1. Philosophy / A. Wisdom / 2. Wise People
Wise men participate in politics, especially if it shows moral progress [Stoic school, by Stobaeus]
     Full Idea: The wise man participates in political life, especially in the sort of governments which show some moral progress.
     From: report of Stoic school (fragments/reports [c.200 BCE]) by John Stobaeus - Anthology 2.11b
     A reaction: Nowadays this would probably involve belonging to a political party which offered moral progress.
Wise men are never astonished at things which other people take to be wonders [Stoic school, by Diog. Laertius]
     Full Idea: The wise man is astonished at none of the things which appear to be wonders, such as the caves of Charon or tidal ebbs or hot springs or fiery exhalations from the earth.
     From: report of Stoic school (fragments/reports [c.200 BCE]) by Diogenes Laertius - Lives of Eminent Philosophers 07.123
     A reaction: This seems to me to be correct. Wise people will have thought more extensively about what is possible, and when something they had never imagined occurs, they have the humility to recognise their own limitations.
1. Philosophy / A. Wisdom / 3. Wisdom Deflated
No wise man has yet been discovered [Stoic school, by Cicero]
     Full Idea: According to the Stoics the wise man is hitherto undiscovered.
     From: report of Stoic school (fragments/reports [c.200 BCE]) by M. Tullius Cicero - On the Nature of the Gods ('De natura deorum') 2.133
     A reaction: This could plausibly be axiomatic for the whole of philosophy, since the subject is the 'love of wisdom', and not its acquisition. The subject is the pursuit of wisdom, which would be pointless if we already had it.
1. Philosophy / D. Nature of Philosophy / 4. Divisions of Philosophy
Stoic physics concerns cosmos, elements and causes (with six detailed divisions) [Stoic school, by Diog. Laertius]
     Full Idea: Stoics divide physics into topics on bodies, principles, elements, gods, limits, place and void. The general division is into three topics, concerning the cosmos, the elements and causal explanations.
     From: report of Stoic school (fragments/reports [c.200 BCE]) by Diogenes Laertius - Lives of Eminent Philosophers 07.132
     A reaction: Apart from the gods, not much has changed.
Ethics studies impulse, good, passion, virtue, goals, value, action, appropriateness, encouragement [Stoic school, by Diog. Laertius]
     Full Idea: Stoic divisions of ethics: on impulse, on good and bad things, on passions, on virtue, on the goal, on primary value, on actions, on appropriate actions, and on encouragements and discouragements to action.
     From: report of Stoic school (fragments/reports [c.200 BCE]) by Diogenes Laertius - Lives of Eminent Philosophers 07.84
     A reaction: A substantial part of this is covered by modern Action Theory, rather than by ethics. This describes later stoicism, from Chrysippus onwards. I like the study of 'appropriate actions', which could do with some modern analysis.
1. Philosophy / D. Nature of Philosophy / 5. Aims of Philosophy / a. Philosophy as worldly
True philosophising is not memorising ideas, but living by them [Stoic school, by Stobaeus]
     Full Idea: It is not the man who listens eagerly and memorises what philosophers say who is prepared for philosophising, but the man who is prepared to carry into action what is pronounced in philosophy and to live by it.
     From: report of Stoic school (fragments/reports [c.200 BCE]) by John Stobaeus - Anthology 2.11k
     A reaction: Hence stoicism was seen more as a way of life, and less as theorising. I aim to combine the two. There is a way of life which centres on theorising about life while living it. A life without enquiry is not worth living.
1. Philosophy / F. Analytic Philosophy / 3. Analysis of Preconditions
Some facts are indispensable for an effect, and others actually necessitate the effect [Stoic school, by Cicero]
     Full Idea: The Stoics declare that there is a difference whether a thing is of such a kind that something cannot be effected without it, or such that something must necessarily be effected by it.
     From: report of Stoic school (fragments/reports [c.200 BCE]) by M. Tullius Cicero - On Fate ('De fato') 16.36
     A reaction: This points out that causal preconditions can be either necessary or sufficient for their effect. Because it is a very perceptive point, I surmise that it originated with Chrysippus.
2. Reason / A. Nature of Reason / 2. Logos
The Stoics distinguished spoken logos from logos within the mind [Stoic school, by Plotinus]
     Full Idea: The Stoics distinguished between logos prophorikos ('uttered reasoning') and logos endiathetos ('reason stored within').
     From: report of Stoic school (fragments/reports [c.200 BCE]) by Plotinus - The Enneads 5.1.03 n7
     A reaction: These seems required, since logos is often the 'giving of an account', but it is also the rational principle that rules nature.
Stoics study canons, criteria and definitions, in order to find the truth [Stoic school, by Diog. Laertius]
     Full Idea: They include the study of canons and criteria in order to discover the truth. This is to straighten out the differences among the presentations. And they also include the definitional part for the purposes of recognising the truth.
     From: report of Stoic school (fragments/reports [c.200 BCE]) by Diogenes Laertius - Lives of Eminent Philosophers 07.42
     A reaction: Might we call this categorisation, justifications and definitions? This is part of the study of logos, which comes first in the stoic view of philosophy.
Stoics believed that rational capacity in man (logos) is embodied in the universe [Stoic school, by Long]
     Full Idea: The Stoics believed the faculty in man which enables him to think, to plan and to speak - which they called 'logos' - is literally embodied in the universe at large.
     From: report of Stoic school (fragments/reports [c.200 BCE]) by A.A. Long - Hellenistic Philosophy 4 Intro
     A reaction: This is the stage where logos becomes something dramatically more grand than the logos found in Plato's 'Theaetetus' (but see Heraclitus). It is what is meant by St John's 'In the beginning was the logos' (which is straightforward stoicism).
2. Reason / C. Styles of Reason / 1. Dialectic
Dialectics is mastery of question and answer form [Stoic school, by Diog. Laertius]
     Full Idea: Dialectical knowledge is about conversing correctly in speeches of question and answer form.
     From: report of Stoic school (fragments/reports [c.200 BCE]) by Diogenes Laertius - Lives of Eminent Philosophers 07.42
     A reaction: The whole of ancient Greek philosophy seems to be aimed at speaking well.
2. Reason / D. Definition / 12. Paraphrase
We could refer to tables as 'xs that are arranged tablewise' [Inwagen]
     Full Idea: We could paraphrase 'some chairs are heavier than some tables' as 'there are xs that are arranged chairwise and there are ys that are arranged tablewise and the xs are heavier than the ys'.
     From: Peter van Inwagen (Material Beings [1990], 11)
     A reaction: Liggins notes that this involves plural quantification. Being 'arranged tablewise' has become a rather notorious locution in modern ontology. We still have to retain identity, to pick out the xs.
3. Truth / A. Truth Problems / 3. Value of Truth
Falsehoods corrupt a mind, producing passions and instability [Stoic school, by Diog. Laertius]
     Full Idea: Corruption afflicts the intellect because of falsehoods, and from such a mind there arise many passions and causes of instability.
     From: report of Stoic school (fragments/reports [c.200 BCE]) by Diogenes Laertius - Lives of Eminent Philosophers 07.110
     A reaction: In Dec 2017 this ancient wisdom perfectly fits the current President of the USA.
3. Truth / A. Truth Problems / 5. Truth Bearers
The truth bearers are said to be the signified, or the signifier, or the meaning of the signifier [Stoic school, by Sext.Empiricus]
     Full Idea: Some located the true and the false in the thing signified (Dion himself), some located it in the utterance ('Dion'), and some in the motion of the intellect (what foreigners do not undestand when they hear 'Dion')..
     From: report of Stoic school (fragments/reports [c.200 BCE]) by Sextus Empiricus - Against the Mathematicians 8.11
     A reaction: [View is attributed to Dogmatists, which also includes Epicureans] I love the definition of what we might call 'meaning' as what foreigners fail to understand when they hear it. I don't think the debate has got any further today. His example is one word.
4. Formal Logic / A. Syllogistic Logic / 2. Syllogistic Logic
Stoics like syllogisms, for showing what is demonstrative, which corrects opinions [Stoic school, by Diog. Laertius]
     Full Idea: Stoics say the study of syllogisms is extremely useful; for it indicates what is demonstrative, and this makes a big contribution toward correcting one's opinions; and orderliness and good memory indicate attentive comprehension.
     From: report of Stoic school (fragments/reports [c.200 BCE]) by Diogenes Laertius - Lives of Eminent Philosophers 07.45
     A reaction: The stoics also developed propositional logic. The main point is that they liked formal logic, which is not true of all the ancient schools.
4. Formal Logic / G. Formal Mereology / 1. Mereology
Mereology is 'nihilistic' (just atoms) or 'universal' (no restrictions on what is 'whole') [Inwagen, by Varzi]
     Full Idea: Van Ingwagen writes of 'mereological nihilism' (that only mereological atoms exist) and of 'mereological universalism' (adhering to the principle of Unrestricted Composition).
     From: report of Peter van Inwagen (Material Beings [1990], p.72-) by Achille Varzi - Mereology 4.3
     A reaction: They both look mereologically nihilistic to me, in comparison with an account that builds on 'natural' wholes and their parts. You can only be 'unrestricted' if you view the 'wholes' in your vast ontology as pretty meaningless (as Lewis does, Idea 10660).
5. Theory of Logic / D. Assumptions for Logic / 2. Excluded Middle
The 'Law' of Excluded Middle needs all propositions to be definitely true or definitely false [Inwagen]
     Full Idea: I think the validity of the 'Law' of Excluded Middle depends on the assumption that every proposition is definitely true or definitely false.
     From: Peter van Inwagen (Material Beings [1990], 18)
     A reaction: I think this is confused. He cites vagueness as the problem, but that is a problem for Bivalence. If excluded middle is read as 'true or not-true', that leaves the meaning of 'not-true' open, and never mentions the bivalent 'false'.
Intuitionists deny excluded middle, because it is committed to transcendent truth or objects [Shapiro]
     Full Idea: Intuitionists in mathematics deny excluded middle, because it is symptomatic of faith in the transcendent existence of mathematical objects and/or the truth of mathematical statements.
     From: Stewart Shapiro (Thinking About Mathematics [2000], 1.2)
     A reaction: There are other problems with excluded middle, such as vagueness, but on the whole I, as a card-carrying 'realist', am committed to the law of excluded middle.
