  If, for all their faults, claims based on sensory information are more reliable than those based on reasoning (about sensory information or anything else), then we ought not appeal to the latter as a basis for judging among claims of the former. One reason he thinks sensory-based claims are the more reliable of the two is that he takes the senses to passively (hence steadily) collect information, in contrast to our mental judgment actively (hence irregularly) organizing or relating information. This is not to say that we will have no problems gauging the warrant for claims based on sensory information as we collect it. Rather, we will have even more problems in gauging claims based on ideas about sensory information after such ideas are that much more removed from a direct and perspicuous relationship to the world as experienced, in our organizing and relating them to other ideas.
