Gödel, Escher, Bach is a complex exploration of self-reference, recursion, and formal systems, by the cognitive scientist Douglas Hofstadter. The book weaves together the work of mathematician Kurt Gödel, artist M. C. Escher, and composer Johann Sebastian Bach to show the interconnectedness of various disciplines in understanding the human mind and consciousness. Through intricate dialogues, Hofstadter explores concepts like paradoxes, symmetry, and the nature of thought. This work is a fascinating dive into logic, mathematics, art, and philosophy.
