'Mind-expanding... Elegantly written... explores nothing less than "the ultimate nature of reality"... This is a book about the tiniest of things - the position of an electron, an instant of change. It is also about the biggest of things - the cosmos, infinity, the possibility of free will' - New York Times

'A remarkable synthesis of the thoughts, ideas, and discoveries of three of the greatest minds that our species has produced. The richness of the book cannot be fully acknowledged in the space of a review. Mr. Egginton advances a great many knotty arguments and propositions, but he is never less than exciting, provocative, and illuminating.' - John Banville

'In this sprightly intellectual history, Egginton explores the lives of the philosopher Immanuel Kant, the writer Jorge Luis Borges, and the physicist Werner Heisenberg in order to plumb some of the most profound questions of physics and philosophy: the limits of knowledge, the structure of space and time, free will' - New Yorker

'A fascinating reflection!' - Carlo Rovelli, author of 'The Order of Time'

'A book of tremendous intelligence and beauty. William Egginton makes the paradoxes of physics, metaphysics, and literature intelligible by showing how these paradoxes shape the limits of the visible world and the possibilities of the invisible one.' - Merve Emre