5. Theory of Logic / E. Structures of Logic / 1. Logical Form
Stoics avoided universals by paraphrasing 'Man is...' as 'If something is a man, then it is...' [Stoic school, by Long]
     Full Idea: Stoics reduced universals to thoughts or concepts, ...so in order to make universal statements which would not conflict with their metaphysics, they rephrased sentences of the form 'Man is...' as conditionals: 'If something is a man, then it is...'
     From: report of Stoic school (fragments/reports [c.200 BCE]) by A.A. Long - Hellenistic Philosophy 4.3.3
     A reaction: [reference to Sextus, Adv Math 9.8] Predicate logic handles this with ease. It is something like the strategy of Ramsey sentences, for eliminating metaphysical properties.
5. Theory of Logic / E. Structures of Logic / 2. Logical Connectives / c. not
The contradictory of a contradictory is an affirmation [Stoic school, by Diog. Laertius]
     Full Idea: A double contradictory is the contradictory of a contradictory, for example, 'It s not the case that it is not day'. It posits that it is day.
     From: report of Stoic school (fragments/reports [c.200 BCE]) by Diogenes Laertius - Lives of Eminent Philosophers 07.69
     A reaction: Seems like common sense to the stoics, but verifying the double negative may be a different procedure to verifying the affirmative. 'Are you happy?' 'Well ….I'm not unhappy'. 'Is it day yet?' 'Well, it's not night'.
5. Theory of Logic / E. Structures of Logic / 4. Variables in Logic
Variables are just like pronouns; syntactic explanations get muddled over dummy letters [Inwagen]
     Full Idea: Explanations in terms of syntax do not satisfactorily distinguish true variables from dummy or schematic letters. Identifying variables with pronouns, however, provides a genuine explanation of what variables are.
     From: Peter van Inwagen (Material Beings [1990], 02)
     A reaction: I like this because it shows that our ordinary thought and speech use variables all the time ('I've forgotten something - what was it?'). He says syntax is fine for maths, but not for ordinary understanding.
5. Theory of Logic / L. Paradox / 6. Paradoxes in Language / b. The Heap paradox ('Sorites')
There are no heaps [Inwagen]
     Full Idea: Fortunately ....there are no heaps.
     From: Peter van Inwagen (Material Beings [1990], 18)
     A reaction: This is the nihilist view of (inorganic) physical objects. If a wild view solves all sorts of problems, one should take it serious. It is why I take reductive physicalism about the mind seriously. (Well, it's true, actually)
6. Mathematics / A. Nature of Mathematics / 3. Nature of Numbers / b. Types of number
The number 3 is presumably identical as a natural, an integer, a rational, a real, and complex [Shapiro]
     Full Idea: It is surely wise to identify the positions in the natural numbers structure with their counterparts in the integer, rational, real and complex number structures.
     From: Stewart Shapiro (Thinking About Mathematics [2000], 10.2)
     A reaction: The point is that this might be denied, since 3, 3/1, 3.00.., and -3*i^2 are all arrived at by different methods of construction. Natural 3 has a predecessor, but real 3 doesn't. I agree, intuitively, with Shapiro. Russell (1919) disagreed.
6. Mathematics / A. Nature of Mathematics / 3. Nature of Numbers / h. Reals from Cauchy
Cauchy gave a formal definition of a converging sequence. [Shapiro]
     Full Idea: A sequence a1,a2,... of rational numbers is 'Cauchy' if for each rational number ε>0 there is a natural number N such that for all natural numbers m, n, if m>N and n>N then -ε < am - an < ε.
     From: Stewart Shapiro (Thinking About Mathematics [2000], 7.2 n4)
     A reaction: The sequence is 'Cauchy' if N exists.
6. Mathematics / B. Foundations for Mathematics / 1. Foundations for Mathematics
Categories are the best foundation for mathematics [Shapiro]
     Full Idea: There is a dedicated contingent who hold that the category of 'categories' is the proper foundation for mathematics.
     From: Stewart Shapiro (Thinking About Mathematics [2000], 10.3 n7)
     A reaction: He cites Lawvere (1966) and McLarty (1993), the latter presenting the view as a form of structuralism. I would say that the concept of a category will need further explication, and probably reduce to either sets or relations or properties.
6. Mathematics / B. Foundations for Mathematics / 5. Definitions of Number / f. Zermelo numbers
Two definitions of 3 in terms of sets disagree over whether 1 is a member of 3 [Shapiro]
     Full Idea: Zermelo said that for each number n, its successor is the singleton of n, so 3 is {{{null}}}, and 1 is not a member of 3. Von Neumann said each number n is the set of numbers less than n, so 3 is {null,{null},{null,{null}}}, and 1 is a member of 3.
     From: Stewart Shapiro (Thinking About Mathematics [2000], 10.2)
     A reaction: See Idea 645 - Zermelo could save Plato from the criticisms of Aristotle! These two accounts are cited by opponents of the set-theoretical account of numbers, because it seems impossible to arbitrate between them.
6. Mathematics / B. Foundations for Mathematics / 7. Mathematical Structuralism / a. Structuralism
Numbers do not exist independently; the essence of a number is its relations to other numbers [Shapiro]
     Full Idea: The structuralist vigorously rejects any sort of ontological independence among the natural numbers; the essence of a natural number is its relations to other natural numbers.
     From: Stewart Shapiro (Thinking About Mathematics [2000], 10.1)
     A reaction: This seems to place the emphasis on ordinals (what order?) rather than on cardinality (how many?). I am strongly inclined to think that this is the correct view, though you can't really have relations if there is nothing to relate.
A 'system' is related objects; a 'pattern' or 'structure' abstracts the pure relations from them [Shapiro]
     Full Idea: A 'system' is a collection of objects with certain relations among them; a 'pattern' or 'structure' is the abstract form of a system, highlighting the interrelationships and ignoring any features they do not affect how they relate to other objects.
     From: Stewart Shapiro (Thinking About Mathematics [2000], 10.1)
     A reaction: Note that 'ignoring' features is a psychological account of abstraction, which (thanks to Frege and Geach) is supposed to be taboo - but which I suspect is actually indispensable in any proper account of thought and concepts.
6. Mathematics / C. Sources of Mathematics / 6. Logicism / d. Logicism critique
Logicism seems to be a non-starter if (as is widely held) logic has no ontology of its own [Shapiro]
     Full Idea: The thesis that principles of arithmetic are derivable from the laws of logic runs against a now common view that logic itself has no ontology. There are no particular logical objects. From this perspective logicism is a non-starter.
     From: Stewart Shapiro (Thinking About Mathematics [2000], 5.1)
     A reaction: This criticism strikes me as utterly devastating. There are two routes to go: prove that logic does have an ontology of objects (what would they be?), or - better - deny that arithmetic contains any 'objects'. Or give up logicism.
6. Mathematics / C. Sources of Mathematics / 7. Formalism
Term Formalism says mathematics is just about symbols - but real numbers have no names [Shapiro]
     Full Idea: Term Formalism is the view that mathematics is just about characters or symbols - the systems of numerals and other linguistic forms. ...This will cover integers and rational numbers, but what are real numbers supposed to be, if they lack names?
     From: Stewart Shapiro (Thinking About Mathematics [2000], 6.1.1)
     A reaction: Real numbers (such as pi and root-2) have infinite decimal expansions, so we can start naming those. We could also start giving names like 'Harry' to other reals, though it might take a while. OK, I give up.
Game Formalism is just a matter of rules, like chess - but then why is it useful in science? [Shapiro]
     Full Idea: Game Formalism likens mathematics to chess, where the 'content' of mathematics is exhausted by the rules of operating with its language. ...This, however, leaves the problem of why the mathematical games are so useful to the sciences.
     From: Stewart Shapiro (Thinking About Mathematics [2000], 6.1.2)
     A reaction: This thought pushes us towards structuralism. It could still be a game, but one we learned from observing nature, which plays its own games. Chess is, after all, modelled on warfare.
Deductivism says mathematics is logical consequences of uninterpreted axioms [Shapiro]
     Full Idea: The Deductivist version of formalism (sometimes called 'if-thenism') says that the practice of mathematics consists of determining logical consequences of otherwise uninterpreted axioms.
     From: Stewart Shapiro (Thinking About Mathematics [2000], 6.2)
     A reaction: [Hilbert is the source] More plausible than Term or Game Formalism (qv). It still leaves the question of why it seems applicable to nature, and why those particular axioms might be chosen. In some sense, though, it is obviously right.
6. Mathematics / C. Sources of Mathematics / 10. Constructivism / b. Intuitionism
Critics resent the way intuitionism cripples mathematics, but it allows new important distinctions [Shapiro]
     Full Idea: Critics commonly complain that the intuitionist restrictions cripple the mathematician. On the other hand, intuitionist mathematics allows for many potentially important distinctions not available in classical mathematics, and is often more subtle.
     From: Stewart Shapiro (Thinking About Mathematics [2000], 7.1)
     A reaction: The main way in which it cripples is its restriction on talk of infinity ('Cantor's heaven'), which was resented by Hilbert. Since high-level infinities are interesting, it would be odd if we were not allowed to discuss them.
6. Mathematics / C. Sources of Mathematics / 10. Constructivism / c. Conceptualism
Conceptualist are just realists or idealist or nominalists, depending on their view of concepts [Shapiro]
     Full Idea: I classify conceptualists according to what they say about properties or concepts. If someone classified properties as existing independent of language I would classify her as a realist in ontology of mathematics. Or they may be idealists or nominalists.
     From: Stewart Shapiro (Thinking About Mathematics [2000], 2.2.1)
     A reaction: In other words, Shapiro wants to eliminate 'conceptualist' as a useful label in philosophy of mathematics. He's probably right. All thought involves concepts, but that doesn't produce a conceptualist theory of, say, football.
6. Mathematics / C. Sources of Mathematics / 10. Constructivism / d. Predicativism
'Impredicative' definitions refer to the thing being described [Shapiro]
     Full Idea: A definition of a mathematical entity is 'impredicative' if it refers to a collection that contains the defined entity. The definition of 'least upper bound' is impredicative as it refers to upper bounds and characterizes a member of this set.
     From: Stewart Shapiro (Thinking About Mathematics [2000], 1.2)
     A reaction: The big question is whether mathematics can live with impredicative definitions, or whether they threaten to be viciously circular, and undermine the whole enterprise.
