[ 1 .] T o one doubting whether there is, or denying that there is, something of such a nature than which nothing greater can be thought, it is said here [in the Proslogion] that its existence is proved, first because the very one who denies or doubts it
already has it in his mind, since when he hears it spoken of he understands what is said ; and further, because what he under stands is necessarily such that it exists not only in the mind but also in reality. And this is proved by the fact that it is greater to exist both in the mind and in reality than in the mind alone.
For if this same being exists in the mind alone, anything that existed also in reality would be greater than this being, and thus that which is greater than everything would be less than some thing and would not be greater than everything, which is obviously contradictory. Therefore, it is necessarily the case that that which is greater than everything, being already proved to exist in the mind, should exist not only in the mind but also in reality, since otherwise it would not be greater than everything.
[2 .] But he [the Fool] can perhaps reply that this thing is said already to exist in the mind only in the sense that I understand what is said. For could I not say that all kinds of unreal things, not existing in themselves in any way at all, are equally in the mind since if anyone speaks about them I understand whatever he says ? Unless perhaps it is manifest that this being is such that it can be entertained in the mind in a different way from unreal or doubtfully real things, so that I am not said to think of or have in thought what is heard, but to understand and have it in mind, in that I cannot really think of this being in any other way save by understanding it, that is to say, by grasping by certain knowledge that the thing itself actually exists. But if this is the case, first, there will be no difference between having an object in mind (taken as preceding in time) , and understanding that the object actually exists (taken as following

in time) , as in the case of the picture which exists first in the mind of the painter and then in the completed work. And thus it would be scarcely conceivable that, when this object had been spoken of and heard, it could not be thought not to exist in the same way in which God can [be thought] not to exist.
For if He cannot, why put forward this whole argument against anyone denying or doubting that there is something of this kind? Finally, that it is such a thing that, as soon as it is thought of, it cannot but be certainly perceived by the mind as in dubitably existing, must be proved to me by some indisputable argument and not by that proposed, namely, that it must already be in my mind when I understand what I hear. For this is in my view like [arguing that] any things doubtfully real or even unreal are capable of existing if these things are men tioned by someone whose spoken words I might understand, and, even more, that [they exist] if, though deceived about them as often happens, I should believe them [to exist]-which argu ment I still do not believe !
[3.] Hence, the example of the painter having the picture he is about to make already in his mind cannot support this argument. For this picture, before it is actually made, is con tained in the very art of the painter and such a thing in the art of any artist is nothing but a certain part of his very under standing, since as St. Augustine says [In Iohannem, tract. 1 ,
n. 1 6], 'when the artisan is about actually to make a box he has it beforehand in his art. The box which is actually made is not
a living thing, but the box which is in his art is a living thing since the soul of the artist, in which these things exist before their actual realization, is a living thing'. Now how are these things living in the living soul of the artist unless they are identical with the knowledge or understanding of the soul itself? But, apart from those things which are known to belong to the very nature of the mind itself, in the case of any truth perceived by the mind by being either heard or understood, then it cannot be doubted that this truth is one thing and that the understanding which grasps it is another. Therefore even

if it were true that there was something than which nothing greater could be thought, this thing, heard and understood, would not, however, be the same as the not-yet-made picture is in the mind of the painter.

[4.] To this we may add something that has already been mentioned, namely, that upon hearing it spoken of I can so
little think of or entertain in my mind this being (that which is greater than all those others that are able to be thought of,

and which it is said can be none other than God Himself) in terms of an obj ect known to me either by species or genus, as I can think of God Himself, whom indeed for this very
reason I can even think does not exist. For neither do I know the reality itself, nor can I form an idea from some other
things like it since, as you say yourself, it is such that nothing could be like it. For if I heard something said about a man who
was completely unknown to me so that I did not even know whether he existed, I could nevertheless think about him in his very reality as a man by means of that specific or generic
notion by which I know what a man is or men are. However, it could happen that, because of a falsehood on the part of the
speaker, the man I thought of did not actually exist, although
I thought of him nevertheless as a truly existing object-not
this particular man but any man in general. It is not, then, in the way that I have this unreal thing in thought or in mind that
I can have that object in my mind when I hear ' God' or 'some
thing greater than everything' spoken of. For while I was able to think of the former in terms of a truly existing thing which >vas known to me, I know nothing at all of the latter save for the
verbal formula, and on the basis of this alone one can scarcely

