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
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 / C. Structure of Objects / 8. Parts of Objects / c. Wholes from parts
9667 Mereological composition is unrestricted: any class of things has a mereological sum [Lewis]
13268 There are no restrictions on composition, because they would be vague, and composition can't be vague [Lewis, by Sider]
9. Objects / D. Essence of Objects / 7. Essence and Necessity / a. Essence as necessary properties
13793 An essential property is one possessed by all counterparts [Lewis, by Elder]
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 / 1. Objects over Time
9663 A thing 'perdures' if it has separate temporal parts, and 'endures' if it is wholly present at different times [Lewis]
9. Objects / E. Objects over Time / 2. Objects that Change
14737 Properties cannot be relations to times, if there are temporary properties which are intrinsic [Lewis, by Sider]
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]
9664 Endurance is the wrong account, because things change intrinsic properties like shape [Lewis]
9665 There are three responses to the problem that intrinsic shapes do not endure [Lewis]
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
14726 Four-dimensionalists assert 'temporal parts', 'perduring', and being spread out over time [Sider]
14728 4D says intrinsic change is difference between successive parts [Sider]
14729 4D says each spatiotemporal object must have a temporal part at every moment at which it exists [Sider]
9. Objects / E. Objects over Time / 5. Temporal Parts
14730 Temporal parts exist, but are not prior building blocks for objects [Sider]
14731 Temporal parts are instantaneous [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 / E. Objects over Time / 12. Origin as Essential
19280 I can ask questions which create a context in which origin ceases to be essential [Lewis]
9. Objects / F. Identity among Objects / 5. Self-Identity
15968 Identity is simple - absolutely everything is self-identical, and nothing is identical to another thing [Lewis]
9. Objects / F. Identity among Objects / 6. Identity between Objects
15969 Two things can never be identical, so there is no problem [Lewis]
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]
