STRANGER: And yet you would say that both and either of them equally are?
THEAETETUS: I should.
STRANGER: And when you admit that both or either of them are, do you mean to say that both or either of them are in motion?
THEAETETUS: Certainly not.
STRANGER: Or do you wish to imply that they are both at rest, when you say that they are?
THEAETETUS: Of course not.
STRANGER: Then you conceive of being as some third and distinct nature, under which rest and motion are alike included; and, observing that they both participate in being, you declare that they are.
THEAETETUS: Truly we seem to have an intimation that being is some third thing, when we say that rest and motion are.
STRANGER: Then being is not the combination of rest and motion, but something different from them.
THEAETETUS: So it would appear.
