2. Reason / C. Styles of Reason / 1. Dialectic
The free dialectic opposition of arguments is an invaluable part of the sceptical method [Kant]
2. Reason / D. Definition / 1. Definitions
Definition rests on synonymy, rather than explaining it [Quine]
2. Reason / D. Definition / 2. Aims of Definition
Definitions exhibit the exhaustive concept of a thing within its boundaries [Kant]
A simplification which is complete constitutes a definition [Kant]
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 / D. Definition / 13. Against Definition
No a priori concept can be defined [Kant]
2. Reason / E. Argument / 2. Transcendental Argument
'Transcendent' is beyond experience, and 'transcendental' is concealed within experience [Kant, by Potter]
Transcendental ideas require unity of the subject, conditions of appearance, and objects of thought [Kant]
Transcendental cognition is that a priori thought which shows how the a priori is applicable or possible [Kant]

2. Reason / F. Fallacies / 1. Fallacy
The Struthionic Fallacy is that of burying one's head in the sand [Quine]
3. Truth / C. Correspondence Truth / 1. Correspondence Truth
We must presuppose that truth is agreement of cognition with its objects [Kant]
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 / 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
Philosophy has no axioms, as it is just rational cognition of concepts [Kant]
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]

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
Logic has precise boundaries, and is the formal rules for all thinking [Kant]
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
Logic gives us the necessary rules which show us how we ought to think [Kant]
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]
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 / 2. Formal Truth
There must be a general content-free account of truth in the rules of logic [Kant]
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
The battle of the antinomies is usually won by the attacker, and lost by any defender [Kant]
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 / 1. Mathematics
Mathematics cannot proceed just by the analysis of concepts [Kant]
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]
Geometry rests on our intuition of space [Kant]
Geometry would just be an idle game without its connection to our intuition [Kant]
Geometrical truth comes from a general schema abstracted from a particular object [Kant, by Burge]
Geometry is not analytic, because a line's being 'straight' is a quality [Kant]
Geometry studies the Euclidean space that dictates how we perceive things [Kant, by Shapiro]
6. Mathematics / A. Nature of Mathematics / 3. Nature of Numbers / a. Numbers
Numbers are formed by addition of units in time [Kant]
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 / 4. Using Numbers / f. Arithmetic
7+5 = 12 is not analytic, because no analysis of 7+5 will reveal the concept of 12 [Kant]
6. Mathematics / A. Nature of Mathematics / 5. The Infinite / c. Potential infinite
Kant only accepts potential infinity, not actual infinity [Kant, by Brown,JR]
6. Mathematics / B. Foundations for Mathematics / 3. Axioms for Geometry
Euclid's could be the only viable geometry, if rejection of the parallel line postulate doesn't lead to a contradiction [Benardete,JA on Kant]
There are four different possible conventional accounts of geometry [Quine]
6. Mathematics / B. Foundations for Mathematics / 4. Axioms for Number / a. Axioms for numbers
Kant suggested that arithmetic has no axioms [Kant, by Shapiro]
Axioms ought to be synthetic a priori propositions [Kant]
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 / 2. Intuition of Mathematics
Kant's intuitions struggle to judge relevance, impossibility and exactness [Kitcher on Kant]
Mathematics can only start from an a priori intuition which is not empirical but pure [Kant]
All necessary mathematical judgements are based on intuitions of space and time [Kant]
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
Maths is a priori, but without its relation to empirical objects it is meaningless [Kant]
Quine blurs the difference between knowledge of arithmetic and of physics [Jenkins on Quine]
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 / 4. Mathematical Empiricism / c. Against mathematical empiricism
Mathematics cannot be empirical because it is necessary, and that has to be a priori [Kant]
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
Kant taught that mathematics is independent of logic, and cannot be grounded in it [Kant, by Hilbert]
If 7+5=12 is analytic, then an infinity of other ways to reach 12 have to be analytic [Kant, by Dancy,J]
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 / 1. Nature of Existence
Saying a thing 'is' adds nothing to it - otherwise if my concept exists, it isn't the same as my concept [Kant]
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 / 6. Criterion for Existence
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 / 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
Kant is read as the phenomena being 'contrained' by the noumenon, or 'free-floating' [Talbot on Kant]
7. Existence / D. Theories of Reality / 4. Anti-realism
Without the subject or the senses, space and time vanish, as their appearances disappear [Kant]
Even the most perfect intuition gets no closer to things in themselves [Kant]
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 / 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]
Categories are necessary, so can't be implanted in us to agree with natural laws [Kant]
Categories are general concepts of objects, which determine the way in which they are experienced [Kant]
7. Existence / E. Categories / 2. Categorisation
