والأول ما تطابق فيه آراء قوم.
The first class consists of propositions on which the opinions of a community coincide.
The word qawm matters: agreement can belong to a particular population, era, locality, or learned discipline. It need not be universal.
A useful question follows: does agreement result from a substantive proof, or from habit, upbringing, and shared inclinations? Such a distinction matters when assessing the premise beyond its dialectical role.
