Folding Nature Back Upon Itself: Aristotle and the Rebirth of Physis

“Folding Nature Back Upon Itself: Aristotle and the Rebirth of Physis,” confronts us with nature’s receding presence and proposes to think through a rebirth of physis. Following Aristotle’s concept of physis, this paper locates two axes along which such a rethinking of physis can take place. The first axis is vertical, and turns around the fundamental tension that each natural being faces in seeking to overcome its own matter in order to reach transcendence. The second axis is horizontal, and follows Aristotle’s ideas that physis cannot unfold unless aided, stimulated, nurtured and enforced by external factors such as one’s environment, food, art, technology, and politics. This paper argues that vertical transcendence needs to be rethought to accommodate earthy, individual natural flourishing. Horizontal transcendence (e.g. rethinking the collaboration between different species and the collaboration between art and nature) may allow physis the kind of vertical transcendence that leads to its rebirth. This has important implications for both restoration projects and de-extinction projects: we need to acknowledge the role of human design for restoration and conservation projects, and envision humans no longer as external and superior to eco-systems, but as part of them. Only within newly conceptualized social-ecological systems can such a new vision of physis take flight

Charisma and the Clinic

Here we argue that ‘charisma’, a concept widely taken up within geography and the environmental humanities, is of utility to the social studies of medicine. Charisma, we suggest, draws attention to the affective dimensions of medical work, the ways in which these affective relations are structured, and the manner in which they are intimately tied to particular material-discursive contexts. The paper differentiates this notion of charisma from Weber’s analyses of the ‘charismatic leader’ before detailing three forms of charisma - ecological (which relates to the affordances an entity has), corporeal (related to bodily interaction) and aesthetic (pertaining to an entity’s initial visual and emotional impact). Drawing on interview data we then show how this framework can be used to understand the manner in which psychologists and neuroscientists have come to see and act on autism. We conclude the article by suggesting that examining charisma within healthcare settings furthers the concept, in particular by drawing attention to the discursive features of ecologies and the ‘non-innocence’ of charisma

A wager on the future: a practicable response to HIV pre-exposure prophylaxis (PrEP) and the stubborn fact of process

In this article we focus on public health’s wager on the social implications of a daily antiretroviral pill to prevent HIV, referred to as PrEP (pre-exposure prophylaxis). The wager is shown to rely on modes of inquiry overly tied to what is known of the present in order to predict the future. Although such inquiry is not unusual when social research is called upon to assist health policy, predictive methodologies are unable to appreciate the dynamic and thus indeterminate nature of process. We ask: what mode of inquiry might practicably appreciate that what happens in the present will have a bearing on the future, without foreclosing on unknown possibles? Drawing on speculative and pragmatic philosophy, we reflect on our own qualitative research on PrEP to suggest that conventional methodological approaches can contribute to the future without seeking to determine what it will become

Affect, Relationality and the 'Problem of Personality'

This peer-reviewed journal article sets out an argument regarding the importance of genealogical work for understanding concepts such as affect and suggestion

Exploring the transdisciplinary trajectory of suggestibility

Traditionally considered a deficiency in will power and rationality, suggestibility has proven a troublesome concept for psychology. It was forgotten, rediscovered, denounced, undermined experimentation and recently became the ambiguous issue at the centre of concern about child witness' credibility in sexual abuse cases. This paper traces the history of suggestibility to show how it raises the 'paradox of the psychosocial'. Drawing on the work of Deleuze and Stengers, and on interviews with legal practitioners, this paper demonstrates how suggestibility carries this paradox into theory, research and legal practice. It thereby opens up a transdisciplinary perspective, allowing for questions of power and knowledge to be asked as performative questions. In the spirit of a process-centred ontology for psychology, I argue that suggestibility constitutes a 'rhythm of problematization', a folding, giving a subversive insight into dynamics of subjectification and application, and offering new perspectives towards issues of children's credibility and protection

Does dietary tocopherol level affect fatty acid metabolism in fish?

Fish are a rich source of the n-3 polyunsaturated fatty acids (PUFA), particularly the highly unsaturated fatty acids (HUFA), eicosapentaenoic (EPA; 20:5n-3) and docosahexaenoic (DHA; 22:6n-3) acids, which are vital constituents for cell membrane structure and function, but which are also highly susceptible to attack by oxygen and other organic radicals. Resultant damage to PUFA in membrane phospholipids can have serious consequences for cell membrane structure and function, with potential pathological effects on cells and tissues. Physiological antioxidant protection involves both endogenous components, such as free radical scavenging enzymes, and exogenous dietary micronutrients including tocopherols and tocotrienols, the vitamin E-type compounds, widely regarded as the primary lipid soluble antioxidants. The antioxidant activities of tocopherols are imparted by their ability to donate their phenolic hydrogen atoms to lipid (fatty acid) free radicals resulting in the stabilisation of the latter and the termination of the lipid peroxidation chain reaction. However, tocopherols can also prevent PUFA peroxidation by acting as quenchers of singlet oxygen. Recent studies on marine fish have shown correlations between dietary and tissue PUFA/tocopherol ratios and incidence of lipid peroxidation as indicated by the levels of TBARS and isoprostanes. These studies also showed that feeding diets containing oxidised oil significantly affected the activities of liver antioxidant defence enzymes and that dietary tocopherol partially attenuated these effects. However, there is evidence that dietary tocopherols can affect fatty acid metabolism in other ways. An increase in membrane PUFA was observed in rats deficient in vitamin E. This was suggested to be due to over production of PUFA arising from increased activity of the desaturation/elongation mechanisms responsible for the synthesis of PUFA. Consistent with this, increased desaturation of 18:3n-3 and 20:5n-3 in hepatocytes from salmon fed diets deficient in tocopherol and/or astaxanthin has been observed. Although the mechanism is unclear, tocopherols may influence biosynthesis of n-3PUFA through alteration of cellular oxidation potential or “peroxide tone”

Returning to Text: Affect, meaning making and literacies

Existing work on literacy and affect has posed important questions for how we think about meanings and how and where they get made. The authors contribute to such work by focusing on the relation between text and affect. This is a topic that has received insufficient attention in recent work but is of pressing concern for education as text interweaves in new ways with human activity, through social media, surveillance capitalism, and artificial intelligence—ways that can be unpredictable and poorly understood. Adopting a sociomaterial sensibility that foregrounds the relations between bodies (people and things), the authors provide conceptual tools for considering how texts affect and are affected by the heterogeneous entanglements from which they emerge. In situating their argument, the authors outline influential readings of Spinoza’s theories of affect, explore how these have been mobilized in literacy research, and identify how text has been accommodated within such research. Using texts from a political episode in the United Kingdom, the authors explore the idea of social-material-textual affects to articulate relationships among humans, nonhumans, meaning making, and literacies. The authors conclude by identifying four ways in which text participates in what happens, raising questions about how different materializations of text (or indeed “not text”) are significant to the diversifying communicative practices that inflect social, cultural, economic, and political life
