R. J. Rushdoony, Intellectual Schizophrenia: Culture, Crisis, and Education, 1961. Outstanding analysis of why we need to be consistent in educating our children, not sending them off to public schools and then to church where they hear opposite things. Don’t miss this one!
Christian scholar Samuel Blumenfeld wrote the excellent work Is Public Education Necessary?, and in it he traces the origin of public education back to New England liberals who wanted to evangelize the nation for liberalism (beginning in the early 1800s and gaining force the rest of the century). This is one of the most incredible books I’ve ever read, and the historical research is superb. Get this book! Try http://www.abebooks.com.
