Stranger: When you speak of Movement and Rest, these are things completely opposed to one another, aren't they?
Theaetetus: Of course.
Stranger: At the same time you say of both and of each severally, that they are real?
Theaetetus: I do.
Stranger: And when you admit that they are real, do you mean that either or both are in movement?
Theaetetus: Certainly not.
Stranger: Then, perhaps, by saying both are real you mean they are both at rest?
Theaetetus: No, how could I?
Stranger: So, then, you conceive of reality (realness) as a third thing over and above these two; and when you speak of both as being real, you mean that you are taking both movement and rest together as embraced by reality and fixing your attention on their common association with reality?
Theaetetus: It does seem as if we discerned reality as a third thing, when we say that movement and rest are real.
Stranger: So reality is not motion and rest 'both at once', but something distinct from them.

Those who think that form is unimportant, will miss the spirit as well, while those who cling to form lose the very spirit which they tried to preserve. Form and movement are the secret of life, and the key to immortality.
