1. Philosophy / A. Wisdom / 3. Wisdom Deflated
Inspiration and social improvement need wisdom, but not professional philosophy [Quine]
1. Philosophy / D. Nature of Philosophy / 6. Hopes for Philosophy
For a good theory of the world, we must focus on our flabby foundational vocabulary [Quine]
1. Philosophy / E. Nature of Metaphysics / 1. Nature of Metaphysics
Maybe analysis seeks the 'nominal essence', and metaphysics seeks the 'real essence' [Locke, by Mumford]
Quinean metaphysics just lists the beings, which is a domain with no internal structure [Schaffer,J on Quine]
1. Philosophy / E. Nature of Metaphysics / 3. Metaphysical Systems
Any statement can be held true if we make enough adjustment to the rest of the system [Quine]
1. Philosophy / E. Nature of Metaphysics / 4. Metaphysics as Science
I am just an under-labourer, clearing the ground in preparation for knowledge [Locke]
Quine rejects Carnap's view that science and philosophy are distinct [Quine, by Boulter]
Philosophy is largely concerned with finding the minimum that science could get by with [Quine]
Quine's naturalistic and empirical view is based entirely on first-order logic and set theory [Quine, by Mautner]
1. Philosophy / E. Nature of Metaphysics / 6. Metaphysics as Conceptual
Enquiry needs a conceptual scheme, so we should retain the best available [Quine]
We aren't stuck with our native conceptual scheme; we can gradually change it [Quine]
1. Philosophy / F. Analytic Philosophy / 6. Logical Analysis
If if time is money then if time is not money then time is money then if if if time is not money... [Quine]
Logicians don't paraphrase logic into language, because they think in the symbolic language [Quine]
1. Philosophy / G. Scientific Philosophy / 3. Scientism
Philosophy is continuous with science, and has no external vantage point [Quine]
2. Reason / A. Nature of Reason / 7. Status of Reason
Opposition to reason is mad [Locke]
2. Reason / B. Laws of Thought / 3. Non-Contradiction
If you say that a contradiction is true, you change the meaning of 'not', and so change the subject [Quine]
To affirm 'p and not-p' is to have mislearned 'and' or 'not' [Quine]
2. Reason / B. Laws of Thought / 6. Ockham's Razor
Good algorithms and theories need many occurrences of just a few elements [Quine]
The quest for simplicity drove scientists to posit new entities, such as molecules in gases [Quine]
In arithmetic, ratios, negatives, irrationals and imaginaries were created in order to generalise [Quine]
2. Reason / D. Definition / 1. Definitions
Definition rests on synonymy, rather than explaining it [Quine]
2. Reason / D. Definition / 5. Genus and Differentia
Genus is a partial conception of species, and species a partial idea of individuals [Locke]
2. Reason / D. Definition / 6. Definition by Essence
Maybe Locke described the real essence of a person [Locke, by Pasnau]
2. Reason / D. Definition / 7. Contextual Definition
Contextual definition shifted the emphasis from words to whole sentences [Quine]
Definition by words is determinate but relative; fixing contexts could make it absolute [Quine]
Bentham's contextual definitions preserved terms after their denotation became doubtful [Quine]
2. Reason / D. Definition / 12. Paraphrase
Russell offered a paraphrase of definite description, to avoid the commitment to objects [Quine]
2. Reason / F. Fallacies / 1. Fallacy
The Struthionic Fallacy is that of burying one's head in the sand [Quine]
2. Reason / F. Fallacies / 7. Ad Hominem
Ad Hominem: press a man with the consequences of his own principle [Locke]
2. Reason / F. Fallacies / 8. Category Mistake / a. Category mistakes
Asking whether man's will is free is liking asking if sleep is fast or virtue is square [Locke]
3. Truth / A. Truth Problems / 3. Value of Truth
Nothing is so beautiful to the eye as truth is to the mind [Locke]
3. Truth / A. Truth Problems / 5. Truth Bearers
Truth only belongs to mental or verbal propositions [Locke]
It is propositions which are true or false, though it is sometimes said of ideas [Locke]
If they refer to real substances, 'man' is a true idea and 'centaur' a false one [Locke]
3. Truth / C. Correspondence Truth / 1. Correspondence Truth
Science is sympathetic to truth as correspondence, since it depends on observation [Quine]
3. Truth / F. Semantic Truth / 2. Semantic Truth
Talk of 'truth' when sentences are mentioned; it reminds us that reality is the point of sentences [Quine]
3. Truth / H. Deflationary Truth / 1. Redundant Truth
Truth is redundant for single sentences; we do better to simply speak the sentence [Quine]
4. Formal Logic / A. Syllogistic Logic / 2. Syllogistic Logic
Many people can reason well, yet can't make a syllogism [Locke]
Syllogisms are verbal fencing, not discovery [Locke]
4. Formal Logic / B. Propositional Logic PL / 2. Tools of Propositional Logic / a. Symbols of PL
The logician's '→' does not mean the English if-then [Quine]
4. Formal Logic / B. Propositional Logic PL / 2. Tools of Propositional Logic / e. Axioms of PL
We can eliminate 'or' from our basic theory, by paraphrasing 'p or q' as 'not(not-p and not-q)' [Quine]
4. Formal Logic / D. Modal Logic ML / 1. Modal Logic
Maybe we can quantify modally if the objects are intensional, but it seems unlikely [Quine]
Quine says quantified modal logic creates nonsense, bad ontology, and false essentialism [Melia on Quine]
Quantified modal logic collapses if essence is withdrawn [Quine]
4. Formal Logic / D. Modal Logic ML / 6. Temporal Logic
It is important that the quantification over temporal entities is timeless [Quine]
4. Formal Logic / F. Set Theory ST / 1. Set Theory
Set theory is full of Platonist metaphysics, so Quine aimed to keep it separate from logic [Quine, by Benardete,JA]
4. Formal Logic / F. Set Theory ST / 4. Axioms for Sets / a. Axioms for sets
NF has no models, but just blocks the comprehension axiom, to avoid contradictions [Quine, by Dummett]
4. Formal Logic / F. Set Theory ST / 4. Axioms for Sets / o. Axiom of Constructibility V = L
Quine wants V = L for a cleaner theory, despite the scepticism of most theorists [Quine, by Shapiro]
4. Formal Logic / F. Set Theory ST / 4. Axioms for Sets / p. Axiom of Reducibility
Reducibility undermines type ramification, and is committed to the existence of functions [Quine, by Linsky,B]
The Axiom of Reducibility is self-effacing: if true, it isn't needed [Quine]
4. Formal Logic / F. Set Theory ST / 5. Conceptions of Set / d. Naïve logical sets
The set scheme discredited by paradoxes is actually the most natural one [Quine]
4. Formal Logic / F. Set Theory ST / 7. Natural Sets
Russell's antinomy challenged the idea that any condition can produce a set [Quine]
4. Formal Logic / F. Set Theory ST / 8. Critique of Set Theory
Two things can never entail three things [Quine, by Benardete,JA]
5. Theory of Logic / A. Overview of Logic / 1. Overview of Logic
My logical grammar has sentences by predication, then negation, conjunction, and existential quantification [Quine]
In order to select the logic justified by experience, we would need to use a lot of logic [Boghossian on Quine]
5. Theory of Logic / A. Overview of Logic / 3. Value of Logic
Maybe logical truth reflects reality, but in different ways in different languages [Quine]
5. Theory of Logic / A. Overview of Logic / 6. Classical Logic
Elementary logic requires truth-functions, quantifiers (and variables), identity, and also sets of variables [Quine]
5. Theory of Logic / A. Overview of Logic / 7. Second-Order Logic
Quine says higher-order items are intensional, and lack a clearly defined identity relation [Quine, by Shapiro]
Various strategies try to deal with the ontological commitments of second-order logic [Hale/Wright on Quine]
Quine rejects second-order logic, saying that predicates refer to multiple objects [Quine, by Hodes]
Quantifying over predicates is treating them as names of entities [Quine]
5. Theory of Logic / B. Logical Consequence / 1. Logical Consequence
Logical consequence is marked by being preserved under all nonlogical substitutions [Quine, by Sider]
