Reviews

"Sex At Dawn has helped me understand myself and the world so much more clearly." -- Ilana Glazer, co-creator of Broad City "Sex At Dawn is the single most important book about human sexuality since Alfred Kinsey unleashed Sexual Behavior in the Human Male on the American public in 1948." -- Dan Savage "Funny, witty, and light ... Sex at Dawn is a scandal in the best sense, one that will have you reading the best parts aloud and reassessing your ideas about humanity's basic urges well after the book is done." -- Newsweek "Sex At Dawn challenges conventional wisdom about sex in a big way... This is a provocative, entertaining, and pioneering book. I learned a lot from it and recommend it highly." -- Andrew Weil, M.D., author of Healthy Aging "Sex At Dawn is a provocative and engaging synthesis... that has the added benefit of being a joy to read... A book sure to generate discussion, and one likely to produce more than a few difficult conversations with family marriage counselors." -- Eric Michael Johnson, Seed Magazine "You clearly have an exciting book on your hands, whether people agree with it or not: these are issues that will need debating over and over before we will arrive at a resolution." -- Frans de Waal, author of The Age of Empathy "A wonderfully provocative and well-written book which completely re-evaluates human sexual behaviour and gets to the root of many of our social and psychological ills." -- Steve Taylor, author of The Fall and Waking From Sleep "One of the most original books I've read in years, Sex at Dawn manages to be both enormously erudite and wildly entertaining-even, frequently, hilarious... A must-read for anyone interested in where our sexual impulses come from." -- Tony Perrottet, author of Napoleon's Privates "This paradigm-shifting book is a thoroughly original discussion of the origins and nature of human sexuality... These authors have a gift for making complex material reader-friendly, filling each chapter with humor and passion as well as dozens of revolutionary insights." -- Stanley Krippner, Ph.D. "Christopher Ryan and Cacilda Jetha have written the essential corrective to the evolutionary psychology literature..." -- Stanton Peele, Ph.D.
