The Queer Ecology Of Clouds In Nineteenth-Century British Poetics, Lucien Darjeun Meadows

Electronic Theses and Dissertations

Throughout the nineteenth century, British writers were interested in the emergent science of meteorology, and their lyrical writing (their “poetics”), from poetry to creative and scientific prose, often turns to clouds as both meteorological formations and as material metaphors for human-environment interactions. These writers frequently invoke clouds to disrupt or “queer” depictions of human-environment relationships built on human domination of environmental beings. Clouds, in poetic writing, help writers (and readers) instead experience subject-subject relationships of reciprocity—a collaborative, non-hierarchical way of existing with and learning from our ecological relatives.

Dwelling in the confluence of literary studies, queer studies, and ecology, The …

Historical Realism And Stoic Heroes In The Work Of John Williams, Cameron Sepede

Electronic Theses and Dissertations

This thesis investigates how John Williams’s three major works of fiction — Butcher’s Crossing, Stoner, and Augustus — are narratively structured around three main characters who embody the tenets of stoic and Emersonian transcendental philosophy, respectively. Williams uses these characters to promote and critique preconceived notions of heroic masculinity as structured within these philosophies. Through an analysis of form, this thesis will explore how Williams scaffolds his three main characters around the language and ideas present within each philosophical school. Williams’s portrayal of heroic masculinity, as seen through a feminist perspective, questions the ideal masculine hero, which will be …
