Through its focus on the question of circulation, world history attained a central position amongst the historical configurations in the last decade. Indicative of our fundamentally changing world, the past thereby reveals itself to have been shaped by commercial, human and intellectual flows of global dimension. The history of science has been particularly receptive to such methodological developments, especially with regard to works influenced by a markedly social approach to science and knowledge, which has focused for some time on the analysis of intellectual networks. From the French provincial Enlightenment to Athansius Kircher's circles—including the relationships of patronage of mathematicians and court philosophers—social, intellectual and epistemological configurations have been designed, allowing us to consider different scales in the circulation of knowledge.

Ever since the issue has been a controversial one and has received a great deal of attention from scholars, not least thanks to the publication of Eric Williams's book “Capitalism and Slavery”. To a large extent the debate has been concerned with the issue of whether the profits from colonialism were large enough to have a decisive effect upon, or at least contribute to, the industrialisation of Britain and/or other countries in Europe.
