If you ask anyone what colleges and universities are for, they'll give you more or less the same answer: to educate people.  That's a good answer. It's the one I give myself. But it's only half the truth. Colleges and universities actually fulfill two separate roles. We all know about both of them. We only talk about one of them. And because of that, we misunderstand almost everything about how higher education works and how it might be improved.

Five weeks after a terrorist attack on Boston, President Obama has declared that the War on Terror, "like all wars, must end."  If I had told you a year ago that he would make such a speech a month and a half after a high-profile terrorist attack on a major American city, neither you nor I would have believed me. But the lessons of Boston drive home the wisdom of the President's decision. It showed us that a terrorist attack is meant to be lived through and that Americans are ready to live through one.

It's been a tough week for elite gay-baiting. First Howie Kurtz, hack journalist extraordinaire, lost his job at the Daily Beast because he badly botched an attempt to smear NBA center Jason Collins. Part of what Kurtz botched was the facts, claiming that Collins had concealed the fact that he had once been engaged to a woman when Collins had "concealed" that fact by explicitly stating it in his Sports Illustrated coming-out article. ("When I was younger I dated women. I even got engaged," is pretty straightforward.) Kurtz, to his credit, has made a full apology.

Then, Harvard history professor Niall Ferguson (also a columnist for the Daily Beast) was also forced to apologize after publicly gay-baiting landmark economist John Maynard Keynes. Ferguson decided to tell an audience that Keynes wasn't interested in long-term policy effects (itself a gross distortion of Keynes's position) because Keynes was a homosexual in a childless marriage. Yes, really. That's the standard of logic and evidence to which Ferguson holds himself.

Boston is my home, my beloved city, although I have not lived there for many years. And Patriot's Day, the Monday of the Boston Marathon, is the proudest day in a proud city's year. We open our city to all, and hold one of the world's greatest sporting events, the oldest annual marathon on the globe. We hold that race in public streets and fill the sidewalks to cheer. It is Boston's day to celebrate the many things that make it Boston.