5. Theory of Logic / C. Ontology of Logic / 1. Ontology of Logic
Whether a modal claim is true depends on how the object is described [Quine, by Fine,K]
Logical languages are rooted in ordinary language, and that connection must be kept [Quine]
5. Theory of Logic / C. Ontology of Logic / 3. If-Thenism
Quine quickly dismisses If-thenism [Quine, by Musgrave]
Mathematical proofs work, irrespective of whether the objects exist [Locke]
5. Theory of Logic / C. Ontology of Logic / 4. Logic by Convention
Logic needs general conventions, but that needs logic to apply them to individual cases [Quine, by Rey]
Claims that logic and mathematics are conventional are either empty, uninteresting, or false [Quine]
Logic isn't conventional, because logic is needed to infer logic from conventions [Quine]
If a convention cannot be communicated until after its adoption, what is its role? [Quine]
5. Theory of Logic / D. Assumptions for Logic / 1. Bivalence
Bivalence applies not just to sentences, but that general terms are true or false of each object [Quine]
5. Theory of Logic / D. Assumptions for Logic / 2. Excluded Middle
Excluded middle has three different definitions [Quine]
5. Theory of Logic / D. Assumptions for Logic / 4. Identity in Logic
Quantification theory can still be proved complete if we add identity [Quine]
5. Theory of Logic / E. Structures of Logic / 1. Logical Form
Reduction to logical forms first simplifies idioms and grammar, then finds a single reading of it [Quine]
5. Theory of Logic / E. Structures of Logic / 2. Logical Connectives / a. Logical connectives
If logical truths essentially depend on logical constants, we had better define the latter [Hacking on Quine]
5. Theory of Logic / E. Structures of Logic / 4. Variables in Logic
We study bound variables not to know reality, but to know what reality language asserts [Quine]
'Corner quotes' (quasi-quotation) designate 'whatever these terms designate' [Quine]
5. Theory of Logic / E. Structures of Logic / 6. Relations in Logic
All relations, apart from ancestrals, can be reduced to simpler logic [Quine]
5. Theory of Logic / F. Referring in Logic / 1. Naming / a. Names
If we had to name objects to make existence claims, we couldn't discuss all the real numbers [Quine]
5. Theory of Logic / F. Referring in Logic / 1. Naming / b. Names as descriptive
Failure of substitutivity shows that a personal name is not purely referential [Quine]
5. Theory of Logic / F. Referring in Logic / 1. Naming / f. Names eliminated
We might do without names, by converting them into predicates [Quine, by Kirkham]
Canonical notation needs quantification, variables and predicates, but not names [Quine, by Orenstein]
Quine extended Russell's defining away of definite descriptions, to also define away names [Quine, by Orenstein]
Quine's arguments fail because he naively conflates names with descriptions [Fine,K on Quine]
Names are not essential, because naming can be turned into predication [Quine]
5. Theory of Logic / F. Referring in Logic / 2. Descriptions / c. Theory of definite descriptions
Names can be converted to descriptions, and Russell showed how to eliminate those [Quine]
5. Theory of Logic / G. Quantification / 1. Quantification
Quantifying into referentially opaque contexts often produces nonsense [Quine]
Objects are the values of variables, so a referentially opaque context cannot be quantified into [Quine]
No sense can be made of quantification into opaque contexts [Quine, by Hale]
Finite quantification can be eliminated in favour of disjunction and conjunction [Quine, by Dummett]
Universal quantification is widespread, but it is definable in terms of existential quantification [Quine]
5. Theory of Logic / G. Quantification / 4. Substitutional Quantification
Quine thought substitutional quantification confused use and mention, but then saw its nominalist appeal [Quine, by Marcus (Barcan)]
Either reference really matters, or we don't need to replace it with substitutions [Quine]
If quantification is all substitutional, there is no ontology [Quine]
You can't base quantification on substituting names for variables, if the irrationals cannot all be named [Quine]
Some quantifications could be false substitutionally and true objectually, because of nameless objects [Quine]
5. Theory of Logic / G. Quantification / 5. Second-Order Quantification
Putting a predicate letter in a quantifier is to make it the name of an entity [Quine]
5. Theory of Logic / G. Quantification / 6. Plural Quantification
Plurals can in principle be paraphrased away altogether [Quine]
5. Theory of Logic / I. Semantics of Logic / 3. Logical Truth
A sentence is logically true if all sentences with that grammatical structure are true [Quine]
5. Theory of Logic / L. Paradox / 3. Antinomies
Antinomies contradict accepted ways of reasoning, and demand revisions [Quine]
5. Theory of Logic / L. Paradox / 4. Paradoxes in Logic / a. Achilles paradox
Whenever the pursuer reaches the spot where the pursuer has been, the pursued has moved on [Quine]
5. Theory of Logic / L. Paradox / 5. Paradoxes in Set Theory / a. Set theory paradoxes
Set theory was struggling with higher infinities, when new paradoxes made it baffling [Quine]
5. Theory of Logic / L. Paradox / 5. Paradoxes in Set Theory / d. Russell's paradox
A barber shaves only those who do not shave themselves. So does he shave himself? [Quine]
Membership conditions which involve membership and non-membership are paradoxical [Quine]
5. Theory of Logic / L. Paradox / 6. Paradoxes in Language / a. The Liar paradox
If we write it as '"this sentence is false" is false', there is no paradox [Quine]
6. Mathematics / A. Nature of Mathematics / 2. Geometry
Klein summarised geometry as grouped together by transformations [Quine]
If analytic geometry identifies figures with arithmetical relations, logicism can include geometry [Quine]
6. Mathematics / A. Nature of Mathematics / 3. Nature of Numbers / e. Ordinal numbers
Any progression will do nicely for numbers; they can all then be used to measure multiplicity [Quine]
6. Mathematics / A. Nature of Mathematics / 3. Nature of Numbers / m. One
The idea of 'one' is the simplest, most obvious and most widespread idea [Locke]
6. Mathematics / A. Nature of Mathematics / 5. The Infinite / d. Actual infinite
If there were real infinities, you could add two together, which is ridiculous [Locke]
6. Mathematics / B. Foundations for Mathematics / 3. Axioms for Geometry
There are four different possible conventional accounts of geometry [Quine]
6. Mathematics / B. Foundations for Mathematics / 6. Mathematics as Set Theory / a. Mathematics is set theory
Maths can be reduced to logic and set theory [Quine]
All the arithmetical entities can be reduced to classes of integers, and hence to sets [Quine]
6. Mathematics / B. Foundations for Mathematics / 7. Mathematical Structuralism / a. Structuralism
I apply structuralism to concrete and abstract objects indiscriminately [Quine]
6. Mathematics / C. Sources of Mathematics / 1. Mathematical Platonism / b. Against mathematical platonism
Mathematics is just about ideas, so whether circles exist is irrelevant [Locke]
6. Mathematics / C. Sources of Mathematics / 3. Mathematical Nominalism
Nominalism rejects both attributes and classes (where extensionalism accepts the classes) [Quine]
6. Mathematics / C. Sources of Mathematics / 4. Mathematical Empiricism / a. Mathematical empiricism
Quine blurs the difference between knowledge of arithmetic and of physics [Jenkins on Quine]
Every simple idea we ever have brings the idea of unity along with it [Locke]
6. Mathematics / C. Sources of Mathematics / 4. Mathematical Empiricism / b. Indispensability of mathematics
Nearly all of mathematics has to quantify over abstract objects [Quine]
Mathematics is part of science; transfinite mathematics I take as mostly uninterpreted [Quine]
6. Mathematics / C. Sources of Mathematics / 6. Logicism / a. Early logicism
If mathematics follows from definitions, then it is conventional, and part of logic [Quine]
