Abstract: Discusses Sidgwick's challenge to S; temporal and interpersonal neutrality; analogies between ‘I’ and ‘now’, or oneself and the present. It presents arguments that appeal to these analogies; how S is incompletely relative, making it vulnerable to attack from two directions. S can be challenged both by theories like CP, which are relative both to persons and to times, and by those moral theories that are both temporally and interpersonally neutral.
