Critical realism and 'downward causality': professional rugby union as an extreme sport.

Only too often critical realist contributions to understanding and explaining social phenomena fall into one of two discrete categories: exercises in philosophy or social theory, or empirical research that strikes as more or less atheoretical. This paper continues a long-term project to build bridges between abstruse issues of philosophy and theory and attempts to grasp the 'how' and 'why' of actual social events. The topic selected is elite professional rugby union and the principal theme is its emergence as an extreme sport and the risk of serious injury. It is argued that the injurious nature of elite rugby has its causal genesis in the professionalization of the sport and that a critical realist-oriented sociology has an important contribution to make in framing and gasping how and why this is.
