Hence it is the most similar of all things to _the one_, and unites the comprehension of beings in itself to the first principle of the whole of things, through which all beings, and non-being, wholes and parts, forms and the privations of forms subsist, which privations do not necessarily participate of being, but it is entirely necessary that they should participate of _the one_. These things as it appears to me persuaded the Elean guest in the Sophista, when discussing that which is perfectly being, to admit that not only being is there, but also life, intellect and soul. For if true and real being is venerable and honorable, intellect is there in the first place, says he. For it is not lawful for that which is of itself venerable and immaterial to be without intellect. But if intellect is in that which is perfectly being, intellect will entirely be moved. For it is not possible for intellect ever to subsist, either without motion or permanency. But if intellect is moved and stands still, there are in being both life and motion. Hence, from what has been said, three things become apparent, viz. being, life and intellect. Moreover, soul also in the next place is discovered through these things. For it is necessary, says he, that life and intellect which before were by themselves, should also be in soul. For every soul is a plenitude of life and intellect, participating of both, which the Elean guest indicating adds, “Shall we say that both these are inherent in it, but yet it does not possess these in soul?” For to _possess_, as some one says in a certain place, is secondary to _existing_. And soul indeed participates of each of these according to the peculiarity of itself; but it mingles the rational form of its own hyparxis, with the intellectual vivific power. But both intellect and life subsist prior to soul, the former as being moved and standing still at one and the same time, and the latter as being motion and permanency. These four monads also, soul, intellect, life and being are not only mentioned by Plato here, but in many other places. And as in soul all things subsist according to participation, so in intellect the things which are prior to it subsist, and in life that which is prior to life. For we say that life exists, or has a being. Or how could it be said to be arranged in being unless it participated of being? We likewise say that intellect is and lives. For it is moved, and is a portion of being. Hence it is the third of the more comprehensive monads. Prior however to beings which are participated, it is every where necessary that imparticipable causes should subsist, as was before demonstrated, conformably to the similitude of beings to _the one_. Being therefore which is primarily being, is imparticipable; but life first participates of being, yet is imparticipable, being exempt from intellect. And intellect is filled indeed from being and life; but is imparticipable in souls, and in the natures posterior to itself.
