[¶0] Chapter 6.—How a Kind of Trinity Exists in the Mind Thinking of Itself. What is the Part of Thought in This Trinity.

[¶1] The function of thought, however, is so great, that not even the mind itself can, so to say, place itself in its own sight, except when it thinks of itself; and hence it is so far the case, that nothing is in the sight of the mind, except that which is being thought of, that not even the mind itself, whereby we think whatever we do think, can be in its own sight otherwise than by thinking of itself. But in what way it is not in its own sight when it is not thinking of itself, while it can never be without itself, as though itself were one thing, and the sight of itself another, it is not in my power to discover. For this is not unreasonably said of the eye of the body; for the eye itself of the body is fixed in its own proper place in the body, but its sight extends to things external to itself, and reaches even to the stars. And the eye is not in its own sight, since it does not look at itself, unless by means of a mirror, as is said above; a thing that certainly does not happen when the mind places itself in its own sight by thinking of itself. Does it then see one part of itself by means of another part of itself, when it looks at itself in thought, as we look at some of our members, which can be in our sight, with other also of our members, viz. with our eyes? What can be said or thought more absurd? For by what is the mind removed, except by itself? or where is it placed so as to be in its own sight, except before itself? Therefore it will not be there, where it was, when it was not in its own sight; because it has been put down in one place, after being taken away from another. But if it migrated in order to be beheld, where will it remain in order to behold? Is it as it were doubled, so as to be in this and in that place at the same time, viz. both where it can behold, and where it can be beheld; that in itself it may be beholding, and before itself beheld? If we ask the truth, it will tell us nothing of the sort since it is but feigned images of bodily objects of which we conceive when we conceive thus; and that the mind is not such, is very certain to the few minds by which the truth on such a subject can be inquired. It appears, therefore, that the beholding of the mind is something pertaining to its nature, and is recalled to that nature when it conceives of itself, not as if by moving through space, but by an incorporeal conversion; but when it is not conceiving of itself, it appears that it is not indeed in its own sight, nor is its own perception formed from it, but yet that it knows itself as though it were to itself a remembrance of itself. Like one who is skilled in many branches of learning: the things which he knows are contained in his memory, but nothing thereof is in the sight of his mind except that of which he is conceiving; while all the rest are stored up in a kind of secret knowledge, which is called memory. The trinity, then, which we were setting forth, was constituted in this way: first, we placed in the memory the object by which the perception of the percipient was formed; next, the conformation, or as it were the image which is impressed thereby; lastly, love or will as that which combines the two. When the mind, then, beholds itself in conception, it understands and cognizes itself; it begets, therefore, this its own understanding and cognition. For an incorporeal thing is understood when it is beheld, and is cognized when understood. Yet certainly the mind does not so beget this knowledge of itself, when it beholds itself as understood by conception, as though it had before been unknown to itself; but it was known to itself, in the way in which things are known which are contained in the memory, but of which one is not thinking; since we say that a man knows letters even when he is thinking of something else, and not of letters. And these two, the begetter and the begotten, are coupled together by love, as by a third, which is nothing else than will, seeking or holding fast the enjoyment of something. We held, therefore, that a trinity of the mind is to be intimated also by these three terms, memory, intelligence, will.

[¶2] 9. But since the mind, as we said near the end of the same tenth book, always remembers itself, and always understands and loves itself, although it does not always think of itself as distinguished from those things which are not itself; we must inquire in what way understanding (intellectus) belongs to conception, while the notion (notitia) of each thing that is in the mind, even when one is not thinking of it, is said to belong only to the memory. For if this is so, then the mind had not these three things: viz. the remembrance, the understanding, and the love of itself; but it only remembered itself, and afterwards, when it began to think of itself, then it understood and loved itself.

### The Thing is Made Plain by an Example. In What Way the Matter is Handled in Order to Help the Reader

[¶4] Chapter 7.—The Thing is Made Plain by an Example. In What Way the Matter is Handled in Order to Help the Reader.

