Call it coincidence, call it destiny, but the first thing I encountered in my office last Friday morning, on returning from weeklong arbitration convenings in São Paulo, was Jeffrey Winn’s Law Journal review of the new book by Judge Richard Posner, “Reflections on Judging.” Immediately I spent my first “non-raies” (i.e., dollars) on the book, and am happily immersed in it. Good review.

The reviewer snared me in his opening paragraphs discussing Posner’s description of today’s challenge of “external complexities”—meaning systems external to the legal system that are unfamiliar to our overwhelmingly generalist federal judges, like modern scientific and technological complexities (facing, by the way, both state and federal courts).
