It鈥檚 a story we can鈥檛 stop telling ourselves. Once, humans were benighted by superstition and irrationality, but then the Greeks invented reason. Later, the Enlightenment enshrined rationality as the supreme value. Discovering that reason is the defining feature of our species, we named ourselves the 鈥渞ational animal.鈥� But is this flattering story itself rational? In this sweeping account of irrationality from antiquity to today鈥攆rom the fifth-century BC murder of Hippasus for revealing the existence of irrational numbers to the rise of Twitter mobs and the election of Donald Trump鈥擩ustin Smith says the evidence suggests the opposite. From sex and music to religion and war, irrationality makes up the greater part of human life and history.
Rich and ambitious, Irrationality ranges across philosophy, politics, and current events. Challenging conventional thinking about logic, natural reason, dreams, art and science, pseudoscience, the Enlightenment, the internet, jokes and lies, and death, the book shows how history reveals that any triumph of reason is temporary and reversible, and that rational schemes, notably including many from Silicon Valley, often result in their polar opposite. The problem is that the rational gives birth to the irrational and vice versa in an endless cycle, and any effort to permanently set things in order sooner or later ends in an explosion of unreason. Because of this, it is irrational to try to eliminate irrationality. For better or worse, it is an ineradicable feature of life.
Illuminating unreason at a moment when the world appears to have gone mad again, Irrationality is fascinating, provocative, and timely.

"Irrationality is . . . stippled with fascinating meditations and vignettes."鈥擪wame Anthony Appiah, New York Review of Books
"Irrationality is unique among recent paeans to Enlightenment and liberalism in marrying a resolute defence of reason with a recognition of how futile such defences tend to be. As Smith expertly reveals, wherever one looks in the history of Western philosophy, rationality is haunted and teased by its other."鈥擶illiam Davies, London Review of Books
"Smith is an excellent dramatizer of this dialectic, a witty and provocative guide leading the reader through chapters on logic . . . pseudoscience . . . and death . . . with a distinctive voice and considerable wit."鈥擩onathan Egid, Times Literary Supplement
"No philosopher alive today writes with as much wit, voice, and erudition as Justin Smith. Irrationality is a masterpiece: an urgent warning that no grand design of perfect rationality can provide the solution to the depravity of this political moment."鈥擸ascha Mounk, author of The People vs. Democracy: Why Our Freedom Is in Danger and How to Save It
鈥淛ustin Smith's book could not have come at a better moment. In an era in which many have taken leave of their senses, he draws a map of what led us here, offering a convincing account of the Enlightenment and its discontents. The passages on Trumpism are particularly edifying.鈥濃�擟hristy Wampole, author of The Other Serious: Essays for the New American Generation
鈥淲ith a vast sweep and elegant writing, this is a remarkable, erudite, and stylish book on an important and timely subject: the persistent tendency toward irrationalism in human history. Irrationality is fresh, perceptive, and enjoyable.鈥濃�擪ieran Setiya, author of Midlife: A Philosophical Guide
"A learned, ludic, and often profound meditation on how the perverse dialectic of reason and unreason has played out over history, from the era of Pythagoras to that of 沤i啪ek and Trump. Smith writes with the limpidity of an anglophone philosopher and the cool encyclopedic assurance of a Parisian intello."鈥擩im Holt, author of Why Does the World Exist? An Existential Detective Story
