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 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.
