327 ideas
12644 | Who cares what 'philosophy' is? Most pre-1950 thought doesn't now count as philosophy [Fodor] |
12633 | Definitions often give necessary but not sufficient conditions for an extension [Fodor] |
2474 | It seems likely that analysis of concepts is impossible, but justification can survive without it [Fodor] |
2481 | Despite all the efforts of philosophers, nothing can ever be reduced to anything [Fodor] |
2505 | Turing invented the idea of mechanical rationality (just based on syntax) [Fodor] |
2463 | A standard naturalist view is realist, externalist, and computationalist, and believes in rationality [Fodor] |
18137 | Impredicative definitions are wrong, because they change the set that is being defined? [Bostock] |
12619 | We have no successful definitions, because they all use indefinable words [Fodor] |
2470 | Transcendental arguments move from knowing Q to knowing P because it depends on Q [Fodor] |
2435 | Psychology has to include the idea that mental processes are typically truth-preserving [Fodor] |
13439 | Venn Diagrams map three predicates into eight compartments, then look for the conclusion [Bostock] |
13422 | 'Conjunctive Normal Form' is ensuring that no disjunction has a conjunction within its scope [Bostock] |
13421 | 'Disjunctive Normal Form' is ensuring that no conjunction has a disjunction within its scope [Bostock] |
13355 | 'Disjunction' says that Γ,φ∨ψ|= iff Γ,φ|= and Γ,ψ|= [Bostock] |
13356 | The 'conditional' is that Γ|=φ→ψ iff Γ,φ|=ψ [Bostock] |
13350 | 'Assumptions' says that a formula entails itself (φ|=φ) [Bostock] |
13351 | 'Thinning' allows that if premisses entail a conclusion, then adding further premisses makes no difference [Bostock] |
13352 | 'Cutting' allows that if x is proved, and adding y then proves z, you can go straight to z [Bostock] |
13353 | 'Negation' says that Γ,¬φ|= iff Γ|=φ [Bostock] |
13354 | 'Conjunction' says that Γ|=φ∧ψ iff Γ|=φ and Γ|=ψ [Bostock] |
13610 | A logic with ¬ and → needs three axiom-schemas and one rule as foundation [Bostock] |
18122 | Classical interdefinitions of logical constants and quantifiers is impossible in intuitionism [Bostock] |
18074 | Intuitionists rely on assertability instead of truth, but assertability relies on truth [Kitcher] |
13846 | A 'free' logic can have empty names, and a 'universally free' logic can have empty domains [Bostock] |
18114 | There is no single agreed structure for set theory [Bostock] |
18107 | A 'proper class' cannot be a member of anything [Bostock] |
18115 | We could add axioms to make sets either as small or as large as possible [Bostock] |
18139 | The Axiom of Choice relies on reference to sets that we are unable to describe [Bostock] |
18105 | Replacement enforces a 'limitation of size' test for the existence of sets [Bostock] |
2442 | Inferences are surely part of the causal structure of the world [Fodor] |
18108 | First-order logic is not decidable: there is no test of whether any formula is valid [Bostock] |
18109 | The completeness of first-order logic implies its compactness [Bostock] |
13545 | Elementary logic cannot distinguish clearly between the finite and the infinite [Bostock] |
13346 | Truth is the basic notion in classical logic [Bostock] |
13822 | Fictional characters wreck elementary logic, as they have contradictions and no excluded middle [Bostock] |
12430 | Classical logic is our preconditions for assessing empirical evidence [Kitcher] |
12431 | I believe classical logic because I was taught it and use it, but it could be undermined [Kitcher] |
13623 | The syntactic turnstile |- φ means 'there is a proof of φ' or 'φ is a theorem' [Bostock] |
13349 | Γ|=φ is 'entails'; Γ|= is 'is inconsistent'; |=φ is 'valid' [Bostock] |
13347 | Validity is a conclusion following for premises, even if there is no proof [Bostock] |
13348 | It seems more natural to express |= as 'therefore', rather than 'entails' [Bostock] |
13614 | MPP: 'If Γ|=φ and Γ|=φ→ψ then Γ|=ψ' (omit Γs for Detachment) [Bostock] |
13617 | MPP is a converse of Deduction: If Γ |- φ→ψ then Γ,φ|-ψ [Bostock] |
13799 | The sign '=' is a two-place predicate expressing that 'a is the same thing as b' (a=b) [Bostock] |
13800 | |= α=α and α=β |= φ(α/ξ ↔ φ(β/ξ) fix identity [Bostock] |
13803 | If we are to express that there at least two things, we need identity [Bostock] |
13357 | Truth-functors are usually held to be defined by their truth-tables [Bostock] |