[¶5] Wherefore let us consider more carefully that example which we have adduced, wherein it was shown that not knowing a thing is different from not thinking [conceiving] of it; and that it may so happen that a man knows something of which he is not thinking, when he is thinking of something else, not of that. When any one, then, who is skilled in two or more branches of knowledge is thinking of one of them, though he is not thinking of the other or others, yet he knows them. But can we rightly say, This musician certainly knows music, but he does not now understand it, because he is not thinking of it; but he does now understand geometry, for of that he is now thinking? Such an assertion, as far as appears, is absurd. What, again, if we were to say, This musician certainly knows music, but he does not now love it, while he is not now thinking of it; but he does now love geometry, because of that he is now thinking,—is not this similarly absurd? But we say quite correctly, This person whom you perceive disputing about geometry is also a perfect musician, for he both remembers music, and understands, and loves it; but although he both knows and loves it, he is not now thinking of it, since he is thinking of geometry, of which he is disputing. And hence we are warned that we have a kind of knowledge of certain things stored up in the recesses of the mind, and that this, when it is thought of, as it were, steps forth in public, and is placed as if openly in the sight of the mind; for then the mind itself finds that it both remembers, and understands, and loves itself, even although it was not thinking of itself, when it was thinking of something else. But in the case of that of which we have not thought for a long time, and cannot think of it unless reminded; that, if the phrase is allowable, in some wonderful way I know not how, we do not know that we know. In short, it is rightly said by him who reminds, to him whom he reminds, You know this, but you do not know that you know it; I will remind you, and you will find that you know what you had thought you did not know. Books, too, lead to the same results, viz. those that are written upon subjects which the reader under the guidance of reason finds to be true; not those subjects which he believes to be true on the faith of the narrator, as in the case of history; but those which he himself also finds to be true, either of himself, or in that truth itself which is the light of the mind. But he who cannot contemplate these things, even when reminded, is too deeply buried in the darkness of ignorance, through great blindness of heart and too wonderfully needs divine help, to be able to attain to true wisdom.

[¶6] 10. For this reason I have wished to adduce some kind of proof, be it what it might, respecting the act of conceiving, such as might serve to show in what way, out of the things contained in the memory, the mind’s eye is informed in recollecting, and some such thing is begotten, when a man conceives, as was already in him when, before he conceived, he remembered; because it is easier to distinguish things that take place at successive times, and where the parent precedes the offspring by an interval of time. For if we refer ourselves to the inner memory of the mind by which it remembers itself, and to the inner understanding by which it understands itself, and to the inner will by which it loves itself, where these three always are together, and always have been together since they began to be at all, whether they were being thought of or not; the image of this trinity will indeed appear to pertain even to the memory alone; but because in this case a word cannot be without a thought (for we think all that we say, even if it be said by that inner word which belongs to no separate language), this image is rather to be discerned in these three things, viz. memory, intelligence, will. And I mean now by intelligence that by which we understand in thought, that is, when our thought is formed by the finding of those things, which had been at hand to the memory but were not being thought of; and I mean that will, or love, or preference which combines this offspring and parent, and is in some way common to both. Hence it was that I tried also, viz. in the eleventh book, to lead on the slowness of readers by means of outward sensible things which are seen by the eyes of the flesh; and that I then proceeded to enter with them upon that power of the inner man whereby he reasons of things temporal, deferring the consideration of that which dominates as the higher power, by which he contemplates things eternal. And I discussed this in two books, distinguishing the two in the twelfth, the one of them being higher and the other lower, and that the lower ought to be subject to the higher; and in the thirteenth I discussed, with what truth and brevity I could, the office of the lower, in which the wholesome knowledge of things human is contained, in order that we may so act in this temporal life as to attain that which is eternal; since, indeed, I have cursorily included in a single book a subject so manifold and copious, and one so well known by the many and great arguments of many and great men, while manifesting that a trinity exists also in it, but not yet one that can be called an image of God.

### The Trinity Which is the Image of God is Now to Be Sought in the Noblest Part of the Mind

[¶8] Chapter 8.—The Trinity Which is the Image of God is Now to Be Sought in the Noblest Part of the Mind.

