Collective Action and Social Ontology in Thomas Aquinas

Abstract In this paper I argue that there are resources in the work of Thomas Aquinas that amount to a unique approach to what David P. Schweikard and Hans Bernhard Schmid’s call the “Central Problem” facing theorists of collective intentionality and action. That is to say, Aquinas can be said to affirm both (1) the “Individual Ownership Claim” and (2) the “Irreducibility Claim,” coherently and compellingly. Regarding the Individual Ownership Claim, I argue that Aquinas’s concept of “general virtue” (virtus generalis) buttresses an account of the way in which individuals act collectively qua individuals, i.e., without invoking hive minds or other scientifically problematic phenomena. Further, with respect to the Irreducibility Claim (2), I argue that Aquinas’s concept of “common good” (bonum commune) offers an account of the way in which some powers and acts of social groups are importantly irreducible to those of their members. Considered together, I argue that these two positions in Aquinas are correlative, and therefore amount to a coherent account of collective action and group agency, respectively.
