C.S. Lewis believed in democracy. But not for reasons most Americans would identify. For Lewis, democracy is a political necessity, not a political ideal. And when we treat democracy as a political or, indeed, moral and social ideal, things tend to go sideways; democracy becomes an instrument of tyranny. In this presentation, we will explore what the beloved Oxbridge don and “mere Christian” thought about democracy—its purpose and its perils—and what American evangelicals might glean from his insights.
