Few philosophers can boast of having their picture on a U.S. postage stamp. Or on the cover of Time magazine. Or merit a 3,349-word obituary in The New York Times.

Such was the fame and influence of John Dewey, the Columbia philosophy professor of whom Columbia historian Henry Steele Commager wrote in 1950 that “for a generation, no major issue was clarified until Dewey had spoken.” Once considered America’s leading liberal thinker, Dewey’s reputation has dimmed since his 1952 death, but one professor on campus is seeking to change that.
