'Yes, the century is an ashen sun': poem and subject in the philosophy of Alain Badiou

This thesis examines the relation between philosophy, the poem and the subject in the mature philosophy of Alain Badiou. It investigates Badiou’s decisive contribution to these questions primarily by means of comparison, especially to Martin Heidegger, Philippe Lacoue-Labarthe and Theodor Adorno, as well as by analysing Badiou’s readings of poems and prose by Paul Celan and Samuel Beckett respectively as sites of potential dialogue with his immediate predecessors. The thesis stresses the importance of French philosophy’s German heritage, emphasising not only Badiou’s radical departure from Heidegger and his legacy, but also the former’s wholesale rejection of philosophies that would, in the wake of twentieth-century violence and beyond, proclaim their own end or completion. The thesis argues Badiou’s innovative readings of Celan and Beckett to be crucial to understanding this endeavour: for Badiou, both writers use the poem to affirm novel conceptions of subjectivity capable of transcending the historical conditions of their presentation. The title quotation from Badiou’s The Century, ‘Yes, the century is an ashen sun’, anticipates both the affirmative nature of these subjective figures, and their presience, beyond the bounds of a twentieth-century ‘ashen sun’ pervaded by melancholy, for the ‘new suns’ of the twenty-first. The thesis is in four chapters. The first chapter unfolds the central concepts of Badiou’s departure from Heidegger using Paul Celan’s poems to focus the enquiry. It is guided by two of Badiou’s most condensed declarations about the poem, that, firstly, ‘the modern poem harbours a central silence’, and secondly, that ‘Celan completes Heidegger’. The second chapter exposes the political implications of Heidegger’s writings on Friedrich Hölderlin and the role of the subject therein, offering at its close some thoughts about what Badiou calls, following Philippe Lacoue-Labarthe, the poem’s ‘becoming-prose’. It concludes by drawing the poem and politics into relation by way of the philosophical category of the subject. The third chapter reads Badiou’s concept of ‘anabasis’ against Heidegger’s ‘homecoming’ in order to think the possibility of a collective political subject’s formation in the wake of Auschwitz. The final chapter examines the imbrication of the Two of love and the ‘latent poem’ in Badiou’s reading of Samuel Beckett’s late prose, contrasting this ‘affirmative’ reading of Beckett to Theodor Adorno’s earlier emphases on negation. Following its investigations of subjectivity, poem and prose throughout, the thesis concludes by returning to the title quotation in order to unfold the particular relations between subject, affirmation and negation Badiou’s philosophy enacts, and to offer further routes forward for research regarding Badiou’s philosophy and aesthetic figuration.

From physics to metaphysics: philosophy and style in the critical writings of T. S. Eliot (1913-1935)

This thesis considers Eliot's critical writing from the late 1910s till the mid-1930s, in the light of his PhD thesis - Knowledge and Experience in the Philosophy of F. H. Bradley - and a range of unpublished material: T S. Eliot's Philosophical Essays and Notes (1913- 4) in the Hayward Bequest (King's College, Cambridge University); T. S. Eliot's Family Papers in the T. S. Eliot Collection at the Houghton Library (Harvard University); and items from the Harvard University Archives at the Pusey Library. 'Me thesis offers a comprehensive view of Eliot's critical development throughout this important period. It starts by considering The Sacred Wood's ambivalence towards the metaphysical philosophy of F. H. Bradley and Eliot's apparent adoption of a scientific method, under the influence of Bertrand Russell. It will be argued that Eliot uses rhetorical strategies which simultaneously subvert the method he is propounding, and which set the tone for an assessment of his criticism throughout the 1920s. His indecision, in this period, about the label 'Metaphysical' for some poets of the seventeenth century, reveals the persistence of the philosophical thought he apparently rejects in 1916, when he chooses not to pursue a career in philosophy in Harvard. This rhetorical tactic achieves its fulfilment in Dante (1929), where Eliot finds a model in the medieval allegorical method and 'philosophical' poetry. Allegory is also examined in connection with the evaluation of Eliot's critical writings themselves to determine, for instance, the figurative dimension of his early scientific vocabulary and uncover metaphysical residues he had explicitly disowned but would later embrace. Finally, it is suggested that, the hermeneutics of allegory are historical and it is used here to test the relationship between Eliot's early and later critical writings, that is the early physics and the later metaphysics.

