For example, if person A were to be split into two separate people (the brain would split in half), we would have two new individuals, who we can refer to as “ person B” and “person C” (Rocca, 2014). Now, if both of these individuals had the same kind of continuity with “A” and both remembered the thoughts and actions of “A,” then both “B” and “C” would be equally good candidates for being “A” (Rocca, 2014). However, note that both "B" and "C" cannot be identical to "A" because "B" and "C" are not identical to each other (Rocca, 2014). Therefore, it would be arbitrary if one of "B" and "C" were identical to "A", and this would have too much continuity, so neither is identical to "A" (Rocca, 2014). As stated by Derek Parfit, “How could double success, double continuity, result in a failure of personal identity over time?” (Rock,
