9. Objects / A. Existence of Objects / 1. Physical Objects
To be an object at all requires identity-conditions [Lowe]
Our commitment to the existence of objects should depend on their explanatory value [Lowe]
Objects are entities with full identity-conditions, but there are entities other than objects [Lowe]
Perhaps concrete objects are entities which are in space-time and subject to causality [Lowe]
9. Objects / A. Existence of Objects / 2. Abstract Objects / c. Modern abstracta
Bodies, properties, relations, events, numbers, sets and propositions are 'things' if they exist [Lowe]
9. Objects / A. Existence of Objects / 3. Objects in Thought
An object is an entity which has identity-conditions [Lowe]
9. Objects / A. Existence of Objects / 5. Individuation / a. Individuation
Some things (such as electrons) can be countable, while lacking proper identity [Lowe]
Neither mere matter nor pure form can individuate a sphere, so it must be a combination [Lowe]
9. Objects / A. Existence of Objects / 5. Individuation / b. Individuation by properties
Criteria of identity cannot individuate objects, because they are shared among different types [Lowe]
9. Objects / A. Existence of Objects / 5. Individuation / c. Individuation by location
Diversity of two tigers is their difference in space-time; difference of matter is a consequence [Lowe]
9. Objects / A. Existence of Objects / 5. Individuation / e. Individuation by kind
Individuation principles identify what kind it is; identity criteria distinguish items of the same kind [Lowe]
9. Objects / A. Existence of Objects / 6. Nihilism about Objects
Conventionalists see the world as an amorphous lump without identities, but are we part of the lump? [Lowe]
9. Objects / B. Unity of Objects / 2. Substance / d. Substance defined
A 'substance' is an object which doesn't depend for existence on other objects [Lowe]
On substances, Leibniz emphasises unity, Spinoza independence, Locke relations to qualities [Lowe]
9. Objects / B. Unity of Objects / 3. Unity Problems / c. Statue and clay
Statues can't survive much change to their shape, unlike lumps of bronze, which must retain material [Lowe]
The essence of lumps and statues shows that two objects coincide but are numerically distinct [Lowe]
The essence of a bronze statue shows that it could be made of different bronze [Lowe]
9. Objects / B. Unity of Objects / 3. Unity Problems / d. Coincident objects
Holes, shadows and spots of light can coincide without being identical [Lowe]
9. Objects / C. Structure of Objects / 5. Composition of an Object
The identity of composite objects isn't fixed by original composition, because how do you identify the origin? [Lowe]
9. Objects / D. Essence of Objects / 4. Essence as Definition
Grasping an essence is just grasping a real definition [Lowe]
9. Objects / D. Essence of Objects / 8. Essence as Explanatory
All things must have an essence (a 'what it is'), or we would be unable to think about them [Lowe]
Explanation can't give an account of essence, because it is too multi-faceted [Lowe]
9. Objects / D. Essence of Objects / 14. Knowledge of Essences
Knowing an essence is just knowing what the thing is, not knowing some further thing [Lowe]
If we must know some entity to know an essence, we lack a faculty to do that [Lowe]
9. Objects / E. Objects over Time / 2. Objects that Change
A 'substance' is a thing that remains the same when its properties change [Lowe]
9. Objects / E. Objects over Time / 3. Three-Dimensionalism
An object 'endures' if it is always wholly present, and 'perdures' if different parts exist at different times [Lowe]
9. Objects / E. Objects over Time / 4. Four-Dimensionalism
How can you identify temporal parts of tomatoes without referring to tomatoes? [Lowe]
9. Objects / E. Objects over Time / 9. Ship of Theseus
If 5% replacement preserves a ship, we can replace 4% and 4% again, and still retain the ship [Lowe]
A renovation or a reconstruction of an original ship would be accepted, as long as the other one didn't exist [Lowe]
If old parts are stored and then appropriated, they are no longer part of the original (which is the renovated ship). [Lowe]
9. Objects / F. Identity among Objects / 3. Relative Identity
A clear idea of the kind of an object must precede a criterion of identity for it [Lowe]
9. Objects / F. Identity among Objects / 4. Type Identity
One view is that two objects of the same type are only distinguished by differing in matter [Lowe]
Each thing has to be of a general kind, because it belongs to some category [Lowe]
9. Objects / F. Identity among Objects / 7. Indiscernible Objects
Identity of Indiscernibles (same properties, same thing) ) is not Leibniz's Law (same thing, same properties) [Lowe]
