A point to remember here is that rather than a judgment upon Russell's philosophy, Eliot is striking at the man. Vivien unfortunately had a mental illness which compounded the problems in their relationship, only for Russell to take sexual advantage of her.

Eliot was a newly converted Catholic at the time, yes, with a renewed religious insight, but clear in his thinking and erudition. Without his intellect and vision, the construction of The Waste Land would not have been possible

Russell - Celebrated thinker, fuck of a human being.
