"Three men share the honor of having first seen the impossibility of the psychology of their time : E. von Hartmann, Wm. James and H. Bergson. Modern normal psychology starts with them. But these writers were critics rather than builders ; they saw the impossible, but did not yet clearly see the possible et necessarium. It was in the beginning of the present century that modern normal [?] psychology was really created as a complete science of universal validity and not merely as a scientific fragment like association psychology. By different roads the same end has been reached : Külpe, Marbe and their followers began the analysis of so-called thinking and willing in an exact way, with the result that it was found, firstly, that the variety of the immediate conscious possessions was far greater than had been recognized before, and, secondly, that there exist directing causal agents or factors in psychical life just as in material life, as set forth in the study of biology. Besides this modern psychology of thinking and willing, there came into view several new systems and conceptions of logic, established along different lies by Husserl, Rehmke and myself, which also made it quite evident that the variety within the something which I consciously have is very great"
