Because we humans are of a triadic nature--physical, mental, and spiritual--ordinary mechanistic, materialistic procedures of investigation do not enable us to understand human beings. Our methodology of exploration must partake of the same nature as the reality being explored. We cannot understand humans from external, logical study as with objects; humans are subjects. Only in immediate mental and verbal interchange with human beings do we gain insight into their essence. Instead of truth being conceived as a sort of ready-made thing which can be grasped by an effort of thought, and easily transferred and communicated to others, truth about humans can only be gained through participation of the subjects in mutual interchange. Understanding the truth about humans is totally unlike understanding empirical objects; it is the outgrowth of a social act. Only the process, the social activity of dialectical interchange, embodies and reveals human nature because it involves a dynamic intuitive mode of apprehension and communication, the power of attaining to direct knowledge without extraneous rational thought and inference.
