Terry erroneously says that the agency-structure dualism presupposes that agency belongs to only to individuals. It's true that the discussion so far of agents has only mentioned individual agents. Terry is right to say that for Marx classes can be agents. This is not unproblematic, since of course classes act only through the agency of their constituent individual members. But I think is is true. However, the agency-structure dualism applies here too. Class and other group agents face structural constraints on their choices and actions. This part of what is meant, for instance,m when we say a situation is (or is not) revolutionary. --Justin