6. Mathematics / C. Sources of Mathematics / 6. Logicism / b. Type theory
Russell confused use and mention, and reduced classes to properties, not to language [Quine, by Lackey]
6. Mathematics / C. Sources of Mathematics / 6. Logicism / d. Logicism critique
Logicists cheerfully accept reference to bound variables and all sorts of abstract entities [Quine]
If set theory is not actually a branch of logic, then Frege's derivation of arithmetic would not be from logic [Quine]
Mathematics reduces to set theory (which is a bit vague and unobvious), but not to logic proper [Quine]
6. Mathematics / C. Sources of Mathematics / 7. Formalism
Formalism says maths is built of meaningless notations; these build into rules which have meaning [Quine]
6. Mathematics / C. Sources of Mathematics / 10. Constructivism / b. Intuitionism
Intuitionism says classes are invented, and abstract entities are constructed from specified ingredients [Quine]
For Quine, intuitionist ontology is inadequate for classical mathematics [Quine, by Orenstein]
Intuitionists only admit numbers properly constructed, but classical maths covers all reals in a 'limit' [Quine, by Orenstein]
6. Mathematics / C. Sources of Mathematics / 10. Constructivism / c. Conceptualism
Conceptualism holds that there are universals but they are mind-made [Quine]
7. Existence / A. Nature of Existence / 2. Types of Existence
For Quine, there is only one way to exist [Quine, by Shapiro]
7. Existence / A. Nature of Existence / 3. Being / b. Being and existence
Philosophers tend to distinguish broad 'being' from narrower 'existence' - but I reject that [Quine]
7. Existence / A. Nature of Existence / 3. Being / g. Particular being
The idea of a thing and the idea of existence are two sides of the same coin [Quine, by Crane]
7. Existence / A. Nature of Existence / 4. Abstract Existence
General and universal are not real entities, but useful inventions of the mind, concerning words or ideas [Locke]
7. Existence / A. Nature of Existence / 6. Criterion for Existence
Existences can only be known by experience [Locke]
Absolute ontological questions are meaningless, because the answers are circular definitions [Quine]
Quine rests existence on bound variables, because he thinks singular terms can be analysed away [Quine, by Hale]
All we have of general existence is what existential quantifiers express [Quine]
7. Existence / B. Change in Existence / 2. Processes
A river is a process, with stages; if we consider it as one thing, we are considering a process [Quine]
7. Existence / B. Change in Existence / 4. Events / c. Reduction of events
Explaining events just by bodies can't explain two events identical in space-time [Quine]
7. Existence / C. Structure of Existence / 6. Fundamentals / d. Logical atoms
Comparisons boil down to simple elements of sensation or reflection [Locke]
7. Existence / C. Structure of Existence / 7. Abstract/Concrete / a. Abstract/concrete
We can only see an alien language in terms of our own thought structures (e.g. physical/abstract) [Quine]
We don't say 'red' is abstract, unlike a river, just because it has discontinuous shape [Quine]
7. Existence / C. Structure of Existence / 8. Stuff / a. Pure stuff
Mass terms just concern spread, but other terms involve both spread and individuation [Quine]
7. Existence / D. Theories of Reality / 1. Ontologies
Quine's ontology is wrong; his question is scientific, and his answer is partly philosophical [Fine,K on Quine]
7. Existence / D. Theories of Reality / 2. Realism
God assures me of the existence of external things [Locke]
7. Existence / D. Theories of Reality / 6. Physicalism
Every worldly event, without exception, is a redistribution of microphysical states [Quine]
My ontology is quarks etc., classes of such things, classes of such classes etc. [Quine]
7. Existence / D. Theories of Reality / 10. Vagueness / c. Vagueness as ignorance
Obscure simple ideas result from poor senses, brief impressions, or poor memory [Locke]
Ideas are uncertain when they are unnamed, because too close to other ideas [Locke]
7. Existence / D. Theories of Reality / 10. Vagueness / d. Vagueness as linguistic
Terms learned by ostension tend to be vague, because that must be quick and unrefined [Quine]
7. Existence / D. Theories of Reality / 11. Ontological Commitment / a. Ontological commitment
What actually exists does not, of course, depend on language [Quine]
General terms don't commit us ontologically, but singular terms with substitution do [Quine]
Names have no ontological commitment, because we can deny that they name anything [Quine]
A logically perfect language could express all truths, so all truths must be logically expressible [Quine, by Hossack]
7. Existence / D. Theories of Reality / 11. Ontological Commitment / b. Commitment of quantifiers
To be is to be the value of a variable, which amounts to being in the range of reference of a pronoun [Quine]
We can use quantification for commitment to unnameable things like the real numbers [Quine]
"No entity without identity" - our ontology must contain items with settled identity conditions [Quine, by Melia]
Existence is implied by the quantifiers, not by the constants [Quine]
7. Existence / D. Theories of Reality / 11. Ontological Commitment / c. Commitment of predicates
Quine says we can expand predicates easily (ideology), but not names (ontology) [Quine, by Noonan]
Theories are committed to objects of which some of its predicates must be true [Quine]
7. Existence / D. Theories of Reality / 11. Ontological Commitment / d. Commitment of theories
Fictional quantification has no ontology, so we study ontology through scientific theories [Quine, by Orenstein]
An ontology is like a scientific theory; we accept the simplest scheme that fits disorderly experiences [Quine]
Express a theory in first-order predicate logic; its ontology is the types of bound variable needed for truth [Quine, by Lowe]
Ontological commitment of theories only arise if they are classically quantified [Quine]
Ontology is relative to both a background theory and a translation manual [Quine]
For Quine everything exists theoretically, as reference, predication and quantification [Quine, by Benardete,JA]
7. Existence / D. Theories of Reality / 11. Ontological Commitment / e. Ontological commitment problems
If commitment rests on first-order logic, we obviously lose the ontology concerning predication [Maudlin on Quine]
If to be is to be the value of a variable, we must already know the values available [Jacquette on Quine]
Quine is hopeless circular, deriving ontology from what is literal, and 'literal' from good ontology [Yablo on Quine]
You can be implicitly committed to something without quantifying over it [Thomasson on Quine]
7. Existence / E. Categories / 1. Categories
In formal terms, a category is the range of some style of variables [Quine]
7. Existence / E. Categories / 2. Categorisation
We can't categorise things by their real essences, because these are unknown [Locke]
If we discovered real essences, we would still categorise things by the external appearance [Locke]
7. Existence / E. Categories / 4. Category Realism
The quest for ultimate categories is the quest for a simple clear pattern of notation [Quine]
7. Existence / E. Categories / 5. Category Anti-Realism
There are no gaps in the continuum of nature, and everything has something closely resembling it [Locke]
Discourse generally departmentalizes itself to some degree [Quine]
8. Modes of Existence / B. Properties / 1. Nature of Properties
The category of objects incorporates the old distinction of substances and their modes [Quine]
8. Modes of Existence / B. Properties / 10. Properties as Predicates
Quine says the predicate of a true statement has no ontological implications [Quine, by Armstrong]
8. Modes of Existence / B. Properties / 12. Denial of Properties
There is no proper identity concept for properties, and it is hard to distinguish one from two [Quine]
Quine suggests that properties can be replaced with extensional entities like sets [Quine, by Shapiro]
