philosophy I would subscribe to. We want to understand each aspect of life, and we want those understandings to cohere with one another. |
| 20876 | Philosophy investigates the causes of disagreements, and seeks a standard for settling them [Epictetus] |
| Full Idea: The start of philosophy is perception of the mutual conflict among people, and a search for its cause, plus the rejection and distrust of mere opinion, an investigation to see if opinion is right, and the discovery of some canon, like scales for weighing. | |
| From: Epictetus (The Discourses [c.56], 2.11.13) | |
| A reaction: So the number one aim of philosophy is epistemological, to find the criterion for true opinion. But it starts in real life, and would cease to trade if people would just agree. I think we should set the bar higher than that. |
| 3807 | Reason is and ought to be the slave of the passions [Hume] |
| Full Idea: Reason is and ought to be the slave of the passions, and can never pretend to any other office than to serve and obey them. | |
| From: David Hume (Treatise of Human Nature [1739], II.III.3) |
| 23344 | Reason itself must be compounded from some of our impressions [Epictetus] |
| Full Idea: What is reason itself? Something compounded from impressions of a certain kind. | |
| From: Epictetus (The Discourses [c.56], 1.20.05) | |
| A reaction: This seems to be the only escape from the dead end attempts to rationally justify reason. Making reason a primitive absolute is crazy metaphysics. |
| 23343 | Because reason performs all analysis, we should analyse reason - but how? [Epictetus] |
| Full Idea: Since it is reason that analyses and completes all other things, reason itself should not be left unanalysed. But by what shall it be analysed? ..That is why philosophers put logic first, just as when measuring grain we first examine the measure. | |
| From: Epictetus (The Discourses [c.56], 1.17.01) | |
| A reaction: The problem of the definitive metre rule in Paris. I say we have to test reason against the physical world, and the measure of reason is truth. Something has to be primitive, but reason is too vague for that role. Idea 23344 agrees with me! |
| 8649 | Two numbers are equal if all of their units correspond to one another [Hume] |
| Full Idea: When two numbers are so combin'd, as that the one has always a unit answering to every unit of the other, we pronounce them equal. | |
| From: David Hume (Treatise of Human Nature [1739], I.III.1) | |
| A reaction: This became known as Hume's Principle after Frege made use of it for logicism (Foundations §63). It reduces equality to something fairly simple and visual (one-to-one correspondence). But we also say that two logicians or musicians are 'equal' in ability. |
| 21291 | There is no medium state between existence and non-existence [Hume] |
| Full Idea: Betwixt unity and number there can be no medium; no more than betwixt existence and non-existence. | |
| From: David Hume (Treatise of Human Nature [1739], I.IV.2) | |
| A reaction: Just to confirm that, as you would expect, the great empiricist has no time for 'subsistence', or shadows and holes having lower grade existece. |
| 11942 | Power is the possibility of action, as discovered by experience [Hume] |
| Full Idea: Power consists in the possibility or probability of any action, as discovered by experience and the practice of the world. | |
| From: David Hume (Treatise of Human Nature [1739], p.313), quoted by George Molnar - Powers 5 | |
| A reaction: [page in OUP edn] This strikes me as blatantly false, and typical of those who confuse epistemology with ontology. It implies that a power that takes everyone by surprise is impossible, by definition. |
| 11949 | There may well be powers in things, with which we are quite unacquainted [Hume] |
| Full Idea: I am, indeed, ready to allow, that there may be several qualities both in material and immaterial objects, with which we are utterly unacquainted; and if we please to call these powers and efficiency, 'twill be be of little consequence to the world. | |
| From: David Hume (Treatise of Human Nature [1739], p.168), quoted by George Molnar - Powers 7.2.1 | |
| A reaction: A delightful air of casual indifference. What the classic empiricists needed was a notion of 'best explanation', which would allow them to leap beyond immediate experience. They made plenty of other leaps beyond experience, though Hume hated them. |
| 11950 | We have no idea of powers, because we have no impressions of them [Hume] |
| Full Idea: We never have any impression that contains any power or efficacy. We never therefore have any idea of power. | |
| From: David Hume (Treatise of Human Nature [1739], p.161), quoted by George Molnar - Powers 7.2.1 | |
| A reaction: [page in Selby-Bigges edn] It seems to me plausible that Hume is utterly wrong, because our own mental lives are a direct and constant experience of the physical powers and efficacies of material objects. |
| 11941 | The distinction between a power and its exercise is entirely frivolous [Hume] |
| Full Idea: The distinction which we sometimes make betwixt a power and the exercise of it is entirely frivolous, and ... neither man nor any other being ought ever to be thought possesst of any ability, unless it be exerted and put into action. | |
| From: David Hume (Treatise of Human Nature [1739], p.311), quoted by George Molnar - Powers 5 | |
| A reaction: [page in OUP] Molnar says this strong intuition is shared by most of us, but I take the world to be full of people who can play the piano or speak Spanish, but never actually do it. [but see Idea 11942] Most wasps never sting anything. |
| 11098 | Momentary impressions are wrongly identified with one another on the basis of resemblance [Hume, by Quine] |
| Full Idea: Momentary impressions, according to Hume, are wrongly identified with one another on the basis of resemblance. | |
| From: report of David Hume (Treatise of Human Nature [1739]) by Willard Quine - Identity, Ostension, and Hypostasis 3 | |
| A reaction: I don't have a Hume quotation for this yet, but Quine is plausibly claiming Hume as a resemblance nominalist, equipped with an error theory about universals. |
| 7954 | If we see a resemblance among objects, we apply the same name to them, despite their differences [Hume] |
| Full Idea: When we have found a resemblance among several objects, that often occur to us, we apply the same name to all of them, whatever differences we may observe in the degrees of their quantity and quality, and whatever other differences may appear among them. | |
| From: David Hume (Treatise of Human Nature [1739], I.I.7) | |
| A reaction: This must to some extent by right, whatever objections can be found. Russell's objection (Idea 4441) wouldn't alter the truth of Hume's observation, thought Hume is attacking universals and Russell defending them. |
