 To get an intuitive idea of what temporal parts are supposed to be, think of a film strip depicting you as you walk across a room. It is made up of many frames, and each frame shows you at a moment of time. Now picture cutting the frames, and stacking them, one on top of another. Finally, imagine turning the stack sideways, so that the two-dimensional images of you are all right-side-up. Each image of you in one of these frames represents a temporal part of you, in a specific position, at a particular location in space, at a single moment of time. And what you are, on this way of thinking, is the fusion of all these temporal parts. You are a “spacetime worm” that curves through the four-dimensional manifold known as spacetime. Moreover, on this view, what it is to have a momentary property at a time is to have a temporal part at the time that has the property in question. So you are sitting right now in virtue of the fact that your current temporal part is sitting.
