Within the sphere of truth, there can be either truth or falsity. This information is manifold and capable of changing. Being is discovered not by the senses, but by nous . It is composed of opposites, which are mortal, imperishable. But opinion is thereby devoid of nous which is divine and immortal, just as Being is.
Motion is light and darkness.
Things from this standpoint are onta , be-ings . Nous and on are essentially related. Philosophy now becomes ontology, no longer physics.
