By (iii) I mean that an account of the general character of what we know must enable us to frame an account of how knowledge is possible as an adjunct within things known.

In any occasion of cognition, that which is known is an actual occasion of experience, as diversified[1] by reference to a realm of entities which transcend that immediate occasion in that they have analogous or different connections with other occasions of experience.
