ADDRESSING..................4
Such as imagine that beings are governed by luck or chance, and that they depend on material causes are far removed from the divinity, and from the conception of unity. It is not such men that we are addressing, but such as admit the existence of a nature different from the corporeal one, and who at least rise (to an acknowledgment of the existence of) the Soul. These should apply themselves to the study of the nature of the soul, learning, among other truths, that she proceeds from Intelligence, and that she can achieve virtue by participating in Intelligence through reason. They must then acknowledge the existence of an Intelligence superior to the intelligence that reasons, namely, to discursive reason. They must (also realize) that reasonings imply an interval (between notions), and a movement (by which the soul bridges this interval). They must be brought to see that scientific knowledge consists also of reasons of the same nature (namely, rational notions), reasons suitable to the soul, but which have become clear, because the soul has received the succession of intelligence which is the source of scientific knowledge. By intelligence (which belongs to her), the soul sees the divine Intellect, which to it seems sensual, in this sense that it is perceptible by intelligence, which dominates the soul, and is her father; that is, the intelligible world, a calm intellect which vibrates without issuing from its tranquility, which contains everything, and which is all. It is both definite and indefinite manifoldness, for the ideas it contains are not distinct like the reasons (the rational notions), which are conceived one by one. Nevertheless, they do not become confused. Each of them becomes distinct from the others, just as in a science all the notions, though forming an indivisible whole, yet each has its own separate individual existence. This multitude of ideas taken together constitutes the intelligible world. This is the (entity) nearest to the First. Its existence is inevitably demonstrated by reason, as much as the necessity of the existence of the Soul herself; but though the intelligible world is something superior to the Soul, it is nevertheless not yet the First, because it is neither one, nor simple, while the one, the principle of all beings, is perfectly simple.	Tratado 9, 5
On examining many other assertions (of the Gnostics), or rather, all of their assertions, we find more than enough to come to some conclusion concerning the details of their doctrines. We cannot, indeed, help blushing when we see some of our friends, who had imbued themselves with (Gnostic) doctrines before becoming friends of ours, somehow or another persevere therein, working zealously to try to prove that they deserved full confidence, or speaking as if they were still convinced that they were based on good grounds. We are here addressing our friends, not the partisans (of the Gnostics). Vainly indeed would we try to persuade the latter not to let themselves be deceived by men who furnish no proofs — what proofs indeed could they furnish? — but who only impose on others by their boastfulness.	Tratado 33, 10
Another error of the (Gnostics) is their teaching that intelligible beings are not beyond the reach of being affected by human beings. When the (Gnostics) utter magic incantations, addressing them to (intelligible beings), not only to the Soul, but to the Principles superior thereto, what are they really trying to do? To bewitch them? To charm them? Or, to influence them? They therefore believe that divine beings listen to us, and that they obey him who skilfully pronounces these songs, cries, aspirations and whistlings, to all of which they ascribe magic power. If they do not really mean this, if they by sounds only claim to express things which do not fall under the senses, then, through their effort to make their art more worthy of respect, they unconsciously rob it of all claim to respect, in our estimation.	Tratado 33, 14
The revolution of the universal Sphere leads us therefore to the recognition of time, within which it occurs. Not only is time that in which (all things “become,” that is, grow), but time has to be what it is even before all things, being that within which everything moves, or rests with order and uniformity. This is discovered and manifested to our intelligence, but not produced by regular movement and rest, especially by movement. Better than rest, indeed, does movement lead us to a conception of time, and it is either to appreciate the duration of movement than that of rest. That is what led philosophers to define time as the measure “of” movement, instead of saying, what probably lay within their intention, that time is measured “by” movement. Above all, we must not consider that definition as adequate, adding to it that which the measured entity is in itself, not limiting ourselves to express what applies to it only incidentally. Neither did we ever discern that such was their meaning, and we were unable to understand their teachings as they evidently posited the measure in the measured entity. No doubt that which hindered us from understanding them was that they were addressing their teachings to learned (thinkers), or well prepared listeners, and therefore, in their writings, they failed to explain the nature of time considered in itself, whether it be measure or something measured.	Tratado 45, 13
ADDS........................23
