Members of the Class of 2014, I salute you. My warmest wishes on the occasion of your graduation from this fine institution. And, before I go any further, I would like to express my personal thanks to all of you for not rescinding my invitation. I know that matters were dicey for a while, given that I have held and defended actual positions on politically contested issues.

Now and then I've strayed from the party line. And if the demonstrators would quiet down for a moment, I'd like to offer an abject apology for any way in which I have offended against the increasingly narrow and often obscure values of the academy.

In my day, the college campus was a place that celebrated the diversity of ideas. Pure argument was our guide. Staking out an unpopular position was admired — and the admiration, in turn, provided excellent training in the virtues of tolerance on the one hand and, on the other, integrity.
