Likewise, if it is said, “This aggregate amounts to one-tenth of an ūqiyya, a nashsh (1), or an istār (2),” it does not follow that every constituent part (3) amounts to one-tenth of an ūqiyya, a nashsh, or an istār (4). For the aggregate arose through the parts being joined to one another, whereas this state of aggregation is not present (5) in the individual parts.
This differs from the case in which it is said (6), “Every constituent part is either nonexistent, existent, possible, necessary, or impossible.” The aggregate must likewise be either nonexistent, existent, possible, necessary, or impossible.
Likewise, if you say, “Every one of the Zanj is black,” it must be either nonexistent, existent, possible, necessary, or impossible.
Likewise, if you say, “Every one of the Zanj is black,” the aggregate must be black. For joining an existent to another existent does not cause it to cease being existent; joining a nonexistent to another nonexistent does not take it out of nonexistence (7); and joining that which is possible in itself or impossible in itself to another of its kind does not cause it to cease being possible in itself or impossible in itself, respectively.
This is unlike that which is impossible in itself (8) only when taken in isolation, but which, through conjunction, becomes—
