2. Reason / A. Nature of Reason / 7. Status of Reason
Opposition to reason is mad [Locke]
2. Reason / B. Laws of Thought / 6. Ockham's Razor
What matters is not how many entities we postulate, but how many kinds of entities [Armstrong, by Mellor/Oliver]
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 / F. Fallacies / 7. Ad Hominem
Ad Hominem: press a man with the consequences of his own principle [Locke]

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 / B. Truthmakers / 4. Truthmaker Necessitarianism
Truth-making can't be entailment, because truthmakers are portions of reality [Armstrong]
Armstrong says truthmakers necessitate their truth, where 'necessitate' is a primitive relation [Armstrong, by MacBride]
3. Truth / B. Truthmakers / 6. Making Negative Truths
Negative existentials have 'totality facts' as truthmakers [Armstrong, by Lewis]
Negative truths have as truthmakers all states of affairs relevant to the truth [Armstrong]
The nature of arctic animals is truthmaker for the absence of penguins there [Armstrong]
3. Truth / B. Truthmakers / 7. Making Modal Truths
In mathematics, truthmakers are possible instantiations of structures [Armstrong]
One truthmaker will do for a contingent truth and for its contradictory [Armstrong]
The truthmakers for possible unicorns are the elements in their combination [Armstrong]
What is the truthmaker for 'it is possible that there could have been nothing'? [Armstrong]
3. Truth / B. Truthmakers / 8. Making General Truths
Necessitating general truthmakers must also specify their limits [Armstrong]
3. Truth / C. Correspondence Truth / 1. Correspondence Truth
Correspondence may be one-many or many one, as when either p or q make 'p or q' true [Armstrong]
4. Formal Logic / A. Syllogistic Logic / 2. Syllogistic Logic
Syllogisms are verbal fencing, not discovery [Locke]
Many people can reason well, yet can't make a syllogism [Locke]
4. Formal Logic / D. Modal Logic ML / 3. Modal Logic Systems / g. System S4
If what is actual might have been impossible, we need S4 modal logic [Armstrong, by Lewis]
4. Formal Logic / F. Set Theory ST / 1. Set Theory
The set theory brackets { } assert that the member is a unit [Armstrong]
4. Formal Logic / F. Set Theory ST / 3. Types of Set / b. Empty (Null) Set
For 'there is a class with no members' we don't need the null set as truthmaker [Armstrong]
5. Theory of Logic / C. Ontology of Logic / 3. If-Thenism
Mathematical proofs work, irrespective of whether the objects exist [Locke]
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 / 4. Using Numbers / a. Units
Classes have cardinalities, so their members must all be treated as units [Armstrong]
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 / 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 / 4. Mathematical Empiricism / a. Mathematical empiricism
Every simple idea we ever have brings the idea of unity along with it [Locke]
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]
7. Existence / C. Structure of Existence / 6. Fundamentals / d. Logical atoms
Comparisons boil down to simple elements of sensation or reflection [Locke]
Logical atomism builds on the simple properties, but are they the only possible properties? [Armstrong]
7. Existence / D. Theories of Reality / 2. Realism
God assures me of the existence of external things [Locke]
7. Existence / D. Theories of Reality / 3. Reality
Some think of reality as made of things; I prefer facts or states of affairs [Armstrong]
7. Existence / D. Theories of Reality / 5. Naturalism
'Naturalism' says only the world of space-time exists [Armstrong]
7. Existence / D. Theories of Reality / 7. Fictionalism
Without modality, Armstrong falls back on fictionalism to support counterfactual laws [Bird on Armstrong]
7. Existence / D. Theories of Reality / 8. Facts / b. Types of fact
Negative facts are supervenient on positive facts, suggesting they are positive facts [Armstrong]
7. Existence / D. Theories of Reality / 9. States of Affairs
Truthmaking needs states of affairs, to unite particulars with tropes or universals. [Armstrong]
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 / 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 / 5. Category Anti-Realism
There are no gaps in the continuum of nature, and everything has something closely resembling it [Locke]
8. Modes of Existence / A. Relations / 4. Formal Relations / a. Types of relation
Nothing is genuinely related to itself [Armstrong]
8. Modes of Existence / B. Properties / 1. Nature of Properties
Properties are universals, which are always instantiated [Armstrong, by Heil]
All instances of some property are strictly identical [Armstrong]
Properties are contingently existing beings with multiple locations in space and time [Armstrong, by Lewis]
8. Modes of Existence / B. Properties / 2. Need for Properties
Without properties we would be unable to express the laws of nature [Armstrong]
We need properties, as minimal truthmakers for the truths about objects [Armstrong]
8. Modes of Existence / B. Properties / 3. Types of Properties
The determinates of a determinable must be incompatible with each other [Armstrong]
Length is a 'determinable' property, and one mile is one its 'determinates' [Armstrong]
8. Modes of Existence / B. Properties / 6. Categorical Properties
