Many years ago, as a young man, I read a very interesting book about the rise of the Communists to power in China. In the last chapter, the author tried to explain why and how this had happened.
Among the factors he cited were the country's educators.
That struck me as odd, and not very plausible, at the time. But the passing years have made that seem less and less odd, and more and more plausible.
Today, I see our own educators playing a similar role in creating a mindset that undermines American society.
Schools were once thought of as places where a society's knowledge and experience were passed on to the younger generation.
But, about a hundred years ago, Professor John Dewey of Columbia University came up with a very different conception of education - one that has spread through American schools of education, and even influenced education in countries overseas.
John Dewey saw the role of the teacher, not as a transmitter of a society's culture to the young, but as an agent of change - someone strategically placed, with an opportunity to condition students to want a different kind of society.
A century later, we are seeing schools across America indoctrinating students to believe in all sorts of politically correct notions. The history that is taught in too many of our schools is a history that emphasizes everything that has gone bad, or can be made to look bad, in America - and that gives little, if any, attention to the great achievements of this country.
If you think that is an exaggeration, get a copy of "A People's History of the United States" by Howard Zinn and read it.
As someone who used to read translations of official Communist newspapers in the days of the Soviet Union, I know that those papers' attempts to degrade the United States did not sink quite as low as Howard Zinn's book.
