“Men will of their own accord gradually work their way out of barbarism so long as artificial measures are not deliberately adopted to keep them in it.”

Now a perfect example of this would be of slavery. Slaves were treated like barbarians, and were forced to not work their way out of it. However as history will show, and the world around you as well, once the Emancipation Proclamation was passed, loads of freedmen were roaming around with not much idea of what to do with the new found freedom. However give them some time, and today you have an African American as president.
