I've written a lot on that problem. It's safe to say that there are advantages and disadvantages of a modern education. I'm reminded of Leo Tolstoy's advocacy of the simple life. But we shouldn't shoot the messenger: education confronts us with the objective facts of our state in nature, facts that are often discouraging. With no gods, we have indeed only ourselves, our societies, and our fictions in the wide universe to comfort us. Sometimes these fail, so we struggle with alienation just by being relatively "enlightened." As I say, I've written a lot on that.