Does Kant say the mind imposes categories, or that it restricts us to them? [Rowlands on Kant]
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
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 / 3. Powers as Derived
Dispositions are physical states of mechanism; when known, these replace the old disposition term [Quine]
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
Kant claims causal powers are relational rather than intrinsic [Kant, by Bayne]
8. Modes of Existence / D. Universals / 1. Universals
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
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 a priori concept of objects in general is the ground of experience [Kant]
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]
Objects in themselves are not known to us at all [Kant]
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
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 / B. Unity of Objects / 2. Substance / a. Substance
A substance could exist as a subject, but not as a mere predicate [Kant]
9. Objects / B. Unity of Objects / 2. Substance / d. Substance defined
All appearances need substance, as that which persists through change [Kant]
Substance must exist, as the persisting substratum of the process of change [Kant]
9. Objects / B. Unity of Objects / 2. Substance / e. Substance critique
The substance, once the predicates are removed, remains unknown to us [Kant]
9. Objects / D. Essence of Objects / 9. Essence and Properties
Aristotelian essentialism says a thing has some necessary and some non-necessary properties [Quine]
9. Objects / D. Essence of Objects / 15. Against Essentialism
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
An a priori principle of persistence anticipates all experience [Kant]
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 / 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 / 6. Identity between Objects
Identity of physical objects is just being coextensive [Quine]
9. Objects / F. Identity among Objects / 7. Indiscernible Objects
The Identity of Indiscernibles is true of concepts with identical properties, but not of particulars [Kant, by Jolley]
If we ignore differences between water drops, we still distinguish them by their location [Kant]
We should just identify any items which are indiscernible within a given discourse [Quine]
10. Modality / A. Necessity / 1. Types of Modality
Modalities do not augment our concepts; they express their relation to cognition [Kant]
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 / 7. Natural Necessity
Natural necessity is the unconditioned necessity of appearances [Kant]
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
Is the possible greater than the actual, and the actual greater than the necessary? [Kant]
The analytic mark of possibility is that it does not generate a contradiction [Kant]
That a concept is not self-contradictory does not make what it represents possible [Kant]
A concept is logically possible if non-contradictory (but may not be actually possible) [Kant]
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]
What stays the same in assessing a counterfactual antecedent depends on context [Quine]
Counterfactuals have no place in a strict account of science [Quine]
10. Modality / C. Sources of Modality / 1. Sources of Necessity
Necessity cannot be extracted from an empirical proposition [Kant]
10. Modality / C. Sources of Modality / 4. Necessity from Concepts
Formal experience conditions show what is possible, and general conditions what is necessary [Kant]
10. Modality / D. Knowledge of Modality / 1. A Priori Necessary
Kant thought worldly necessities are revealed by what maths needs to make sense [Kant, by Morris,M]
Necessity is always knowable a priori, and what is known a priori is always necessary [Kant, by Schroeter]
For Kant metaphysics must be necessary, so a priori, so can't be justified by experience [Kant, by Maudlin]
Maths must be a priori because it is necessary, and that cannot be derived from experience [Kant]
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
Knowledge is threefold: apprehension, reproduction by imagination, recognition by concepts [Kant, by Bowie]
'Transcendental' concerns how we know, rather than what we know [Kant]
Knowledge begins with intuitions, moves to concepts, and ends with ideas [Kant]
11. Knowledge Aims / A. Knowledge / 2. Understanding
Kant showed that the understanding (unlike reason) concerns what is finite and conditioned [Kant, by Hegel]
Understanding essentially involves singular elements [Kant, by Burge]
Reason is distinct from understanding, and is the faculty of rules or principles [Kant]
11. Knowledge Aims / A. Knowledge / 4. Belief / a. Beliefs
Opinion is subjectively and objectively insufficient; belief is subjective but not objective; knowledge is both [Kant]
Beliefs can be ascribed to machines [Quine]
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 / 5. Cogito Critique
'I think therefore I am' is an identity, not an inference (as there is no major premise) [Kant]
11. Knowledge Aims / C. Knowing Reality / 2. Phenomenalism
There are possible inhabitants of the moon, but they are just possible experiences [Kant]
We can never translate our whole language of objects into phenomenalism [Quine]
11. Knowledge Aims / C. Knowing Reality / 3. Idealism / a. Idealism
We have no sensual experience of time and space, so they must be 'ideal' [Kant, by Pinkard]
Objects having to be experiencable is not the same as full idealism [Gardner on Kant]
If we disappeared, then all relations of objects, and time and space themselves, disappear too [Kant]
11. Knowledge Aims / C. Knowing Reality / 3. Idealism / b. Transcendental idealism
I admit there are bodies outside us [Kant]