| 21293 | Individuation is only seeing that a thing is stable and continuous over time [Hume] |
| Full Idea: The principle of individuation is nothing but the invariableness and uninterruptedness of any object through a supposed variation of time, by which the mind can trace it in the different periods of its existence. | |
| From: David Hume (Treatise of Human Nature [1739], I.IV.2) | |
| A reaction: Not convinced by this. I can individuate something by an almost instantaneous glimpse. I don't increasingly individuate it as time passes. Instant viewing of type and structure may be enough. |
| 12048 | The only meaning we have for substance is a collection of qualities [Hume] |
| Full Idea: We have no idea of substance, distinct from that of a collection of particular qualities, nor have we any other meaning when we either talk or reason concerning it. | |
| From: David Hume (Treatise of Human Nature [1739], I.I.6) | |
| A reaction: This is the standard empiricist view of such things, firmly stated. It is tempting to say that Hume has simply misunderstood the word, since it is precisely intended to mean not the qualities, but what underlies them, and persists. |
| 13424 | Aristotelians propose accidents supported by substance, but they don't understand either of them [Hume] |
| Full Idea: The peripatetic philosophers carry their fictions still further, and both suppose a substance supporting, which they do not understand, and an accident supported, of which they have as imperfect an idea. The whole system is entirely incomprehensible. | |
| From: David Hume (Treatise of Human Nature [1739], I.IV.3) | |
| A reaction: It seems to me that if you put it to Aristotle that he didn't understand 'substantial form', he would concede the point, but nevertheless say that it was ideal at which knowledge aimed. Locke is much more astute than Hume on this. |
| 21300 | A change more obviously destroys an identity if it is quick and observed [Hume] |
| Full Idea: A change in any considerable part of a body destroys its identity; but 'tis remarkable that where the change is produced gradually and insensibly we are less apt to ascribe to it the same effect. | |
| From: David Hume (Treatise of Human Nature [1739], I.IV.6) | |
| A reaction: Broad spotted that landscapes change too, but so slowly that we barely admit any change at all. The type of change also matters. If my car slowly changes to chocolate the speed of change is a minor factor. |
| 21299 | Changing a part can change the whole, not absolutely, but by its proportion of the whole [Hume] |
| Full Idea: Though the change of any considerable part of a mass of matter destroys the identity of the whole, yet we must measure the greatness of the part, not absolutely, but by its proportion to the whole. | |
| From: David Hume (Treatise of Human Nature [1739], I.IV.6) | |
| A reaction: This seems to nicely demonstrate that the wholeness is in the mind of the perceiver, and does not simply depend on objective facts. Compare the proportion needed to change my pile of mud and my pile of gold. |
| 1330 | If a republic can retain identity through many changes, so can an individual [Hume] |
| Full Idea: As the same individual republic may not only change its members, but also its laws and constitutions; in like manner the same person may vary his character and disposition, as well as his impressions and ideas, without losing his identity. | |
| From: David Hume (Treatise of Human Nature [1739], I.IV.6) |
| 1321 | If identity survives change or interruption, then resemblance, contiguity or causation must unite the parts of it [Hume] |
| Full Idea: The objects which are variable or interrupted, and yet are supposed to continue the same, are such only as consist of a succession of parts, connected together by resemblance, contiguity, or causation. | |
| From: David Hume (Treatise of Human Nature [1739], I.IV.6) |
| 21302 | If a ruined church is rebuilt, its relation to its parish makes it the same church [Hume] |
| Full Idea: If a church which was formerly of brick fell to ruin, the parish can build the same church of free-stone, with modern architecture. Neither the form nor materials are the same, but their relation to the parishioners is sufficient to say they are the same. | |
| From: David Hume (Treatise of Human Nature [1739], I.IV.6) | |
| A reaction: The clearly invites the question of whether this is type-identity or token-identity. If the parish decided they wanted two churches they obviously wouldn't be the same (even if they then demolished the first one). |
| 21303 | We accept the identity of a river through change, because it is the river's nature [Hume] |
| Full Idea: Where the objects are in their nature changeable and inconstant, we admit of a more sudden transition. The nature of a river consists in the motion and change of parts. What is expected appears of less moment than what is unusual and extraordinary. | |
| From: David Hume (Treatise of Human Nature [1739], I.IV.6) | |
| A reaction: Aha! Little does Hume realise how Aristotelian he is! Aristotle may have a more objective view of the 'nature' of a thing, but making inferences about identity over time from a thing's essential nature is pure Aristotle. |
| 21301 | The purpose of the ship makes it the same one through all variations [Hume] |
| Full Idea: The common end [of a ship], in which the parts conspire, is the same under all variations, and affords an easy transition of the imagination from one situation of the body to another. | |
| From: David Hume (Treatise of Human Nature [1739], I.IV.6) | |
| A reaction: It is not true that a ship remains the same under ALL variations. Consider gradually changing a yacht into a racing powerboat. You might say the purpose is then changed, but the slight variations in a yacht can slightly change its purpose. |
| 21290 | Multiple objects cannot convey identity, because we see them as different [Hume] |
| Full Idea: A mutiplicity of objects can never convey the idea of identity. The mind always pronounces the one not to be the other. | |
| From: David Hume (Treatise of Human Nature [1739], I.IV.2) | |
| A reaction: However, if we are talking on the phone about two objects we are viewing, such as two buildings, our descriptions might lead us to conclude that our objects are identical. Thus experience might imply identity. |
| 1207 | Both number and unity are incompatible with the relation of identity [Hume] |
| Full Idea: Both number and unity are incompatible with the relation of identity. | |
| From: David Hume (Treatise of Human Nature [1739], I.IV.2) |
| 21289 | 'An object is the same with itself' is meaningless; it expresses unity, not identity [Hume] |
| Full Idea: In that proposition 'an object is the same with itself', if the idea expressed by the word 'object' were no way distinguished from that meant by 'itself', we should really mean nothing. ...One single object conveys the idea of unity, not that of identity. | |
