| 7911 | Theory vanishes when one has obtained wisdom [Rahulabhadra] |
| 16281 | Honesty requires philosophical theories we can commit to with our ordinary commonsense [Lewis] |
| 21461 | I tried to be unsystematic and piecemeal, but failed; my papers presuppose my other views [Lewis] |
| 16288 | Analysis reduces primitives and makes understanding explicit (without adding new knowledge) [Lewis] |
| 15545 | Armstrong's analysis seeks truthmakers rather than definitions [Lewis] |
| 8605 | In addition to analysis of a concept, one can deny it, or accept it as primitive [Lewis] |

| 15457 | Interdefinition is useless by itself, but if we grasp one separately, we have them both [Lewis] |
| 15527 | Defining terms either enables elimination, or shows that they don't require elimination [Lewis] |
| 3993 | Arguments are nearly always open to challenge, but they help to explain a position rather than force people to believe [Lewis] |
| 10845 | To be true a sentence must express a proposition, and not be ambiguous or vague or just expressive [Lewis] |
| 9651 | Verisimilitude might be explained as being close to the possible world where the truth is exact [Lewis] |
| 15557 | Verisimilitude has proved hard to analyse, and seems to have several components [Lewis] |
| 10847 | Truthmakers are about existential grounding, not about truth [Lewis] |
| 15546 | Predications aren't true because of what exists, but of how it exists [Lewis] |
| 15548 | Say 'truth is supervenient on being', but construe 'being' broadly [Lewis] |
| 15549 | If it were true that nothing at all existed, would that have a truthmaker? [Lewis] |
| 14399 | Presentism says only the present exists, so there is nothing for tensed truths to supervene on [Lewis] |
| 10846 | Truthmaker is correspondence, but without the requirement to be one-to-one [Lewis] |
| 16456 | For modality Lewis rejected boxes and diamonds, preferring worlds, and an index for the actual one [Lewis, by Stalnaker] |
| 18395 | Sets are mereological sums of the singletons of their members [Lewis, by Armstrong] |
| 10807 | Mathematics reduces to set theory, which reduces, with some mereology, to the singleton function [Lewis] |
| 15496 | We can build set theory on singletons: classes are then fusions of subclasses, membership is the singleton [Lewis] |
| 15500 | Classes divide into subclasses in many ways, but into members in only one way [Lewis] |
| 15499 | A subclass of a subclass is itself a subclass; a member of a member is not in general a member [Lewis] |
| 10811 | The null set plays the role of last resort, for class abstracts and for existence [Lewis] |
| 15503 | We needn't accept this speck of nothingness, this black hole in the fabric of Reality! [Lewis] |
| 15498 | We can accept the null set, but there is no null class of anything [Lewis] |
| 15502 | There are four main reasons for asserting that there is an empty set [Lewis] |
| 10809 | We can accept the null set, but not a null class, a class lacking members [Lewis] |
| 10812 | The null set is not a little speck of sheer nothingness, a black hole in Reality [Lewis] |
| 15497 | We can replace the membership relation with the member-singleton relation (plus mereology) [Lewis] |
| 15506 | If we don't understand the singleton, then we don't understand classes [Lewis] |
| 15511 | If singleton membership is external, why is an object a member of one rather than another? [Lewis] |
| 15513 | Maybe singletons have a structure, of a thing and a lasso? [Lewis] |
| 10813 | What on earth is the relationship between a singleton and an element? [Lewis] |
| 10814 | Are all singletons exact intrinsic duplicates? [Lewis] |
| 15507 | Set theory has some unofficial axioms, generalisations about how to understand it [Lewis] |
| 10191 | Set theory reduces to a mereological theory with singletons as the only atoms [Lewis, by MacBride] |
| 15523 | Set theory isn't innocent; it generates infinities from a single thing; but mathematics needs it [Lewis] |
| 15508 | If singletons are where their members are, then so are all sets [Lewis] |
| 15514 | A huge part of Reality is only accepted as existing if you have accepted set theory [Lewis] |
| 10806 | Megethology is the result of adding plural quantification to mereology [Lewis] |
| 10816 | We can use mereology to simulate quantification over relations [Lewis] |
| 15533 | We can quantify over fictions by quantifying for real over their names [Lewis] |
| 15731 | Quantification sometimes commits to 'sets', but sometimes just to pluralities (or 'classes') [Lewis] |
| 15525 | Plural quantification lacks a complete axiom system [Lewis] |
