8.69

The Commentary states: It is not that these two kinds, traction and generative, belong solely to the entirety of the two causes of traction and generative among the ten causes. Why is this? Within these two there are non-direct causes, so if they subsumed them completely, it would be too broad, because the productive is a direct cause; and within the remaining four causes such as bringing-forth, there are seeds of direct cause, so if they subsumed only the two, without subsuming [the rest], it would be too narrow.