Souls therefore are necessarily amphibians; 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 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, 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.	Tratado 6, 4
This is how Plato establishes three degrees in the hierarchy of being: “Everything is around the king of all.” He is here speaking of first rank entities. He adds, “What is of the second order is around the second principle; and what is of the third order is around the third principle.” Plato further says that “God is the father of the cause.” By cause, he means Intelligence; for, in the system of Plato, it is Intelligence which plays the part of demiurgic creator. Plato adds that it is this power that forms the Soul in the cup. As the cause is intelligence, Plato applies the name of father to the absolute Good, the principle superior to Intelligence and superior to “Being.” In several passages he calls the Idea “existence and intelligence.” He therefore really teaches that Intelligence is begotten from the Good, and the Soul from Intelligence. This teaching, indeed, is not new; it has been taught from the most ancient times, but without being brought out in technical terms. We claim to be no more than the interpreters of the earlier philosophers, and to show by the very testimony of Plato that they held the same views as we do.	Tratado 10, 8

The first philosopher who taught this was Parmenides, who identified Existence and Intelligence, and who does not place existence among sense-objects, “for, thought is the same thing as existence.” He adds that existence is immovable, although being thought. Parmenides thus denies all corporeal movement in existence, so as that it might always remain the same. Further, Parmenides compares existence to a sphere, because it contains everything, drawing thought not from without, but from within itself. When Parmenides, in his writings, mentions the One, he means the cause, as if he recognized that this unity (of the intelligible being) implied manifoldness. In the dialogue of Plato he speaks with greater accuracy, and distinguishes three principles: the First, the absolute One; the second, the manifold one; the third, the one and the manifold. He therefore, as we do, reaches three natures.	Tratado 10, 8
Are matter and privation substantially identical, yet logically distinct, in this sense that privation does not signify the presence of anything, but rather its absence? That it is the negation of beings, and is synonymous with nonentity? Negation adds no attribute; it limits itself to the assertion that something is not. In a certain sense, therefore, privation is nonentity.	Tratado 12, 14
Plato says, “The intelligence sees the ideas comprised within the existing animal.” He adds, “The demiurge conceived that this produced animal was to comprise beings similar and equally numerous to those that the intelligence sees in the existing animal.” Does Plato mean that the ideas are anterior to intelligence, and that they already exist when intelligence thinks them? We shall first have to examine whether the animal is identical with intelligence, or is something different. Now that which observes is intelligence; so the Animal himself should then be called, not intelligence, but the intelligible. Shall we therefrom conclude that the things contemplated by intelligence are outside of it? If so, intelligence possesses only images, instead of the realities themselves — that is, if we admit that the realities exist up there; for, according to Plato, the veritable reality is up there within the essence, in which everything exists in itself.	Tratado 13, 1
It is to this (universal) Soul especially that may be applied these words of Plato:317 “The general Soul cares for all that is inanimate.” The other (individual) souls are in different conditions. “The Soul (adds Plato), circulates around the heavens successively assuming divers forms”; that is, the forms of thought, sense or growth. The part which dominates in the soul fulfills its proper individual function; the others remain inactive, and somehow seem exterior to them. In man, it is not the lower powers of the soul that dominate. They do indeed co-exist with the others. Neither is it always the best power (reason), which always dominates; for the inferior powers equally have their place. Consequently, man (besides being a reasonable being) is also a sensitive being, because he possesses sense-organs. In many respects, he is also a vegetative being; for his body feeds and grows just like a plant. All these powers (reason, sensibility, growth), therefore act together in the man; but it is the best of them that characterizes the totality of the man (so that he is called a “reasonable being”). On leaving the body the soul becomes the power she had preponderatingly developed. Let us therefore flee from here below, and let us raise ourselves to the intelligible world, so as not to fall into the pure sense-life, by allowing ourselves to follow sense-images, or into the life of growth, by abandoning ourselves to the pleasures of physical love, and to gormandizing; rather, let us rise to the intelligible world, to the intelligence, to the divinity!	Tratado 15, 2
