This E-Special Issue collects together 11 articles from the archives of Theory, Culture & Society. These articles all articulate and debate the contribution of what some have described as either ‘complex complexity’ or ‘general complexity’. In contrast to reductionist or restricted attempts to understand complexity, the articles collected here move away from the tendency to assume mastery of complexity by expounding a set of universal and simple laws. Rather, the position of general complexity is that we cannot grasp the complexity (...) of the world in its complexity, and therefore depend upon models which are always incomplete, provisional and contingent. Yet, these models make knowledge and action possible, and it is therefore the contribution of general complexity to provide the means through which we can ethically and pragmatically engage with complexity in the hope of realizing alternative, perhaps better, worlds.