| From: David Hume (Treatise of Human Nature [1739], I.IV.2) | |
| A reaction: As far as I can see it is mathematicians who like self-identity, to justify x=x, which they need. To say 'this vase is identical with itself' is an empty locution. It expresses either unity or stability over time. See Idea 21292. |
| 21292 | Saying an object is the same with itself is only meaningful over a period of time [Hume] |
| Full Idea: We cannot, in any propriety of speech, say that an object is the same with itself, unless we mean that the object existent at one time is the same with itself at another time. | |
| From: David Hume (Treatise of Human Nature [1739], I.IV.2) | |
| A reaction: This seems correct, but the strict language of identity is superfluous when identifying stolen goods. 'This is my watch', not 'this watch is identical with my watch'. |
| 9428 | Nothing we clearly imagine is absolutely impossible [Hume] |
| Full Idea: 'Tis an established maxim in metaphysics, that whatever the mind clearly conceives includes the idea of possible existence, or in other words, that nothing we imagine is absolutely impossible. | |
| From: David Hume (Treatise of Human Nature [1739], I.II.2) | |
| A reaction: It is important to note that this empiricist approach to what is impossible requires that we 'clearly' conceive the possibility - but how do we evaluate whether we are being clear or not? |
| 4766 | Necessity only exists in the mind, and not in objects [Hume] |
| Full Idea: Necessity …is nothing but an internal impression of the mind, or a determination to carry our thoughts from one object to another. | |
| From: David Hume (Treatise of Human Nature [1739], I.III.16) | |
| A reaction: The classic statement of the empiricist position. Personally I don't believe it. Non-mental necessities are likely to be natural, or to be features of 'Platonic' objects. A big issue… |
| 23359 | We can't believe apparent falsehoods, or deny apparent truths [Epictetus] |
| Full Idea: It is impossible to assent to an apparent falsehood, or to deny an apparent truth. | |
| From: Epictetus (The Discourses [c.56], 3.07.15) | |
| A reaction: The way some philosophers write you would think that most beliefs just result from private whims or social fashion. That happens, of course, but most beliefs result from direct contact with reality. |
| 6526 | Hume says objects are not a construction, but an imaginative leap [Hume, by Robinson,H] |
| Full Idea: Hume's idea is that we move from private impressions to the physical world, not by an unconscious analytical construction but by a spontaneous imaginative leap. | |
| From: report of David Hume (Treatise of Human Nature [1739]) by Howard Robinson - Perception IX.6 | |
| A reaction: The idea that objects are 'constructions' seems to have originated with Russell. Hume seems closer to the actual process, which is virtually instantaneous. They both forget that you can follow up the construction or leap with a cool evaluation. |
| 23356 | Self-evidence is most obvious when people who deny a proposition still have to use it [Epictetus] |
| Full Idea: It is about the strongest proof one could offer of a proposition being evident, that even he who contradicts it finds himself having to make use of it. | |
| From: Epictetus (The Discourses [c.56], 2.20.01) | |
| A reaction: Philosophers sometimes make fools of themselves by trying, by the use of elaborate sophistry, to demolish propositions which are self-evidently true. Don't be one of these philosophers! |
| 6489 | Associationism results from having to explain intentionality just with sense-data [Robinson,H on Hume] |
| Full Idea: The limited theories of Berkeley and Hume have to be reductive, because they have to explain intentionality in terms of some kind of relation between sense-data; this predicament gives rise to the associationist accounts of psychology and meaning. | |
| From: comment on David Hume (Treatise of Human Nature [1739]) by Howard Robinson - Perception 1.4 | |
| A reaction: An illuminating explanation. Robinson seems to be implying that we should accept something like Searle's 'intrinsic' intentionality as basic, rather than intentionality built up from smaller components as Hume and Dennett suggest. |
| 6182 | Even Hume didn't include mathematics in his empiricism [Hume, by Kant] |
| Full Idea: Even Hume did not make empiricism so universal as to include mathematics in it. | |
| From: report of David Hume (Treatise of Human Nature [1739]) by Immanuel Kant - Critique of Practical Reason Pref | |
| A reaction: Hume didn't actually exclude mathematics, and the notion of 'relations of ideas' is a pointer. Subsequent empiricist have offered promising accounts. Personally I like the idea that patterns are the key idea. |
| 12417 | Mathematicians only accept their own proofs when everyone confims them [Hume] |
| Full Idea: There is no Mathematician so expert as to place entire confidence in any truth upon his discovery of it. ..Every time he runs over his proofs his confidence encreases, ..and is rais'd to perfection by the applause of the learned world. | |
| From: David Hume (Treatise of Human Nature [1739], IV.1.4) | |
| A reaction: [compressed] Quoted by Kitcher, and a nice example of the social nature of 'warrants', even in mathematics. It was illustrated well in the 1990s by the story of the proof of Fermat's Last Theorem by Andrew Wiles. |
| 5548 | Hume became a total sceptic, because he believed that reason was a deception [Hume, by Kant] |
| Full Idea: David Hume gave way entirely to scepticism, since he believed himself to have discovered in what is generally held to be reason a deception of our faculty of cognition. | |
| From: report of David Hume (Treatise of Human Nature [1739]) by Immanuel Kant - Critique of Pure Reason B128 | |
| A reaction: Unfair to Hume, who was very opposed to global scepticism (see Ideas 2240 and 2241), and voted only for 'mitigated scepticism' (see Idea 2242). On the other hand, there is no greater opposition in philosophy than Kant and Hume on 'pure reason'. |
| 7446 | The idea of inductive evidence, around 1660, made Hume's problem possible [Hume, by Hacking] |
| Full Idea: Hume's sceptical problem of induction could not have arisen much before 1660, for there was no concept of inductive evidence in terms of which to raise it. | |
| From: report of David Hume (Treatise of Human Nature [1739]) by Ian Hacking - The Emergence of Probability Cont 19 | |
| A reaction: Hacking is the expert, but Ideas 1683 and 1886 suggest there was some thinking on the problem in the ancient world. The worry about whether the future would be like the past must occasionally have bothered someone. |
| 21806 | Memory, senses and understanding are all founded on the imagination [Hume] |
