Theodore Sider

'Logic for Philosophy' is an introduction to logic for students of contemporary philosophy. It covers basic approaches to logic, as well as extensions of standard logic and the elementary philosophy of logic.

Logic for philosophy

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 offour-dimensionalism include novel arguments based on time travel, the debate beween spacetime substantivalists 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 to four-dimensionalism, including discussion of the problem of the rotating homogenous disk. Four Dimensionalism is an originaland highly readable study of the metaphysics of time and identity.

An Ontology of Persistence and Time

Four-dimensionalism

Theodore Sider presents a broad new vision of metaphysics centred on the idea of structure. To describe the world well we must use concepts that 'carve at the joints', so that conceptual structure matches reality's structure. This approach illuminates a wide range of topics, such as time, modality, ontology, and the status of metaphysics itself.

Writing the Book of the World

Earl Brink Conee

The questions of metaphysics are the deepest and most puzzling questions there are. What is time? Am I free in my actions? What makes me the same person I was as a child? What is it for one thing to cause another? Riddles of Existence is the first book ever to make metaphysics genuinely accessible and fun. Its lively, informal style brings the riddles to life and shows how stimulating it can be to think about them. No philosophical background is required to enjoy this book: anyone who has thought about life's most profound questions will find plenty to provoke and entertain them here.

Contemporary Debates in Metaphysics

Earl Conee

The questions of metaphysics are among the deepest and most puzzling. What is time? Am I free in my actions? What makes me the same person I was as a child? Why is there something rather than nothing? Riddles of Existence makes metaphysics genuinely accessible, even fun. Its lively, informal style brings the riddles to life and shows how stimulating they can be to think about. No philosophical background is required to enjoy this book: anyone wanting to think about life's most profound questions will find Riddles of Existence provocative and entertaining.

Four-Dimensionalism

Metaphysics is sensitive to the conceptual tools we choose to articulate metaphysical problems. Those tools are a lens through which we view metaphysical problems, and the same problems will look different when we change the lens. In this book, Theodore Sider identifies how the shift from modal to "postmodal" conceptual tools in recent years has affected the metaphysics of science and mathematics. He highlights, for instance, how the increased consideration of concepts of ground, essence, and fundamentality has transformed the debate over structuralism in many ways. Sider then examines three structuralist positions through a postmodal lens. First, nomic essentialism, which says that scientific properties are secondary and lawlike relationships among them are primary. Second, structuralism about individuals, a general position of which mathematical structuralism and structural realism are instances, which says that scientific and mathematical objects are secondary and the pattern of relations among them is primary. And third, comparativism about quantities, which says that particular values of scientific quantities, such as having exactly 1000g mass, are secondary, and quantitative relations, such as being-twice-as-massive-as, are primary. Sider concludes these discussions by considering the meta-question of when theories are equivalent and how that impacts the debate over structuralism.
