 Nicholas avers that our knowledge of the natural and cultural world embodied in and made systematic in the technical and mechanical and liberal arts will remain “conjectural.” The reason is that we are not dealing with the true reality of mind-independent things whose true forms are one with God. We only encounter the physically located temporal realities that are images of the really real. As he remarks, “the notions that are attained through the assimilations of reason are uncertain, because they are in accord with the images of forms rather than with their true [forms].” (ibid., c.7) Only the concepts of mathematics are not conjectural because we fashion or construct these ideas ourselves. Consequently our conceptions of them can be precise and certain, for as conceptual entities they escape the sorts of change and bodily limits characteristic of the physical world.