| Full Idea: The memory, senses, and understanding are all of them founded on the imagination, or the vivacity of our ideas. | |
| From: David Hume (Treatise of Human Nature [1739], I.IV.7.3), quoted by Stephan Schmid - Faculties in Early Modern Philosophy 5 | |
| A reaction: He seems to have in mind his theory of associations, which are not rational. |
| 3819 | Hume's 'bundle' won't distinguish one mind with ten experiences from ten minds [Searle on Hume] |
| Full Idea: Hume's thought that each perception is separate and distinct cannot be right, because then we can't distinguish between one consciousness with ten experiences and ten different consciousnesses. | |
| From: comment on David Hume (Treatise of Human Nature [1739]) by John Searle - Rationality in Action Ch.3.VI | |
| A reaction: Why can't the only connection between them be that they all occur to the speaker who reports to them? How would I know if one of 'my' mental events actually belonged to a neighbour and had strayed. If it was coherent, I would accept it. |
| 1317 | A person is just a fast-moving bundle of perceptions [Hume] |
| Full Idea: I affirm of the rest of mankind, that they are nothing but a bundle or collection of different perceptions, which succeed each other with an inconceivable rapidity, and are in perpetual flux and movement. | |
| From: David Hume (Treatise of Human Nature [1739], I.IV.6) | |
| A reaction: Note that Hume is not just saying what we can know of ourselves, but is asserting a view of what we actually are. The minimal objection to this is to ask how we know that a perception is a member of one big bundle rather than several small ones. |
| 1331 | The parts of a person are always linked together by causation [Hume] |
| Full Idea: Whatever changes a person endures, his several parts are still connected by the relation of causation. | |
| From: David Hume (Treatise of Human Nature [1739], I.IV.6) | |
| A reaction: However, the opposite ends of the universe are linked together by causation, so that will not suffice for a theory of personal identity. One might try to specify a complex and tight network of causation (like a brain!) instead of just 'connection'. |
| 1388 | Hume gives us an interesting sketchy causal theory of personal identity [Perry on Hume] |
| Full Idea: I believe Hume offers an interesting if sketchy theory of personal identity, a causal theory, disguised as the revolutionary discovery that there is no such thing as personal identity | |
| From: comment on David Hume (Treatise of Human Nature [1739], I.IV.6) by John Perry - Introduction to 'Personal Identity' Intro | |
| A reaction: There is certainly a theory there, even though Hume ceased to believe in it, which is nowadays covered by the idea that personal identity is a 'fiction', an arbitrary idea that reifies the focus and direction of a bundle of mental events. |
| 21297 | A person is simply a bundle of continually fluctuating perceptions [Hume] |
| Full Idea: [People] are nothing but a bundle or collection of different perceptions, which succeed each other with an inconceivable rapidity, and are in a continual flux and movement. | |
| From: David Hume (Treatise of Human Nature [1739], I.IV.6) | |
| A reaction: Nowadays we must say that this misses the huge non-conscious aspect of what a person is. He seems to see all mental events as equal. Isn't the experience of deciding to focus on this sentence more 'central' than awareness of your feet? |
| 1316 | Introspection always discovers perceptions, and never a Self without perceptions [Hume] |
| Full Idea: I never can catch myself at any time without a perception, and never can observe any thing but the perception. | |
| From: David Hume (Treatise of Human Nature [1739], I.IV.6) | |
| A reaction: The first half can hardly be denied, but I think the second half is just false. What you observe is not just a raw neutral sense-datum, floating in nothing, but a sense-datum that is deeply coloured by MY interests, interpretations and values. |
| 1333 | Memory only reveals personal identity, by showing cause and effect [Hume] |
| Full Idea: Memory does not so much produce as discover personal identity, by showing us the relation of cause and effect among our different perceptions. | |
| From: David Hume (Treatise of Human Nature [1739], I.IV.6) | |
| A reaction: This is a rather strained proposal, as the revelation of a network of cause and effect seems to have no implications for personal identity (unless only 'I' could be the cause). |
| 1332 | We use memory to infer personal actions we have since forgotten [Hume] |
| Full Idea: We can extend the chain of causes acquired from memory, and consequently the identity of our persons beyond our memory, and can comprehend times, and circumstances, and actions, which we have entirely forgot. | |
| From: David Hume (Treatise of Human Nature [1739], I.IV.6) | |
| A reaction: If the principle is just that 'I am my consciousness' (including of my past), then why should not my consciousness of other people's pasts by included in my identity. How do I know that images in my consciousness are MY memories? |
| 21305 | Memory not only reveals identity, but creates it, by producing resemblances [Hume] |
| Full Idea: The memory not only discovers the identity [of the mind], but also contributes to its production, by producing the relation of resemblance among the perceptions | |
| From: David Hume (Treatise of Human Nature [1739], I.IV.6) | |
| A reaction: This is Hume battling to explain personal identity by his principles of association. He discount 'contiguity'. He doesn't explain how memory creates resemblances. Is not resemblance of idea to fact required in order to remember? |
| 21307 | Who thinks that because you have forgotten an incident you are no longer that person? [Hume] |
| Full Idea: Who will affirm, because he has entirely forgot the incidents of past days, that the present self is not the same person with the self of that time? And by that means overturn all the most established notions of personal identity? | |
| From: David Hume (Treatise of Human Nature [1739], I.IV.6) | |
| A reaction: This is a swipe at one of Locke's most controversial claims (especially when applied to incidents of criminal behaviour). Hume says memory constitutes this identity, but Locke's view says it merely reveals identity. |
| 21306 | Causation unites our perceptions, by producing, destroying and modifying each other [Hume] |
| Full Idea: As to causation, the true idea of the human mind is to consider it as a system of different perceptions, which are linked together by the relation of cause and effect, and mutually produce, destroy, influence and modify each other. | |
| From: David Hume (Treatise of Human Nature [1739], I.IV.6) | |
| A reaction: He suggests that the associations of memory and causation might be sufficient to produce identity of the mind, and he gives the priority to memory. Eventually the good empiricist despairs because you cannot experience the links. |
