9199 | Wisdom for one instant is as good as wisdom for eternity [Chrysippus] |
Full Idea: If a person has wisdom for one instant, he is no less happy than he who possesses it for eternity. | |
From: Chrysippus (fragments/reports [c.240 BCE]), quoted by Pierre Hadot - Philosophy as a way of life 8 | |
A reaction: [Hadot quotes Plutarch 'On Common Conceptions' 8,1062a] This makes it sound awfully like some sort of Buddhist 'enlightenment', which strikes like lightning. He does wisdom recognise itself - by a warm glow, or by the cautious thought that got you there? |
20853 | Wise men should try to participate in politics, since they are a good influence [Chrysippus, by Diog. Laertius] |
Full Idea: The wise man will participate in politics unless something prevents him, for he will restrain vice and promote virtue. | |
From: report of Chrysippus (fragments/reports [c.240 BCE]) by Diogenes Laertius - Lives of Eminent Philosophers 07.121 | |
A reaction: [from lost On Ways of Life Bk 1] We have made modern politics so hostile for its participants, thanks to cruel media pressure, that the best people now run a mile from it. Disastrous. |
20772 | Three branches of philosophy: first logic, second ethics, third physics (which ends with theology) [Chrysippus] |
Full Idea: There are three kinds of philosophical theorems, logical, ethical, and physical; of these the logic should be placed first, ethics second, and physics third (and theology is the final topic in physics). | |
From: Chrysippus (fragments/reports [c.240 BCE]), quoted by Plutarch - 70: Stoic Self-contradictions 1035a | |
A reaction: [in his lost 'On Lives' Bk 4] 'Theology is the final topic in physics'! That should create a stir in theology departments. Is this an order of study, or of importance? You come to theology right at the end of your studies. |
2797 | As coherence expands its interrelations become steadily tighter, culminating only in necessary truth [Dancy,J] |
Full Idea: As our system grows in coherence, the interrelations between its parts becomes tighter and tighter;… at the limit contingent truth vanishes, leaving only necessary truth. | |
From: Jonathan Dancy (Intro to Contemporary Epistemology [1985], 14.7) |
5969 | Chrysippus said the uncaused is non-existent [Chrysippus, by Plutarch] |
Full Idea: Chrysippus said that the uncaused is altogether non-existent. | |
From: report of Chrysippus (fragments/reports [c.240 BCE]) by Plutarch - 70: Stoic Self-contradictions 1045c | |
A reaction: The difficulty is to see what empirical basis there can be for such a claim, or what argument of any kind other than an intuition. Induction is the obvious answer, but Hume teaches us scepticism about any claim that 'there can be no exceptions'. |
21388 | The causes of future true events must exist now, so they will happen because of destiny [Chrysippus, by Cicero] |
Full Idea: True future events cannot be such as do not possess causes on account of which they will happen; therefore that which is true must possess causes: and so, when the [true future events] happen they will have happened as a result of destiny. | |
From: report of Chrysippus (fragments/reports [c.240 BCE]) by M. Tullius Cicero - On Fate ('De fato') 9.23-8 | |
A reaction: [exact ref unclear] Presumably the current causes are the truthmakers for the future events, and so the past is the truthmaker of the future, if you are a determinist. |
20780 | Graspable presentations are criteria of facts, and are molded according to their objects [Chrysippus, by Diog. Laertius] |
Full Idea: Of presentations, some are graspable, some non-graspable. The graspable presentation, which they say is the criterion of facts [pragmata], is that which comes from an existing object and is stamped and molded in accordance wth the existing object itself. | |
From: report of Chrysippus (fragments/reports [c.240 BCE]) by Diogenes Laertius - Lives of Eminent Philosophers 07.46 | |
A reaction: [in lost Physics Bk 2] The big modern anguish over truth-as-correspondence is how you are supposed to verify the 'accordance'. This idea seems to blur the ideas of truth and justification (the 'criterion'), and you can't have both as accordance. |
20793 | How could you ever know that the presentation is similar to the object? [Sext.Empiricus on Chrysippus] |
Full Idea: One cannot say that the soul grasps the externally existing objects by means of the states of the senses on the basis of the similarity of these states to the externally existing objects. For on what basis will it know the similarity? | |
From: comment on Chrysippus (fragments/reports [c.240 BCE]) by Sextus Empiricus - Outlines of Pyrrhonism 2.74 | |
A reaction: This exactly the main modern reason for rejecting the correspondence theory of truth. You are welcome to affirm a robust view of truth, but supporting it by claiming a correspondence or resemblance is dubious. |
2768 | The correspondence theory also has the problem that two sets of propositions might fit the facts equally well [Dancy,J] |
Full Idea: The correspondence theory as well as the coherence theory has the problem of more than one set of truths. Why can't two sets of propositions "fit the facts" equally well? | |
From: Jonathan Dancy (Intro to Contemporary Epistemology [1985], 8.2) |
2765 | Rescher says that if coherence requires mutual entailment, this leads to massive logical redundancy [Dancy,J] |
Full Idea: Rescher complains that if coherence requires mutual entailment, then what is entailed is logically redundant, and the whole system is infected with mutual redundancy. | |
From: Jonathan Dancy (Intro to Contemporary Epistemology [1985], 8.1) |
2769 | If one theory is held to be true, all the other theories appear false, because they can't be added to the true one [Dancy,J] |
Full Idea: From the point of view of someone with a theory every other theory is false, because it cannot be added to the true theory. | |
From: Jonathan Dancy (Intro to Contemporary Epistemology [1985], 8.2) |
2766 | Even with a tight account of coherence, there is always the possibility of more than one set of coherent propositions [Dancy,J] |
Full Idea: No matter how tight our account of coherence we have to admit that there may be more than one set of coherent propositions (as Russell pointed out (1907)). | |
From: Jonathan Dancy (Intro to Contemporary Epistemology [1985], 8.2) |
8077 | Stoic propositional logic is like chemistry - how atoms make molecules, not the innards of atoms [Chrysippus, by Devlin] |
Full Idea: In Stoic logic propositions are treated the way atoms are treated in present-day chemistry, where the focus is on the way atoms fit together to form molecules, rather than on the internal structure of the atoms. | |
From: report of Chrysippus (fragments/reports [c.240 BCE]) by Keith Devlin - Goodbye Descartes Ch.2 | |
A reaction: A nice analogy to explain the nature of Propositional Logic, which was invented by the Stoics (N.B. after Aristotle had invented predicate logic). |
20791 | Chrysippus has five obvious 'indemonstrables' of reasoning [Chrysippus, by Diog. Laertius] |
Full Idea: Chrysippus has five indemonstrables that do not need demonstration:1) If 1st the 2nd, but 1st, so 2nd; 2) If 1st the 2nd, but not 2nd, so not 1st; 3) Not 1st and 2nd, the 1st, so not 2nd; 4) 1st or 2nd, the 1st, so not 2nd; 5) 1st or 2nd, not 2nd, so 1st. | |
From: report of Chrysippus (fragments/reports [c.240 BCE]) by Diogenes Laertius - Lives of Eminent Philosophers 07.80-81 | |
A reaction: [from his lost text 'Dialectics'; squashed to fit into one quote] 1) is Modus Ponens, 2) is Modus Tollens. 4) and 5) are Disjunctive Syllogisms. 3) seems a bit complex to be an indemonstrable. |
8078 | Modus ponens is one of five inference rules identified by the Stoics [Chrysippus, by Devlin] |
