Riedel's "trinity" seems to have attracted Hitler's particular attention. A dense penciled line parallels the following passage: "The problem with being objective is that we use objective criteria as the basis for human understanding in general, which means that the objective criteria, that is, the rational criteria, end up serving as the basis for all human understanding, perception and decision-making." By using the five traditional senses to achieve this "objectivity," Riedel declared, human beings exclude the possibility of perceivingthrough the additional seven senses he identifiedthe deeper forces of the world, and are thus unable to achieve that unity of body, mind, and soul. "The human mind never decides things on its own, it is the result of a discourse between the body and the soul," he claimed.
