How do ordinary objects persist through time and across possible worlds? How do they manage to have their temporal and modal properties? These are the questions adressed in this book which is? "guided tour of theories of persistence". The book is divided in two parts. In the first, the two traditional accounts of persistence through time (endurantism and perdurantism) are combined with presentism and eternalism to yield four different views, and their variants. The resulting views are then examined in turn, in order to see which combinations are appealing and which are not. It is argued that the 'worm view' variant of eternalist perdurantism is superior to the other alternatives. In the second part of the book, the same strategy is applied to the combinations of views about persistence across possible worlds (trans-world identity, counterpart theory, modal perdurants) and views about the nature of worlds, mainly modal realism and abstractionism. Not only all the traditional and well-known views, but also some more original ones, are examined and their pros and cons are carefully weighted. Here again, it is argued that perdurance seems to be the best strategy available.

Influential accounts of persistence--how ordinary objects persist through time--examine the perdurantist, exdurantist, and endurantist approaches and provide an overview of the topic.

Some of the world's specialists provide in this handbook essays about what kinds of things there are, in what ways they exist, and how they relate to each other. They give the word on such topics as identity, modality, time, causation, persons and minds, freedom, and vagueness.

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.

The notion of possible worlds has played a decisive role in postclassical narratology by awakening interest in the nature of fictionality and in emphasizing the notion of world as a source of aesthetic experience in narrative texts. As a theory concerned with the opposition between the actual world that we belong to and possible worlds created by the imagination, possible worlds theory has made significant contributions to narratology. Possible Worlds Theory and Contemporary Narratology updates the field of possible worlds theory and postclassical narratology by developing this theoretical framework further and applying it to a range of contemporary literary narratives. This volume systematically outlines the theoretical underpinnings of the possible worlds approach, provides updated methods for analyzing fictional narrative, and profiles those methods via the analysis of a range of different texts, including contemporary fiction, digital fiction, video games, graphic novels, historical narratives, and dramatic texts. Through the variety of its contributions, including those by three originators of the subject area—Lubomír Doležel, Thomas Pavel, and Marie-Laure Ryan—Possible Worlds Theory and Contemporary Narratology demonstrates the vitality and versatility of one of the most vibrant strands of contemporary narrative theory.

This book uses the formal semantics of counterfactual conditionals to analyze the problem of non-locality in quantum mechanics. Counterfactual conditionals (subjunctive conditionals) enter the analysis of quantum entangled systems in that they enable us to precisely formulate the locality condition that purports to exclude the existence of causal interactions between spatially separated parts of a system. They also make it possible to speak consistently about alternative measuring settings, and to explicate what is meant by quantum property attributions. The book develops the possible-world semantics of quantum counterfactuals using David Lewis’s famous approach as a starting point but modifying it significantly in order to achieve compatibility with the demands of the special theory of relativity as well as quantum mechanics. There have been several attempts to use counterfactual semantics to strengthen Bell’s theorem and its cognates such as the GHZ and Hardy theorems. These are critically evaluated in the book. Finally, a counterfactual reconstruction of the EPR argument and Bell’s theorem is proposed that sheds a new light on their philosophical consequences regarding the relations between realism and local causation.

Should you care less about your distant future? What about events in your life that have already happened? How should the passage of time affect your planning and assessment of your life? Most of us think it is irrational to ignore the future but completely harmless to dismiss the past. But this book argues that rationality requires temporal neutrality: if you are rational you don't engage in any kind of temporal discounting. The book draws on puzzles about real-life planning to build the case for temporal neutrality. How much should you save for retirement? Does it make sense to cryogenically freeze your brain after death? How much should you ask to be compensated for a past injury? Will climate change make your life meaningless? Meghan Sullivan considers what it is for you to be a person extended over time, how time affects our ability to care about ourselves, and all of the ways that our emotions might bias our rational planning. Drawing substantially from work in social psychology, economics and the history of philosophy, the book offers a systematic new theory of rational planning.