Full Idea: Modus ponens is just one of the five different inference rules identified by the Stoics. | |
From: report of Chrysippus (fragments/reports [c.240 BCE]) by Keith Devlin - Goodbye Descartes Ch.2 | |
A reaction: Modus ponens strikes me as being more like a definition of implication than a 'rule'. Implication is what gets you from one truth to another. All the implications of a truth must also be true. |
6023 | Every proposition is either true or false [Chrysippus, by Cicero] |
Full Idea: We hold fast to the position, defended by Chrysippus, that every proposition is either true or false. | |
From: report of Chrysippus (fragments/reports [c.240 BCE]) by M. Tullius Cicero - On Fate ('De fato') 38 | |
A reaction: I am intrigued to know exactly how you defend this claim. It may depend what you mean by a proposition. A badly expressed proposition may have indeterminate truth, quite apart from the vague, the undecidable etc. |
5992 | Chrysippus says action is the criterion for existence, which must be physical [Chrysippus, by Tieleman] |
Full Idea: Chrysippus regarded power to act and be acted upon as the criterion for existence or being - a test satisfied by bodies alone. | |
From: report of Chrysippus (fragments/reports [c.240 BCE]) by Teun L. Tieleman - Chrysippus | |
A reaction: This defines existence in terms of causation. Is he ruling out a priori a particle (say) which exists, but never interacts with anything? If so, he is inclining towards anti-realism. |
2781 | Realism says that most perceived objects exist, and have some of their perceived properties [Dancy,J] |
Full Idea: Realism in the theory of perception is that objects we perceive usually do exist, and retain some at least of the properties we perceive them as having. | |
From: Jonathan Dancy (Intro to Contemporary Epistemology [1985], 10.2) |
21673 | There are simple and complex facts; the latter depend on further facts [Chrysippus, by Cicero] |
Full Idea: Chrysippus says there are two classes of facts, simple and complex. An instance of a simple fact is 'Socrates will die at a given date', ...but 'Milo will wrestle at Olympia' is a complex statement, because there can be no wrestling without an opponent. | |
From: report of Chrysippus (fragments/reports [c.240 BCE]) by M. Tullius Cicero - On Fate ('De fato') 13.30 | |
A reaction: We might say that there are atomic and complex facts, but our atomic facts tend to be much simpler, usually just saying some object has some property. |
16652 | Stoics categories are Substrate, Quality, Disposition, and Relation [Chrysippus, by Pasnau] |
Full Idea: The Stoics proposed a rather modest categorisation of Substrate, Quality, Disposition, and Relation. | |
From: report of Chrysippus (fragments/reports [c.240 BCE]) by Robert Pasnau - Metaphysical Themes 1274-1671 12.1 |
17555 | 'One' can mean undivided and not a multitude, or it can add measurement, giving number [Aquinas] |
Full Idea: There are two sorts of one. There is the one which is convertible with being, which adds nothing to being except being undivided; and this deprives of multitude. Then there is the principle of number, which to the notion of being adds measurement. | |
From: Thomas Aquinas (Quaestiones de Potentia Dei [1269], q3 a16 ad 3-um) | |
A reaction: [From a lecture handout] I'm not sure I understand this. We might say, I suppose, that insofar as water is water, it is all one, but you can't count it. Perhaps being 'unified' and being a 'unity' are different? |
16058 | Dion and Theon coexist, but Theon lacks a foot. If Dion loses a foot, he ousts Theon? [Chrysippus, by Philo of Alexandria] |
Full Idea: If two individuals occupied one substance …let one individual (Dion) be thought of as whole-limbed, the other (Theon) as minus one foot. Then let one of Dion's feet be amputated. Theon is the stronger candidate to have perished. | |
From: report of Chrysippus (fragments/reports [c.240 BCE]) by Philo (Alex) - On the Eternity of the World 48 | |
A reaction: [SVF 2.397 - from Chrysippus's lost 'On the Growing Argument'] This is the original of Tibbles the Cat. Dion must persist to change, and then ousts Theon (it seems). Philo protests at Theon ceasing to exist when nothing has happened to him. |
16059 | Change of matter doesn't destroy identity - in Dion and Theon change is a condition of identity [Chrysippus, by Long/Sedley] |
Full Idea: The Growing Argument said any change of matter is a change of identity. Chrysippus presents it with a case (Dion and Theon) where material diminution is the necessary condition of enduring identity, since the diminished footless Dion survives. | |
From: report of Chrysippus (fragments/reports [c.240 BCE]) by AA Long / DN Sedley - Hellenic Philosophers commentary 28:175 | |
A reaction: [The example, in Idea 16058, is the original of Tibbles the Cat] This is a lovely bold idea which I haven't met in the modern discussions - that identity actually requires change. The concept of identity is meaningless without change? |
2745 | A pupil who lacks confidence may clearly know something but not be certain of it [Dancy,J] |
Full Idea: Why isn't certainty required for knowledge? Because we are often prepared to allow that someone does in fact have knowledge when the person is so uncertain they would not claim knowledge for themselves (the 'diffident schoolboy'). | |
From: Jonathan Dancy (Intro to Contemporary Epistemology [1985], 2.1) |
2755 | If senses are fallible, then being open to correction is an epistemological virtue [Dancy,J] |
Full Idea: In my view, once we admit that our beliefs about our sensory states are not infallible, incorrigibility would be a vice rather than a virtue. | |
From: Jonathan Dancy (Intro to Contemporary Epistemology [1985], 4.3) | |
A reaction: This seems to be axiomatic among modern philosophers, and I certainly agree with it. |
5677 | Naïve direct realists hold that objects retain all of their properties when unperceived [Dancy,J] |
Full Idea: The naïve direct realist holds that unperceived objects are able to retain properties of all the types we perceive them as having, which includes not only a shape and a size, but also a colour, a taste and a smell. | |
From: Jonathan Dancy (Intro to Contemporary Epistemology [1985], 10.3) | |
A reaction: This I take to be a completely untenable view, if we are including the qualia of red, sweet or pungent among the properties. It seems uncontroversial that objects retain the capacity to cause redness etc. when they are unperceived. |
5678 | Scientific direct realism says we know some properties of objects directly [Dancy,J] |
Full Idea: The scientific direct realist accepts the directness of our perception of the world, but restricts his realism to a special group of properties, ..not including those which are dependent for their existence upon the existence of a perceiver. | |
From: Jonathan Dancy (Intro to Contemporary Epistemology [1985], 10.3) | |
A reaction: Dancy goes on to say that this distinction is a 'close relative' of Locke's primary/secondary distinction. Am I a direct realist or a representative realist about primary properties? Maybe the distinction dissolves as we unravel the true process. |
5681 | Maybe we are forced from direct into indirect realism by the need to explain perceptual error [Dancy,J] |
Full Idea: Direct realism is unlikely to be able to provide an explanation of perceptual error without collapsing into indirect realism. | |
From: Jonathan Dancy (Intro to Contemporary Epistemology [1985], 10.3) | |
A reaction: If there is an error, there must be two things which don't match: the perception, and the reality. This seems to me a powerful reason for preferring indirect or representative realism. I like the idea that we make mental 'models' (rather than inferences). |
