 Communities such as those just mentioned are groups, each of them a whole [totum] made up of persons (and perhaps of other groups), their unity being not merely one of composition or conjunction or continuity, but rather of order, in two dimensions: (i) of the parts (members) as coordinating with each other, and (ii) of the group and its members to its organizing purpose or end (finis). Of these, (ii) is the more explanatory, as Aquinas argues at the very beginning of his commentary on Aristotle’s Ethics.
