8. R. Define therefore the True. A. That is true which is so as it appears to the knower, if he will and can know. R. That therefore will not be true which no one can know? Then, if that is false which seems otherwise than it is; how if to one this stone should seem a stone, to another wood? will the same thing be both false and true? A. That former position disturbs me more, how, if anything cannot be known, it results from that that it is not true. For as to this, that one thing is both true and false, I do not much care. For I see one thing, compared with diverse things, to be both greater and smaller. From which it results, that nothing is more or less of itself. For these are terms of comparison. R. But if you say that nothing is true of itself, do you not fear the inference, that nothing is of itself? For whereby this is wood, thereby is it also true wood. Nor can it be, that of itself, that is, without a knower, it should be wood, and should not be true wood. A. Therefore thus I say and so I define, nor do I fear lest my definition be disapproved on the ground of excessive brevity: for to me that seems to be true which is. R. Nothing then will be false, because whatever is, is true. A. Thou hast driven me into close straits, and I am wholly unprovided of an answer. So it comes to pass that whereas I am unwilling to be taught except by these questionings, I fear now to be questioned.
9. R. God, to whom we have commended ourselves, without doubt will render help, and set us free from these straits, if only we believe, and entreat Him most devoutly. A. Nothing, assuredly, would I do more gladly in this place; for never have I been involved in so great a darkness. God, Our Father, who exhortest us to pray, who also bringest this about, that supplication is made to Thee; since when we make supplication to Thee, we live better, and are better: hear me groping in these glooms, and stretch forth Thy right hand to me. Shed over me Thy light, revoke me from my wanderings; bring Thyself into me that I may likewise return into Thee. Amen. R. Be with me now, as far as thou mayest, in most diligent attention. A. Utter, I pray, whatever has been suggested to thee, that we perish not. R. Give heed. A. Behold, I have neither eyes nor ears but for thee.
10. R. First let us again and yet again ventilate this question, What is falsity? A. I wonder if there will turn out to be anything, except what is not so as it seems. R. Give heed rather, and let us first question the senses themselves. For certainly what the eyes see, is not called false, unless it have some similitude of the true. For instance, a man whom we see in sleep, is not indeed a true man, but false, by this very fact that he has the similitude of a true one. For who, seeing a dog, would have a right to say that he had dreamed of a man? Therefore too that is thereby a false dog, that it is like a true one. A. It is as thou sayest. R. And moreover, if any one waking should see a horse and think he saw a man, is he not hereby misled, that there appears to him some similitude of a man? For if nothing should appear to him except the form of a horse, he cannot think that he sees a man. A. I fully concede this. R. We call that also a false tree which we see in a picture, and a false face which is reflected from a mirror, and a false motion of buildings to men that are sailing from them, and a false break in the oar when dipped, for no other reason than the verisimilitude in all these things. A. True. R. So we make mistakes between twins, so between eggs, so between seals stamped by one ring, and other such things. A. I follow and agree to all. R. Therefore that similitude of things which pertains to the eyes, is the mother of falsity. A. I cannot deny it.
11. R. But all this forest of facts, unless I am mistaken, may be divided into two kinds. For it lies partly in equal, partly in inferior things. They are equal, when we say that this is as like to that as that to this, as is said of twins, or impressions of a ring. Inferior, when we say that the worse is like the better. For who, looking in a mirror, would dream of saying that he is like that image, and not rather that like him? And this class consists partly in what the soul undergoes, and partly in those things which are seen. And that again which the soul undergoes, it either undergoes in the sense, as the unreal motion of a building; or in itself from that which it has received from the senses, such as are the dreams of dreamers, and perhaps also of madmen. Furthermore, those things which appear in the things themselves which we see, are some of them from nature, and some expressed and framed by living creatures. Nature either by procreation or reflection effects inferior similitudes. By procreation, when to parents children like them are born; by reflection, as from mirrors of various kinds. For although it is men that make the most of the mirrors, yet it is not they that frame the images given back. On the other hand, the works of living creatures are seen in pictures, and creations of the like kind: in which may also be included (conceding their occurrence) those things which demons produce. But the shadows of bodies, because with but a slight stretch of language they may be described as like their bodies and a sort of false bodies, nor can be disputed to be submitted to the judgment of the eyes, may reasonably be placed in that class, which are brought about by nature through reflection. For every body exposed to the light reflects, and casts a shadow in the opposite direction. Or do you see any objection to be made? A. None. I am only awaiting anxiously the issue of these illustrations.
