Were medieval people simpletons?
I'm using 1120AD as my starting point.
Formal education=none, for the most part
Even if they were formally educated what quality was the school? I don't think Oxford or Cambridge were founded yet, but if they were teaching people about the four humors that determined health was hardly useful. The double entry accounting system hadn't appeared yet either so I wonder what use an economics degree would have been.
I know the answer from some of you will be, look around, they had commerce and building and a closely knitted society.
My response is even a blind squirrel finds the occasional nut. And I believe most of their elaborate building was done empirically. Build a monster cathedral and hope it stands up.
I have this image that most people of that era were savages or morons. The savages would be the Lords and Barons and the morons were everyone cowtowing to these insipid savages.
I bet the average person in this medieval time frame spent most of their day doing mindless field work for their Lord only to come home to a boiled cabbage or two. They had few external sources of information to broaden their minds, no libraries, internets, TV , newspapers.
Ergo, they must have been easily led and persuaded simpletons.
