The total of knowledge is greater than the ability of any individual to assimilate. Because an individual does not comprehend what he or she does not know, the selection of knowledge by an individual is based on the knowledge posessed. The greater the knowledge posessed, the less likely the individul to discover ignorance. The less the knowledge posessed by the individual, the more likely ignorance is to be revealed. Thus, greater knowledge leads to greater influence by ignorance, and greater ignorance to greater influence by knowledge.
