Education in America, and particularly higher education, has become increasingly hostile to the free exchange of ideas. On many campuses, a climate of intellectual conformity has replaced open debate and inquiry, stifling discussion on a host of topics ranging from history to science to economics. Dissenters are demonized, ostracized or otherwise treated with scorn and derision. This disrupts the process of discovery and challenge that is at the root of human progress. Holland embraced this philosophy—best expressed by the phrase “Listen even to the other side”—in the 17th century, contributing to it becoming the most prosperous country in the world at the time.
