  A key question William confronts is how we acquire concepts and knowledge in the present life. In On the Soul he draws an important distinction. In the case of the first rules of truth and morality, he speaks of God as a mirror or book of all truths in which human beings naturally and without an intermediary, and thus without reliance on sense experience, read these rules. Likewise, God impresses or inscribes on our intellective power the intelligible signs in terms of which these first rules or principles are formulated. Thus, William posits at least some innate concepts; he notes, for example, in On Virtues and Morals   that the concept of the true (veri) is innate (OO I, 124a). God also reveals to some prophets in this life “hidden objects of knowledge to which the created intellect cannot attain except by the gift and grace of divine revelation” (OO II suppl., 211b; Teske 2000, 445).
