Hedley Bull is one of the most influential theorists of his generation
. His attempt to build a theory of international politics which was ne
ither the servant of realpolitik nor the child of Wilsonian idealism r
emains the most convincing framework for understanding state practice.
This article seeks to reassess Bull's contribution to the subject by
addressing two important questions. In the first half of the article t
he authors argue that Bull became increasingly aware that his theory o
f international society offered only a partial escape from the ethical
paucity of E. H. Carr's political realism. For this reason, in his la
ter years Bull adumbrated a more solidarist theory of international so
ciety. They argue that despite his attraction to solidarism, the reali
st in Bull prevented him from embracing a convincing solidarist theory
of world politics. The second half of the article examines the releva
nce of Bull's categories of pluralism and solidarism for thinking abou
t the ethics of statecraft in the post-Cold War world. By focusing on
the response of the society of states to humanitarian crises, the auth
ors consider how far solidarist sentiments have penetrated the conscio
usness of state leaders, reflecting on Bull's cove contention that the
re is an interdependence between order and justice in the society of s
tates.
