Single Idea 9665

[filed under theme 9. Objects / E. Objects over Time / 3. Three-Dimensionalism ]

Full Idea

The problem for the endurance view of temporary intrinsic properties like shape is met be either saying shape is a disguised relational property, or only present properties are intrinsic, or the shapes belong to different things (perdurance).

Gist of Idea

There are three responses to the problem that intrinsic shapes do not endure

A Reaction

[compressed] It is certainly implausible to deny that shape is a feature of all physical objects. Or it appears to be. Shapes are hard to pin down at the quantum level. How do you sharply divide moments for the perdurance view? ...


The 12 ideas with the same theme [objects extend in space, but not in time]:

'Dense' time raises doubts about continuous objects, so they need 'continuous' time [Harré/Madden]
Endurance is the wrong account, because things change intrinsic properties like shape [Lewis]
There are three responses to the problem that intrinsic shapes do not endure [Lewis]
3-D says things are stretched in space but not in time, and entire at a time but not at a location [Fine,K]
Genuine motion, rather than variation of position, requires the 'entire presence' of the object [Fine,K]
An object 'endures' if it is always wholly present, and 'perdures' if different parts exist at different times [Lowe]
Three-dimensionalists assert 'enduring', being wholly present at each moment, and deny 'temporal parts' [Sider]
Some might say that its inconsistency with time travel is a reason to favour three-dimensionalism [Sider]
Endurance theory can relate properties to times, or timed instantiations to properties [Hawley]
Endurance is a sophisticated theory, covering properties, instantiation and time [Hawley]
The persistence of objects seems to be needed if the past is to explain the present [Haslanger]
Persistence makes change and its products intelligible [Haslanger]
