In order to answer this question, the article refers to Philip Pettit’s theory of the collective actor. Pettit conceptually challenges the widespread eliminativism concerning the idea of the collective actor. The alternative view taken into account is that of Michael Bratman, as it shows the influence of ideological precepts when tackling the question of collective actors.The aim of this comparison is to identify two elements in particular. The first is that, if the starting point of the elaboration coincides with an excessively individualistic precept, it will be hard to recognise the conceptual and mental autonomy that collective actors display in practice. The second is that, on the basis of Pettit’s ideas, it might be reasonable to attribute conceptual, cultural and social personality to specific post-national collective entities. This would be a rather significant outcome in a multicultural perspective that calls for a legal form of regulation.
