9. Objects / A. Existence of Objects / 5. Individuation / e. Individuation by kind
14745
|
If sortal terms fix the kind and the persistence conditions, we need to know what kinds there are [Sider]
|
9. Objects / B. Unity of Objects / 3. Unity Problems / b. Cat and its tail
16058
|
Dion and Theon coexist, but Theon lacks a foot. If Dion loses a foot, he ousts Theon? [Chrysippus, by Philo of Alexandria]
|
14740
|
If Tib is all of Tibbles bar her tail, when Tibbles loses her tail, two different things become one [Sider]
|
9. Objects / B. Unity of Objects / 3. Unity Problems / c. Statue and clay
14752
|
Artists 'create' statues because they are essentially statues, and so lack identity with the lump of clay [Sider]
|
9. Objects / B. Unity of Objects / 3. Unity Problems / d. Coincident objects
14743
|
The stage view of objects is best for dealing with coincident entities [Sider]
|
9. Objects / C. Structure of Objects / 5. Composition of an Object
14747
|
'Composition as identity' says that an object just is the objects which compose it [Sider]
|
9. Objects / D. Essence of Objects / 12. Essential Parts
14757
|
Mereological essentialism says an object's parts are necessary for its existence [Sider]
|
9. Objects / E. Objects over Time / 2. Objects that Change
16059
|
Change of matter doesn't destroy identity - in Dion and Theon change is a condition of identity [Chrysippus, by Long/Sedley]
|
9. Objects / E. Objects over Time / 3. Three-Dimensionalism
14727
|
Three-dimensionalists assert 'enduring', being wholly present at each moment, and deny 'temporal parts' [Sider]
|
14738
|
Some might say that its inconsistency with time travel is a reason to favour three-dimensionalism [Sider]
|
9. Objects / E. Objects over Time / 4. Four-Dimensionalism
14729
|
4D says each spatiotemporal object must have a temporal part at every moment at which it exists [Sider]
|
14728
|
4D says intrinsic change is difference between successive parts [Sider]
|
14726
|
Four-dimensionalists assert 'temporal parts', 'perduring', and being spread out over time [Sider]
|
9. Objects / E. Objects over Time / 5. Temporal Parts
14731
|
Temporal parts are instantaneous [Sider]
|
14730
|
Temporal parts exist, but are not prior building blocks for objects [Sider]
|
14758
|
How can an instantaneous stage believe anything, if beliefs take time? [Sider]
|
14762
|
Four-dimensionalism says temporal parts are caused (through laws of motion) by previous temporal parts [Sider]
|
9. Objects / E. Objects over Time / 9. Ship of Theseus
14741
|
The ship undergoes 'asymmetric' fission, where one candidate is seen as stronger [Sider]
|
9. Objects / F. Identity among Objects / 8. Leibniz's Law
14754
|
If you say Leibniz's Law doesn't apply to 'timebound' properties, you are no longer discussing identity [Sider]