Two kinds of qualities must be distinguished; the essential quality, which is a peculiarity of its being, and the mere quality, which affects the being’s classification. The mere quality introduces no change in the essence, and causes none of its characteristics to disappear; but, when the being exists already, and is complete, this quality gives it a certain exterior disposition; and, whether in the case of a soul or body, adds something to it. Thus visible whiteness, which is of the very being of white lead, is not of the being of the swan, because a swan may be of some color other than white. Whiteness then completes the being of white lead, just as heat completes the being of fire. If igneousness is said to be the being of fire, whiteness is also the being of white lead. Nevertheless, the igneousness of the visible fire is heat, which constitutes the complement of its being; and whiteness plays the same part with respect to white lead. Therefore (differing according to the difference of various beings) the same things will be complements of being, and will not be qualities, or they will not be complements of being, and will be qualities; but it would not be reasonable to assert that these qualities are different according to whether or not they are complements of being, since their nature is the same.	Tratado 17, 1
What we call a complement of being should not be termed a quality, because they are actualizations of being, actualizations which proceed from the reasons and the essential potentialities. Qualities are therefore something outside of being; something which does not at times seem to be, and at other times does not seem not to be qualities; something which adds to being something that is not necessary; for example, virtues and vices, ugliness and beauty, health, and individual resemblance. Though triangle, and tetragon, each considered by itself, are not qualities; yet being “transformed into triangular appearance” is a quality; it is not therefore triangularity, but triangular formation, which is a quality. The same could be said of the arts and professions. Consequently, quality is a disposition, either adventitious or original, in already existing beings. Without it, however, being would exist just as much. It might be said that quality is either mutable or immutable; for it forms two kinds, according to whether it be permanent or changeable.	Tratado 17, 2
(Fifth objection): But how could (“seminal) reasons” be different in the conception of twins, and in the act of generation in the case of animals who procreate multiple offspring? Here it would seem that when the individuals are similar, there could be but one single “reason.” No so; for in that case there would not be so many “reasons” as there are individuals; and, on the contrary, it will have to be granted that there are as many as there are individuals that differ by specific differences, and not by a mere lack of form. Nothing therefore hinders us from admitting that there are different “reasons,” even for animal offspring which show no difference, if there were such. An artist who produces similar works cannot produce this resemblance without introducing in it some difference which depends on reasoning; so that every work he produces differs from the others, because he adds some difference to the similarity. In nature, where the difference does not derive from reasoning, but only from differing (“seminal) reasons” the (individual) difference will have to be added to the specific form, even though we may not be able to discern it. The (“seminal) reason” would be different if generation admitted chance as to quantity (the number of offspring begotten). But if the number of things to be born is determinate, the quantity will be limited by the evolution and development of all the “reasons,” so that, when the series of all things will be finished, another period may recommence. The quantity suitable to the world, and the number of beings who are to exist therein, are things regulated and contained in the principle which contains all the “reasons” (that is, the universal Soul), from the very beginning.	Tratado 18, 3
We will now, following (Plato), speak of another kind of assimilation as the privilege of a higher virtue. We will thus better understand the nature of homely virtues, and the higher virtues, and the difference between them. Plato is evidently distinguishing two kinds of virtues when he says that assimilation to the divinity consists in fleeing from (the world) here below; when he adds the qualification “homely” to the virtues relating to social life; and when in another place he asserts that all virtues are processes of purification; and it is not to the homely virtues that he attributes the power of assimilating us to the divinity.	Tratado 19, 3
It must be noticed that the expressions: “such a thing is present to such a thing” and “such a thing is in such other thing” have several meanings. Sometimes one thing improves or deteriorates some other thing by its presence, making it undergo a change; as may be seen in bodies, especially those of living beings. Again, one thing improves or deteriorates another without affecting it; this occurs with the soul, as we have already seen. Again, it is as when one impresses a figure on a piece of wax; the presence of the figure adds nothing to the (nature) of the wax, and its destruction makes it lose nothing. Likewise, light does not change the figure of the object which it enlightens with its rays. A cooled stone participates a little in the nature characteristic of the thing that cools it; but none the less remains stone. What suffering can light inflict on a line or a surface? One might perhaps say that in this case corporeal substance is affected; but how can it suffer (or be affected) by the action of light? Suffering, in fact, is not to enjoy the presence of something, nor to receive something. Mirrors, and, in general, transparent things, do not suffer (or are not