On the occasion of Constitution Day, Education Secretary Betsy DeVos delivered her first major address on free speech in higher education – and she didn’t hold back.

In her prepared remarks at the National Constitution Center in Philadelphia, DeVos went beyond merely describing the problem to actually diagnosing its cause: ascendant moral relativism. In that regard, her take was sophisticated, and far more interesting than most complaints about the state of speech in education. “The issue is that we have abandoned truth,” the secretary contended, pointing a finger at “the pernicious philosophy of relativism” which, she said, “teaches that there is no objective truth.”