7. Existence / C. Structure of Existence / 8. Stuff / a. Pure stuff
I reject talk of 'stuff', and treat it in terms of particles [Inwagen]
     Full Idea: I have a great deal of difficulty with an ontology that includes 'stuffs' in addition to things. ...I prefer to replace talk of sameness of matter with talk of sameness of particles.
     From: Peter van Inwagen (Material Beings [1990], 14)
     A reaction: Van Inwagen is wedded to the idea that reality is composed of 'simples' - even if physicists seem now to talk of 'fields' as much as they do about objects in the fields. Has philosophy yet caught up with Maxwell?
7. Existence / D. Theories of Reality / 10. Vagueness / d. Vagueness as linguistic
Singular terms can be vague, because they can contain predicates, which can be vague [Inwagen]
     Full Idea: Since singular terms can contain predicates, and since vague predicates are common, vague singular terms are common. For 'the tallest man that Sally knows' there are lots of men for whom it is unclear whether Sally knows them.
     From: Peter van Inwagen (Material Beings [1990], 17)
7. Existence / D. Theories of Reality / 10. Vagueness / g. Degrees of vagueness
Stoics applied bivalence to sorites situations, so everyone is either vicious or wholly virtuous [Stoic school, by Williamson]
     Full Idea: The Stoics were prepared to apply bivalence to sorites reasoning, and swallow the consequences. ...For example, they denied that there are degrees of virtue, holding that one is either vicious or perfectly virtuous.
     From: report of Stoic school (fragments/reports [c.200 BCE]) by Timothy Williamson - Vagueness 1.2
     A reaction: Williamson sympathises with this view, but the virtue example suggests to me that it is crazy. One of my objections to traditional religion is the sharp (and wickedly unjust) binary judgement between those who go to heaven and those who go to hell.
7. Existence / E. Categories / 3. Proposed Categories
Stoics have four primary categories: substrates, qualities, dispositions, relative dispositions [Stoic school, by Simplicius]
     Full Idea: Stoics reduce the number of primary categories, some of them new. They divide them into four: substrates [underlying things], qualities [qualified things], dispositions [things in a certain state], and relative dispositions [with respect to something].
     From: report of Stoic school (fragments/reports [c.200 BCE]) by Simplicius - On Aristotle's 'Categories' 1b25 8.66.32
     A reaction: [a precious rare quote on stoic categories] Not sure of the status of the glosses in square brackets. I very much like 'dispositions' as a basic category. Substrates are elusive beasts. Is this list 'objects, qualities, dispositions, relations'?
8. Modes of Existence / D. Universals / 6. Platonic Forms / d. Forms critiques
Platonic Forms are just our thoughts [Stoic school, by Ps-Plutarch]
     Full Idea: The Stoics said that the Ideas [Platonic forms] are our own thoughts.
     From: report of Stoic school (fragments/reports [c.200 BCE]) by Pseudo-Plutarch - On the Doctrine of the Philosophers 882a
     A reaction: That's Plato deftly kicked into touch. I'm with the Stoics.
9. Objects / A. Existence of Objects / 1. Physical Objects
Material objects are in space and time, move, have a surface and mass, and are made of some stuff [Inwagen]
     Full Idea: A thing is a material object if it occupies space and endures through time and can move about in space (literally move, unlike a shadow or wave or reflection) and has a surface and has a mass and is made of a certain stuff or stuffs.
     From: Peter van Inwagen (Material Beings [1990], 01)
     A reaction: It is not at all clear what electrons (which must count for him as 'simples') are made of.
Maybe table-shaped particles exist, but not tables [Inwagen, by Lowe]
     Full Idea: Van Ingwagen holds that although table-shaped collections of particles exist, tables do not.
     From: report of Peter van Inwagen (Material Beings [1990], Ch.13) by E.J. Lowe - The Possibility of Metaphysics 2.3
     A reaction: I find this idea appealing. See the ideas of Trenton Merricks. When you get down to micro-level, it is hard to individuate a table among the force fields, and hard to distinguish a table from a smashed or burnt table. An ontology without objects?
9. Objects / A. Existence of Objects / 6. Nihilism about Objects
Nihilism says composition between single things is impossible [Inwagen]
     Full Idea: Nihilism about objects says there is a Y such that the Xs compose it if and only if there is only one of the Xs.
     From: Peter van Inwagen (Material Beings [1990], 08)
     A reaction: He says that Unger, the best known 'nihilist' about objects, believes a different version - claiming there are composites, but they never make up the ordinary objects we talk about.
If there are no tables, but tables are things arranged tablewise, the denial of tables is a contradiction [Liggins on Inwagen]
     Full Idea: Van Inwagen says 'there are no tables', and 'there are tables' means 'there are some things arranged tablewise'. Presumably 'there are no tables' negates the latter claim, saying no things are arranged tablewise. But he should think that is false.
     From: comment on Peter van Inwagen (Material Beings [1990], 10) by David Liggins - Nihilism without Self-Contradiction 3
     A reaction: Liggins's nice paper shows that Van Inwagen is in a potential state of contradiction when he starts saying that there are no tables, but that there are things arranged tablewise, and that they amount to tables. Liggins offers him an escape.
Actions by artefacts and natural bodies are disguised cooperations, so we don't need them [Inwagen]
     Full Idea: All the activities apparently carried out by shelves and stars and other artefacts and natural bodies can be understood as disguised cooperative activities. And, therefore, we are not forced to grant existence to any artefacts or natural bodies.
     From: Peter van Inwagen (Material Beings [1990], 12)
     A reaction: In 'the crowd tore her to pieces' are we forced to accept the existence of a crowd? We can't say 'Jack tore her to pieces' and 'Jill tore her to pieces'. If a plural quantification is unavoidable, we have to accept the plurality. Perhaps.
9. Objects / B. Unity of Objects / 1. Unifying an Object / b. Unifying aggregates
Every physical thing is either a living organism or a simple [Inwagen]
     Full Idea: The thesis about composition and parthood that I am advocating has far-reaching ontological consequences: that every physical thing is either a living organism or a simple.
     From: Peter van Inwagen (Material Beings [1990], 10)
     A reaction: A 'simple' is a placeholder for anything considered to be a fundamental unit of existence (such as an electron or a quark). This amazingly sharp distinction strikes me as utterly implausible. There is too much in the middle ground.
9. Objects / B. Unity of Objects / 2. Substance / a. Substance
Stoics say matter has qualities, and substance underlies it, with no form or qualities [Stoic school, by Chalcidius]
     Full Idea: Stoics distinguish matter and substance; they say that matter is that which underlies those things which have qualities; however, the primary matter of all things or their most primeval foundation is substance, which is without qualities and unformed.
     From: report of Stoic school (fragments/reports [c.200 BCE]) by Chalcidius - Commentary on Plato's 'Timaeus' 290
     A reaction: In this account, substance begins to sound like Kant's 'noumenon', which is a theoretical concept which has retreated beyond all experience. Stoics were under pressure to cover everything for which the Atomists offered explanations.
9. Objects / B. Unity of Objects / 3. Unity Problems / c. Statue and clay
The statue and lump seem to share parts, but the statue is not part of the lump [Inwagen]
     Full Idea: Those who believe that the statue is distinct from the lump should concede that whatever shares a part with the statue shares a part with the lump but deny that the statue is a part of the lump.
     From: Peter van Inwagen (Material Beings [1990], 05)
     A reaction: Standard mereology says if they share all their parts then they are the same thing, so it is hard to explain how they are 'distinct'. The distinction is only modal - that they could be separated (by squashing, or by part substitution).
If you knead clay you make an infinite series of objects, but they are rearrangements, not creations [Inwagen]
     Full Idea: If you can make a (random) gollyswoggle by accident by kneading clay, then you must be causing the generation and corruption of a series of objects of infinitesimal duration. ...We have not augmented the furniture of the world but only rearranged it.
     From: Peter van Inwagen (Material Beings [1990], 13)
     A reaction: Van Inwagen's final conclusion is a bit crazy, but I am in sympathy with his general scepticism about what sorts of things definitively constitute 'objects'. He overrates simples, and he overrates lives.
9. Objects / C. Structure of Objects / 3. Matter of an Object
I assume matter is particulate, made up of 'simples' [Inwagen]
     Full Idea: I assume in this book that matter is ultimately particulate. Every material being is composed of things that have no proper parts: 'elementary particles' or 'mereological atoms' or 'metaphysical simples'.
     From: Peter van Inwagen (Material Beings [1990], Pref)
     A reaction: It may be that modern physics doesn't support this, if 'fields' is the best term for what is fundamental. Best to treat his book as hypothetical - IF there are just simples, proceed as follows.
9. Objects / C. Structure of Objects / 5. Composition of an Object
If contact causes composition, do two colliding balls briefly make one object? [Inwagen]
     Full Idea: If composition just requires contact, if I cause the cue ball to rebound from the eight ball, do I thereby create a short-lived object shaped like two slightly flattened spheres in contact?
     From: Peter van Inwagen (Material Beings [1990], 03)
     A reaction: [compressed]
If bricks compose a house, that is at least one thing, but it might be many things [Inwagen]
     Full Idea: If composition just requires contact, that tells us that the bricks of a house compose at least one thing; it does not tell us that they also compose at most one thing.
     From: Peter van Inwagen (Material Beings [1990], 04)
9. Objects / C. Structure of Objects / 8. Parts of Objects / a. Parts of objects
I think parthood involves causation, and not just a reasonably stable spatial relationship [Inwagen]
     Full Idea: I propose that parthood essentially involves causation. Too many philosophers have supposed that objects compose something when and only when they stand in some (more or less stable) spatial relationship to one another.
     From: Peter van Inwagen (Material Beings [1990], 09)
     A reaction: I have to say that I like this, even though it comes from a thinker who is close to nihilism about ordinary non-living objects. He goes on to say that only a 'life' provides the right sort of causal relationship.
We can deny whole objects but accept parts, by referring to them as plurals within things [Inwagen, by Liggins]
     Full Idea: Van Inwagen's claim that nothing has parts causes incredulity. ..But the problem is not with endorsing the sentence 'Some things have parts'; it is with interpreting this sentence by means of singular resources rather than plural ones.
     From: report of Peter van Inwagen (Material Beings [1990], 7) by David Liggins - Nihilism without Self-Contradiction
     A reaction: Van Inwagen notoriously denies the existence of normal physical objects. Liggins shows that modern formal plural quantification gives a better way of presenting his theory, by accepting tables and parts of tables as plurals of basic entities.