[¶9] 11. But we have come now to that argument in which we have undertaken to consider the noblest part of the human mind, by which it knows or can know God, in order that we may find in it the image of God. For although the human mind is not of the same nature with God, yet the image of that nature than which none is better, is to be sought and found in us, in that than which our nature also has nothing better. But the mind must first be considered as it is in itself, before it becomes partaker of God; and His image must be found in it. For, as we have said, although worn out and defaced by losing the participation of God, yet the image of God still remains. For it is His image in this very point, that it is capable of Him, and can be partaker of Him; which so great good is only made possible by its being His image. Well, then, the mind remembers, understands, loves itself; if we discern this, we discern a trinity, not yet indeed God, but now at last an image of God. The memory does not receive from without that which it is to hold; nor does the understanding find without that which it is to regard, as the eye of the body does; nor has will joined these two from without, as it joins the form of the bodily object and that which is thence wrought in the vision of the beholder; nor has conception, in being turned to it, found an image of a thing seen without, which has been somehow seized and laid up in the memory, whence the intuition of him that recollects has been formed, will as a third joining the two: as we showed to take place in those trinities which were discovered in things corporeal, or which were somehow drawn within from bodily objects by the bodily sense; of all which we have discoursed in the eleventh book. Nor, again, as it took place, or appeared to do so, when we went on further to discuss that knowledge, which had its place now in the workings of the inner man, and which was to be distinguished from wisdom; of which knowledge the subject-matter was, as it were, adventitious to the mind, and either was brought thither by historical information,—as deeds and words, which are performed in time and pass away, or which again are established in the nature of things in their own times and places,—or arises in the man himself not being there before, whether on the information of others, or by his own thinking,—as faith, which we commended at length in the thirteenth book, or as the virtues, by which, if they are true, one so lives well in this mortality as to live blessedly in that immortality which God promises. These and other things of the kind have their proper order in time, and in that order we discerned more easily a trinity of memory, sight, and love. For some of such things anticipate the knowledge of learners. For they are knowable also before they are known, and beget in the learner a knowledge of themselves. And they either exist in their own proper places, or have happened in time past; although things that are past do not themselves exist, but only certain signs of them as past, the sight or hearing of which makes it known that they have been and have passed away. And these signs are either situate in the places themselves, as e.g. monuments of the dead or the like; or exist in written books worthy of credit, as is all history that is of weight and approved authority; or are in the minds of those who already know them; since what is already known to them is knowable certainly to others also, whose knowledge it has anticipated, and who are able to know it on the information of those who do know it. And all these things, when they are learned, produce a certain kind of trinity, viz. by their own proper species, which was knowable also before it was known, and by the application to this of the knowledge of the learner, which then begins to exist when he learns them, and by will as a third which combines both; and when they are known, yet another trinity is produced in the recollecting of them, and this now inwardly in the mind itself, from those images which, when they were learned, were impressed upon the memory, and from the informing of the thought when the look has been turned upon these by recollection, and from the will which as a third combines these two. But those things which arise in the mind, not having been there before, as faith and other things of that kind, although they appear to be adventitious, since they are implanted by teaching, yet are not situate without or transacted without, as are those things which are believed; but began to be altogether within in the mind itself. For faith is not that which is believed, but that by which it is believed; and the former is believed, the latter seen. Nevertheless, because it began to be in the mind, which was a mind also before these things began to be in it, it seems to be somewhat adventitious, and will be reckoned among things past, when sight shall have succeeded, and itself shall have ceased to be. And it makes now by its presence, retained as it is, and beheld, and loved, a different trinity from that which it will then make by means of some trace of itself, which in passing it will have left in the memory: as has been already said above.

### Whether Justice and the Other Virtues Cease to Exist in the Future Life

[¶11] Chapter 9.—Whether Justice and the Other Virtues Cease to Exist in the Future Life.