5683 | Indirect realism depends on introspection, the time-lag, illusions, and neuroscience [Dancy,J, by PG] |
Full Idea: The four standard reasons for preferring indirect to direct realism are introspection of our mental processes, the time-lag argument, the argument from illusion, and the findings of neuroscience. | |
From: report of Jonathan Dancy (Intro to Contemporary Epistemology [1985], 10.4) by PG - Db (ideas) | |
A reaction: Ultimately one's views about realism depend on one's views of the mind/brain, and it is the last of the four reasons that sways me. We know enough about the complexity of the brain to accept that it represents reality, with no additional ontology. |
5682 | Internal realism holds that we perceive physical objects via mental objects [Dancy,J] |
Full Idea: Indirect realism holds that in perception we are indirectly aware of the physical objects around us in virtue of a direct awareness of internal, non-physical objects. | |
From: Jonathan Dancy (Intro to Contemporary Epistemology [1985], 10.4) | |
A reaction: This may be a slightly prejudicial definition which invites insoluble questions about the ontological status of the internal 'objects'. It seems to me obvious that we create some sort of inner 'models' or constructions in the process of perception. |
2778 | Phenomenalism includes possible experiences, but idealism only refers to actual experiences [Dancy,J] |
Full Idea: Phenomenalism talks about actual and possible experiences, whereas idealism confines itself to the actual experiences. | |
From: Jonathan Dancy (Intro to Contemporary Epistemology [1985], 9.5) |
5684 | Eliminative idealists say there are no objects; reductive idealists say objects exist as complex experiences [Dancy,J] |
Full Idea: The eliminativist idealist holds that there is no such thing as a material object; there is nothing but experience (idea, sensation). The reductive idealist holds that there are material objects, but they are nothing other than complexes of experience. | |
From: Jonathan Dancy (Intro to Contemporary Epistemology [1985], 10.6) | |
A reaction: Dancy says Berkeley was of the latter type. The distinction doesn't strike me as entirely clear. I can't make much sense of the words 'are' or 'exist' in the second theory. To say it is only experiences translates (to me) as 'doesn't exist'. |
2777 | Extreme solipsism only concerns current experience, but it might include past and future [Dancy,J] |
Full Idea: Extreme solipsism only considers present experiences, but more relaxed solipsism may include past and possible future experiences. | |
From: Jonathan Dancy (Intro to Contemporary Epistemology [1985], 9.5) |
2794 | Knowing that a cow is not a horse seems to be a synthetic a priori truth [Dancy,J] |
Full Idea: The fact that a cow is not a horse is a candidate for a priori synthetic truth. It doesn't seem to be analytic, because you can know what a cow is without knowing what a horse is. | |
From: Jonathan Dancy (Intro to Contemporary Epistemology [1985], 14.3) |
2780 | Perception is either direct realism, indirect realism, or phenomenalism [Dancy,J] |
Full Idea: There are three main families of theories of perception: direct realism, indirect realism, and phenomenalism. | |
From: Jonathan Dancy (Intro to Contemporary Epistemology [1985], 10.2) |
5680 | For direct realists the secondary and primary qualities seem equally direct [Dancy,J] |
Full Idea: For a direct realist our awareness of colour and heat can hardly be of a different order from our awareness of shape and size. Both sorts of properties are presented with equal directness. | |
From: Jonathan Dancy (Intro to Contemporary Epistemology [1985], 10.3) | |
A reaction: This is a good objection to 'direct scientific realism', which claims direct apprehension of primary qualities alongside a totally relative view of secondary qualities. The best response seems to be to move to a representative view of primary properties. |
5679 | We can't grasp the separation of quality types, or what a primary-quality world would be like [Dancy,J] |
Full Idea: There is doubt about whether our experience of the world is such that we can conceive of the sort of separation of primary and secondary qualities which the scientific view calls for, and can understand what the world is like with no secondary qualities. | |
From: Jonathan Dancy (Intro to Contemporary Epistemology [1985], 10.3) | |
A reaction: Dancy attributes these doubts to Berkeley (e.g. Idea 3837). I think what is claimed here is false. Obviously we spend our whole lives immersed in secondary qualities, but separating the different aspects is precisely what scientists (and philosophers) do. |
2782 | We can be looking at distant stars which no longer actually exist [Dancy,J] |
Full Idea: An object such as a distant star can have ceased to exist by the moment at which we are directly aware of it. | |
From: Jonathan Dancy (Intro to Contemporary Epistemology [1985], 10.2) |
2775 | It is not clear from the nature of sense data whether we should accept them as facts [Dancy,J] |
Full Idea: The question whether something which appears as datum should remain as accepted fact is one which is not even partially determined by its origin as datum. | |
From: Jonathan Dancy (Intro to Contemporary Epistemology [1985], 8.5) |
2784 | Appearances don't guarantee reality, unless the appearance is actually caused by the reality [Dancy,J] |
Full Idea: If I stare at a white wall with my brain wired to a virtual reality computer, and it generates a white wall, we wouldn't say I am seeing reality. It seems that the wall itself must in some way cause my perception of it. | |
From: Jonathan Dancy (Intro to Contemporary Epistemology [1985], 11.4) | |
A reaction: But suppose the computer generated in my mind an image of the wall which was actually in front of me? And suppose the computer got its image from the identical wall next door, not from mine? And it was only judged identical because the architect said so |
2785 | Perceptual beliefs may be directly caused, but generalisations can't be [Dancy,J] |
Full Idea: A perceptual belief that p can have as its main cause the fact that p. More general facts (all men are mortal; e=mc2) cannot be the main cause of my belief, even if they do function causally in some way. | |
From: Jonathan Dancy (Intro to Contemporary Epistemology [1985], 11.5) | |
A reaction: Note that the perceptual belief can be the "main" cause; it seems to me that most beliefs are caused by judgements, though I may normally accept beliefs which are directly caused by perception, if I have no reason to challenge them. |
2787 | Memories aren't directly about the past, because time-lags and illusions suggest representation [Dancy,J] |
Full Idea: Direct realism about memory believes the memory is the past. But the time-lag argument and various illusions are powerful here, suggesting indirect realism involving a memory image. | |
From: Jonathan Dancy (Intro to Contemporary Epistemology [1985], 12.2) |
2790 | I can remember plans about the future, and images aren't essential (2+3=5) [Dancy,J] |
Full Idea: Memory is not solely concerned with the past, let alone one's own past (I remember that I must be in London next week), and need not involve images (2+2=4). | |
From: Jonathan Dancy (Intro to Contemporary Epistemology [1985], 12.3) | |
A reaction: I can hardly remember the future, so I presume I am remembering my past commitment to go to London, even if I visualise the future with me in London. The non-necessity of images seems right. I can remember the Mona Lisa without a precise image. |
2791 | Phenomenalism about memory denies the past, or reduces it to present experience [Dancy,J] |
