The blacklisted mathematics instructor Chandler Davis, after serving six months in the Danbury federal penitentiary for refusing to cooperate with the House Un-American Activities Committee (HUAC), warned the universities that ousted him and thousands of other professors that the purges would decimate the country’s intellectual life.
“You must welcome dissent; you must welcome serious, systematic, proselytizing dissent—not only the playful, the fitful, or the eclectic; you must value it enough, not merely to refrain from expelling it yourselves, but to refuse to have it torn from you by outsiders,” he wrote in his 1959 essay “...From an Exile.” “You must welcome dissent not in a whisper when alone, but publicly so potential dissenters can hear you. What potential dissenters see now is that you accept an academic world from which we are excluded for our thoughts. This is a manifest signpost over all your arches, telling them: Think at your peril. You must not let it stand. You must (defying outside power; gritting your teeth as we grit ours) take us back.”
But they did not take Davis back. Davis, whom I met a few days ago in Toronto, could not find a job after his prison sentence and left for Canada. He has spent his career teaching mathematics at the University of Toronto. He was one of the lucky ones. Most of the professors ousted from universities never taught again. Radical and left-wing ideas were effectively stamped out. The purges, most carried out internally and away from public view, announced to everyone inside the universities that dissent was not protected. The confrontation of ideas was killed.