9. Objects / C. Structure of Objects / 8. Parts of Objects / c. Wholes from parts
Special Composition Question: when is a thing part of something? [Inwagen]
     Full Idea: The Special Composition Question asks, In what circumstances is a thing a (proper) part of something?
     From: Peter van Inwagen (Material Beings [1990], 02)
     A reaction: [He qualifies this formulation as 'misleading'] It's a really nice basic question for the metaphysics of objects.
How is separateness possible, if separated things are always said to be united? [Alexander on Stoic school]
     Full Idea: How could one avoid the inconsistency of saying that adjacent objects that can easily be separated are all the same united with each other, being coherent and never able o be separated from each other without division?
     From: comment on Stoic school (fragments/reports [c.200 BCE]) by Alexander - On Mixture 2.2
     A reaction: In general my sympathies are with Alexander on this. If you abandon all principles of unity apart from unrestricted mereological composition, you save yourself a lot of bother, but you abandon the most useful concepts in ontology.
How is divisibility possible, if stoics say things remain united when they are divided? [Alexander on Stoic school]
     Full Idea: How could the divisibility of bodies be preserved if division is the separation of what is united, and according to them all things stay united with each other, all the same even when they are divided?
     From: comment on Stoic school (fragments/reports [c.200 BCE]) by Alexander - On Mixture 2.2
     A reaction: Evidently the stoics were committed to unrestricted mereological composition (that any parts make a whole, no matter how scattered). Alexander points out that this makes the concept of 'division' of an entity meaningless.
Stoics say wholes are more than parts, but entirely consist of parts [Stoic school, by Sext.Empiricus]
     Full Idea: Stoics say the wholes are not the same as their parts, for a human being is not his hand, nor are they other than their parts, for they do not exist without the parts.
     From: report of Stoic school (fragments/reports [c.200 BCE]) by Sextus Empiricus - Outlines of Pyrrhonism 3.170
     A reaction: 'A human being is not his hand' is not much of a reason. Surely some holistic claim is needed here? The conflict of these two ideas was spotted by Plato.
9. Objects / D. Essence of Objects / 8. Essence as Explanatory
The essence of a star includes the released binding energy which keeps it from collapse [Inwagen]
     Full Idea: I think it is part of the essence of a star that the radiation pressures that oppose the star's tendency to gravitational collapse has its source in the release of no-longer-needed nuclear binding energy when colliding nuclei fuse in the star's hot core.
     From: Peter van Inwagen (Material Beings [1990], 07)
     A reaction: A perfect example of giving the essence of something as the bottom level of its explanation. This even comes from someone who doesn't really believe in stars!
9. Objects / D. Essence of Objects / 11. Essence of Artefacts
The persistence of artifacts always covertly involves intelligent beings [Inwagen]
     Full Idea: Statements that are apparently about the persistence of artifacts make covert reference to the dispositions of intelligent beings to maintain certain arrangements of matter.
     From: Peter van Inwagen (Material Beings [1990], 13)
     A reaction: If you build a self-sustaining windmill that pumps water, that seems to have an identity of its own, apart from the intentions of whoever makes it and repairs it. The function of an artefact is not just the function we want it to have.
9. Objects / E. Objects over Time / 7. Intermittent Objects
When an electron 'leaps' to another orbit, is the new one the same electron? [Inwagen]
     Full Idea: Is the 'new' electron in the lower orbit the one that was in the higher orbit? Physics, as far as I can tell, has nothing to say about this.
     From: Peter van Inwagen (Material Beings [1990], 14)
     A reaction: I suspect that physicists would say that philosophers are worrying about such questions because they haven't grasped the new conceptual scheme that emerged in 1926. The poor mutts insist on hanging on to 'objects'.
9. Objects / E. Objects over Time / 9. Ship of Theseus
If you reject transitivity of vague identity, there is no Ship of Theseus problem [Inwagen]
     Full Idea: If you have rejected the Principle of the Transitivity of (vague) Identity, it is hard to see how the problem of the Ship of Theseus could arise.
     From: Peter van Inwagen (Material Beings [1990], 18)
     A reaction: I think this may well be the best solution to the whole problem
9. Objects / F. Identity among Objects / 1. Concept of Identity
We should talk of the transitivity of 'identity', and of 'definite identity' [Inwagen]
     Full Idea: In some contexts, the principle of 'the transitivity of identity' should be called 'the transitivity of definite identity'.
     From: Peter van Inwagen (Material Beings [1990], 18)
     A reaction: He is making room for a person to retain identity despite having changed. Applause from me.
10. Modality / B. Possibility / 1. Possibility
A proposition is possible if it is true when nothing stops it being true [Stoic school, by Diog. Laertius]
     Full Idea: That proposition is possible which admits of being true, if external factors do not prevent it from being true, for example, 'Diocles is alive'.
     From: report of Stoic school (fragments/reports [c.200 BCE]) by Diogenes Laertius - Lives of Eminent Philosophers 07.75
     A reaction: Well that's different. So every unprevented possibility will occur tomorrow. Any possibility that does not occur tomorrow must have been prevented in some way. Whatever does occur prevents innumerable other things from occurring. Your turn…
10. Modality / B. Possibility / 8. Conditionals / c. Truth-function conditionals
Conditionals are false if the falsehood of the conclusion does not conflict with the antecedent [Stoic school, by Diog. Laertius]
     Full Idea: A conditional is true if the opposite of the conclusion conflicts with the antecedent, and false if it doesn't conflict. Thus 'If it is day, Dion is walking' is false, because 'Dion is not walking' does not conflict with 'It is day'.
     From: report of Stoic school (fragments/reports [c.200 BCE]) by Diogenes Laertius - Lives of Eminent Philosophers 07.73
     A reaction: For the two to conflict there must be some connection in subject matter, which is not the case if the mere falsehood of the conclusion (from a true premise) falsifies the conditional. This seems like a rather good account.
10. Modality / C. Sources of Modality / 5. Modality from Actuality
Actuality proves possibility, but that doesn't explain how it is possible [Inwagen]
     Full Idea: A proof of actuality is a proof of possibility, but that does not invariably explain the possibility whose existence it demonstrates, for we may know that a certain thing is actual (and hence possible) but have no explanation of how it could be possible.
     From: Peter van Inwagen (Material Beings [1990], 12)
     A reaction: I like this, because my project is to see all of philosophy in terms of explanation rather than of description.
10. Modality / E. Possible worlds / 3. Transworld Objects / c. Counterparts
Counterparts reduce counterfactual identity to problems about similarity relations [Inwagen]
     Full Idea: Counterpart Theory essentially reduces all problems about counterfactual identity to problems about choosing appropriate similarity relations. That is, Counterpart Theory essentially eliminates problems of counterfactual identity as such.
     From: Peter van Inwagen (Material Beings [1990], 14)
10. Modality / E. Possible worlds / 3. Transworld Objects / e. Possible Objects
A merely possible object clearly isn't there, so that is a defective notion [Inwagen]
     Full Idea: The notion of a merely possible object is an even more defective notion than the notion of a borderline object; after all, a merely possible object is an object that definitely isn't there.
     From: Peter van Inwagen (Material Beings [1990], 19)
Merely possible objects must be consistent properties, or haecceities [Inwagen]
     Full Idea: Talk of merely possible objects may be redeemed in either maximally consistent sets of properties or in haecceities.
     From: Peter van Inwagen (Material Beings [1990], 19)
11. Knowledge Aims / A. Knowledge / 1. Knowledge
Knowledge is a secure grasp of presentations which cannot be reversed by argument [Stoic school, by Diog. Laertius]
     Full Idea: Knowledge itself, say the stoics, is either a secure grasp or a disposition in the reception of presentations not reversible by argument.
     From: report of Stoic school (fragments/reports [c.200 BCE]) by Diogenes Laertius - Lives of Eminent Philosophers 07.47
     A reaction: Helpful, but not enough. Fools hold secure grasps which cannot be refuted, as far as they are concerned. Consensus needed. Falsification? The truth-bearer is a 'presentation' (an appearance), which is different from modern accounts.
11. Knowledge Aims / A. Knowledge / 4. Belief / b. Elements of beliefs
Two sorts of opinion: either poorly grounded belief, or weak belief [Stoic school, by Stobaeus]
     Full Idea: There are two kinds of opinion: one is assent to something which is not graspable; the other is weak belief.
     From: report of Stoic school (fragments/reports [c.200 BCE]) by John Stobaeus - Anthology 2.11m
     A reaction: Strong belief usually qualifies as knowledge. The Greek 'opinion' and 'belief' don't exactly map onto the modern words. This idea covers both the subjective aspect of belief (its strength) and its objective aspect (its grounding).
12. Knowledge Sources / A. A Priori Knowledge / 1. Nature of the A Priori
There are non-sensible presentations, which come to us through the intellect [Stoic school, by Diog. Laertius]
     Full Idea: Stoics say some presentations are sensible, some non-sensible. Those received through the sense organs are sensible; non-sensible are those which come through the intellect, for example, presentations of incorporeals and other things grasped by reason.
     From: report of Stoic school (fragments/reports [c.200 BCE]) by Diogenes Laertius - Lives of Eminent Philosophers 07.51
     A reaction: The a priori used to be metaphysics (a world of truths), and in modern times is epistemology (a mode of justification), but here it is just a mode of experience, which is not, it seems, necessarily true.
12. Knowledge Sources / A. A Priori Knowledge / 3. Innate Knowledge / c. Tabula rasa
Stoics say we are born like a blank sheet of paper; the first concepts on it are sensations [Stoic school, by Ps-Plutarch]
     Full Idea: The Stoics say when a human being is born, the leading part of his soul is like a sheet of paper ready for being written on. On this he inscribes every one of his conceptions. The first manner of writing on it is through the senses.
     From: report of Stoic school (fragments/reports [c.200 BCE]) by Pseudo-Plutarch - On the Doctrine of the Philosophers 900a
     A reaction: This may not be dogmatic empiricism, because later inscriptions on the sheet could be purely a priori.
At birth the soul is a blank sheet ready to be written on [Stoic school, by Aetius]
     Full Idea: When a man is born, the Stoics say, he has the commanding-part of his soul like a sheet of paper reading for writing upon; on this he inscribes each one of his conceptions.
