John Dewey was what we would call today a humanist activist. He was one of the original thirty-four signers of the Humanist Manifesto in 1933 and an honorary member of the Humanist Press Association, which was the predecessor to the American Humanist Association. With a wide range of works that were not only highly respected in academia but also influential in shaping American public policy and dialogue, Dewey is arguably the single most important public intellectual in the history of modern American humanism.
