In this article I attempt to reshape the agent-structure debate in Internat
ional Relations which has become increasingly confused and fruitless. I do
so by first rejecting two things - (1) the agent-structure dichotomy, presu
pposed in the debate, in favour of the age-old classification of causative
factors into mechanistic, volitional and coincidental ones; and (2) the exp
lanation-understanding dichotomy, prevalent in the debate, in favour of the
idea of 'narrative intelligibilifying'. I also draw attention to narrative
as a factor constitutive of agents and structures, and offer a modified ve
rsion of structurationism, while rejecting a version of scientific realism
sometimes associated with it. As to how one form of social structure moves
towards another, I suggest that, at its most ambitious, this is a world-his
torical question, and that how the three causative factors are combined in
addressing this question is as fascinating as it is vital for our self-unde
rstanding as human beings.