Full Idea: Eliminative phenomenalism about memory holds that there is no such thing as the past, just certain present experiences; reductive phenomenalism holds that there is a past, but it is no more than a complex of those present experiences. | |
From: Jonathan Dancy (Intro to Contemporary Epistemology [1985], 12.4) |
2788 | If perception and memory are indirect, then two things stand between mind and reality [Dancy,J] |
Full Idea: If perception is indirect as well as memory, this means there are two direct objects of awareness between the remembering mind and the original object. | |
From: Jonathan Dancy (Intro to Contemporary Epistemology [1985], 12.2) |
2754 | Foundations are justified by non-beliefs, or circularly, or they need no justification [Dancy,J] |
Full Idea: Foundationalism can get rid of the regress argument with one of three types of belief: those justified by something other than beliefs, those which justify themselves, or those which need no justification. | |
From: Jonathan Dancy (Intro to Contemporary Epistemology [1985], 4.3) | |
A reaction: A nice clear trilemma, and none of them will do, which is why foundationalism is false. I vote for Davidson's view, that only a belief can justify another belief. |
2749 | For internalists we must actually know that the fact caused the belief [Dancy,J] |
Full Idea: The internalist would claim that even if the belief is caused by the true fact to which it refers, it is also necessary that the believer believes that this is how their belief arose, and not some other way. | |
From: Jonathan Dancy (Intro to Contemporary Epistemology [1985], 3.5) | |
A reaction: I'm converted to internalism. If the belief is externally supported in the right way, then it may well be a true belief, but knowledge needs critical faculties, and justifications which can be articulated. |
2770 | Internalists tend to favour coherent justification, but not the coherence theory of truth [Dancy,J] |
Full Idea: Internalists such as Keith Lehrer tend to suggest that we adopt a coherence theory of justification but reject the coherence theory of truth. | |
From: Jonathan Dancy (Intro to Contemporary Epistemology [1985], 8.3) | |
A reaction: I agree with Lehrer. Truth just isn't coherence, for all sorts of well known reasons (found in this database!). High coherence can be totally false. For justification, though, it is the best we have. |
2752 | Foundationalism requires inferential and non-inferential justification [Dancy,J] |
Full Idea: The core of any form of foundationalism is the view that there are two forms of justification - inferential and non-inferential - and that non-inferential justification must be possible to avoid a sceptical regress. | |
From: Jonathan Dancy (Intro to Contemporary Epistemology [1985], 4.1) | |
A reaction: The foundation may be non-inferential, but is it also non-evidential, or devoid of any support at all, apart from its own eloquent self? I can't buy that, I'm afraid. |
2771 | Foundationalists must accept not only the basic beliefs, but also rules of inference for further progress [Dancy,J] |
Full Idea: Foundationalists suppose we need not only basic beliefs, but also principles of inference to move to the more sophisticated superstructure. We may understand what justifies the basic beliefs, but what about the inference principles? | |
From: Jonathan Dancy (Intro to Contemporary Epistemology [1985], 8.3) | |
A reaction: Very nice question. Of course, you can't justify everything, but each part of a system can be scrutinised in turn by the other parts (with scrutinising principles tested pragmatically). |
2756 | If basic beliefs can be false, falsehood in non-basic beliefs might by a symptom [Dancy,J] |
Full Idea: Falsehood in a non-basic belief would be a reason to doubt the basic beliefs which support it, once we have admitted that basic beliefs can be false. | |
From: Jonathan Dancy (Intro to Contemporary Epistemology [1985], 4.3) | |
A reaction: The yearning for foundations arises from the yearning for certainty. If one embraces the fallibilist view of knowledge, as I do, then there is little motivation for foundationalism. |
2753 | Beliefs can only be infallible by having almost no content [Dancy,J] |
Full Idea: Infallible beliefs must have vanishingly small content. No belief with enough content to support the superstructure in which we are really interested is going to be infallible. | |
From: Jonathan Dancy (Intro to Contemporary Epistemology [1985], 4.2) | |
A reaction: I see no reason why a foundationalist should not be a fallibilist, rather than insisting on the infallibility of their basic beliefs. I don't, though, see how basic beliefs can count as knowledge. |
2773 | Coherentism gives a possible justification of induction, and opposes scepticism [Dancy,J] |
Full Idea: Coherentists feel that their approach provides a possible justification for induction, and offers a general stance from which the sceptic can be defused, if not rebutted. | |
From: Jonathan Dancy (Intro to Contemporary Epistemology [1985], 8.3) | |
A reaction: These are two good reasons why I vote for coherentism (about justification, NOT about truth). Coherence is the main tool for leading us to the best explanation. |
2779 | Idealists must be coherentists, but coherentists needn't be idealists [Dancy,J] |
Full Idea: An idealist should perhaps be a coherentist, but there seems to be no reason why the coherentist should be an idealist; the link between the two is all one-way. | |
From: Jonathan Dancy (Intro to Contemporary Epistemology [1985], 9.5) | |
A reaction: I don't see why an idealist shouldn't be a rationalist foundationalist, with a private reality full of certainties founded on simple a priori truths. Personally I'm an empiricist coherentist, this week. |
2786 | For coherentists justification and truth are not radically different things [Dancy,J] |
Full Idea: The coherentist idea is that justification and truth are not properties of radically different types. | |
From: Jonathan Dancy (Intro to Contemporary Epistemology [1985], 11.6) | |
A reaction: Oh. And I thought I was a coherentist. It take it that keeping coherence for foundations separate from coherence as truth is absolutely basic. The latter is nonsense. |
2767 | If it is empirical propositions which have to be coherent, this eliminates coherent fiction [Dancy,J] |
Full Idea: If coherence is grounded in, and is trying to make sense of, a set of empirical propositions, this will eliminate some of the more fanciful sets of coherent propositions, such as the complete Sherlock Holmes stories. | |
From: Jonathan Dancy (Intro to Contemporary Epistemology [1985], 8.2) | |
A reaction: Interestingly, I suspect that embracing the coherence view of justification drives one back to empiricisim (pace Bonjour), because that is the most authoritative part of the pattern of beliefs. |
2776 | Externalism could even make belief unnecessary (e.g. in animals) [Dancy,J] |
Full Idea: One reading of the externalist approach may lead to a rejection of the belief condition for knowledge (in animals, perhaps). | |
From: Jonathan Dancy (Intro to Contemporary Epistemology [1985], 9.3) | |
A reaction: At this point the concept of 'knowledge' seems to disperse into the mist. This pushes me to a 'setting the bar high' view of knowledge. Otherwise plants will have it, and we don't want that. |
2746 | How can a causal theory of justification show that all men die? [Dancy,J] |
Full Idea: How can a causal analysis of justification show that I know that all men die? | |
From: Jonathan Dancy (Intro to Contemporary Epistemology [1985], 2.3) | |
A reaction: I presume he means that inductive generalisations can't be purely causal. The claim that men are immortal is absurd because it is 'unconnected' to what actually happens. |
2747 | Causal theories don't allow for errors in justification [Dancy,J] |
