Kalman has taken 'the little book' [The Elements of Style] and made it even more elegant and uplifting." -- Los Angeles Times "While The Elements of Style has never lacked fans or dutiful adherents, appreciation for this slim volume has taken a turn toward the whimsical and even surreal." -- New York Times "The pictures are playful and subtle, which suits the spirit of the beloved bestseller [The Elements of Style]." -- USA Today "My absolute favorite book of recent memory: an exquisite and delightful and peculiarly illustrated memoir about ... well, the search for the meaning of life. I will be giving this book [The Principles of Uncertainty] to everyone I love." -- Elizabeth Gilbert, author of Eat, Pray, Love
