Abstract

McTaggart's negative thesis in his proof for the unreality of time, which contends that the A-series is contradictory, is still today upheld as a proof of the unreality of the properties of past, present, and future, and of the `flow of time'. In my paper, I defend the possibility of a complete and consistent description of the A-series, thus refuting McTaggart's negative thesis. I show that the failure to acknowledge the possibility of such a description is due to an ambiguity in natural language. Once this ambiguity is clarified, and in light of the disanalogy between time and space, the usual description of the A-series, `Event e was future, is present, and will be past', is shown to be a successful description of the change in the temporal A-properties
