Key concepts of Aristotelian physics include the structuring of the cosmos into concentric spheres, with the Earth at the centre and celestial spheres around it.
The terrestrial sphere was made of four elements, namely earth, air, fire, and water, subject to change and decay. The celestial spheres were made of a fifth element, an unchangeable aether.
Objects made of these elements have natural motions: those of earth and water tend to fall; those of air and fire, to rise.
The speed of such motion depends on their weights and the density of the medium. Aristotle argued that a vacuum could not exist as speeds would become infinite.
He thought Earth was the center of the universe and that the Sun, Moon, planets, and all the fixed stars revolved around it.
So, this is what Aristotle believed in the period around 350 BCE.
Before that, people simply existed for no reason at all. Except for Thales of Milletus, Socrates and a few others.
But, had they not questioned the workings of nature and Universe, world wouldn’t have known the secrets they revealed and the laws and theories they introduced.
Also, had Galileo not questioned Aristotle’s view, we wouldn’t have been able to understand the actual workings of the Universe as we know them to be today.
Science is all about finding the hidden secrets.
Had all of them just sat back in their chairs stating, “Some things are beyond our understanding and should just be left to God”, we would still be busting ghosts and hailing miracles.
As I think about it, some of us still do.
I don’t really understand the stupidity of ordinary humans.
Maybe, someday when all the imbeciles are ready to accept the ways of science and its importance, I’ll stop and consider the existence of god too.
Until then, “May the force be with you”!