Quine says that if second-order logic is to quantify over properties, that can be done in first-order predicate logic [Quine, by Benardete,JA]
Quine brought classes into semantics to get rid of properties [Quine, by McGinn]
Predicates are not names; predicates are the other parties to predication [Quine]
Don't analyse 'red is a colour' as involving properties. Say 'all red things are coloured things' [Quine, by Orenstein]
Because things can share attributes, we cannot individuate attributes clearly [Quine]
8. Modes of Existence / C. Powers and Dispositions / 1. Powers
We get the idea of power from our own actions, and the interaction of external bodies [Locke]
Power is active or passive, and has a relation to actions [Locke]
We can only know a thing's powers when we have combined it with many things [Locke]
8. Modes of Existence / C. Powers and Dispositions / 3. Powers as Derived
The essence of whiteness in a man is nothing but the power to produce the idea of whiteness [Locke]
Dispositions are physical states of mechanism; when known, these replace the old disposition term [Quine]
8. Modes of Existence / C. Powers and Dispositions / 4. Powers as Essence
What is the texture - the real essence - which makes substances behave in distinct ways? [Locke]
8. Modes of Existence / C. Powers and Dispositions / 6. Dispositions / a. Dispositions
Either dispositions rest on structures, or we keep saying 'all things being equal' [Quine]
Once we know the mechanism of a disposition, we can eliminate 'similarity' [Quine]
8. Modes of Existence / C. Powers and Dispositions / 6. Dispositions / d. Dispositions as occurrent
Explain unmanifested dispositions as structural similarities to objects which have manifested them [Quine, by Martin,CB]
We judge things to be soluble if they are the same kind as, or similar to, things that do dissolve [Quine]
8. Modes of Existence / C. Powers and Dispositions / 7. Against Powers
Locke explains powers, but effectively eliminates them with his talk of internal structure [Locke, by Alexander,P]
8. Modes of Existence / D. Universals / 1. Universals
Locke, Berkeley and Hume did no serious thinking about universals [Robinson,H on Locke]
Realism, conceptualism and nominalism in medieval universals reappear in maths as logicism, intuitionism and formalism [Quine]
8. Modes of Existence / D. Universals / 2. Need for Universals
Universals are acceptable if they are needed to make an accepted theory true [Quine, by Jacquette]
8. Modes of Existence / E. Nominalism / 1. Nominalism / b. Nominalism about universals
All things that exist are particulars [Locke]
Universals do not exist, but are useful inventions of the mind, involving words or ideas [Locke]
There is no entity called 'redness', and that some things are red is ultimate and irreducible [Quine]
Commitment to universals is as arbitrary or pragmatic as the adoption of a new system of bookkeeping [Quine]
8. Modes of Existence / E. Nominalism / 3. Predicate Nominalism
Quine has argued that predicates do not have any ontological commitment [Quine, by Armstrong]
8. Modes of Existence / E. Nominalism / 4. Concept Nominalism
Understanding 'is square' is knowing when to apply it, not knowing some object [Quine]
8. Modes of Existence / E. Nominalism / 5. Class Nominalism
Quine aims to deal with properties by the use of eternal open sentences, or classes [Quine, by Devitt]
Quine is committed to sets, but is more a Class Nominalist than a Platonist [Quine, by Macdonald,C]
You only know an attribute if you know what things have it [Quine]
8. Modes of Existence / E. Nominalism / 6. Mereological Nominalism
Red is the largest red thing in the universe [Quine]
'Red' is a single concrete object in space-time; 'red' and 'drop' are parts of a red drop [Quine]
9. Objects / A. Existence of Objects / 1. Physical Objects
The notion of a physical object is by far the most useful one for science [Quine]
If physical objects are a myth, they are useful for making sense of experience [Quine]
Bodies distinctively have cohesion of parts, and power to communicate motion [Locke]
Treating scattered sensations as single objects simplifies our understanding of experience [Quine]
Physical objects in space-time are just events or processes, no matter how disconnected [Quine]
A physical object is the four-dimensional material content of a portion of space-time [Quine]
9. Objects / A. Existence of Objects / 2. Abstract Objects / b. Need for abstracta
Our conceptual scheme becomes more powerful when we posit abstract objects [Quine]
9. Objects / A. Existence of Objects / 4. Impossible objects
Definite descriptions can't unambiguously pick out an object which doesn't exist [Lycan on Quine]
9. Objects / A. Existence of Objects / 5. Individuation / a. Individuation
Viewing an object at an instant, we perceive identity when we see it must be that thing and not another [Locke]
Living things retain identity through change, by a principle of organisation [Locke]
I prefer 'no object without identity' to Quine's 'no entity without identity' [Lowe on Quine]
No entity without identity (which requires a principle of individuation) [Quine]
9. Objects / A. Existence of Objects / 5. Individuation / c. Individuation by location
A thing is individuated just by existing at a time and place [Locke]
Obviously two bodies cannot be in the same place [Locke]
9. Objects / A. Existence of Objects / 5. Individuation / e. Individuation by kind
I speak of a 'sortal' name, from the word 'sort' [Locke]
9. Objects / B. Unity of Objects / 2. Substance / a. Substance
Powers are part of our idea of substances [Locke]
9. Objects / B. Unity of Objects / 2. Substance / c. Types of substance
We can conceive of three sorts of substance: God, finite intelligence, and bodies [Locke]
We sort and name substances by nominal and not by real essence [Locke]
9. Objects / B. Unity of Objects / 2. Substance / d. Substance defined
We think of substance as experienced qualities plus a presumed substratum of support [Locke]
9. Objects / B. Unity of Objects / 2. Substance / e. Substance critique
We don't know what substance is, and only vaguely know what it does [Locke]
9. Objects / B. Unity of Objects / 3. Unity Problems / d. Coincident objects
Locke may accept coinciding material substances, such as body, man and person [Locke, by Pasnau]
9. Objects / C. Structure of Objects / 5. Composition of an Object
A mass consists of its atoms, so the addition or removal of one changes its identity [Locke]
9. Objects / C. Structure of Objects / 7. Substratum
Complex ideas are collections of qualities we attach to an unknown substratum [Locke]
9. Objects / D. Essence of Objects / 1. Essences of Objects
Particular substances are coexisting ideas that seem to flow from a hidden essence [Locke]
The best I can make of real essence is figure, size and connection of solid parts [Locke]
Real essence is the constitution of the unknown parts of a body which produce its qualities [Locke]
9. Objects / D. Essence of Objects / 2. Types of Essence
Locke may distinguish real essence from internal constitution, claiming the latter is knowable [Locke, by Jones,J-E]
9. Objects / D. Essence of Objects / 3. Individual Essences
We can conceive an individual without assigning it to a kind [Locke, by Jolley]
You can't distinguish individuals without the species as a standard [Locke]
Many individuals grouped under one name vary more than some things that have different names [Locke]
Every individual thing which exists has an essence, which is its internal constitution [Locke]
9. Objects / D. Essence of Objects / 5. Essence as Kind
The less rational view of essences is that they are moulds for kinds of natural thing [Locke]
Even real essence depends on a sort, since it is sorts which have the properties [Locke]
If every sort has its real essence, one horse, being many sorts, will have many essences [Locke]
9. Objects / D. Essence of Objects / 6. Essence as Unifier
Not all identity is unity of substance [Locke]
Essence is the very being of any thing, whereby it is what it is [Locke]