12664 | A truth-table, not inferential role, defines 'and' [Fodor] |
13812 | A 'zero-place' function just has a single value, so it is a name [Bostock] |
13811 | A 'total' function ranges over the whole domain, a 'partial' function over appropriate inputs [Bostock] |
13360 | In logic, a name is just any expression which refers to a particular single object [Bostock] |
3005 | 'Jocasta' needs to be distinguished from 'Oedipus's mother' because they are connected by different properties [Fodor] |
12648 | Names in thought afford a primitive way to bring John before the mind [Fodor] |
12650 | 'Paderewski' has two names in mentalese, for his pianist file and his politician file [Fodor] |
13361 | An expression is only a name if it succeeds in referring to a real object [Bostock] |
13813 | Definite descriptions don't always pick out one thing, as in denials of existence, or errors [Bostock] |
13814 | Definite desciptions resemble names, but can't actually be names, if they don't always refer [Bostock] |
13816 | Because of scope problems, definite descriptions are best treated as quantifiers [Bostock] |
13817 | Definite descriptions are usually treated like names, and are just like them if they uniquely refer [Bostock] |
13848 | We are only obliged to treat definite descriptions as non-names if only the former have scope [Bostock] |
13815 | Names do not have scope problems (e.g. in placing negation), but Russell's account does have that problem [Bostock] |
13438 | 'Prenex normal form' is all quantifiers at the beginning, out of the scope of truth-functors [Bostock] |
13818 | If we allow empty domains, we must allow empty names [Bostock] |
18123 | Substitutional quantification is just standard if all objects in the domain have a name [Bostock] |
13801 | An 'informal proof' is in no particular system, and uses obvious steps and some ordinary English [Bostock] |
13619 | Quantification adds two axiom-schemas and a new rule [Bostock] |
13622 | Axiom systems from Frege, Russell, Church, Lukasiewicz, Tarski, Nicod, Kleene, Quine... [Bostock] |
13615 | 'Conditonalised' inferences point to the Deduction Theorem: If Γ,φ|-ψ then Γ|-φ→ψ [Bostock] |
13616 | The Deduction Theorem greatly simplifies the search for proof [Bostock] |
13620 | Proof by Assumptions can always be reduced to Proof by Axioms, using the Deduction Theorem [Bostock] |
13621 | The Deduction Theorem and Reductio can 'discharge' assumptions - they aren't needed for the new truth [Bostock] |
13753 | Natural deduction takes proof from assumptions (with its rules) as basic, and axioms play no part [Bostock] |
13755 | Excluded middle is an introduction rule for negation, and ex falso quodlibet will eliminate it [Bostock] |
13758 | In natural deduction we work from the premisses and the conclusion, hoping to meet in the middle [Bostock] |
13754 | Natural deduction rules for → are the Deduction Theorem (→I) and Modus Ponens (→E) [Bostock] |
18120 | The Deduction Theorem is what licenses a system of natural deduction [Bostock] |
13756 | A tree proof becomes too broad if its only rule is Modus Ponens [Bostock] |
13757 | Unlike natural deduction, semantic tableaux have recipes for proving things [Bostock] |
13762 | Tableau rules are all elimination rules, gradually shortening formulae [Bostock] |
13611 | Tableau proofs use reduction - seeking an impossible consequence from an assumption [Bostock] |
13612 | Non-branching rules add lines, and branching rules need a split; a branch with a contradiction is 'closed' [Bostock] |
13613 | A completed open branch gives an interpretation which verifies those formulae [Bostock] |
13761 | In a tableau proof no sequence is established until the final branch is closed; hypotheses are explored [Bostock] |
13759 | Each line of a sequent calculus is a conclusion of previous lines, each one explicitly recorded [Bostock] |
13760 | A sequent calculus is good for comparing proof systems [Bostock] |
13364 | Interpretation by assigning objects to names, or assigning them to variables first [Bostock, by PG] |
13821 | Extensionality is built into ordinary logic semantics; names have objects, predicates have sets of objects [Bostock] |
13362 | If an object has two names, truth is undisturbed if the names are swapped; this is Extensionality [Bostock] |
13541 | For 'negation-consistent', there is never |-(S)φ and |-(S)¬φ [Bostock] |
13540 | A set of formulae is 'inconsistent' when there is no interpretation which can make them all true [Bostock] |
