Butler, it goes back further than that. Few Americans today realize that the public school movement began 150 years ago as part of an attack on the Catholic Church.
In the mid-nineteenth century, Protestant “Know-Nothings” railed against the millions of newly-arrived Catholic immigrants — “criminals” who had a lot of kids and were starting their own schools, complete with armies of foreign nuns and papist priests. According to Rousas Rushdoony’s history, Horace Mann, the founder of the public school movement in Massachusetts, believed that “the [public] schools are the means, instruments, vehicles, and true church by which salvation is given to society.” Given that goal, Mann “changed the function of education from ‘mere learning’ or religiously-oriented education to ‘social efficiency, civic virtue, and character” (by the twentieth century, character “ceased to be a concern” in the public schools, Rushdoony notes). Mann also demanded that control of community schools be transferred into state hands.
A decade later and a continent away, another pioneer took up the cause. John Swett was responsible for “framing the basic legislation of the state system” as California’s Superintendent of Public Instruction during the 1860s. Swett made his goals perfectly clear: “Children arrived at the age of maturity belong not to the parents but to the State, to society, and to the country,” he insisted — so children should be educated not according to the beliefs of their parents, but those of the government. The “civil religion” taught in government schools was designed to neutralize the papist heresies taught in the parochial schools. For the Know-Nothings, Catholic families were not only the competition: they were the enemy. Catholics were inferiors that had to be raised to the level of civic virtue expected of everyone else.
