 Nicholas composed On Conjectures as a letter treatise addressed to Cardinal Cesarini. In chapter 11 of Book One he proposes a scenario where the cardinal views the pope. This scenario leads into his sole explicit description of coniectura. This example of visual perception lets us recognize that we readily make perceptual assertions about what we see or hear. And when we reflect on these perceptual judgments we realize that we go beyond what sensation alone delivers, for we use reason to interpret and make sense of what we see. Reason and sense operate inseparably in our perceptual experience. Reason discriminates, recognizes and may explicitly formulate in language or thought what the experience comes to, for instance, “There’s the pope.”
