Came across this in The University Encyclopedia (of 1902). Showing humans have not changed so much:
... The sad part of the whole matter is that mankind never seems to learn by experience; no new methods of deception are introduced, no real originality or inventive enterprise is ever shown by quacks; they rely on exactly the same old artifices as their predecessors did, and generation after generation are duped by them just as surely."
Since 1902, while politicians and priests have changed little, there has been a series of innovations in medical quackery. When radioactivity was first discovered it was promoted as healthy, and people were burned or even killed by excessive doses. Even before 1902 electromagnetism was promoted as a cure-all; at least it was usually less harmful than radioactivity. Now we give people blood tests and set the parameters narrowly so there are always plenty of people with results outside the parameters, in need of prescription drugs.
The U.S. still has the same two lying, thieving major parties it had in 1902, the Democrats and the Republicans. The more things change, the more they stay the same.