The role of oxidative stress as an underlying mechanism in life-history trade-offs

A key aspect underpinning life-history theory is the existence of trade-offs. Trade-offs occur because resources are limited, meaning that individuals cannot invest in all traits simultaneously, leading to costs for traits such as growth and reproduction. Such costs may be the reason for the sub-maximal growth rates that are often observed in nature, though the fitness consequences of these costs would depend on the effects on lifetime reproductive success. Recently, much attention has been given to the physiological mechanism that might underlie these life-history trade-offs, with oxidative stress (OS) playing a key role. OS is characterised by a build-up of oxidative damage to tissues (e.g. protein, lipids and DNA) from attack by reactive species (RS). RS, the majority of which are by-products of metabolism, are usually neutralised by antioxidants, however OS occurs when there is an imbalance between the two. There are two main theories linking OS with growth and reproduction. The first is that traits like growth and reproduction, being metabolically demanding, lead to an increase in RS production. The second involves the diversion of resources away from self-maintenance processes (e.g. the redox system) when individuals are faced with enhanced growth or reproductive expenditure. Previous research investigating trade-offs involving growth or reproduction and self-maintenance has been equivocal. One reason for this could be that associations among redox biomarkers can vary greatly so that the biomarker selected for analysis can influence the conclusion reached about an individual’s oxidative status. Therefore the first aim of my thesis was to explore the strength and pattern of integration of five biomarkers of OS (three antioxidants, one damage and one general oxidation measure) in wild blue tit (Cyanistes caeruleus) adults and nestlings (Chapter 2). In doing so, I established that all five biomarkers should be included in future analyses, thus using this collection of biomarkers I explored my next aims; whether enhanced growth (Chapters 3 and 4) or reproductive effort (Chapter 5) can lead to increased OS levels, if these traits are traded off against self-maintenance. I accomplished these aims using both a meta-analytic and experimental approach, the latter involving manipulation of brood size in wild blue tits in order to experimentally alter growth rate of nestlings and provisioning rate (a proxy for reproductive expenditure) of adults. I also investigated the potential for redox integration to be used as an index of body condition (Chapter 2), allowing predictions about future fitness consequences of changes to oxidative state to be made. A growth – self-maintenance trade off was supported by my meta-analytic results (Chapter 4) which found OS to be a constraint on growth. However, when faced with experimentally enhanced growth, animals were typically not able to adjust this trade-off so that oxidative damage resulted. This might support the idea that energetically expensive growth causes resources to be diverted away from the redox system; however, antioxidants did not show an overall reduction in response to growth in the meta-analysis suggesting that oxidative costs of growth may result from increased RS production due to the greater metabolism needed for enhanced growth. My experimental data (Chapter 3) showed a similar pattern, with raised protein damage levels (protein carbonyls; PCs) in the fastest growing blue tit chicks in a brood, compared with their slower growing sibs. These within-brood differences in OS levels likely resulted from within-brood hierarchies and might have masked any between-brood differences, which were not observed here. Despite evidence for a growth – self-maintenance trade off, my experimental results on blue tits found no support for the hypothesis that self-maintenance is also traded off against reproduction, another energetically demanding trait. There was no link between experimentally altered reproductive expenditure and OS, nor was there a direct correlation between reproductive effort and OS (Chapter 5). However, there are various factors that likely influence whether oxidative costs are observed, including environmental conditions and whether such costs are transient. This emphasises the need for longitudinal studies following the same individuals over multiple years and across a wide range of habitats that differ in quality. This would allow investigation into how key life events interact; it might be that raised OS levels from rapid early growth have the potential to constrain reproduction or that high parental OS levels constrain offspring growth. Any oxidative costs resulting from these life-history trade-offs have the potential to impact on future fitness. Redox integration of certain biomarkers might prove to be a useful tool in making predictions about fitness, as I found in Chapter 2, as well as establishing how the redox system responds, as a whole, to changes to growth and reproduction. Finally, if the tissues measured can tolerate a given level of OS, then the level of oxidative damage might be irrelevant and not impact on future fitness at all.
