Plotinus: 5th Aennead, 1st Tractate
Translated by Stephen Mackenna and B. S. Page
Grasp the upward neighbour of the soul, its prior and source.
Soul, for all the worth we have shown to belong to it, is yet a secondary, an image of the Intellectual-Principle: reason uttered is an image of the reason stored within the soul, and in the same way soul is an utterance of the Intellectual-Principle: it is even the total of its activity, the entire stream of life sent forth by that Principle to the production of further being; it is the forthgoing heat of a fire which has also heat essentially inherent. But within the Supreme we must see energy not as an overflow but in the double aspect of integral inherence with the establishment of a new being. Sprung, in other words, from the Intellectual-Principle, Soul is intellective, but with an intellection operation by the method of reasonings: for its perfecting it must look to that Divine Mind, which may be thought of as a father watching over the development of his child born imperfect in comparison with himself.
Thus its substantial existence comes from the Intellectual-Principle; and the Reason within it becomes Act in virtue of its contemplation of that prior; for its thought and act are its own intimate possession when it looks to the Supreme Intelligence; those only are soul-acts which are of this intellective nature and are determined by its own character; all that is less noble is foreign [traceable to Matter] and is accidental to the soul in the course of its peculiar task.
In two ways, then, the Intellectual-Principle enhances the divine quality of the soul, as father and as immanent presence; nothing separates them but the fact that they are not one and the same, that there is succession, that over against a recipient there stands the ideal-form received; but this recipient, Matter to the Supreme Intelligence, is also noble as being at once informed by divine intellect and uncompounded.
What the Intellectual-Principle must be is carried in the single word that Soul, itself so great, is still inferior.
But there is yet another way to this knowledge:
Admiring the world of sense as we look out upon its vastness and beauty and the order of its eternal march, thinking of the gods within it, seen and hidden, and the celestial spirits and all the life of animal and plant, let us mount to its archetype, to the yet more authentic sphere: there we are to contemplate all things as members of the Intellectual- eternal in their own right, vested with a self-springing consciousness and life- and, presiding over all these, the unsoiled Intelligence and the unapproachable wisdom.