In Kantian idealism, objects fit understanding, not vice versa [Kant, by Feuerbach]
Kant's idealism is a limited idealism based on the viewpoint of empiricism [Kant, by Feuerbach]
For Kant experience is either structured like reality, or generates reality's structure [Kant, by Gardner]
The concepts that make judgeable experiences possible are created spontaneously [Kant, by Pinkard]
'Transcendental' is not beyond experience, but a prerequisite of experience [Kant]
'Transcendental' cognition concerns what can be known a priori of its mode [Kant]
We cannot know things in themselves, but are confined to appearances [Kant]
We have proved that bodies are appearances of the outer senses, not things in themselves [Kant]
Everything we intuit is merely a representation, with no external existence (Transcendental Idealism) [Kant]
11. Knowledge Aims / C. Knowing Reality / 3. Idealism / d. Absolute idealism
Transcendental philosophy is the subject becoming the originator of unified reality [Kant]
12. Knowledge Sources / A. A Priori Knowledge / 1. Nature of the A Priori
Kant's shift of view enables us to see a priority in terms of mental capacity, not truth and propositions [Burge on Kant]
A priori knowledge is limited to objects of possible experience [Kant, by Jolley]
A priori knowledge occurs absolutely independently of all experience [Kant]
One sort of a priori knowledge just analyses given concepts, but another ventures further [Kant]
12. Knowledge Sources / A. A Priori Knowledge / 2. Self-Evidence
Experienceless bodies have space; propertyless bodies have substance; this must be seen a priori [Kant]
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
We are equipped with the a priori intuitions needed for the concept of right [Kant]
12. Knowledge Sources / A. A Priori Knowledge / 4. A Priori as Necessities
Two plus two objects make four objects even if experience is impossible, so Kant is wrong [Russell on Kant]
Propositions involving necessity are a priori, and pure a priori if they only derive from other necessities [Kant]
The apriori is independent of its sources, and marked by necessity and generality [Kant, by Burge]
A priori knowledge is indispensable for the possibility and certainty of experience [Kant]
12. Knowledge Sources / A. A Priori Knowledge / 5. A Priori Synthetic
Seeing that only one parallel can be drawn to a line through a given point is clearly synthetic a priori [Kant, by Benardete,JA]
The categorical imperative is a practical synthetic a priori proposition [Kant]
Kant bases the synthetic a priori on the categories of oneness and manyness [Kant, by Bowie]
Kant showed that we have a priori knowledge which is not purely analytic [Kant, by Russell]
We can think of 7 and 5 without 12, but it is still a contradiction to deny 7+5=12 [Ayer on Kant]
A priori synthetic knowledge is only of appearances, not of things in themselves [Kant]
That a straight line is the shortest is synthetic, as straight does not imply any quantity [Kant]
That force and counter-force are equal is necessary, and a priori synthetic [Kant]
The real problem of pure reason is: how are a priori synthetic judgments possible? [Kant]
That two lines cannot enclose a space is an intuitive a priori synthetic proposition [Kant]
Are a priori concepts necessary as a precondition for something to be an object? [Kant]
7+5=12 is not analytic, because 12 is not contained in 7 or 5 or their combination [Kant]
We possess synthetic a priori knowledge in our principles which anticipate experience [Kant]
12. Knowledge Sources / A. A Priori Knowledge / 6. A Priori from Reason
Reason contains within itself certain underived concepts and principles [Kant]
12. Knowledge Sources / A. A Priori Knowledge / 7. A Priori from Convention
If, as Kant says, arithmetic and logic are contributed by us, they could change if we did [Russell on Kant]
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
No analysis of the sum of seven and five will in itself reveal twelve [Kant]
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 / 9. A Priori from Concepts
For Kant analytic knowledge needs complex concepts, but the a priori can rest on the simple [Coffa on Kant]
A priori intuitions can only concern the objects of our senses [Kant]
With large numbers it is obvious that we could never find the sum by analysing the concepts [Kant]
12. Knowledge Sources / A. A Priori Knowledge / 10. A Priori as Subjective
A priori intuition of objects is only possible by containing the form of my sensibility [Kant]
A priori the understanding can only anticipate possible experiences [Kant]
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 / b. Primary/secondary
We know the shape of a cone from its concept, but we don't know its colour [Kant]
12. Knowledge Sources / B. Perception / 2. Qualities in Perception / d. Secondary qualities
I can make no sense of the red experience being similar to the quality in the object [Kant]
Colours and tastes are not qualities of things, but alterations of the subject [Kant]
12. Knowledge Sources / B. Perception / 2. Qualities in Perception / e. Primary/secondary critique
I count the primary features of things (as well as the secondary ones) as mere appearances [Kant]
12. Knowledge Sources / B. Perception / 3. Representation
I can't intuit a present thing in itself, because the properties can't enter my representations [Kant]
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 / 5. Interpretation
Kant says the cognitive and sensory elements in experience can't be separated [Kant, by Dancy,J]
12. Knowledge Sources / B. Perception / 6. Inference in Perception
Appearances have a 'form', which indicates a relational order [Kant]
12. Knowledge Sources / C. Rationalism / 1. Rationalism
We cannot represent objects unless we combine concepts with intuitions [Kant]
