An important question, however, confronts us here. If human organisation has no part in the essential nature of thinking, what is its function within the whole nature of man? Well, the effects of thinking upon this organisation have no bearing upon the essence of thinking, but they have a bearing upon the origin of the "I," or Ego-consciousness, through thinking. Thinking, in its unique character, constitutes the real Ego, but it does not constitute, as such, the Ego-consciousness. To see this we have but to study thinking with an open mind. The Ego is to be found in thinking. The Ego-consciousness arises through the traces which, in the sense above explained, the activity of thinking impresses upon our general consciousness. The Ego-consciousness thus arises through the physical organisation. This view must not, however, be taken to imply that the Ego-consciousness, once it has arisen, remains dependent on the physical organisation. On the contrary, once it exists it is taken up into thought and shares henceforth thought's spiritual self-subsistence. The Ego-consciousness is built upon human organisation. The latter is the source of all acts of will. Following out the direction of the preceding exposition, we can gain insight into the connection of thought, conscious Ego, and act of will, only by studying first how an act of will issues from human organisation. [4] In a particular act of will we must distinguish two factors: the motive and the spring of action. The motive is a factor of the nature of concept or idea; the spring of action is the factor in will which is directly determined in the human organisation. The conceptual factor, or motive, is the momentary determining cause of an act of will; the spring of action is the permanent determining factor in the individual. The motive of an act of will can be only a pure concept, or else a concept with a definite relation to perception, i.e., an idea. Universal and individual concepts (ideas) become motives of will by influencing the human individual and determining him to action in a particular direction. One and the same concept, however, or one and the same idea, influence different individuals differently. They determine different men to different actions. An act of will is, therefore, not merely the outcome of a concept or an idea, but also of the individual make-up of human beings. This individual make-up we will call, following Eduard von Hartmann, the "characterological disposition." The manner in which concept and idea act on the characterological disposition of a man gives to his life a definite moral or ethical stamp.
