Touch the Untouchable

Quoted By:

One solution to this paradox may come from the concept of four-dimensionalism. David Lewis and others have proposed that these problems can be solved by considering all things as 4-dimensional objects. An object is a spatially extended three-dimensional thing that also extends across the 4th dimension of time. This 4-dimensional object is made up of 3-dimensional time-slices. These are spatially extended things that exist only at individual points in time. An object is made up of a series of causally related time-slices. All time-slices are numerically identical to themselves. And the whole aggregate of time-slices, namely the 4-dimensional object, is also numerically identical with itself. But the individual time-slices can have qualities that differ from each other the unOne solution to this paradox may come from the concept of four-dimensionalism.
