When one says, for example, that superiority and inferiority is a formation to be found in every human association, though the proposition certainly involves very profound insight into the essence of human nature and human relationship, yet the assertion is so general that it affords little knowledge of particular societary formations. In order to reach such particular knowledge we must study separate types of superiority and inferiority, and we must master the special features of their formation, which in proportion to their definiteness of course lose generality of application.