9. Objects / D. Essence of Objects / 7. Essence and Necessity / c. Essentials are necessary
We can only slightly know necessary co-existence of qualities, if they are primary [Locke]
9. Objects / D. Essence of Objects / 8. Essence as Explanatory
Explanatory essence won't do, because it won't distinguish the accidental from the essential [Locke, by Pasnau]
9. Objects / D. Essence of Objects / 9. Essence and Properties
Lockean real essence makes a thing what it is, and produces its observable qualities [Locke, by Jones,J-E]
Locke's essences determine the other properties, so the two will change together [Locke, by Copi]
It is impossible for two things with the same real essence to differ in properties [Locke]
We cannot know what properties are necessary to gold, unless we first know its real essence [Locke]
Aristotelian essentialism says a thing has some necessary and some non-necessary properties [Quine]
9. Objects / D. Essence of Objects / 10. Essence as Species
In our ideas, the idea of essence is inseparable from the concept of a species [Locke]
If we based species on real essences, the individuals would be as indistinguishable as two circles [Locke]
Internal constitution doesn't decide a species; should a watch contain four wheels or five? [Locke]
9. Objects / D. Essence of Objects / 11. Essence of Artefacts
Artificial things like watches and pistols have distinct kinds [Locke]
9. Objects / D. Essence of Objects / 13. Nominal Essence
Things have real essences, but we categorise them according to the ideas we receive [Locke]
Real essence explains observable qualities, but not what kind of thing it is [Locke, by Jones,J-E]
If essence is 'nominal', artificial gold (with its surface features) would qualify as 'gold' [Locke, by Eagle]
'Nominal essence' is everything contained in the idea of a particular sort of thing [Locke, by Copi]
The observable qualities are never the real essence, since they depend on real essence [Locke]
In nominal essence, Locke confuses the set of properties with the abstracted idea of them [Eagle on Locke]
To be a nominal essence, a complex idea must exhibit unity [Locke]
Locke's real and nominal essence refers back to Aristotle's real and nominal definitions [Locke, by Jones,J-E]
Nominal Essence is the abstract idea to which a name is attached [Locke]
Essences relate to sorting words; if you replace those with names, essences vanish [Locke]
Real essences are unknown, so only the nominal essence connects things to a species [Locke]
Our ideas of substance are based on mental archetypes, but these come from the world [Locke]
For 'all gold is malleable' to be necessary, it must be part of gold's nominal essence [Locke]
9. Objects / D. Essence of Objects / 14. Knowledge of Essences
The essence of a triangle is simple; presumably substance essences are similar [Locke]
A space between three lines is both the nominal and real essence of a triangle, the source of its properties [Locke]
The schools recognised that they don't really know essences, because they couldn't coin names for them [Locke]
9. Objects / D. Essence of Objects / 15. Against Essentialism
There are no independent natural kinds - or our classifications have to be subjective [Locke, by Jolley]
We know five properties of gold, but cannot use four of them to predict the fifth one [Locke]
Aristotelian essence of the object has become the modern essence of meaning [Quine]
Quantification into modal contexts requires objects to have an essence [Quine]
Mathematicians must be rational but not two-legged, cyclists the opposite. So a mathematical cyclist? [Quine]
Cyclist are not actually essentially two-legged [Brody on Quine]
Essences can make sense in a particular context or enquiry, as the most basic predicates [Quine]
9. Objects / E. Objects over Time / 1. Objects over Time
Identity means that the idea of a thing remains the same over time [Locke]
9. Objects / E. Objects over Time / 4. Four-Dimensionalism
Four-d objects helps predication of what no longer exists, and quantification over items from different times [Quine]
9. Objects / E. Objects over Time / 7. Intermittent Objects
One thing cannot have two beginnings of existence, nor two things one beginning [Locke]
9. Objects / F. Identity among Objects / 1. Concept of Identity
To unite a sequence of ostensions to make one object, a prior concept of identity is needed [Quine]
We know what things are by distinguishing them, so identity is part of ontology [Quine]
9. Objects / F. Identity among Objects / 2. Defining Identity
We can paraphrase 'x=y' as a sequence of the form 'if Fx then Fy' [Quine]
9. Objects / F. Identity among Objects / 3. Relative Identity
Same person, man or substance are different identities, belonging to different ideas [Locke]
9. Objects / F. Identity among Objects / 5. Self-Identity
Two things can't occupy one place and time, which leads us to the idea of self-identity [Locke]
9. Objects / F. Identity among Objects / 6. Identity between Objects
Identity of physical objects is just being coextensive [Quine]
9. Objects / F. Identity among Objects / 7. Indiscernible Objects
We should just identify any items which are indiscernible within a given discourse [Quine]
10. Modality / A. Necessity / 2. Nature of Necessity
Necessity can attach to statement-names, to statements, and to open sentences [Quine]
10. Modality / A. Necessity / 4. De re / De dicto modality
To be necessarily greater than 7 is not a trait of 7, but depends on how 7 is referred to [Quine]
10. Modality / A. Necessity / 6. Logical Necessity
Contrary to some claims, Quine does not deny logical necessity [Quine, by McFetridge]
Frege moved Kant's question about a priori synthetic to 'how is logical certainty possible?' [Quine]
10. Modality / A. Necessity / 11. Denial of Necessity
Whether 9 is necessarily greater than 7 depends on how '9' is described [Quine, by Fine,K]
Quine's attack on the analytic-synthetic distinction undermined necessary truths [Quine, by Shoemaker]
Necessity only applies to objects if they are distinctively specified [Quine]
Necessity is in the way in which we say things, and not things themselves [Quine]
There is no necessity higher than natural necessity, and that is just regularity [Quine]
Necessity could be just generalisation over classes, or (maybe) quantifying over possibilia [Quine]
Necessity is relative to context; it is what is assumed in an inquiry [Quine]
10. Modality / B. Possibility / 1. Possibility
Quine wants identity and individuation-conditions for possibilia [Quine, by Lycan]
10. Modality / B. Possibility / 8. Conditionals / b. Types of conditional
Some conditionals can be explained just by negation and conjunction: not(p and not-q) [Quine]
10. Modality / B. Possibility / 8. Conditionals / c. Truth-function conditionals
Normal conditionals have a truth-value gap when the antecedent is false. [Quine]
10. Modality / B. Possibility / 8. Conditionals / e. Supposition conditionals
Conditionals are pointless if the truth value of the antecedent is known [Quine]
Normally conditionals have no truth value; it is the consequent which has a conditional truth value [Quine]
10. Modality / B. Possibility / 9. Counterfactuals
We feign belief in counterfactual antecedents, and assess how convincing the consequent is [Quine]
Counterfactuals are plausible when dispositions are involved, as they imply structures [Quine]
Counterfactuals have no place in a strict account of science [Quine]
What stays the same in assessing a counterfactual antecedent depends on context [Quine]
10. Modality / D. Knowledge of Modality / 1. A Priori Necessary
Some of our ideas contain relations which we cannot conceive to be absent [Locke]
10. Modality / D. Knowledge of Modality / 3. A Posteriori Necessary
For Quine the only way to know a necessity is empirically [Quine, by Dancy,J]
Quine's indispensability argument said arguments for abstracta were a posteriori [Quine, by Yablo]
10. Modality / E. Possible worlds / 1. Possible Worlds / e. Against possible worlds