12. R. We must, however, wait patiently, until the remaining senses also make report to us that falsity dwells in the similitude of the true. For in the sense of hearing likewise there are almost as many sorts of similitudes: as when, hearing the voice of a speaker, whom we do not see, we think it some one else, whom in voice he resembles; and in inferior similitudes Echo is a witness, or that well-known roaring of the ears themselves, or in timepieces a certain imitation of thrush or crow, or such things as dreamers or lunatics imagine themselves to hear. And it is incredible how much false tones, as they are called by musicians, bear witness to the truth, which will appear hereinafter: yet they too (which will suffice just now) are not remote from a resemblance to those which men call true. Do you follow this? A. And most delightedly. For here I have no trouble to understand. R. Then, to press on, do you think it is easy, by the smell, to distinguish lily from lily, or by the taste honey from honey, gathered alike from thyme, though brought from different hives, or by the touch to note the difference between the softness of the plumage of the goose and of the swan? A. It does not seem easy. R. And how is it when we dream that we either smell or taste, or touch such things? Are we not then deceived by a similitude of effects and images, inferior in proportion to its emptiness? A. Thou speakest truly. R. Therefore it appears that we, in all our senses, whether by equality or inferiority of likeness, are either misled by cozening similitude, or even if we are not misled, as suspending our consent, or discovering the difference, yet that we name those things false which we apprehend as like the true. A. I cannot doubt it.
13. R. Now give heed, while we run over the same things once more, that what we are endeavoring to show may come more plainly to view. A. Lo, here I am, speak what thou wilt. For I have once for all resolved to endure this circuitous course, nor will I be wearied out in it, hoping so ardently to arrive at length whither I perceive that we are tending. R. You do well. But take note whether it seems to you, when we see a resemblance in eggs, that we can justly say that any one of them is false. A. Far from it. For if all are eggs, they are true eggs. R. And when we see an image reflected from a mirror, by what signs do we apprehend it to be false? A. By the fact that it cannot be grasped, gives forth no sound, does not move independently, does not live, and by innumerable other properties, which it were tedious to detail. R. I see you are averse to delay, and regard must be borne to your haste. Then, not to recall every particular, if those men also whom we see in dreams, were able to live, speak, be grasped by waking men, and there were no difference between them and those whom when awake and sane we address and see, should we then have any reason to call them false? A. What possible right could we have to do so? R. Therefore if they were true, in exact proportion as they were likest the truth, and as no difference existed between them and the true and false so far as they were, by those or other differences, convicted of being dissimilar; must it not be confessed that similitude is the mother of truth, and dissimilitude of falsehood? A. I have no answer to make, and I am ashamed of my former so hasty assent.
14. R. It is ridiculous if you are ashamed, as if it were not for this very reason that we have chosen this mode of discourse: which, since we are talking with ourselves alone, I wish to be called and inscribed Soliloquies; a new name, it is true, and perhaps a grating one, but not ill suited for setting forth the fact. For since Truth can not be better sought than by asking and answering, and scarcely any one can be found who does not take shame to be worsted in debate, and so it almost always happens that when a matter is well brought into shape for discussion, it is exploded by some unreasonable clamor and petulance, and angry feeling, commonly dissembled, indeed, but sometimes plainly expressed; it has been, as I think, most advantageous, and most answerable to peace, that the resolution was made by thee to seek truth in the way of question by me and answer by thee: wherefore there is no reason why you should fear, if at any point you have unadvisedly tied yourself up, to return and undo the knots; for otherwise there is no escape from hence.
15. A. Thou speakest rightly; but what I have granted amiss I altogether fail to see: unless perchance that that is rightly called false which has some similitude of the true, since assuredly nothing else occurs to me worthy of the name of false; and yet again I am compelled to confess that those things which are called false are so called by the fact that they differ from the true. From which it resuits that that very dissimilitude is the cause of the falsity. Therefore I am disquieted; for I cannot easily call to mind anything that is engendered by contrary causes. R. What if this is the one and only kind in the universe of things which is so? Or are you ignorant, that in running over the innumerable species of animals, the crocodile alone is found to move its upper jaw in eating; especially as scarcely anything can be discovered so like to another thing, that it is not also in some point unlike it? A. I see that indeed; but when I consider that that which we call false has both something like and something unlike the true, I am not able to make out on which side it chiefly merits the name of false. For if I say: on the side on which it is unlike; there will be nothing which cannot be called false: for there is nothing which is not dissimilar to some thing, which we concede to be true. And again, if I shall say, that it is to be called false on that side on which it is similar; not only will those eggs cry out against us which are true on the very ground of their excessive similarity, but even so I shall not escape from his grasp who may compel me to confess that all things are false because I cannot deny that all things are on some side or other similar to each other. But suppose me not afraid to give this answer, that likeness and unlikeness alike give a right to call anything false; what way of escape wilt thou give me? For none the less will the fatal necessity hang over me of proclaiming all things false; since, as has been said above, all things are found to be both similar, on some side, and dissimilar, on some side, to each other. My only remaining resource would be to declare nothing else false, except what was other than it seemed, unless I shrank from again encountering all those monsters, which I flattered myself that I had long since sailed away from. For a whirlpool again seizes me at unawares, and brings me round to own that to be true which is as it seems. From which it results that without a knower nothing can be true: where I have to fear a shipwreck on deeply hidden rocks, which are true, although unknown. Or, if I shall say that that is true which is, it follows, let who will oppose, that there is nothing false anywhere. And so I see the same breakers before me again, and see that all my patience of thy delays has helped me forward nothing at all.
