Abstract

The posthumanities constitute an affirmative, expanded development of the traditional humanities embedded within the posthuman convergence. Numerous changes impel recognition of wider forms and constituents of conditions no longer nameable simply as human, also implying mature relations to technology and science. The posthuman condition – in fields as diverse as military strategy, health, education and machine learning – brings entities and processes into transversal relation in ways that are normatively neutral but loaded with implications. Working in this condition is a task of the posthumanities. Being transversal implies risk. One such risk is the unexpected consequence. The article builds on Jevons, Merton, Guattari and Braidotti, to examine how transversality maps unexpected consequences. Transversality is also a pragmatic method to render problems multi-dimensional: expressing active forces and capacities under the radar of established forms of articulation. Short summaries of articles by contributing authors complete this introduction.