| 21294 | A continuous lifelong self must be justified by a single sustained impression, which we don't have [Hume] |
| Full Idea: If any impression gives rise to the idea of self, that impression must continue invariably the same, through the whole course of our lives; since self is supposed to exist after that manner. But there is no impression constant and invariable. | |
| From: David Hume (Treatise of Human Nature [1739], I.IV.6) | |
| A reaction: This is a rather dogmatic application of the requirement that all knowledge must be founded in experience. It fails to recognise that knowledge of the thing having the experiences is a rather special case. We must ask for the best explanation. |
| 21295 | When I introspect I can only observe my perceptions, and never a self which has them [Hume] |
| Full Idea: When I enter most intimately into myself I always stumble on some particular perception or other, of heat or cold, love or hatred, pain or pleasure. I never can catch myself at any time without a perception, and never observe any thing but the perception. | |
| From: David Hume (Treatise of Human Nature [1739], I.IV.6) | |
| A reaction: It isn't like looking for your car in the car park. The prior question should be: assuming you do have a persisting self, what would you expect introspection to reveal about it? |
| 21298 | We pretend our perceptions are continuous, and imagine a self to fill the gaps [Hume] |
| Full Idea: We feign the continued existence of the perceptions of our senses, to remove their interruption; and run into the notion of a soul, and self, and substance, to disguise the variation. | |
| From: David Hume (Treatise of Human Nature [1739], I.IV.6) | |
| A reaction: Modern neuroscience (according to Dennett) endorses this, because the brain continually fills in gaps in experience (as it fills in the blindspot during normal vision). |
| 21304 | Identity in the mind is a fiction, like that fiction that plants and animals stay the same [Hume] |
| Full Idea: The identity we ascribe to the mind is only a fictitious one, and of a like kind with that we ascribe to vegetable and animal bodies. It cannot therefore have a different origin, but must proceed from a like operation of the imagination upon like objects. | |
| From: David Hume (Treatise of Human Nature [1739], I.IV.6) | |
| A reaction: Sustained purpose is Hume's common factor. Is the identity over time ascribed to the body of a single animal nothing more than a fiction? It is a wise ascription, compared to stupid ascriptions to gerrymandered objects. |
| 23329 | We make progress when we improve and naturalise our choices, asserting their freedom [Epictetus] |
| Full Idea: Progress is when any of you turns to his own faculty of choice, working at it and perfecting it, so as to bring it fully into harmony with nature; elevated, free, unrestrained, unhindered, faithful, self-respecting. | |
| From: Epictetus (The Discourses [c.56], 1.04.18) | |
| A reaction: [See also Disc.3.5.7] Rationality is the stoic concept of being in 'harmony with nature'. It appears (from reading Frede) that this may be the FIRST EVER reference to free will. Note the very rhetorical way in which it is presented. |
| 23342 | Freedom is acting by choice, with no constraint possible [Epictetus] |
| Full Idea: He is free for whom all things happen in accordance with his choice, and whom no one can constrain. | |
| From: Epictetus (The Discourses [c.56], 1.12.09) | |
| A reaction: Presumable this means that constraint is absolutely impossible, even by Zeus, and not just contingent possibility, when no one sees me raid the fridge. |
| 23330 | Freedom is making all things happen by choice, without constraint [Epictetus] |
| Full Idea: He is free for whom all things happen in accordance with his choice, and whom no one can constrain. | |
| From: Epictetus (The Discourses [c.56], 1.12.09) | |
| A reaction: The idea of 'free' will seems to have resulted from a wide extension of the idea of constraint, with global determinism lurking in the background. |
| 23332 | Zeus gave me a nature which is free (like himself) from all compulsion [Epictetus] |
| Full Idea: Zeus placed my good nature in my own power, and gave it to me as he has it himself, free from all hindrance, compulsion and restraint. | |
| From: Epictetus (The Discourses [c.56], 3.03.10) | |
| A reaction: Although Frede traces the origin of free will to the centrality of choice in moral life (and hence to the elevation of its importance), this remark shows that there is a religious aspect to it. Zeus is supreme, and obviously has free will. |
| 23331 | Not even Zeus can control what I choose [Epictetus] |
| Full Idea: You can fetter my leg, but not even Zeus himself can get the better of my choice. | |
| From: Epictetus (The Discourses [c.56], 1.01.23) | |
| A reaction: This is the beginnings of the idea of free will. It is based on the accurate observation that the intrinsic privacy of a mind means that no external force can be assured of controlling its actions. Epictetus failed to think of internal forces. |
| 23338 | You can fetter my leg, but not even Zeus can control my power of choice [Epictetus] |
| Full Idea: What are you saying, man? Fetter me? You will fetter my leg; but not even Zeus himself can get the better of my choice. | |
| From: Epictetus (The Discourses [c.56], 1.01.23) | |
| A reaction: This seems to be the beginning of the idea of 'absolute' freedom, which is conjured up to preserve perfect inegrity and complete responsibility. Obviously you can be prevented from doing what you choose, so this is not compatibilism. |
| 20875 | If we could foresee the future, we should collaborate with disease and death [Epictetus] |
| Full Idea: The philosophers are right to say that if the honorable and good person knew what was going to happen, he would even collaborate with disease, death and lameness. | |
| From: Epictetus (The Discourses [c.56], 2.10.05) | |
| A reaction: The 'philosophers' must be the earlier stoics, founders of his school. |
| 23347 | If I know I am fated to be ill, I should want to be ill [Epictetus] |
| Full Idea: If I really knew that it was ordained for me to be ill at this moment, I would aspire to be so. | |
| From: Epictetus (The Discourses [c.56], 2.06.10) | |
| A reaction: The rub, of course, is that it is presumably impossible to know what is fated. Book 2.7 is on divination. I don't see any good in a mortally ill person desiring, for that reason alone, to die. Rage against the dying of the light, I say. |
| 20030 | If one event causes another, the two events must be wholly distinct [Hume, by Wilson/Schpall] |
| Full Idea: Hume's maxim is that if one event cause another, then the two events must be wholly distinct. | |
