This series of short miscellaneous notes was inserted by Porphyry to make up the ninth treatise in the third Ennead (set of nines). The ideas contained in them may be found in other treatises, although the discussion of the unity of Intellect (3.9.1), while promoting his usual view, does give some consideration to the idea of an Intellect at rest, a concept entertained by Amelius.
§1. Interpretation of Timaeus 39E7–9. Intellect and its object are a unity.
§2. We are in the intelligible world when we are unified like the theorems of a complete science.
§3. Souls are not in body but rather the opposite. Individual souls, however, do in a certain sense depart from their origin and return, look to what is above or what is below.
§4. Multiplicity comes from the One because the One is everywhere and nowhere.
§5. Intellect is matter for soul.
§6. There is an Intellect at rest prior to our own intellect as thinking.
§7. The One transcends motion, rest, and thinking.
§8. Potentiality and actuality in corporeals and incorporeals.
§9. The One is beyond all activity and thinking.
