The Port Huron Statement was one of the most important manifestos of the New Left in the United States. A foundational statement of the theme of “participatory democracy,” the text had an important influence on post-1960s politics and, arguably, on post-1960s political science. The recent publication of a new edition of the Statement is an occasion for reflection on its importance. And so we have invited a distinguished cast of political scientists shaped by the events of the sixties to comment on the impact of the Statement on their own way of envisioning and practicing political science.
