It is true that John Dewey as a citizen was a great social reformer. And it is true that he believed that the central and continuing concern of philosophy involved problems of moral choice and policy on which all reflective human beings must act. But this does not entail the view that philosophy is social-reformist or revolutionary or counterrevolutionary. And still less does it justify any demand that philosophers, organized as a professional association to further the interests of philosophic study and the teaching of philosophy, take stands on specific political issues or programs except those that bear on their freedom to pursue their professional activity.
