“…It is still worth including this clause, as it makes Adequacy Condition 2, as well as our arguments below, even more difficult to resist. That there are 'no other relevant differences' between a and a* is here stipulated to mean that a and a* do not differ with regard to factors such as causation, rights-violations, the agent's motives or intentions, or other factors that opponents of well-being counterfactualist accounts have sometimes held to be relevant to harm and benefit (see, for example, Woodward [1986], Harman [2009], Gardner [2015], and Purves [2019]). Without this ceteris paribus clause, Adequacy Condition 2 might be rejected (although not by well-being counterfactualists) on, for instance, the ground that, even if W Sa is much higher than W Sa* and a* would not harm S, it can still be true that a would harm S so long as a but not a* would cause S to occupy the relevant well-being level.…”
