Preview

This paper argues that time travel is possible, and that the paradoxes of time travel are oddities, not impossibilities. The defence of the possibility of time travel involves a commitment to enduring things having temporal as well as spatial parts, psychological continuity and connectedness and causal continuity as criteria of personal identity, and a distinction between external and personal time.

Keywords: backward causation; paradox of time travel; personal identity; temporal parts; time; time travel
