This article presents the author's comments on the article by Keith and Ender on sociology's disciplinary core being reflected in introductory sociology textbooks. The author mentions that Keith and Ender claim that if sociology has a disciplinary core, it "would logically be located in the introductory textbook." Furthermore, since a science is supposed to have a conceptual core, Keith and Ender suggest that sociology may not be a science, or at least is not presented as one in introduction to sociology textbooks. The author states that this comment presents evidence that introduction to sociology textbooks are not reflective of published sociological research, and therefore, the contents of these books' glossaries tell readers little about the current state of the discipline. He emphasizes that Keith and Ender are not alone in claiming that introduction to sociology textbooks reflect this field. He argues that introduction to sociology textbooks are a poor reflection of the discipline. (Contains 1 table and 2 footnotes.)
