ABSTRACT. We are happy to present this year’s fourth issue of Knowledge Cultures. If its subject matter could be distilled into a single theme, it would be that there are several guises to criticality. It has always been our aim, as editors of Knowledge Cultures, to ensure that critical approaches to oft-difficult topics are given a forum. We do not necessarily consider ourselves unique in that regard, but we hope that the journal is known for paying particular attention to the big issues that present themselves in our current epoch. These issues are often new manifestations of old problems, but their new visage calls for a refreshed critical regard. The authors in this issue are aware that there is some thread that has long existed that must be addressed alongside the recently disclosed problem: this orientation towards the ‘old’ problem and the ‘new’ forms the basis for a culture of knowledge, to the extent that it represents a skill that consciously links the modern issue with its long-lived parent. We are grateful to the authors for re-enacting the new as, really, something persistent. pp. 11–13
