| 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. |
| 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'. |
| 3426 | If one theory is reduced to another, we make fewer independent assumptions about the world [Kim] |
| Full Idea: If we reduce one theory to another, we reduce the number of independent assumptions about the world. | |
| From: Jaegwon Kim (Philosophy of Mind [1996], p.215) |
| 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. |
| 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. |
| 23445 | Naïve set theory says any formula defines a set, and coextensive sets are identical [Linnebo] |
| Full Idea: Naïve set theory is based on the principles that any formula defines a set, and that coextensive sets are identical. | |
| From: Øystein Linnebo (Philosophy of Mathematics [2017], 4.2) | |
| A reaction: The second principle is a standard axiom of ZFC. The first principle causes the trouble. |
| 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. |
| 23447 | In classical semantics singular terms refer, and quantifiers range over domains [Linnebo] |
| Full Idea: In classical semantics the function of singular terms is to refer, and that of quantifiers, to range over appropriate domains of entities. | |
| From: Øystein Linnebo (Philosophy of Mathematics [2017], 7.1) |
| 23443 | The axioms of group theory are not assertions, but a definition of a structure [Linnebo] |
| Full Idea: Considered in isolation, the axioms of group theory are not assertions but comprise an implicit definition of some abstract structure, | |
| From: Øystein Linnebo (Philosophy of Mathematics [2017], 3.5) | |
| A reaction: The traditional Euclidean approach is that axioms are plausible assertions with which to start. The present idea sums up the modern approach. In the modern version you can work backwards from a structure to a set of axioms. |
| 23444 | To investigate axiomatic theories, mathematics needs its own foundational axioms [Linnebo] |
| Full Idea: Mathematics investigates the deductive consequences of axiomatic theories, but it also needs its own foundational axioms in order to provide models for its various axiomatic theories. | |
| From: Øystein Linnebo (Philosophy of Mathematics [2017], 4.1) | |
| A reaction: This is a problem which faces the deductivist (if-then) approach. The deductive process needs its own grounds. |
| 23446 | You can't prove consistency using a weaker theory, but you can use a consistent theory [Linnebo] |
| Full Idea: If the 2nd Incompleteness Theorem undermines Hilbert's attempt to use a weak theory to prove the consistency of a strong one, it is still possible to prove the consistency of one theory, assuming the consistency of another theory. | |
| From: Øystein Linnebo (Philosophy of Mathematics [2017], 4.6) | |
| A reaction: Note that this concerns consistency, not completeness. |
| 23448 | Mathematics is the study of all possible patterns, and is thus bound to describe the world [Linnebo] |
| Full Idea: Philosophical structuralism holds that mathematics is the study of abstract structures, or 'patterns'. If mathematics is the study of all possible patterns, then it is inevitable that the world is described by mathematics. | |
| From: Øystein Linnebo (Philosophy of Mathematics [2017], 11.1) | |
| A reaction: [He cites the physicist John Barrow (2010) for this] For me this is a major idea, because the concept of a pattern gives a link between the natural physical world and the abstract world of mathematics. No platonism is needed. |
| 23441 | Logical truth is true in all models, so mathematical objects can't be purely logical [Linnebo] |
| Full Idea: Modern logic requires that logical truths be true in all models, including ones devoid of any mathematical objects. It follows immediately that the existence of mathematical objects can never be a matter of logic alone. | |
| From: Øystein Linnebo (Philosophy of Mathematics [2017], 2) | |
| A reaction: Hm. Could there not be a complete set of models for a theory which all included mathematical objects? (I can't answer that). |
| 23442 | Game Formalism has no semantics, and Term Formalism reduces the semantics [Linnebo] |
| Full Idea: Game Formalism seeks to banish all semantics from mathematics, and Term Formalism seeks to reduce any such notions to purely syntactic ones. | |
| From: Øystein Linnebo (Philosophy of Mathematics [2017], 3.3) | |
| A reaction: This approach was stimulated by the need to justify the existence of the imaginary number i. Just say it is a letter! |
| 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. |
| 3431 | Supervenience suggest dependence without reduction (e.g. beauty) [Kim] |
| Full Idea: Supervenience opens up the possibility of a relationship that gives us determination, or dependence, without reduction (as beauty supervenes on physical properties, but can't be given a physical definition). | |
