Chaucer and the Disconsolations of Philosophy: Boethius, Agency, and Literary Form in Late Medieval Literature

This study argues that Chaucer's poetry belongs to a far-reaching conversation about the forms of consolation (philosophical, theological, and poetic) that are available to human persons. Chaucer's entry point to this conversation was Boethius's Consolation of Philosophy, a sixth-century dialogue that tried to show how the Stoic ideals of autonomy and self-possession are not simply normative for human beings but remain within the grasp of every individual. Drawing on biblical commentary, consolation literature, and political theory, this study contends that Chaucer's interrogation of the moral and intellectual ideals of the Consolation took the form of philosophical disconsolations: scenes of profound poetic rupture in which a character, sometimes even Chaucer himself, turns to philosophy for solace and yet fails to be consoled. Indeed, philosophy itself becomes a source of despair. In staging these disconsolations, I contend that Chaucer asks his readers to consider the moral dimensions of the aspirations internal to ancient philosophy and the assumptions about the self that must be true if its insights are to console and instruct. For Chaucer, the self must be seen as a gift that flowers through reciprocity (both human and divine) and not as an object to be disciplined and regulated.

Chapter one focuses on the Consolation of Philosophy. I argue that recent attempts to characterize Chaucer's relationship to this text as skeptical fail to engage the Consolation on its own terms. The allegory of Lady Philosophy's revelation to a disconsolate Boethius enables philosophy to become both an agent and an object of inquiry. I argue that Boethius's initial skepticism about the pretentions of philosophy is in part what Philosophy's therapies are meant to respond to. The pressures that Chaucer's poetry exerts on the ideals of autonomy and self-possession sharpen one of the major absences of the Consolation: viz., the unanswered question of whether Philosophy's therapies have actually consoled Boethius. Chapter two considers one of the Consolation's fascinating and paradoxical afterlives: Robert Holcot's Postilla super librum sapientiae (1340-43). I argue that Holcot's Stoic conception of wisdom, a conception he explicitly links with Boethius's Consolation, relies on a model of agency that is strikingly similar to the powers of self-knowledge that Philosophy argues Boethius to posses. Chapter three examines Chaucer's fullest exploration of the Boethian model of selfhood and his ultimate rejection of it in Troilus and Criseyde. The poem, which Chaucer called his "tragedy," belonged to a genre of classical writing he knew of only from Philosophy's brief mention of it in the Consolation. Chaucer appropriates the genre to explore and recover mourning as a meaningful act. In Chapter four, I turn to Dante and the House of Fame to consider Chaucer's self-reflections about his ambitions as a poet and the demands of truth-telling.

Multiple Dynamic Processes Contribute to the Complex Steady Shear Behavior of Cross-Linked Supramolecular Networks of Semidilute Entangled Polymer Solutions.

Molecular theories of shear thickening and shear thinning in associative polymer networks are typically united in that they involve a single kinetic parameter that describes the network -- a relaxation time that is related to the lifetime of the associative bonds. Here we report the steady-shear behavior of two structurally identical metallo-supramolecular polymer networks, for which single-relaxation parameter models break down in dramatic fashion. The networks are formed by the addition of reversible cross-linkers to semidilute entangled solutions of PVP in DMSO, and they differ only in the lifetime of the reversible cross-links. Shear thickening is observed for cross-linkers that have a slower dissociation rate (17 s(-1)), while shear thinning is observed for samples that have a faster dissociation rate (ca. 1400 s(-1)). The difference in the steady shear behavior of the unentangled vs. entangled regime reveals an unexpected, additional competing relaxation, ascribed to topological disentanglement in the semidilute entangled regime that contributes to the rheological properties.

Wee1-regulated apoptosis mediated by the crk adaptor protein in Xenopus egg extracts.

Many of the biochemical reactions of apoptotic cell death, including mitochondrial cytochrome c release and caspase activation, can be reconstituted in cell-free extracts derived from Xenopus eggs. In addition, because caspase activation does not occur until the egg extract has been incubated for several hours on the bench, upstream signaling processes occurring before full apoptosis are rendered accessible to biochemical manipulation. We reported previously that the adaptor protein Crk is required for apoptotic signaling in egg extracts (Evans, E.K., W. Lu, S.L. Strum, B.J. Mayer, and S. Kornbluth. 1997. EMBO (Eur. Mol. Biol. Organ.) J. 16:230-241). Moreover, we demonstrated that removal of Crk Src homology (SH)2 or SH3 interactors from the extracts prevented apoptosis. We now report the finding that the relevant Crk SH2-interacting protein, important for apoptotic signaling in the extract, is the well-known cell cycle regulator, Wee1. We have demonstrated a specific interaction between tyrosine-phosphorylated Wee1 and the Crk SH2 domain and have shown that recombinant Wee1 can restore apoptosis to an extract depleted of SH2 interactors. Moreover, exogenous Wee1 accelerated apoptosis in egg extracts, and this acceleration was largely dependent on the presence of endogenous Crk protein. As other Cdk inhibitors, such as roscovitine and Myt1, did not act like Wee1 to accelerate apoptosis, we propose that Wee1-Crk complexes signal in a novel apoptotic pathway, which may be unrelated to Wee1's role as a cell cycle regulator.
