Rushdoony, a staunch advocate of homeschooling, viewed it as a way to combat the intentionally secular nature of the U.S. public school system. He vigorously attacked progressive school reformers such as Horace Mann and John Dewey and argued for the dismantling of the state's influence in education in three works: "Intellectual Schizophrenia" (a general and concise study of education), "The Messianic Character of American Education" (a history and castigation of public education in the U.S.), and "The Philosophy of the Christian Curriculum" (a parent-oriented pedagogical statement), each of which are still promoted by the Chalcedon Foundation.