| 15518 | I like plural quantification, but am not convinced of its connection with second-order logic [Lewis] |
| 15534 | We could quantify over impossible objects - as bundles of properties [Lewis] |
| 14212 | A consistent theory just needs one model; isomorphic versions will do too, and large domains provide those [Lewis] |

| 10808 | Mathematics is generalisations about singleton functions [Lewis] |
| 15524 | Zermelo's model of arithmetic is distinctive because it rests on a primitive of set theory [Lewis] |
| 15517 | Giving up classes means giving up successful mathematics because of dubious philosophy [Lewis] |
| 15515 | To be a structuralist, you quantify over relations [Lewis] |
| 10815 | We don't need 'abstract structures' to have structural truths about successor functions [Lewis] |
| 15532 | 'Allists' embrace the existence of all controversial entities; 'noneists' reject all but the obvious ones [Lewis] |
| 15535 | We can't accept a use of 'existence' that says only some of the things there are actually exist [Lewis] |
| 15789 | Lewis's distinction of 'existing' from 'being actual' is Meinong's between 'existing' and 'subsisting' [Lycan on Lewis] |
| 10470 | There are only two kinds: sets, and possibilia (actual and possible particulars) [Lewis, by Oliver] |
| 15520 | Existence doesn't come in degrees; once asserted, it can't then be qualified [Lewis] |
| 20901 | True Being only occurs when it is completely full, with atoms and no void [Democritus, by Aristotle] |
| 14401 | Every proposition is entirely about being [Lewis] |
| 20902 | Being does not exist more than non-being [Democritus, by Aristotle] |
| 20904 | The non-existent exists as much as the existent, because it has causal powers [Democritus] |
| 20903 | The only distinctions are Configuration (shape), Disposition (order) and Turning (position) [Democritus, by Aristotle] |
| 20893 | Nothing comes from non-existence, or passes into it [Democritus, by Diog. Laertius] |
| 15540 | You can't deny temporary intrinsic properties by saying the properties are relations (to times) [Lewis] |
| 15561 | The events that suit semantics may not be the events that suit causation [Lewis] |
| 15566 | Events are classes, and so there is a mereology of their parts [Lewis] |
| 15567 | Some events involve no change; they must, because causal histories involve unchanges [Lewis] |
| 15565 | Events have inbuilt essences, as necessary conditions for their occurrence [Lewis] |
| 15564 | An event is a property of a unique space-time region [Lewis] |
| 8607 | Supervenience is reduction without existence denials, ontological priorities, or translatability [Lewis] |
| 3990 | The whole truth supervenes on the physical truth [Lewis] |
| 9650 | Supervenience concerns whether things could differ, so it is a modal notion [Lewis] |
| 3991 | Where pixels make up a picture, supervenience is reduction [Lewis] |
| 8606 | A supervenience thesis is a denial of independent variation [Lewis] |
| 16210 | Humean supervenience says the world is just a vast mosaic of qualities in space-time [Lewis] |
| 15501 | We have no idea of a third sort of thing, that isn't an individual, a class, or their mixture [Lewis] |
| 15504 | Atomless gunk is an individual whose parts all have further proper parts [Lewis] |
| 14213 | Anti-realists see the world as imaginary, or lacking joints, or beyond reference, or beyond truth [Lewis] |
| 8580 | Materialism is (roughly) that two worlds cannot differ without differing physically [Lewis] |
| 8909 | Abstractions may well be verbal fictions, in which we ignore some features of an object [Lewis] |
| 15543 | How do things combine to make states of affairs? Constituents can repeat, and fail to combine [Lewis] |
| 16458 | Semantic vagueness involves alternative and equal precisifications of the language [Lewis] |
| 9057 | Vagueness is semantic indecision: we haven't settled quite what our words are meant to express [Lewis] |
| 9671 | Whether or not France is hexagonal depends on your standards of precision [Lewis] |
| 15538 | Semantic indecision explains vagueness (if we have precisifications to be undecided about) [Lewis] |
| 20896 | It is not possible to know what sort each thing is [Democritus] |
| 15751 | Surely 'slept in by Washington' is a property of some bed? [Lewis] |
| 8571 | Universals are wholly present in their instances, whereas properties are spread around [Lewis] |
| 15735 | Properties don't have degree; they are determinate, and things have varying relations to them [Lewis] |
| 9656 | The 'abundant' properties are just any bizarre property you fancy [Lewis] |
