In Understanding Pain, Fernando Cervero explores the mechanisms and the meaning of pain. You touch something hot and your brain triggers a reflex action that causes you to withdraw your hand, protecting you from injury. That kind of pain, Cervero explains, is actually good for us; it acts as an alarm that warns us of danger and keeps us away from harm. But nt all pain is good for you. There is another kind of pain that is more like a curse: chronic pain that is not related to injury. This is the kind of pain that fills pain clinics and makes life miserable.

In The Story of America, Harvard historian and New Yorker staff writer Jill Lepore investigates American origin stories - from John Smith's account of the founding of Jamestown in 1607 to Barack Obama's 2009 inaugural address - to show how American democracy is bound up with the history of print. Over the centuries, Americans have read and written their way into a political culture of ink and type. Part civics primer, part cultural history, The Story of America excavates the origins of everything from the paper ballot and the Constitution to the I.O.U. and the dictionary.

Are mass violence and catastrophes the only forces that can seriously decrease economic inequality? To judge by thousands of years of history, the answer is yes. Tracing the global history of inequality from the Stone Age to today, Walter Scheidel shows that inequality never dies peacefully. Inequality declines when carnage and disaster strike and increases when peace and stability return. The Great Leveler is the first book to chart the crucial role of violent shocks in reducing inequality over the full sweep of human history around the world.
