This ground-breaking work addresses the central question of the nature of professional judgement and deliberation that has recently come to the fore in the academic literature of profession and professionalism. It proposes a marked shift away from technical-rational approaches to professional decision-making in favour of reflection and deliberation informed by responsible moral judgement. This book is unique in bringing together key authors from different professional fields to address the issue of professional wisdom in a cross-professional and multidisciplinary way.
