text: "There are," it is said, "certain natural classes of bodies; we say: 'This is a man,' 'this is a horse.' Then there attend on the bodily natures certain movements of the mind which declare something about the body. And these have a certain essential quality which is sundered from body; for example: 'I see Cato walking.' The senses indicate this, and the mind believes it. What I see, is body, and upon this I concentrate my eyes and my mind. Again, I say: 'Cato walks.' What I say," they continue, "is not body; it is a certain declarative fact concerning body – called variously an 'utterance,' a 'declaration,' a 'statement.' Thus, when we say 'wisdom,' we mean something pertaining to body; when we say 'he is wise,' we are speaking concerning body. And it makes considerable difference whether you mention the person directly, or speak concerning the person."
