 In the ordinary case of seeing a cow through a picket fence, it is debatable whether presentational phenomenology includes the presence of an extended cow, or whether it includes only those regions of the cow not occluded by the fence (see Noe 2005 for further discussion). If your presentational phenomenology includes only the non-occluded regions, and only presentational phenomenology supplies perceptual justification, the rational powers of experience threaten to be limited. You would not have justification to believe that an extended cow is present just by taking your experience of the cow through the slats at face value. Analogously, if only the facing surface of an object is phenomenally present, you might have justification to believe only that the facing surface is present by taking your experience at face value. Here we might find ourselves back at the “veil of surfaces” discussed in  section 2.2.
