All you ever wanted to know about G¶del

Both interviews are wonderfully clear.
A favorite bit of Hofstadter

Moreover, Gödel’s construction revealed in a crystal-clear way that the line between “direct” and “indirect” self-reference (indeed, between direct and indirect reference, and that’s even more important!) is completely blurry, because his construction pinpoints the essential role played by isomorphism (another name for coding) in the establishment of reference and meaning. Gödel’s work is, to me, the most beautiful possible demonstration of how meaning emerges from and only from isomorphism, and of how any notion of “direct” meaning (i.e., codeless meaning) is incoherent. In brief, it shows that semantics is an emergent quality of complex syntax, which harks back to my earlier remark in the Post Scriptum to Chapter 1, namely: “Content is fancy form.”
