5. On Potentiality and Actuality.
6. On Quality and Form.
7. On Coalescence.
8. Why Distant Objects appear Small.
9. Against those Declaring the Creator of the World, and the World itself, to be Evil.
The Third Ennead, still keeping to the World, discusses the philosophical implications of some of its features:—
1. On Fate.
2. The First Treatise on Providence.
3. The Second Treatise on Providence.
4. On Our Tutelary Spirit.
5. On Love.
6. On the Impassibility of the Bodiless.
7. On Eternity and Time.
8. On Nature, Contemplation and The One.
9. Various Questions.
25.
These first three Enneads constitute in my arrangement one self- contained section.
The treatise on Our Tutelary Spirit is placed in the Third Ennead because this Spirit is not discussed as it is in itself, and the essay by its main content falls into the class dealing with the origin of man. Similar reasons determined the inclusion in this set of the treatise on Love. That on Time and Eternity is placed in this Third Ennead in virtue of its treatment of Time: that On Nature, Contemplation and The One, because of the discussion of Nature contained in it.
Next to the two dealing with the world comes the Fourth Ennead containing the treatises dealing with the Soul:—
1. On the Essence of the Soul (I.).
2. On the Essence of the Soul (II.).
3. Questions referring to the Soul (I.).
