This book takes up the question of whether past and future events exist. Two very different views are explored. According to one of these views, (presentism), advanced by Nikk Effingham, the present is special. Effingham argues that only the present things exist, but which things those are changes as time passes. Given presentism, although there once existed dinosaurs, they exist no more, and although you and I exist, at some time in the future we will come to exist no more. According to the alternative view (eternalism), advanced by Kristie Miller, our world is a giant four-dimensional block of spacetime in which all things, past, present, and future, exist. On this view, dinosaurs exist, it is just that they are not located at the current time. The book considers arguments for, and against, presentism and eternalism, including arguments that appeal to our best science, to the way the world seems to us to be in our experiences of time, change, and freedom, and to how to make sense of ordinary claims about the past. KEY FEATURES: Offers an accessible introduction to the philosophy of temporal ontology. Captures the process of philosophical debate, giving readers an insight into the craft of philosophy. Engages with and clearly explains state-of-the-art and cutting-edge research.

There are various arguments for the metaphysical impossibility of time travel. Is it impossible because objects could then be in two places at once? Or is it impossible because some objects could bring about their own existence? In this book, Nikk Effingham contends that no such argument is sound and that time travel is metaphysically possible. His main focus is on the Grandfather Paradox: the position that time travel is impossible because someone could not go back in time and kill their own grandfather before he met their grandmother. In such a case, Effingham argues that the time traveller would have the ability to do the impossible (so they could kill their grandfather) even though those impossibilities will never come about (so they won't kill their grandfather). He then explores the ramifications of this view, discussing issues in probability and decision theory. The book ends by laying out the dangers of time travel and why, even though no time machines currently exist, we should pay extra special care ensuring that nothing, no matter how small or microscopic, ever travels in time.
