 Another question to raise, if only to set aside on this occasion, is whether the only sort of indispensability that can support the group mind hypothesis is of the theoretical/explanatory sort. One might, for example, consider whether the Rovane/Pettit line of thought could be run with the assumption that the indispensability of such groups is practical in nature, perhaps a condition for a sort of agency that individuals can and do exercise (Roth 2014a, 140–141; Pettit 2015, 1642).
