The movement of the stars might be compared to that of a choric ballet.
Let us suppose that it had but a limited duration; its motion would be
considered perfect, if viewed as a totality, from beginning to end;
but if considered in its parts only, it would be imperfect. Now if we
suppose that it exists always; then will it always be perfect. If it
be always perfect, there will be neither time nor place where it is
becoming perfect; consequently, it will not even have any desire, and
it will measure nothing, neither by time nor place; and therefore will
not remember either.
