On December 5, 2004, the still-developing blogosphere took one of its biggest steps toward mainstream credibility, as Nobel Prize–winning economist Gary S. Becker and renowned jurist and legal scholar Richard A. Posner announced the formation of the Becker-Posner Blog.

In no time, the blog had established a wide readership and reputation as a reliable source of lively, thought-provoking commentary on current events, its pithy and profound weekly essays highlighting the value of economic reasoning when applied to unexpected topics. Uncommon Sense gathers the most important and innovative entries from the blog, arranged by topic, along with updates and even reconsiderations when subsequent events have shed new light on a question. Whether it’s Posner making the economic case for the legalization of gay marriage, Becker arguing in favor of the sale of human organs for transplant, or even the pair of scholars vigorously disagreeing about the utility of collective punishment, the writing is always clear, the interplay energetic, and the resulting discussion deeply informed and intellectually substantial.

To have a single thinker of the stature of a Becker or Posner addressing questions of this nature would make for fascinating reading; to have both, writing and responding to each other, is an exceptionally rare treat. With Uncommon Sense, they invite the adventurous reader to join them on a whirlwind intellectual journey. All they ask is that you leave your preconceptions behind.

The divide between teaching “intelligent design” and evolution in U.S. schools has brought to the public eye a struggle that archaeoastronomer Anthony Aveni argues is as old as culture itself. All societies seek to understand the natural world, but their search is shaped by culturally distinct views and experiences. In Uncommon Sense, Aveni explores the common and conflicting ways that ancient and contemporary societies have searched for the literal truth about the natural world’s mysteries, from dinosaur bones to the Star of Bethlehem. Aveni demonstrates that a society’s approach to making sense of the natural world can serve as a working definition of its culture, so strongly does it resonate with fundamental values and assumptions.

In ten fascinating essays, Aveni examines topics that have absorbed scientists, religious figures, and ordinary citizens over the centuries. He traces the tug of war between astronomy and astrology, reveals the underpinnings of our notions of cartography and the representation of space and time, and much more.

Readers interested in science, history, and world cultures will revel in this celebration of different cultures’ common and uncommon questions and conclusions about the natural world.
