Abstract

If you split yourself down the middle to become two people, would you survive the process? And, if you did, would your other half be your child, your clone or your sibling? Would this create two instances of the same you, existing simultaneously in two places at the same time; or would it create two entirely new people, causing you to suddenly cease to exist? While such thought experiments raise baffling questions about personal identity, there is a more fundamental problem I want to consider: would splitting in two be an instance of reproduction or an entirely different kind of process?
