"In short, Life Is Simple is enthralling."–Michael Blastland, Prospect

A biologist argues that simplicity is the guiding principle of the universe

 
Centuries ago, the principle of Ockham’s razor changed our world by showing simpler answers to be preferable and more often true. In Life Is Simple, scientist Johnjoe McFadden traces centuries of discoveries, taking us from a geocentric cosmos to quantum mechanics and DNA, arguing that simplicity has revealed profound answers to the greatest mysteries. This is no coincidence. From the laws that keep a ball in motion to those that govern evolution, simplicity, he claims, has shaped the universe itself. And in McFadden’s view, life could only have emerged by embracing maximal simplicity, making the fundamental law of the universe a cosmic form of natural selection that favors survival of the simplest. Recasting both the history of science and our universe’s origins, McFadden transforms our understanding of ourselves and our world.

Praise

“In a conspiracy-laden world, McFadden’s argument, that simple explanations hold true, will appeal to historians and the scientifically minded.”
 —Library Jounal
“thoroughly fascinating . . . breath-taking in its comprehensiveness and clarity”—The Irish Times
If you are at all interested in the history of ideas, this is a fabulous read. Even after you’ve taken a few detours through other material to become better oriented in the controversy over what exactly he’s good for, William plausibly still stands as a daring, original figure who deserves a place in the Pantheon, and McFadden has done a great service in bringing the whole William and his influence to wider attention. In short, Life Is Simple is enthralling. —Michael Blastland, Prospect (UK)
"The most sheerly enjoyable history of science of recent years."—Simon Ings, The Spectator (UK)
“In LIFE IS SIMPLE, geneticist Johnjoe McFadden offers a breezy but well-researched look at how the razor has inspired some of science’s biggest ideas…his examples illustrate with persuasive power how ‘simplicity continues to present us with the most profound, enigmatic and sometimes unsettling insights’ into how the universe works.” 
 —Scientific American
With flair and accessibility, McFadden walks readers through Occam’s many intellectually revolutionary ideas...A dense, provocative, and satisfying foray into the history of science.”—Kirkus Reviews
“A compelling assessment of an idea many of us know but few deeply understand.”—John Keogh, Booklist
“Occam’s razor, like Hobson’s choice and Schrödinger’s cat, is a phrase that’s entered the language. We know more or less what it means without necessarily knowing anything about its inventor or realising the immense power it has as a philosophical and scientific principle. LIFE IS SIMPLE describes brilliantly the context in which William of Occam lived and worked, and the transforming effect that his simple-seeming doctrine has had on the development of our understanding of nature and the universe."—Philip Pullman, author of the His Dark Materials trilogy
“Original and profound.”
 —Jim al-Khalili, author of The World According to Physics and Life on the Edge
“I found myself captured by the central premise: science, though perceived as complicated, is actually the pursuit of simplicity. The world is currently waking up to the complexities of science and its role in our world, and this book is an enlightening aid to that new understanding."—Michael Brooks, author of 13 Things that Don’t Make Sense