13542 | A proof-system is 'absolutely consistent' iff we don't have |-(S)φ for every formula [Bostock] |
12656 | P-and-Q gets its truth from the truth of P and truth of Q, but consistency isn't like that [Fodor] |
13544 | Inconsistency or entailment just from functors and quantifiers is finitely based, if compact [Bostock] |
13618 | Compactness means an infinity of sequents on the left will add nothing new [Bostock] |
18125 | Berry's Paradox considers the meaning of 'The least number not named by this name' [Bostock] |
6298 | Kitcher says maths is an idealisation of the world, and our operations in dealing with it [Kitcher, by Resnik] |
12392 | Mathematical a priorism is conceptualist, constructivist or realist [Kitcher] |
18078 | The interest or beauty of mathematics is when it uses current knowledge to advance undestanding [Kitcher] |
12426 | The 'beauty' or 'interest' of mathematics is just explanatory power [Kitcher] |
18101 | Each addition changes the ordinality but not the cardinality, prior to aleph-1 [Bostock] |
18100 | ω + 1 is a new ordinal, but its cardinality is unchanged [Bostock] |
18102 | A cardinal is the earliest ordinal that has that number of predecessors [Bostock] |
18106 | Aleph-1 is the first ordinal that exceeds aleph-0 [Bostock] |
18095 | Instead of by cuts or series convergence, real numbers could be defined by axioms [Bostock] |
18099 | The number of reals is the number of subsets of the natural numbers [Bostock] |
12395 | Real numbers stand to measurement as natural numbers stand to counting [Kitcher] |
18093 | For Eudoxus cuts in rationals are unique, but not every cut makes a real number [Bostock] |
12425 | Complex numbers were only accepted when a geometrical model for them was found [Kitcher] |
18071 | A one-operation is the segregation of a single object [Kitcher] |
18066 | The old view is that mathematics is useful in the world because it describes the world [Kitcher] |
18110 | Infinitesimals are not actually contradictory, because they can be non-standard real numbers [Bostock] |
18083 | With infinitesimals, you divide by the time, then set the time to zero [Kitcher] |
18156 | Modern axioms of geometry do not need the real numbers [Bostock] |
18097 | The Peano Axioms describe a unique structure [Bostock] |
13358 | Ordinary or mathematical induction assumes for the first, then always for the next, and hence for all [Bostock] |
13359 | Complete induction assumes for all numbers less than n, then also for n, and hence for all numbers [Bostock] |
18148 | Hume's Principle is a definition with existential claims, and won't explain numbers [Bostock] |
18145 | Many things will satisfy Hume's Principle, so there are many interpretations of it [Bostock] |
18149 | There are many criteria for the identity of numbers [Bostock] |
18143 | Frege makes numbers sets to solve the Caesar problem, but maybe Caesar is a set! [Bostock] |
18116 | Numbers can't be positions, if nothing decides what position a given number has [Bostock] |
18117 | Structuralism falsely assumes relations to other numbers are numbers' only properties [Bostock] |
12393 | Intuition is no basis for securing a priori knowledge, because it is fallible [Kitcher] |
12420 | If mathematics comes through intuition, that is either inexplicable, or too subjective [Kitcher] |
18061 | Mathematical intuition is not the type platonism needs [Kitcher] |
18157 | Nominalism as based on application of numbers is no good, because there are too many applications [Bostock] |
18141 | Nominalism about mathematics is either reductionist, or fictionalist [Bostock] |
12387 | Mathematical knowledge arises from basic perception [Kitcher] |
12412 | My constructivism is mathematics as an idealization of collecting and ordering objects [Kitcher] |
18065 | We derive limited mathematics from ordinary things, and erect powerful theories on their basis [Kitcher] |
18077 | The defenders of complex numbers had to show that they could be expressed in physical terms [Kitcher] |
18150 | Actual measurement could never require the precision of the real numbers [Bostock] |
18158 | Ordinals are mainly used adjectively, as in 'the first', 'the second'... [Bostock] |
18127 | Simple type theory has 'levels', but ramified type theory has 'orders' [Bostock] |
18147 | Neo-logicists meet the Caesar problem by saying Hume's Principle is unique to number [Bostock] |
18144 | Neo-logicists agree that HP introduces number, but also claim that it suffices for the job [Bostock] |
