 Horace Mann and John Dewey were actually pretty open about what they wanted to do. John Dewey's writings, that he wanted to use the government education system to completely restructure everything we know and love. The guy was one of the signers and one of the drafters of the first humanist manifesto, so he was openly anti-Christian. If you go and read the humanist manifesto, they wanted the true religion out of the school system, and they wanted to put their false religion into the school system.
