It's a pleasure to be with you tonight. I want to say by way of introduction that I'm here because of Tony Marx. Not that he twisted my arm. I mean it in the broadest sense. I can testify that Tony didn’t start provoking 20-year-olds when he became president of Amherst; he provoked and and inspired 20-year-olds when HE was 20 years old. I've been grateful for that bond of friendship since we were roommates one summer in Cambridge nearly 30 years ago.
