"The general statement that the mental faculties are class concepts, belonging to descriptive psychology, relieves us of the necessity of discussing them and their significance at the present stage of our inquiry"

This quote by Wilhelm Wundt is referring to the idea that mental professors, such as memory, understanding, and thinking, are ideas that belong to descriptive psychology. Wundt is suggesting that we do not require to go over these ideas and their significance in the current stage of our inquiry. This indicates that we should concentrate on other aspects of psychology, such as the study of habits, rather than on the psychological professors themselves. Wundt is suggesting that we should not be concerned with the specifics of the psychological faculties at this moment in our research study, but rather that we ought to focus on other topics. This quote is an example of Wundt's emphasis on the importance of empirical research study and the need to focus on the study of behavior rather than on the psychological professors themselves.