| From: Jaegwon Kim (Philosophy of Mind [1996], p.223) | |
| A reaction: Beauty is a bad analogy, since it rather obviously involves a beholder. There is nothing more to a statue than a substance of a certain shape. There are no good analogies for this sort of supervenience, because it doesn't exist. |
| 3437 | 'Physical facts determine all the facts' is the physicalists' slogan [Kim] |
| Full Idea: Physicalists are fond of saying that physical facts determine all the facts. | |
| From: Jaegwon Kim (Philosophy of Mind [1996], p.232) | |
| A reaction: I totally agree with this slogan. As a view, it seems to me that it is reinforced by essentialism (see the ideas of Brian Ellis), which gives some indication of how facts are physically determined, and why there is no alternative. |
| 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 |
| 3430 | Resemblance or similarity is the core of our concept of a property [Kim] |
| Full Idea: Resemblance or similarity is the very core of our concept of a property. | |
| From: Jaegwon Kim (Philosophy of Mind [1996], p.219) |
| 3432 | Is weight a 'resultant' property of water, but transparency an 'emergent' property? [Kim] |
| Full Idea: Emergent properties are said to be irreducible to, and unpredictable from, the lower-level phenomena from which they emerge (as weight is a 'resultant' property, but the transparency of water is an 'emergent' property). | |
| From: Jaegwon Kim (Philosophy of Mind [1996], p.228) | |
| A reaction: So weight is predictable, but transparency is a surprise? But presumably the transparency of water is totally predictable, once you understand it. Emergent properties are either dualist or reducible, in my view. |
| 3434 | Emergent properties are 'brute facts' (inexplicable), but still cause things [Kim] |
| Full Idea: For the emergentist why pain emerges when C-fibres are excited remains a mystery (a 'brute fact'), but such properties then take on a life of their own as 'downward causation'. | |
| From: Jaegwon Kim (Philosophy of Mind [1996], p.229) | |
| A reaction: I don't think there are any 'brute facts', except perhaps at the lowest level of physics. Whatever happened to the principle of sufficient reason? Is the mind like God - a causal source which is uncaused? |
| 3436 | Should properties be individuated by their causal powers? [Kim] |
| Full Idea: Arguably, properties must be individuated in terms of their causal powers. | |
| From: Jaegwon Kim (Philosophy of Mind [1996], p.230) |
| 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? |
| 3406 | Counterfactuals are either based on laws, or on nearby possible worlds [Kim, by PG] |
| Full Idea: For counterfactuals there is the 'nomic-derivational' approach (which logically derives them from laws), and the 'possible world' approach (based on truth in worlds close to the actual one). | |
| From: report of Jaegwon Kim (Philosophy of Mind [1996], p.141) by PG - Db (ideas) |
| 3368 | Mind is basically qualities and intentionality, but how do they connect? [Kim] |
| Full Idea: It is generally held that there are two broad categories of mental phenomena - qualitative states and intentional states (but what do they have in common?). | |
| From: Jaegwon Kim (Philosophy of Mind [1996], p. 23) | |
| A reaction: I am happy to accept this orthodox modern analysis. Putting it more simply: minds exist to enable experience and thought. I judge a priori that the two aspects are not separate. Qualia exist to serve thought, and qualia are necessary for thought. |
| 3392 | Mind is only interesting if it has causal powers [Kim] |
| Full Idea: Unless mental properties have causal powers, there would be little point in worrying about them. | |
| From: Jaegwon Kim (Philosophy of Mind [1996], p.118) | |
| A reaction: This doesn't, on its own, actually rule out epiphenomenalism, but it does show why it barely qualifies as a serious theory. One might, in fact, say that we simply can't worry about something which has no causal powers. The powers might not be physical… |
| 3396 | Experiment requires mental causation [Kim] |
| Full Idea: Experimentation presupposes mental-to-physical causation and is impossible without it. | |
| From: Jaegwon Kim (Philosophy of Mind [1996], p.128) | |
| A reaction: So an epiphenomenalist can't do experiments? Kim implies that there is some special mental assessment of the feedback from physical events, but presumably a robot or a zombie could do experiments. Spiders do experiments. |
| 3397 | Beliefs cause other beliefs [Kim] |
| Full Idea: A brief reflection makes it evident that most of our beliefs are generated by other beliefs we hold, and "generation" here could only mean causal generation. | |
| From: Jaegwon Kim (Philosophy of Mind [1996], p.128) | |
| A reaction: This seems right, and yet implies an uncomfortable determinism, as if all our beliefs just happened to us. I don't claim proper free will, but I do say there is an element in belief formation which is just caused by bunches of beliefs. Call it character. |
