First tractate - Fate. EnneadsIII1

In the action of our Souls all that is done of their own motion in the light of sound reason is the Soul's work, while what is done where they are hindered from their own action is not so much done as suffered. Unwisdom, then, is not due to the Soul, and, in general - if we mean by Fate a compulsion outside ourselves - an act is fated when it is contrary to wisdom. Enneads: III I. 10

But all sums to a unity, a comprehensive Providence. From the inferior grade downwards is Fate: the upper is Providence alone: for in the Intellectual Kosmos all is Reason-Principle or its Priors-Divine Mind and unmingled Soul-and immediately upon these follows Providence which rises from Divine Mind, is the content of the Unmingled Soul, and, through this Soul, is communicated to the Sphere of living things. Enneads: III III. 5