or never think of any truth. For when one thinks in this way, one thinks not so much of the word itself, which is indeed a real thing (that is to say, the sound of the letters or syllables) , as of the meaning of the word which is heard. However, it
[that which is greater than everything] is not thought of in the way of one who knows what is meant by that expression thought of, that is, in terms of the thing [signified] or as true
in thought alone. It is rather in the way of one who does not
really know this object but thinks of it in terms of an affection of his mind produced by hearing the spoken words, and who

tries to imagine what the words he has heard might mean.
However, it would be astonishing if he could ever [attain to] the truth of the thing. Therefore, when I hear and understand
someone saying that there is something greater than everything that can be thought of, it is agreed that it is in this latter sense

that it is in my mind and not in any other sense. So rnuch for the claim that that supreme nature exists already in my mind.
[5.J That, however, [this nature] necessarily exists in reality is

demonstrated to me from the fact that, unless it existed, what ever exists in reality would be greater than it and conse
quently it would not be that which is greater than everything that undoubtedly had already been proved to exist in the mind.
To this I reply as follows: if something that cannot even be thought
in the true and real sense must be said to exist in the mind, then
I do not deny that this also exists in my mind in the same way.
But since from this one cannot in any way conclude that it exists also in reality, I certainly do not yet concede that it actually exists, until this is proved to me by an indubitable argument.
For he who claims that it actually exists because otherwise it would not be that which is greater than everything does not consider carefully enough whom he is addressing. For I cer
tainly do not yet admit this greater [than everything] to be
any truly existing thing ; indeed I doubt or even deny it. And I do not concede that it exists in a different way from that if one ought to speak of 'existence' here-when the mind tries to imagine a completely unknown thing on the basis of the
spoken words alone. How then can it be proved to me on that
basis that that which is greater than everything truly exists in reality (because it is evident that it is greater than all others) if I keep on denying and also doubting that this is evident and do not admit that this greater [than everything] is either
in my mind or thought, not even in the sense in which many doubtfully real and unreal things are ? It must first of all be proved to me then that this same greater than everything truly exists
in reality somewhere, and then only \vill the fact that it is greater
than everything make it clear that it also subsists in itself.
[6.J For example : they say that there is in the ocean some where an island which, because of the difficulty (or rather the impossibility) of finding that which does not exist, some have called the 'Lost Island' . And the story goes that it is blessed with all manner of priceless riches and delights in abundance,
much more even than the Happy Isles, and, having no owner or inhabitant, it is superior everywhere in abundance of riches
to all those other lands that men inhabit. Now, if anyone tell

me that it is like this, I shall easily understand what is said, since nothing is difficult about it. But if he should then go on to say, as though it were a logical consequence of this : You cannot any more doubt that this island that is more excellent than all other lands truly exists somewhere in reality than you can doubt that it is in your mind; and since it is more excellent to exist not only in the mind alone but also in reality, there fore it must needs be that it exists. For if it did not exist, any other land existing in reality would be more excellent than it, and so this island, already conceived by you to be more excellent than others, will not be more excellent. If, I say, some one wishes thus to persuade me that this island really exists beyond all doubt, I should either think that he was joking, or I should find it hard to decide which of us I ought to judge the bigger fool-I, if I agreed with him, or he, if he thought that he had proved the existence of this island with any certainty, unless he had first convinced me that its very excellence exists in my mind precisely as a thing existing truly and indubitably and not just as something unreal or doubtfully real.
[7.] Thus first of all might the Fool reply to objections. And if then someone should assert that this greater [than everything] is such that it cannot be thought not to exist (again without any other proof than that otherwise it would not be greater than everything), then he could make this same reply and say : When have I said that there truly existed some being that is 'greater than everything', such that from this it could be proved to me that this same being really existed to such a degree that it could not be thought not to exist? That is why it must first be conclusively proved by argument that there is some higher nature, namely that which is greater and better than all the things that arc, so that from this we can also infer everything else which necessarily cannot be wanting to what is greater and better than everything. When, however, it is said that this supreme being cannot be thought not to exist, it would perhaps
be better to say that it cannot be understood not to exist nor even to be able not to exist. For, strictly speaking, unreal things cannot be understood, though certainly they can be thoughtofin the same way as the Fool thought that God does not exist. I know with

God, both exists and cannot not exist. I do not know, however, whether I can think of myself as not existing while I know with absolute certainty that I do exist ; but if I can, why cannot [I do the same] with regard to anything else I know with the same certainty? If however I cannot, this will not be the dis tinguishing characteristic of God [namely, to be such that He cannot be thought not to exist].

Rather the latter should be demonstrated more firmly and so everything received with very great respect and praise.