Full Idea: Causal accounts of justification do not allow for the possibility that a false belief may still be justified. | |
From: Jonathan Dancy (Intro to Contemporary Epistemology [1985], 2.4) | |
A reaction: Good. If you switch to what you only think is the cause of your belief, you have gone internalist and ruined the party. You can't deny that a falsehood can be justified, or justification is vacuous. |
2772 | Coherentism moves us towards a more social, shared view of knowledge [Dancy,J] |
Full Idea: An advantage of coherentism is that it directs attention away from the individual's struggle to achieve knowledge (the classical conception), and points to knowledge as a social phenomenon, shared, and increased by means of sharing. | |
From: Jonathan Dancy (Intro to Contemporary Epistemology [1985], 8.3) | |
A reaction: This is exactly the view which I now embrace. Internal coherence is the basis, but that spills out into the community, and into books, and into the relativity of social acceptance. |
2743 | What is the point of arguing against knowledge, if being right undermines your own argument? [Dancy,J] |
Full Idea: What is the point of arguing that justified belief is impossible, for if you were right there could be no reasons for your conclusion? | |
From: Jonathan Dancy (Intro to Contemporary Epistemology [1985], 1.3) |
2751 | Probabilities can only be assessed relative to some evidence [Dancy,J] |
Full Idea: In Probability Calculus probability is only assessed relative to some evidence. | |
From: Jonathan Dancy (Intro to Contemporary Epistemology [1985], 4.1) |
2757 | The argument from analogy rests on one instance alone [Dancy,J] |
Full Idea: As an inductive argument Mill's argument from analogy (other people have inputs and outputs like mine, so the intermediate explanation must be the same) is weak because it is based on a single instance. | |
From: Jonathan Dancy (Intro to Contemporary Epistemology [1985], 5.3) | |
A reaction: The argument may be 'weak' as a piece of pure logic, but when faced with a strange situation, one's own case seems like crucial evidence, like a single eye-witness to a crime. |
2758 | You can't separate mind and behaviour, as the analogy argument attempts [Dancy,J] |
Full Idea: The analogy argument makes the error (as Wittgenstein showed) of assuming that mind is quite separate from behaviour, and yet I can understand what it is for others to have mental states, which is contradictory. | |
From: Jonathan Dancy (Intro to Contemporary Epistemology [1985], 5.3) | |
A reaction: It has always seemed to me that Wittgenstein is excessively behaviourist, and he always seems to be flirting with eliminative views of mind, so he was never bothered about other minds. Minds aren't separate from behaviour, but they are distinct. |
1875 | Dogs show reason in decisions made by elimination [Chrysippus, by Sext.Empiricus] |
Full Idea: A dog makes use of the fifth complex indemonstrable syllogism when, arriving at a spot where three ways meet, after smelling at two roads by which the quarry did not pass, he rushes off at once by the third without pausing to smell. | |
From: report of Chrysippus (fragments/reports [c.240 BCE]) by Sextus Empiricus - Outlines of Pyrrhonism I.69 | |
A reaction: As we might say: either A or B or C; not A; not B; therefore C. I wouldn't want to trust this observation without a lot of analysis of slow-motion photography of dogs as crossroads. Even so, it is a nice challenge to Descartes' view of animals. |
20834 | Chrysippus allows evil to say it is fated, or even that it is rational and natural [Plutarch on Chrysippus] |
Full Idea: Chrysippus gives vice blatant freedom to say not only that it is necessary and according to fate, but even that it occurs according to god's reason and the best nature. | |
From: comment on Chrysippus (fragments/reports [c.240 BCE]) by Plutarch - 70: Stoic Self-contradictions 1050c | |
A reaction: This is Plutarch's criticism of stoic determinism or fatalism. Zeno replied that the punishment for vice may also be fated. It seems that Chysippus did believe that punishments were too harsh, given that vices are fated [p.109]. |
20833 | A swerve in the atoms would be unnatural, like scales settling differently for no reason [Chrysippus, by Plutarch] |
Full Idea: Chrysippus argues against the 'swerve' of the Epicureans, on the grounds that they are doing violence to nature by positing something which is uncaused, and cites dice or scales, which can't settle differently without some cause or difference. | |
From: report of Chrysippus (fragments/reports [c.240 BCE]) by Plutarch - 70: Stoic Self-contradictions 1045c | |
A reaction: That is, the principle of sufficient reason (or of everything having a cause) is derived from observation, not a priori understanding. Pace Leibniz. As in modern discussion, free will or the swerve only occur in our minds, and not elsewhere. |
20808 | Everything is fated, either by continuous causes or by a supreme rational principle [Chrysippus, by Diog. Laertius] |
Full Idea: Chrysippus says (in his 'On Fate') that everything happens by fate. Fate is a continuous string of causes of things which exist or a rational principle according to which the cosmos is managed. | |
From: report of Chrysippus (fragments/reports [c.240 BCE]) by Diogenes Laertius - Lives of Eminent Philosophers 07.148 |
20835 | Chrysippus is wrong to believe in non-occurring future possibilities if he is a fatalist [Plutarch on Chrysippus] |
Full Idea: Chrysippus's accounts of possibility and fate are in conflict. If he is right that 'everything that permits of occurring even if it is not going to occur is possible', then many things are possible which are not according to fate. | |
From: comment on Chrysippus (fragments/reports [c.240 BCE]) by Plutarch - 70: Stoic Self-contradictions 1055e | |
A reaction: A palpable hit, I think. Plutarch refers to Chrysippus's rejection of Diodorus Cronus's Master Argument. Fatalism seems to entail that the only future possibilities are the ones that actually occur. |
20836 | The Lazy Argument responds to fate with 'why bother?', but the bothering is also fated [Chrysippus, by Cicero] |
Full Idea: Chrysippus responded to the Lazy Argument (that the outcome of an illness is fated, so there is no point in calling the doctor) by saying 'calling the doctor is fated just as much as recovering', which he calls 'co-fated'. | |
From: report of Chrysippus (fragments/reports [c.240 BCE]) by M. Tullius Cicero - On Fate ('De fato') 28-30 | |
A reaction: From a pragmatic point of view, this idea also nullifies fatalism, since you can plausibly fight against your fate to your last breath. No evidence could ever be offered in support of fatalism, not even the most unlikely events. |
20837 | Fate is an eternal and fixed chain of causal events [Chrysippus] |
Full Idea: Fate is a sempiternal and unchangeable series and chain of things, rolling and unravelling itself through eternal sequences of cause and effect, of which it is composed and compounded. | |
From: Chrysippus (fragments/reports [c.240 BCE]), quoted by Aulus Gellius - Noctes Atticae 7.2.01 | |
A reaction: It seems that Chrysippus (called by Aulus Gellius 'the chief Stoic philosopher') had a rather grandly rhetorical prose style. |
21679 | When we say events are fated by antecedent causes, do we mean principal or auxiliary causes? [Chrysippus] |
Full Idea: Some causes are perfect and principal, others auxiliary and proximate. Hence when we say that everything takes place by fate owing to antecedent causes, what we wish to be understood is not perfect and principal causes but auxiliary and proximate causes. | |
From: Chrysippus (fragments/reports [c.240 BCE]), quoted by M. Tullius Cicero - On Fate ('De fato') 18.41 | |
