I had lunch with Howard Zinn just a few weeks ago, and I’ve seldom had more fun while talking about so many matters that were unreservedly unpleasant: the sorry state of government and politics in the U.S., the tragic futility of our escalation in Afghanistan, the plight of working people in an economy rigged to benefit the rich and powerful.

Mr. Zinn could talk about all of that and more without losing his sense of humor. He was a historian with a big, engaging smile that seemed ever-present. His death this week at the age of 87 was a loss that should have drawn much more attention from a press corps that spends an inordinate amount of its time obsessing idiotically over the likes of Tiger Woods and John Edwards.

Mr. Zinn was chagrined by the present state of affairs, but undaunted. “If there is going to be change, real change,” he said, “it will have to work its way from the bottom up, from the people themselves. That’s how change happens.”

We were in a restaurant at the Warwick Hotel in Manhattan. Also there was Anthony Arnove, who had worked closely with Mr. Zinn in recent years and had collaborated on his last major project, “The People Speak.” It’s a film in which well-known performers bring to life the inspirational words of everyday citizens whose struggles led to some of the most profound changes in the nation’s history. Think of those who joined in  and in many cases became leaders of  the abolitionist movement, the labor movement, the civil rights movement, the feminist revolution, the gay rights movement, and so on.