Even if all properties are categorical, they may be denoted by dispositional predicates [Armstrong, by Bird]
Armstrong holds that all basic properties are categorical [Armstrong, by Ellis]
8. Modes of Existence / B. Properties / 10. Properties as Predicates
Whether we apply 'cold' or 'hot' to an object is quite separate from its change of temperature [Armstrong]
To the claim that every predicate has a property, start by eliminating failure of application of predicate [Armstrong]
8. Modes of Existence / B. Properties / 13. Tropes / a. Nature of tropes
Tropes fall into classes, because exact similarity is symmetrical and transitive [Armstrong]
One moderate nominalist view says that properties and relations exist, but they are particulars [Armstrong]
If tropes are non-transferable, then they necessarily belong to their particular substance [Armstrong]
8. Modes of Existence / B. Properties / 13. Tropes / b. Critique of tropes
Trope theory needs extra commitments, to symmetry and non-transitivity, unless resemblance is exact [Armstrong]
If properties and relations are particulars, there is still the problem of how to classify and group them [Armstrong]
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]
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 / 5. Powers and Properties
Properties are not powers - they just have powers [Armstrong]
8. Modes of Existence / C. Powers and Dispositions / 6. Dispositions / a. Dispositions
To be realists about dispositions, we can only discuss them through their categorical basis [Armstrong]
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]
Actualism means that ontology cannot contain what is merely physically possible [Armstrong]
Dispositions exist, but their truth-makers are actual or categorical properties [Armstrong]
If everything is powers there is a vicious regress, as powers are defined by more powers [Armstrong]
Powers must result in some non-powers, or there would only be potential without result [Armstrong]
How does the power of gravity know the distance it acts over? [Armstrong]
8. Modes of Existence / D. Universals / 1. Universals
Universals are just the repeatable features of a world [Armstrong]
Locke, Berkeley and Hume did no serious thinking about universals [Robinson,H on Locke]
Particulars and properties are distinguishable, but too close to speak of a relation [Armstrong]
Should we decide which universals exist a priori (through words), or a posteriori (through science)? [Armstrong]
8. Modes of Existence / D. Universals / 2. Need for Universals
The problem of universals is how many particulars can all be of the same 'type' [Armstrong]
Realist regularity theories of laws need universals, to pick out the same phenomena [Armstrong]
Universals are required to give a satisfactory account of the laws of nature [Armstrong]
Universals explain resemblance and causal power [Armstrong, by Oliver]
8. Modes of Existence / D. Universals / 3. Instantiated Universals
Universals are abstractions from states of affairs [Armstrong]
Past, present and future must be equally real if universals are instantiated [Armstrong]
Universals are abstractions from their particular instances [Armstrong, by Lewis]
8. Modes of Existence / D. Universals / 4. Uninstantiated Universals
It is claimed that some universals are not exemplified by any particular, so must exist separately [Armstrong]
8. Modes of Existence / D. Universals / 6. Platonic Forms / c. Self-predication
Most thinkers now reject self-predication (whiteness is NOT white) so there is no Third Man problem [Armstrong]
8. Modes of Existence / E. Nominalism / 1. Nominalism / a. Nominalism
Refusal to explain why different tokens are of the same type is to be an ostrich [Armstrong]
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]
8. Modes of Existence / E. Nominalism / 1. Nominalism / c. Nominalism about abstracta
Deniers of properties and relations rely on either predicates or on classes [Armstrong]
8. Modes of Existence / E. Nominalism / 2. Resemblance Nominalism
'Resemblance Nominalism' finds that in practice the construction of resemblance classes is hard [Armstrong]
Resemblances must be in certain 'respects', and they seem awfully like properties [Armstrong]
'Resemblance Nominalism' says properties are resemblances between classes of particulars [Armstrong]
8. Modes of Existence / E. Nominalism / 3. Predicate Nominalism
It doesn't follow that because there is a predicate there must therefore exist a property [Armstrong]
Change of temperature in objects is quite independent of the predicates 'hot' and 'cold' [Armstrong]
We want to know what constituents of objects are grounds for the application of predicates [Armstrong]
'Predicate Nominalism' says that a 'universal' property is just a predicate applied to lots of things [Armstrong]
8. Modes of Existence / E. Nominalism / 4. Concept Nominalism
Concept and predicate nominalism miss out some predicates, and may be viciously regressive [Armstrong]
'Concept Nominalism' says a 'universal' property is just a mental concept applied to lots of things [Armstrong]
8. Modes of Existence / E. Nominalism / 5. Class Nominalism
In most sets there is no property common to all the members [Armstrong]
'Class Nominalism' may explain properties if we stick to 'natural' sets, and ignore random ones [Armstrong]
