If number 1 did not exist, nothing could exist other than fundamental chaos. Mathematics would collapse. Our solid ground never could be, as it would give like quick sand in the absence of 1.
Everything physical is a distinct object made of atoms on different levels. Underneath in the subatomic realm, it is chaotic and exceedingly complex. However, all physical objects arrive to our perception as 1 from the chaos, intact.
For there to be single atoms, molecules, cells, larger physical objects, etc, there must be order in the first place. Any number can be multiplied by 1 and equal the same number. Well, we all take that for granted. Without 1, there is no reference for anything, including every word and letter you are looking at now.
Where did the original 1 come from? The infinite regression of the universe’s origins such as number 1 in particular, necessitates a starting point. Coincidentally, there is a being who calls xemself “I AM,” the origin of existence. Yahweh my God is 1.
Thinking about and experiencing the number 1, knowing God is the ground we stand on, allows me to know myself and others better, and see the world more clearly.
To deny the necessity and origin of 1 is to deny yourself and others of existence, resulting in a Cartesian self – some more so than others.