affected) by the effect of images that form in them, and they offer a striking example of the truth we are here presenting. Indeed, qualities inhere in matter like simple images, and matter itself is more impassible than a mirror. Heat and cold occur in it without warming or cooling it; for heating and cooling consist in that one quality of the substrate gives place to another. In passing, we might notice that it would not be without interest to examine whether cold is not merely absence of heat. On entering into matter, qualities mostly react on each other only when they are opposite. What action, indeed, could be exercised by a smell on a sweet taste? By a color on a figure? How, in general, could things that belong to one genus act on another? This shows how one quality can give place to another in a same subject, or how one thing can be in another, without its presence causing any modification in the subject for which or in which it is present. Just as a thing is not altered by the first comer, likewise that which is affected and which changes does not receive a passive modification, or change, from any kind of an object. Qualities are affected only by the action of contraries. Things which are simply different cause no change in each other. Those which have no contraries could evidently not be modified by the action of any contrary. That which is affected, therefore, can not be matter; it must be a composite (of form and matter), or something multiple. But that which is isolated or separated from the rest, what is quite simple must remain impassible in respect of all things, and remain as a kind of medium in which other things may act on each other. Likewise, within a house, several objects can shock each other without the house itself or the air within it being affected. It is therefore qualities gathered in matter that act on each other, so far as it belongs to their nature. Matter itself, however, is still far more impassible than the qualities are among each other, when they do not find themselves opposite.	Tratado 26, 9
That is what seems true to us. As to the Philebus passage (quoted in the first section), it might mean that all souls were parts of the universal Soul. That, however, is not its true meaning, as held by some. It only means what Plato desired to assert in this place, namely, that heaven is animate. Plato proves this by saying that it would be absurd to insist that heaven has no soul, when our body, which is only a part of the body of the universe, nevertheless has a soul; but how could a part be animate, unless the whole was so also? It is especially in the Timaeus that Plato clearly expresses his thought. After having described the birth of the universal Soul, he shows the other souls born later from the mixture made in the same vase from which the universal Soul was drawn. He asserts that they are similar to the universal Soul, and that their difference consists in that they occupy the second or third rank. That is further confirmed by this passage of the Phaedrus: “The universal Soul cares for what is inanimate.” Outside of the Soul, indeed, what power would manage, fashion, ordain and produce the body? It would be nonsense to attribute this power to one soul, and not to another. (Plato) adds (in substance): “The Perfect Soul, the Soul of the universe, hovering in the ethereal region, acts on the earth without entering into it, being borne above him as in a chariot. The other souls that are perfect share with it the administration of the world.” When Plato speaks of the soul as having lost her wings, he is evidently distinguishing individual souls from the universal Soul. One might also conclude that our souls are part of the universal Soul from his statement that the souls follow the circular movement of the universe, that from it they derive their characteristics, and that they undergo its influence. Indeed, they might very easily undergo the influence exercised by the nature of the special localities, of the waters and the air of the towns they inhabit, and the temperament of the bodies to which they are joined. We have indeed acknowledged that, being contained in the universe, we possess something of the life-characteristic of the universal Soul, and that we undergo the influence of the circular movement of the heavens. But we have also shown that there is within us another (rational) soul, which is capable of resistance to these influences, and which manifests its different character precisely by the resistance she offers them. The objection that we are begotten within the universe may be answered by the fact that the child is likewise begotten within its mother’s womb, and that nevertheless the soul that enters into its body is distinct from that of its mother. Such is our solution of the problem.	Tratado 27, 7