| 15737 | To be a 'property' is to suit a theoretical role [Lewis] |
| 14979 | Being alone doesn't guarantee intrinsic properties; 'being alone' is itself extrinsic [Lewis, by Sider] |
| 15454 | Extrinsic properties come in degrees, with 'brother' less extrinsic than 'sibling' [Lewis] |
| 15742 | A disjunctive property can be unnatural, but intrinsic if its disjuncts are intrinsic [Lewis] |
| 15397 | If a global intrinsic never varies between possible duplicates, all necessary properties are intrinsic [Cameron on Lewis] |
| 15398 | Global intrinsic may make necessarily coextensive properties both intrinsic or both extrinsic [Cameron on Lewis] |
| 15435 | If you think universals are immanent, you must believe them to be sparse, and not every related predicate [Lewis] |
| 15400 | We must avoid circularity between what is intrinsic and what is natural [Lewis, by Cameron] |
| 15458 | A property is 'intrinsic' iff it can never differ between duplicates [Lewis] |
| 15459 | Ellipsoidal stars seem to have an intrinsic property which depends on other objects [Lewis] |
| 15741 | All of the natural properties are included among the intrinsic properties [Lewis] |
| 15752 | We might try defining the natural properties by a short list of them [Lewis] |
| 10717 | Natural properties figure in the analysis of similarity in intrinsic respects [Lewis, by Oliver] |
| 16217 | Lewisian natural properties fix reference of predicates, through a principle of charity [Lewis, by Hawley] |
| 8585 | Reference partly concerns thought and language, partly eligibility of referent by natural properties [Lewis] |
| 8613 | Objects are demarcated by density and chemistry, and natural properties belong in what is well demarcated [Lewis] |
| 8586 | Natural properties tend to belong to well-demarcated things, typically loci of causal chains [Lewis] |
| 8589 | For us, a property being natural is just an aspect of its featuring in the contents of our attitudes [Lewis] |
| 15460 | All perfectly natural properties are intrinsic [Lewis, by Lewis] |
| 15726 | Natural properties fix resemblance and powers, and are picked out by universals [Lewis] |
| 14996 | Natural properties give similarity, joint carving, intrinsicness, specificity, homogeneity... [Lewis] |
| 15743 | Defining natural properties by means of laws of nature is potentially circular [Lewis] |
| 15744 | We can't define natural properties by resemblance, if they are used to explain resemblance [Lewis] |
| 15740 | I don't take 'natural' properties to be fixed by the nature of one possible world [Lewis] |
| 16262 | Sparse properties rest either on universals, or on tropes, or on primitive naturalness [Lewis, by Maudlin] |
| 15451 | I assume there could be natural properties that are not instantiated in our world [Lewis] |
| 7031 | Lewis says properties are sets of actual and possible objects [Lewis, by Heil] |
| 8572 | Any class of things is a property, no matter how whimsical or irrelevant [Lewis] |
| 15464 | The distinction between dispositional and 'categorical' properties leads to confusion [Lewis] |
| 18433 | There are far more properties than any brain could ever encodify [Lewis] |
| 8604 | We need properties as semantic values for linguistic expressions [Lewis] |
| 15739 | There is the property of belonging to a set, so abundant properties are as numerous as the sets [Lewis] |
| 15563 | Properties are very abundant (unlike universals), and are used for semantics and higher-order variables [Lewis] |
| 10723 | A property is the set of its actual and possible instances [Lewis, by Oliver] |
| 9653 | It would be easiest to take a property as the set of its instances [Lewis] |
| 14499 | Properties are classes of possible and actual concrete particulars [Lewis, by Koslicki] |
| 4038 | Properties are sets of their possible instances (which separates 'renate' from 'cordate') [Lewis, by Mellor/Oliver] |
| 15399 | The property of being F is identical with the set of objects, in all possible worlds, which are F [Lewis, by Cameron] |
| 15733 | Accidentally coextensive properties come apart when we include their possible instances [Lewis] |
| 15732 | Properties don't seem to be sets, because different properties can have the same set [Lewis] |
| 15734 | If a property is relative, such as being a father or son, then set membership seems relative too [Lewis] |
| 15516 | A property is any class of possibilia [Lewis] |
| 9655 | Trilateral and triangular seem to be coextensive sets in all possible worlds [Lewis] |
| 16290 | I believe in properties, which are sets of possible individuals [Lewis] |
