the two journeys(1) cannot be made at one(2) and the same instant. This is not even a thing of which it could be said, “It is decreed.” Rather, it has no reality and is no thing at all. It is merely something the mind conceives(3) by conceiving(4) an analogous thing in external reality, so that it may judge(5) it to be impossible in external reality. The mind cannot, however, conceive this [in](6) external reality. It can conceive [the coexistence of](7) color and taste in a single substrate, such as white sweetness [and whiteness](8). The mind then poses this question to itself(9): “Can blackness and whiteness coexist in a [single](10) substrate, as color and taste(11) coexist?” It thereby knows that such coexistence is impossible in external reality. It also knows that it is possible for Zayd to be(12) in the east while Amr is in the west(13), and it poses this question in its mind: “Can Zayd himself be in both places, just as Zayd and Amr were?” It thus knows that this is impossible.
