The Six Books of Proclus on the Theology of Plato, Volume 2

For if every cause imparts something to that which proceeds from it, more numerous causes will impart a greater number of gifts, but less numerous causes a less number. Hence, of participants some will consist of a greater number of things, but others, of a less number, of which each participates, some indeed through a progression from a greater number of causes, but others from a less. Those, however, which proceed from a greater number of causes are more compounded, but those from a less number of the same causes, are more simple. Every thing, therefore, which is produced by a greater number of causes, is more compounded, but that which is produced by a less number is more simple. For the more compounded participates of those things of which the more simple participates, but the contrary to this is not true.
