cause and effekt

"Nonlinear and statistical causality bring back to the philosophical
conception of the causal link some of the complexity that was taken
away by the notion of constant conjunction. Additional complexity may
come from an analysis of catalysis, an extreme form of non linear
causality in which an external cause produces an event that acts
merely as a trigger for an entire sequence of further events. But
while restoring the richness of causal relations does make them more
likely to explain complex material behavior, it is a restoration of
their objectivity that will have more profound philosophical
consequences: material events producing other material events in ever
more intricate series, whether there are humans around to observe them
or not." - Manuel DeLanda,