[¶12] 12. There is, however, some question raised, whether the virtues likewise by which one lives well in this present mortality, seeing that they themselves begin also to be in the mind, which was a mind none the less when it existed before without them, cease also to exist at that time when they have brought us to things eternal. For some have thought that they will cease, and in the case of three—prudence, fortitude, temperance—such an assertion seems to have something in it; but justice is immortal, and will rather then be made perfect in us than cease to be. Yet Tullius, the great author of eloquence, when arguing in the dialogue Hortensius, says of all four: “If we were allowed, when we migrated from this life, to live forever in the islands of the blessed, as fables tell, what need were there of eloquence when there would be no trials, or what need, indeed, of the very virtues themselves? For we should not need fortitude when nothing of either toil or danger was proposed to us; nor justice, when there was nothing of anybody else’s to be coveted; nor temperance, to govern lusts that would not exist; nor, indeed, should we need prudence, when there was no choice offered between good and evil. We should be blessed, therefore, solely by learning and knowing nature, by which alone also the life of the gods is praiseworthy. And hence we may perceive that everything else is a matter of necessity, but this is one of free choice.” This great orator, then, when proclaiming the excellence of philosophy, going over again all that he had learned from philosophers, and excellently and pleasantly explaining it, has affirmed all four virtues to be necessary in this life only, which we see to be full of troubles and mistakes; but not one of them when we shall have migrated from this life, if we are permitted to live there where is a blessed life; but that blessed souls are blessed only in learning and knowing, i.e. in the contemplation of nature, than which nothing is better and more lovable. It is that nature which created and appointed all other natures. And if it belongs to justice to be subject to the government of this nature then justice is certainly immortal; nor will it cease to be in that blessedness, but will be such and so great that it cannot be more perfect or greater. Perhaps, too, the other three virtues—prudence although no longer with any risk of error, and fortitude without the vexation of bearing evils, and temperance without the thwarting of lust—will exist in that blessedness: so that it may be the part of prudence to prefer or equal no good thing to God; and of fortitude, to cleave to Him most steadfastly; and of temperance, to be pleased by no harmful defect. But that which justice is now concerned with in helping the wretched, and prudence in guarding against treachery, and fortitude in bearing troubles patiently, and temperance in controlling evil pleasures, will not exist there, where there will be no evil at all. And hence those acts of the virtues which are necessary to this mortal life, like the faith to which they are to be referred, will be reckoned among things past; and they make now a different trinity, whilst we hold, look at, and love them as present, from that which they will then make, when we shall discover them not to be, but to have been, by certain traces of them which they will have left in passing in the memory; since then, too, there will be a trinity, when that trace, be it of what sort it may, shall be retained in the memory, and truly recognized, and then these two be joined by will as a third.

### How a Trinity is Produced by the Mind Remembering, Understanding, and Loving Itself

[¶14] Chapter 10.—How a Trinity is Produced by the Mind Remembering, Understanding, and Loving Itself.

[¶15] 13. In the knowledge of all these temporal things which we have mentioned, there are some knowable things which precede the acquisition of the knowledge of them by an interval of time, as in the case of those sensible objects which were already real before they were known, or of all those things that are learned through history; but some things begin to be at the same time with the knowing of them,—just as, if any visible object, which did not exist before at all, were to rise up before our eyes, certainly it does not precede our knowing it; or if there be any sound made where there is some one to hear, no doubt the sound and the hearing that sound begin and end simultaneously. Yet none the less, whether preceding in time or beginning to exist simultaneously, knowable things generate knowledge, and are not generated by knowledge. But when knowledge has come to pass, whenever the things known and laid up in memory are reviewed by recollection, who does not see that the retaining them in the memory is prior in time to the sight of them in recollection, and to the uniting of the two things by will as a third? In the mind, howver, it is not so. For the mind is not adventitious to itself, as though there came to itself already existing, that same self not already existing, from somewhere else, or did not indeed come from somewhere else, but that in the mind itself already existing, there was born that same mind not already existing; just as faith, which before was not, arises in the mind which already was. Nor does the mind see itself, as it were, set up in its own memory by recollection subsequently to the knowing of itself, as though it was not there before it knew itself; whereas, doubtless, from the time when it began to be, it has never ceased to remember, to understand, and to love itself, as we have already shown. And hence, when it is turned to itself by thought, there arises a trinity, in which now at length we can discern also a word; since it is formed from thought itself, will uniting both. Here, then, we may recognize, more than we have hitherto done, the image of which we are in search.

### Whether Memory is Also of Things Present

[¶17] Chapter 11.—Whether Memory is Also of Things Present.

