Geometric Philosophy.

The actually title of this post is:
"Geometric Philosophy (and the theological implications therein; as if there can't be theological implications)"
I didn't have a very good geometry teacher in high school. In fact, my best friend and I sometimes actually taught the class. Geometry and philosophy are things that have always just "clicked" for me.
There is a somewhat commonly used phrase cited as, "It (meaning something) comes full circle." Can something really "come full circle?" What does that even mean? If a circle is not a full circle then it is not even a circle at all. A not full circle would be an arc (not to be confused with anything involving Joan, the Covenant, or Noah). The entire concept of a circle, however, may only be accepted if one presumes that an infinite number of points between two other points can proceed infinitely to connect with yet another point.
Confused? Try to understand God.