| 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. |
| 3367 | Both thought and language have intentionality [Kim] |
| Full Idea: Mental states are not the only things which exhibit intentionality - words and sentences can also refer to or represent facts or states of affairs. | |
| From: Jaegwon Kim (Philosophy of Mind [1996], p. 22) | |
| A reaction: This points to Searle's distinction between 'intrinsic' and 'derived' intentionality (see Idea 3465). We must now explain the difference between verbal intentionality and non-verbal intentionality (both as phenomena, and as information). |
| 3365 | Intentionality involves both reference and content [Kim] |
| Full Idea: There is referential intentionality (that some of our thoughts refer, or are 'about' something) and content intentionality (that propositional attitudes have content or meaning, often expressed by full sentences). | |
| From: Jaegwon Kim (Philosophy of Mind [1996], p. 21) | |
| A reaction: So could these be the external and internal components of content? Which might be the causal/historical component, and the descriptive component? Which might be known by (indirect) acquaintance and description? |
| 3360 | Are pains pure qualia, or do they motivate? [Kim] |
| Full Idea: Are pains only sensory events, or do they also have a motivational component (e.g. aversiveness)? | |
| From: Jaegwon Kim (Philosophy of Mind [1996], p. 7) | |
| A reaction: A nice question. Given the occasional genuine masochist, and the way some people love tastes that others hate, it has always seemed to me that aversiveness was not a necessary property of pain. I couldn't train myself to like pain, though… |
| 3366 | Pain has no reference or content [Kim] |
| Full Idea: Some mental phenomena - in particular, sensations like tickles and pains - do not seem to exhibit either reference or content. | |
| From: Jaegwon Kim (Philosophy of Mind [1996], p. 21) | |
| A reaction: This could be challenged. These sensations cannot be had without a bodily location, and they give information about possible contact or damage. |
| 3389 | Inverted qualia and zombies suggest experience isn't just functional [Kim] |
| Full Idea: If inverted qualia, or absent qualia (zombies), are possible in functionally equivalent systems, qualia are not capturable by functional definitions. | |
| From: Jaegwon Kim (Philosophy of Mind [1996], p.114) | |
| A reaction: The point here (I take it) is that we don't have to go the whole hog of saying the qualia are therefore epiphenomenal, although that is implied. How about a fail-safe situation, where qualia do it for me, and something else does the same for zombies? |
| 3391 | Crosswiring would show that pain and its function are separate [Kim, by PG] |
| Full Idea: If you crosswire your 'pain box' and your 'itch box', the functionalist says you are in pain if the inputs and outputs are for pain, even though the feeling is of an itch. | |
| From: report of Jaegwon Kim (Philosophy of Mind [1996], p.115) by PG - Db (ideas) | |
| A reaction: If functionalists would indeed say this, then the objection seems to me almost conclusive. But they might well say that such simple crosswiring won't work. Itching won't produce pain behaviour - it lacks the correct function. |
| 3422 | Externalism about content makes introspection depend on external evidence [Kim] |
| Full Idea: Externalism about content would have the consequence that most of our knowledge of our own intentional states is indirect and must be based on external evidence. | |
| From: Jaegwon Kim (Philosophy of Mind [1996], p.207) | |
| A reaction: I think this is a confusion, endemic in discussions of externalism. If what Shakespeare meant by 'water' is H2O, or Putnam means by 'elm' what experts say, the point is that their meanings are NOT part of their intentional states, which are bookmarks. |
| 3412 | How do we distinguish our anger from embarrassment? [Kim] |
| Full Idea: How do we know that we are angry rather than embarrassed? | |
| From: Jaegwon Kim (Philosophy of Mind [1996], p.159) | |
| A reaction: A very nice question, because the only answer I (or anyone?) can think of is that they are distinguished by their content. Event A is annoying, while event B is embarrassing. Either of those feelings is almost inconceivable without its content. |
| 3363 | We often can't decide what emotion, or even sensation, we are experiencing [Kim] |
| Full Idea: It is not always easy for us to determine what emotion (or even physical sensations) we are experiencing. | |
| From: Jaegwon Kim (Philosophy of Mind [1996], p. 18) | |
| A reaction: Confused sensations are, I would have thought, rare. Emotions, I think, are only confused when they are weak, and then a lot of the confusion is merely verbal. Our body and intuitions understand the feeling well enough, but we lack the vocabulary. |
