Viewpoint diversity is suddenly on everyone’s lips — yet few agree on what it really means. Is it about political balance? Free speech? Academic inclusion? Or something far more vital — the courage to engage across difference? In Viewpoint Diversity: What It Is, Why We Need It, and How to Get It, leading heterodox thinkers tackle one of the most urgent questions of our time: how to keep open inquiry and constructive disagreement alive amid rising conformity on both left and right. Spanning essays on higher education, politics, culture, and the arts, this bold collection offers both sharp diagnosis and practical solutions for cultivating genuine pluralism. Timely, provocative, and refreshingly constructive, Viewpoint Diversity makes the case for a richer, freer, and more resilient public culture — one that thrives not in spite of disagreement, but because of it.
