There is no motion in a straight line. A straight line infinitely projected becomes a circle.
The straight line belongs to Man. The curved line belongs to God
Cancer is not a straight line. It's up and down.
We know there is no progress in a straight line.
Straight lines vary only in length, and therefore are least ornamental.
There is no straight line to a dream.
Draw a straight line and follow it.
God draweth straight lines but we call them crooked.
The straight line is ungodly.
