I collect old medical textbooks and I strongly believe our doctors today know less than did doctors at ~1900. Would be amazing to know what information even older medical texts contained.
I agree they probably knew more medical information, but how much of it was correct…
There’s the famous cliche of the medical students first lecture. (Paraphrasing) The professor goes up and says “Fifty percent of what you learn here will be found to be wrong in 20 years. The problem is we don’t know which 50%.
Read about the history of cancer research and its various themes as to the origin of cancer as a great look into just one subset of medicine.
EDIT: Another great way to see the errors of the past is to read wikipedia articles on American presidents and read how they died. Their final diagnoses and treatments are often vague and shocking (respectively) and often people are wondering if they would have survived if they hadn't been attended to by physicians of the time, which were probably the most well-renowned. For example, Zachary Taylor or George Washington.
I see a lot of people romanticizing the turn of the century 20th century. “Money was harder then” or “people had more grip strength”. This is a first time I have heard someone claim (Western) doctors were more advanced.
Tangent, but I never understood the cargo-cult anti-smoking culture in the US; it was a perfect reflection of their media hypnotization. The people that would do a thousand different rebellious, risky, or damaging stuff would recoil in horror if you ask if they ever had a cigarette, as if one puff will char and shrivel your lungs or something.
You're 100% right and I see this kind of attitude all the time and it drives me crazy. Especially when people are worried about what others are doing, or complaining about second hand smoke outdoors, etc.
People really need to learn to just live their fucking lives. Or at least shut the fuck up and let other people live theirs.
