These two lectures are an investigation into the connection, in intellectual history, between epistemology and political philosophy. History offers us five schools of thought on the questions: how are concepts formed, and what do they refer in reality. In these lectures Dr. Ridpath examines the answers even to these questions by leading representatives of each school, and then ties these answers to their political views. The goal is to seek out the connection between the view of the conceptual mind as basically active or passive, objective or subjective, and the advocacy of freedom or foreign dealing with man's mind.
