This is Ritzer's original article applying Kuhn's ideas of "paradigms" to Sociology...the beginning of substantive work in the metatheoretical arena by Ritzer. It appeared in The American Sociologist, Vol. 10, No. 3, August 1975 (pp. 156-167).
These are jpg images...the article divided into 12 sections/pages (the last one is references only...the next to last is mostly references). Please excuse my underlinings.
