An absolutely fascinating article about language and how it could be tied to consciousness and human evolution (cultural and otherwise).
I've been reading Hofstadter's Gödel, Escher & Bach lately (yeah yeah, I know, stereotypical much) and this article has a lot of interesting themes that tie into it. Self-as-illusion and self-as-self-reference seem to be really high on my "(positive) shit that keeps me up at night" list
