I spend a lot of time listening to rubbish interviews to find the quality ones and this one certainly makes the grade. Dr Farrell has a PhD in Patristics from Oxford so his approach to disentangling history includes theology, metaphysics, physics, history, languages and much much more.
His thesis may not be correct but it is coherent and forces the reader or listener to look at ancient questions in new ways which is as good as it gets for me.
