Nevertheless a philosophical study of unity will follow the following course. Since it is Unity that we seek, since it is the principle of all things, the Good, the First that we consider, those who will wish to reach it must not withdraw from that which is of primary rank to decline to what occupies the last, but they must withdraw their souls from sense-objects, which occupy the last degree in the scale of existence, to those entities that occupy the first rank. Such a man will have to free himself from all evil, since he aspires to rise to the Good. He will rise to the principle that he possesses within himself. From the manifold that he was he will again become one. Only under these conditions will he contemplate the supreme principle, Unity. Thus having become intelligence, having trusted his soul to intelligence, educating and establishing her therein, so that with vigilant attention she may grasp all that intelligence sees, he will, by intelligence, contemplate unity, without the use of any senses, without mingling any of their perceptions with the flashes of intelligence. He will contemplate the purest Principle, through the highest degree of the purest Intelligence. So when a man applies himself to the contemplation of such a principle and represents it to himself as a magnitude, or a figure, or even a form, it is not his intelligence that guides him in this contemplation for intelligence is not destined to see such things; it is sensation, or opinion, the associate of sensation, which is active in him. Intelligence is only capable of informing us about things within its sphere. UNITY AS THE UNIFORM IN ITSELF AND FORMLESS SUPERFORM. Intelligence can see both the things that are above it, those which belong to it, and the things that proceed from it. The things that belong to intelligence are pure; but they are still less pure and less simple than the things that are above Intelligence, or rather than what is above it; this is not Intelligence, and is superior to Intelligence. Intelligence indeed is essence, while the principle above it is not essence, but is superior to all beings. Nor is it essence, for essence has a special form, that of essence, and the One is shapeless even intelligible. As Unity is the nature that begets all things, Unity cannot be any of them. It is therefore neither any particular thing, nor quantity, nor quality, nor intelligence, nor soul, nor what is movable, nor what is stable; it is neither in place nor time; but it is the uniform in itself, or rather it is formless, as it is above all form, above movement and stability. These are my views about essence and what makes it manifold.[192] WHY IT IS NOT STABLE, THOUGH IT DOES NOT MOVE.
