When we speak of perceptions, behaviours and attitudes towards the current ecological crisis, we often refer to the individual, an abstract and self-consistent subject who seems to exist independently of its own material and symbolic relationships. Often the problem of responding to crisis situations is resolved in an equally individualised intervention on the subject's "mind" to change his/her behaviour. Drawing on empirical material from the ethnographic study of everyday life and climate justice movements, in this presentation I problematise this reductive approach to subjectivity and the psyche in the context of the climate crisis. I propose to rethink and re-enact the subject as a complex entity that is constructed in the encounter of multiple planes - corporeal, affective, emotional, cognitive... - and always in relation to an "outside" that co-constitutes it: from social relations to the physical environment, from the existing social order to everyday practices. Within this framework, affect and desire are central issues in the relationship between subject and ecologies (near and far), and mark relationalities that move beyond the experience of the individual to connect to spaces, objects and living bodies within the subjective field of life. This suggests the importance of conceiving subjective change within a broader and more complex process of collective, ecological, sociomaterial transformation.
