no Democritus?
my vote is for him.
He was thought of as crazy as he came up with the theory that everything can be broken down into tiny pieces and would eventually not be able to be broken down anymore.
By the way he was from 460-370 BC and he called these tiny particles that could not be seen or broken down atoms.
Yeah the same atoms that were not discovered until late 1800's when scientists finally found evidence of their existence.
He had a theory that could not be proven for over 2200 years when they concluded he was correct.
There's more (and less) to it than that. He wasn't really proposing a super advanced scientific theory for which there was no evidence at the time (although it turned out that way in retrospect). He was attempting to balance the two great opposing schools of Western philosophy: empiricism (what you see is what there is) and rationalism (only the pure reasoning of the mind is true).
The problem is, in a nutshell, that empiricists have a hard time creating universal rules or even talking about constants (if you can't step in the same river twice can we even call it the same river?). Rationalists, well, if you can't learn from observing, with what are you left?
Democritus compromised. There ARE things that are constant, indivisible, and unchanging - atoms - to appease our innate need for rationalism. They just rearrange themselves all the time to create our ever-changing material world to explain why we need empiricism. So I don't really give him scientific credit, per se (it's not like he was doing electron scattering and needed a theory to support the evidence)... But, even more significantly, I give him credit for coming up with the entire theoretical framework scientists and most people think about the material world: that on some level, we can come down to constants or rules that, through permutation, create the endless variety of our universe. Profound.
Speaking of which, many Greeks considered him their VERY BEST philosopher. The only writings that survive were the tiny bit on atoms, which is really clever and influential stuff. WHAT DID WE LOSE?!
