William Eggington 
The Rigor of Angels [EPUB ebook] 
Borges, Heisenberg, Kant, and the Ultimate Nature of Reality

A poet, a physicist, and a philosopher explore the greatest enigmas of the universe in this scintillatingly original book about the limits of human knowledge
__________
'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, Wall Street Journal
'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

Argentine poet Jorge Luis Borges was madly in love when his life was shattered by painful heartbreak. But the breakdown that followed illuminated an incontrovertible truth-that love is necessarily imbued with loss, that the one doesn't exist without the other.
German physicist Werner Heisenberg was fighting with the scientific establishment on the meaning of the quantum realm's absurdity when he had his own epiphany-that there is no such thing as a complete, perfect description of reality.
Prussian philosopher Immanuel Kant pushed the assumptions of human reason as far as they could go, concluding that the human mind has fundamental limits, and those limits undergird both our greatest achievements as well as our missteps.
Through fiction, science, and philosophy, the work of these three thinkers coalesced around the powerful, haunting fact that there is an irreconcilable difference between reality 'out there’ and reality as we experience it. In this soaring, lucid reflection on the lives of Borges, Heisenberg and Kant, William Egginton profoundly demonstrates the enduring mystery of the world, and our place within it.