18111 | Treating numbers as objects doesn't seem like logic, since arithmetic fixes their totality [Bostock] |
18146 | If Hume's Principle is the whole story, that implies structuralism [Bostock] |
12423 | Analyticity avoids abstract entities, but can there be truth without reference? [Kitcher] |
18129 | Many crucial logicist definitions are in fact impredicative [Bostock] |
18159 | Higher cardinalities in sets are just fairy stories [Bostock] |
18155 | A fairy tale may give predictions, but only a true theory can give explanations [Bostock] |
18069 | Arithmetic is an idealizing theory [Kitcher] |
18068 | Arithmetic is made true by the world, but is also made true by our constructions [Kitcher] |
18070 | We develop a language for correlations, and use it to perform higher level operations [Kitcher] |
18072 | Constructivism is ontological (that it is the work of an agent) and epistemological (knowable a priori) [Kitcher] |
18140 | The best version of conceptualism is predicativism [Bostock] |
18138 | Conceptualism fails to grasp mathematical properties, infinity, and objective truth values [Bostock] |
18063 | Conceptualists say we know mathematics a priori by possessing mathematical concepts [Kitcher] |
18064 | If meaning makes mathematics true, you still need to say what the meanings refer to [Kitcher] |
18131 | If abstracta only exist if they are expressible, there can only be denumerably many of them [Bostock] |
18134 | Predicativism makes theories of huge cardinals impossible [Bostock] |
18135 | If mathematics rests on science, predicativism may be the best approach [Bostock] |
18136 | If we can only think of what we can describe, predicativism may be implied [Bostock] |
18133 | The usual definitions of identity and of natural numbers are impredicative [Bostock] |
18132 | The predicativity restriction makes a difference with the real numbers [Bostock] |
12620 | If 'exist' is ambiguous in 'chairs and numbers exist', that mirrors the difference between chairs and numbers [Fodor] |
13543 | A relation is not reflexive, just because it is transitive and symmetrical [Bostock] |
13802 | Relations can be one-many (at most one on the left) or many-one (at most one on the right) [Bostock] |
2469 | The world is full of messy small things producing stable large-scale properties (e.g. mountains) [Fodor] |
7014 | A particle and a coin heads-or-tails pick out to perfectly well-defined predicates and properties [Fodor] |
12613 | Empiricists use dispositions reductively, as 'possibility of sensation' or 'possibility of experimental result' [Fodor] |
2475 | Don't define something by a good instance of it; a good example is a special case of the ordinary example [Fodor] |
18067 | Abstract objects were a bad way of explaining the structure in mathematics [Kitcher] |
13847 | If non-existent things are self-identical, they are just one thing - so call it the 'null object' [Bostock] |
13820 | The idea that anything which can be proved is necessary has a problem with empty names [Bostock] |
12653 | There's statistical, logical, nomological, conceptual and metaphysical possibility [Fodor] |
12428 | Many necessities are inexpressible, and unknowable a priori [Kitcher] |
12429 | Knowing our own existence is a priori, but not necessary [Kitcher] |
12651 | Some beliefs are only inferred when needed, like 'Shakespeare had not telephone' [Fodor] |
2502 | How do you count beliefs? [Fodor] |
12628 | Knowing that must come before knowing how [Fodor] |
2501 | Berkeley seems to have mistakenly thought that chairs are the same as after-images [Fodor] |
12390 | A priori knowledge comes from available a priori warrants that produce truth [Kitcher] |
3008 | Evolution suggests that innate knowledge of human psychology would be beneficial [Fodor] |
3009 | Sticklebacks have an innate idea that red things are rivals [Fodor] |
2990 | Contrary to commonsense, most of what is in the mind seems to be unlearned [Fodor] |
12418 | In long mathematical proofs we can't remember the original a priori basis [Kitcher] |
12389 | Knowledge is a priori if the experience giving you the concepts thus gives you the knowledge [Kitcher] |
12416 | We have some self-knowledge a priori, such as knowledge of our own existence [Kitcher] |
2465 | Maybe explaining the mechanics of perception will explain the concepts involved [Fodor] |
2504 | Rationalism can be based on an evolved computational brain with innate structure [Fodor] |