| 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. |
| 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. |
| 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 |
| 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. |
| 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. |
| 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? |
| 3409 | Mental substance causation makes physics incomplete [Kim] |
| Full Idea: Since Cartesian dualism implies causation from outside of the physical domain, this means there can be no complete physical theory of the physical domain. | |
| From: Jaegwon Kim (Philosophy of Mind [1996], p.147) | |
| A reaction: This, I think, should be taken as a very strong argument against dualism, rather than as bad news for physics. Some exception might make the closure of physics impossible, but the claim that our brain is the exception looks highly suspect. |
| 3399 | If epiphenomenalism were true, we couldn't report consciousness [Kim] |
| Full Idea: If epiphenomenalism were true, it would be a mystery how such things could be known to us. | |
| From: Jaegwon Kim (Philosophy of Mind [1996], p.130) | |
| A reaction: If a brain were asked whether it was conscious, it would presumably say 'yes', but (if epiphenomenalism were true) the cause of that would have to be brain events, and NOT information that it is conscious, which the brain could not have. Big objection. |
| 3390 | Are inverted or absent qualia coherent ideas? [Kim] |
| Full Idea: Some philosophers doubt the coherence of the very idea of inverted or absent qualia. | |
| From: Jaegwon Kim (Philosophy of Mind [1996], p.115) | |
| A reaction: The possibility of inverted qualia with identical brain structures strikes me as nil, but it would be odd to deny that qualia could be changed by brain surgery, given that insects can see ultra-violet, and some people are colourblind. |
| 3414 | What could demonstrate that zombies and inversion are impossible? [Kim] |
| Full Idea: Is there anything about the qualitative characters of mental states which, should we come to know it, would convince us that zombies and qualia inversion are not really possible? | |
| From: Jaegwon Kim (Philosophy of Mind [1996], p.171) | |
| A reaction: The issue is what causes the qualitative states, not their 'characters'. This strikes me as falling into the trap of thinking that 'what it is like to be..' is a crucial issue. I think zombies are impossible, but not because I experience redness. |
| 3359 | Cartesian dualism fails because it can't explain mental causation [Kim] |
| Full Idea: Its inability to explain the possibility of "mental causation" doomed Cartesian dualism. | |
| From: Jaegwon Kim (Philosophy of Mind [1996], p. 4) | |
| A reaction: This is a modern way of stating the interaction problem. Personally I am inclined to think that dualism was doomed by the spread of the scientific materialist view to every other corner of our knowledge except the mind. Plenty of causes baffle us. |
| 3369 | Logical behaviourism translates mental language to behavioural [Kim] |
| Full Idea: Logical behaviourism says any meaningful statement about mental phenomena can be translated without loss of content into a statement solely about behavioural and physical phenomena. | |
| From: Jaegwon Kim (Philosophy of Mind [1996], p. 29) | |
| A reaction: Also called analytical behaviourism. If we are supposed to infer the ontology of mental states from language, this makes me cross. Maybe we only discuss mentality in behavioural terms because we are epistemologically, and hence linguistically, limited. |
| 3428 | Behaviourism reduces mind to behaviour via bridging principles [Kim] |
| Full Idea: Behaviourism can be considered as an attempt to reduce the mental to the physical via definitional bridge principles (every mental expression being given a behavioural definition). | |
| From: Jaegwon Kim (Philosophy of Mind [1996], p.217) | |
| A reaction: Effectively these would (if they had been discoverable) have been the elusive psycho-physical laws (which Davidson says do not exist). The objection to behaviourism is precisely that there is no fixed behaviour attached to a given mental state. |
| 3380 | Are dispositions real, or just a type of explanation? [Kim] |
| Full Idea: Functionalists take a "realist" approach to dispositions whereas the behaviourist embraces an "instrumentalist" line. | |
| From: Jaegwon Kim (Philosophy of Mind [1996], p. 78) | |
| A reaction: A helpful distinction, which immediately shows why functionalism is superior to behaviourism. There must be some explanation of mental dispositions, and the instrumental view is essentially a refusal to think about the real problem. |
| 3371 | Behaviour depends on lots of mental states together [Kim] |
