بقاء الأجسام وبقاء الأعراض
Persistence of bodies and persistence of accidents.
Classical theologians did not always treat the continued existence of a body and of an accident as identical questions. Many accepted that bodies persist while disputing whether individual accidents persist or are renewed. These positions affect the structure of the argument from origination.
These are historical metaphysical models, not claims to have established the laws of modern physics. The useful distinction is that “the object remains” and “each of its particular features remains numerically unchanged” are different propositions.
