‘New materialisms’ refers to a broad, contemporary, and significant movement of thought across the social sciences and cultural studies which attempts to (re)turn to, renew, or create alternative philosophies of matter. Such philosophies spring from multiple sources but are in general an attempt to bring the indissolubility of the social and environmental more forcefully into our analytical frames and modes of inquiry and tackle a perceived over-reliance on discourse and language in the so-called post-modern era of philosophy and social science. This movement in thought is underlaid by, and meets up with, the climate and biodiversity crises and the nature of the human condition (and modes of learning or becoming), within the field of environmental education. This volume brings together academics working at differing intersections of environmental education and new materialisms, highlighting tensions, knots, and lines of flight across and for research, practice, and theory. As such this collection draws on multiple interpretations and streams of thought within new materialisms and demonstrates their significance for those engaging with environmental education policy, practice and research. This book was originally published as a special issue of the journal Environmental Education Research.

This book makes the unorthodox claim that there is no such thing as mental health. It also deglamourises nature-based psychotherapies, deconstructs therapeutic landscapes and redefines mental health and wellbeing as an ecological process distributed in the environment - rather than a psychological manifestation trapped within the mind of a human subject. Traditional and contemporary philosophies are merged with new science of the mind as each chapter progressively examples a posthuman account of mental health as physically dispersed amongst things - emoji, photos, tattoos, graffiti, cities, mountains - in this precarious time labelled the Anthropocene. Utilising experimental walks, play scripts and creative research techniques, this book disrupts traditional notions of the subjective self, resulting in an Extended Body Hypothesis - a pathway for alternative narratives of human-environment relations to flourish more ethically. This transdisciplinary inquiry will appeal to anyone interested in non-classificatory accounts of mental health, particularly concerning areas of social and environmental equity - post-nature.
