Economic Development in Texas During Reconstruction, 1865-1875

Description: The study challenges many traditional stereotypes of Texas during Reconstruction. Contrary to what Democrats charged, the Davis government did not levy exorbitant taxes.

Radical taxes constituted only 1.77 percent of the assessed value of property in Texas, which was lower than the average for the… more

"Looking into the Heart of Light, the Silence": The Rule of Desire in T.S. Eliot's Poetry

Description: The poetry of T. S. Eliot represents intense yet discriminate expressions of desire. His poetry is a poetry of desire that extenuates the long tradition of love poetry in Occidental culture. The unique and paradoxical element of love in Occidental culture is that it is based on an ideal of the unconsummated love relationship between man and woman. The struggle to express desire, yet remain true to ideals that have deep sacred and secular significance is the key animating factor of Eliot's poetr… more

T. S. Eliot's Ash Wednesday: a Philosophical Approach to Empowering the Feminine

Description: In his 1916 dissertation, Eliot asserted that individuals were locked into finite centers and that all knowledge was epistemologically relative, but he also believed that finite centers could be transcended through language. In the essay "Lancelot Andrewes,'" Eliot identified Andrewes's "relevant intensity," a method very close to nonsensical verse. Eliot used Andrewes's Word and the impersonality of nonsense verse in Ash Wednesday. The Word, God's logos, embodied the Virgin Mary as its source,… more