| 9657 | You must accept primitive similarity to like tropes, but tropes give a good account of it [Lewis] |
| 15433 | Tropes are particular properties, which cannot recur, but can be exact duplicates [Lewis] |
| 15748 | Trope theory needs a primitive notion for what unites some tropes [Lewis] |
| 15749 | Trope theory (unlike universals) needs a primitive notion of being duplicates [Lewis] |
| 15750 | Tropes need a similarity primitive, so they cannot be used to explain similarity [Lewis] |
| 9476 | If dispositions are more fundamental than causes, then they won't conceptually reduce to them [Bird on Lewis] |
| 15463 | All dispositions must have causal bases [Lewis] |
| 15120 | Lewisian properties have powers because of their relationships to other properties [Lewis, by Hawthorne] |
| 15554 | A disposition needs a causal basis, a property in a certain causal role. Could the disposition be the property? [Lewis] |
| 15461 | A 'finkish' disposition is real, but disappears when the stimulus occurs [Lewis] |
| 8573 | Most properties are causally irrelevant, and we can't spot the relevant ones. [Lewis] |
| 15453 | The main rivals to universals are resemblance or natural-class nominalism, or sparse trope theory [Lewis] |
| 8569 | I suspend judgements about universals, but their work must be done [Lewis] |
| 15745 | Universals recur, are multiply located, wholly present, make things overlap, and are held in common [Lewis] |
| 15746 | If particles were just made of universals, similar particles would be the same particle [Lewis] |
| 21961 | Physics aims to discover which universals actually exist [Lewis, by Moore,AW] |
| 15436 | Universals are meant to give an account of resemblance [Lewis] |
| 15747 | Universals aren't parts of things, because that relationship is transitive, and universals need not be [Lewis] |
| 8576 | The One over Many problem (in predication terms) deserves to be neglected (by ostriches) [Lewis] |
| 15438 | We can add a primitive natural/unnatural distinction to class nominalism [Lewis] |
| 8570 | To have a property is to be a member of a class, usually a class of things [Lewis] |
| 8574 | Class Nominalism and Resemblance Nominalism are pretty much the same [Lewis] |
| 15455 | Total intrinsic properties give us what a thing is [Lewis] |
| 3357 | Democritus denies reality to large objects, because atomic entities can't combine to produce new ones [Benardete,JA on Democritus] |
| 598 | Democritus said that substances could never be mixed, so atoms are the substances [Democritus, by Aristotle] |
| 15537 | If cats are vague, we deny that the many cats are one, or deny that the one cat is many [Lewis] |
| 15536 | We have one cloud, but many possible boundaries and aggregates for it [Lewis] |
| 15452 | We could not uphold a truthmaker for 'Fa' without structures [Lewis] |
| 15448 | The 'magical' view of structural universals says they are atoms, even though they have parts [Lewis] |
| 15449 | If 'methane' is an atomic structural universal, it has nothing to connect it to its carbon universals [Lewis] |
| 15439 | The 'pictorial' view of structural universals says they are wholes made of universals as parts [Lewis] |
| 15441 | The structural universal 'methane' needs the universal 'hydrogen' four times over [Lewis] |
| 15445 | Butane and Isobutane have the same atoms, but different structures [Lewis] |
| 15434 | Structural universals have a necessary connection to the universals forming its parts [Lewis] |
| 15437 | We can't get rid of structural universals if there are no simple universals [Lewis] |
| 15446 | Composition is not just making new things from old; there are too many counterexamples [Lewis] |
| 14748 | The many are many and the one is one, so they can't be identical [Lewis] |
| 6129 | Lewis affirms 'composition as identity' - that an object is no more than its parts [Lewis, by Merricks] |
| 15512 | In mereology no two things consist of the same atoms [Lewis] |
| 14210 | A gerrymandered mereological sum can be a mess, but still have natural joints [Lewis] |
| 15519 | Trout-turkeys exist, despite lacking cohesion, natural joints and united causal power [Lewis] |
| 15521 | Given cats, a fusion of cats adds nothing further to reality [Lewis] |
| 15522 | The one has different truths from the many; it is one rather than many, one rather than six [Lewis] |
| 10566 | Lewis prefers giving up singletons to giving up sums [Lewis, by Fine,K] |
| 9667 | Mereological composition is unrestricted: any class of things has a mereological sum [Lewis] |
