OUTLINE OF NATURES IN THE UNIVERSE.
Other principles remain unmoved while producing and exhibiting their ("hypostases," substantial acts, or) forms of existence. The (universal) Soul, however, is in motion while producing and exhibiting her ("substantial act," or) forms of existence, namely, the functions of sensation and growth, reaching down as far as (the sphere of the) plants. In us also does the Soul function, but she does not dominate us, constituting only a part of our nature. She does, however, dominate in plants, having as it were remained alone there. Beyond that sphere, however, nature begets nothing; for beyond it exists no life, begotten (matter) being lifeless. All that was begotten prior to this was shapeless, and achieved form only by trending towards its begetting principle, as to its source of life. Consequently, that which is begotten cannot be a form of the Soul, being lifeless, but must be absolute in determination. The things anterior (to matter, namely, the sense-power and nature), are doubtless indeterminate, but only so within their form; the are not absolutely indeterminate; they are indeterminate only in respect of their perfection. On the contrary, that which exists at present, namely, (matter), is absolutely indeterminate. When it achieves perfection, it becomes body, on receiving the form suited to its power. This (form) is the receptacle of the principle which has begotten it, and which nourishes it. It is the only trace of the higher things in the body, which occupies the last rank amidst the things below.
