Part II of three parts, showing life begins at conception. Do your homework and review first, or else these arguments seem to come out of the blue.
Chapter 83 That the human soul begins to exist when the body does (alternate translation) We’re still using the alternate translation.
16 Then, too, whatever is subject to alternate phases of existence according to various periods of time is subject to the movement of the heaven, which the whole course of time follows. But intellectual and incorporeal substances, including separately existing souls, transcend the entire realm of bodily things. Hence, they cannot be subject to the movements of the heavenly bodies. Therefore, it is impossible that they should be naturally united during one period of time and separated during another, or that they should naturally desire this at one time, and that at another.
17 On the other hand, the hypothesis that souls are united to bodies neither by violence nor by nature, but by free choice, is likewise impossible. For no one voluntarily enters into a state worse than the previous one, unless he be deceived.
But the separate soul enjoys a higher state of existence than when united to the body; especially according to the Platonists, who say that through its union with the body, the soul forgets what it knew before, its power to contemplate truth in a pure manner thus being checked. Hence, the soul is not willingly united to the body unless it be the victim of deception. But there can be nothing in the soul that could cause deception, since, for the Platonists, the soul is possessed of all knowledge. Nor can it be said that the soul’s judgment, proceeding from universal scientific knowledge and applied to a particular matter of choice, is overwhelmed by the passions, as in the incontinent; for no passions of this sort occur without bodily change, and, consequently, they cannot exist in the separate soul. We are, then, left with the conclusion that, if the soul had existed before the body, it would not be united to the body of its own will.
Notes Sin is explained in that first bit, too.
18 Moreover, every effect issuing from the concurrent operation of two mutually unrelated wills is fortuitous, as in the case of a person who goes out to shop and meets his creditor in the market place without any prior arrangement between the two. Now, the will of the generative agent, whereon the body’s production depends, is independent of the will of the separate soul which wills to be united. It follows that the union of the soul and body is fortuitous, since it cannot be effected without the concurrence of both wills. Thus, the begetting of a man results not from nature, but from chance, which is patently false, since it occurs in the majority of cases.
Note And this is more proof chance is in your mind, not things.
19 Now, again, the theory may be advanced that the soul is united to the body by divine decree, and not by nature, nor of its own will. But such a supposition also seems inadmissitesble on the hypothesis that souls were created before bodies. For God established each thing in being in a mode congruent with its nature. Hence, in the Book of Genesis (1:10, 31) it is said of each creature: “God saw that it was good,” and of all creatures collectively: “God saw all the things that He had made, and they were very good.”
If, then, God created souls separate from bodies, it must be said that this manner of being is more suitable to their nature. But it is not becoming to the ordering of things by the divine goodness to relegate them to a lower state, but, rather, to raise them to a higher. Hence, it could not have been by God’s ordinance that the soul was united to the body.
20 Moreover, it is inconsistent with the order of divine wisdom to raise up lower things to the detriment of higher things. But generable and corruptible bodies have the lowest rank in the order of things. Hence, it would not have been consistent with the order of divine wisdom to ennoble human bodies by uniting pre-existing souls to them, since this would be impossible without detriment to the latter, as we have already seen.
21 Having this point in mind—for he asserted that human souls had been created from the beginning—Origen said that they were united to bodies by divine decree, but as a punishment. For Origen thought that souls had sinned before bodies existed, and that according to the gravity of their sin, souls were shut up in bodies of higher or lower character, as in so many prisons.
Notes A fallacy, but an understandable one!
22 This doctrine, however, is untenable, for, being contrary to a good of nature, punishment is said to be an evil. If, then, the union of soul and body is something penal in character, it is not a good of nature. But this is impossible, for that union is intended by nature, since natural generation terminates in it. And again, on Origen’s theory, it would follow that man’s being would not be a good according to nature, yet it is said, after man’s creation: “God saw all the things that He had made, and they were very good.”
23 Furthermore, good does not issue from evil save by accident. Therefore, if the soul’s union with the body were due to sin on the part of the separate soul, it would follow that this union is accidental, since it is a kind of good. In that case the production of man was a matter of chance. But such a thing is derogatory to God’s wisdom, of which it is written that “It ordered all things in number, weight, and measure” (Wis. 11:21).
