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]
We can accept criteria of distinctness and persistence, without making the counterfactual claims [Mackie,P on Wiggins]

9. Objects / A. Existence of Objects / 5. Individuation / e. Individuation by kind
A sortal essence is a thing's principle of individuation [Wiggins, by Mackie,P]
Wiggins's sortal essentialism rests on a thing's principle of individuation [Wiggins, by Mackie,P]
The evening star is the same planet but not the same star as the morning star, since it is not a star [Wiggins]
'Sortalism' says parts only compose a whole if it falls under a sort or kind [Wiggins, by Hossack]
Identity a=b is only possible with some concept to give persistence and existence conditions [Wiggins, by Strawson,P]
A thing is necessarily its highest sortal kind, which entails an essential constitution [Wiggins, by Strawson,P]
Many predicates are purely generic, or pure determiners, rather than sortals [Wiggins]
The possibility of a property needs an essential sortal concept to conceive it [Wiggins]
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]
Objects can only coincide if they are of different kinds; trees can't coincide with other trees [Wiggins, by Sider]
9. Objects / B. Unity of Objects / 3. Unity Problems / e. Vague objects
Is the Pope's crown one crown, if it is made of many crowns? [Wiggins]
Boundaries are not crucial to mountains, so they are determinate without a determinate extent [Wiggins]
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]
Identity is an atemporal relation, but composition is relative to times [Wiggins, by Sider]

If I destroy an item, I do not destroy each part of it [Wiggins]
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 forget about individual or particularized essences [Wiggins]
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]
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]
Essences are not explanations, but individuations [Wiggins]
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]
Essentialism is best represented as a predicate-modifier: □(a exists → a is F) [Wiggins, by Mackie,P]
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
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]
The nominal essence is the idea behind a name used for sorting [Wiggins]
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]
9. Objects / E. Objects over Time / 1. Objects over Time
Identity means that the idea of a thing remains the same over time [Locke]
9. Objects / E. Objects over Time / 4. Four-Dimensionalism
It is easier to go from horses to horse-stages than from horse-stages to horses [Wiggins]
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 / E. Objects over Time / 9. Ship of Theseus
The question is not what gets the title 'Theseus' Ship', but what is identical with the original [Wiggins]
9. Objects / F. Identity among Objects / 1. Concept of Identity
Identity over a time and at a time aren't different concepts [Wiggins]
Hesperus=Hesperus, and Phosphorus=Hesperus, so necessarily Phosphorus=Hesperus [Wiggins]
9. Objects / F. Identity among Objects / 2. Defining Identity
The formal properties of identity are reflexivity and Leibniz's Law [Wiggins]
9. Objects / F. Identity among Objects / 3. Relative Identity
Same person, man or substance are different identities, belonging to different ideas [Locke]
Relative Identity is incompatible with the Indiscernibility of Identicals [Wiggins, by Strawson,P]
Relativity of Identity makes identity entirely depend on a category [Wiggins]
To identify two items, we must have a common sort for them [Wiggins]
9. Objects / F. Identity among Objects / 5. Self-Identity
Two things can't occupy one place and time, which leads us to the idea of self-identity [Locke]
9. Objects / F. Identity among Objects / 8. Leibniz's Law
Do both 'same f as' and '=' support Leibniz's Law? [Wiggins]
Substitutivity, and hence most reasoning, needs Leibniz's Law [Wiggins]