12. Knowledge Sources / D. Empiricism / 1. Empiricism
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
I exist just as an intelligence aware of its faculty for combination [Kant]
Associations and causes cannot explain content, which needs norms of judgement [Kant, by Pinkard]
12. Knowledge Sources / D. Empiricism / 4. Pro-Empiricism
For Kant, our conceptual scheme is disastrous when it reaches beyond experience [Kant, by Fogelin]
Appearance gives truth, as long as it is only used within experience [Kant]
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]
Understanding has no intuitions, and senses no thought, so knowledge needs their unity [Kant]
Sensations are a posteriori, but that they come in degrees is known a priori [Kant]
12. Knowledge Sources / E. Direct Knowledge / 2. Intuition
Kantian intuitions are of particulars, and they give immediate knowledge [Kant, by Shapiro]
Intuition is a representation that depends on the presence of the object [Kant]
13. Knowledge Criteria / A. Justification Problems / 3. Internal or External / b. Pro-externalism
If we knew what we know, we would be astonished [Kant]
13. Knowledge Criteria / B. Internal Justification / 4. Foundationalism / f. Foundationalism critique
A sufficient but general sign of truth cannot possibly be provided [Kant]
13. Knowledge Criteria / B. Internal Justification / 5. Coherentism / a. Coherence as justification
Kant says knowledge is when our representations sufficiently conform to our concepts [Kant, by Critchley]
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 / 1. Scepticism
Kant thought he had refuted scepticism, but his critics say he is a sceptic, for rejecting reality [O'Grady on Kant]
13. Knowledge Criteria / D. Scepticism / 6. Scepticism Critique
Scepticism is the euthanasia of pure reason [Kant]
Scepticism is absurd in maths, where there are no hidden false assertions [Kant]
13. Knowledge Criteria / E. Relativism / 1. Relativism
For Kant, experience is relative to a scheme, but there are no further possible schemes [Kant, by Fogelin]
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 / A. Basis of Science / 6. Falsification
If a proposition implies any false consequences, then it is false [Kant]
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 / j. Explanations by reduction
Science is the reduction of diverse forces and powers to a smaller number that explain them [Kant]
15. Nature of Minds / A. Nature of Mind / 3. Mental Causation
Freedom and natural necessity do not contradict, as they relate to different conditions [Kant]
15. Nature of Minds / B. Features of Minds / 1. Consciousness / f. Higher-order thought
Kant thought that consciousness depends on self-consciousness ('apperception') [Kant, by Crane]
15. Nature of Minds / C. Capacities of Minds / 1. Faculties
Kant's only answer as to how synthetic a priori judgements are possible was that we have a 'faculty'! [Nietzsche on Kant]
Reason has logical and transcendental faculties [Kant]
Judgements which are essentially and strictly universal reveal our faculty of a priori cognition [Kant]
15. Nature of Minds / C. Capacities of Minds / 2. Imagination
We are seldom aware of imagination, but we would have no cognition at all without it [Kant]
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]
16. Persons / A. Concept of a Person / 4. Persons as Agents
Within nature man is unimportant, but as moral person he is above any price [Kant]
16. Persons / B. Nature of the Self / 3. Self as Non-physical
I can express the motion of my body in a single point, but that doesn't mean it is a simple substance [Kant]
16. Persons / B. Nature of the Self / 4. Presupposition of Self
To some extent we must view ourselves as noumena [Kant, by Korsgaard]
Representation would be impossible without the 'I think' that accompanies it [Kant]
16. Persons / B. Nature of the Self / 7. Self and Body / a. Self needs body
We need an account of the self based on rational principles, to avoid materialism [Kant]
16. Persons / C. Self-Awareness / 2. Knowing the Self
Self-knowledge can only be inner sensation, and thus appearance [Kant]
16. Persons / C. Self-Awareness / 3. Limits of Introspection
I have no cognition of myself as I am, but only as I appear to myself [Kant]
16. Persons / D. Continuity of the Self / 2. Mental Continuity / c. Inadequacy of mental continuity
I can only determine my existence in time via external things [Kant]
As balls communicate motion, so substances could communicate consciousness, but not retain identity [Kant]
16. Persons / D. Continuity of the Self / 3. Reference of 'I'
For Kant the self is a purely formal idea, not a substance [Kant, by Lockwood]
16. Persons / D. Continuity of the Self / 7. Self and Thinking
Mental representations would not be mine if they did not belong to a unified self-consciousness [Kant]
16. Persons / F. Free Will / 1. Nature of Free Will
We must assume an absolute causal spontaneity beginning from itself [Kant]
Free will is a kind of causality which works independently of other causes [Kant]
16. Persons / F. Free Will / 2. Sources of Free Will
We shall never be able to comprehend how freedom is possible [Kant]
The manifest will in the world of phenomena has to conform to the laws of nature [Kant]
16. Persons / F. Free Will / 4. For Free Will
We must be free, because we can act against our strongest desires [Kant, by Korsgaard]
If there is a first beginning, there can be other sequences initiated from nothing [Kant]
We cannot conceive of reason as being externally controlled [Kant]
16. Persons / F. Free Will / 5. Against Free Will
Kant made the political will into a pure self-determined "free" will [Kant, by Marx/Engels]
17. Mind and Body / A. Mind-Body Dualism / 1. Dualism
