"The mind's ability to attend to its own representing activity is a distinct ability, logically presupposed as a condition of experience. (We couldn't be representing objects unless, in all cases of such representing, we could also become conscious of our representing.) ... All consciousness ... is a species of self-consciousness, representing objects is at the same time attending to the mind's activities."

"In any remembering, thinking or imagining, although the object of my intending is some state of affairs or other, I am also potentially aware as I intend that what I am doing is an act of remembering, thinking, or imagining. My asserting that S is P is not an assertion of mine unless I am implicitly aware as I assert that I am asserting, not entertaining the possibility that, S is P."