A reaction: This move is described by Cicero as enabling Chrysippus to 'escape necessity and to retain fate'. |
5971 | Destiny is only a predisposing cause, not a sufficient cause [Chrysippus, by Plutarch] |
Full Idea: Chrysippus considered destiny to be not a cause sufficient of itself but only a predisposing cause. | |
From: report of Chrysippus (fragments/reports [c.240 BCE], fr 997) by Plutarch - 70: Stoic Self-contradictions 1056b | |
A reaction: This appears to be a rejection of determinism, and is the equivalent of Epicurus' introduction of the 'swerve' in atoms. They had suddenly become bothered about the free will problem in about 305 BCE. There must be other non-destiny causes? |
2744 | Verificationism (the 'verification principle') is an earlier form of anti-realism [Dancy,J] |
Full Idea: Verificationism (the 'verification principle') is an earlier form of anti-realism. | |
From: Jonathan Dancy (Intro to Contemporary Epistemology [1985], 1.note) | |
A reaction: If the one true God announced that there is a real world out there, I might take that as a verification of the fact. |
2760 | Logical positivism implies foundationalism, by dividing weak from strong verifications [Dancy,J] |
Full Idea: The foundationalist claim that there are inferential and non-inferential justifications is mirrored by the claim of logical empiricism (the verification principle) that all significant statements are either strongly or weakly verifiable. | |
From: Jonathan Dancy (Intro to Contemporary Epistemology [1985], 6.2) | |
A reaction: I take it to be characteristic of both to divide the support for something into two types, one of which is basic, and the other built up on the basics. The first step is to decide what is basic. |
2761 | If the meanings of sentences depend on other sentences, how did we learn language? [Dancy,J] |
Full Idea: It is clearly possible to learn a language from scratch, because we have all done it, but if holism is true and the meaning of each sentence depends on the meanings of others, how did we do it? | |
From: Jonathan Dancy (Intro to Contemporary Epistemology [1985], 7.2) | |
A reaction: The question of 'how did it ever get started?' actually seems to block almost every explanation of everything that ever happens. How do I begin to move my hand? |
20787 | A proposition is what can be asserted or denied on its own [Chrysippus] |
Full Idea: A proposition is what can be asserted or denied on its own, for example, 'It is day' or 'Dion is walking'. | |
From: Chrysippus (fragments/reports [c.240 BCE]), quoted by Diogenes Laertius - Lives of Eminent Philosophers 07.65 | |
A reaction: Note the phrase 'on its own'. If you say 'it is day and Dion is walking', that can't be denied on its own, because first the two halves must each be evaluated, so presumably that doesn't count as a stoic proposition. |
2763 | There is an indeterminacy in juggling apparent meanings against probable beliefs [Dancy,J] |
Full Idea: Indeterminacy stems from an interplay between belief and meaning, as with a man who tells you he keeps two rhinoceri in the fridge and squeezes the juice of one for a drink each morning. | |
From: Jonathan Dancy (Intro to Contemporary Epistemology [1985], 7.4) | |
A reaction: I don't understand why an 'interplay' is called an 'indeterminacy'. Typical philosophers. Close examination will usually show whether the change is just in belief, or just in meaning, or in both. |
2762 | Charity makes native beliefs largely true, and Humanity makes them similar to ours [Dancy,J] |
Full Idea: One criterion for successful translation is that it show native beliefs to be largely true (Principle of Charity), and another is that it imputes to natives beliefs we can make sense of them having (Principle of Humanity). | |
From: Jonathan Dancy (Intro to Contemporary Epistemology [1985], 7.4) | |
A reaction: The trouble with such guidelines is that they always have to be 'all things being equal'. Sometimes the natives are really idiotic, and sometimes their attitudes seem quite inhuman. |
20850 | Passions are judgements; greed thinks money is honorable, and likewise drinking and lust [Chrysippus, by Diog. Laertius] |
Full Idea: Chrysippus says (in his On Passions) that the passions are judgements; for greed is a supposition that money is honorable, and similarly for drunkennes and wantonness and others. | |
From: report of Chrysippus (fragments/reports [c.240 BCE]) by Diogenes Laertius - Lives of Eminent Philosophers 07.111 | |
A reaction: This is an endorsement of Socrates's intellectualist reading of weakness of will, as against Aristotle's assigning it to overpowering passions. |
20869 | The highest degree of morality performs all that is appropriate, omitting nothing [Chrysippus] |
Full Idea: He who makes moral progress to the highest degree performs all the appropriate actions in all circumstances, and omits none. | |
From: Chrysippus (fragments/reports [c.240 BCE]), quoted by Sophocles - Sophocles' Electra 4.39.22 | |
A reaction: Hence concerns about omission as well as commission in the practice of ethics can be seen in the light of character and virtue. The world is fully of nice people who act well, but don't do so well on omissions. Car drivers, for example. |
3044 | Stoics say that beauty and goodness are equivalent and linked [Chrysippus, by Diog. Laertius] |
Full Idea: Stoics say the beautiful is the only good. Good is an equivalent term to the beautiful; since a thing is good, it is beautiful; and it is beautiful, therefore it is good. | |
From: report of Chrysippus (fragments/reports [c.240 BCE]) by Diogenes Laertius - Lives of Eminent Philosophers 07.1.59 |
20838 | Fate initiates general causes, but individual wills and characters dictate what we do [Chrysippus] |
Full Idea: The order and reason of fate set in motion the general types and starting points of the causes, but each person's own will [or decisions] and the character of his mind govern the impulses of our thoughts and minds and our very actions. | |
From: Chrysippus (fragments/reports [c.240 BCE]), quoted by Aulus Gellius - Noctes Atticae 7.2.11 | |
A reaction: So if you try and fail it was fate, but if you try and succeed it was you? |
20813 | Human purpose is to contemplate and imitate the cosmos [Chrysippus] |
Full Idea: The human being was born for the sake of contemplating and imitating the cosmos. | |
From: Chrysippus (fragments/reports [c.240 BCE]), quoted by M. Tullius Cicero - On the Nature of the Gods ('De natura deorum') 2.37 | |
A reaction: [This seems to be an idea of Chrysippus] Remind me how to imitate the cosmos. Presumably this is living according to nature, but that becomes more obscure when express like this. |
3045 | Stoics say justice is a part of nature, not just an invented principle [Chrysippus, by Diog. Laertius] |
Full Idea: Stoics say that justice exists by nature, and not because of any definition or principle. | |
From: report of Chrysippus (fragments/reports [c.240 BCE]) by Diogenes Laertius - Lives of Eminent Philosophers 07.1.66 | |
A reaction: cf Idea 3024. Stoics thought that nature is intrinsically rational, and therein lies its justice. 'King Lear' enacts this drama about whether nature is just. |
20774 | Only nature is available to guide action and virtue [Chrysippus] |
Full Idea: What am I to take as the principle of appropriate action and raw material for virtue if I give up nature and what is according to nature? | |
From: Chrysippus (fragments/reports [c.240 BCE]), quoted by Plutarch - On Common Conceptions 1069e | |
A reaction: 'Nature' is awfully vague as a guideline, even when we are told nature is rational. I can only make sense of it as 'human nature', which is more Aristotelian than stoic. 'Go with the flow' and 'lay the cards you are dealt' might capture it. |
