In my last column, I talked about the challenges and excitements of tackling ancient Indian philosophy in my History of Philosophy podcast – thankfully with the help of an expert, Jonardon Ganeri. We’ve already received some feedback about the series, young though it is.

Is Buddhism a religious tradition, or a philosophical tradition? Are the Upanisads really philosophical texts?
