  Access to a knowledge basis can itself be thought of in two ways. One might be capable of attaining awareness of what is in fact one's knowledge basis, but without also being capable of being aware that this item is one's knowledge basis. Or, one might actually be capable of attaining awareness that some item is one's knowledge basis. The difference is this: in the first case, one might have an awareness directed at what is in fact a knowledge basis, but without realizing that it is one's knowledge basis; while in the second sort of case, one's awareness is directed at the fact that some item is one's knowledge basis.
