In this article it is argued that the optical metaphor and critical practice of diffraction further developed by Donna Haraway and Karen Barad might be no less significant than the widely spread notion of reflection, when the questions of various practices of knowledge are addressed. By considering Paul Ramsden’s approach to learning/teaching and its underlying theory in higher education alongside Karen Barad’s methodology of diffraction, it is shown that Ramsden’s understanding of learning/teaching is rather based on the theoretical assumptions of (...) diffractive practice. His notion that teaching/learning are closely related and actively shaping each other, and that learners are not disconnected from the environment and their previous experiences with the subject matter and learning process itself, adds to Barad’s onto-epistemological position that knowers know the world at the same time as being the part of the world in its ongoing intra-activity. Ramsden’s understanding of relation is diffractive, because it is not about predefined binary entities and their fixed identities, but about layers and entanglements of various previous experiences and reactions to the learning environment. In addition, looking at learning/teaching processes through a different perspective also leads to a different approach to teaching and other ways of problem-solving. Both Ramsden and Barad distrust homologies, analogies, and causality-based conceptions of knowledge sharing. Instead, the ability to respond to an always new learning/teaching environment is assessed, which implies a diffractive type of sensitivity to the context, iterative process of re-turning, and the creation of dangerously indeterminate relationships and commitments. In this way, some of Barad’s philosophical notions, i.e., the diffraction pattern, intra-activity, returning, and others, also may acquire new practical content. (shrink)

In this article, I wish to engage in reflecting on the limits of affirmative and vitalist potentials visible in new materialist research. An enthusiastic note is clearly heard from within the new materialist perspective, for example in the important work of Rosi Braidotti. I offer an interpretation of her ‘The Ethics of Becoming Imperceptible’ in hopes of reflecting on the limits of the affirmative approach. This interpretation is fuelled by more hesitant notes also heard within new materialist research, tones expressing (...) doubts, tracing the limits of materialist, vitalist, affirmative takes and offering perspectives that turn to ‘a matter that fails to come to life’, ‘unproductive and devoid of relations’. This turn – according to my reading – is an effort to respond to the need to recognise ‘our today’ in its complexity. To fully grasp the landscapes of ‘our today’, I offer a concept of bare death (in dialogue with bare life as coined by Giorgio Agamben and as used by Braidotti) as a concept that relates to instances where something has died but cannot enter into the ‘generative powers of a Life’. It is depicted with references to the nuclear and plastic landscapes of the Anthropocene. Relating to those landscapes, I make use of an art installation by Pinar Yoldas, The Ecosystem of Excess, as a kind of companion for thinking about becoming and the transformation of life and death in order to respond to the ambivalent landscapes of ‘our today’ and to understand how death matters beyond the human self.

The work of Jacques Derrida is often characterized as anti-scientific, and his philosophy of language taken to mean we are sealed off from empirical reality, confined to our metaphysical prison. This position is reinforced by the fact that his forerunners, Heidegger and Nietzsche, did diminish the importance of the sciences, and argued that we are enclosed within the limits of language. Today, philosophy continues to deconstruct the nature/culture distinction, and challenge the meaning of materialism, but in recent decades has realized (...) that this work requires, in addition to a critique of the modern concept of science, a rehabilitation of the sciences outside their metaphysical definition. The fact that Derrida continues to be understood as an anti-science thinker has led to the exclusion of his work from this project. In this paper, I show that Derrida, while deconstruction the metaphysical concepts of science, nature and empiricism, in fact takes the mathematical sciences as an important force of deconstructing, and develops an interpretation of empiricism that points to a non-metaphysical understanding of it. From this perspective, Derrida's work is useful for thinking through the relation of the human to language and nature in the age of globalization and anthropogenic climate change. (shrink)

This essay traces the complex constellation of ideas that informs Anders's turn to the generalizing expression ‘the human’ in his postwar work. It mobilizes the properties of radioactive material and digital data, which are both curiously imperceptible to our senses, to discuss Anders’s insistence on the universalizing pronoun `we' and assess its significance in the contemporary world. To do so, it aligns Anders's work with current debates about the Anthropocene and critiques of the use of the term ‘the human’ in (...) postcolonial settings. (shrink)

Some Indigenous Australians have embraced developmental origins of health and disease (DOHaD) and epigenetic discourses to highlight the legacies of slow violence in a settler colonial context. Despite important differences between Indigenous and scientific knowledges, some Indigenous scholars are positioning DOHaD and epigenetics as a resource to benefit their communities. This article argues that time plays a crucial role of brokering disparate knowledge spaces in Indigenous discourses of postgenomics, with both Indigenous cosmological frames and DOHaD/epigenetics centring a circular temporal model. (...) Drawing on interview data with scientists who work in Indigenous health, and broader ethnographic work in Indigenous Australian contexts where epigenetics is deployed, this article explores how different circularities of space and time become entangled to co-produce narratives of historical trauma. We use the concept of biocircularity to understand the complex ways that Indigenous and postgenomic temporalities are separated and connected, circling each other to produce a postcolonial articulation of postgenomics as a model of collective embodiment and distributed responsibility.

Animals populate our artistic and philosophical discourses in critical ways. From Jacques Derrida's or Karen Barad's cat, to Donna Haraway's dog, to the fish in Lucien Castaing-Taylor and Véréna Paravel's Leviathan, these animals feature heavily in discussions regarding limits – the limits of the human and thus its relation with non-humans, but also the limits of knowledge itself. Cute or dangerous, real or fantasised, dead or alive: in this article, I juxtapose the various ways that such animals confront us with (...) what Jacques Derrida describes as “the point of view of the absolute other”. Similarly, recent texts stage encounters with animals – thus distributing agency towards a larger variety of beings, carving out space for a previously excluded non-human other. Yet these encounters are mediated in profoundly different ways. In researching how encounters with the animal are differentially inflected and “defracted” respective to the medium in which they are staged, this article invokes questions of form and style within the critical dialogue that attempts to centre non-human animals. Highlighting how formal decisions are not accidental, but rather integral, to the praxis of the philosophy of animality, this article aims to draw attention to how specific forms and styles allow for a moment of contact with a non-human other. To this end, this article examines three oft-cited encounters: Derrida's encounter with his cat, an intense stare with a fish in Leviathan, and Barad's inflection of Schrödinger's cat. This juxtaposition gives insight into the limits of certain styles of producing thought and critically reflects on these works in their discussion of non-human life and agency. (shrink)

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)
