The double entendre of "goes to his head" in that quotation is pretty amazing — it has both descriptive meaning as something of which intellectualizing occurs and also contrasts the heart and the ego, suggesting that the ego sits in the intellect. Very good. What I'm getting at here is that this idea of Mandela's also applies to samewise monolingual speakers — as we each have our own idiolect, so far as descriptivist linguists are concerned. Double very good.