20864 | Live in agreement, according to experience of natural events [Chrysippus] |
Full Idea: The goal of life is to live in agreement, which is according to experience of the things which happen by nature. | |
From: Chrysippus (fragments/reports [c.240 BCE]), quoted by John Stobaeus - Anthology 2.06a | |
A reaction: Cleanthes added 'with nature' to Zeno's slogan, and Chyrisppus added this variation. At least it gives you some idea of what the consistent rational principle should be. You still have to assess which aspects of nature should influence us. |
5972 | Living happily is nothing but living virtuously [Chrysippus, by Plutarch] |
Full Idea: According to Chrysippus, living happily consists solely in living virtuously. | |
From: report of Chrysippus (fragments/reports [c.240 BCE], fr139) by Plutarch - 72: Against Stoics on common Conceptions 1060d | |
A reaction: This, along with 'live according to nature', is the essential doctrine of stoicism. This is 'eudaimonia', not the modern idea of feeling nice. Is it possible to admire another person for anything other than virtue? (Yes! Looks, brains, strength, wealth). |
1777 | Pleasure is not the good, because there are disgraceful pleasures [Chrysippus, by Diog. Laertius] |
Full Idea: Pleasure is not the good, because there are disgraceful pleasures, and nothing disgraceful is good. | |
From: report of Chrysippus (fragments/reports [c.240 BCE]) by Diogenes Laertius - Lives of Eminent Philosophers 07.Ze.60 | |
A reaction: I certainly approve of the idea that not all pleasure is intrinsically good. Indeed, I think good has probably got nothing to do with pleasure. 'Disgraceful' is hardly objective though. |
5973 | Justice can be preserved if pleasure is a good, but not if it is the goal [Chrysippus, by Plutarch] |
Full Idea: Chrysippus thinks that, while justice could not be preserved if one should set up pleasure as the goal, it could be if one should take pleasure to be not a goal but simply a good. | |
From: report of Chrysippus (fragments/reports [c.240 BCE], fr 23) by Plutarch - 72: Against Stoics on common Conceptions 1070d | |
A reaction: This is an interesting and original contribution to the ancient debate about pleasure. It shows Aristotle's moderate criticism of pleasure (e.g. Idea 84), but attempts to pinpoint where the danger is. Aristotle says it thwarts achievement of the mean. |
20845 | There are shameful pleasures, and nothing shameful is good, so pleasure is not a good [Chrysippus, by Diog. Laertius] |
Full Idea: Chrysippus (in his On Pleasure) denies even of pleasure that it is a good; for there are also shameful pleasures, and nothing shameful is good. | |
From: report of Chrysippus (fragments/reports [c.240 BCE]) by Diogenes Laertius - Lives of Eminent Philosophers 07.103 | |
A reaction: Socrates seems to have started this line of the thought, to argue that pleasure is not The Good. Stoics are more puritanical. Nothing counts as good if it is capable of being bad. Thus good pleasures are not good, which sounds odd. |
5967 | People need nothing except corn and water [Chrysippus, by Plutarch] |
Full Idea: Chrysippus praises ad nauseam the lines "For what need mortals save two things alone,/ Demeter's grain and draughts of water clear". | |
From: report of Chrysippus (fragments/reports [c.240 BCE]) by Plutarch - 70: Stoic Self-contradictions 1043e | |
A reaction: "Oh, reason not the need!" says King Lear. The remark shows the close affinity of stoicism and cynicism, as the famous story of Diogenes is that he threw away his drinking cup when he realised you could drink with your hands. |
5966 | All virtue is good, but not always praised (as in not lusting after someone ugly) [Chrysippus] |
Full Idea: Although deeds done in accordance with virtue are congenial, not all are cited as examples, such as courageously extending one's finger, or continently abstaining from a half-dead old woman, or not immediately agreeing that three is four. | |
From: Chrysippus (fragments/reports [c.240 BCE], fr 211), quoted by Plutarch - 70: Stoic Self-contradictions 1038f | |
A reaction: Presumably the point (so elegantly expressed - what a shame we have lost most of Chrysippus) is that virtue comes in degrees, even though its value is an absolute. The same has been said (by Russell and Bonjour) about self-evidence. |
20855 | Chrysippus says virtue can be lost (though Cleanthes says it is too secure for that) [Chrysippus, by Diog. Laertius] |
Full Idea: Chrysippus says that virtue can be lost, owing to drunkenness and excess of black bile, whereas Cleanthes says it cannot, because it consists in secure intellectual grasps, and it is worth choosing for its own sake. | |
From: report of Chrysippus (fragments/reports [c.240 BCE]) by Diogenes Laertius - Lives of Eminent Philosophers 07.127 | |
A reaction: Succumbing to drunkenness looks like evidence that you were not truly virtuous. Mental illness is something else. On the whole I agree the Cleanthes. |
5970 | Chrysippus says nothing is blameworthy, as everything conforms with the best nature [Chrysippus, by Plutarch] |
Full Idea: Chrysippus has often written on the theme that there is nothing reprehensible or blameworthy in the universe since all things are accomplished in conformity with the best nature. | |
From: report of Chrysippus (fragments/reports [c.240 BCE]) by Plutarch - 70: Stoic Self-contradictions 1051b | |
A reaction: This is Leibniz's "best of all possible worlds", but deriving the idea from the rightness of nature rather than the perfection of God. Chrysippus has a more plausible ground than Leibniz, as for him nasty things follow from conscious choice. |
20842 | Rational animals begin uncorrupted, but externals and companions are bad influences [Chrysippus, by Diog. Laertius] |
Full Idea: The rational animal is corrupted, sometimes because of the persuasiveness of external activities and sometimes because of the influence of companions. For the starting points provided by nature are uncorrupted. | |
From: report of Chrysippus (fragments/reports [c.240 BCE]) by Diogenes Laertius - Lives of Eminent Philosophers 07.89 | |
A reaction: If companions corrupt us, what corrupted the companions? Aren't we all in this together? And where do the 'external activities' originate? |
20856 | Justice, the law, and right reason are natural and not conventional [Chrysippus, by Diog. Laertius] |
Full Idea: Chrysippus says (in On the Honourable) that justice is natural and not conventional, as are the law and right reason. | |
From: report of Chrysippus (fragments/reports [c.240 BCE]) by Diogenes Laertius - Lives of Eminent Philosophers 07.128 | |
A reaction: How does he explain variations in the law between different states? Presumably some of them have got it wrong. What is the criterion for deciding which laws are natural? |
1779 | We don't have obligations to animals as they aren't like us [Chrysippus, by Diog. Laertius] |
Full Idea: We have no obligations of justice to other animals, because they are dissimilar to us. | |
From: report of Chrysippus (fragments/reports [c.240 BCE]) by Diogenes Laertius - Lives of Eminent Philosophers 07.Ze.66 | |
A reaction: "Dissimilar" begs questions. Some human beings don't seem much like me. How are we going to treat visiting aliens? |
20857 | Justice is irrelevant to animals, because they are too unlike us [Chrysippus, by Diog. Laertius] |
Full Idea: There is no justice between us and other animals because of the dissimilarity between us and them. | |
From: report of Chrysippus (fragments/reports [c.240 BCE]) by Diogenes Laertius - Lives of Eminent Philosophers 07.129 | |
A reaction: [from lost On Justice Bk 1] What would he make of modern revelations about bonobos and chimpanzees? If there is great dissimilarity between some peoples, does that invalidate justice between them? He also said animals exist for our use. |