Possible worlds are a way to dramatise essentialism, and yet they presuppose essentialism [Quine]
10. Modality / E. Possible worlds / 3. Transworld Objects / a. Transworld identity
Can an unactualized possible have self-identity, and be distinct from other possibles? [Quine]
We can't quantify in modal contexts, because the modality depends on descriptions, not objects [Quine, by Fine,K]
10. Modality / E. Possible worlds / 3. Transworld Objects / b. Rigid designation
A rigid designator (for all possible worlds) picks out an object by its essential traits [Quine]
11. Knowledge Aims / A. Knowledge / 1. Knowledge
Our knowledge falls short of the extent of our own ideas [Locke]
11. Knowledge Aims / A. Knowledge / 4. Belief / a. Beliefs
Beliefs can be ascribed to machines [Quine]
11. Knowledge Aims / A. Knowledge / 4. Belief / d. Cause of beliefs
When two ideas agree in my mind, I cannot refuse to see and know it [Locke]
11. Knowledge Aims / A. Knowledge / 4. Belief / e. Belief holism
How do you distinguish three beliefs from four beliefs or two beliefs? [Quine]
11. Knowledge Aims / B. Certain Knowledge / 1. Certainty
The greatest certainty is knowing our own ideas, and that two ideas are different [Locke]
General certainty is only found in ideas [Locke]
If it is knowledge, it is certain; if it isn't certain, it isn't knowledge [Locke]
11. Knowledge Aims / B. Certain Knowledge / 3. Fallibilism
Knowledge by senses is less certain than that by intuition or reason, but it is still knowledge [Locke]
11. Knowledge Aims / B. Certain Knowledge / 4. The Cogito
I am as certain of the thing doubting, as I am of the doubt [Locke]
11. Knowledge Aims / C. Knowing Reality / 2. Phenomenalism
We can never translate our whole language of objects into phenomenalism [Quine]
12. Knowledge Sources / A. A Priori Knowledge / 2. Self-Evidence
A sentence is obvious if it is true, and any speaker of the language will instantly agree to it [Quine]
12. Knowledge Sources / A. A Priori Knowledge / 3. Innate Knowledge / a. Innate knowledge
Innate ideas are trivial (if they are just potentials) or absurd (if they claim infants know a lot) [Locke, by Jolley]
If the only test of innateness is knowing, then all of our knowledge is innate [Locke]
A proposition can't be in the mind if we aren't conscious of it [Locke]
Innate ideas were followed up with innate doctrines, which stopped reasoning and made social control possible [Locke]
12. Knowledge Sources / A. A Priori Knowledge / 3. Innate Knowledge / c. Tabula rasa
The senses first let in particular ideas, which furnish the empty cabinet [Locke]
The mind is white paper, with no writing, or ideas [Locke]
The mind is a blank page, on which only experience can write [Locke]
12. Knowledge Sources / A. A Priori Knowledge / 7. A Priori from Convention
Examination of convention in the a priori begins to blur the distinction with empirical knowledge [Quine]
12. Knowledge Sources / A. A Priori Knowledge / 8. A Priori as Analytic
Metaphysical analyticity (and linguistic necessity) are hopeless, but epistemic analyticity is a priori [Boghossian on Quine]
Quine challenges the claim that analytic truths are knowable a priori [Quine, by Kitcher]
12. Knowledge Sources / A. A Priori Knowledge / 10. A Priori as Subjective
The mind cannot produce simple ideas [Locke]
12. Knowledge Sources / A. A Priori Knowledge / 11. Denying the A Priori
Quine's objections to a priori knowledge only work in the domain of science [Horwich on Quine]
Science is empirical, simple and conservative; any belief can hence be abandoned; so no a priori [Quine, by Horwich]
Logic, arithmetic and geometry are revisable and a posteriori; quantum logic could be right [Horwich on Quine]
12. Knowledge Sources / B. Perception / 2. Qualities in Perception / a. Qualities in perception
A 'quality' is a power to produce an idea in our minds [Locke]
12. Knowledge Sources / B. Perception / 2. Qualities in Perception / b. Primary/secondary
Hands can report conflicting temperatures, but not conflicting shapes [Locke]
We can't know how primary and secondary qualities connect together [Locke]
Colours, smells and tastes are ideas; the secondary qualities have no colour, smell or taste [Locke, by Alexander,P]
Secondary qualities are powers of complex primary qualities to produce sensations in us [Locke]
12. Knowledge Sources / B. Perception / 2. Qualities in Perception / c. Primary qualities
Locke believes matter is an inert, senseless substance, with extension, figure and motion [Locke, by Berkeley]
Qualities are named as primary if they are needed for scientific explanation [Locke, by Alexander,P]
Primary qualities produce simple ideas, such as solidity, extension, motion and number [Locke]
Ideas of primary qualities resemble their objects, but those of secondary qualities don't [Locke]
In Locke, the primary qualities are also powers [Locke, by Heil]
12. Knowledge Sources / B. Perception / 2. Qualities in Perception / d. Secondary qualities
In my view Locke's 'textures' are groups of corpuscles which are powers (rather than 'having' powers) [Locke, by Alexander,P]
I suspect that Locke did not actually believe colours are 'in the mind' [Locke, by Heil]
Secondary qualities are simply the bare powers of an object [Locke]
12. Knowledge Sources / B. Perception / 4. Sense Data / d. Sense-data problems
Sense-data are dubious abstractions, with none of the plausibility of tables [Quine]
12. Knowledge Sources / B. Perception / 6. Inference in Perception
Molyneux's Question: could a blind man distinguish cube from sphere, if he regained his sight? [Locke]
12. Knowledge Sources / D. Empiricism / 1. Empiricism
All the ideas written on the white paper of the mind can only come from one place - experience [Locke]
Empiricism makes a basic distinction between truths based or not based on facts [Quine]
Quine's empiricism is based on whole theoretical systems, not on single mental events [Quine, by Orenstein]
Empiricism improvements: words for ideas, then sentences, then systems, then no analytic, then naturalism [Quine]
In scientific theories sentences are too brief to be independent vehicles of empirical meaning [Quine]
Our outer beliefs must match experience, and our inner ones must be simple [Quine]
12. Knowledge Sources / D. Empiricism / 2. Associationism
Some ideas connect together naturally, while others connect by chance or custom [Locke]
The constant link between whiteness and things that produce it is the basis of our knowledge [Locke]
Knowledge is just the connection or disagreement of our ideas [Locke]
12. Knowledge Sources / D. Empiricism / 4. Pro-Empiricism
The absolute boundaries of our thought are the ideas we get from senses and the mind [Locke]
Empiricism says evidence rests on the senses, but that insight is derived from science [Quine]
12. Knowledge Sources / D. Empiricism / 5. Empiricism Critique
The second dogma is linking every statement to some determinate observations [Quine, by Yablo]
It is unclear how identity, equality, perfection, God, power and cause derive from experience [Locke, by Dancy,J]
12. Knowledge Sources / E. Direct Knowledge / 2. Intuition
Intuition gives us direct and certain knowledge of what is obvious [Locke]
13. Knowledge Criteria / A. Justification Problems / 1. Justification / b. Need for justification
Believing without a reason may just be love of your own fantasies [Locke]
13. Knowledge Criteria / B. Internal Justification / 5. Coherentism / a. Coherence as justification
Facts beyond immediate experience are assessed by agreement with known truths and observations [Locke]
13. Knowledge Criteria / C. External Justification / 1. External Justification
For Locke knowledge relates to objects, not to propositions [Locke, by Rorty]
13. Knowledge Criteria / C. External Justification / 8. Social Justification
Other men's opinions don't add to our knowledge - even when they are true [Locke]
13. Knowledge Criteria / C. External Justification / 9. Naturalised Epistemology
You can't reduce epistemology to psychology, because that presupposes epistemology [Maund on Quine]
