As soon as man developed the capability to contemplate who he was in relation to the world about him, he began to wonder if there was a singleness about all objects in his environment. Certainly the differences were visually vast, but could there be a common indivisible building block for all things animate and inanimate?
For instance: if you were able to cut a gold bar in half, and then cut the half piece in half, and then cut the quarter piece in half, and then the eighth, and then the sixteenth, etcetera, when do you have to stop? Is there a point when you would end up with a fragment that could no longer be broken down into a smaller piece (the smallest possible piece still identifiable as gold)? The Greeks named this infinitesimally tiny end piece atomos (atom) or ‘unbreakable’ in Greek.
