Mental time travel, agency, and responsibility

We have argued elsewhere (2002) that moral responsibility over time depends in part upon the having of psychological connections which facilitate forms of self-control. In this paper we explore the importance of mental time travel ' our ordinary ability to mentally travel to temporal locations outside the present, involving both memory of our personal past and the ability to imagine ourselves in the future ' to our agential capacities for planning and control. We suggest that in many individuals with dissociative disorders, forms of amnesia, or other frontal lobe damage, our capacity for mental time travel is impaired, resulting in commensurate losses to agency, autonomy, and a forensic condition essential for holding persons responsible: in legal terms, the capacity for mens rea.
