That we know of. Still, the Greeks couldn’t even handle the number zero, so they were deficient in quite a few ways.
------------------------------
So, the Greeks, co-founders of Western Civilization, were deficient in quite a few ways, were they?
Well at least they managed to create a few trivialities, among them;
* Representative Governance (Pericles, Solon.......)
* History (Herodotus.......)
* Literature ( Comedy, Tragedy, Poetry and the Novel......)
* Competitive Athletics ( the Olympic Games)
* Philosophy and Logic (Deductive and Inductive Reasoning)
Perhaps more importantly, they created:
* Geometry (Euclid, Pythagoras........) w/o which structure is not possible.
* Botany which permitted the development of Agriculture expanding Man's life span.
* Medicine
* Physics which defined the Law of Buoyancy, among many, permitting global navigation.
Now reflect a moment, as they did all this w/o tee-vee, college degrees or politics.
Think how deprived these poor things were. Oh, the ghastly horror....................!!!