Soul and body connect physically, or by harmony, or by assistance [Kant]
17. Mind and Body / A. Mind-Body Dualism / 8. Dualism of Mind Critique
Our concept of an incorporeal nature is merely negative [Kant]
Neither materialism nor spiritualism can reveal the separate existence of the soul [Kant]
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 / 1. Thought
A pure concept of the understanding can never become an image [Kant]
18. Thought / A. Modes of Thought / 3. Emotions / c. Role of emotions
Kant thought emotions are too random and passive to be part of morality [Kant, by Williams,B]
18. Thought / A. Modes of Thought / 5. Rationality / a. Rationality
Kantian 'intuition' is the bridge between pure reason and its application to sense experiences [Kant, by Friend]
18. Thought / B. Mechanics of Thought / 2. Categories of Understanding
Kant deduced the categories from our judgements, and then as preconditions of experience [Kant, by Houlgate]
Kant says we can describe the categories of thought, but Hegel claims to deduce them [Kant, by Meillassoux]
Categories are concepts that prescribe laws a priori to appearances [Kant]
Four groups of categories of concept: Quantity, Quality, Relation and Modality [Kant]
The categories are objectively valid, because they make experience possible [Kant]
18. Thought / D. Concepts / 1. Concepts / a. Nature of concepts
Thoughts without content are empty, intuitions without concepts are blind [Kant]
Either experience creates concepts, or concepts make experience possible [Kant]
Reason generates no concepts, but frees them from their link to experience in the understanding [Kant]
18. Thought / D. Concepts / 1. Concepts / c. Concepts in psychology
Concepts are rules for combining representations [Kant, by Pinkard]
All human cognition is through concepts [Kant]
18. Thought / D. Concepts / 2. Origin of Concepts / a. Origin of concepts
Some concepts can be made a priori, which are general thoughts of objects, like quantity or cause [Kant]
18. Thought / D. Concepts / 4. Structure of Concepts / b. Analysis of concepts
Kant implies that concepts have analysable parts [Kant, by Shapiro]
18. Thought / D. Concepts / 5. Concepts and Language / b. Concepts are linguistic
Concepts are language [Quine]
18. Thought / E. Abstraction / 1. Abstract Thought
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 / 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 / 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
Non-subject/predicate tautologies won't fit Kant's definition of analyticity [Shapiro on Kant]
How can bachelor 'contain' unmarried man? Are all analytic truths in subject-predicate form? [Miller,A on Kant]
Analytic judgements say clearly what was in the concept of the subject [Kant]
Analytic judgement rests on contradiction, since the predicate cannot be denied of the subject [Kant]
If the predicate is contained in the subject of a judgement, it is analytic; otherwise synthetic [Kant]
Analytic judgements clarify, by analysing the subject into its component predicates [Kant]
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 / 5. Pragmatics / a. Contextual meaning
A good way of explaining an expression is saying what conditions make its contexts true [Quine]
19. Language / F. Communication / 6. Interpreting Language / a. Translation
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]
20. Action / B. Preliminaries of Action / 2. Willed Action / a. Will to Act
Can pure reason determine the will, or are empirical conditions relevant? [Kant]
The will is the faculty of purposes, which guide desires according to principles [Kant]
20. Action / C. Motives for Action / 3. Acting on Reason / a. Practical reason
General rules of action also need a judgement about when to apply them [Kant]
The sole objects of practical reason are the good and the evil [Kant]
21. Aesthetics / A. Aesthetic Experience / 1. Aesthetics
Kant gave form and status to aesthetics, and Hegel gave it content [Kant, by Scruton]
21. Aesthetics / A. Aesthetic Experience / 2. Aesthetic Attitude
The aesthetic attitude is a matter of disinterestedness [Kant, by Wollheim]
Only rational beings can experience beauty [Kant, by Scruton]
It is hard to see why we would have developed Kant's 'disinterested' aesthetic attitude [Cochrane on Kant]
21. Aesthetics / A. Aesthetic Experience / 3. Taste
With respect to the senses, taste is an entirely personal matter [Kant]
When we judge beauty, it isn't just personal; we judge on behalf of everybody [Kant]
Saying everyone has their own taste destroys the very idea of taste [Kant]
21. Aesthetics / A. Aesthetic Experience / 4. Beauty
Kant thinks beauty ignores its objects, because it is only 'form' engaging with mind [Cochrane on Kant]
The beautiful is not conceptualised as moral, but it symbolises or resembles goodness [Kant, by Murdoch]
Kant saw beauty as a sort of disinterested pleasure, which has become separate from the good [Kant, by Taylor,C]
Beauty is only judged in pure contemplation, and not with something else at stake [Kant]
21. Aesthetics / A. Aesthetic Experience / 6. The Sublime
The mathematical sublime is immeasurable greatness; the dynamical sublime is overpowering [Kant, by Pinkard]
The sublime is a moral experience [Kant, by Gardner]
21. Aesthetics / C. Artistic Issues / 5. Objectivism in Art
Aesthetic values are not objectively valid, but we must treat them as if they are [Kant, by Scruton]
The judgement of beauty is not cognitive, but relates, via imagination, to pleasurable feelings [Kant]
22. Metaethics / A. Ethics Foundations / 1. Nature of Ethics / a. Preconditions for ethics

The categorical imperative says nothing about what our activities and ends should be [MacIntyre on Kant]
Only human reason can confer value on our choices [Kant, by Korsgaard]
