I did not reference linguistics literature, but philosophy literature (a distinction worth making because they are approaching the problem at different levels). I've never been good at the 'language problem' elevator speech, but how is it possible that we can capture the full power of language while using language to describe it? Language is a technology that allows for the production of concepts like 'probability' or 'apple'. Language as a tool is so fundamental to cognition that it becomes difficult to separate the two. Heidegger's Being and Time explores that line of thinking, and Derrida loves to play the game of "well that means you can't say anything!" Both have provided me with insight into what "magic" is referencing here (rather than your fairly pithy absence-of-evidence reference).