3978 | Associations are held to connect Ideas together in the way the world is connected together [Fodor] |
12617 | Associationism can't explain how truth is preserved [Fodor] |
2493 | According to empiricists abstraction is the fundamental mental process [Fodor] |
12625 | Pragmatism is the worst idea ever [Fodor] |
2494 | Rationalists say there is more to a concept than the experience that prompts it [Fodor] |
12413 | A 'warrant' is a process which ensures that a true belief is knowledge [Kitcher] |
20473 | If experiential can defeat a belief, then its justification depends on the defeater's absence [Kitcher, by Casullo] |
2462 | Control of belief is possible if you know truth conditions and what causes beliefs [Fodor] |
2454 | We can deliberately cause ourselves to have true thoughts - hence the value of experiments [Fodor] |
2455 | Interrogation and experiment submit us to having beliefs caused [Fodor] |
2460 | Participation in an experiment requires agreement about what the outcome will mean [Fodor] |
2461 | An experiment is a deliberate version of what informal thinking does all the time [Fodor] |
2458 | Theories are links in the causal chain between the environment and our beliefs [Fodor] |
2508 | The function of a mind is obvious [Fodor] |
2503 | Empirical approaches see mind connections as mirrors/maps of reality [Fodor] |
12636 | Mental states have causal powers [Fodor] |
2994 | In CRTT thought may be represented, content must be [Fodor] |
2443 | I say psychology is intentional, semantics is informational, and thinking is computation [Fodor] |
2453 | We are probably the only creatures that can think about our own thoughts [Fodor] |
15473 | How does anything get outside itself? [Fodor, by Martin,CB] |
2485 | Do intentional states explain our behaviour? [Fodor] |
2981 | Is intentionality outwardly folk psychology, inwardly mentalese? [Lyons on Fodor] |
7326 | Intentionality doesn't go deep enough to appear on the physicists' ultimate list of things [Fodor] |
15494 | We can't use propositions to explain intentional attitudes, because they would need explaining [Fodor] |
3976 | Intentional science needs objects with semantic and causal properties, and which obey laws [Fodor] |
3980 | Intentional states and processes may be causal relations among mental symbols [Fodor] |
18075 | Idealisation trades off accuracy for simplicity, in varying degrees [Kitcher] |
12661 | The different types of resemblance don't resemble one another [Fodor] |
2506 | If I have a set of mental modules, someone had better be in charge of them! [Fodor] |
2445 | Semantics v syntax is the interaction problem all over again [Fodor] |
2446 | Cartesians consider interaction to be a miracle [Fodor] |
2599 | Either intentionality causes things, or epiphenomenalism is true [Fodor] |
3001 | Behaviourism has no theory of mental causation [Fodor] |
2467 | Functionalists see pains as properties involving relations and causation [Fodor] |
2993 | Any piece of software can always be hard-wired [Fodor] |
12632 | In the Representational view, concepts play the key linking role [Fodor] |
3011 | Causal powers must be a crucial feature of mental states [Fodor] |
5498 | Mind is a set of hierarchical 'homunculi', which are made up in turn from subcomponents [Fodor, by Lycan] |
2597 | Contrary to the 'anomalous monist' view, there may well be intentional causal laws [Fodor] |
2489 | Why bother with neurons? You don't explain bird flight by examining feathers [Fodor] |
2985 | Are beliefs brains states, but picked out at a "higher level"? [Lyons on Fodor] |
2995 | Supervenience gives good support for mental causation [Fodor] |
2464 | Type physicalism equates mental kinds with physical kinds [Fodor] |
2468 | Type physicalism is a stronger claim than token physicalism [Fodor] |
2447 | Hume has no theory of the co-ordination of the mind [Fodor] |
2490 | Modern connectionism is just Hume's theory of the 'association' of 'ideas' [Fodor] |
12624 | Only the labels of nodes have semantic content in connectionism, and they play no role [Fodor] |
2991 | Hume's associationism offers no explanation at all of rational thought [Fodor] |
3002 | If mind is just physical, how can it follow the rules required for intelligent thought? [Fodor] |
2598 | Lots of physical properties are multiply realisable, so why shouldn't beliefs be? [Fodor] |
3981 | Most psychological properties seem to be multiply realisable [Fodor] |
