The current issue of Comparative and Continental Philosophy (issue 7:2) has some excellent, provocative material on the methodology of comparative philosophy. I particularly recommend:

• Amy K. Donahue & Rohan Kalyan, “Introduction: On the Imperative, Challenges, and Prospects of Decolonizing Comparative Methodologies”

and

• David Haekwon Kim, “José Mariátegui’s East-South Decolonial Experiment”
