Persistence and spacetime

Language: eng
Number of pages: 233
ISBN-13: 9780199579921
Subjects: Generalized spaces; Special relativity (Physics); Space and time
Other titles: Persistence & spacetime
Description: How do material objects persist through time and survive change? Are they three-dimensional entities extended in space, or are they four-dimensional spacetime 'worms'? Balashov shows how the theory of relativity supports four-dimensionalism and in so doing illuminates a wide range of metaphysical issues.
Notes: Includes bibliographical references (p. [217]-225) and index.