12641 | Connectionism gives no account of how constituents make complex concepts [Fodor] |
2992 | We may be able to explain rationality mechanically [Fodor] |
2476 | The goal of thought is to understand the world, not instantly sort it into conceptual categories [Fodor] |
12640 | Associative thinking avoids syntax, but can't preserve sense, reference or truth [Fodor] |
2440 | Propositional attitudes are propositions presented in a certain way [Fodor] |
2988 | Folk psychology is the only explanation of behaviour we have [Fodor] |
3975 | Folk psychology explains behaviour by reference to intentional states like belief and desire [Fodor] |
2450 | Rationality has mental properties - autonomy, productivity, experiment [Fodor] |
2499 | Modules analyse stimuli, they don't tell you what to do [Fodor] |
2509 | Modules have in-built specialist information [Fodor] |
22186 | Mental modules are specialised, automatic, and isolated [Fodor, by Okasha] |
2491 | Modules have encapsulation, inaccessibility, private concepts, innateness [Fodor] |
2497 | Something must take an overview of the modules [Fodor] |
2495 | Obvious modules are language and commonsense explanation [Fodor] |
2496 | Blindness doesn't destroy spatial concepts [Fodor] |
2507 | Rationality rises above modules [Fodor] |
2498 | Modules make the world manageable [Fodor] |
2500 | Babies talk in consistent patterns [Fodor] |
2487 | Mentalese may also incorporate some natural language [Fodor] |
2483 | Mentalese doesn't require a theory of meaning [Fodor] |
2480 | Language is ambiguous, but thought isn't [Fodor] |
8090 | Since the language of thought is the same for all, it must be something like logical form [Fodor, by Devlin] |
3010 | Belief and desire are structured states, which need mentalese [Fodor] |
2604 | We must have expressive power BEFORE we learn language [Fodor] |
12643 | Ambiguities in English are the classic reason for claiming that we don't think in English [Fodor] |
12647 | Mental representations name things in the world, but also files in our memory [Fodor] |
12649 | We think in file names [Fodor] |
3135 | Is thought a syntactic computation using representations? [Fodor, by Rey] |
12655 | Frame Problem: how to eliminate most beliefs as irrelevant, without searching them? [Fodor] |
2983 | Maybe narrow content is physical, broad content less so [Lyons on Fodor] |
12615 | Mental representations are the old 'Ideas', but without images [Fodor] |
2437 | XYZ (Twin Earth 'water') is an impossibility [Fodor] |
12630 | If concept content is reference, then my Twin and I are referring to the same stuff [Fodor] |
3982 | How could the extrinsic properties of thoughts supervene on their intrinsic properties? [Fodor] |
2441 | Truth conditions require a broad concept of content [Fodor] |
2999 | Obsession with narrow content leads to various sorts of hopeless anti-realism [Fodor] |
3114 | Concepts aren't linked to stuff; they are what is caused by stuff [Fodor] |
2486 | Content can't be causal role, because causal role is decided by content [Fodor] |
3012 | Do identical thoughts have identical causal roles? [Fodor] |
2452 | Knowing the cause of a thought is almost knowing its content [Fodor] |
2432 | Is content basically information, fixed externally? [Fodor] |
12658 | Nobody knows how concepts are acquired [Fodor] |
2492 | Experience can't explain itself; the concepts needed must originate outside experience [Fodor] |
11143 | If concept-learning is hypothesis-testing, that needs innate concepts to get started [Fodor, by Margolis/Laurence] |
6650 | Fodor is now less keen on the innateness of concepts [Fodor, by Lowe] |
12662 | We have an innate capacity to form a concept, once we have grasped the stereotype [Fodor] |
12618 | It is essential to the concept CAT that it be satisfied by cats [Fodor] |
12635 | Having a concept isn't a pragmatic matter, but being able to think about the concept [Fodor] |
12652 | Concepts have two sides; they are files that face thought, and also face subject-matter [Fodor] |
2438 | In the information view, concepts are potentials for making distinctions [Fodor] |
12614 | I prefer psychological atomism - that concepts are independent of epistemic capacities [Fodor] |
2471 | Are concepts best seen as capacities? [Fodor] |
2472 | For Pragmatists having a concept means being able to do something [Fodor] |
12626 | Cartesians put concept individuation before concept possession [Fodor] |