| From: report of David Hume (Treatise of Human Nature [1739]) by Wilson,G/Schpall,S - Action 3 | |
| A reaction: [Anyone know the original reference?] So we are not allowed to say that one part of an event caused another. The charged caused the victory, so they are two events, but in another context the whole battle is one event. |
| 6692 | For Hume, practical reason has little force, because we can always modify our desires [Hume, by Graham] |
| Full Idea: In Hume's account of action, practical reason is not a very forceful guide to conduct, since we can escape its demands by abandoning or modifying our desires. | |
| From: report of David Hume (Treatise of Human Nature [1739]) by Gordon Graham - Eight Theories of Ethics Ch.6 | |
| A reaction: Presumably a desire can be a good reason, and we can passionately desire to be rational, etc., so this is a rather complex issue. 'Pure reason' is not 'all-or-nothing', and neither is pure desire. |
| 8257 | Reason alone can never be a motive to any action of the will [Hume] |
| Full Idea: Reason alone can never be a motive to any action of the will. | |
| From: David Hume (Treatise of Human Nature [1739], II.III.3) | |
| A reaction: This is Hume's notorious total rejection of Socratic intellectualism, a stilleto in the back of the 'age of reason'. Hume thinks desire is the motivator. He's probably right. Why should truth motivate? See Idea 4421. |
| 23325 | Epictetus developed a notion of will as the source of our responsibility [Epictetus, by Frede,M] |
| Full Idea: The notion of will in Epictetus is clearly developed to pinpoint the source of our responsibility for our actions and to identify precisely what it is that makes them our own doings. | |
| From: report of Epictetus (The Discourses [c.56]) by Michael Frede - A Free Will 3 | |
| A reaction: So the key move is that responsibility needs a 'source', rather than being a generalisation about how our actions arise. The next step is demand an 'ultimate' source, and this leads to the idea that this new will is 'free'. This will can be good or bad. |
| 22374 | You can only hold people responsible for actions which arise out of their character [Hume] |
| Full Idea: Where actions proceed not from some cause in the characters and dispositions of the person who performed them, they infix not themselves upon him, and can neither redound to his honour if good, nor infamy if evil. The action in itself may be blameable. | |
| From: David Hume (Treatise of Human Nature [1739], II.III.2), quoted by Philippa Foot - Free Will as Involving Determinism p.70 | |
| A reaction: I agree with Foot that this is wrong. Uncharacteristic actions still reflect on the person. The last sentence is wrong too. If you ignore the agent of an action, it can't be distinguished from a flash of lightning. |
| 20873 | Tragedies are versified sufferings of people impressed by externals [Epictetus] |
| Full Idea: Tragedies are nothing but the sufferings of people who are impressed by externals, performed in the right sort of meter. | |
| From: Epictetus (The Discourses [c.56], 1.04.26) | |
| A reaction: The externals are things like honour, position and wealth. Wonderfully dismissive! |
| 23364 | Homer wrote to show that the most blessed men can be ruined by poor judgement [Epictetus] |
| Full Idea: Did not Homer write to show us that the noblest, the strongest, the richest, the handsomest of men may nevertheless be the most unfortunate and wretched, if they do not hold the judgements that they ought to hold? | |
| From: Epictetus (The Discourses [c.56], 4.10.36) | |
| A reaction: This seems to be right. He clearly wrote about the greatest and most memorable events of recent times, but not just to record triumphs, because almost every hero (in the Iliad, at least) ends in disaster. |
| 23340 | We consist of animal bodies and god-like reason [Epictetus] |
| Full Idea: We have these two elements mingled within us, a body in common with the animals, and reason and intelligence in common with the gods. | |
| From: Epictetus (The Discourses [c.56], 1.03.03) | |
| A reaction: This is what I call Human Exceptionalism, but note that it doesn't invoke a Christian soul or spiritual aspect. This separation of reason goes back at least to Plato. High time we stopped thinking this way. Animals behave very sensibly. |
| 23358 | Every species produces exceptional beings, and we must just accept their nature [Epictetus] |
| Full Idea: In every species nature produces some exceptional being, in oxen, in dogs, in bees, in horses. We do not say to them 'Who are you?' It will tell you 'I am like the purple in the robe. Do not expect me to be like the rest, or find fault with my nature'. | |
| From: Epictetus (The Discourses [c.56], 3.01.23) | |
| A reaction: This idea began with Aristotle's 'great soul', and presumably culminates in Nietzsche, who fills in more detail. In the modern world such people are mostly nothing but trouble. |
| 22382 | We cannot discover vice by studying a wilful murder; that only arises from our own feelings [Hume] |
| Full Idea: Examine wilful murder and see if you can find the matter of fact called vice. You only find certain passions, motives, volitions and thoughts. There is no matter of fact in the case. You can never find it till you turn your reflexion into your own breast. | |
| From: David Hume (Treatise of Human Nature [1739], III.I.2), quoted by Philippa Foot - Hume on Moral Judgement p.77 | |
| A reaction: [...In you breast you find 'disapprobation'] The question Foot asks is whether the facts of the case are relevant to the disapprobation. If they are not, as Hume implies, then it would be rational to feel the same disapprobation about drinking coffee. |
| 4008 | Modern science has destroyed the Platonic synthesis of scientific explanation and morality [Hume, by Taylor,C] |
| Full Idea: From our modern perspective, the Platonic synthesis of scientific explanation and moral insight lies irrecoverably shattered by the rise of natural science. | |
| From: report of David Hume (Treatise of Human Nature [1739]) by Charles Taylor - Sources of the Self §3.2 | |
| A reaction: Modern attempts to challenge Hume's separation of fact from value have failed, but a return to the Greek perspective presents a plausible alternative. |
| 8067 | The problem of getting to 'ought' from 'is' would also apply in getting to 'owes' or 'needs' [Anscombe on Hume] |
| Full Idea: Hume's objection to passing from 'is' to 'ought' would equally apply to passing from 'is' to 'owes' or from 'is' to 'needs'. | |
| From: comment on David Hume (Treatise of Human Nature [1739]) by G.E.M. Anscombe - Modern Moral Philosophy p.176 | |
| A reaction: Profound and important. The empirical and emotivist (nay, nihilist) clinging to the total independence of duties from facts crumbles when looking at facts of human nature or of social groups. Creatures ought to feed; societies ought to flourish. |
