STRANGER: And shall we call the other a fifth class? Or should we consider being and other to be two names of the same class? THEAETETUS: Very likely. STRANGER: But you would agree, if I am not mistaken, that existences are relative as well as absolute? THEAETETUS: Certainly. STRANGER: And the other is always relative to other? THEAETETUS: True. STRANGER: But this would not be the case unless being and the other entirely differed; for, if the other, like being, were absolute as well as relative, then there would have been a kind of other which was not other than other. And now we find that what is other must of necessity be what it is in relation to some other. THEAETETUS: That is the true state of the case. STRANGER: Then we must admit the other as the fifth of our selected classes. THEAETETUS: Yes. STRANGER: And the fifth class pervades all classes, for they all differ from one another, not by reason of their own nature, but because they partake of the idea of the other. THEAETETUS: Quite true. STRANGER: Then let us now put the case with reference to each of the five. THEAETETUS: How? STRANGER: First there is motion, which we affirm to be absolutely ‘other’ than rest: what else can we say? THEAETETUS: It is so. STRANGER: And therefore is not rest. THEAETETUS: Certainly not. STRANGER: And yet is, because partaking of being. THEAETETUS: True. STRANGER: Again, motion is other than the same? THEAETETUS: Just so. 784
