Four-Dimensionalism by Theodore Sider, Hardcover | Indigo Chapters

Four-Dimensionalism defends the thesis that the material world is composed of temporal as well as spatial parts. This defense includes a novel account of persistence over time, new arguments in favour of the four-dimensional ontology, and responses to the challenges four-dimensionalism faces. Theodore Sider pays particular attention to the philosophy of time, including a strong series of arguments against presentism, the thesis that only the present is real. Arguments offered in favour of four-dimensionalism include novel arguments based on time travel, the debate beween spacetimesubstantivalists and relationalists, and vagueness. Also included is a comprehensive discussion of the paradoxes of coinciding material objects, and a novel resolution of those paradoxes based on temporal counterpart theory. In conclusion Sider replies to prominent objections tofour-dimensionalism, including discussion of the problem of the rotating homogenous disk. Four Dimensionalism is an original and highly readable study of the metaphysics of time and identity. | Four-Dimensionalism by Theodore Sider, Hardcover | Indigo Chapters
