Who makes better foreign policy: artists or scientists?

There are books that are read and books that are admired, and they are not necessarily the same books. “Worldmaking,” by David Milne, seems destined to be more admired than read. Its subject alone tends to induce a respectful but glazed silence. If the topic is intellectually hefty, the book itself is heftier still (it weighs in at more than 500 pages of text), and the print is so small that readers over 40 would do well to keep their magnifying glasses handy.
