 As with the most discussed issues in the theory of collective intentionality, there is a fundamental divide between individualist and non-individualist (or collectivist) conceptions of collective responsibility (cf. May 1992; Miller &amp; Makela 2005; Miller 2006). The former hold that only individual agents or natural persons can be properly held responsible, while the latter hold that some collectives do count as subjects of responsibility (cf. Mathiesen 2006; Pettit 2007b; Hindriks 2009); depending on context and group size, there may be a number of tenable intermediate positions on this spectrum. In any case, it seems plausible to assume that one’s account of collective responsibility should not be starkly discontinuous with one’s account of collective agency. And it seems hardly spectacular to assume that a differentiated account of collective intentionality can inform a differentiated account of collective responsibility. Systematically minded social philosophers are called upon to take up these challenges.
