The Problem with Knowing Everything

The title character of “Funes the Memorious,” a short story by Argentine writer Jorge Luis Borges, suffers a head injury that renders him incapable of forgetting even the smallest detail. Forced to perceive everything at every moment in sharp relief, Funes grieves the ability to experience the world, as others do, in abstractions.

This story of the “perfect observer” helped author William Egginton better understand German physicist Werner Heisenberg’s principles that helped lay the foundations of quantum mechanics. It also inspired Egginton to write a book exploring the nature of reality and the different ways humans grasp it through the lenses of three great thinkers: Borges, Heisenberg, and Prussian philosopher Immanuel Kant.

At a Harvard Science Book Talk on “The Rigor of Angels: Borges, Heisenberg, Kant, and the Ultimate Nature of Reality,” Egginton was joined by Homi K. Bhabha, the Anne F. Rothenberg Professor of the Humanities. Their conversation kicked off with Egginton reflecting on the book’s themes, including metaphysics, ethics, and cosmopolitanism.
