Nature and knowledge cannot be understood in isolation. Every phenomenon emerges from a network of interactions.
„In der großen Verkettung der Ursachen und Wirkungen darf kein Stoff und keine Tätigkeit isoliert betrachtet werden.“
(In English: “In the great chain of causes and effects, no substance and no activity may be considered in isolation.”)
— Alexander von Humboldt, Ideen zu einer Geographie der Pflanzen (1807)
