Written as a short personal reflection, this article explores the development of political science as an organized professional discipline in the United States. At its inception, political science in the United States was principally concerned with political thought and constitutionalism, and it was taught with the public-spirited purpose of educating for citizenship in a constitutional democracy. Twentieth-century methodological trends at one time threatened to remove political thought and constitutionalism from the curriculum of political science, but recent disciplinary trends suggest that American political thought does have a place in twenty-first-century political science.