     From: report of Stoic school (fragments/reports [c.200 BCE]) by Aetius - fragments/reports 4.11
     A reaction: This appears to be the origin of the concept of the 'tabula rasa', which resurfaces in empirical thought, in Locke and elsewhere. Notice that 'he' inscribes on the paper, rather than raw experience doing the job. The natural light of reason can do it.
12. Knowledge Sources / B. Perception / 2. Qualities in Perception / d. Secondary qualities
Non-graspable presentations are from what doesn't exist, or are not clear and distinct [Stoic school, by Diog. Laertius]
     Full Idea: The non-graspable presentation is either not from an existing object or from an existing object but not in accordance with it; it is neither clear nor well stamped (i.e. distinct).
     From: report of Stoic school (fragments/reports [c.200 BCE]) by Diogenes Laertius - Lives of Eminent Philosophers 07.46
     A reaction: This sounds exactly like Locke's account of secondary qualities, at least as interpreted by Peter Alexander. That is, they are genuine qualities of things, but misleading, in a way that primary qualities are not.
12. Knowledge Sources / B. Perception / 5. Interpretation
Stoic perception is a presentation to which one voluntarily assents [Stoic school, by Stobaeus]
     Full Idea: The Stoics did not make sense-perception consist in presentation alone but made its substance depend on assent; for perception is an assent to a perceptual presentation, the assent being voluntary.
     From: report of Stoic school (fragments/reports [c.200 BCE]) by John Stobaeus - Anthology 1.49.25
     A reaction: [Stobaeus cites Porphyry's De Anima] Thus you only perceive a hallucination if you do not realise that it is false. This is more subjective than I would want to be. If you only think you perceive, but you are wrong, then I say you don't perceive.
12. Knowledge Sources / C. Rationalism / 1. Rationalism
Rationalism tries to apply mathematical methodology to all of knowledge [Shapiro]
     Full Idea: Rationalism is a long-standing school that can be characterized as an attempt to extend the perceived methodology of mathematics to all of knowledge.
     From: Stewart Shapiro (Thinking About Mathematics [2000], 1.1)
     A reaction: Sometimes called 'Descartes's Dream', or the 'Enlightenment Project', the dream of proving everything. Within maths, Hilbert's Programme aimed for the same certainty. Idea 22 is the motto for the opposition to this approach.
12. Knowledge Sources / D. Empiricism / 1. Empiricism
All our concepts come from experience, directly, or by expansion, reduction or compounding [Stoic school, by Sext.Empiricus]
     Full Idea: In general one can find nothing in our conceptions that is not known to oneself in direct experience. For it is grasped either by similarity to what is revealed in direct experience, or by expansion or reduction or compounding.
     From: report of Stoic school (fragments/reports [c.200 BCE]) by Sextus Empiricus - Against the Mathematicians 8.58
     A reaction: Although the stoics allow for purely a priori knowledge, this quotation sounds comprehensively empirical.
13. Knowledge Criteria / B. Internal Justification / 1. Epistemic virtues
Dialectic is a virtue which contains other virtues [Stoic school, by Diog. Laertius]
     Full Idea: Dialectic itself is necessary, and is a virtue which contains other virtues.
     From: report of Stoic school (fragments/reports [c.200 BCE]) by Diogenes Laertius - Lives of Eminent Philosophers 07.46
     A reaction: Presumable the virtues which are 'contained' are the whole panoply of other intellectual virtues. These will be virtues of intellectual character (Zagzebski), not virtues of processes (Sosa).
13. Knowledge Criteria / C. External Justification / 4. Tracking the Facts
For Stoics knowledge is an assertion which never deviates from the truth [Stoic school, by Diog. Laertius]
     Full Idea: Stoics define knowledge as an assertion or safe comprehension or habit, which, in the perception of what is seen, never deviates from the truth.
     From: report of Stoic school (fragments/reports [c.200 BCE]) by Diogenes Laertius - Lives of Eminent Philosophers 07.1.25
     A reaction: Sounds somewhere between Nozick's 'tracking the truth' and Goldman's 'reliable source'. If the world is a flux, then presumably it is right that knowledge should fluctuate too.
14. Science / A. Basis of Science / 2. Demonstration
Demonstration derives what is less clear from what is clear [Stoic school, by Diog. Laertius]
     Full Idea: Demonstration is an argument which by means of things more clearly grasped concludes to something that is less clearly grasped.
     From: report of Stoic school (fragments/reports [c.200 BCE]) by Diogenes Laertius - Lives of Eminent Philosophers 07.45
     A reaction: In Aristotle demonstration seems to concern physical sciences, but this stoic account makes it sound like pure logic proof. This is why all logic tends to start from atomic sentences, because they are clearest.
15. Nature of Minds / A. Nature of Mind / 1. Mind / a. Mind
The Stoics think that soul in the narrow sense is nothing but reason [Stoic school, by Frede,M]
     Full Idea: The Stoics think that we are exclusively moved by reason, because the soul in a narrow sense is nothing but reason.
     From: report of Stoic school (fragments/reports [c.200 BCE]) by Michael Frede - Intro to 'Rationality in Greek Thought' p.8
     A reaction: Presumably that means that desires and perceptions are not part of the 'narrow' soul. This is the culmination of Socratic intellectualism.
15. Nature of Minds / A. Nature of Mind / 1. Mind / c. Features of mind
Eight parts of the soul: five senses, seeds, speech and reason [Stoic school, by Diog. Laertius]
     Full Idea: The stoics say there are eight parts of the soul: the five senses, the spermatic principle is us, the vocal part, and the reasoning part.
     From: report of Stoic school (fragments/reports [c.200 BCE]) by Diogenes Laertius - Lives of Eminent Philosophers 07.155
15. Nature of Minds / A. Nature of Mind / 2. Psuche
Division of the soul divides a person, reducing responsibility for the nonrational part [Stoic school, by Frede,M]
     Full Idea: According to the Stoics, the division of the soul threatens the unity of the person and obscures the responsibility we have for our supposedly nonrational desires.
     From: report of Stoic school (fragments/reports [c.200 BCE]) by Michael Frede - A Free Will 3
     A reaction: Does this imply the concept of a 'person', if it places great store by unity? Disagreement over mental unity is one of the great threads running through philosophy. See Nietzsche on 'drives' for the rival view.
Stoics say the soul is a mixture of air and fire [Stoic school, by Galen]
     Full Idea: The Stoic view is clear: the substance of soul comes about through some mixture of air and fire.
     From: report of Stoic school (fragments/reports [c.200 BCE]) by Galen - The soul's dependence on the body Kiv.4.784
     A reaction: Most accounts seem to neglect the role of air (whatever that might be).
15. Nature of Minds / C. Capacities of Minds / 1. Faculties
Our conceptions arise from experience, similarity, analogy, transposition, composition and opposition [Stoic school, by Diog. Laertius]
     Full Idea: Some conceptions are conceived on the basis of direct experience, some on the basis of similarity, some on the basis of analogy, some on the basis of transposition, some on the basis of composition, and some on the basis of opposition.
     From: report of Stoic school (fragments/reports [c.200 BCE]) by Diogenes Laertius - Lives of Eminent Philosophers 07.52
     A reaction: These are examples of what I think of as 'philosophical faculties', probably not mentioned by either psychologists or neuro-scientists, but seen by philosophers as necessary preconditions for certain basic operations of thought.
16. Persons / A. Concept of a Person / 4. Persons as Agents
For Stoics the true self is defined by what I can be master of [Stoic school, by Foucault]
     Full Idea: For the Stoics, the true self is defined only by what I can be master of.
     From: report of Stoic school (fragments/reports [c.200 BCE]) by Michel Foucault - On the Genealogy of Ethics
     A reaction: Interesting. This ties the self to the will - indeed, it almost identifies the self with the will. Why is the self the parts that are mastered, rather than the part that does the mastering? I master my shoes, but they are not me.
16. Persons / F. Free Will / 3. Constraints on the will
Stoics expanded the idea of compulsion, and contracted what counts as one's own actions [Stoic school, by Frede,M]
     Full Idea: With Stoics, and in its wake, we get an enormous expansion of what counts as being forced [biazesthai] or compelled or made to do something, and correspondingly an enormous contraction of what counts as an action of one's own.
     From: report of Stoic school (fragments/reports [c.200 BCE]) by Michael Frede - A Free Will 5
     A reaction: The key idea seems to be setting the bar higher for being in control, which eventually leads to the idea of free will. Frede says this does not contract responsibility, because what controls us can be our own fault.
16. Persons / F. Free Will / 5. Against Free Will
The free will problem was invented by the Stoics [Stoic school, by Berlin]
     Full Idea: The free-will problem was invented by the Stoics.
     From: report of Stoic school (fragments/reports [c.200 BCE]) by Isaiah Berlin - The Roots of Romanticism Ch.4
     A reaction: Compare Ideas 6018 and 7814. There is no sign of the problem in Book 3 of Aristotle's Ethics. This is crucial, since I consider the problem to be totally bogus.
16. Persons / F. Free Will / 6. Determinism / b. Fate
The nearest to ancient determinism is Stoic fate, but that is controlled by a sympathetic God [Stoic school, by Frede,M]
     Full Idea: The doctrine of antiquity nearest to physical determinism was the Stoic doctrine of fate. But their fate is the work of an agent, and is predetermined in part with regard to us, and even seems be contingent on anticipated human choices.
     From: report of Stoic school (fragments/reports [c.200 BCE]) by Michael Frede - A Free Will Intro
     A reaction: [compressed] The gist is that this is the most determinist the ancients ever get (e.g. the swerve of Epicurus), and it is not very determinist at all, in comparison with modern Laplacean physical determinism. Late antiquity determinism was stronger.
18. Thought / A. Modes of Thought / 3. Emotions / b. Types of emotion
Stoics classify passions according to the opinion of good and bad which they imply [Stoic school, by Taylor,C]
     Full Idea: The Stoics classified the passions according to the implicit (and erroneous) opinions about the good and bad that they contained.
