In 1887 Volkelt published an article on "Self-observation and psychological analysis", in which he already foreshadows some considerations of the later Würzburg School of thought and thus paves the way for it.

"If the next task of psychology lies in the search for the laws of the processes of consciousness, and if, furthermore, the processes of consciousness are accessible to direct experience, then there can be no nearer and more successful way for the attainment of that task than to start from the determination of the experiential processes of consciousness."
