1. Among the questions raised about the soul, we purpose to solve here not only such as may be solved with some degree of assurance, but also such as may be considered matters of doubt, considering our researches rewarded by even only a definition of this doubt. This should prove an interesting study. What indeed better deserves careful examination and close scrutiny than what refers to the soul? Among other advantages, the study of the soul has that of making known to us two order of things, those of which she is the principle, and those from which she herself proceeds. This examination will be in line with the divine precept to "know ourselves."[100] Before seeking to discover and understand the remainder, it is no more than right first to apply ourselves to finding out the nature of the principle that embarks in these researches[101]; and as we are seeking what is lovable, we will do well to contemplate the most beautiful of spectacles (that of our own intellectual nature); for if there be a duality, in the universal (Soul), so much more likely will there be a duality in individual intelligences. We should also examine the sense in which it may be said that souls are sanctuaries of the divinity; but this question will not admit of solution till after we have determined how the soul descends into the body.
ARE INDIVIDUAL SOULS EMANATIONS OF THE UNIVERSAL SOUL?
Now we must consider whether our souls themselves are (emanations) from the universal Soul. It may be insisted that, to demonstrate that our souls are not particles of the universal Soul, it does not suffice to show that our souls go as far (in their procession) as the universal Soul, nor that they resemble (the universal Soul) in their intellectual faculties, granting indeed that such a resemblance be admitted; for we might say that parts conform to the whole they compose. We might invoke Plato's authority, and insist that he teaches this opinion in that (part of the Philebus[102]) where he affirms that the universe is animate: "As our body is a part of the universe, our soul is a part of the Soul of the universe." We might add that (Plato) states and clearly demonstrates that we follow the circular movement of heaven, that from it we receive, our moral habits and condition; that as we were begotten in the universe, our soul must be derived from the surrounding universe[103]; and as each part of us participates in our soul, we ourselves should participate in the Soul of the universe, of which we are parts in the same way as our members are parts of ourselves. Last, we might quote the following words: "The universal Soul takes care of all that is inanimate." This sentence seems to mean that there is no soul outside of the universal Soul; for it is the latter that cares for all that is inanimate.
CONFORMITY TO THE UNIVERSAL SOUL IMPLIES THAT THEY ARE NOT PARTS OF HER.
2. Consider the following answers. To begin with, the assertion that souls conform (to each other), because they attain the same objects, and the reduction of them to a single kind, implicitly denies that they are parts (of the universal Soul). We might better say that the universal Soul is one and identical, and that each soul is universal (that is, that she conforms to the universal Soul, because she possesses all the latter's powers). Now, assertion of the unity of the universal Soul defines her as being something different (from individual souls); namely, a principle which, specially belonging neither to one nor the other, neither to an individual, nor to a world, nor to anything else, itself carries out what is carried out by the world and every living being. It is right enough to say that the universal Soul does not belong to any individual being, inasmuch as she is (pure) being; it is right enough that there should be a Soul which is not owned by any being, and that only individual souls should belong to individual beings.
LIMITATIONS TO THE USE OF THE TERM "PARTS," IN PHYSICAL THINGS.
But we shall have to explain more clearly the sense in which the word "parts" must here be taken. To begin with, there is here no question of parts of a body, whether homogeneous or heterogeneous. We shall make but a single observation, namely, that when treating of homogeneous bodies, parts refer to mass, and not to form. For instance, take whiteness. The whiteness of one part of the milk, is not a part of the whiteness of all the milk in existence; it is the whiteness of a part, and not the part of whiteness; for, taken in general, whiteness has neither size nor quantity. Only with these restrictions can we say that there are parts in the forms suitable to corporeal things.
WHEN APPLIED TO INCORPOREAL THINGS, "PARTS" HAVE DIFFERENT SENSES.
Further, treating of incorporeal things, "parts" is taken in several senses. Speaking of numbers, we may say that two is a part of ten (referring exclusively to abstract numbers). We may also say that a certain extension is a part of a circle or line. Further, a notion is said to be a part of science.
