 P1 If intrinsic entity arise from itself it would absurdly follow that cause and effect would be identical and they would exist simultaneously. In which case, the production of an effect would be pointless for it would be already in existence. It is thus unreasonable to assume that something already arisen might arise all over again. ([M] 6.8) If an entity in existence still requires arising then an infinite regress would follow ([M] 6. 9–13).
