Abstract: Many of us are tempted by the thought that the future is open, whereas the past is not. The future might unfold one way, or it might unfold another; but the past, having occurred, is now settled. In previous work we presented an account of what openness consists in: roughly, that the openness of the future is a matter of it being metaphysically indeterminate how things will turn out to be. We were previously concerned merely with presenting the view and exploring its consequences; we did not attempt to argue for it over rival accounts. That is what we will aim to do in this paper.

Abstract: In this paper we aim to disentangle the thesis that the future is open from theses that often get associated or even conflated with it. In particular, we argue that the open future thesis is compatible with both the unrestricted principle of bivalence and determinism with respect to the laws of nature. We also argue that whether or not the future (and indeed the past) is open has no consequences as to the existence of (past and) future ontology.

Introduction: Things change: objects come into existence, last for a while, go out of existence, move through space, change their parts, change their qualities, change in their relations to things. All this would seem to be uncontroversial. But philosophical attention to any of these phenomena can generate perplexity and has resulted in a number of long-standing puzzles. One of the most famous puzzles about change threatens to demonstrate that nothing can persist through time, that all existence is momentary at best. Let's use the term 'alteration' for the sort of change that occurs when a persisting object changes its properties.

Publisher’s Note:

How do things persist? Are material objects spread out through time just as they are spread out through space? Or is temporal persistence quite different from spatial extension? This key question lies at the heart of any metaphysical exploration of the material world, and it plays a crucial part in debates about personal identity and survival. This book explores and compares three theories of persistence — endurance, perdurance, and stage theories — investigating the ways in which they attempt to account for the world around us. Having provided valuable clarification of its two main rivals, the book concludes by advocating stage theory. Such a basic issue about the nature of the physical world naturally has close ties with other central philosophical problems. This book includes discussions of change and parthood, of how we refer to material objects at different times, of the doctrine of Humean supervenience, and of the modal features of material things. In particular, it contains new accounts of the nature of worldly vagueness, and of what binds material things together over time, distinguishing the career of a natural object from an arbitrary sequence of events. Each chapter concludes with a reflection about the impact of these metaphysical debates upon questions about our personal identity and survival.

Publisher’s note: This book investigates some of the central topics of metaphysics in the philosophical thought of the Maya people of Mesoamerica, particularly from the Preclassic through Postclassic periods. This book covers the topics of time, change, identity, and truth, through comparative investigation integrating Maya texts and practices — such as Classic Period stelae, Postclassic Codices, and Colonial-era texts such as the Popol Vuh and the books of Chilam Balam — and early Chinese philosophy.

Abstract: Here are some intuitions we have about the nature of space and time. There is something fundamentally different about the past, present, and future. What is definitive of the past is that the past events are fixed. What is definitive of the future is that future events are not fixed. What is definitive of the present is that it marks the objective ontological border between the past and the future and, by doing so, instantiates a particularly salient phenomenological property of nowness. Call the combination of these intuitions according to which there exists an objective present, a fixed past, and an open future, the intuitive view. I argue that, given the intuitive view, the possibility of backwards causation - and hence, for instance, backwards time travel - is problematic.

Abstract: In this paper, I argue that the thesis that time travel is logically possible, is inconsistent with the necessary truth of any of the usual 'open future objective present' models of the universe. It has been relatively uncontroversial until recently to hold that presentism is inconsistent with the possibility of time travel. I argue that recent arguments to the contrary do not show that presentism is consistent with time travel. Moreover, the necessary truth of other open future-objective present models which we might, prima facie, have supposed to be more amenable to the possibility of time travel, turn out also to be inconsistent with this possibility.

Introduction: McTaggart's argument for the conclusion that time does not exist is notoriously hard to understand. C. D. Broad says that when properly interpreted, its main part can be seen to be "a philosophical 'howler'."  Others see things in it that they regard as true and important, or if not true, then anyway important. But I have not seen any interpretation of it that seems to me to get it exactly right. And I think that it pays to get it right: there are lessons to be learned from consideration of what goes on in it. By way of reminder, McTaggart's argument has two parts. The first part aims at the conclusion that time does not exist unless the A series exists. The second part aims at the conclusion that the A series does not exist. It follows that time does not exist