(It is generally agreed that) all calamities, sufferings, griefs and similar evils are aggravated in proportion to their duration. If then, in all these cases, evil be increased with time, why should not the same circumstance obtain in the contrary case? Why should happiness also not be increased? Referring to griefs and sufferings, it might reasonably be said that they are increased by duration. When, for example, sickness is prolonged, and becomes a habitual condition, the body suffers more and more profoundly as time goes on. If, however, evil ever remain at the same degree, it does not grow worse, and there is no need of complaining but of the present. Consideration of the past evil amounts to considering the traces left by evil, the morbid disposition whose intensity is increased by time, because its seriousness is proportionate to its duration. In this case it is not the length of time, but the aggravation of the evil which adds to the misfortune. But the new degree (of intensity) does not subsist simultaneously with the old, and it is unreasonable to predicate an increase as summation of what is no more to what now is. On the contrary, it is the fixed characteristic of happiness to have a fixed term, to remain ever the same. Here also the only increase possibly due to duration of time depends on the relation between an increase in virtue and one in happiness; and the element to be reckoned with here is not the number of years of happiness, but the degree of virtue finally acquired.	Tratado 36, 6
Somebody might object that by subsisting till the present, the memory of the past adds something more to him who has long lived happily. In this case it will be necessary to examine what is meant by this memory. If it mean the memory of former wisdom, and if it mean that he who would possess this memory would become wiser on account of it, then this memory differs from our question (which studies happiness, and not wisdom). If it mean the memory of pleasure, it would imply that the happy man has need of much pleasure, and cannot remain satisfied with what is present. Besides, there is no proof that the memory of a past pleasure is at all pleasant; on the contrary, it would be entirely ridiculous to remember with delight having tasted a delicious dish the day before, and still more ridiculous remembering such an enjoyment ten years ago. It would be just as ridiculous to pride one self on having been a wise man last year.	Tratado 36, 8
Of which soul are these reasons, which do not beget the man (though they do beget the animal), then the actualization? Not of the vegetative soul; they are the actualizations of the (reasonable) soul which begets the animal, which is a more powerful, and therefore a more living soul. Man is constituted by the soul disposed in some manner, when present to matter disposed in some particular fashion — since the soul is some particular thing, according as she is in some particular disposition — even in the body. In the bodies, she fashions a resembling form. So far as the nature of the body allows it, she thus produces an image of the man, as the painter himself makes an image of the body; she produces, I repeat, an inferior man (the sense-man, the animal), which possesses the form of man, his reasons, morals, dispositions, faculties, although in an imperfect manner, because he is not the first man (the intellectual man). He has sensations of another kind; sensations which, though they seem clear, are obscure, if they be compared to the superior sensations of which they are the images. The superior man (the reasonable man) is better, has a diviner soul, and clearer sensations. It is he doubtless to whom Plato refers (when he says, Man is the soul); in his definition he adds, “which makes use of the body,” because the diviner man dominates the soul which uses the body, and thus uses the body only in an indirect manner.	Tratado 38, 5
The element of truth in all this, however, is that every action, disposition and life is joined by some accessory (pleasure or pain) that unites with it. Indeed, sometimes action meets an obstacle to its natural accomplishment, and life is affected by the mixture of a little of its contrary, which limits its independence; sometimes, however, action is produced without anything troubling its purity and serenity, and then life flows along a tranquil course. Those who consider that this state of intelligence is desirable, and preferable to everything else, in their inability to express their thoughts more definitely, say that it is mingled with pleasure. Such likewise is the meaning of expressions used by those who apply to divine things terms intended to express joy here below, and who say, “He is intoxicated with nectar! Let us to the banquet! Jupiter smiles!” This happy state of intelligence is that which is the most agreeable, the most worthy of our wishes, and of our love; nor is it transitory, and does not consist in a movement; its principle is that which colors intelligence, illumines it, and makes it enjoy a sweet serenity. That is why Plato adds to the mixture truth, and puts above it that which gives measure. He also adds that the proportion and the beauty which are in the mixture pass from there into the beautiful. That is the good that belongs to us, that is the fate that awaits us. That is the supreme object of desire, an object that we will achieve on condition of drawing ourselves up to that which is best in us. Now this thing full of proportion and beauty, this form composed (of the elements of which we have spoken), is nothing else but a life full of radiance, intelligence and beauty.	Tratado 38, 30

A quality is therefore a power which adds (essential) characteristics to already existing beings. These characteristics which differentiate beings can therefore be called qualities only figuratively. Qualities are, rather, actualizations and reasons, or parts of reasons, which proclaim the “whatness,” though the latter seem to qualify being. As to the qualities which really deserve this name, which “qualify” things, which we generally call “potentialities,” they are the reasons and shapes, either of the soul or the body, such as beauty or ugliness.	Tratado 42, 10