22. Metaethics / A. Ethics Foundations / 2. Source of Ethics / e. Human nature
Kant thought human nature was pure hedonism, so virtue is only possible via the categorical imperative [Foot on Kant]
22. Metaethics / A. Ethics Foundations / 2. Source of Ethics / h. Expressivism
Moral principles do not involve feelings [Kant]
People cannot come to morality through feeling, because morality must not be sensuous [Kant]

We must only value what others find acceptable [Kant, by Korsgaard]
22. Metaethics / B. Value / 1. Nature of Value / a. Nature of value
Kant focuses exclusively on human values, and neglects cultural and personal values [Kekes on Kant]
Altruistic values concern other persons, and ceremonial values concern practices [Quine]
22. Metaethics / B. Value / 1. Nature of Value / b. Fact and value
We cannot derive moral laws from experience, as it is the mother of illusion [Kant]
22. Metaethics / B. Value / 1. Nature of Value / d. Subjective value
Our rational choices confer value, arising from the sense that we ourselves are important [Kant, by Korsgaard]
Values are created by human choices, and are not some intrinsic quality, out there [Kant, by Berlin]
22. Metaethics / B. Value / 1. Nature of Value / f. Ultimate value
Kant may rate two things as finally valuable: having a good will, and deserving happiness [Orsi on Kant]
An autonomous agent has dignity [Würde], which has absolute worth [Kant, by Pinkard]
The good will is unconditionally good, because it is the only possible source of value [Kant, by Korsgaard]
Good or evil cannot be a thing, but only a maxim of action, making the person good or evil [Kant]
What is contemplated must have a higher value than contemplation [Kant, by Korsgaard]
Only a good will can give man's being, and hence the world, a final purpose [Kant]
The love of man is required in order to present the world as a beautiful and perfect moral whole [Kant]
All morality directs the will to love of others' ends, and respect for others' rights [Kant]
22. Metaethics / B. Value / 2. Values / a. Normativity
We only understand what exists, and can find no sign of what ought to be in nature [Kant]
22. Metaethics / B. Value / 2. Values / f. Altruism
We may claim noble motives, but we cannot penetrate our secret impulses [Kant]
Reverence is awareness of a value which demolishes my self-love [Kant]
22. Metaethics / B. Value / 2. Values / g. Love
The duty of love is to makes the ends of others one's own [Kant]
Love seems to diminish with distance from oneself [Quine]
22. Metaethics / C. The Good / 1. Goodness / g. Consequentialism
A good will is not good because of what it achieves [Kant]
The good of an action is in the mind of the doer, not the consequences [Kant]
Morality involves duty and respect for law, not love of the outcome [Kant]
22. Metaethics / C. The Good / 2. Happiness / a. Nature of happiness
Our happiness is all that matters, not as a sensation, but as satisfaction with our whole existence [Kant]
Happiness is the condition of a rational being for whom everything goes as they wish [Kant]
22. Metaethics / C. The Good / 2. Happiness / c. Value of happiness
Morality is not about making ourselves happy, but about being worthy of happiness [Kant]
Duty does not aim at an end, but gives rise to universal happiness as aim of the will [Kant]
23. Ethics / B. Contract Ethics / 2. Golden Rule
The 'golden rule' cannot be a universal law as it implies no duties [Kant]
23. Ethics / B. Contract Ethics / 3. Promise Keeping
If lies were ever acceptable, with would undermine all duties based on contract [Kant]
23. Ethics / C. Virtue Theory / 1. Virtue Theory / a. Nature of virtue
Virtue lets a rational being make universal law, and share in the kingdom of ends [Kant]
The highest worth for human beings lies in dispositions, not just actions [Kant]
Virtue is the supreme state of our pursuit of happiness, and so is supreme good [Kant]
A duty of virtue is a duty which is also an end [Kant]
Virtue is strong maxims for duty [Kant]
The supreme principle of virtue is to find universal laws for ends [Kant]
23. Ethics / C. Virtue Theory / 1. Virtue Theory / d. Virtue theory critique
Kant thinks virtue becomes passive, and hence morally unaccountable [Kant, by Annas]
23. Ethics / C. Virtue Theory / 2. Elements of Virtue Theory / c. Motivation for virtue
Moral law is holy, and the best we can do is achieve virtue through respect for the law [Kant]
We are obliged to show the social virtues, but at least they make a virtuous disposition fashionable [Kant]
23. Ethics / C. Virtue Theory / 2. Elements of Virtue Theory / d. Teaching virtue
If virtue becomes a habit, that is a loss of the freedom needed for adopting maxims [Kant]
23. Ethics / C. Virtue Theory / 2. Elements of Virtue Theory / f. The Mean
How do we distinguish a mean? The extremes can involve quite different maxims [Kant]
If virtue is the mean between vices, then virtue is just the vanishing of vice [Kant]
23. Ethics / C. Virtue Theory / 2. Elements of Virtue Theory / j. Unity of virtue
There is one principle of virtues; the virtues are distinguished by their objects [Kant]
23. Ethics / C. Virtue Theory / 3. Virtues / f. Compassion
Generosity and pity are vices, because they falsely imply one person's superiority to another [Kant, by Berlin]
23. Ethics / C. Virtue Theory / 3. Virtues / h. Respect
Kantian respect is for humanity and reason (not from love or sympathy or solidarity) [Kant, by Sandel]
We can love without respect, and show respect without love [Kant]
Respect is limiting our self-esteem by attending to the human dignity of other persons [Kant]
Disrespect is using a person as a mere means to my own ends [Kant]
Respect is purely negative (of not exalting oneself over others), and is thus a duty of Right [Kant]
Love urges us to get closer to people, but respect to keep our distance [Kant]
