"Ignorance might seem to be a pressing contemporary problem but, as this dazzling, comprehensive book shows, it has many pasts. Only Peter Burke could have written such a deliciously knowledgeable history of ignorance."—David Armitage, Civil Wars: A History in Ideas
"A rich, fascinating book of astonishing range. Burke impresses the need for awe and humility about how much humanity doesn’t know or refuses to know, and how this problem shifts and resurfaces across eras."—Linsey McGoey, author of The Unknowers
"Delivers a journey through all forms of not knowing, from secrecies to unintended consequences, to different forms of forgetting things formerly known. Burke shows that as more knowledge is generated, the horizon of ignorance can widen – for good or for bad. Burke’s new book will not only be a milestone in ignorance studies, but should become standard reading."—Matthias Gross, author of Ignorance and Surprise