'Class Nominalism' says that properties or kinds are merely membership of a set (e.g. of white things) [Armstrong]
'Class Nominalism' cannot explain co-extensive properties, or sets with random members [Armstrong]
The class of similar things is much too big a truthmaker for the feature of a particular [Armstrong]
8. Modes of Existence / E. Nominalism / 6. Mereological Nominalism
'Mereological Nominalism' sees whiteness as a huge white object consisting of all the white things [Armstrong]
'Mereological Nominalism' may work for whiteness, but it doesn't seem to work for squareness [Armstrong]
9. Objects / A. Existence of Objects / 1. Physical Objects
Bodies distinctively have cohesion of parts, and power to communicate motion [Locke]
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]
9. Objects / A. Existence of Objects / 5. Individuation / b. Individuation by properties
It is likely that particulars can be individuated by unique conjunctions of properties [Armstrong]
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]
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]
Essences might support Resemblance Nominalism, but they are too coarse and ill-defined [Armstrong]
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 / 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
When entities contain entities, or overlap with them, there is 'partial' identity [Armstrong]
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 / 4. Type Identity
The type-token distinction is the universal-particular distinction [Armstrong, by Hodes]
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]
A thing's self-identity can't be a universal, since we can know it a priori [Armstrong, by Oliver]
The identity of a thing with itself can be ruled out as a pseudo-property [Armstrong]
10. Modality / B. Possibility / 1. Possibility
All possibilities are recombinations of properties in the actual world [Armstrong, by Lewis]
10. Modality / B. Possibility / 5. Contingency
The necessary/contingent distinction may need to recognise possibilities as real [Armstrong]
10. Modality / C. Sources of Modality / 1. Sources of Necessity
The truth-maker for a truth must necessitate that truth [Armstrong]
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 / E. Possible worlds / 1. Possible Worlds / d. Possible worlds actualism
The best version of reductionist actualism around is Armstrong's combinatorial account [Armstrong, by Read]
10. Modality / E. Possible worlds / 1. Possible Worlds / e. Against possible worlds
Possible worlds don't fix necessities; intrinsic necessities imply the extension in worlds [Armstrong]
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 / d. Cause of beliefs
When two ideas agree in my mind, I cannot refuse to see and know it [Locke]
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]
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 / 10. A Priori as Subjective
The mind cannot produce simple ideas [Locke]
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]
Armstrong suggests secondary qualities are blurred primary qualities [Armstrong, by Robinson,H]
Secondary qualities are microscopic primary qualities of physical things [Armstrong]
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 / B. Perception / 7. Causal Perception
Maybe experience is not essential to perception, but only to the causing of beliefs [Armstrong, by Scruton]
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]
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]
12. Knowledge Sources / D. Empiricism / 5. Empiricism Critique
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]
Externalism says knowledge involves a natural relation between the belief state and what makes it true [Armstrong]
13. Knowledge Criteria / C. External Justification / 7. Testimony
The reliability of witnesses depends on whether they benefit from their observations [Laplace, by Hacking]
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 / D. Scepticism / 6. Scepticism Critique
Locke has no patience with scepticism [Locke, by Robinson,H]
14. Science / C. Induction / 3. Limits of Induction
Induction aims at 'all Fs', but abduction aims at hidden or theoretical entities [Armstrong]
14. Science / C. Induction / 5. Paradoxes of Induction / a. Grue problem
Science suggests that the predicate 'grue' is not a genuine single universal [Armstrong]
Unlike 'green', the 'grue' predicate involves a time and a change [Armstrong]
14. Science / C. Induction / 5. Paradoxes of Induction / b. Raven paradox
The raven paradox has three disjuncts, confirmed by confirming any one of them [Armstrong]
14. Science / D. Explanation / 2. Types of Explanation / a. Types of explanation
A good reason for something (the smoke) is not an explanation of it (the fire) [Armstrong]
14. Science / D. Explanation / 2. Types of Explanation / e. Lawlike explanations
To explain observations by a regular law is to explain the observations by the observations [Armstrong]
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]
14. Science / D. Explanation / 3. Best Explanation / a. Best explanation
Best explanations explain the most by means of the least [Armstrong]
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 / b. Essence of consciousness
Consciousness and experience of qualities are not the same [Armstrong]
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
