Excerpt from Pure Sociology: A Treatise the Origin and Spontaneous, Development of Society It was upon my notes as thus classified that in 1897 I delivered two courses of lectures before the Summer School of the University of Chicago, one on Pure Sociology and the other 011 Applied Sociology. These two courses of lectures under the same titles, but with ever increasing volume of data, I repeated in 1898 at the University of West Virginia, and in 1899 at Leland Stanford Junior University. I think I can therefore justly claim the right, after three years more of research along the same lines, to give to the work in which the first of these classes of materials is systematically elaborated the title of Pure Sociology which I have always applied to that class, and should I succeed in systematically collating the materials of the second class and in reducing them to a suitable form for publication, I shall crave permission to give to them for like reasons the title Applied Sociology.