| Full Idea: Mind-to-behaviour connections are always defeasible - by the occurrence of a further mental state. | |
| From: Jaegwon Kim (Philosophy of Mind [1996], p. 35) | |
| A reaction: But then an object's falling under gravity is always defeasible, by someone catching it first. This popular idea is meant to show that there could, as Davidson puts it, 'no psycho-physical laws', but I suspect the laws are just complex, like weather laws. |
| 3372 | Behaviour is determined by society as well as mental states [Kim] |
| Full Idea: The factors that determine exactly what you are doing when you produce a physical gesture include the customs, habits and conventions that are in force, so it is unlikely that anyone could produce correct behavioural definitions of mental terms. | |
| From: Jaegwon Kim (Philosophy of Mind [1996], p. 36) | |
| A reaction: This problem can be added to the problem that it is hard to specify behaviour without reference to mentalistic terms. The point is clearly right, as what I am doing when I wave my hand in the air will depend on all sorts of conventions and expectations. |
| 3373 | Snakes have different pain behaviour from us [Kim] |
| Full Idea: If it is an analytic truth that anyone in pain has a tendency to wince or groan, what about snakes? | |
| From: Jaegwon Kim (Philosophy of Mind [1996], p. 37) | |
| A reaction: Snakes do, however, exhibit what looks like 'I really don't like that' behaviour, and their rapid avoidance movements are identical to ours. On the other hand, I'm not quite sure what a snake does what it has a stomach upset. I see Kim's point. |
| 3370 | What behaviour goes with mathematical beliefs? [Kim] |
| Full Idea: Is there even a loosely definable range of bodily behaviour that is characteristically exhibited by people when they believe, say, that there is no largest prime number? | |
| From: Jaegwon Kim (Philosophy of Mind [1996], p. 32) | |
| A reaction: This is a highly persuasive argument against behaviourism. Very abstract and theoretical thoughts have no related behaviour, especially among non-mathematicians. I probably believe this idea about numbers, but I can't think what to do about it. |
| 3379 | Neurons seem to be very similar and interchangeable [Kim] |
| Full Idea: Most neurons, it has been said, are pretty much alike and largely interchangeable. | |
| From: Jaegwon Kim (Philosophy of Mind [1996], p. 76) | |
| A reaction: This fact, if true, is highly significant, because the correct theory of the mind must therefore be some sort of functionalism. If what a neuron is is insignificant, then what it does must be what matters. |
| 3388 | Machine functionalism requires a Turing machine, causal-theoretical version doesn't [Kim] |
| Full Idea: Machine functionalism requires a mental state to be a physical realisation of a Turing machine; causal-theoretical functionalism only requires that there be appropriate "internal states". | |
| From: Jaegwon Kim (Philosophy of Mind [1996], p.112) | |
| A reaction: Searle's objection to the Turing machine version seems good - that such a machine has an implicit notion of a user/interpreter, which is absent from this theory of mind. |
| 3384 | The person couldn't run Searle's Chinese Room without understanding Chinese [Kim] |
| Full Idea: It is by no means clear that any human could manage to do what Searle imagines himself to be doing in the Chinese Room - that is, short of throwing away the rule book and learning some real Chinese. | |
| From: Jaegwon Kim (Philosophy of Mind [1996], p.100) | |
| A reaction: It is not clear how a rule book could contain answers to an infinity of possible questions. The Chinese Room is just a very poor analogy with what is envisaged in the project of artificial intelligence. |
| 3393 | How do functional states give rise to mental causation? [Kim] |
| Full Idea: On the functionalist account of mental properties, just where does a mental property get its causal powers? | |
| From: Jaegwon Kim (Philosophy of Mind [1996], p.118) | |
| A reaction: That is the key problem. Something can only have a function if it has intrinsic powers (corkscrews are rigid and helix-shaped). It can't be irrelevant that pain hurts. |
| 3439 | Reductionism gets stuck with qualia [Kim] |
| Full Idea: The main obstacle to mind-body reduction is qualia. | |
| From: Jaegwon Kim (Philosophy of Mind [1996], p.236) | |
| A reaction: Personally I am also impressed by Leibniz's Mill (Idea 2109). No microscope could ever reveal the contents of thought. How can it be so vivid for the owner, but totally undetectable to an observer? |
| 3427 | Reductionism is impossible if there aren't any 'bridge laws' between mental and physical [Kim] |
| Full Idea: Most antireductionist arguments focus on the unavailability of bridge laws to effect the reduction of psychological theory to physical theory (as found in reducing the gas laws to theories about molecules). | |