[¶18] 14. But some one will say, That is not memory by which the mind, which is ever present to itself, is affirmed to remember itself; for memory is of things past, not of things present. For there are some, and among them Cicero, who, in treating of the virtues, have divided prudence into these three—memory, understanding, forethought: to wit, assigning memory to things past, understanding to things present, forethought to things future; which last is certain only in the case of those who are prescient of the future; and this is no gift of men, unless it be granted from above, as to the prophets. And hence the book of Wisdom, speaking of men, “The thoughts of mortals,” it says, “are fearful, and our forethought uncertain.” But memory of things past, and understanding of things present, are certain: certain, I mean, respecting things incorporeal, which are present; for things corporeal are present to the sight of the corporeal eyes. But let any one who denies that there is any memory of things present, attend to the language used even in profane literature, where exactness of words was more looked for than truth of things. “Nor did Ulysses suffer such things, nor did the Ithacan forget himself in so great a peril.” For when Virgil said that Ulysses did not forget himself, what else did he mean, except that he remembered himself? And since he was present to himself, he could not possibly remember himself, unless memory pertained to things present. And, therefore, as that is called memory in things past which makes it possible to recall and remember them; so in a thing present, as the mind is to itself, that is not unreasonably to be called memory, which makes the mind at hand to itself, so that it can be understood by its own thought, and then both be joined together by love of itself.

### The Trinity in the Mind is the Image of God, in that It Remembers, Understands, and Loves God, Which to Do is Wisdom

[¶20] Chapter 12.—The Trinity in the Mind is the Image of God, in that It Remembers, Understands, and Loves God, Which to Do is Wisdom.

[¶21] 15. This trinity, then, of the mind is not therefore the image of God, because the mind remembers itself, and understands and loves itself; but because it can also remember, understand, and love Him by whom it was made. And in so doing it is made wise itself. But if it does not do so, even when it remembers, understands, and loves itself, then it is foolish. Let it then remember its God, after whose image it is made, and let it understand and love Him. Or to say the same thing more briefly, let it worship God, who is not made, by whom because itself was made, it is capable and can be partaker of Him; wherefore it is written, “Behold, the worship of God, that is wisdom.” And then it will be wise, not by its own light, but by participation of that supreme Light; and wherein it is eternal, therein shall reign in blessedness. For this wisdom of man is so called, in that it is also of God. For then it is true wisdom; for if it is human, it is vain. Yet not so of God, as is that wherewith God is wise. For He is not wise by partaking of Himself, as the mind is by partaking of God. But as we call it the righteousness of God, not only when we speak of that by which He Himself is righteous, but also of that which He gives to man when He justifies the ungodly, which latter righteousness the apostle commending, says of some, that “not knowing the righteousness of God and going about to establish their own righteousness, they are not subject to the righteousness of God;” so also it may be said of some, that not knowing the wisdom of God and going about to establish their own wisdom, they are not subject to the wisdom of God.

[¶22] 16. There is, then, a nature not made, which made all other natures, great and small, and is without doubt more excellent than those which it has made, and therefore also than that of which we are speaking; viz. than the rational and intellectual nature, which is the mind of man, made after the image of Him who made it. And that nature, more excellent than the rest, is God. And indeed “He is not far from every one of us,” as the apostle says, who adds, “For in Him we live, and are moved, and have our being.” And if this were said in respect to the body, it might be understood even of this corporeal world; for in it too in respect to the body, we live, and are moved, and have our being. And therefore it ought to be taken in a more excellent way, and one that is spiritual, not visible, in respect to the mind, which is made after His image. For what is there that is not in Him, of whom it is divinely written, “For of Him, and through Him, and in Him, are all things”? If, then, all things are in Him, in whom can any possibly live that do live, or be moved that are moved, except in Him in whom they are? Yet all are not with Him in that way in which it is said to Him, “I am continually with Thee.” Nor is He with all in that way in which we say, The Lord be with you. And so it is the especial wretchedness of man not to be with Him, without whom he cannot be. For, beyond a doubt, he is not without Him in whom he is; and yet if he does not remember, and understand, and love Him, he is not with Him. And when any one absolutely forgets a thing, certainly it is impossible even to remind him of it.