| 13268 | There are no restrictions on composition, because they would be vague, and composition can't be vague [Lewis, by Sider] |
| 15440 | A whole is distinct from its parts, but is not a further addition in ontology [Lewis] |
| 15444 | Different things (a toy house and toy car) can be made of the same parts at different times [Lewis] |
| 14244 | Lewis only uses fusions to create unities, but fusions notoriously flatten our distinctions [Oliver/Smiley on Lewis] |
| 10660 | A commitment to cat-fusions is not a further commitment; it is them and they are it [Lewis] |
| 10810 | I say that absolutely any things can have a mereological fusion [Lewis] |
| 11976 | Aristotelian essentialism says essences are not relative to specification [Lewis] |
| 13793 | An essential property is one possessed by all counterparts [Lewis, by Elder] |
| 9663 | A thing 'perdures' if it has separate temporal parts, and 'endures' if it is wholly present at different times [Lewis] |
| 14737 | Properties cannot be relations to times, if there are temporary properties which are intrinsic [Lewis, by Sider] |
| 9664 | Endurance is the wrong account, because things change intrinsic properties like shape [Lewis] |
| 9665 | There are three responses to the problem that intrinsic shapes do not endure [Lewis] |
| 19280 | I can ask questions which create a context in which origin ceases to be essential [Lewis] |
| 15968 | Identity is simple - absolutely everything is self-identical, and nothing is identical to another thing [Lewis] |
| 15969 | Two things can never be identical, so there is no problem [Lewis] |
| 16079 | De re modal predicates are ambiguous [Lewis, by Rudder Baker] |
| 11978 | Causal necessities hold in all worlds compatible with the laws of nature [Lewis] |
| 15560 | We can explain a chance event, but can never show why some other outcome did not occur [Lewis] |
| 14283 | A conditional probability does not measure the probability of the truth of any proposition [Lewis, by Edgington] |
| 14361 | Lewis says indicative conditionals are truth-functional [Lewis, by Jackson] |
| 8434 | In good counterfactuals the consequent holds in world like ours except that the antecedent is true [Lewis, by Horwich] |
| 8425 | For true counterfactuals, both antecedent and consequent true is closest to actuality [Lewis] |
| 15462 | Backtracking counterfactuals go from supposed events to their required causal antecedents [Lewis] |
| 9660 | The impossible can be imagined as long as it is a bit vague [Lewis] |
| 9669 | There are no free-floating possibilia; they have mates in a world, giving them extrinsic properties [Lewis] |
| 16132 | On mountains or in worlds, reporting contradictions is contradictory, so no such truths can be reported [Lewis] |
| 16133 | Possible worlds can contain contradictions if such worlds are seen as fictions [Lewis] |
| 12255 | For Lewis there is no real possibility, since all possibilities are actual [Oderberg on Lewis] |
| 9219 | Lewis posits possible worlds just as Quine says that physics needs numbers and sets [Lewis, by Sider] |
| 16283 | For me, all worlds are equal, with each being actual relative to itself [Lewis] |
| 15022 | If possible worlds really exist, then they are part of actuality [Sider on Lewis] |
| 10469 | A world is a maximal mereological sum of spatiotemporally interrelated things [Lewis] |
| 18415 | The actual world is just the world you are in [Lewis, by Cappelen/Dever] |
| 15790 | Lewis can't know possible worlds without first knowing what is possible or impossible [Lycan on Lewis] |
| 15791 | What are the ontological grounds for grouping possibilia into worlds? [Lycan on Lewis] |
| 16441 | Lewis rejects actualism because he identifies properties with sets [Lewis, by Stalnaker] |
| 16282 | Ersatzers say we have one world, and abstract representations of how it might have been [Lewis] |
| 16284 | Ersatz worlds represent either through language, or by models, or magically [Lewis] |
| 16286 | Linguistic possible worlds need a complete supply of unique names for each thing [Lewis] |
| 16287 | Maximal consistency for a world seems a modal distinction, concerning what could be true together [Lewis] |
| 9662 | Linguistic possible worlds have problems of inconsistencies, no indiscernibles, and vocabulary [Lewis] |
| 7690 | If sets exist, then defining worlds as proposition sets implies an odd distinction between existing and actual [Jacquette on Lewis] |
| 11979 | It doesn't take the whole of a possible Humphrey to win the election [Lewis] |
| 15530 | A logically determinate name names the same thing in every possible world [Lewis] |
