No, I meant that when you learn about e.g. the chemical elements, you don't also learn who discovered each of them. It's accepted knowledge; you're taught it as facts.
In philosophy, most of the exam questions have someone's name in them. E.g. "explain x's concept of y."
I also had problems with the sentence, probably because it doesn't ring especially true. I can name the discoverer of most of what I know about physics, right from the names: Newtonian physics, Bohr's model, the Schrodinger equation, Euclidian geometry, Gaussian curves... E=Mc2...
FWIW, I too got stuck at that sentence like nowhere else in the text; it took me some tries to macro-expand. Maybe your proofreaders got past it without blinking because they are more acquainted with that point?
(Although Newtonian physics and Euclidean geometry are not really counterexamples.)