| From: Jaegwon Kim (Philosophy of Mind [1996], p.216) | |
| A reaction: Reduction can, of course, be achieved by identity rather than by bridge laws. I would say that all that prevents us from predicting mental events from physical ones is the sheer complexity involved. Cf. predicting the detailed results of an explosion. |
| 3376 | We can't assess evidence about mind without acknowledging phenomenal properties [Kim] |
| Full Idea: In order to make sense of the empirical character of mind-brain identity, we must acknowledge the existence of phenomenal properties. | |
| From: Jaegwon Kim (Philosophy of Mind [1996], p. 66) | |
| A reaction: Mind-brain identity is, of course, an ontological theory, not an epistemological one (like empiricism). I suspect that the basis for my belief in reductive physicalism is an intuition, which I am hoping is a rational intuition. Cf. Idea 3989. |
| 3424 | Most modern physicalists are non-reductive property dualists [Kim] |
| Full Idea: The most widely accepted form of physicalism today is the nonreductive variety, ...which combines ontological physicalism with property dualism. | |
| From: Jaegwon Kim (Philosophy of Mind [1996], p.212) | |
| A reaction: I suspect that property dualism is actually in decline, but we will see. I have yet to find a coherent definition of property dualism. If being simultaneously red and square isn't property dualism, then what is it? Sounds like dualism to me. |
| 3413 | Zombies and inversion suggest non-reducible supervenience [Kim] |
| Full Idea: The main argument for the physical supervenience of qualia, then, is the apparent conceivability of zombies and qualia inversion in organisms physically indistinguishable from us. | |
| From: Jaegwon Kim (Philosophy of Mind [1996], p.171) | |
| A reaction: Since neither zombies nor qualia inversion for identical brains seem to me to be even remotely conceivable, I won't trouble myself with the very vague concept of 'supervenience'. |
| 3362 | Supervenience says all souls are identical, being physically indiscernible [Kim] |
| Full Idea: If one accepts the supervenience of mental on physical, this logically implies that there can only be one Cartesian soul, because such souls are physically indiscernible, and hence mentally indiscernible. | |
| From: Jaegwon Kim (Philosophy of Mind [1996], p. 10) | |
| A reaction: Not very persuasive. Brains are certainly discernible, and so are parts of brains. Egos might be mentally discernible. I don't find my notion of personal identity collapsing just because I espouse property dualism. |
| 3374 | Token physicalism isn't reductive; it just says all mental events have some physical properties [Kim] |
| Full Idea: Token physicalism (as opposed to type physicalism) is a weak doctrine which simply says that any event or occurrence with a mental property has some physical property or other. It is not committed to reductionism. | |
| From: Jaegwon Kim (Philosophy of Mind [1996], p. 61) | |
| A reaction: Sounds nice, but it seems incoherent to me. How can something have a physical property if it isn't physical? Try 'it isn't coloured, but has colour properties', or 'not a square, but with square properties'. 'Not divine, but divine properties' maybe. |
| 3433 | The core of the puzzle is the bridge laws between mind and brain [Kim] |
| Full Idea: From the emergentist point of view, the reductionists bridge laws are precisely what need to be explained. Why do these mental-physical correlations hold? | |
| From: Jaegwon Kim (Philosophy of Mind [1996], p.229) | |
| A reaction: Everyone is happy with the bridge laws from chemistry to physics, but no one knows (deep down) why those exact laws hold. We need to understand what consciousness is; its cause will then, I think, become apparent. |
| 3377 | Elimination can either be by translation or by causal explanation [Kim] |
| Full Idea: The two best know attempts to analyse away mental states are Armstrong's causal conception of such states (e.g. pain is a neural event caused by tissue damage), and Smart's 'topic-neutral translation'. | |
| From: Jaegwon Kim (Philosophy of Mind [1996], p. 67) | |
| A reaction: Armstrong's view certainly seems to be missing something, since his 'pain' could do the job without consciousness. I take Smart's approach to be the germ of the right answer. |
| 3438 | Reductionists deny new causal powers at the higher level [Kim] |
| Full Idea: For the reductionist, no new causal powers emerge at higher levels, which goes against the claims of the emergentist and the non-reductive physicalist. | |
| From: Jaegwon Kim (Philosophy of Mind [1996], p.232) | |
| A reaction: I would say that all higher level causes are simply the sums of lower level causes, as in chemistry and physics. What could possibly produced the power at the higher level, apart from the constituents of the thing? Magic? |
