Inspired by a hatred of Heidegger, more likely--at least from the few excerpts by TB Ive read. Not sure of his views on St.Witt (or MH's--tho' I doubt Vati H. cared for him or his philosophy much).
I've read that academic philosophy in Iran is split into Heideggerian and Popperian factions. I expect the Popperians read the Tractatus. Not sure which factions reads Philosophical Investigations.
