TFF, now you are talking what I call "pneumatologically"--that is, from the human Spirit (pneuma) from the heart of truth.
You mentioned "stupidity". The difference between stupidity and ignorance is: the latter is curable. laugh

BTW, it would be interesting to know how many great scientific minds of the past were not actually formally educated in science.
Copernicus was a monk.

William Herschel, the great astronomer, was a musician
Discovery of Uranus
Herschel's music led him to an interest in mathematics, and hence to astronomy. This interest grew stronger after 1773, and he built some telescopes and made the acquaintance of Nevil Maskelyne. He observed the Moon, measuring the heights of lunar mountains, and also worked on a catalog of double stars.

Charles Darwin's education? He had a BA in theology from Cambridge.
In 1827, his father, unhappy at his younger son's lack of progress, shrewdly enrolled him in a Bachelor of Arts course at Christ's College, Cambridge to qualify as a clergyman, expecting him to get a good income as an Anglican parson.[15] However, Darwin preferred riding and shooting to studying.[16] Along with his cousin William Darwin Fox, he became engrossed in the craze at the time for the competitive collecting of beetles...

Thomas Edison had little formal education
In school, the young Edison's mind often wandered, and his teacher the Reverend Engle was overheard calling him "addled." This ended Edison's three months of official schooling. He recalled later, "My mother was the making of me. She was so true, so sure of me; and I felt I had something to live for, someone I must not disappoint." His mother then home schooled him.[2] Much of his education came from reading R.G. Parker's School of Natural Philosophy.

And so it goes.