| 3440 | Without reductionism, mental causation is baffling [Kim] |
| Full Idea: If reductionism goes, so does the intelligibility of mental causation. | |
| From: Jaegwon Kim (Philosophy of Mind [1996], p.237) | |
| A reaction: Quite so. Substance dualism turns mental causation into a miracle, but property dualism is really no better. If no laws connect brain and mind, you have no account. I don't see how 'reasons are causes' (Davidson) helps at all. |
| 3375 | If an orange image is a brain state, are some parts of the brain orange? [Kim] |
| Full Idea: If an orange visual image is a brain state then, by the indiscernibility of identicals, some brain state must also be orange. | |
| From: Jaegwon Kim (Philosophy of Mind [1996], p. 64) | |
| A reaction: I think this is the Hardest of all Hard Questions: how can I experience orange if my neurons haven't turned orange? What on earth is orangeness? I don't believe it is a 'microproperty' of orange objects; it's in us. |
| 3411 | How do we distinguish our attitudes from one another? [Kim] |
| Full Idea: How do you find out that you believe, rather than, say, doubt or merely hope, that it will rain tomorrow? | |
| From: Jaegwon Kim (Philosophy of Mind [1996], p.159) | |
| A reaction: There should be a special medal created for philosophers who ask reasonable questions which are impossible to answer. They are among the greatest discoveries. |
| 3386 | Folk psychology has been remarkably durable [Kim] |
| Full Idea: Commonsense psychology seems to have an advantage over scientific psychology: its apparent greater stability. Scientific theories seem to come and go. | |
| From: Jaegwon Kim (Philosophy of Mind [1996], p.110) | |
| A reaction: This seems to make the assumption that the folk are in universal long-term agreement about such things, which seems doubtful. See Ideas 2987 and 3410. |
| 3394 | Maybe folk psychology is a simulation, not a theory [Kim] |
| Full Idea: There is the "theory" theory of commonsense psychology, and also a "simulation" theory, which says it is not a matter of laws, but of simulating the behaviour of others, using ourselves as models. | |
| From: Jaegwon Kim (Philosophy of Mind [1996], p.123) | |
| A reaction: Using ourselves as models may be the normal and correct way to relate to people within our own culture, but we have to start theorising when we encounter (e.g.) suicide bombers. |
| 3387 | A culture without our folk psychology would be quite baffling [Kim] |
| Full Idea: A culture that lacked our folk psychology would be unintelligible to us, and its language untranslatable into our own. | |
| From: Jaegwon Kim (Philosophy of Mind [1996], p.110) | |
| A reaction: Surely we can manage to discuss the processing life of a robot, without having to resort to anthropomorphic psychology? Its human-style behaviour will fit, but the rest blatantly won't. |
| 3410 | Folk psychology has adapted to Freudianism [Kim] |
| Full Idea: Freudian depth psychology has now almost achieved the status of folk psychology of the sophisticates. | |
| From: Jaegwon Kim (Philosophy of Mind [1996], p.158) | |
| A reaction: You don't need to be a 'sophisticate' to laugh knowingly when someone makes an embarrassing Freudian slip. Terms like 'neurotic' are commonplace among modern folk. |
| 3382 | A machine with a mind might still fail the Turing Test [Kim] |
| Full Idea: The Turing test is too tough, because something doesn't have to be smart enough to outwit a human (or even have language) to have mentality or intelligence. | |
| From: Jaegwon Kim (Philosophy of Mind [1996], p. 97) | |
| A reaction: Presumably an alien with an IQ of 580 would also fail the Turing test. Indeed people of normal ability, but from a very different culture, might also fail. However, most of us would pass it. |
| 3383 | The Turing Test is too specifically human in its requirements [Kim] |
| Full Idea: The Turing test is too narrow, because it is designed to fool a human interrogator, but there could be creatures which are intelligent but still fail the test. | |
| From: Jaegwon Kim (Philosophy of Mind [1996], p. 97) | |
| A reaction: I think the key test for intelligence would be a capacity for metathought. 'What do you think of the idea that x?' Their thoughts about x might be utterly stupid, of course. How do you measure 'stupid'? |
| 3408 | Two identical brain states could have different contents in different worlds [Kim] |
| Full Idea: States that have the same intrinsic properties - the same neural/physical properties - may have different contents if they are embedded in different environments. | |
| From: Jaegwon Kim (Philosophy of Mind [1996], p.146) | |
| A reaction: This is a way of expressing externalism. It depends what you mean by 'contents'. I struggle to see how "H2O" could be the content of the word 'water' among ancient Greeks. |
| 3420 | Two types of water are irrelevant to accounts of behaviour [Kim] |
