I don't believe that Karl Popper was as deep a thinker as many on this list
do, but I don't think he was as big a fool as THAT!

None of Aristotle's ideas about physics were even close to being correct
and could have been easily refuted even in his own day, but instead it was
held as the gospel truth for almost 2000 years.

As Bertrand Russell said:

"Aristotle maintained that women have fewer teeth than men; although he was
twice married, it never occurred to him to verify this statement by
examining his wives' mouths."

Physics would have been better off if Aristotle had never been born.

I asked you this before but got no answer, if the physical universe does
not exist how would things be different if it did?

Then I am a Platonist and so is everybody who has half a brain because
clearly the appearance of something is not the same as the thing itself.
The sound of broken glass is not broken glass, the look of broken glass is
not broken glass, the feel of broken glass is not broken glass. What "IS"
broken glass? I don't have a complete answer but It must have stable
properties of some sort or I wouldn't be able to identify it as a "thing".
I don't understand why "physical universe" isn't a good name for that
collection of properties.
