Anyone who thinks Viv was nothing but a burden to TSE might find this passage striking, from the Intro to the suppressed essay:
"By Eliot’s own description, these lectures were intended as “further development of the problem which the author first discussed in his essay, ‘Tradition and the Individual Talent.’” A number of critics have also noted the fact that Eliot had recently separated from his wife Vivien, and without her steadying hand, these lectures reveal his complete transformation from aesthete to self-described “moralist.” ?
Reading this essay of Eliot's reinforces my sense that Sweeney Agonistes is a poetic exercise in intolerance. Sweeney is an Irish name, the other names might be Jewish, but in any case are not WASP names. At one point in the suppressed essay on personality and demonic possession, Eliot compares D.H. Lawrence's character of Mellors, the working class lover of Lady Chatterly, to savages. This brought to mind the cannibals in Sweeney Agonistes and their "missionary stew."
One cannot confine Eliot's social intolerance to anti-Semitism. He looked down his privileged nose at Others of all kinds: the poor, the uneducated, women, basically anyone not PLU (People Like Us).
Perhaps Vivienne reigned in his self-satisfied prejudices as the Intro above states. I find that a fascinating possibility.
