As he's investigated the far-right and the Church i'll assume his politics lean to the left; as he's French, and a French intellectual at that, i'd say he's Communist. Or at least, a Communard, in the French tradition. If he drinks strong coffee in small cups and smokes Gitanes then he's probably read Sartre for fun - i was drawn to the link by 'Voltaire', so if that's his inspiration then i'm prepared to hear him out: I've read Candide inside out since college and "All's for the best in the best of all possible worlds" still has meaning in today's world.
So link me up, Scotty.
