The Hoover Institution’s journal, Defining Ideas, offered a ringing endorsement of Greg’s 
book, Unlearning Liberty: Campus Censorship and the End of American Debate, in a recent review:
His lively book is at once a relentless exposure of the intellectual intolerance institutionalized in higher education, and a passionate defense of the value of free thought and expression.
Defining Ideas reviews numerous examples from the book and concludes that universities are often not the “marketplace of ideas” they sometimes publicly claim to be.
