The overall campus figures include professional schools and science, technology, business and mathematics departments. In most humanities and social-science departments—especially those central to a liberal education, such as history, English and political science—the share of left-of-center faculty already approaches 100%.
The imbalance is not only a question of numbers. Well-balanced opposing views act as a corrective for each other: The weaker arguments of one side are pounced on and picked off by the other. Both remain consequently healthier and more intellectually viable. But intellectual dominance promotes stupidity. As one side becomes numerically stronger, its discipline weakens. The greater the imbalance between the two sides, the more incoherent and irrational the majority will become.
What we are now seeing on the campuses illustrates this general principle perfectly. The nearly complete exclusion of one side has led to complete irrationality on the other. With almost no intellectual opponents remaining, campus radicals have lost the ability to engage with arguments and resort instead to the lazy alternative of name-calling: Opponents are all “fascists,” “racists” or “white supremacists.”
In a state of balance between the two sides, leadership flows naturally to those better able to make the case for their side against the other. That takes knowledge and skill. But when one side has the field to itself, leadership flows instead to those who make the most uncompromising and therefore intellectually least defensible case, one that rouses followers to enthusiasm but can’t stand up to scrutiny. Extremism and demagoguery win out. Physical violence is the endpoint of this intellectual decay—the stage at which academic thought and indeed higher education have ceased to exist.
