Critical posthumanism is an invitation to think differently about knowledge and educational relationality between humans and the more-than-human. This philosophical and political shift in subjectivity builds on, and is entangled with, poststructuralism and phenomenology. In this paper we read diffractively through one another the theories of Finnish architect Juhani Pallasmaa and feminist posthumanists Karen Barad and Rosi Braidotti. We explore the implications of the so-called ‘ontological turn’ for early childhood education. With its emphasis on a moving away from the dominant (...) role of human vision in educational research we show how videoing and photographing works as an apparatus in an analysis of data from an inner-city school in Johannesburg, South Africa. We are struck by children’s seeing with the ‘eyes of their skin’ and ‘seeing’ with/in the world, as their obvious distress is felt when a small tree sapling has been mowed down in a nearby park. We analyse the event with the help of a variation on Deleuze’s notion of ‘becoming-child’: ‘becoming-little’, and Anna Tsing’s ‘the arts of noticing’. ‘Becoming-little’ as a methodology disrupts the adult/child binary that positions ‘little’, younger humans as inferior to their ‘bigger’ fully human counterparts. We exemplify ‘becoming-little’ through 4 and 5 year-olds’ learning with the little tree and adopt Barad’s temporal diffraction to ‘see’ what is in/visible in the park: the extractive, exploitative, colonising mining practices of White settlers. These are still part of the land on which the park was created but are in/visible beneath the ‘skin’ of the earth. (shrink)
