[objects extend in space, but not in time]

12 ideas
'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]