24 That notion also clearly clashes with apostolic doctrine. For St. Paul says of Jacob and Esau, that “when they were not yet born, nor had done any good or evil, it was said that the elder shall serve the younger” (Rom. 9:11-17). Hence, before this was said, their souls had not sinned at all, yet the Apostle’s statement postdates the time of their conception, as Genesis (25:23) makes clear.
25 Earlier, in treating of the distinction of things, we leveled against Origen’s position a number of arguments which may also be used here. Omitting them, therefore, we pass on to others.
26 It must be said that the human soul either needs the senses or does not need them. Now, experience seems to show clearly that the former is true. For a person who lacks a certain sense has no knowledge of the sensible objects which are perceived through that sense; a man born blind has neither knowledge nor any understanding of colors.
Furthermore, if the human soul does not require the senses in order to understand, then sensitive and intellective cognition in man would have so ordered relationship to one another. But experience demonstrates the contrary; for our senses give rise to memories, and from these we obtain experiential knowledge of things, which in turn is the means through which we come to an understanding of the universal principles of sciences and arts.
Now, nature is wanting in nothing that is necessary for the fulfillment of its proper operation; thus, to animals whose soul is endowed with powers of sense and movement nature gives the appropriate organs of sense and movement. Hence, if the human soul needs the senses in order to understand, then that soul would never have been made to be in the first place without the indispensable assistants which the senses are. But the senses do not function without corporeal organs, as we have seen. The soul, therefore, was not made without such organs.
27 The argument that the human soul does not need the senses in order to understand, and thus is said to have been created apart from the body, necessarily implies that, before being united to the body, the soul was by itself cognizant of all scientific truths.
The Platonists indeed admitted this in saying that Ideas, which according to Plato are the separate intelligible forms of things, are the cause of knowledge; and thus, the separate soul, having no obstacle confronting it, received full knowledge of all sciences. Therefore, since the soul is found to be ignorant when united to the body, it must be said that it forgets the knowledge which it previously possessed.
The Platonists acknowledge this inference, also, adducing the following observation as indicative of its truth: If a man, however ignorant he may be, is questioned systematically about matters taught in the sciences, he will answer the truth; so, if a man has forgotten some of the things that he knew before, and a person proposes to him one by one the things he has forgotten, he recalls them to his memory. And from this they inferred that learning was nothing else than remembering.
This theory then necessarily led to the conclusion that union with the body places an obstacle in the way of the soul’s understanding. In no case, however, does nature unite a thing to that which impedes its operation; on the contrary, nature unites the thing to that which facilitates its operation. Thus, the union of body and soul will not be natural, so that man will not be a natural thing, nor will his engendering be natural; which, of course, is false.
Notes That learning is not recollection is proved in wading through this arguments, especially if it your first time!
28 The ultimate end of every thing, moreover, is that which it strives to attain by its operations. But man, by all his proper operations fittingly ordered and rightly directed, strives to attain the contemplation of truth; for the operations of the active powers are certain preparations and dispositions to the contemplative powers. The end of man, therefore, is to arrive at the contemplation of truth. It is for this purpose, then, that the soul is united to the body, and in this union does man’s being consist. Therefore, it is not union with the body that causes the soul to lose knowledge which it had possessed; on the contrary, the soul is united to the body so that it may acquire knowledge.
29 Then, too, if a person ignorant of the sciences is questioned about matters pertaining to the sciences, his answers will not be true, except with regard to the universal principles of which no one is ignorant, but which are known by all in the same way and naturally. But, if that ignorant person is questioned systematically later on, he will answer truly concerning matters closely related to the principles, by referring them to the latter; and he will go on answering truly as long as he is able to apply the power of first principles to the subjects about which he is questioned.
This makes it quite clear, therefore, that through the primary principles new knowledge is caused in the person questioned. This new knowledge, then, is not caused by recalling to memory things previously known.
Notes I’ve heard it said the highest form of reasoning is not forming analogies, but analogies between analogies.