20812 | Covers are for shields, and sheaths for swords; likewise, all in the cosmos is for some other thing [Chrysippus] |
Full Idea: Just as the cover was made for the sake of the shield, and the sheath for the sword, in the same way everything else except the cosmos was made for the sake of other things. | |
From: Chrysippus (fragments/reports [c.240 BCE]), quoted by M. Tullius Cicero - On the Nature of the Gods ('De natura deorum') 2.37 | |
A reaction: Chrysippus was wise to stop at the cosmos. Similarly, religious teleology had better not ask about the purpose of God. What does he think pebbles are for? Nature is the source of stoic value, so it needs to be purposeful. |
21403 | The later Stoics identified the logos with an air-fire compound, called 'pneuma' [Chrysippus, by Long] |
Full Idea: From Chrysippus onwards, the Stoics identified the logos throughout each world-cycle not with pure fire, but with a compound of fire and air, 'pneuma'. | |
From: report of Chrysippus (fragments/reports [c.240 BCE]) by A.A. Long - Hellenistic Philosophy 4.4.2 | |
A reaction: I suspect this was because breath is so vital to the human body. |
20828 | Fire is a separate element, not formed with others (as was previously believed) [Chrysippus, by Stobaeus] |
Full Idea: In his theory fire is said independently to be an element, since it is not formed together with another one, whereas according to the earlier theory fire is formed with other elements. | |
From: report of Chrysippus (fragments/reports [c.240 BCE]) by John Stobaeus - Anthology 1.10.16c | |
A reaction: The point is that fire precedes the other elements, and is superior to them. |
5975 | Stoics say earth, air, fire and water are the primary elements [Chrysippus, by Plutarch] |
Full Idea: The Stoics call the four bodies - earth and water and air and fire - primary elements. | |
From: report of Chrysippus (fragments/reports [c.240 BCE], fr 444) by Plutarch - 72: Against Stoics on common Conceptions 1085c | |
A reaction: Elsewhere (fr 413) Chrysippus denies that they are all 'primary'. Essentially, though, he seems to be adopting the doctrine of Empedocles and Aristotle, in specific opposition to Epicurus' atomism. |
20819 | The past and the future subsist, but only the present exists [Chrysippus, by Plutarch] |
Full Idea: When he wished to be subtle, Chrysippus wrote that the past part of time and the future part do not exist but subsist, and only the present exists. | |
From: report of Chrysippus (fragments/reports [c.240 BCE]) by Plutarch - On Common Conceptions 1081f | |
A reaction: [from lost On Void] I think I prefer the ontology of Idea 20818. Idea 20819 does not offer an epistemology. Is the present substantial enough to be known? The word 'subsist' is an ontological evasion (even though Russell briefly relied on it). |
20818 | The present does not exist, so our immediate experience is actually part past and part future [Chrysippus, by Plutarch] |
Full Idea: Stoics do not allow a minimal time to exist, and do not want to have a partless 'now'; so what one thinks one has grasped as present is in part future and in part past. | |
From: report of Chrysippus (fragments/reports [c.240 BCE]) by Plutarch - On Common Conceptions 1081c | |
A reaction: [from lost On Parts Bk3-5] I agree with the ontology here, but I take our grasp of the present to be very short-term memory of the past. I ignore special relativity. Chrysippus expressed two views about this; in the other one he was a Presentist. |
20821 | Time is continous and infinitely divisible, so there cannot be a wholly present time [Chrysippus, by Stobaeus] |
Full Idea: Chrysippus says most clearly that no time is wholly present; for since the divisibility of continuous things is infinite, time as a whole is also subject to infinite divisibility by this method of division. | |
From: report of Chrysippus (fragments/reports [c.240 BCE]) by John Stobaeus - Anthology 1.08.42 | |
A reaction: But what is his reason for thinking that time is a continuous thing? There is a minimum time in quantum mechanics (the Planck Time), but do these quantum intervals overlap? Compare Idea 20819. |
3048 | Stoics say that God the creator is the perfection of all animals [Chrysippus, by Diog. Laertius] |
Full Idea: Stoics say that God is an animal immortal, rational, perfect, and intellectual in his happiness, unsusceptible of any kind of evil, having a foreknowledge of the world; however, he is not the figure of a man, and is the creator of the universe. | |
From: report of Chrysippus (fragments/reports [c.240 BCE]) by Diogenes Laertius - Lives of Eminent Philosophers 07.1.72 |
20773 | The origin of justice can only be in Zeus, and in nature [Chrysippus] |
Full Idea: One can find no other starting point or origin for justice except the one derived from Zeus and that derived from the common nature; for everything like this must have that starting point, if we are going to say anything at all about good and bad things. | |
From: Chrysippus (fragments/reports [c.240 BCE]), quoted by Plutarch - 70: Stoic Self-contradictions 1035c | |
A reaction: [in lost 'On Gods' bk 3] This appears to offer two starting points, in the mind of Zeus, and in nature, though since nature is presumed to be rational the two may run together. Is Zeus the embodiment, or the unconscious source, or the maker of decrees? |
5965 | The source of all justice is Zeus and the universal nature [Chrysippus] |
Full Idea: It is not possible to discover any other beginning of justice or any source for it other than that from Zeus and from the universal nature. | |
From: Chrysippus (fragments/reports [c.240 BCE], fr 326), quoted by Plutarch - 70: Stoic Self-contradictions 1035c | |
A reaction: If the source is 'universal nature', that could agree with Plato, but if the source is Zeus, then stoicism is a religion rather than a philosophy. |
3042 | Stoics teach that law is identical with right reason, which is the will of Zeus [Chrysippus, by Diog. Laertius] |
Full Idea: Stoics teach that common law is identical with that right reason which pervades everything, being the same with Zeus, who is the regulator and chief manager of all existing things. | |
From: report of Chrysippus (fragments/reports [c.240 BCE]) by Diogenes Laertius - Lives of Eminent Philosophers 07.1.53 |
1782 | Stoics teach that God is a unity, variously known as Mind, or Fate, or Jupiter [Chrysippus, by Diog. Laertius] |

20830 | Death can't separate soul from body, because incorporeal soul can't unite with body [Chrysippus] |
Full Idea: Death is a separation of soul from body. But nothing incorporeal can be separated from a body. For neither does anything incorporeal touch a body, and the soul touches and is separated from the body. Therefore the soul is not incorporeal. | |
From: Chrysippus (fragments/reports [c.240 BCE]), quoted by Tertullian - The Soul as an 'Astral Body' 5.3 | |
A reaction: This is the classic interaction difficulty for substance dualist theories of mind. |
21404 | There is a rationale in terrible disasters; they are useful to the whole, and make good possible [Chrysippus] |
Full Idea: The evil which occurs in terrible disasters has a rationale [logos] peculiar to itself: for in a sense it occurs in accordance with universal reason, and is not without usefulness in relation to the whole. For without it there could be no good. | |
From: Chrysippus (fragments/reports [c.240 BCE]), quoted by A.A. Long - Hellenistic Philosophy 4.4.5 | |
A reaction: [a quotation from Chrysippus. Plutarch, Comm Not 1065b] A nice question about any terrible disaster is whether it is in some way 'useful', if we take a broader view of things. Almost everything has a good aspect, from that perspective. |
