"We live in a world of meanings, not words or sounds. We live in a world of arcs, not points."

This is fundamental; line signifies the points; or the line is the meaning of the points; as when you fit a line to points of observations.

This fact is built into our perception and into science as well because all observations are points and meaning is the line that passes through all points; and therefore all meaning is interpretation.

The title is unfortunate ("To live forever"?) but the article makes good points.
