Plotinos: Complete Works, v. 4 In Chronological Order,...

17. Let us examine if the "reasons" contained in the Soul are thoughts. How could the Soul produce by thoughts? It is the Reason which produces in matter; but the principle that produces naturally is neither a thought nor an intuition, but a power that fashions matter unconsciously, just as a circle gives water a circular figure and impression. Indeed, the natural generative power has the function of production; but it needs the co-operation of the governing (principle) of the Soul, which forms and which causes the activity of the generative soul engaged in matter. If the governing power of the Soul form the generative soul by reasoning, it will be considering either another object, or what it possesses in herself. If the latter be the case, she has no need of reasoning,264 for it is not by reasoning that the Soul fashions matter, but by the power which contains the reasons, the power which alone is effective, and capable of production. The Soul, therefore, produces by the forms. The forms she transmits are by her received from the Intelligence. This Intelligence, however, gives the forms to the universal Soul which is located immediately below her, and the universal Soul transmits them to the inferior soul (the natural generative power), fashioning and illuminating her. The inferior soul then produces, at one time without meeting any obstacles, at others, when doing so, although, in the latter case, she produces things less perfect.

As she has received the power of production, and as she contains the reasons which are not the first (the "seminal reasons," which are inferior to the Ideas) not only does she, by virtue of what she has received, produce, but she also draws from herself something which is evidently inferior (matter).265 It doubtless produces a living being (the universe), but a living being which is less perfect, and which enjoys life much less, because it occupies the last rank, because it is coarse and hard to manage, because the matter which composes it is, as it were, the bitterness or the superior principles, because it spreads its bitterness around her, and communicates some of it to the universe.
