Bringing together leading and emerging scholars in Systemic Functional Linguistics, this book explores the contributions made to SFL theory by James Robert Martin. A leading light in the field for 40 years, this book reviews, explores and develops the theoretical agendas set out in his momentous body of work. Focussed around the four themes of systemic functional theory, linguistic typology, educational linguistics and (positive) discourse analysis, chapters debate and develop the key concepts of Martin's work. Engaging with cutting edge theoretical debates in areas such as discourse-semantics, register and genre and affiliation, Discourses of Hope and Reconciliation examines Martin's lasting impact on the field, developing his momentous contributions to point the way to exciting future research directions in SFL.
