We can’t see seeing.
We can’t hear hearing.
But, we can know knowing?
By watching and listening and reflecting it to some degree it becomes possible to assess whether another person sees, hears or knows.
The same is true of one’s self. When we do not know whether to believe or eyes or ears, we want testimony from other senses. But knowledge always says” “trust me.”
Senses only come to know themselves through the dialogue known as common sense.
Faculties are caught in action, listened to, interpreted, spoken about, coordinated and disciplined.
