وبعضها بالدليل وهو طريان العدم
For other accidents, origination is argued from the occurrence of nonexistence or cessation.
When the first occurrence of a quality is not directly seen, its disappearance or possible loss becomes a basis for inference. The argument rests on a contrast between what is eternal and what is subject to nonexistence.
Yet “this particular property has ceased” and “every possible property necessarily ceases” are distinct claims. The former may be grounded in a case; the latter requires a general argument.
