Scholarly debates often entertain the perspective that 'the frontier makes the man'. This book considers human-frontier relations to be mutually constitutive and transformative and explores the range of 'frontiers' that we encounter in different 'spheres' of our life. It recognises that in experiences of extreme landscapes, risky physical and social endeavours, or at the fringes of human experience, a more complex and subtle emotional geography can be charted. This book seeks to curate the experiences of frontiers as spaces of transformation, exploration and adventure. It reflects on the nature, form and experience of frontiers in terms of individual engagements, cultural encounters, extreme or challenging experiences, danger and risk. It considers the frontier an experience where meaning is constituted from affective and emotional registers. It draws on a rich seam of critique that has developed that troubles the centrality of representational thinking, drawing on the more-than-human, the more-than-representational, post-humanism, new materialities and the politics of affect. With contributions from scholars, explores, and researchers, the chapters offer accounts of individual experiences and insightful interpretations from geographical, historical, feminist, post-colonial, anthropological, cosmopolitan and cultural studies perspectives.