We should abandon a search for justification or foundations, and focus on how knowledge is acquired [Quine, by Davidson]
If we abandon justification and normativity in epistemology, we must also abandon knowledge [Kim on Quine]
Without normativity, naturalized epistemology isn't even about beliefs [Kim on Quine]
Epistemology is a part of psychology, studying how our theories relate to our evidence [Quine]
13. Knowledge Criteria / D. Scepticism / 6. Scepticism Critique
Locke has no patience with scepticism [Locke, by Robinson,H]
13. Knowledge Criteria / E. Relativism / 4. Cultural relativism
To proclaim cultural relativism is to thereby rise above it [Quine, by Newton-Smith]
13. Knowledge Criteria / E. Relativism / 5. Language Relativism
Two things are relative - the background theory, and translating the object theory into the background theory [Quine]
14. Science / A. Basis of Science / 3. Experiment
Science is common sense, with a sophisticated method [Quine]
14. Science / B. Scientific Theories / 1. Scientific Theory
Two theories can be internally consistent and match all the facts, yet be inconsistent with one another [Quine, by Baggini /Fosl]
It seems obvious to prefer the simpler of two theories, on grounds of beauty and convenience [Quine]
There are four suspicious reasons why we prefer simpler theories [Quine]
14. Science / B. Scientific Theories / 3. Instrumentalism
For Quine, theories are instruments used to make predictions about observations [Quine, by O'Grady]
14. Science / B. Scientific Theories / 6. Theory Holism
Statements about the external world face the tribunal of sense experience as a corporate body [Quine]
14. Science / C. Induction / 1. Induction
Induction relies on similar effects following from each cause [Quine]
Induction is just more of the same: animal expectations [Quine]
14. Science / C. Induction / 2. Aims of Induction
More careful inductions gradually lead to the hypothetico-deductive method [Quine]
14. Science / C. Induction / 5. Paradoxes of Induction / a. Grue problem
Grue is a puzzle because the notions of similarity and kind are dubious in science [Quine]
14. Science / D. Explanation / 2. Types of Explanation / k. Explanations by essence
Locke seems to use real essence for scientific explanation, and substratum for the being of a thing [Locke, by Jones,J-E]
To explain qualities, Locke invokes primary and secondary qualities, not real essences [Locke, by Jones,J-E]
Gold is supposed to have a real essence, from whence its detectable properties flow [Locke]
15. Nature of Minds / A. Nature of Mind / 4. Other Minds / c. Knowing other minds
We are satisfied that other men have minds, from their words and actions [Locke]
15. Nature of Minds / A. Nature of Mind / 7. Animal Minds
Unlike humans, animals cannot entertain general ideas [Locke]
15. Nature of Minds / B. Features of Minds / 1. Consciousness / f. Higher-order thought
Consciousness is the perception of what passes in a man's own mind [Locke]
15. Nature of Minds / B. Features of Minds / 2. Unconscious Mind
If we aren't aware that an idea is innate, the concept of innate is meaningless; if we do, all ideas seem innate [Locke]
15. Nature of Minds / B. Features of Minds / 6. Inverted Qualia
There is nothing illogical about inverted qualia [Locke]
The same object might produce violet in one mind and marigold in another [Locke]
15. Nature of Minds / C. Capacities of Minds / 2. Imagination
Locke's view that thoughts are made of ideas asserts the crucial role of imagination [Locke]
15. Nature of Minds / C. Capacities of Minds / 4. Objectification
Every external object or internal idea suggests to us the idea of unity [Locke]
The mind can make a unity out of anything, no matter how diverse [Locke]
15. Nature of Minds / C. Capacities of Minds / 5. Generalisation by mind
The mind creates abstractions by generalising about appearances of objects, ignoring time or place [Locke]
General words represent general ideas, which are abstractions from immediate circumstances [Locke]
15. Nature of Minds / C. Capacities of Minds / 7. Seeing Resemblance
General terms depend on similarities among things [Quine]
To learn yellow by observation, must we be told to look at the colour? [Quine]
Standards of similarity are innate, and the spacing of qualities such as colours can be mapped [Quine]
Similarity is just interchangeability in the cosmic machine [Quine]
15. Nature of Minds / C. Capacities of Minds / 8. Remembering Contiguity
If a man sees a friend die in a room, he associates the pain with the room [Locke]
16. Persons / A. Concept of a Person / 1. Existence of Persons
Locke uses 'self' for a momentary entity, and 'person' for an extended one [Locke, by Martin/Barresi]
A person is intelligent, rational, self-aware, continuous, conscious [Locke]
16. Persons / A. Concept of a Person / 2. Persons as Responsible
Someone mad then sane is two persons, judging by our laws and punishments [Locke]
'Person' is a term used about responsibility, involving law, and happiness and misery [Locke]
16. Persons / B. Nature of the Self / 1. Self and Consciousness
Our personal identity must depend on something we are aware of, namely consciousness [Locke]
My little finger is part of me if I am conscious of it [Locke]
16. Persons / D. Continuity of the Self / 2. Mental Continuity / a. Memory is Self
Personal identity is my perceptions, but not my memory, as I forget too much [Ayer on Locke]
Locke's theory confusingly tries to unite consciousness and memory [Reid on Locke]
Locke mistakes similarity of a memory to its original event for identity [Reid on Locke]
Identity over time involves remembering actions just as they happened [Locke]
Should we punish people who commit crimes in their sleep? [Locke]
16. Persons / D. Continuity of the Self / 2. Mental Continuity / b. Self as mental continuity
For Locke, conscious awareness unifies a person at an instant and over time [Locke, by Martin/Barresi]
If the soul individuates a man, and souls are transferable, then a hog could be a man [Locke]
Identity must be in consciousness not substance, because it seems transferable [Locke]
If someone becomes conscious of Nestor's actions, then he is Nestor [Locke]
If a prince's soul entered a cobbler's body, the person would be the prince (and the man the cobbler) [Locke]
On Judgement Day, no one will be punished for actions they cannot remember [Locke]
Locke sees underlying substance as irrelevant to personal identity [Locke, by Noonan]
16. Persons / D. Continuity of the Self / 2. Mental Continuity / c. Inadequacy of mental continuity
Locke implies that each thought has two thinkers - me, and 'my' substance [Merricks on Locke]
Two persons might have qualitatively identical consciousnesses, so that isn't enough [Kant on Locke]
Locke's move from substance to consciousness is a slippery slope [Butler on Locke]
No two thoughts at different times can be the same, as they have different beginnings [Locke]
Locke confuses the test for personal identity with the thing itself [Reid on Locke]
If consciousness is interrupted, and we forget our past selves, are we still the same thinking thing? [Locke]
If identity is consciousness, could a person move between bodies or fragment into parts? [Reid on Locke]
Locke's memory theory of identity confuses personal identity with the test for it [Reid on Locke]
Butler thought Locke's theory was doomed once he rejected mental substance [Perry on Locke]
16. Persons / E. Rejecting the Self / 1. Self as Indeterminate
Nothing about me is essential [Locke]
16. Persons / F. Free Will / 1. Nature of Free Will
We are free to decide not to follow our desires [Locke]
16. Persons / F. Free Will / 5. Against Free Will
Men are not free to will, because they cannot help willing [Locke]
16. Persons / F. Free Will / 7. Compatibilism
Liberty is a power of agents, so can't be an attribute of wills [Locke]
A man is free insofar as he can act according to his own preferences [Locke]
17. Mind and Body / A. Mind-Body Dualism / 8. Dualism of Mind Critique