We must respect the humanity even in a vicious criminal [Kant]
23. Ethics / D. Deontological Ethics / 1. Deontology
If 'maxims' are deeper underlying intentions, Kant can be read as a virtue theorist [Kant, by Statman]
We can ask how rational goodness is, but also why is rationality good [Putnam on Kant]
Kant follows Rousseau in defining freedom and morality in terms of each other [Taylor,C on Kant]
The only purely good thing is a good will [Kant]
The will is good if its universalised maxim is never in conflict with itself [Kant]
Other causes can produce nice results, so morality must consist in the law, found only in rational beings [Kant]
It is basic that moral actions must be done from duty [Kant]
23. Ethics / D. Deontological Ethics / 2. Duty
Telling the truth from duty is quite different from doing so to avoid inconvenience [Kant]
There are no imperatives for a holy will, as the will is in harmony with moral law [Kant]
It can't be a duty to strive after the impossible [Kant]

Kant has to attribute high moral worth to some deeply unattractive human lives [Kant, by Graham]
Kantian duty seems to imply conformism with authority [MacIntyre on Kant]
The law will protect you if you tell a truth which results in murder [Kant]
A categorical imperative sees an action as necessary purely for its own sake [Kant]
23. Ethics / D. Deontological Ethics / 3. Universalisability
Almost any precept can be consistently universalized [MacIntyre on Kant]
No one would lend money unless a universal law made it secure, even after death [Kant]
Universality determines the will, and hence extends self-love into altruism [Kant]
23. Ethics / D. Deontological Ethics / 4. Categorical Imperative
The intuition behind the categorical imperative is that one ought not to make an exception of oneself [Kant, by Finlayson]
Universalising a maxim needs to first stipulate the right description for the action [Anscombe on Kant]
The categorical imperative will not suggest maxims suitable for testing [MacIntyre on Kant]
I can universalize a selfish maxim, if it is expressed in a way that only applies to me [MacIntyre on Kant]

Moral blame is based on reason, since a reason is a cause which should have been followed [Kant]
Moral laws are commands, which must involve promises and threats, which only God could provide [Kant]
For Kant, even a person who lacks all sympathy for others still has a motive for benevolence [Kant, by Hursthouse]
If we are required to give moral thought the highest priority, this gives morality no content [Williams,B on Kant]
If Kant lives by self-administered laws, this is as feeble as self-administered punishments [Kierkegaard on Kant]

The function of reason is to produce a good will [Kant]
Our inclinations are not innately desirable; in fact most rational beings would like to be rid of them [Kant]
Actions where people spread happiness because they enjoy it have no genuine moral worth [Kant]
A holy will is incapable of any maxims which conflict with the moral law [Kant]
Reason cannot solve the problem of why a law should motivate the will [Kant]
The will's motive is the absolute law itself, and moral feeling is receptivity to law [Kant]
23. Ethics / F. Existentialism / 5. Existence-Essence
For Kant, essence is mental and a mere idea, and existence is the senses and mere appearance [Kant, by Feuerbach]
24. Political Theory / A. Basis of a State / 1. A People / a. Human distinctiveness
Humans are distinguished from animals by their capacity to set themselves any sort of end [Kant]
Man is both social, and unsociable [Kant]

Kant made the social contract international and cosmopolitan [Kant, by Oksala]
24. Political Theory / B. Nature of a State / 2. State Legitimacy / d. General will
A law is unjust if the whole people could not possibly agree to it [Kant]

An obvious idea is a constitution based on maximum mutual freedom for citizens [Kant]
Our aim is a constitution which combines maximum freedom with strong restraint [Kant]

25. Social Practice / A. Freedoms / 6. Political freedom
The existence of reason depends on the freedom of citizens to agree, doubt and veto ideas [Kant]
25. Social Practice / B. Equalities / 3. Legal equality

25. Social Practice / E. Policies / 2. Religion in Society
The church has a political role, by offering a supreme power over people [Kant]
25. Social Practice / F. Life Issues / 4. Suicide
The maxim for suicide is committed to the value of life, and is thus contradictory [Kant]
A permanent natural order could not universalise a rule permitting suicide [Kant]

Animals are dangerous and nourishing, and can't form contracts of justice [Hermarchus, by Sedley]
Non-rational beings only have a relative value, as means rather than as ends [Kant]
Men can only have duties to those who qualify as persons [Kant]
Cruelty to animals is bad because it dulls our empathy for pain in humans [Kant]
26. Natural Theory / A. Speculations on Nature / 1. Nature
Kant's nature is just a system of necessary laws [Bowie on Kant]
Kant identifies nature with the scientific picture of it as the realm of law [Kant, by McDowell]
The Critique of Judgement aims for a principle that unities humanity and nature [Kant, by Bowie]
26. Natural Theory / A. Speculations on Nature / 2. Natural Purpose / b. Limited purposes
Reason must assume as necessary that everything in a living organism has a proportionate purpose [Kant]
Without men creation would be in vain, and without final purpose [Kant]
26. Natural Theory / A. Speculations on Nature / 7. Later Matter Theories / c. Matter as extension
Extension and impenetrability together make the concept of matter [Kant]
26. Natural Theory / B. Natural Kinds / 1. Natural Kinds
Quine probably regrets natural kinds now being treated as essences [Quine, by Dennett]
