 William of Ockham considers Auriol’s perceptual problems, but he concludes that they are not a serious threat. On his view, our perceptual process (which occurs by means of intuitive cognitions) is such that it is infallible: for any such intuitive cognition, if it is of a thing that exists, we will know this fact, and if it is not, we will know this as well. He holds this view even given the possibility that God is deceiving us about such perceptions (e.g., by destroying the object while maintaining the perception of it).
