Supreme Court nominee Neil Gorsuch isn’t just a respected judge; he also holds a philosophy degree from Oxford, where he studied under John Finnis, one of the most prominent scholars in natural law theory. That may seem arcane, but Gorsuch’s views about natural law set him apart from colleagues on the bench—and those differences matter, writes Timothy Sandefur. And they don’t just matter to liberals; they matter to conservatives and libertarians, too.
