  The knowledge of which the intellective power is naturally capable extends not just to universals, but also to singulars. For the intellect is naturally directed at the true as the will is at the good, and has as its end knowledge of the first truth, the creator, who is singular. William also notes our knowledge of ourselves and the importance of singular knowledge for our dealings with the world. Unfortunately, he provides no theory of the nature of singular cognition, and this issue must be left on the agenda until taken up by thinkers such as Scotus and Ockham in the late thirteenth and early fourteenth centuries.
