Abstract

This paper examines personal identity in the context of the Everett interpretation of Quantum Mechanics. According to Everett, the universe branches many – perhaps an infinite number of – times per second. This leads to a universe in which many versions of ‘you’ exist, many of whom are living different lives to yours. How are we to make sense of the continuation of the self in this context? This is of particular importance for Christian theism, which is committed to an enduring self that can be held responsible for past actions and can develop an ongoing relationship with God. The paper argues that the best way to understand identity in the Everettian world as fundamentally narrative in nature.