     From: report of Stoic school (fragments/reports [c.200 BCE]) by Charles Taylor - Sources of the Self §8
     A reaction: This doesn't sound very promising, since nearly all emotions can be put to either a good or a bad use
18. Thought / A. Modes of Thought / 3. Emotions / e. Basic emotions
There are four basic emotions: pleasure or delight, distress, appetite, and fear [Stoic school, by Cicero]
     Full Idea: The Stoics named four basic emotions: pleasure or delight, distress, appetite, and fear
     From: report of Stoic school (fragments/reports [c.200 BCE]) by M. Tullius Cicero - Tusculan Disputations iv.13-15
     A reaction: 'Distress' sounds too vague to do the job of explaining anything. Getting them down to four suggests an extreme desire to simplify such things.
18. Thought / A. Modes of Thought / 6. Judgement / a. Nature of Judgement
Stoics said that correct judgement needs an invincible criterion of truth [Stoic school, by Fogelin]
     Full Idea: Stoic epistemologists held that to judge correctly, one must be in possession of a proper criterion of truth - a test that provides invincible evidence of the truth of some belief.
     From: report of Stoic school (fragments/reports [c.200 BCE]) by Robert Fogelin - Walking the Tightrope of Reason Ch.4
     A reaction: It seems that the Stoics were the first to 'set the bar too high', and inevitably drew the sceptical response that there is no such criterion. The polarisation might go further back, to Parmenides' One (known for certain by reason) and Heraclitus's Flux.
18. Thought / D. Concepts / 1. Concepts / a. Nature of concepts
Concepts are intellectual phantasms [Stoic school, by Ps-Plutarch]
     Full Idea: A concept is a phantasm of the intellect of a rational animal.
     From: report of Stoic school (fragments/reports [c.200 BCE]) by Pseudo-Plutarch - On the Doctrine of the Philosophers 900c
     A reaction: No doubt they assume that the brutes are devoid of all concepts, but that makes it hard to explain their behaviour.
19. Language / C. Assigning Meanings / 3. Predicates
Predicates are incomplete 'lekta' [Stoic school, by Diog. Laertius]
     Full Idea: Stoics place predicates among the incomplete 'lekta'.
     From: report of Stoic school (fragments/reports [c.200 BCE]) by Diogenes Laertius - Lives of Eminent Philosophers 07.63
     A reaction: This seems to be the modern Fregean logician's concept of a predicate.
19. Language / D. Propositions / 4. Mental Propositions
Humans have rational impressions, which are conceptual, and are true or false [Stoic school, by Frede,M]
     Full Idea: For Stoics, all human impressions differ from animals in that they are rational. …They are impressions that something is the case, and hence are true or false. Their formation involves the use of concepts, and are thus also called 'thoughts' [noeseis].
     From: report of Stoic school (fragments/reports [c.200 BCE]) by Michael Frede - A Free Will 3
     A reaction: This is a pretty accurate account of my notion of a 'proposition'. Since many animals make judgements, I take them to entertain non-verbal propositions. I assume there are also propositions which are more internal, and thus not 'impressions'.
19. Language / F. Communication / 1. Rhetoric
Rhetoric has three types, four modes, and four sections [Stoic school, by Diog. Laertius]
     Full Idea: Stoics say rhetoric is tripartite. Part is deliberative, part forensic, part encomiastic. It is divided into invention, diction, organisation, and delivery. Rhetorical speech is divided into the introduction, exposition, counterargument and conclusion.
     From: report of Stoic school (fragments/reports [c.200 BCE]) by Diogenes Laertius - Lives of Eminent Philosophers 07.42-3
     A reaction: The last bit is quite a good guide for a philosophical paper.
20. Action / B. Preliminaries of Action / 2. Willed Action / a. Will to Act
Earlier Stoics speak of assent, but not of choice, let alone of a will [Stoic school, by Frede,M]
     Full Idea: Stoics [before Epictetus] have a notion of assent, and hence the appropriate notion of a willing, but we do not yet have a notion of a choice [prohairesis], let alone of a will.
     From: report of Stoic school (fragments/reports [c.200 BCE]) by Michael Frede - A Free Will 3
     A reaction: The assent is just giving in to a desire, which is either rational or irrational. Choice implies a second-level thinking, of weighing the two desires. The will would then be a faculty which can do this (which seems to be the invention of Epictetus).
20. Action / C. Motives for Action / 4. Responsibility for Actions
Stoics said responsibility depends on rationality [Stoic school, by Sorabji]
     Full Idea: It is the Stoics who made responsibility depend on rationality.
     From: report of Stoic school (fragments/reports [c.200 BCE]) by Richard Sorabji - Rationality 'Ethical'
     A reaction: Aristotle's account of responsibility in 'Ethics' needs a high degree of rationality, far beyond even a rational non-human animal. And no one thinks small children are responsible.
21. Aesthetics / C. Artistic Issues / 7. Art and Morality
Stoics use 'kalon' (beautiful) as a synonym for 'agathon' (good) [Bury on Stoic school]
     Full Idea: The Stoics used 'kalon' [fair, i.e. beautiful] as a synonym for 'agathon' [good]
     From: comment on Stoic school (fragments/reports [c.200 BCE]) by R.G.Bury - notes on Sextus Empiricus 69:245
     A reaction: I consider this to be a very important idea, which has been lost in modern moral philosophy - even in modern virtue theory. I've seen the suggestion that the best translation of 'kalon' is 'Wow!'. Imagine deeds that elicit 'Wow!'.
22. Metaethics / A. Ethics Foundations / 2. Source of Ethics / b. Rational ethics
Stoics say that folly alone is evil [Stoic school, by Sext.Empiricus]
     Full Idea: The Stoics say that folly alone is evil.
     From: report of Stoic school (fragments/reports [c.200 BCE]) by Sextus Empiricus - Against the Ethicists (one book) II.90
     A reaction: This is Socrates' intellectualist view of weakness of will. Is the evil in the succumbing to a temptation, or in the intellectual error that leads to it? 'Folly' in English is stupid action, not just stupid belief.
22. Metaethics / B. Value / 1. Nature of Value / a. Nature of value
Prime values apply to the life in agreement; useful values apply to the natural life [Stoic school, by Diog. Laertius]
     Full Idea: Stoics say one sort of value is a contribution to the life in agreement, which applies to every good. Another is an intermediate potential or usefulness (such as wealth or health) contributing to the life according to nature.
     From: report of Stoic school (fragments/reports [c.200 BCE]) by Diogenes Laertius - Lives of Eminent Philosophers 07.105
     A reaction: Assessing value by what it contributes to is interesting. There is also the appraiser's value.
22. Metaethics / B. Value / 1. Nature of Value / d. Subjective value
The appraiser's value is what is set by someone experienced in the facts [Stoic school, by Diog. Laertius]
     Full Idea: Another sense of value is the appraiser's value, which someone experienced in the facts would set, as when one says that wheat is exchanged for barley with a mule thrown in.
     From: report of Stoic school (fragments/reports [c.200 BCE]) by Diogenes Laertius - Lives of Eminent Philosophers 07.105
     A reaction: No relativist nonsense here. Conventional values are set by experts, not by hoi polloi.
22. Metaethics / B. Value / 1. Nature of Value / f. Ultimate value
The goal is to live consistently with the constitution of a human being [Stoic school, by Clement]
     Full Idea: More recent stoics defined the goal as to live consistently with the constitution of a human being.
     From: report of Stoic school (fragments/reports [c.200 BCE]) by Clement - Stromates 2.21.129.6
     A reaction: This sounds more Aristotelian than the classic stoics. The obvious problem is the nasty side of human nature. At least Aristotle adds something like 'when it is functioning well, particularly in social situations'.
22. Metaethics / B. Value / 2. Values / d. Health
Stoics said health is an 'indifferent', but they still considered it preferable [Stoic school, by Pormann]
     Full Idea: For the Stoics bodily health belongs in the 'indifferent [adiaphoron]' category: it does not matter if one is healthy. And yet, they created a subcategory of the 'preferable indifferent [adiaphoron proegmenon]', under which health falls.
     From: report of Stoic school (fragments/reports [c.200 BCE]) by Peter E. Pormann - Medical Conceptions of Health pre-Renaissance p.45
     A reaction: You have to be pretty tough to consider ill-health as an indifferent. The only good may be virtue, but the platonic tradition says virtue is a sort of mental health.
The health of the soul is a good blend of beliefs [Stoic school, by Stobaeus]
     Full Idea: The health of the soul is a good blend of the beliefs in the soul.
     From: report of Stoic school (fragments/reports [c.200 BCE]) by John Stobaeus - Anthology 2.05b04
     A reaction: When I write my great book, this may well be its epigraph. I presume it means 'wisdom is the health of the soul'.
22. Metaethics / B. Value / 2. Values / f. Altruism
Stoic morality says that one's own happiness will lead to impartiality [Stoic school, by Annas]
     Full Idea: Stoics begin ethics with concern for one's own happiness, and end up claiming that in morality one will be indifferent between one's own interests and those of 'the remote Mysian'.
     From: report of Stoic school (fragments/reports [c.200 BCE]) by Julia Annas - The Morality of Happiness 2.7
     A reaction: Makes sense, if pursuing our own happiness is doomed, and the best we can manage is indifference.
22. Metaethics / B. Value / 2. Values / g. Love
Virtuous men do not feel sexual desire, which merely focuses on physical beauty [Stoic school, by Diog. Laertius]
     Full Idea: Sexual love is a desire which does not afflict virtuous men, for it is an effort to gain love resulting from the appearance of physical beauty.
     From: report of Stoic school (fragments/reports [c.200 BCE]) by Diogenes Laertius - Lives of Eminent Philosophers 07.113
     A reaction: That is a surprising interpretation of the slogan 'live according to nature'. I would have thought it was factually incorrect, since many objects of human lust rank fairly low in the scale of beauty. Sex is a tough duty if you don't desire it.
22. Metaethics / B. Value / 2. Values / h. Fine deeds
Stoicism was an elitist option to lead a beautiful life [Stoic school, by Foucault]
     Full Idea: Stoicism offered a personal choice for a small elite. The reason for making this choice was the will to live a beautiful life, and to leave to others memories of a beautiful existence.
     From: report of Stoic school (fragments/reports [c.200 BCE]) by Michel Foucault - On the Genealogy of Ethics p.254
     A reaction: This resurfaces in the late nineteenth century aesthetic movement ("Forget living - our servants can do that for us"). I see no reason why this should not be an ideal held up for all human beings, though pleasure-seekers will probably reject it.
