Practising Immanence: Living with Theory and Environmental Education makes creative contributions to both qualitative inquiry and environmental education by exploring how each of these ideas seep and fuse into one another, creating a space where methodology becomes pedagogy, and where each of these is already always environmental: indivisible with life. Clarke’s energising and innovative approach offers a challenge to conventional research practices and shows ways in which inquiry can be done differently. Drawing on new materialisms, affect theory and the practical philosophy of Gilles Deleuze and Felix Guattari, the book details the PhD journey of the author, merging stories and theory (and stories of theory) in the production of eight ‘haecceities’ – a philosophical concept which prioritises the thisness of a thing or event. This move allows a novel methodological approach whereby the haecceities act as sites of variation on the events of the book: the self as unstable and posthuman; the environment as everything (immanent) rather than as an overly romantic or a green version of nature; and the tensions that these moves create for ethical orientations in education, inquiry and life in the Anthropocene. Practising Immanence brings theory to life through a diffractively critical style and a unique approach to environmental pedagogic practice. This radical and vitalising book will be of interest to those inspired to explore environmental problems and inquiry with each other and to those drawn to creative-relational, narrative, embodied and post-qualitative approaches to research.
