Text 21.  …we don't mean by it what is described as J externally, but rather something more general, which is: were it to exist externally it would be true of it that it is J, whether it exists externally or not. For we can say “every triangle is a figure” even if there are no triangles existent externally. The meaning is rather that everything which would be a triangle were it to exist would be—in so far as it existed—a figure. (Râzî Mulakhkhas [2002] 141.6–10)
