The circular path has an outer diameter of around 40 meters. In the middle of the path, 26 sandstone monoliths, 200 cm long and 50 cm high and wide, are arranged in a circle. Each stone bears a part of the endless sentence carved into it: "A observes B, "B observes C"... to "Z observes A".
The passer-by should feel invited to take a walk along the path and sit down on one of the stone blocks, which are the exact height of a seat. From their seat, they can look around, perhaps at the building and the trees and lawns, and also observe the people passing by.
The artist has drawn attention to the fact that his work responds to the work of Bielefeld sociologist Niklas Luhmann. This is also indicated by an upright block of stone, which is placed next to the circle of stones and bears the inscription "Gesellschaftsspiel".
Ludger Gerdes' work straddles the boundary between sculpture and architecture, image and language. It not only visualizes a figure of thought, but also invites you to take a seat and think about what the sculpture expresses. You automatically do what is written on the stones.
