In Alastair Morgan surveys the contributions of a loosely conceived school of psychiatrists, philosophers and social theorists to understanding and responding to madness during the years 1910-1980. Taking my cue from him, I highlight some of the contributors discussed in Morgan's book and reflect that although madness may be difficult or even impossible to articulate effectively in discourse it remains a 'limit experience' which demarcates and illuminates the contours of other thinking and being, including reason and activism. I discuss social and cultural factors that have dulled clinicians' sensitivities to the sounds of madness in recent decades and advocate the need for a reappraisal of our expertise and for a new activism today. What may at first appear as a failed clinical-philosophical tradition remains of professional relevance in today's rapidly transforming circumstances of practice both as inspiration and as cautionary tale.
