After Alice Walker’s “In Search of Our Mothers’ Gardens” was published, there was a mini explosion of womanist writings, mostly with a theological (Christian) bent. Emilie Townes, Jacquelyn Grant, Cheryl Kirk-Duggan, Kelly Brown Douglas are a few of the people who have continued to flesh out womanist theory. “A Troubling in My Soul: Womanist Perspectives on Evil and Suffering,” edited by Townes is a nice intro to the field if you’re interested.