If similarity has no degrees, kinds cannot be contained within one another [Quine]
Comparative similarity allows the kind 'colored' to contain the kind 'red' [Quine]
26. Natural Theory / B. Natural Kinds / 3. Knowing Kinds
You can't base kinds just on resemblance, because chains of resemblance are a muddle [Quine]
26. Natural Theory / C. Causation / 8. Particular Causation / b. Causal relata
A ball denting a pillow seems like simultaneous cause and effect, though time identifies which is cause [Kant]
Causal relata are individuated by coarse spacetime regions [Quine, by Schaffer,J]
26. Natural Theory / C. Causation / 9. General Causation / a. Constant conjunction
Appearances give rules of what usually happens, but cause involves necessity [Kant]
26. Natural Theory / C. Causation / 9. General Causation / b. Nomological causation
The concept of causality entails laws; random causality is a contradiction [Kant, by Korsgaard]
We judge causation by relating events together by some law of nature [Kant, by Mares]
Experience is only possible because we subject appearances to causal laws [Kant]
26. Natural Theory / C. Causation / 9. General Causation / d. Causal necessity
Causation obviously involves necessity, so it cannot just be frequent association [Kant]
26. Natural Theory / D. Laws of Nature / 4. Regularities / a. Regularity theory
It is hard to see how regularities could be explained [Quine]
26. Natural Theory / D. Laws of Nature / 8. Scientific Essentialism / b. Scientific necessity
For Kant the laws must be necessary, because contingency would destroy representation [Kant, by Meillassoux]
Kant fails to prove the necessity of laws, because his reasoning about chance is over-ambitious [Meillassoux on Kant]
26. Natural Theory / D. Laws of Nature / 8. Scientific Essentialism / e. Anti scientific essentialism
Essence gives an illusion of understanding [Quine, by Almog]
We can't say 'necessarily if x is in water then x dissolves' if we can't quantify modally [Quine]
27. Natural Reality / C. Space / 2. Space
Space must have three dimensions, because only three lines can meet at right angles [Kant]
We can't learn of space through experience; experience of space needs its representation [Kant]
Space is an a priori necessary basic intuition, as we cannot imagine its absence [Kant]
27. Natural Reality / C. Space / 3. Points in Space
The concept of a 'point' makes no sense without the idea of absolute position [Quine]
27. Natural Reality / D. Time / 1. Nature of Time / a. Absolute time
If all empirical sensation of bodies is removed, space and time are still left [Kant]
If space and time exist absolutely, we must assume the existence of two pointless non-entities [Kant]
27. Natural Reality / D. Time / 1. Nature of Time / c. Idealist time
One can never imagine appearances without time, so it is given a priori [Kant]
27. Natural Reality / D. Time / 2. Passage of Time / a. Experience of time
That times cannot be simultaneous is synthetic, so it is known by intuition, not analysis [Kant]
The three modes of time are persistence, succession and simultaneity [Kant]
27. Natural Reality / D. Time / 2. Passage of Time / b. Rate of time
If time involved succession, we must think of another time in which succession occurs [Kant]
27. Natural Reality / D. Time / 2. Passage of Time / f. Tenseless (B) series
Quine holds time to be 'space-like': past objects are as real as spatially remote ones [Quine, by Sider]
28. God / A. Divine Nature / 6. Divine Morality / b. Euthyphro question
We judge God to be good by a priori standards of moral perfection [Kant]
We don't accept duties as coming from God, but assume they are divine because they are duties [Kant]
We can only know we should obey God if we already have moral standards for judging God [Kant, by MacIntyre]
Obligation does not rest on the existence of God, but on the autonomy of reason [Kant]
28. God / B. Proving God / 1. Proof of God
Only three proofs of God: the physico-theological (evidence), the cosmological (existence), the ontological (a priori) [Kant]
28. God / B. Proving God / 2. Proofs of Reason / b. Ontological Proof critique
If 'this exists' is analytic, either the thing is a thought, or you have presupposed its existence [Kant]
If an existential proposition is synthetic, you must be able to cancel its predicate without contradiction [Kant]
Being is not a real predicate, that adds something to a concept [Kant]
You add nothing to the concept of God or coins if you say they exist [Kant]
Existence is merely derived from the word 'is' (rather than being a predicate) [Kant, by Orenstein]
Modern logic says (with Kant) that existence is not a predicate, because it has been reclassified as a quantifier [Benardete,JA on Kant]
Kant never denied that 'exist' could be a predicate - only that it didn't enlarge concepts [Kant, by Fitting/Mendelsohn]
Is "This thing exists" analytic or synthetic? [Kant]
28. God / B. Proving God / 2. Proofs of Reason / c. Moral Argument
God is not proved by reason, but is a postulate of moral thinking [Kant, by Davies,B]
We have to postulate something outside nature which makes happiness coincide with morality [Kant]
Belief in justice requires belief in a place for justice (heaven), a time (eternity), and a cause (God) [Kant, by PG]
28. God / B. Proving God / 3. Proofs of Evidence / a. Cosmological Proof
If you prove God cosmologically, by a regress in the sequences of causes, you can't abandon causes at the end [Kant]
To know if this world must have been created by God, we would need to know all other possible worlds [Kant]
28. God / B. Proving God / 3. Proofs of Evidence / c. Teleological Proof critique
Using God to explain nature is referring to something inconceivable to explain what is in front of you [Kant]
