Regula Falsi

around and about the ambit of
a maze of fellow wanderers
each both barrier and passageway
depending upon the approach
shifting not in time but with it
in flux both now and in memory
all paths centripetal to oneself
a center inferred from circumference
not equidistant nonetheless
proximity no measure of traversal
meandering like a celtic knot
a process of successive approximation
ever nearing but never gaining
bringing one only within tolerance
