أن ما ذكر لا يدل على حدوث جميع الأعراض
An objection is that the preceding argument does not establish the origination of every accident.
Even if changing motion and rest are clear examples, what about other accidents such as length, breadth, depth, form, or the lights attributed to celestial bodies? Critics sometimes treat these as enduring attributes and challenge any generalization from observed motion.
A reply may reason from the bearer and the attributes inhering in it. The reasoning must still identify which accidents were shown to originate directly and which depend on further premises.
