STRANGER: And yet is, because partaking of being.
THEAETETUS: True.
STRANGER: Again, motion is other than the same?
THEAETETUS: Just so.
STRANGER: And is therefore not the same.
THEAETETUS: It is not.
STRANGER: Yet, surely, motion is the same, because all things partake of the same.
THEAETETUS: Very true.
STRANGER: Then we must admit, and not object to say, that motion is the same and is not the same, for we do not apply the terms 'same' and 'not the same,' in the same sense; but we call it the 'same,' in relation to itself, because partaking of the same; and not the same, because having communion with the other, it is thereby severed from the same, and has become not that but other, and is therefore rightly spoken of as 'not the same.'
THEAETETUS: To be sure.
