Positions Determined by Directions and Distances
15. Put another dot (B) on your paper, not far from dot “A.”
We have now a relation of two positions,—the relation of position “A” to position “B.” The relation is one of Directions and of Distances. Proceeding from “A” in a certain direction to a certain distance we reach “B.” Proceeding from “B” in a certain direction and to a certain distance we reach “A.” Every position means two things; a direction and a distance taken from some point which may be described as the premise-point.
