What does the systemic premise of "interdependence" claim?

That everything is connected to everything else — no element, and no observer, stands fully apart from the web.

Interdependence (Interdependenz) is the assumption that the parts of a living system don't just sit side by side; they continuously affect one another, and pulling on one strand tugs the rest. Practical consequences:

• You cannot understand a part in isolation — its behaviour depends on the others and on its environment and context.
• Side effects are normal, not anomalies: intervene anywhere and the change propagates through the connections.
• It extends to you: the observer is inside the web, not a detached spectator looking in from outside.

This is why systems thinking parallels both modern physics (the world as "one and whole, not separable") and older Eastern traditions (Buddhism, the Vedas: "all is one, all is part of the same whole"). The shared claim is connectedness as the basic fact.

Tip: "Pull one thread and the whole web moves" — that intuition is interdependence.