For all we know, an omnipotent being might have enabled material beings to think [Locke]
17. Mind and Body / D. Property Dualism / 6. Mysterianism
Thinking without matter and matter that thinks are equally baffling [Locke]
We can't begin to conceive what would produce some particular experience within our minds [Locke]
Thoughts moving bodies, and bodies producing thoughts, are equally unknowable [Locke]
17. Mind and Body / E. Mind as Physical / 3. Eliminativism
Quine expresses the instrumental version of eliminativism [Quine, by Rey]
17. Mind and Body / E. Mind as Physical / 6. Conceptual Dualism
A hallucination can, like an ague, be identified with its host; the ontology is physical, the idiom mental [Quine]
18. Thought / A. Modes of Thought / 8. Human Thought
For Locke, abstract ideas are our main superiority of understanding over animals [Locke, by Berkeley]
18. Thought / C. Content / 2. Ideas
Complex ideas are all resolvable into simple ideas [Locke]
The word 'idea' covers thinking best, for imaginings, concepts, and basic experiences [Locke]
Ideas are the objects of understanding when we think [Locke]
18. Thought / D. Concepts / 2. Origin of Concepts / b. Empirical concepts
All our ideas derive either from sensation, or from inner reflection [Locke]
Simple ideas are produced in us by external things, and they match their appearances [Locke]
18. Thought / D. Concepts / 2. Origin of Concepts / c. Nativist concepts
Innate ideas are nothing, if they are in the mind but we are unaware of them [Locke]
18. Thought / D. Concepts / 5. Concepts and Language / b. Concepts are linguistic
Concepts are language [Quine]
18. Thought / E. Abstraction / 1. Abstract Thought
A species of thing is an abstract idea, and a word is a sign that refers to the idea [Locke]
Apply '-ness' or 'class of' to abstract general terms, to get second-level abstract singular terms [Quine]
19. Language / A. Nature of Meaning / 1. Meaning
It is troublesome nonsense to split statements into a linguistic and a factual component [Quine]
Inculcations of meanings of words rests ultimately on sensory evidence [Quine]
19. Language / A. Nature of Meaning / 2. Meaning as Mental
Words were devised as signs for inner ideas, and their basic meaning is those ideas [Locke]
Words stand for the ideas in the mind of him that uses them [Locke]
19. Language / A. Nature of Meaning / 4. Meaning as Truth-Conditions
If we understand a statement, we know the circumstances of its truth [Quine]
19. Language / A. Nature of Meaning / 7. Meaning Holism / a. Sentence meaning
Taking sentences as the unit of meaning makes useful paraphrasing possible [Quine]
Knowing a word is knowing the meanings of sentences which contain it [Quine]
19. Language / A. Nature of Meaning / 7. Meaning Holism / b. Language holism
There is an attempt to give a verificationist account of meaning, without the error of reducing everything to sensations [Dennett on Quine]
19. Language / A. Nature of Meaning / 8. Synonymy
'Renate' and 'cordate' have identical extensions, but are not synonymous [Quine, by Miller,A]
Single words are strongly synonymous if their interchange preserves truth [Quine]
19. Language / A. Nature of Meaning / 10. Denial of Meanings
Once meaning and reference are separated, meaning ceases to seem important [Quine]
Intensions are creatures of darkness which should be exorcised [Quine]
Meaning is essence divorced from things and wedded to words [Quine]
I do not believe there is some abstract entity called a 'meaning' which we can 'have' [Quine]
The word 'meaning' is only useful when talking about significance or about synonymy [Quine]
19. Language / B. Reference / 1. Reference theories
Quine says there is no matter of fact about reference - it is 'inscrutable' [Quine, by O'Grady]
Reference is inscrutable, because we cannot choose between theories of numbers [Quine, by Orenstein]
19. Language / B. Reference / 3. Direct Reference / c. Social reference
For the correct reference of complex ideas, we can only refer to experts [Locke]
19. Language / C. Assigning Meanings / 2. Semantics
Syntax and semantics are indeterminate, and modern 'semantics' is a bogus subject [Quine, by Lycan]
19. Language / C. Assigning Meanings / 3. Predicates
Quine relates predicates to their objects, by being 'true of' them [Quine, by Davidson]
Projectible predicates can be universalised about the kind to which they refer [Quine]
19. Language / D. Propositions / 2. Abstract Propositions / a. Propositions as sense
A 'proposition' is said to be the timeless cognitive part of the meaning of a sentence [Quine]
19. Language / D. Propositions / 6. Propositions Critique
The problem with propositions is their individuation. When do two sentences express one proposition? [Quine]
It makes no sense to say that two sentences express the same proposition [Quine]
There is no rule for separating the information from other features of sentences [Quine]
We can abandon propositions, and just talk of sentences and equivalence [Quine]
19. Language / E. Analyticity / 1. Analytic Propositions
Analytic statements are either logical truths (all reinterpretations) or they depend on synonymy [Quine]
19. Language / E. Analyticity / 3. Analytic and Synthetic
Without the analytic/synthetic distinction, Carnap's ontology/empirical distinction collapses [Quine]
19. Language / E. Analyticity / 4. Analytic/Synthetic Critique
Did someone ever actually define 'bachelor' as 'unmarried man'? [Quine]
Quine's attack on analyticity undermined linguistic views of necessity, and analytic views of the a priori [Quine, by Boghossian]
Quine attacks the Fregean idea that we can define analyticity through synonyous substitution [Quine, by Thomasson]
The last two parts of 'Two Dogmas' are much the best [Miller,A on Quine]
Erasing the analytic/synthetic distinction got rid of meanings, and saved philosophy of language [Davidson on Quine]
The analytic needs excessively small units of meaning and empirical confirmation [Quine, by Jenkins]
If we try to define analyticity by synonymy, that leads back to analyticity [Quine]
In observation sentences, we could substitute community acceptance for analyticity [Quine]
The distinction between meaning and further information is as vague as the essence/accident distinction [Quine]
Holism in language blurs empirical synthetic and empty analytic sentences [Quine]
I will even consider changing a meaning to save a law; I question the meaning-fact cleavage [Quine]
19. Language / F. Communication / 4. Private Language

Translation is too flimsy a notion to support theories of cultural incommensurability [Quine]
19. Language / F. Communication / 6. Interpreting Language / b. Indeterminate translation
Indeterminacy of translation also implies indeterminacy in interpreting people's mental states [Dennett on Quine]
The firmer the links between sentences and stimuli, the less translations can diverge [Quine]
We can never precisely pin down how to translate the native word 'Gavagai' [Quine]
Stimulus synonymy of 'Gavagai' and 'Rabbit' does not even guarantee they are coextensive [Quine]
Dispositions to speech behaviour, and actual speech, are never enough to fix any one translation [Quine]
You could know the complete behavioural conditions for a foreign language, and still not know their beliefs [Quine]
Translation of our remote past or language could be as problematic as alien languages [Quine]
Indeterminacy translating 'rabbit' depends on translating individuation terms [Quine]
19. Language / F. Communication / 6. Interpreting Language / c. Principle of charity
We should be suspicious of a translation which implies that a people have very strange beliefs [Quine]
Weird translations are always possible, but they improve if we impose our own logic on them [Quine]
The principle of charity only applies to the logical constants [Quine, by Miller,A]

If anyone enjoys the benefits of government (even using a road) they give tacit assent to its laws [Locke]
A politic society is created from a state of nature by a unanimous agreement [Locke]