| Full Idea: The difference in the two types of 'water' in the Twin Earth experiment seem psychologically irrelevant, for behaviour causation or explanation. | |
| From: Jaegwon Kim (Philosophy of Mind [1996], p.203) | |
| A reaction: A rather important point. No matter how externalist you are about what content really is, people can only act on the internal aspects of it. |
| 3416 | Content may match several things in the environment [Kim] |
| Full Idea: If content is said to be 'covariance' with something in the environment, then the belief that there are horses in the field covaries reliably with the presence of horses in the field, but also the presence of horse genes in the field. | |
| From: Jaegwon Kim (Philosophy of Mind [1996], p.192) | |
| A reaction: That's the end of that interesting proposal, then. Or is it? Looking at the field from a distance this is right, but down the microscope, the covariance varies. The theory lives on. |
| 3418 | 'Arthritis in my thigh' requires a social context for its content to be meaningful [Kim] |
| Full Idea: The example of someone claiming "arthritis in my thigh" shows that the content of belief depends, at least in part but crucially, on the speech practices of the linguistic community in which we situate the subject. | |
| From: Jaegwon Kim (Philosophy of Mind [1996], p.197) | |
| A reaction: Personally I find this social aspect to meaning to be more convincing that Putnam's idea that the physical world is part of meaning. It connects nicely with the social aspects of justification. |
| 3421 | Content is best thought of as truth conditions [Kim] |
| Full Idea: It is standard to take contents as truth conditions. | |
| From: Jaegwon Kim (Philosophy of Mind [1996], p.203) | |
| A reaction: This tradition runs from Frege to Davidson, and has been extended to truth conditions in possible worlds. Rivals will involve intentions, or eliminativism about meaning. |
| 3419 | Pain, our own existence, and negative existentials, are not external [Kim] |
| Full Idea: No external factors seem to be required for Fred's belief that he is in pain, or that he exists, or that there are no unicorns. | |
| From: Jaegwon Kim (Philosophy of Mind [1996], p.198) | |
| A reaction: This is an extremely important observation for anyone who was getting over-excited about external accounts of content. Unicorns might connect externally to horns and horses. |
| 3417 | Content depends on other content as well as the facts [Kim] |
| Full Idea: An objection to the 'covariance' theory of content is that what you believe is influenced, often crucially, by what else you believe. | |
| From: Jaegwon Kim (Philosophy of Mind [1996], p.193) | |
| A reaction: I can't think of a reply to this, if the covariance theory is suggesting that content just IS covariance of mental states with the environment. Externalism says that mind extends into the world. |
| 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. |
| 3403 | We assume people believe the obvious logical consequences of their known beliefs [Kim] |
| Full Idea: We attribute to a subject beliefs that are obvious logical consequences of beliefs already attributed to him. | |
| From: Jaegwon Kim (Philosophy of Mind [1996], p.135) | |
| A reaction: Depends what you mean by 'obvious'. Presumably they must be judged obvious to the believer, but only if they have thought of them. We can't believe all the simple but quirky implications of our beliefs. |
| 3402 | If someone says "I do and don't like x", we don't assume a contradiction [Kim] |
| Full Idea: If someone says "I do and I don't like x", we do not take her to be expressing a literally contradictory belief. | |
| From: Jaegwon Kim (Philosophy of Mind [1996], p.135) | |
| A reaction: It might mean 'one minute I like it, and the next minute I don't', where there seems to be a real contradiction, with a time factor. You can't sustain both preferences with conviction. |
| 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. |
| 3401 | A common view is that causal connections must be instances of a law [Kim] |
| Full Idea: A widely but not universally accepted principle is that causally connected events must instantiate a law. | |
| From: Jaegwon Kim (Philosophy of Mind [1996], p.133) |
| 3407 | Laws are either 'strict', or they involve a 'ceteris paribus' clause [Kim] |
| Full Idea: Some laws are held to be 'strict', and others involve a 'ceteris paribus' clause. | |
| From: Jaegwon Kim (Philosophy of Mind [1996], p.143) |
| 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] |
| Full Idea: Stoics teach that God is unity, and that he is called Mind, and Fate, and Jupiter, and by many names besides. | |
| From: report of Chrysippus (fragments/reports [c.240 BCE]) by Diogenes Laertius - Lives of Eminent Philosophers 07.Ze.68 |
| 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. |
