A friend and I once did an 8-day walk in the north of England. Much of our second day’s walk was done in view of Dunstanburgh Castle, a giant 14th-century fort now in ruins. The castle was built by Thomas, Earl of Lancaster, with a purpose: to declare Thomas’ wealth and glory. In many ways he succeeded. Seven centuries later, the castle keeps Thomas’ name alive. But in the most important sense he failed. A sign in front of the castle remembers Thomas as an “arrogant and unpopular” man.
