The function of the rational soul is to think, but she does not limit herself to thinking. Otherwise there would be no difference between her and intelligence. Besides her intellectual characteristics, the soul's characteristic nature, by virtue of which she does not remain mere intelligence, has a further individual function, such as is possessed by every other being. By raising her glance to what is superior to her, she thinks; by bringing them down to herself, she preserves herself; by lowering them to what is inferior to her, she adorns it, administers it, and governs it. All these things were not to remain immovable in the intelligible world, to permit of a successive issue of varied beings, which no doubt are less perfect than that which preceded them, but which, nevertheless, exist necessarily during the persistence of the Principle from which they proceed.
INCARNATE SOULS WEAKEN BECAUSE THEY CONTEMPLATE THE INDIVIDUAL.
4. There are individual souls which, in their conversion[169] towards the principle from which they proceed, aspire to the intelligible world, and which also exercise their power on inferior things, just as light, which does not disdain to throw its rays down to us though remaining suspended to the sun on high. These souls must remain sheltered from all suffering so long as in the intelligible world they remain together with the universal Soul. They must besides, in heaven, share with it the administration of the world; like kings who, being colleagues of the great King of the universe, share the government with Him, without themselves descending from their thrones, without ceasing to occupy a place as elevated as He. But when they pass from this state in which they live with the universal Soul to a particular and independent existence, when they seem weary of dwelling with another, then each of them returns to what belongs to her individually. Now when a soul has done that for a long while, when she withdraws from the universal Soul, and distinguishes herself therefrom, when she ceases to keep her glances directed towards the intelligible world; then, isolating herself in her individual existence, she weakens, and finds herself overwhelmed with a crowd of cares, because she directs her glance at something individual. Having therefore separated herself from the universal Soul as well as from the other souls that remain united thereto, and having attached herself to an individual body, and concentrating herself exclusively on this object, which is subjected to the destructive action of all other beings, she ceases to govern the whole to administer more carefully a part, the care of which forces her to busy herself, and mingle with external things, to be not only present in the body, but also to interpenetrate it.
THIS PROCESS EXPLAINS THE CLASSIC EXPRESSIONS ABOUT HER CONDITION.
Thus, in the common expression, she has lost her wings, and is chained by the bonds of the body, because she gave up the calm existence she enjoyed when with the universal Soul she shared the administration of the world; for when she was above she spent a much happier life. The fallen soul is therefore chained or imprisoned, obliged to have recourse to the senses because she cannot first make use of intelligence. She is, as it is said, buried in a tomb, or cavern. But by her conversion towards thought, she breaks her bonds, she returns upwards towards higher regions, when, starting from the indications of reminiscence she rises to the contemplation of the essences;[170] for even after her fall she always preserves something superior to the body.
SOULS AS AMPHIBIANS.
Souls therefore are necessarily amphibians;[171] since they alternately live in the intelligible world, and in the sense-world; staying longer in the intelligible world when they can remain united to supreme Intelligence more permanently, or staying longer or preponderatingly here below when nature or destiny imposes on them a contrary fate. That is the secret meaning of Plato's words[172] to the effect that the divinity divides the seeds of the souls formed by a second mixture in the cup, and that He separates them into (two) parts. He also adds that they must necessarily fall into generation after having been divided into a definite number. Plato's statement that the divinity sowed the souls,[173] as well as the divinity's address to the other deities, must be taken figuratively. For, in reference to the things contained in the universe, this implies that they are begotten or produced; for successive enumeration and description implies an eternal begetting, and that those objects exist eternally in their present state.
SOULS DESCENDING TO HELP ARE SENT BY GOD.
5. Without any inherent contradiction it may therefore be asserted either,[174] that the souls are sowed into generation, that they descend here below for the perfection of the universe, or that they are shut up in a cavern as the result of a divine punishment, that their fall is simultaneously an effect of their will and of necessity—as necessity does not exclude voluntariness—and that they are in evil so long as they are incarnate in bodies. Again, as Empedocles says, they may have withdrawn from the divinity, and have lost their way, and have committed some fault that they are expiating; or, as says Heraclitus, that rest consists in flight (from heaven, and descent here below), and that the descent of souls is neither entirely voluntary, nor involuntary. Indeed, no being ever falls voluntarily; but as it is by his own motion that he descends to lower things, and reaches a less happy condition, it may be said that he bears the punishment of his conduct. Besides, as it is by an eternal law of nature that this being acts and suffers in that manner, we may, without contradiction or violence to the truth, assert that the being who descends from his rank to assist some lower thing is sent by the divinity.[175] In spite of any number of intermediate parts (which separate) a principle from its lower part, the latter may still be ascribed to the former.[176]
