I never inquired about his level of education but a friend of mine that read on a second or third grade level was a close observer of animals including the human animal. His understanding surpassed that of many well educated people, some with degrees in psychology. A simple man, it was a waste of time to try to blow a stream of bullshit past him. He saw right through the person trying.
He was one of the finest examples of the difference between intelligent and educated I have ever seen. One of the great ironies I observed, they spent years teaching someone the theories behind farming, some right, some wrong. Then before they gave the person a doctorate they sent them to the lab farm for a few years where Red taught them how to farm and work livestock. It was funny, when they came to the farm with all of their "book learning" they couldn't function as well as a ten or twelve year old farm boy. Odds are they would have been killed or badly injured before they knew their way around a farm without Red there.
I learned there was intelligent and there was educated. The two aren't always one and the same and I have met many a person educated beyond their intelligence. Damn, I miss my old friend!
