On an entirely different topic ...
Given my historical interests, I have long been struck by how inaccurate popular conceptions of the Middle Ages are—summed up in the historically obsolete label of "Dark Ages." My usual example is the myth that medieval food was overspiced to hide the taste of spoiled meat, propagated by people who have never read a medieval recipe, let alone cooked from one, or spent as long as twenty seconds thinking about the consequence for a cook of routinely serving spoiled meat, disguised with expensive spices, to his boss. I also have a pair of accounts of scientific reasoning, one from a Norse saga and one from a 14th century North African.
I have just come across a delightful review
of a recent book
on the medieval foundations of modern science, written by a reviewer who shares my attitude towards popular confident ignorance on the subject.
