Dialogues of Plato - MobileReference [879]
STRANGER: 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.
STRANGER: But would either of them be if not participating in being?
THEAETETUS: No.
STRANGER: 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.
THEAETETUS: Just so.
STRANGER: 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.
THEAETETUS: True.
STRANGER: 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.
THEAETETUS: Why so?
STRANGER: 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.
STRANGER: 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.
STRANGER: How?
THEAETETUS: Why, because motion itself would be at rest, and rest again in motion, if they could be attributed to one another.
STRANGER: But this is utterly impossible.
THEAETETUS: Of course.
STRANGER: Then only the third hypothesis remains.
THEAETETUS: True.
STRANGER: 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.
STRANGER: And two out of these three suppositions have been found to be impossible.
THEAETETUS: Yes.
STRANGER: 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.
STRANGER: 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.
STRANGER: 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.
THEAETETUS: True.
STRANGER: But does every one know what letters will unite with what? Or is art required in order to do so?
THEAETETUS: Art is required.
STRANGER: What art?
THEAETETUS: The art of grammar.
STRANGER: 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?
THEAETETUS: Yes.
STRANGER: And we shall find this to be generally true of art or the absence of art.
THEAETETUS: Of course.
STRANGER: 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,