| 4578 | You can't move from 'is' to 'ought' without giving some explanation or reason for the deduction [Hume] |
| Full Idea: In many writers I find that instead of the usual propositions 'is' and 'is not', I then find no proposition that is not connected with an 'ought' or an 'ought not'. It is necessary that a reason be given for how one can be a deduction from the other. | |
| From: David Hume (Treatise of Human Nature [1739], III.1.1) | |
| A reaction: A huge claim, the basis of the value-free modern scientific world view. Possible escapes are Greek virtue theory, or Kantian principles, or some sort of a priori values (as in Charles Taylor). |
| 23339 | I will die as becomes a person returning what he does not own [Epictetus] |
| Full Idea: When the time comes, then I will die - as becomes a person who gives back what is not his own. | |
| From: Epictetus (The Discourses [c.56], 1.01.32) | |
| A reaction: There is a tension between his demand that he have full control of his choices, and this humility that says his actual life is not his own. The things which can't be controlled, though, are 'indifferents' so life and death are indifferent. |
| 23345 | Don't be frightened of pain or death; only be frightened of fearing them [Epictetus] |
| Full Idea: It is not pain or death that is to be feared, but the fear of pain or death. | |
| From: Epictetus (The Discourses [c.56], 2.01.13) | |
| A reaction: These two cases are quite different, I would say. I'm much more frightened of pain than I am of the fear of pain, and the opposite view seems absurd. About death, though, I think this is right. Mostly I'm with Spinoza: think about life, not death. |
| 23357 | Knowledge of what is good leads to love; only the wise, who distinguish good from evil, can love [Epictetus] |
| Full Idea: Whoever has knowledge of good things would know how to love them; and how could he who cannot distinguish good things from evil still have to power to love? It follows that the wise man alone has the power to love. | |
| From: Epictetus (The Discourses [c.56], 2.22.03) | |
| A reaction: A rather heartwarming remark, but hard to assess for its truth. Evil people are unable to love? Not even love a cat, or their favourite car? We would never call someone wise if they lacked love. |
| 3650 | Total selfishness is not irrational [Hume] |
| Full Idea: It is not contrary to reason to prefer the destruction of the whole world to the scratching of my finger. | |
| From: David Hume (Treatise of Human Nature [1739], II.III.ii) | |
| A reaction: A famous idea, and the embodiment of moral nihilism. I say nothing could ever refute someone who held such a view. No moral theory can force someone to care, if they just don't. |
| 23363 | The evil for everything is what is contrary to its nature [Epictetus] |
| Full Idea: Where is the paradox if we say that what is evil for everything is what is contrary to its nature? | |
| From: Epictetus (The Discourses [c.56], 4.01.125) | |
| A reaction: A very Greek view. For humans, it must rely on the belief that human nature is essentially good. If I am sometimes grumpy and annoying, why is that not part of my nature? |
| 23328 | The essences of good and evil are in dispositions to choose [Epictetus] |
| Full Idea: The essence of the good is a certain disposition of our choice, and essence of evil likewise. | |
| From: Epictetus (The Discourses [c.56], 1.29.01) | |
| A reaction: This is the origin of Kant's famous view, that the only true good is a good will. This is the alternative to good character or good states of affairs as the good. It points towards the modern more legalistic view of morality, as concerning actions. |
| 23362 | All human ills result from failure to apply preconceptions to particular cases [Epictetus] |
| Full Idea: The cause of all human ills is that people are incapable of applying their general preconceptions to particular cases. | |
| From: Epictetus (The Discourses [c.56], 4.01.42) | |
| A reaction: I'm not sure whether 'preconceptions' is meant pejoratively (as unthinking, and opposed to true principles). This sounds like modern particularism (e.g. Jonathan Dancy) to the letter. |
| 23353 | We have a natural sense of honour [Epictetus] |
| Full Idea: What faculty do you mean? - Have we not a natural sense of honour? - We have. | |
| From: Epictetus (The Discourses [c.56], 2.10.22) | |
| A reaction: This seems unlikely, given the lower status that honour now has with us, compared to two hundred years ago. But there may be a natural sense of status, and of humiliation and shame. |
| 23354 | If someone harms themselves in harming me, then I harm myself by returning the harm [Epictetus] |
| Full Idea: Since he has harmed himself by wronging me, shall not I harm myself by harming him? | |
| From: Epictetus (The Discourses [c.56], 2.10.26) | |
| A reaction: I am very keen on this idea. See Hamlet's remarks to Polonius about 'honour and dignity'. The best strategy for achieving moral excellence is to focus on our own characters, rather than how to act, and to respond to others. |
| 23324 | In the Discourses choice [prohairesis] defines our character and behaviour [Epictetus, by Frede,M] |
| Full Idea: In Epictetus's 'Discourses' the notion of choice [prohairesis] plays perhaps the central role. It is our prohairesis which defines us a person, as the sort of person we are; it is our prohairesis which determines how we behave. | |
| From: report of Epictetus (The Discourses [c.56]) by Michael Frede - A Free Will 3 | |
| A reaction: Frede is charting the gradual move in Greek philosophy from action by desire, reason and habit to action by the will (which then turns out to be 'free'). Character started as dispositions and ended as choices. |
| 23361 | Health is only a good when it is used well [Epictetus] |
| Full Idea: Is health a good and sickness an evil? No. Health is good when used well, and bad when used ill. | |
| From: Epictetus (The Discourses [c.56], 3.20.04) | |
| A reaction: Although I like the idea that health is a natural value, which bridges the gap from facts to values (as a successful function), there is no denying that the health of very evil people is not something the rest of us hope for. |
| 23346 | A person is as naturally a part of a city as a foot is part of the body [Epictetus] |
| Full Idea: Just as the foot in detachment is no longer a foot, so you in detachment are not longer a man. For what is a man? A part of a city, first. | |
| From: Epictetus (The Discourses [c.56], 2.05.26) | |
| A reaction: It is, of course, not true that a detached foot ceases to be a foot (and an isolated human is still a human). This an extreme version of the Aristotelian idea that we are essentially social. It is, though, the sort of view favoured by totalitarianism. |
| 23351 | We are citizens of the universe, and principal parts of it [Epictetus] |