22. Metaethics / C. The Good / 1. Goodness / b. Types of good
Final goods: confidence, prudence, freedom, enjoyment and no pain, good spirits, virtue [Stoic school, by Diog. Laertius]
     Full Idea: Stoics say that confidence and prudence and freedom and enjoyment and good spirits and freedom from pain and every virtuous action are final (as opposed to instrumental) goods.
     From: report of Stoic school (fragments/reports [c.200 BCE]) by Diogenes Laertius - Lives of Eminent Philosophers 07.96
     A reaction: An interesting and unusual list. I've never seen 'confidence' or 'good spirits' mentioned. 'Freedom' is also unusual, but probably just means not being enslaved.
22. Metaethics / C. The Good / 2. Happiness / a. Nature of happiness
Happiness for the Stoics was an equable flow of life [Stoic school, by Sext.Empiricus]
     Full Idea: Happiness is defined by Zeno and Cleanthes and Chrysippus as 'an equable flow of life'.
     From: report of Stoic school (fragments/reports [c.200 BCE]) by Sextus Empiricus - Against the Ethicists (one book) II.30
     A reaction: These are the great Stoics. Sounds a bit dull. The old Chinese curse: 'may you live in interesting times'. An equable life could be achieve by never attempting anything, and never getting involved in anything. I don't agree with this idea.
22. Metaethics / C. The Good / 2. Happiness / d. Routes to happiness
Happiness is the end and goal, achieved by living virtuously, in agreement, and according to nature [Stoic school, by Stobaeus]
     Full Idea: Stoics say that being happy is the goal for the sake of which everything else is done, for the sake of nothing else; and this consists in living according to virtue, in living in agreement, and (which is the same thing) in living according to nature.
     From: report of Stoic school (fragments/reports [c.200 BCE]) by John Stobaeus - Anthology 2.06e
     A reaction: The best summary I have found of the main stoic goal. Stoics are eudaimonists. The full stoic story must explain how virtue, agreement and nature fit together into a coherent whole.
22. Metaethics / C. The Good / 3. Pleasure / c. Value of pleasure
Stoics say pleasure is at most a byproduct of finding what is suitable for us [Stoic school, by Diog. Laertius]
     Full Idea: Stoics say that pleasure is, if anything, a byproduct which supervenes when nature itself, on its own, seeks out and acquires what is suitable to the animal's constitution.
     From: report of Stoic school (fragments/reports [c.200 BCE]) by Diogenes Laertius - Lives of Eminent Philosophers 07.86
     A reaction: It would be nice if pleasure were just an indicator that you are successfully living according to nature. Human refinement of alcohol and opium have rather undermined that view (but note 'on its own'). Note also the parenthetical 'if anything'.
22. Metaethics / C. The Good / 3. Pleasure / f. Dangers of pleasure
Rapture is a breakdown of virtue [Stoic school, by Diog. Laertius]
     Full Idea: Rapture is a breakdown of virtue.
     From: report of Stoic school (fragments/reports [c.200 BCE]) by Diogenes Laertius - Lives of Eminent Philosophers 07.114
     A reaction: I take rapture to be judged as the highest good by many romantics. Could rapture be confined and ring-fenced by virtue? Does rapture include great art?
23. Ethics / C. Virtue Theory / 1. Virtue Theory / a. Nature of virtue
If humans are citizens of the world (not just a state) then virtue is all good human habits [Stoic school, by Mautner]
     Full Idea: If, as in Stoic and later systems, human beings are regarded as citizens of the world and not only of a city-state, general justice will include all the habits and dispositions of a good human being.
     From: report of Stoic school (fragments/reports [c.200 BCE]) by Thomas Mautner - Penguin Dictionary of Philosophy p.289
     A reaction: I like this a lot, because it addresses the key problem of virtue theory, the problem of 'the Nazi virtues'. The Nazis might be seen (by some) as 'good' Germans, but they were obviously appalling Europeans, and that is what matters.
23. Ethics / C. Virtue Theory / 2. Elements of Virtue Theory / f. The Mean
An appropriate action is one that can be defended, perhaps by its consistency. [Stoic school, by Diog. Laertius]
     Full Idea: An appropriate action, say the stoics, is that which, when done, admits of a reasonable defence, such as what is consistent in life, and this extends also to plants and animals.
     From: report of Stoic school (fragments/reports [c.200 BCE]) by Diogenes Laertius - Lives of Eminent Philosophers 07.107
     A reaction: I love [Zeno's] word 'appropriate' here, since that strikes me as greatly clarifying the Aristotelian doctrine of the mean. In fact I love the whole of this idea. Appropriate actions can be defended. Cf T.Scanlon. Consistency is a good defence.
23. Ethics / C. Virtue Theory / 3. Virtues / e. Honour
Honour is just, courageous, orderly or knowledgeable. It is praiseworthy, or functions well [Stoic school, by Diog. Laertius]
     Full Idea: Four forms of the honourable: just, courageous, orderly, knowledgeable. The honourable means what makes it possessor praiseworthy; or what is naturally suited for its function; or what adorns its possessor, since we say only the wise man is honourable.
     From: report of Stoic school (fragments/reports [c.200 BCE]) by Diogenes Laertius - Lives of Eminent Philosophers 07.100
     A reaction: Thus we honour successful judges, soldiers, administrators and scholars. Oh, and footballers. Paul Macartney said 'show me someone famous, and I'll show you someone who is good at their job.
23. Ethics / C. Virtue Theory / 3. Virtues / g. Contemplation
The Stoics rejected entirely the high value that had been placed on contemplation [Stoic school, by Taylor,C]
     Full Idea: The Stoics broke with both Plato and Aristotle by rejecting altogether the value of contemplation.
     From: report of Stoic school (fragments/reports [c.200 BCE]) by Charles Taylor - Sources of the Self §6.3
     A reaction: Interesting. This affects the status of philosophy, and rejects the aspiration of humans to become like gods.
23. Ethics / C. Virtue Theory / 4. External Goods / a. External goods
Stoics do not despise external goods, but subject them to reason, and not to desire [Taylor,R on Stoic school]
     Full Idea: Unlike the Cynics, the Stoics did not carry their indifference to conventional goods to outright scorn and rejection of them. They only insisted that such goods should not be the object of desire, since desire is something opposed to reason.
     From: comment on Stoic school (fragments/reports [c.200 BCE]) by Richard Taylor - Virtue Ethics: an Introduction Ch.8
     A reaction: The Stoic view would appear to be derived from Aristotle, who only wants external goods insofar as they can support the life of virtue (as in needing money to be generous). Perhaps the Cynics made the Stoics a bit more puritanical than Aristotle.
Crafts like music and letters are virtuous conditions, and they accord with virtue [Stoic school, by Stobaeus]
     Full Idea: Stoics call 'practices' the love of music, letters, horses, hunting and crafts. They are not knowledge, but virtuous conditions, and they say that only the wise man is a music lover and a lover of letters. Crafts lead to what accords with virtue.
     From: report of Stoic school (fragments/reports [c.200 BCE]) by John Stobaeus - Anthology 2.05b11
     A reaction: I like the distinction between virtue and 'virtuous conditions'. It might correspond to the eighteenth century idea of good taste, or the later idea of having a liberal education.
23. Ethics / D. Deontological Ethics / 2. Duty
For Stoics, obligations are determined by social role [Taylor,R on Stoic school]
     Full Idea: In keeping with what was generally assumed in their culture, Stoics thought obligations are determined by role or function.
     From: comment on Stoic school (fragments/reports [c.200 BCE]) by Richard Taylor - Virtue Ethics: an Introduction Ch.8
     A reaction: We still recognise our obligations as partly in what-we-are-paid-to-do, but that is a contractual obligation. We also accept obligations arising from a family role, such as 'parent'. We are merely no longer impressed by traditional aristocratic hierarchy.
24. Political Theory / A. Basis of a State / 1. A People / a. Human distinctiveness
Man is distinguished by knowing conditional truths, because impressions are connected [Stoic school, by Long]
     Full Idea: Stoics say man differs from irrational animals because of internal speech ...and in virtue of impressions created by inference and combination. Because of this man grasps 'signal', of the form 'If this, then that', which follows from the nature of man.
     From: report of Stoic school (fragments/reports [c.200 BCE]) by A.A. Long - Hellenistic Philosophy 4.3.1
     A reaction: [In Sextus, Adv.Math 8.275-] This is unusual. The distinctive feature of humans is their ability to assert conditionals (because they see connections - or associations - among their impressions). Nice thought.
24. Political Theory / B. Nature of a State / 3. Constitutions
Stoics favour a mixture of democracy, monarchy and aristocracy [Stoic school, by Diog. Laertius]
     Full Idea: Stoics say the best political constitution is a mixed one, combined of democracy, and kingly power, and aristocracy.
     From: report of Stoic school (fragments/reports [c.200 BCE]) by Diogenes Laertius - Lives of Eminent Philosophers 07.Ze.66
24. Political Theory / D. Ideologies / 1. Ideology
The Stoics saw the whole world as a city [Stoic school, by Long]
     Full Idea: The Stoics conceived of the world itself as a kind of city.
     From: report of Stoic school (fragments/reports [c.200 BCE]) by A.A. Long - Hellenistic Philosophy 1
     A reaction: Interesting. Not the same as a cosmopolitan acceptance of a multitude of varied cultures. The most remote and unusual culture is seen as a distant suburb of our culture.
The best government blends democracy, monarchy and aristocracy [Stoic school, by Diog. Laertius]
     Full Idea: Stoics say the best form of government is a blend of democracy and monarchy and aristocracy.
     From: report of Stoic school (fragments/reports [c.200 BCE]) by Diogenes Laertius - Lives of Eminent Philosophers 07.131
     A reaction: Sounds like nineteenth century Britain, when democracy was more limited, and the aristocracy richer and more influential. Presumably they want rule by an elite, but with some democratic restraints.
25. Social Practice / D. Justice / 2. The Law / c. Natural law
Stoics originated the concept of natural law, as agreed correct reasoning [Stoic school, by Annas]
     Full Idea: The Stoics are the originators of one of the most influential concepts in political philosophy, that of natural law. …It is simply correct moral reasoning, thought of as being prescriptive.
     From: report of Stoic school (fragments/reports [c.200 BCE]) by Julia Annas - The Morality of Happiness 13.3
25. Social Practice / F. Life Issues / 4. Suicide
Stoics say a wise man will commit suicide if he has a good enough reason [Stoic school, by Diog. Laertius]
     Full Idea: Stoics say that a wise man will very rationally take himself out of life, either for the sake of his country or of his friends, or if he suffers from bitter pain, mutilation or incurable disease.
