These ideas are very much reflected in Zen and the Art of Motorcycle Maintenance.

What enters your mind and goes through a function of complete rational cognition- cannot be the ultimate truth.

And we repeatedly see in Zen koans, also mentioned in GEB, and life and teachings of Buddha that all questions cannot be purely answered with mere words.

Tractatus, Godel's Incompleteness, Halting problem, and these all somehow talk about the same unknowability- or at least intellectually.
