The Rigor of Angels: Borges, Heisenberg, Kant, and the Ultimate Nature of Reality

⚖The case for it

A physicist compromising himself under the Nazis, a philosopher who never left Konigsberg, and a blind librarian in love with infinity all hit the same wall: the observer can never step outside the observation. One reader says the book "picks brains of great thinkers millenniums apart and proves fundamental incompleteness of our understanding," and the braid holds because "Egginton has a gift for distillation," as one critic puts it: Kant's antinomies, Heisenberg's uncertainty, and Borges's Aleph end up explaining each other. A doctoral student who grabbed it as a break from her dissertation says "It will make you believe in the power of the humanities again," and readers shelve it with the great atomic histories, "one of the most enjoyable I've read since The Making of the Atomic Bomb."

✕The case against

Check the title: Borges gets top billing, then shows up for two short stories and a tour of his romances ("Borges was hardly used, except for two short stories, and more time was spent unnecessarily on his love life," one reader says). That thinness is the pattern: three thinkers splitting one book three ways means "the analysis of each is repetitive and superficial," and when the physics finally arrives it does not clarify anything, "the explication of their insights becomes long-winded to the point of confusion." The whole load-bearing beam, Kant somehow anticipating quantum mechanics, buckles as soon as a working physicist leans on it: "Immanuel Kant did not know about quantum mechanics."
