As a Stanford undergraduate studying philosophy in the late 1980s, I naturally was drawn to the give-and-take of debate and the desire to bring about freedom through political means. I started a student newspaper to challenge the prevailing campus orthodoxies; we scored some limited victories, most notably in undoing speech codes instituted by the university. But in a broader sense we did not achieve all that much for all the effort expended. Much of it felt like trench warfare on the Western Front in World War I; there was a lot of carnage, but we did not move the center of the debate. In hindsight, we were preaching mainly to the choir — even if this had the important side benefit of convincing the choir’s members to continue singing for the rest of their lives.
