We conclude that the task of reconciling individualist permitting reasons and the partial aggregation of requiring reasons with each other and with the overall account is more extensive than Pummer suggests. Further, we argue that while individualist permitting reasons are an interesting and potentially very constructive contribution to the non-consequentialist discussion of our duties to assist, more must be done to establish their plausibility.20en© 2025 Kirsten Mann and Christian Barry.aggregationduties to rescueeffective altruismsaving the greater number202510.1163/17455243-20254819105005063392