| 14404 | The counterpart relation is sortal-relative, so objects need not be a certain way [Lewis, by Merricks] |
| 5441 | Why should statements about what my 'counterpart' could have done interest me? [Mautner on Lewis] |
| 5440 | A counterpart in a possible world is sufficiently similar, and more similar than anything else [Lewis, by Mautner] |
| 16291 | In counterpart theory 'Humphrey' doesn't name one being, but a mereological sum of many beings [Lewis] |
| 16994 | Counterpart theory is bizarre, as no one cares what happens to a mere counterpart [Kripke on Lewis] |
| 11974 | Counterparts are not the original thing, but resemble it more than other things do [Lewis] |
| 11975 | If the closest resembler to you is in fact quite unlike you, then you have no counterpart [Lewis] |
| 11977 | Essential attributes are those shared with all the counterparts [Lewis] |
| 11903 | Extreme haecceitists could say I might have been a poached egg, but it is too remote to consider [Lewis, by Mackie,P] |
| 15129 | Haecceitism implies de re differences but qualitative identity [Lewis] |
| 9670 | Extreme haecceitism says you might possibly be a poached egg [Lewis] |
| 16392 | A content is a property, and believing it is self-ascribing that property [Lewis, by Recanati] |
| 12899 | The timid student has knowledge without belief, lacking confidence in their correct answer [Lewis] |
| 12897 | To say S knows P, but cannot eliminate not-P, sounds like a contradiction [Lewis] |
| 1532 | Sensible qualities can't be real if they appear different to different creatures [Democritus, by Theophrastus] |
| 15509 | Some say qualities are parts of things - as repeatable universals, or as particulars [Lewis] |
| 20894 | Man is separated from reality [Democritus] |
| 517 | All evidence comes from senses, so they are indispensable to the mind [Democritus] |
| 20897 | Obscure knowledge belongs to the five senses, and genuine knowledge is the other type [Democritus] |
| 12898 | Justification is neither sufficient nor necessary for knowledge [Lewis] |
| 16279 | General causal theories of knowledge are refuted by mathematics [Lewis] |
| 12895 | Knowing is context-sensitive because the domain of quantification varies [Lewis, by Cohen,S] |
| 19562 | We have knowledge if alternatives are eliminated, but appropriate alternatives depend on context [Lewis, by Cohen,S] |
| 577 | Democritus says there is either no truth, or it is concealed from us [Democritus, by Aristotle] |
| 20895 | We actually know nothing, and opinions are mere flux [Democritus] |
| 1528 | We in fact know nothing, but we each restructure our reality with beliefs [Democritus] |
| 492 | It is obviously impossible to understand the reality of each thing [Democritus] |
| 515 | We know nothing in reality; for truth lies in an abyss [Democritus] |
| 15531 | The Ramsey sentence of a theory says that it has at least one realisation [Lewis] |
| 15528 | A Ramsey sentence just asserts that a theory can be realised, without saying by what [Lewis] |
| 15526 | There is a method for defining new scientific terms just using the terms we already understand [Lewis] |
| 15529 | It is better to have one realisation of a theory than many - but it may not always be possible [Lewis] |
| 9661 | Induction is just reasonable methods of inferring the unobserved from the observed [Lewis] |
| 9652 | To just expect unexamined emeralds to be grue would be totally unreasonable [Lewis] |
| 15559 | Does a good explanation produce understanding? That claim is just empty [Lewis] |
| 15556 | Science may well pursue generalised explanation, rather than laws [Lewis] |
| 15558 | A good explanation is supposed to show that the event had to happen [Lewis] |
| 20892 | Democritus was devoted to discovering causal explanations [Democritus, by Eusebius] |
| 9658 | An explanation tells us how an event was caused [Lewis] |
| 4809 | Lewis endorses the thesis that all explanation of singular events is causal explanation [Lewis, by Psillos] |
| 16280 | Often explanaton seeks fundamental laws, rather than causal histories [Lewis] |
| 14321 | To explain an event is to provide some information about its causal history [Lewis] |
| 16274 | If the well-ordering of a pack of cards was by shuffling, the explanation would make it more surprising [Lewis] |
| 3995 | A mind is an organ of representation [Lewis] |
| 5882 | Democritus says soul consists of smooth round bodies brought together in accidental collision [Democritus, by Cicero] |
| 6034 | Atomists say soul has a rational part in the chest, and a diffused non-rational part [Democritus, by Aetius] |
