The Scrapbook is a Johnny-one-note when it comes to our favorite quarterly, National Affairs: It’s great. The Spring 2014 issue arrived on our desk this week, and as usual editor Yuval Levin has assembled a winning lineup. Jim Manzi’s essay on what he calls “the new American system of innovation” is alone worth the price of admission. Diana Schaub writes beautifully on “Lincoln at Gettysburg.” And in between these two masterful essays are an assortment of policy articles that will more than repay your time and attention.
