  Daniel Bell (1919–2011) and Manuel Castells (1942–) are the grand theorists of the information age. The article provides a detailed, up-to-date, comparative analysis of their writings. It begins with their methodologies, identifying numerous commonalities in their post-Marxian frameworks. The substance of their theories is then examined, where it is shown that both plausibly explain contemporary social reality in terms of the interplay of three forces: the information technology revolution, the restructuring of capitalism and the innovational role of culture. There are found to be major similarities in their accounts (the Kantian interpretation, social stratification) but also significant divergences (role of science, the fourth world, the normative content of culture). Suitably combined, Bell’s and Castells’s thought goes a long way towards delivering a persuasive sociological theory of the global information society. However, the article concludes by suggesting that extensive further work is needed to clarify the precise relationships between the three factors and their relative weightings in the equations required to explain recent social change.
