  The brief discussion of the summoners raises suspicions about the faculty psychology presented in the final argument of Book V and in Line and Cave. It seems at times that Plato thinks that belonging to each part of the soul are capacities or faculties capable of issuing judgments (cf. 602c-603a; see Burnyeat 1976).  So, for instance, there are the judgments of sense that can and often do conflict with the judgments of reason.  But taken literally, if each faculty has its own objects such that no other faculty can be set over them, then there can be no conflict in judgments. The case of perception poses a special difficulty.  Perception, unlike discursive thought or belief, is aligned not with the so-called rational part of the soul, but with the desiderative part. As we saw in the Phaedo, as well as in the passages about the sightlovers and the summoners, the senses are disparaged as a source of confusion and falsehood. The senses mislead us. One of Plato's complaints seems to be that people rely on perception, or belief relying on perception, with the result that they come to think that what is real is the physical, sensible world. And, perhaps even worse, they come to think that one can understand (know) things about the world such as what makes (for example) a temple beautiful or a stick equal or a person large by appealing to properties that are perceptual or observational or sensible.
