The concept of contingency itself involves assumptions as to causality or the lack of causality in the universe.
Causality is an abstraction from the manifest universe.
It is a product of the mind of man and not inherent in the manifested universe. The assumption as to condition and effect fails to recognize that the condition and effect are from one point of view one event in the Whiteheadian sense. Cause is attributed to the event by abstracting from the event contributing factors giving rise to the so-called effect in the passage of time and the extension of space. The concept of agency and contingency implies factors acting upon nonparticipatory manifestation. However, the rationship between cause and effect is a dual relationship, with what we treat as effect influencing the cause and the cause influencing the effect.