| Full Idea: You are a citizen of the universe, and a part of it; and no subservient, but a principal part of it. | |
| From: Epictetus (The Discourses [c.56], 2.10.03) | |
| A reaction: He got this view from Diogenes of Sinope, one of his heroes. What community you are a part of seems to be a choice as much as a fact. Am I British or a European? |
| 20874 | A citizen is committed to ignore private advantage, and seek communal good [Epictetus] |
| Full Idea: The commitment of the citizen is to have no private advantage, not to deliberate about anything as though one were a separate part. | |
| From: Epictetus (The Discourses [c.56], 2.10.04) | |
| A reaction: This is the modern problem of whether democratic voters are choosing for themselves or for the community. I think we should make an active effort at every election to persuade voters to aim for the communal good. Cf Rawls. |
| 23352 | A citizen should only consider what is good for the whole society [Epictetus] |
| Full Idea: The calling of a citizen is to consider nothing in terms of personal advantage, never to deliberate on anything as though detached from the whole, but be like our hand or foot. | |
| From: Epictetus (The Discourses [c.56], 2.10.04) | |
| A reaction: Fat chance of that in an aggressively capitalist society. I've always voted for what I thought was the common good, and was shocked to gradually realise that many people only vote for what promotes their own interests. Heigh ho. |
| 22604 | Punishing a criminal for moral ignorance is the same as punishing someone for being blind [Epictetus] |
| Full Idea: You should ask 'Ought not this man to be put to death, who is deceived in things of the greatest importance, and is blinded in distinguishing good from evil?' …You then see how inhuman it is, and the same as 'Ought not this blind man to be put to death?' | |
| From: Epictetus (The Discourses [c.56], 1.18.6-7) | |
| A reaction: This is the doctrine of Socrates, that evil is ignorance (and weakness of will [akrasia] is impossible). Epictetus wants us to reason with the man, but what should be do if reasoning fails and he persists in his crimes? |
| 23349 | Asses are born to carry human burdens, not as ends in themselves [Epictetus] |
| Full Idea: An ass is surely not born as an end in itself? No, but because we had need of a back that is able to carry burdens. | |
| From: Epictetus (The Discourses [c.56], 2.08.07) | |
| A reaction: This is the absurd human exceptionalism which plagues our thinking. It would be somewhat true of animals which are specifically bred for human work, such as large cart horses. |
| 14301 | We have no good concept of solidity or matter, because accounts of them are all circular [Hume] |
| Full Idea: In order to form an idea of solidity, we must conceive two bodies pressing on each other without penetration. ..The ideas of secondary qualities are excluded, and the idea of motion depends on extension. This leaves us no just idea of solidity or matter. | |
| From: David Hume (Treatise of Human Nature [1739], I.IV.4), quoted by Stephen Mumford - Dispositions 02.3 | |
| A reaction: [compressed] For me these kind of strict empiricist arguments always recede when you accept the notion of an inference to be best explanation. We have some sort of notion of 'matter', but here the physicist seems to take over. |
| 8382 | For Hume a constant conjunction is both necessary and sufficient for causation [Hume, by Crane] |
| Full Idea: Hume held that constant conjunction between As and Bs is both necessary and sufficient for a causal relation. If As and Bs are conjoined that is sufficient for a causal relation; if A and B are causally related, necessarily they are constantly conjoined. | |
| From: report of David Hume (Treatise of Human Nature [1739]) by Tim Crane - Causation 1.2.2 | |
| A reaction: A helpful connection between Hume and the modern debate about conditions for causation (e.g. Mackie). It sounds as if, to spot the necessary condition, you need to independently see that A and B are causally related, which regularity does not allow. |
| 19274 | Hume seems to presuppose necessary connections between mental events [Kripke on Hume] |
| Full Idea: A well-known objection to Hume's analysis of causation is that he presupposes necessary connections between mental events in the theory. | |
| From: comment on David Hume (Treatise of Human Nature [1739]) by Saul A. Kripke - Wittgenstein on Rules and Private Language n 87 | |
| A reaction: Are these the associations that occur within the mind? I'm not clear about the objection, but record it for interest. |
| 23341 | God created humans as spectators and interpreters of God's works [Epictetus] |
| Full Idea: God has introduced man into the world as a spectator of himself and of his works: and not only as a spectator of them, but an interpreter of them as well. | |
| From: Epictetus (The Discourses [c.56], 1.06.19) | |
| A reaction: This idea (which strikes me as bizarre) was picked up directly by the Christians. I can't imagine every Johnson wanting to creating their own Boswell. If you think we are divinely created, you have to propose some motive for it, I suppose. |
| 23348 | Both god and the good bring benefits, so their true nature seems to be the same [Epictetus] |
| Full Idea: God brings benefits; but the good also brings benefit. It would seem, then, that where the true nature of god is, there too is the true nature of good. | |
| From: Epictetus (The Discourses [c.56], 2.08.01) | |
| A reaction: An enthymeme, missing the premise that there can only be one source of benefit (which sounds unlikely). Does god bring anything other than benefits? And does the good? I think this is an idea from later platonism. |
| 23360 | Each of the four elements in you is entirely scattered after death [Epictetus] |
| Full Idea: Whatever was in you of fire, departs into fire; what was of earth, into earth; what of air, into air; what of water, into water. There is no Hades, nor Acheron. | |
| From: Epictetus (The Discourses [c.56], 3.13.15) | |
| A reaction: This sort of remark may explain why so few of the great Stoic texts (such as those of Chrysippus) survived the Christian era. |
| 21296 | If all of my perceptions were removed by death, nothing more is needed for total annihilation [Hume] |
| Full Idea: Were all my perceptions removed by death, and I could I neither think nor feel nor see nor love nor hate, after the dissolution of my body, I should be enitrely annihilated, nor do I conceive what is further requisite to make me a perfect non-entity. | |
| From: David Hume (Treatise of Human Nature [1739], I.IV.6) | |
| A reaction: 'A perfect non-entity'. How about that for an eighteenth century rejection of immortality of the soul? In the context, his point is that the has no enduring self, apart from this range of experiences. |
