Abstract

Hume argues that there are steadfast objects - objects not themselves successions at all, yet which co-exist with successions. Given Hume's account of moments as abstractions from temporal simples, there being steadfast objects entails there being single moments that co-exist with successions of moments. Thus time is more like a wall of variously sized bricks than like a line. I formalize the assumptions behind this surprising view, in order to make sense of it and in order to show that it is consistent. I note also that this view justifies the common-sense assumptions that time flows and is unlike space.