What part do the powers (or, potentialities) play here? The man who is naturally capable of boxing owes it to a certain disposition. It is so also with somebody who is unskilful in something. In general, quality consists in a non-essential characteristic; what seems to contribute to the being, or to add to it, as color, whiteness, and color in general, contributes to the beings as far as it constitutes something distinct therefrom, and is its actualization; but it occupies a rank inferior to being; and though derived therefrom, it adds itself thereto as something foreign, as an image and adumbration.	Tratado 42, 10
This was what Plato meant, when he said, enigmatically, “Intelligence contemplates the Ideas contained within the perfect living Organism; it sees what they are, and to how many they amount.” Indeed, the (universal) Soul, which ranks immediately after Intelligence, possesses the Ideas in herself inasmuch as she is a soul; but she sees them better in the Intelligence which is above her. Likewise, our own intelligence, which also contains the ideas, sees them better when it contemplates them in the superior Intelligence; for, in itself, it can only see; but in the superior Intelligence it sees that it sees. Now this intelligence that contemplates the ideas is not separated from the superior Intelligence, for it proceeds therefrom; but as it is the plurality that has proceeded from the unity, because it adds difference (to identity), it becomes manifold unity. Being thus both unity and plurality, Intelligence, by virtue of its multiple nature, produces the plurality (of beings). Besides, it would be impossible to discover therein anything that was numerically unitary, or anything that might be called individual. Whatever be contemplated in it, it is always a form, for it contains no matter. That is why, again, Plato, referring to this truth, said that “being” was divided to infinity. Descending from genus to species, we have not yet arrived at infinity; for that which thus arises is defined by the species that have been begotten by a genus; the name of infinity applies better to the last species, which can no longer be divided into species. That is why (as Plato teaches), “when one has arrived at individuals, they must be abandoned to infinity.” Thus, the individuals are infinite so far as they are considered in themselves; but, in so far as they are embraced by unity, they are reduced to a number.	Tratado 43, 22
It may still be objected that it is not matter that makes us wicked; for it is not matter that produces ignorance and perverted appetites. If, indeed, these appetites mislead us to evil as a result of the perversity of the body, we must seek its cause, not in matter, but in form (in the qualities of the bodies). These, for instance, are heat, cold, bitterness, pungency, and the other qualities of the bodily secretions; or, the atonic condition or inflammation of certain organs; or, certain dispositions which produce the difference of appetites; and, if you please, false opinions. Evil, therefore, is form rather than matter. Even under this (mistaken) hypothesis we are none the less driven to acknowledge that matter is the evil. A quality does not always produce the same results within or outside of matter; thus the form of the axe without iron does not cut. The forms that inhere in matter are not always what they would be if they were outside of it. The (“seminal) reasons” when inhering in matter are by it corrupted and filled with its nature. As fire, when separate from matter, does not burn; so form, when remaining by itself, effects what it would if it were in matter. Matter dominates any principle that appears within it, alters it, and corrupts it by imparting thereto its own nature, which is contrary to the Good. It does not indeed substitute cold for heat, but it adds to the form — as, for instance, to the form of fire — its formless substance; to figure adding its shapelessness; to measure, its excess and lack, proceeding thus until it has degraded things, transubstantiating them into its own nature. That is the reason that, in the nutrition of animals, what has been ingested does not remain what it was before. The foods that enter into the body of a dog, for instance, are by assimilation transformed into blood and canine secretions, and, in general, are transformed according to the animal that receives them. Thus even under the hypothesis that evils are referred to the body, matter is the cause of evils.	Tratado 51, 8
When we attribute infallibility to the soul, we are supposing her to be one and simple, identifying the soul with soul essence. When, however, we consider her capable of sin, we are looking at her as a complex, of her essence and of another kind of soul which can experience brutal passions. The soul, thus, is a combination of various elements; and it is not the pure soul, but this combination, which experiences passions, commits sins, and undergoes punishments. It was this conception of the soul Plato was referring to when he said:313 “We see the soul as we see Glaucus, the marine deity,” and he adds, “He who would know the nature of the soul herself should, after stripping her of all that is foreign to her, in her, especially consider her philosophic love for truth; and see to what things she attaches herself, and by virtue of whose affinities she is what she is.” We must, therefore, differentiate the soul’s life acts from that which is punished, and when we speak of philosophy’s separation of the soul, we mean a detaching not only from the body, but also from what has been added to the soul.	Tratado 53, 12
