Kandinsky; POINT AND LINE TO PLANE (1926)

A line is a track following "the destruction of the intense self-contained repose of the point.

"When a force coming from without moves the point in any direction, the first type of line results; the initial direction remains unchanged, and the line has the tendency to run in a straight course to infinity."


the simple curved line is really "a straight line which has been brought out of its course by constant sideward pressure — the greater was this pressure, the farther went the diversion from the straight line"