     From: report of Stoic school (fragments/reports [c.200 BCE]) by Diogenes Laertius - Lives of Eminent Philosophers 07.1.66
Suicide is reasonable, for one's country or friends, or because of very bad health [Stoic school, by Diog. Laertius]
     Full Idea: The wise man will commit suicide, for a good reason, both on behalf of his fatherland and on behalf of his friends, and if he should be in very severe pain or is mutilated or has an incurable disease.
     From: report of Stoic school (fragments/reports [c.200 BCE]) by Diogenes Laertius - Lives of Eminent Philosophers 07.130
     A reaction: Being in a state of despair or depression doesn't seem to figure on the list. Suicide for friends, but not for family?
26. Natural Theory / A. Speculations on Nature / 1. Nature
Stoic 'nature' is deterministic, physical and teleological [Stoic school, by Annas]
     Full Idea: 'The nature of things' matters for the Stoics because they hold strong theses about the way things are: they are determinists, physicalists, teleologists.
     From: report of Stoic school (fragments/reports [c.200 BCE]) by Julia Annas - The Morality of Happiness Ch.5
26. Natural Theory / A. Speculations on Nature / 5. Infinite in Nature
Unlike Epicurus, Stoics distinguish the Whole from the All, with the latter including the void [Stoic school, by Sext.Empiricus]
     Full Idea: The Stoic school say that the Whole is the Cosmos, whereas the All is the external void together with the Cosmos, so the Whole is limited but the All is unlimited. (Epicurus gives the two names indifferently to both).
     From: report of Stoic school (fragments/reports [c.200 BCE]) by Sextus Empiricus - Against the Physicists (two books) I.332
     A reaction: Epicurus needed the void as part of the Cosmos, into which the atoms can move. Presumably the Stoic void is infinite, but how far does the Stoic Cosmos extend?
26. Natural Theory / D. Laws of Nature / 8. Scientific Essentialism / e. Anti scientific essentialism
The cosmos has two elements - passive matter, and active cause (or reason) which shapes it [Stoic school, by Seneca]
     Full Idea: Stoics say there are two elements in the cosmos, cause and matter. Matter lies inert and inactive, a substance of unlimited potential, but destined to remain idle if no one sets it in motion; it is cause (the same as reason) that fashions matter.
     From: report of Stoic school (fragments/reports [c.200 BCE]) by Seneca the Younger - Letters from a Stoic 065
     A reaction: [compressed] It take this to be anti-essentialist, because the point of a scientific essence is to be the source of the activities and structures of the matter. Seneca must think matter lacks essence, in order to be moulded like this. Note 'unlimited'.
27. Natural Reality / B. Modern Physics / 3. Chromodynamics / a. Chromodynamics
The strong force pulls, but also pushes apart if nucleons get too close together [Inwagen]
     Full Idea: The strong force doesn't always pull nucleons together, but pushes them apart if they get too close.
     From: Peter van Inwagen (Material Beings [1990], 07)
     A reaction: Philosophers tend to learn their physics from other philosophers. But that's because philosophers are brilliant at picking out the interesting parts of physics, and skipping the boring stuff.
27. Natural Reality / E. Cosmology / 2. Eternal Universe
The cosmos is regularly consumed and reorganised by the primary fire [Stoic school, by Aristocles]
     Full Idea: At certain fated times the entire cosmos goes up in flames and then is organised again. And the primary fire is like a kind of seed, containing the rational principles and cause of all things and events, past, present and future.
     From: report of Stoic school (fragments/reports [c.200 BCE]) by Aristocles - works
     A reaction: [in Eusebius] I wonder why the stoics thought this? Is it just spring cleaning? So is each cycle different? Does that mean that the primary fire was different at each seminal event? What made it different? Or is it eternal recurrence?
27. Natural Reality / F. Chemistry / 2. Modern Elements
Is one atom a piece of gold, or is a sizable group of atoms required? [Inwagen]
     Full Idea: A physicist once told me that of course a gold atom was a piece of gold, and a physical chemist has assured me that the smallest possible piece of gold would have to be composed of sixteen or seventeen atoms.
     From: Peter van Inwagen (Material Beings [1990], 01)
     A reaction: The issue is at what point all the properties that we normally begin to associate with gold begin to appear. One water molecule can hardly have a degree of viscosity or liquidity.
27. Natural Reality / G. Biology / 2. Life
At the lower level, life trails off into mere molecular interaction [Inwagen]
     Full Idea: The lives of the lower links of the Great Chain of Being trail off into vague, temporary episodes of molecular interaction.
     From: Peter van Inwagen (Material Beings [1990], 18)
     A reaction: His case involves conceding all sorts of vagueness to life, but asserting the utter distinctness of the full blown cases of more elaborate life. I don't really concede the distinction.
Some events are only borderline cases of lives [Inwagen]
     Full Idea: There are events of which it is neither definitely true nor definitely false that those events are lives. I do not see how we can deny this.
     From: Peter van Inwagen (Material Beings [1990], 18)
     A reaction: Very frustrating, since this is my main objection to Van Inwagen's distinction between unified lives and mere collections of simples. Some boundaries are real enough, despite their vagueness, and others indicate that there is no real distinction.
Unlike waves, lives are 'jealous'; it is almost impossible for them to overlap [Inwagen]
     Full Idea: A wave is not a 'jealous' event. Lives, however, are jealous. It cannot be that the activities of the Xs constitute at one and the same time two lives. Only in certain special cases can two lives overlap.
     From: Peter van Inwagen (Material Beings [1990], 09)
One's mental and other life is centred on the brain, unlike any other part of the body [Inwagen]
     Full Idea: One's life - not simply one's mental life - is centered in the activity of the simples that virtually compose one's brain in a way in which it is not centered in the activity of any of the other simples that compose one.
     From: Peter van Inwagen (Material Beings [1990], 15)
     A reaction: This justifies the common view that 'one follows one's brain'. I take that to mean that my brain embodies my essence. I would read 'centered on' as 'explains'.
A tumour may spread a sort of life, but it is not a life, or an organism [Inwagen]
     Full Idea: A tumour is not an organism (or a parasite) and there is no self-regulating event that is its life. It does not fill one space, but is a locus within which a certain sort of thing is happening: the spreading of a certain sort of (mass-term) life.
     From: Peter van Inwagen (Material Beings [1990], 09)
Being part of an organism's life is a matter of degree, and vague [Inwagen]
     Full Idea: Being caught up in the life of an organism is, like being rich or being tall, a matter of degree, and is in that sense a vague condition.
     From: Peter van Inwagen (Material Beings [1990], 17)
     A reaction: Van Inwagen is trying to cover himself, given that he makes a sharp distinction between living organisms, which are unified objects, and everything else, which isn't. There may be a vague centre to a 'life', as well as vague boundaries.
The chemical reactions in a human life involve about sixteen elements [Inwagen]
     Full Idea: There are sixteen or so chemical elements involved in those chemical reactions that collectively constitute the life of a human being.
     From: Peter van Inwagen (Material Beings [1990], 09)
Life is vague at both ends, but could it be totally vague? [Inwagen]
     Full Idea: Individual human lives are infected with vagueness at both ends. ...But could there be a 'borderline life'?
     From: Peter van Inwagen (Material Beings [1990], 18)
     A reaction: Van Inwagen says (p.239) that there may be wholly vague lives, though it would suit his case better if there were not.
A flame is like a life, but not nearly so well individuated [Inwagen]
     Full Idea: A flame, though it is a self-maintaining event, does not seem to be nearly so well individuated as a life.
     From: Peter van Inwagen (Material Beings [1990], 09)
     A reaction: This is to counter the standard problem that if you attempt to define 'life', fire turns out to tick nearly all the same boxes. The concept of 'individuated' often strikes me as unsatisfactory. How does a bonfire fail to be individuated?
If God were to 'reassemble' my atoms of ten years ago, the result would certainly not be me [Inwagen]
     Full Idea: If God were to 'reassemble' the atoms that composed me ten years ago, the resulting organism would certainly not be me.
     From: Peter van Inwagen (Material Beings [1990], 13)
     A reaction: What is obvious to Van Inwagen is not obvious to me. He thinks lives are special. Such examples just leave us bewildered about what counts as 'the same', because our concept of sameness wasn't designed to deal with such cases.
28. God / A. Divine Nature / 2. Divine Nature
Early Stoics called the logos 'god', meaning not a being, but the principle of the universe [Stoic school]
     Full Idea: Logos was also called 'god' or 'Zeus' by the early Stoics, but they did not think of this deity as a separate being, but as a principle of organization of things. As the soul is the principle of an individual life, so 'god' is the soul of the universe.
     From: Stoic school (fragments/reports [c.200 BCE]), quoted by A.C. Grayling - What is Good? Ch.3
     A reaction: This sounds not too far from Spinoza's pantheism. Interestingly, the Stoics were making God more impersonal, and it is Jesus who reverts to the much more popularly appealing personal image.
28. God / B. Proving God / 2. Proofs of Reason / b. Ontological Proof critique
There is no reason to think that mere existence is a valuable thing [Inwagen]
     Full Idea: There is no reason to suppose - whatever Saint Anselm and Descartes may have thought - that mere existence is a valuable thing.
     From: Peter van Inwagen (Material Beings [1990], 12)
     A reaction: This is one of the simplest and most powerful objections to the Ontological Argument. God's existence may be of great value, but the existence of Hitler wasn't.
28. God / C. Attitudes to God / 2. Pantheism
Stoics say god is matter, or an inseparable quality of it, or is the power within it [Stoic school, by Chalcidius]
     Full Idea: The Stoics say that god is that which matter is or that god is the inseparable quality of matter and that he moves through matter just as semen moves through the genital organs.
     From: report of Stoic school (fragments/reports [c.200 BCE]) by Chalcidius - Commentary on Plato's 'Timaeus' 294
     A reaction: This actually offers three different theories - of identity, of supervenience, and of omnipresence. It certainly seems close to pantheism. Such theories invite Ockham's Razor, which would shift talk to 'nature', and leave out 'god'.
29. Religion / D. Religious Issues / 2. Immortality / a. Immortality
Virtuous souls endure till the end, foolish souls for a short time, animal souls not at all [Stoic school, by Eusebius]
