The Foreigner Icon

FOREIGNER: Then let us acknowledge the difficulty; and as being and not-being are involved in the same perplexity, there is hope that when the one appears more or less distinctly, the other will equally appear; and if we are able to see neither, there may still be a chance of steering our way in between them, without any great discredit.

THEAETETUS: Very good.

FOREIGNER: Let us enquire, then, how we come to predicate many names of the same thing.

THEAETETUS: Give an example.

FOREIGNER: I mean that we speak of man, for example, under many names—that we attribute to him colours and forms and magnitudes and virtues and vices, in all of which instances and in ten thousand others we not only speak of him as a man, but also as good, and having numberless other attributes, and in the same way anything else which we originally supposed to be one is described by us as many, and under many names.

THEAETETUS: That is true.

FOREIGNER: And thus we provide a rich feast for tyros, whether young or old; for there is nothing easier than to argue that the one cannot be many, or the many one; and great is their delight in denying that a man is good; for man, they insist, is man and good is good. I dare say that you have met with persons who take an interest in such matters—they are often elderly men, whose meagre sense is thrown into amazement by these discoveries of theirs, which they believe to be the height of wisdom.

THEAETETUS: Certainly, I have.

FOREIGNER: Then, not to exclude any one who has ever speculated at all upon the nature of being, let us put our questions to them as well as to our former friends.

THEAETETUS: What questions?

FOREIGNER: Shall we refuse to attribute being to motion and rest, or anything to anything, and assume that they do not mingle, and are incapable of participating in one another? Or shall we gather all into one class of things communicable with one another? Or are some things communicable and others not?—Which of these alternatives, Theaetetus, will they prefer?

THEAETETUS: I have nothing to answer on their behalf. Suppose that you take all these hypotheses in turn, and see what are the consequences which follow from each of them.

FOREIGNER: Very good, and first let us assume them to say that nothing is capable of participating in anything else in any respect; in that case rest and motion cannot participate in being at all.

THEAETETUS: They cannot.

FOREIGNER: But would either of them be if not participating in being?


FOREIGNER: Then by this admission everything is instantly overturned, as well the doctrine of universal motion as of universal rest, and also the doctrine of those who distribute being into immutable and everlasting kinds; for all these add on a notion of being, some affirming that things ‘are’ truly in motion, and others that they ‘are’ truly at rest.


FOREIGNER: Again, those who would at one time compound, and at another resolve all things, whether making them into one and out of one creating infinity, or dividing them into finite elements, and forming compounds out of these; whether they suppose the processes of creation to be successive or continuous, would be talking nonsense in all this if there were no admixture.


FOREIGNER: Most ridiculous of all will the men themselves be who want to carry out the argument and yet forbid us to call anything, because participating in some affection from another, by the name of that other.


FOREIGNER: Why, because they are compelled to use the words ’to be,’ ‘apart,’ ‘from others,’ ‘in itself,’ and ten thousand more, which they cannot give up, but must make the connecting links of discourse; and therefore they do not require to be refuted by others, but their enemy, as the saying is, inhabits the same house with them; they are always carrying about with them an adversary, like the wonderful ventriloquist, Eurycles, who out of their own bellies audibly contradicts them.

THEAETETUS: Precisely so; a very true and exact illustration.

FOREIGNER: And now, if we suppose that all things have the power of communion with one another—what will follow?

THEAETETUS: Even I can solve that riddle.


THEAETETUS: Why, because motion itself would be at rest, and rest again in motion, if they could be attributed to one another.

FOREIGNER: But this is utterly impossible.

THEAETETUS: Of course.

FOREIGNER: Then only the third hypothesis remains.


FOREIGNER: For, surely, either all things have communion with all; or nothing with any other thing; or some things communicate with some things and others not.

THEAETETUS: Certainly.

FOREIGNER: And two out of these three suppositions have been found to be impossible.


FOREIGNER: Every one then, who desires to answer truly, will adopt the third and remaining hypothesis of the communion of some with some.

THEAETETUS: Quite true.

FOREIGNER: This communion of some with some may be illustrated by the case of letters; for some letters do not fit each other, while others do.

THEAETETUS: Of course.

FOREIGNER: And the vowels, especially, are a sort of bond which pervades all the other letters, so that without a vowel one consonant cannot be joined to another.


FOREIGNER: But does every one know what letters will unite with what? Or is art required in order to do so?

THEAETETUS: Art is required.

FOREIGNER: What art?

THEAETETUS: The art of grammar.

FOREIGNER: And is not this also true of sounds high and low?—Is not he who has the art to know what sounds mingle, a musician, and he who is ignorant, not a musician?


FOREIGNER: And we shall find this to be generally true of art or the absence of art.

THEAETETUS: Of course.

FOREIGNER: And as classes are admitted by us in like manner to be some of them capable and others incapable of intermixture, must not he who would rightly show what kinds will unite and what will not, proceed by the help of science in the path of argument? And will he not ask if the connecting links are universal, and so capable of intermixture with all things; and again, in divisions, whether there are not other universal classes, which make them possible?

THEAETETUS: To be sure he will require science, and, if I am not mistaken, the very greatest of all sciences.

FOREIGNER: How are we to call it? By Zeus, have we not lighted unwittingly upon our free and noble science, and in looking for the Sophist have we not entertained the philosopher unawares?

THEAETETUS: What do you mean?

FOREIGNER: Should we not say that the division according to classes, which neither makes the same other, nor makes other the same, is the business of the dialectical science?

THEAETETUS: That is what we should say.

FOREIGNER: Then, surely, he who can divide rightly is able to see clearly one form pervading a scattered multitude, and many different forms contained under one higher form; and again, one form knit together into a single whole and pervading many such wholes, and many forms, existing only in separation and isolation. This is the knowledge of classes which determines where they can have communion with one another and where not.

THEAETETUS: Quite true.

FOREIGNER: And the art of dialectic would be attributed by you only to the philosopher pure and true?

THEAETETUS: Who but he can be worthy?

FOREIGNER: In this region we shall always discover the philosopher, if we look for him; like the Sophist, he is not easily discovered, but for a different reason.

THEAETETUS: For what reason?

FOREIGNER: Because the Sophist runs away into the darkness of not-being, in which he has learned by habit to feel about, and cannot be discovered because of the darkness of the place. Is not that true?

THEAETETUS: It seems to be so.

FOREIGNER: And the philosopher, always holding converse through reason with the idea of being, is also dark from excess of light; for the souls of the many have no eye which can endure the vision of the divine.

THEAETETUS: Yes; that seems to be quite as true as the other.

FOREIGNER: Well, the philosopher may hereafter be more fully considered by us, if we are disposed; but the Sophist must clearly not be allowed to escape until we have had a good look at him.

THEAETETUS: Very good.
